Description

The present invention relates to gaming machines.

Conventionally, in a pachinko game machine, which is a type of game machine, a jackpot lottery is held in response to a game ball entering the first start ball entry port or the second start ball entry port, and a pattern change game is executed based on the result of the jackpot lottery. When a jackpot display result is displayed in the pattern change game, a jackpot game is awarded in which the special ball entry port is opened. When a normal pattern change game is executed in response to a game ball entering the normal start port, and a normal win display result is displayed in the normal pattern change game, a normal win game is awarded in which the second start port is opened.

Among such pachinko gaming machines, those that are generally controlled to various gaming states, as in Patent Document 1, for example, are a non-entry rate improvement state and an entry rate improvement state in which the gaming ball is more likely to enter the second starting entry hole than in the non-entry rate improvement state, and the entry rate improvement state is a more advantageous gaming state for the player than the non-entry rate improvement state.

In addition, such pachinko gaming machines are configured to be controlled to the ball winning rate improved state after the end of a jackpot game, and in addition to being awarded a jackpot game, it is possible to heighten the sense of anticipation for being controlled to the ball winning rate improved state after the end of a jackpot game. Also, when controlled to the ball winning rate improved state after the end of a jackpot game, there are cases where the machine is controlled to a non-ball winning rate improved state when the number of times the pattern variation game executed after the end of a jackpot game has been executed reaches a predetermined number of times.

However, in such gaming machines, it is desirable to improve the control of the gaming state in order to increase the interest in the game.
The present invention has been made in consideration of the problems existing in the conventional technology, and has an object to provide a gaming machine which can increase the interest in the game.

The gaming machine that solves the above problem is a gaming machine in which a jackpot game is awarded after a predetermined jackpot display result is displayed in a pattern change game, the gaming machine comprising: a first start ball entry port through which a game ball can enter; a second start ball entry port through which a game ball can enter; an opening/closing member that operates to take an open state in which a game ball can enter the second start ball entry port and a closed state in which a game ball cannot enter the second start ball entry port; a jackpot lottery means that draws a jackpot lottery in response to the entry of a game ball into the first start ball entry port or the entry of a game ball into the second start ball entry port; a gaming state control means that controls a gaming state; and a variation pattern determination means that determines a variation pattern of the pattern change game, and the gaming states controlled by the gaming state control means include a non-ball entry rate, There are an improved state and an improved ball entry rate state, and the improved ball entry rate state is a game state in which a game ball is more likely to enter the second starting ball entry hole than the non-improved ball entry rate state, and is a game state that may be controlled based on at least the establishment of a first condition or the establishment of a second condition, and the second condition is a condition that is established when a special number of pattern variation games are executed without the big win game being awarded, or a condition that is established when a result of a predetermined lottery regarding the improved ball entry rate state is a specific result, and the first condition is a condition that is established after the end of a predetermined big win game, and the improved ball entry rate state controlled based on the establishment of the first condition is a game state in which a game ball is more likely to enter the second starting ball entry hole than the non-improved ball entry rate state, and is a game state that may be controlled based on the establishment of a second condition or the establishment of a first condition. The probability of winning the jackpot lottery is the same as that of the winning rate improvement state, and the variation patterns that can be determined when the game ball enters the second start ball entry port include a first variation pattern that can be determined when the jackpot lottery is not won and that accompanies a reach effect, and a second variation pattern that can be determined when the jackpot lottery is not won and that does not accompany a reach effect, and the first variation pattern is a variation pattern in which the probability determined in the winning rate improvement state controlled based on the establishment of the first condition is different from the probability determined in the winning rate improvement state controlled based on the establishment of the second condition, and the second variation pattern is a variation pattern in which the probability determined in the winning rate improvement state controlled based on the establishment of the first condition is different from the probability determined in the winning rate improvement state controlled based on the establishment of the second condition. The gist of the invention is that the probability of a winning jackpot being determined in the improved winning jackpot state controlled based on the satisfaction of the first condition is different from the probability of a winning jackpot being determined in the improved winning jackpot state controlled based on the satisfaction of the second condition, and there is a specific second fluctuation pattern in which the second fluctuation pattern that can be determined in the improved winning jackpot state controlled based on the satisfaction of the first condition and the second fluctuation pattern that can be determined in the improved winning jackpot state controlled based on the satisfaction of the second condition have the same fluctuation time, and the specific second fluctuation pattern is a fluctuation pattern that can be determined in both the improved winning jackpot state controlled based on the satisfaction of the first condition and the improved winning jackpot state controlled based on the satisfaction of the second condition, regardless of the number of pattern fluctuation games whose execution is pending.

The present invention can increase interest in games.

[First embodiment]
An embodiment of a pachinko gaming machine will be described below.
In this specification, up, down, left, right, front (front), and back (back) indicate the respective directions as seen by the player.

As shown in Fig. 1, a pachinko gaming machine 10 serving as a gaming machine includes a frame 11. The frame 11 is a member for mounting various components such as a game board 20.
The pachinko gaming machine 10 is equipped with a launch handle 16. For example, the launch handle 16 is provided on the front side of the frame body 11. In the pachinko gaming machine 10, a game ball (game medium) is launched toward a game area 21 of a game board 20 with a strength corresponding to an operation amount (rotation amount) of the launch handle 16. In other words, the pachinko gaming machine 10 is configured so that the launch strength of the game ball can be adjusted by operating the launch handle 16.

The pachinko gaming machine 10 is equipped with a decorative lamp 17. For example, the decorative lamp 17 is provided on the front side of the frame body 11. The decorative lamp 17 has a built-in light-emitting element (not shown) and is configured to be able to emit light, blink, and turn off using the light-emitting element. The decorative lamp 17 executes an effect of emitting light, blinking, and turning off (hereinafter referred to as a light-emitting effect) as one of the effects.

The pachinko gaming machine 10 is equipped with a speaker 18. For example, the speaker 18 is provided on the front side of the frame body 11. As one of the effects, the speaker 18 executes an effect (hereinafter referred to as an audio effect) in which sounds such as human or animal voices, sound effects, and music are output.

The pachinko gaming machine 10 is equipped with an operation button 19 on the front side of the frame 11, in a position that can be operated by the player. The operation button 19 is used, for example, during performances. The operation button 19 may also be used, for example, when setting various settings such as volume settings and light intensity settings.

The pachinko gaming machine 10 is equipped with an information display device 22. For example, the information display device 22 is provided in a position on the gaming board 20 that is visible to the player. The information display device 22 displays various information indicating the control status of the pachinko gaming machine 10.

The information display device 22 is equipped with a first special symbol display unit 22a as a game execution means. The first special symbol display unit 22a is configured to be capable of displaying one or more types of first special symbols. The first special symbol display unit 22a executes a first special symbol changing game (first symbol changing game) as a special symbol changing game, in which a predetermined symbol is changed and displayed, and finally the first special symbol is displayed as a fixed, stopped symbol. In the following description, the "first special symbol changing game" may be abbreviated to "first special game."

The information display device 22 is equipped with a second special symbol display unit 22b as a game execution means. The second special symbol display unit 22b is configured to be capable of displaying one or more types of second special symbols. The second special symbol display unit 22b executes a second special symbol changing game (second symbol changing game) as a special symbol changing game, in which a predetermined symbol is changed and displayed, and finally the second special symbol is displayed as a fixed, stopped symbol. In the following description, the "second special symbol changing game" may be abbreviated to "second special game."

In the following description, when there is no need to distinguish between the first special symbol changing game and the second special symbol changing game, they may be collectively referred to as the "special symbol changing game (symbol changing game)" and the special symbol changing game may be referred to as the "special game." In other words, there are a first special game and a second special game. The first special pattern and the second special pattern are patterns for announcing the results of a lottery (a jackpot lottery described later) that is performed internally in the pachinko gaming machine 10.

In this specification, "variable display" means a state in which the type of the displayed pattern changes over time. In this specification, "fixed stop display" means a state in which the pattern is fixedly displayed and the type of the displayed pattern does not change. In this specification, "fixed stop display" and "derive" have the same meaning when it comes to patterns. The special patterns that can be derived in the first special pattern display section 22a and the second special pattern display section 22b each include a jackpot pattern as a jackpot display result and a loss pattern as a loss display result. When a jackpot pattern is derived in a special game, the player can recognize that a jackpot has occurred. When a loss pattern is derived in a special game, the player can recognize that a loss has occurred.

In this embodiment, the first special game and the second special game are not executed simultaneously. In this embodiment, the second special game is executed in priority to the first special game. In this embodiment, if the jackpot lottery is won, a jackpot symbol is derived in the special game, and the jackpot game is awarded after the special game ends. In other words, the jackpot game is awarded after the special game in which the jackpot lottery was won ends. As will be described in more detail later, the jackpot game is a game in which a large number of prize balls can be won, and is therefore an advantageous game (state) for the player.

In this embodiment, a variable interval time (0.5 seconds in this embodiment) is specified as the time until the start of the next special game is permitted after the special symbol is displayed as a fixed stop and the special game ends. In other words, the variable interval time is the time from the end of the current special game until the start of the next special game is permitted. In other words, the variable interval time is the time until the start of the next special game is permitted, and can also be said to be the time until the start of a jackpot game or the start of a standby state is permitted. A standby state is a state in which neither a variable game nor a jackpot game is being played.

The information display device 22 is equipped with a first special hold display section 22c. The first special hold display section 22c displays information that allows the user to recognize the number of first special games whose execution has been put on hold because the hold conditions have been met but the execution conditions have not yet been met. In the following description, the number of first special games that have been put on hold is referred to as the "first special hold number."

The information display device 22 is equipped with a second special hold display section 22d. The second special hold display section 22d displays information that allows the user to recognize the number of second special games whose execution has been put on hold because the hold conditions have been met but the execution conditions have not yet been met. In the following description, the number of second special games that are on hold is referred to as the "second special hold number."

For example, the maximum value of the first special reserved number and the second special reserved number is each 4. In this manner, execution of the special game can be reserved up to the predetermined reserved number (maximum reserved number).
The information display device 22 includes a normal symbol display section 22e. The normal symbol display section 22e is configured to be capable of displaying one or more types of normal symbols. The normal symbol display section 22e is capable of executing a normal symbol variation game in which a predetermined symbol is variably displayed and a normal symbol is finally displayed as a fixed stop. In the following description, the normal symbol variation game is abbreviated to "normal game". The normal symbols that can be derived to the normal symbol display section 22e include a normal winning symbol and a normal losing symbol. When a normal winning symbol is derived in the normal game, the player can recognize that a normal winning has occurred. When a normal losing symbol is derived in the normal game, the player can recognize that a normal losing has occurred. In this embodiment, when a winning lottery for a normal symbol is won, a normal winning symbol is derived in the normal game, and a normal winning game is awarded after the normal game ends. As will be described in more detail later, normal winning gameplay is advantageous to the player because it makes it easier to establish the reservation conditions for the second special game.

The information display device 22 is equipped with a regular hold display section 22f. The regular hold display section 22f displays information that allows the user to recognize the number of regular games whose execution has been put on hold because the hold conditions have been met but the execution conditions have not yet been met. For example, the maximum number of regular holds is "4."

Next, the game board 20 will be described.
The game board 20 has a surface (front side) of the game board 20 divided into a substantially circular shape by rails, forming a game area 21. The pachinko game machine 10 also has a center frame 26 decorated with various ornaments in the substantially center of the game area 21. The center frame 26 has an opening 26a. The center frame 26 may also be referred to as a center role.

The pachinko gaming machine 10 is equipped with a performance display device 27 as a performance execution means. The performance display device 27 has a display area 27r in which an image is displayed. The performance display device 27 is attached to the game board 20 so that the player can view the display area 27r through the opening 26a of the center frame 26. As one of the performances, the performance display device 27 executes a performance (hereinafter referred to as a display performance) in which an image (picture) that resembles a specified character or letter is displayed. The performance display device 27 also executes a specified notification performance.

In this embodiment, the display effects that can be executed by the effect display device 27 include an effect pattern change game in which effect patterns are displayed in a variable manner in multiple rows, and ultimately a combination of effect patterns is derived. In the following explanation, the effect pattern change game is abbreviated to "effect game." The effect patterns are patterns (decorative patterns) decorated with characters, patterns, etc., and are intended to diversify the display effects. In this embodiment, the effect game is performed by displaying (scrolling) the first, second, and third rows of patterns in a variable manner in a predetermined direction.

The presentation game starts with the start of the special game and ends with the end of the special game. In the presentation game, a combination of presentation symbols corresponding to the special symbols derived in the special game is derived. When a jackpot symbol is derived in the special game, a combination of symbols for a jackpot based on the presentation symbols is derived in the presentation game. For example, a combination of symbols for a jackpot based on the presentation symbols is a combination of symbols in which the presentation symbols in all columns are the same, such as "333" or "777". When a losing symbol is derived in the special game, a losing combination of symbols based on the presentation symbols is derived in the presentation game. For example, a losing combination of symbols based on the presentation symbols is a combination of symbols in which the presentation symbols in at least some columns are different from the presentation symbols in the other columns, such as "787" or "556". In addition, in the presentation game, the presentation symbols may be displayed temporarily before being displayed as a fixed stop. In this specification, a "temporary stop display" refers to a temporary stop state before the performance pattern is displayed in a definite stop state, for example, a state in which the performance pattern is displayed in a fluctuating manner.

The performance game may include a reach performance that is performed by forming a reach. A reach is a state in which the same performance pattern is temporarily displayed in a specific column (the first and third columns in this embodiment) among multiple columns, and the performance pattern in a column other than the specific column (the second column in this embodiment) continues to be displayed in a variable manner. For example, there may be multiple types of reach performances in which the characters that appear and the behavior of the performance patterns differ.

The pachinko game machine 10 is provided with a first start port 28 that opens into the game area 21 below the center frame 26. The first start port 28 is always open so that game balls can enter. In other words, the first start port 28, which serves as the first start ball entry port, is capable of receiving game balls. The pachinko game machine 10 is provided with a first start sensor SE1 that detects game balls that have entered the first start port 28. For example, the first start sensor SE1 is provided in a passage through which game balls that have entered the first start port 28 pass. In this embodiment, when a game ball is detected by the first start sensor SE1, the reservation condition for the first special game can be established, and the payout condition for prize balls is also established. In other words, the first special game can be executed in response to the entry of a game ball into the first start port 28.

The pachinko gaming machine 10 is provided with a second start port 29 that opens into the gaming area 21 below the center frame 26. That is, the second start port 29, which serves as a second start ball entry port, is capable of receiving game balls. The pachinko gaming machine 10 is provided with a second start sensor SE2 that detects game balls that have entered the second start port 29. For example, the second start sensor SE2 is provided in a passage through which game balls that have entered the second start port 29 pass. In this embodiment, when a game ball is detected by the second start sensor SE2, the reservation conditions for the second special game may be established, and the payout conditions for prize balls are also established. That is, the second special game can be executed in response to the entry of a game ball into the second start port 29.

The pachinko gaming machine 10 is equipped with a normal variable member 30 that can be operated in a permissive state (open state) and a restricted state (closed state) in the game area 21. The permissive state is a state in which the game ball can be inserted into the second starting hole 29 or it is easy to insert the ball into the second starting hole 29. The restricted state is a state in which the game ball cannot be inserted into the second starting hole 29 or it is difficult to insert the ball into the second starting hole 29. The pachinko gaming machine 10 is equipped with a normal actuator A1 that operates the normal variable member 30 (shown in FIG. 6). The normal variable member 30 is operated to the permissive state during a normal winning game. In this way, the normal variable member 30 as an opening/closing member operates so that the second starting hole 29 can be inserted into the permissive state in a predetermined open state during a normal winning game.

The pachinko gaming machine 10 has a large prize opening 31 that opens into the gaming area 21 at the lower right of the center frame 26. In other words, the large prize opening 31, which serves as a special ball opening, is capable of receiving game balls. The pachinko gaming machine 10 has a special prize opening sensor SE3 that detects game balls that have entered the large prize opening 31. For example, the special prize opening sensor SE3 is provided in a passage through which game balls that have entered the large prize opening 31 pass. In this embodiment, when a game ball is detected by the special prize opening sensor SE3, the conditions for paying out prize balls are met.

The pachinko gaming machine 10 is equipped with a special variable member 32 that can be operated in a permissive state (open state) and a restricted state (closed state) in the game area 21. The permissive state is a state in which the game ball can be entered into the large prize opening 31 or it is easy to enter the ball. The restricted state is a state in which the game ball cannot be entered into the large prize opening 31 or it is difficult to enter the ball. The pachinko gaming machine 10 is equipped with a special actuator A2 that operates the special variable member 32 (shown in FIG. 6). The special variable member 32 is operated to the permissive state during a jackpot game. In this way, the special variable member 32 as a special opening/closing member is operable so that the large prize opening 31 can be in a permissive state and a restricted state during a jackpot game.

The pachinko game machine 10 is provided with a special passage area 36 downstream of the large prize opening 31 through which a game ball that has entered the large prize opening 31 can pass, and a normal passage area 37. The passage through which a game ball that has entered the large prize opening 31 passes is a passage that branches into a first passage and a second passage, and the special passage area 36 is provided in the first passage, and the normal passage area 37 is provided in the second passage. In other words, the special passage area 36 and the normal passage area 37 are passable by a game ball that has entered the large prize opening 31.

The pachinko game machine 10 is equipped with a special passing sensor SE6 that detects a game ball that has passed through the special passing area 36. In this embodiment, when a game ball is detected by the special passing sensor SE6, a high probability state is granted after the big win game ends. In this way, the special passing sensor SE6 detects that a game ball that has entered the big prize opening 31 has passed through the special passing area 36 (a game ball that has passed through the special passing area 36).

The pachinko game machine 10 is provided with a distribution member 38 that can be operated between a first distribution state and a second distribution state at a point where the passage through which the game ball that entered the large prize opening 31 passes branches. The first distribution state is a state in which the game ball that entered the large prize opening 31 can be distributed to the special passing area 36. The second distribution state is a state in which the game ball that entered the large prize opening 31 can be distributed to the normal passing area 37. The pachinko game machine 10 is provided with a distribution actuator A3 that operates the distribution member 38 (shown in FIG. 6). The distribution member 38 operates to be able to take the first distribution state and the second distribution state, and can be operated from the second distribution state to the first distribution state during a jackpot game.

The pachinko game machine 10 has a gate 33 in the game area 21 to the right of the center frame 26 through which game balls can pass (enter). In other words, the gate 33, which serves as a normal start entry port, is capable of receiving game balls. The gate 33 has a gate sensor SE4 that detects game balls passing through the gate 33 (shown in FIG. 6). In this embodiment, when a game ball is detected by the gate sensor SE4, a reserve condition for the normal game can be established. Then, a normal winning lottery is held in response to the game ball entering the gate 33, and if the normal winning lottery is won, a normal winning game is awarded. In other words, a normal winning game may be awarded in response to the game ball entering the gate 33.

The pachinko gaming machine 10 has a general winning opening 34 that opens into the gaming area 21 to the right of the center frame 26. The pachinko gaming machine 10 has a general winning sensor SE5 that detects a gaming ball that enters the general winning opening 34 (shown in FIG. 6). For example, the general winning sensor SE5 is provided in a passage (not shown) through which a gaming ball that enters the general winning opening 34 passes. In this embodiment, when a gaming ball is detected by the general winning sensor SE5, a condition for paying out a prize ball is established. Note that the pachinko gaming machine 10 may have multiple general winning openings.

The pachinko gaming machine 10 of this embodiment is equipped with a first start port 28, a second start port 29, a big prize port 31, and a general prize port 34 as prize ports. The pachinko gaming machine 10 may be equipped with prize ports other than the above prize ports. A "prize" is when a gaming ball enters a prize port. The pachinko gaming machine 10 is also equipped with components, such as nails and windmills, for changing the behavior of the gaming ball flowing down the play area 21.

Next, the gaming state of the pachinko gaming machine 10 will be described.
The pachinko game machine 10 has a low probability state and a high probability state as game states with different jackpot probabilities. The jackpot probability is the probability of winning a jackpot in a jackpot lottery. The high probability state is a game state in which the jackpot probability is higher than in the low probability state. In other words, the high probability state is a game state in which it is easier to win a jackpot lottery than in the low probability state. In the high probability state, the possibility of winning a jackpot lottery is higher than in the low probability state, making it an advantageous game state for the player. The high probability state is a so-called "probability variable state (probability variable state)". In this way, there are a low probability state and a high probability state in which it is easier to win a jackpot lottery than in the low probability state.

The pachinko game machine 10 has a low base state and a high base state as game states with different ratios of the number of winning balls to the number of game balls shot. The high base state is a game state in which the probability of a game ball entering the second starting hole 29 is higher than in the low base state. The high base state is a so-called "electric support state", and the low base state is a so-called "non-electric support state". In the high base state, the probability of a game ball entering the second starting hole 29 is higher, making it easier for the game ball to enter the second starting hole 29, resulting in a game state that is advantageous to the player (easy ball entry state, improved ball entry rate state). In this way, there are a low base state (non-ball entry rate improved state) and a high base state (ball entry rate improved state) in which the ball entry rate of the game ball entering the second starting hole 29 is higher (easier to enter) than in the low base state.

For example, the high base state can be realized by performing one of the three controls described below, which are arbitrarily selected, or by combining a plurality of controls. The first control is a normal symbol variation time shortening control that shortens the variation time of the normal game compared to the low base state. The second control is a normal symbol probability variation control that varies the probability of winning the normal symbol winning lottery (normal winning probability) to a higher probability than in the low base state. The third control is an opening time extension control that lengthens the total opening time of the normal variable member 30 in one normal winning game compared to the low base state. Note that the opening time extension control may be at least one of the following: a control that increases the number of openings of the normal variable member 30 in one normal winning game compared to the low base state, and a control that lengthens the opening time of one normal variable member 30 in a normal winning game compared to the low base state. In this embodiment, in the high base state, the first and second controls are not performed, and the third control is performed, making it easier for the game ball to enter the second starting hole 29 than in the low base state, but this is not limited to the above, and for example, at least one control selected arbitrarily may be performed.

In this embodiment, the probability of a normal hit in the low base state exceeds 0. Therefore, the normal variable member 30 can be operated to a permissive state in the low base state. The probability of a normal hit in the low base state may be 0. In this case, the normal variable member 30 is not operated to a permissive state in the low base state. In other words, the low base state can be said to be a state in which it is more difficult for a game ball to enter the second starting hole 29 or in which a game ball does not enter the second starting hole 29 compared to the high base state.

The high base state may also be achieved by combining the fourth control, which will be described next. The fourth control is a special symbol fluctuation time shortening control that shortens the fluctuation time of the special game (for example, the average fluctuation time) compared to the low base state. When special symbol fluctuation time shortening control is performed, the high base state becomes a so-called "fluctuation time shortening state" for the special symbol. In contrast, the low base state becomes a so-called "non-fluctuation time shortening state" for the special symbol.

In addition, in this embodiment, the high base state includes a first high base state and a second high base state, which have different conditions for control. The first high base state as the first ball entry rate improvement state is a game state controlled based on the establishment of a first condition among the conditions for controlling the high base state. The first condition in this embodiment is a condition that is established after the end of a jackpot game. The second high base state as the second ball entry rate improvement state is a game state controlled based on the establishment of a second condition, different from the first condition, among the conditions for controlling the high base state. The second condition in this embodiment is a condition that is established when a special number of special games (598 times in this embodiment) are played without a jackpot after being controlled to a low probability state. In other words, the high base state is a game state that may be controlled based on the establishment of the first condition or the establishment of the second condition, and is a game state that is controlled based on the establishment of at least the first and second conditions.

In addition, in this embodiment, the opening manner of the normal variable member 30 during normal winning play differs between the first high base state and the second high base state, and the degree to which the game ball enters the second starting hole 29 differs, but this is not limited to the above, and for example, the opening manner of the normal variable member 30 may be the same. Hereinafter, the first high base state and the second high base state may be collectively referred to as the high base state.

Next, a big win in the pachinko gaming machine 10 will be described.
The pachinko game machine 10 of this embodiment has a plurality of types of jackpot symbols as special jackpot symbols. A type of jackpot is determined for each of the plurality of types of jackpot symbols. A type of jackpot game is determined for each of the plurality of types of jackpot symbols (types of jackpots).

In a jackpot game, a predetermined effect is first performed for a predetermined opening time. In this embodiment, an opening effect is performed as the predetermined effect to notify the start of the jackpot game. In a jackpot game, after the opening time has elapsed, multiple rounds of play are played to open the jackpot opening 31. The number of rounds of play is limited to a predetermined number.

A round of play ends when a first end condition is met in which a predetermined upper limit number ("10" in this embodiment) of game balls enter the large prize opening 31, or when a second end condition is met in which a predetermined upper limit time has elapsed. In other words, the end conditions for each of the multiple rounds of play include a first end condition in which the number of game balls entering the large prize opening 31 becomes the upper limit number, and a second end condition in which the number of game balls entering the large prize opening 31 does not become the upper limit number and a predetermined upper limit time has elapsed. In a round of play, the large prize opening 31 is opened in a predetermined opening manner, and more specifically, it takes an open state when the round of play starts and takes a closed state when the round of play ends. In a round of play, a round performance is performed. In this way, the special variable member 32 operates so that the large prize opening 31 can be in an open state during each of the multiple rounds of play, and when the start conditions for starting each round of play are met, the large prize opening 31 is in an open state, and when the end conditions for ending each round of play are met, the large prize opening 31 is in a closed state. Then, when the final round of play ends in a jackpot game, a predetermined presentation is performed for a predetermined ending time. In this embodiment, the predetermined presentation is an ending presentation that notifies the end of the jackpot game. The jackpot game ends as the ending time passes.

Next, a specific jackpot in the pachinko gaming machine 10 will be described.
As shown in FIG. 2, in this embodiment, of the 100 types of jackpot symbols displayed in the first special symbol display section 22a as the game result of the first special game, 100 types of jackpot symbols are classified as symbols ZA. Also, of the 100 types of jackpot symbols displayed in the second special symbol display section 22b as the game result of the second special game, 25 types of jackpot symbols are classified as symbols Za, 30 types of jackpot symbols are classified as symbols Zb, and 45 types of jackpot symbols are classified as symbols Zc. Thus, in this embodiment, there is one type of jackpot in the first special game, and there are three types of jackpots in the second special game, but this is not limited thereto. Hereinafter, the types of jackpots will be expressed as jackpots based on symbols ZA, Za to Zc, using the types of jackpot symbols. In addition, the type of jackpot game awarded based on the type of jackpot is expressed as a jackpot game based on the patterns ZA, Za to Zc using the type of jackpot pattern.

For a jackpot game based on the symbol ZA, the upper limit for the number of rounds is set to 5. For a jackpot game based on the symbol Za, the upper limit for the number of rounds is set to 10. For a jackpot game based on the symbol Zb, the upper limit for the number of rounds is set to 7, which is less than 10. For a jackpot game based on the symbol Zc, the upper limit for the number of rounds is set to 4, which is less than 7. In this embodiment, the upper limit for the time period for rounds is set to 25 seconds for each jackpot game.

In this embodiment, for each of the multiple rounds of play, an inter-round interval time (1.5 seconds in this embodiment) is set (defined) after the end of the round of play, and when the inter-round interval time has elapsed, the next round of play begins, or the ending time begins.

In addition, in this embodiment, the same opening time (14 seconds in this embodiment) is set for all types of jackpot games, but this is not limited to this, and for example, different opening times may be set depending on the type of jackpot game. In addition, in this embodiment, the ending time is set to 11 seconds, but this is not limited to this, and for example, different ending times may be set depending on the type of jackpot game.

As shown in FIG. 3, for each jackpot game, distribution control information indicating the control contents of the distribution member 38 is set. In this embodiment, the multiple round games include an operating round game in which the distribution member 38 is operated from the second distribution state to the first distribution state and then from the first distribution state to the second distribution state, and the first round game is set as the operating round game. Therefore, when the operating round game starts, the distribution member 38 is operated from the second distribution state to the first distribution state and then from the first distribution state to the second distribution state based on the distribution control information set for the type of jackpot. In a non-operating round game that is not an operating round game, the distribution member 38 is not operated from the second distribution state to the first distribution state and maintains the second distribution state. In this way, the multiple round games include an operating round game that can operate the distribution member 38 to the first distribution state and a non-operating round game that does not operate the distribution member 38 to the first distribution state.

The control contents (distribution control) of the distribution member 38 include short distribution control, in which the distribution member 38 is in the first distribution state for a short period of time, and long distribution control, in which the distribution member 38 is in the first distribution state for a long period of time. In other words, the control contents of the distribution member 38 include multiple types of distribution control that operate the distribution member 38 so that the time in which the distribution member 38 is in the first distribution state differs.

In addition, the distribution control information specifies the start conditions for each distribution control corresponding to each type of jackpot. Specifically, the start conditions for each distribution control are established when the number of game balls detected by the special winning sensor SE3 in the operating round game reaches a specified number. In more detail, the start conditions for the short distribution control are established when the number of game balls detected by the special winning sensor SE3 in the operating round game reaches "1", in the same way for all types of jackpot games. The start conditions for the long distribution control are established when the number of game balls detected by the special winning sensor SE3 in the operating round game reaches "2" in the jackpot game based on the symbols Za to Zc. On the other hand, the start conditions for the long distribution control are not established in the operating round game in the jackpot game based on the symbol ZA.

The distribution control information also defines the end conditions for each distribution control. The end condition for the short distribution control is established when 0.028 s has elapsed since the start condition was established, or when the operating round game ends before 0.028 s has elapsed since the start condition was established. In other words, the short distribution control is a distribution control that operates so that the distribution member 38 takes the second distribution state when the end condition for the round game is not established before a predetermined time has elapsed after the distribution member 38 takes the first distribution state. The short distribution control is also a distribution control that operates so that the distribution member 38 takes the second distribution state when the end condition for the round game is established before a predetermined time has elapsed after the distribution member 38 takes the first distribution state.

The end condition of the long distribution control is established when a predetermined time (predetermined time, 1.4 seconds in this embodiment) has elapsed since the end of the operating round game, regardless of the time that has elapsed since the start condition was established. In this embodiment, the predetermined time is set to be a sufficient time from when the game ball that entered the large prize opening 31 enters the large prize opening 31 (when it is detected by the special prize sensor SE3) until it reaches the distribution member 38. In this embodiment, the interval time between rounds is set to 1.5 seconds, and the end condition of the long distribution control is set to 1.4 seconds, so that a time shorter than the interval time between rounds is set as the end condition of the long distribution control. In other words, the long distribution control is a distribution control in which, when the distribution member 38 is in the first distribution state, a predetermined time has elapsed since the end condition of the round game was established, and the distribution member 38 operates to take the second distribution state.

In this embodiment, the end condition of the short distribution control is set to a time shorter than the time from when the game ball is detected by the special winning sensor SE3 until the game ball reaches the distribution member 38. In addition, the combined time of the time set as the end condition of the short distribution control and the time until the distribution member 38 is operated to change from the first distribution state to the second distribution state is shorter than the time from when the game ball is detected by the special winning sensor SE3 until the game ball reaches the distribution member 38. In this way, when the game ball is detected by the special winning sensor SE3 and the start condition of the short distribution control is established, the distribution member 38 operates from the second distribution state to the first distribution state, but the end condition of the short distribution control is established before the game ball reaches the distribution member 38, and the distribution member 38 operates from the first distribution state to the second distribution state. In other words, the short distribution control is a distribution control in which the distribution member 38 operates to assume a first distribution state when the number of game balls that have entered the large prize opening 31 in each operating round of play becomes "1", and the distribution member 38 operates to assume a second distribution state by the time the game ball reaches the distribution member 38. For this reason, it can be said that the short distribution control is a distribution control that makes it difficult to distribute game balls to the special passing area 36.

In addition, in this embodiment, the time from when the special winning sensor SE3 detects a game ball to when the distribution member 38 is operated to change from the second distribution state to the first distribution state is shorter than the time from when the special winning sensor SE3 detects a game ball to when the game ball reaches the distribution member 38. In this way, when the special winning sensor SE3 detects a game ball and the start condition for the long distribution control is met, the distribution member 38 will operate from the second distribution state to the first distribution state by the time the game ball reaches the distribution member 38.

In addition, in a jackpot game based on the symbols Za to Zc, short distribution control and long distribution control are performed in the first round of play. In a jackpot game based on the symbol ZA, short distribution control is performed in the first round of play, but long distribution control is not performed. Therefore, in a jackpot game based on the symbols Za to Zc, at least an operating round game that allows the game ball to pass through the special passing area 36 is performed, while in a jackpot game based on the symbol ZA, an operating round game that allows the game ball to pass through the special passing area 36 is not performed.

Thus, the operating round game includes a first operating round game in which the distribution member 38 can be operated to take the first distribution state based on the short distribution control, but the distribution member 38 is not operated to take the first distribution state based on the long distribution control. Also, the operating round game includes a second operating round game in which the distribution member 38 can be operated to take the first distribution state based on the short distribution control, and the distribution member 38 can be operated to take the first distribution state based on the long distribution control. Compared to the second operating round game, the first operating round game is a round game in which it is more difficult for a game ball that enters the large prize opening 31 to pass through the special passing area 36. In other words, it can be said that a jackpot based on ZA is less likely to be controlled to a high probability state after the end of the jackpot game than a jackpot based on Za to Zc.

As shown in FIG. 2, if the game ball passes through the special passing area 36 during a jackpot game, a high probability state is granted as the game state after the end of the jackpot game until the specified number of special games (100 times in this embodiment) are completed. Furthermore, this specified number is the same regardless of the type of jackpot determined. On the other hand, if the game ball does not pass through the special passing area 36 during a jackpot game, a low probability state is granted instead of a high probability state as the game state after the end of the jackpot game.

As shown in FIG. 4, the first high base state is a game state that is controlled by the end of a jackpot game. On the other hand, the second high base state is a game state that is controlled by the execution of a special game a special number of times without a jackpot after the control of the low probability state. In this way, even in the high base state in which the game ball is more likely to enter the second starting hole 29 than in the low base state, the trigger (condition) for control is different. In addition, the special number, which is the number of times the special game is executed from the control to the low probability state until the control to the second high base state, is a number greater than the specified number of times that can be controlled to the high probability state after the end of a jackpot game, and is a number greater than the first upper limit number (100 times or 597 times) that can be controlled to the first high base state after the control to the low probability state after the end of a jackpot game.

In this embodiment, the first high base state is a game state that is continuously controlled until a first upper limit number of times (in this embodiment, any one of 100, 597, and 697 times) of a special game is executed without a jackpot. There are multiple types of upper limit numbers for this first upper limit number, and the first upper limit number is a number corresponding to the type of jackpot, the game state when the jackpot lottery is won, and the game state controlled after the jackpot game ends. On the other hand, the second high base state is a game state that is continuously controlled until a predetermined second upper limit number of times (759 times in this embodiment) of a special game is executed without a jackpot. In this embodiment, there is one type of upper limit number for this second upper limit number, and the second upper limit number is the same number of times when the game is controlled to a low probability state and a high probability state after the jackpot game ends. The second upper limit number is a number greater than the first upper limit number and a number greater than the special number. In addition, the second upper limit number of times is a number greater than the inverse of the probability of winning the jackpot lottery in a low probability state (approximately 320), and it can be said that the possibility of winning the jackpot lottery is relatively high even in a low probability state.

Specifically, as shown in FIG. 2, if the jackpot lottery is won and a jackpot based on the Za pattern is determined, the first upper limit number of times is 100 times both when the state is controlled to the high probability state and when the state is controlled to the low probability state after the jackpot game ends. In this way, if the jackpot lottery is won and a jackpot based on the Za pattern is determined, the first upper limit number of times is the same as the specified number of times controlled to the high probability state. Also, if the jackpot lottery is won in a low base state and a jackpot based on the Za pattern is determined, the first upper limit number of times is 100 times when the state is controlled to the low probability state after the jackpot game ends.

On the other hand, if the jackpot lottery is won in a high base state and a jackpot based on the Za symbol is determined, when the jackpot game is controlled to a low probability state after the jackpot game ends, the first upper limit number of times will be 597 times, which is greater than 100 times. Also, if the jackpot lottery is won in a high base state and a jackpot based on the Za symbol is determined, when the jackpot game is controlled to a high probability state after the jackpot game ends, the first upper limit number of times will be 697 times, which is greater than 100 times. Note that these 597 times and 697 times are greater than the reciprocal of the probability of winning the jackpot lottery in a low probability state (approximately 320), and it can be said that the possibility of winning the jackpot lottery is relatively high even in a low probability state.

The high base state is controlled when a special game is executed a special number of times after the end of a jackpot game or after the control of the low probability state, so it is highly likely to be controlled when consecutive jackpots occur (so-called "consecutive wins") or when the game is controlled to a low probability state for a certain period of time (so-called "stuck"). In addition, in a jackpot game based on the pattern ZA, it is highly likely that the game will be controlled to a low probability state after the end of the jackpot game because it is difficult for the game ball to pass through the special passing area 36. On the other hand, in a jackpot game based on the patterns Za to Zc, it is highly likely that the game will be controlled to a high probability state after the end of the jackpot game because it is easy for the game ball to pass through the special passing area 36. In particular, among the jackpot games based on the patterns Za to Zc, the jackpot game based on the pattern Za has a long total opening time of the special variable member 32 in one jackpot game, and can be said to be the most advantageous jackpot game. For this reason, if the jackpot lottery is won in a high base state and a jackpot based on the Za pattern is determined, the first upper limit number of times will be greater than in other cases.For this reason, if a jackpot based on the Za pattern is determined in a high base state, the first upper limit number of times will be greater than in other cases.

In this way, the first high base state is a game state in which the upper limit number of special games that can be controlled after the end of a jackpot game differs between when a jackpot based on pattern Za occurs in the high base state and when it is not. Also, the first high base state is a game state in which the upper limit number of special games that can be controlled after the end of a jackpot game differs between when a jackpot based on pattern Za occurs in the high base state and when it is controlled to a low probability state and when it is controlled to a high probability state.

In particular, when a jackpot based on the Za symbol occurs in the high base state, if the jackpot game is ended and the game is controlled to the high probability state and the first high base state, the 1st to 697th special games are controlled to the first high base state, the 698th special game is controlled to the low base state, and the 699th to 1458th special games are controlled to the second high base state. When a jackpot based on the Za symbol occurs in the high base state and the game is controlled to the low probability state and the first high base state after the jackpot game is ended, the 1st to 597th special games are controlled to the first high base state, the 598th special game is controlled to the low base state, and the 599th to 1358th special games are controlled to the second high base state. In this way, when a jackpot based on the Za symbol occurs in the high base state and the game is controlled to the first high base state after the jackpot game is ended, the number of times the special game is executed from the low base state to the second high base state is one. On the other hand, in other cases, it will be 498 or 598 times.

In other words, when the machine is controlled to the first high base state after the end of a jackpot game and then controlled to the low base state, the number of times the special game is executed from being controlled to the low base state until being controlled to the second high base state is smaller when a jackpot based on the pattern Za occurs in the high base state than otherwise. In particular, when a jackpot based on the pattern Za occurs in the high base state and the machine is controlled to the first high base state after the end of a jackpot game and then controlled to the low base state, the number of times the special game is executed from being controlled to the low base state until being controlled to the second high base state is smaller than the first upper limit number of times, and in particular smaller than the reserved upper limit number of each special game.

In this embodiment, when comparing the total opening time of the special variable member 32 during one jackpot game, the possibility of being controlled to a high probability state after the jackpot game ends, and the number of times the special game is played that is controlled to a high base state after the jackpot game ends, it can be said that the second special game is a more advantageous special game for the player than the first special game.

In this embodiment, the first special game does not have a jackpot where the game ball is likely to pass through the special passing area 36, but the second special game has a jackpot where the game ball is likely to pass through the special passing area 36. For this reason, in this embodiment, the first special game is won in a low base state and the second special game is played during the 100 special games controlled to the first high base state after the jackpot game ends, and the second special game is played to win a jackpot based on the patterns Za to Zc, which is an advantageous game progression for the player. In particular, in this embodiment, when the second special game is played and a jackpot based on the pattern Za is won, the game progresses advantageously for the player, even though it spans one special game after the jackpot game ends, and the game progresses advantageously for the player.

In this embodiment, a jackpot based on the symbol ZA corresponds to the first jackpot, and a jackpot based on the symbol Za corresponds to the specific jackpot and the second jackpot.
In this embodiment, when a jackpot based on the symbol Za occurs in a high base state, the first condition that is established after the jackpot game based on the symbol Za ends corresponds to the first special condition, and when a jackpot based on the symbol Za occurs in a low base state, the first condition that is established after the jackpot game based on the symbol Za ends corresponds to the second special condition. In this embodiment, the second condition corresponds to the third special condition.

In this embodiment, when a jackpot based on the pattern ZA is reached, the first condition that is met after the jackpot game based on the pattern ZA ends corresponds to the first specific condition, and when a jackpot based on the pattern Za is reached in a high base state, the first condition that is met after the jackpot game based on the pattern Za ends corresponds to the second specific condition. In this embodiment, the second condition corresponds to the third specific condition.

In this embodiment, the combination of 597 times and 100 times as the first upper limit number of times corresponds to the combination of the first number and the second number of times. In this embodiment, 759 times as the second upper limit number of times corresponds to the predetermined number of times. In this embodiment, 100 times, which is the upper limit number of times controlled to the high base state, corresponds to the regulated number of times. In this embodiment, 599 times, which is the number of times the special game is executed from when it is controlled to the low probability state until it is controlled to the second high base state, corresponds to the special number of times.

As shown in FIG. 5, in this embodiment, the winning probability of a normal winning lottery (normal winning probability) is set to the same probability (65535/65536) in all base states. Thus, in this embodiment, the normal winning lottery is a lottery that has the same winning probability in the low base state, the first high base state, and the second high base state, but is not limited to this, and may be a lottery that has a different winning probability in at least one of the low base state, the first high base state, and the second high base state.

The fluctuation time of the normal game is the same (200 ms) in the low base state, the first high base state, and the second high base state, but is not limited to this. For example, it may be different in at least one of the low base state, the first high base state, and the second high base state, or it may be the same time but with different determination probabilities. In addition, the fluctuation interval time of the normal game is also the same (500 ms) in the low base state, the first high base state, and the second high base state.

There are three types of normal winning patterns displayed on the normal pattern display section 22e as the game result of the normal game, FZA to FZC, and each of the three types of patterns FZA to FZC is determined with the same probability (1/3), but this is not limited to the above, and for example, at least one of the patterns may be determined with a different probability, and there may be one type, two types, or four or more types of patterns.

As the opening mode of the normal variable member 30 in one normal winning game, in the low base state, it is controlled to the open state with an upper limit of 32 ms in all normal winning games, while in the second high base state, it is controlled to the open state with an upper limit of 5400 ms in all normal winning games. Also, as the opening mode of the normal variable member 30 in one normal winning game, in the first high base state, in a normal winning game based on the pattern FZA, it is controlled to the open state for 3000 ms, controlled to the closed state for 1000 ms, and controlled to the open state for 2000 ms until the end condition is established. In a normal winning game based on the pattern FZB, it is controlled to the open state for 2000 ms, controlled to the closed state for 1000 ms, and controlled to the open state for 3000 ms until the end condition is established. In normal winning games based on the FZC pattern, the machine is controlled to the open state for 2500 ms, the closed state for 1000 ms, and the open state for 2500 ms until the end condition is met.

In this way, the opening mode of the normal variable member 30 is longer in the first high base state and the second high base state than in the low base state in the total upper limit opening time during which the second starting hole 29 can be in an open state in one normal winning game. In addition, while there are multiple types of opening modes for the opening mode of the normal variable member 30 in the first high base state, there is only one type of opening mode in the second high base state. The multiple types of opening modes in the first high base state are different from the one type of opening mode in the second high base state in that the upper limit number of times the normal variable member 30 can be in an open state in one normal winning game and the total upper limit opening time during which the second starting hole 29 can be in an open state in one normal winning game are different. In this embodiment, as the opening mode of the normal variable member 30, any of the multiple types of opening modes in the first high base state corresponds to the first opening mode and the second opening mode.

In addition, the total upper limit open time during which the second start port 29 can be in an open state during one normal hit game differs between the first high base state and the second high base state, and the total upper limit open time during which the second start port 29 can be in an open state during one normal hit game is longer in the second high base state than in the first high base state. Also, the upper limit open number of times that the normal variable member 30 can be in an open state during one normal hit game differs between the normal hit game granted in the first high base state and the normal hit game granted in the second high base state.

The multiple types of opening modes in the first high base state have a multiple upper limit number of times that the normal variable member 30 can be in the open state in one normal hit game. In addition, the multiple types of opening modes in the first high base state have the same total upper limit opening time that the second starting port 29 can be in the open state in one normal hit game, the same upper limit number of times that the normal variable member 30 can be in the open state in one normal hit game, and the same closed time that the normal variable member 30 can be in the closed state in one normal hit game. On the other hand, the multiple types of opening modes in the first high base state have different upper limit opening times that the second starting port 29 can be in the open state once.

In addition, the upper limit control time for normal hit games is the same for all types of normal hit games in the first high base state (6000 ms), while it is the same for all types of normal hit games in the second high base state (5400 ms). In other words, the upper limit control time for normal hit games is shorter in the second high base state than in the first high base state. As a result, in the second high base state, the total upper limit open time during which the second start port 29 can be in an open state in one normal hit game is shorter than in the first high base state, but the normal hit game is consumed faster. In addition, in the first high base state, there are multiple types of opening modes of the normal variable member 30 compared to the second high base state, and it is possible to make it more difficult to adjust the launch timing of the game ball so that it is easier to enter the second start port 29, thereby improving the technical intervention of the player.

In this embodiment, the probability of a jackpot is set to 205/65536 (approximately 1/320) in a low probability state and 995/65536 (approximately 1/66) in a high probability state. The number of prize balls is set to "2" when a game ball is detected by the first start sensor SE1, "1" when a game ball is detected by the second start sensor SE2, "15" when a game ball is detected by the special winning sensor SE3, and "4" when a game ball is detected by the general winning sensor SE5.

Next, the electrical configuration of the pachinko gaming machine 10 will be described.
6, the pachinko game machine 10 is provided with a main control board 40 on the back side (rear) of the game board 20. The main control board 40 performs various processes and outputs control signals (control commands) according to the results of the processes.

The pachinko game machine 10 also has a sub-control board 41 on the back (rear) of the game board 20. The sub-control board 41 executes a predetermined process based on a control signal input from the main control board 40. For example, the sub-control board 41 executes processes for executing light emission effects by the decorative lamps 17, audio effects by the speaker 18, and display effects by the effect display device 27.

The pachinko game machine 10 also has a power supply unit 60 on the back (rear) of the game board 20. The power supply unit 60 is a unit that supplies power to the main control board 40 and the sub-control board 41 when the power switch 60a is switched to the on state.

The pachinko gaming machine 10 of this embodiment is equipped with a backup function. The backup function is a function that internally stores (backs up) various information related to game control even if the power supply from an external power source is stopped, and restores game control based on the various information stored when the power supply is started. Here, the various information to be backed up includes game information related to the progress of the game. For example, the game information includes information related to special games, information related to jackpot games, information related to the game status, and information related to the payout of prize balls. In this embodiment, the main control board 40 and the sub-control board 41 are equipped with a backup function, but the sub-control board 41 does not have to be equipped with a backup function.

First, the main control board 40 will be described.
The main control board 40 includes a main control CPU 40a, a main control ROM 40b, a main control RAM 40c, and an RWM clear switch 40d. The main control CPU 40a executes a main control program to perform various processes.

The main control ROM 40b stores a main control program, tables used in a predetermined lottery, and judgment values. The main control ROM 40b also stores a plurality of types of fluctuation patterns. The fluctuation pattern is information that can specify the fluctuation time from when the special game is started to when the special game is ended. In this embodiment, the fluctuation pattern is information that can specify the presentation content of the presentation game that is played from when the special game is started to when the special game is ended. Note that the fluctuation pattern does not have to be information that can specify the presentation content of the presentation game that is played from when the special game is started to when the special game is ended.

The variation patterns include a jackpot variation pattern, a miss reach variation pattern, and a miss variation pattern. In this embodiment, the jackpot variation pattern is determined as the performance content of the performance game, which is a performance content that finally derives a jackpot pattern combination through a reach performance, and a performance content that derives a jackpot pattern combination without a reach performance. In other words, in this embodiment, the jackpot variation pattern can be determined when the jackpot lottery is won, and is either a variation pattern with a reach performance or a variation pattern without a reach performance, but there may be no variation pattern without a reach performance. In the miss reach variation pattern, the performance content of the performance game is determined as the performance content that finally derives a miss pattern combination through a reach performance. In other words, the miss reach variation pattern can be determined when the jackpot lottery is not won, and is a variation pattern with a reach performance. The miss variation pattern is a variation pattern that is determined as the content of the presentation game, and ultimately leads to a miss symbol combination without going through a reach presentation. In other words, the miss variation pattern can be determined when the jackpot lottery is not won, and is a variation pattern that does not involve a reach presentation.

The main control RAM 40c is configured to be able to store various information that is rewritten during operation of the pachinko gaming machine 10. Information stored in the main control RAM 40c includes, for example, flags, counters, and timers. The main control board 40 is also configured to be able to generate random numbers. For example, the random numbers may be generated as hardware random numbers or software random numbers.

The RWM clear switch 40d is configured to be operable to instruct the initialization of various types of backed-up information. In this embodiment, the various types of backed-up information are initialized by turning on the power while the RWM clear switch 40d is in the on state (operated).

The main control CPU 40a and sensors SE1 to SE6 are connected. The main control CPU 40a is configured to be able to input the detection signals that are output when sensors SE1 to SE6 detect a game ball.

The main control CPU 40a and the actuators A1 to A3 are connected. The main control CPU 40a is configured to be able to control the operation of the actuators A1 to A3. The main control CPU 40a and the information display device 22 are connected. The main control CPU 40a is configured to be able to control the display contents of the information display device 22.

Next, the sub-control board 41 will be described.
The sub-control board 41 and the main control board 40 are connected to each other. The pachinko gaming machine 10 is configured so that a control signal can be output in one direction from the main control board 40 to the sub-control board 41.

The sub-control board 41 is equipped with a sub-control CPU 41a, a sub-control ROM 41b, and a sub-control RAM 41c. The sub-control CPU 41a executes a sub-control program to perform various processes (e.g., processes related to performance). The sub-control ROM 41b stores the sub-control program, tables used in the lottery, and judgment values. The sub-control ROM 41b stores display performance data related to the display performance in the performance display device 27. The sub-control ROM 41b stores light-emitting performance data related to the light-emitting performance in the decorative lamp 17. The sub-control ROM 41b stores audio performance data related to the audio performance in the speaker 18.

The sub-control RAM 41c is configured to be capable of storing various information that is appropriately rewritten during operation of the pachinko gaming machine 10. Information stored in the sub-control RAM 41c includes, for example, flags, counters, and timers. The sub-control board 41 is also configured to be capable of generating random numbers. For example, the random numbers may be generated as hardware random numbers or software random numbers.

The sub-control CPU 41a and the performance display device 27 are connected. The sub-control CPU 41a is configured to be able to control the display mode of the performance display device 27. The sub-control CPU 41a and the decorative lamp 17 are connected. The sub-control CPU 41a is configured to be able to control the light emission mode of the decorative lamp 17. The sub-control CPU 41a and the speaker 18 are connected. The sub-control CPU 41a is configured to be able to control the output mode of the speaker 18. The sub-control CPU 41a and the operation button 19 are connected. The sub-control CPU 41a is configured to be able to input an operation signal indicating that the operation button 19 has been operated.

Next, various processes performed in the pachinko gaming machine 10 will be described.
First, the special symbol input process performed by the main control CPU 40a will be described. The special symbol input process is performed as an interrupt process.

In the special symbol input process, the main control CPU 40a determines whether or not a gaming ball has entered the first start hole 28 based on whether or not a detection signal has been input from the first start sensor SE1.
When a game ball enters the first starting hole 28, the main control CPU 40a judges whether the first special reserved number stored in the main control RAM 40c is less than the upper limit number ("4" in this embodiment). When the first special reserved number is less than the upper limit number, the main control CPU 40a updates the first special reserved number stored in the main control RAM 40c by adding "1". This establishes the reservation condition (first reservation condition) of the first special game. That is, the entry of a game ball into the first starting hole 28 can be used as a trigger to reserve the execution of the first special game. In this embodiment, the main control CPU 40a, which reserves the execution of the first special game (special game) with a predetermined upper limit number (reservation upper limit number) as an upper limit in response to the entry of a game ball into the first starting hole 28, corresponds to the reservation means. In this process, the main control CPU 40a controls the information display device 22 to display the updated first special reserved number. In addition, the main control CPU 40a sets information capable of identifying the updated first special reserved number (hereinafter referred to as the first reserved number command) in the output buffer. The information (control command) set in the output buffer is output to the sub-control board 41 in the next or subsequent interrupt processing.

Next, the main control CPU 40a acquires random numbers generated in the main control board 40, and stores random number information based on the acquired random numbers in the main control RAM 40c. For example, the random numbers are random numbers used in the jackpot lottery, random numbers used to determine the jackpot symbol, and random numbers used to determine the variation pattern. In this process, the main control CPU 40a stores the random number information so that it is possible to identify that it is random number information for the first special game and the storage order of the random number information. In this embodiment, by storing the random number information for the first special game in the main control RAM 40c, it is possible to suspend the execution of the first special game until the execution conditions of the first special game are met. In this way, it is possible to suspend the execution of the first special game (special game) when a game ball enters the first starting hole 28. The random number information may be the acquired random number itself, or may be information obtained by processing the random number using a predetermined method.

When no game ball has entered the first start hole 28, when the first special reserved number is not less than the upper limit number, and when random number information for the first special game has been stored in the main control RAM 40c, the main control CPU 40a determines whether or not a game ball has entered the second start hole 29 based on whether or not a detection signal has been input from the second start sensor SE2. When no game ball has entered the second start hole 29, the main control CPU 40a ends the special symbol input process.

When a game ball enters the second starting hole 29, the main control CPU 40a determines whether the second special reserved number stored in the main control RAM 40c is less than the upper limit number ("4" in this embodiment). If the second special reserved number is not less than the upper limit number, the main control CPU 40a ends the special symbol input process. If the second special reserved number is less than the upper limit number, the main control CPU 40a adds "1" to the second special reserved number stored in the main control RAM 40c and updates it. This establishes the reservation condition (second reservation condition) of the second special game. In other words, the entry of a game ball into the second starting hole 29 can be used as a trigger to reserve the execution of the second special game. In this embodiment, the main control CPU 40a, which reserves the execution of the second special game (special game) up to a predetermined upper limit number (reservation upper limit number) in response to the entry of a game ball into the second starting hole 29, corresponds to the reservation means. In this process, the main control CPU 40a controls the information display device 22 to display the updated second special reserved number. The main control CPU 40a also sets information that can identify the updated second special reserved number (hereinafter referred to as the second reserved number command) in the output buffer.

Next, the main control CPU 40a acquires the random numbers generated within the main control board 40, and stores random number information based on the acquired random numbers in the main control RAM 40c. In this process, the main control CPU 40a stores the random number information so that it is possible to identify that it is random number information for the second special game, and the order in which the random number information is stored. In this embodiment, by storing the random number information for the second special game in the main control RAM 40c, it is possible to suspend the execution of the second special game until the execution conditions for the second special game are met. In this way, the execution of the second special game (special game) can be suspended when a game ball enters the second starting hole 29.

Next, the special symbol start process performed by the main control CPU 40a will be described. The special symbol start process is performed as an interrupt process.
In the special symbol start process, the main control CPU 40a judges whether the execution conditions of the special game are satisfied. The main control CPU 40a judges positively when neither a jackpot game nor a special game is being played, and judges negatively when a jackpot game or a special game is being played. If the execution conditions of the special game are not satisfied, the main control CPU 40a ends the special symbol start process.

On the other hand, if the conditions for executing the special game are met, the main control CPU 40a judges whether the second special reserved number stored in the main control RAM 40c is "1" or more. If the second special reserved number is "1" or more, the main control CPU 40a performs a predetermined process so that the conditions for executing the second special game are met and the second special game is started. On the other hand, if the second special reserved number is not "1" or more, the main control CPU 40a judges whether the first special reserved number stored in the main control RAM 40c is "1" or more. If the first special reserved number is "1" or more, the main control CPU 40a performs a predetermined process so that the conditions for executing the first special game are met and the first special game is started. In this way, the main control CPU 40a executes the second special game in priority to the first special game. On the other hand, if the first special reserved number is not "1" or more, the main control CPU 40a ends the special pattern start process. In addition, when the special game or jackpot game is not in progress and each special reserved number is "0", the main control CPU 40a will control the game to a standby state in which the special game and jackpot game are not being executed.

When starting the first special game, the main control CPU 40a updates the first special reserved number stored in the main control RAM 40c by subtracting "1". In this process, the main control CPU 40a controls the information display device 22 so that the updated first special reserved number is displayed. Next, the main control CPU 40a reads out the random number information for the first special game from the main control RAM 40c, which is the first-stored random number information. After reading out the first-stored random number information, the main control CPU 40a erases the random number information from the main control RAM 40c.

Next, the main control CPU 40a judges whether or not a jackpot will be won based on the read random number information and the jackpot judgment value stored in the main control ROM 40b. The judgment of whether or not a jackpot will be won is, for example, judged by whether or not the value of the random number specified from the random number information matches the jackpot judgment value corresponding to the current probability state. The judgment of whether or not a jackpot will be won may also be judged by whether or not the value obtained by adding the value of the random number specified from the random number information and the jackpot judgment value exceeds a predetermined value. In this way, the main control CPU 40a performs a jackpot lottery according to the entry of the game ball into the first starting hole 28, and judges whether or not a jackpot will be won. In this embodiment, the main control CPU 40a that executes such processing corresponds to the jackpot lottery means (jackpot judgment means).

When a jackpot is won, the main control CPU 40a determines the jackpot pattern derived in the first special game and the variation pattern of the first special game. For example, the main control CPU 40a determines the jackpot pattern derived in the first special game and the variation pattern of the first special game by drawing lots using the random number information for the first special game that has been read out. In this embodiment, the main control CPU 40a that executes such processing corresponds to the jackpot type determination means. In addition, in this embodiment, the main control CPU 40a that determines the variation pattern based on a predetermined determination condition corresponds to the variation pattern determination means. When the jackpot pattern derived in the first special game is determined, the main control CPU 40a sets information (hereinafter referred to as a pattern command) that can identify the determined jackpot pattern in the output buffer. When the variation pattern of the first special game is determined, the main control CPU 40a sets information (hereinafter referred to as a game start command) that can identify the determined variation pattern and instructs the start of a presentation game based on the variation pattern in the output buffer. After setting the symbol command and the first game start command in the output buffer, the main control CPU 40a ends the special symbol start process.

On the other hand, in the case of a loss that does not result in a jackpot, the main control CPU 40a determines the loss symbol derived in the first special game and the variation pattern of the first special game. For example, the main control CPU 40a determines the loss symbol derived in the first special game and the variation pattern of the first special game by a lottery using the read random number information for the first special game. In this embodiment, the main control CPU 40a, which determines the variation pattern based on a predetermined determination condition, corresponds to the variation pattern determination means. When the loss symbol derived in the first special game is determined, the main control CPU 40a sets information (hereinafter referred to as a pattern command) capable of identifying the determined loss symbol in the output buffer. When the variation pattern of the first special game is determined, the main control CPU 40a sets a game start command that can identify the determined variation pattern and is based on the variation pattern in the output buffer. After setting the pattern command and the first game start command in the output buffer, the main control CPU 40a ends the special pattern start process.

When the second special game is started, the main control CPU 40a performs the same control as that when the first special game is started. That is, the main control CPU 40a subtracts the second special reserved number, performs a jackpot lottery (jackpot judgment), determines a jackpot pattern or a non-jackpot pattern based on the result of the jackpot lottery, determines a variation pattern based on the result of the jackpot lottery, and sets the pattern command and the game start command. Thus, in this embodiment, the main control CPU 40a performs a jackpot lottery in response to the entry of a game ball into the second start hole 29 and judges whether a jackpot will be obtained. In this embodiment, the main control CPU 40a that executes such processing corresponds to a jackpot lottery means (jackpot judgment means). Also, in this embodiment, the jackpot lottery can be said to include a jackpot lottery for the first special game performed in response to the entry of a game ball into the first start hole 28 and a jackpot lottery for the second special game performed in response to the entry of a game ball into the second start hole 29. The main control CPU 40a then ends the special pattern start process.

Then, when the special symbol start process is completed, the main control CPU 40a executes a special game by performing a process other than the special symbol start process. Specifically, the main control CPU 40a controls the information display device 22 so that a special game is started. The main control CPU 40a measures the change time set in the change pattern determined in the special symbol start process. Then, the main control CPU 40a controls the information display device 22 so that the special symbol determined in the special symbol start process is derived when the change time set in the change pattern has elapsed. In this way, based on the result of the jackpot lottery, the first special symbol display unit 22a of the information display device 22 can execute the first special game as a special game in response to the entry of a game ball into the first start hole 28, and the second special symbol display unit 22b of the information display device 22 can execute the second special game as a special game in response to the entry of a game ball into the second start hole 29. In addition, when the change time set for the change pattern determined in the special pattern start process has elapsed, the main control CPU 40a issues an instruction to stop the change of the performance patterns, and sets information (hereinafter referred to as the game end command) in the output buffer for deriving a pattern combination based on the performance patterns.

By executing this special symbol start process, when a random number value related to a special game is stored, the main control CPU 40a will determine whether or not the special game will result in a jackpot in the order of the earliest total acquisition order, regardless of whether the random number value is related to the first special game or the second special game, and will execute the special game. In other words, the special game will be executed in the order in which the game balls enter the first start hole 28 and the second start hole 29.

Next, the big win processing performed by the main control CPU 40a will be described.
In the jackpot process, the main control CPU 40a performs control to award a jackpot game based on the jackpot symbol (type of jackpot) determined in the special symbol start process. That is, the main control CPU 40a awards a jackpot game by executing the jackpot process.

When the special game of the jackpot ends, the main control CPU 40a first sets information capable of identifying the start of the opening time (hereinafter referred to as the opening command) in the output buffer. When the opening time has elapsed, the main control CPU 40a performs processing to execute a round of play. Specifically, the main control CPU 40a controls the special actuator A2 so that the large prize opening 31 is opened based on an opening pattern determined by the jackpot pattern (type of jackpot), and starts the round of play. After starting the round of play, when the first or second ending condition is established, the main control CPU 40a controls the special actuator A2 so that the large prize opening 31 is closed, and ends the round of play. The main control CPU 40a repeats such processing to execute the round of play until the specified number of rounds of play are completed.

In addition, the main control CPU 40a sets information capable of identifying the start of a round of play (hereinafter referred to as a round command) in the output buffer each time a round of play is started.In addition, the main control CPU 40a sets information capable of identifying the end of a round of play (hereinafter referred to as a round end command) in the output buffer each time a round of play is ended.

In particular, during an operation round play in which the distribution member 38 is operated from the second distribution state to the first distribution state among multiple rounds of play, the main control CPU 40a controls the distribution actuator A3 and controls the operation of the distribution member 38 based on the distribution control information defined for the jackpot pattern (type of jackpot).

Specifically, the main control CPU 40a counts the number of game balls that enter the large prize opening 31 during an operating round game based on the detection signal from the special prize sensor SE3. Note that in this embodiment, the main control CPU 40a counts the number of game balls that enter the large prize opening 31 not only during an operating round game but also during a non-operating round game based on the detection signal from the special prize sensor SE3.

When the main control CPU 40a determines, by referring to the distribution control information set for the jackpot pattern (type of jackpot), that the number of game balls entering the large prize opening 31 is the number of balls that satisfies the condition for starting the short distribution control, the condition for starting the short distribution control is met and the short distribution control is started. The main control CPU 40a then performs the short distribution control until the condition for terminating the short distribution control is met, and when the condition for terminating the short distribution control is met, it operates the distribution member 38 from the first distribution state to the second distribution state to end the short distribution control.

In detail, when any of the types of jackpots has been determined, the start condition of the short distribution control is met when the number of game balls entering the big prize opening 31 in each operating round of play reaches "1", and the main control CPU 40a operates the distribution member 38 to take the first distribution state based on the short distribution control. The main control CPU 40a then counts the elapsed time since the start condition of the short distribution control was met. When a predetermined time (0.028 s in this embodiment) has elapsed, or when the end condition of each operating round of play is met, the end condition of the short distribution control is met, and the main control CPU 40a operates the distribution member 38 to take the second distribution state.

When the main control CPU 40a determines, by referring to the distribution control information set for the jackpot pattern (type of jackpot), that the number of game balls entering the large prize opening 31 is the number of balls that satisfies the condition for starting the long distribution control, the condition for starting the long distribution control is met and the long distribution control is started. The main control CPU 40a then performs the long distribution control until the condition for ending the long distribution control is met, and when the condition for ending the long distribution control is met, it operates the distribution member 38 from the first distribution state to the second distribution state to end the long distribution control.

In more detail, when a jackpot based on the symbols Za to Zc is determined, the condition for starting the long distribution control is met when the number of game balls entering the large prize opening 31 in the first round of play as the second operating round of play reaches "2", and the main control CPU 40a operates the distribution member 38 to assume the first distribution state based on the long distribution control. Note that when a jackpot based on the symbol ZA is determined, the main control CPU 40a does not perform long distribution control in the first round of play.

When the game ball passes through the special passing area 36 during a jackpot game, the main control CPU 40a stores information indicating the game ball's passage into the special passing area 36 in the main control RAM 40c. In addition, when the game ball passes through the special passing area 36 during a jackpot game, the main control CPU 40a sets information capable of identifying the game ball's passage into the special passing area 36 (hereinafter referred to as a special passing command) in the output buffer.

When the final round of play ends, the main control CPU 40a sets information capable of identifying the start of the ending time (hereinafter referred to as the ending command) in the output buffer. When the ending time has elapsed, the main control CPU 40a ends the jackpot play.

Next, the game status processing performed by the main control CPU 40a will be described.
The main control CPU 40a sets the main base state flag to a value that can specify that control is to the first high base state for all types of jackpots, with the start of the ending time as a trigger. The main base state flag is a flag assigned to the main control RAM 40c, and is a flag that can specify whether control is to be to the low base state, the first high base state, or the second high base state.

The main control CPU 40a also identifies the game state when the jackpot lottery is won, the type of jackpot, and whether or not the game ball passed through the special passing area 36 during the jackpot game. The main control CPU 40a then identifies the upper limit number corresponding to the identified result as the first upper limit number that can be controlled to the first high base state, and sets the value that can identify the first upper limit number in the main high base number counter. The main high base number counter is assigned to the main control RAM 40c, and is a counter for counting the number of times that a special game that can be controlled to the high base state (first high base state or second high base state) is executed.

Specifically, when the main control CPU 40a determines that the game state when the jackpot lottery is won is a high base state, that the type of jackpot is a jackpot based on the Za pattern, and that the game ball has passed through the special passing area 36 during the jackpot game, it specifies "697" as the first upper limit number of times. When the main control CPU 40a determines that the game state when the jackpot lottery is won is a high base state, that the type of jackpot is a jackpot based on the Za pattern, and that the game ball has not passed through the special passing area 36 during the jackpot game, it specifies "597" as the first upper limit number of times. In all other cases, the main control CPU 40a specifies "100" as the first upper limit number of times.

When the main control CPU 40a determines that the game ball has passed through the special passing area 36 during a jackpot game, triggered by the input of an ending command, it sets the main probability state flag to a value that can specify whether to control to a high probability state for all types of jackpots. The main probability state flag is assigned to the main control RAM 40c, and is a flag that can specify whether to control to a low probability state or a high probability state. The main control CPU 40a then sets the specified number of times that can be controlled to a high probability state ("100" in this embodiment) to the main high probability count counter. The main high probability count counter is assigned to the main control RAM 40c, and is a counter for counting the number of times a special game that can be controlled to a high probability state is executed.

When the main control CPU 40a determines, as a result of input of an ending command, that the game ball has not passed through the special passing area 36 during jackpot play, it sets the main probability state flag to a value that can specify control to a low probability state for all types of jackpots. The main control CPU 40a then sets the main low probability count counter to a value that can specify the number of special games. The main low probability count counter is assigned to the main control RAM 40c, and is a counter for counting the number of times the special game is executed after control to the low probability state.

Then, each time a special game is executed, the main control CPU 40a subtracts "1" from the main high base count counter, the main high probability count counter, and the main low probability count counter that are assigned to the main control RAM 40c and that are not set to "0". In this embodiment, the main control CPU 40a subtracts "1" from each counter when the special game ends, but this is not limited to the above, and for example, each counter may be subtracted "1" when the special game starts.

In this way, in this embodiment, the first upper limit number of times is a different number of times when the jackpot lottery is won in a high base state and a jackpot based on the pattern Za is determined as the type of jackpot from other cases. Also, in this embodiment, the first upper limit number of times is a different number of times when the jackpot lottery is won in a high base state and a jackpot based on the pattern Za is determined as the type of jackpot, when the jackpot is controlled to a low probability state after the jackpot game ends and when the jackpot is controlled to a high probability state.

When the main high base count counter is updated from "1" to "0", the main control CPU 40a sets the main base state flag to a value that can specify that the game will be controlled to a low base state. When the main high probability count counter is updated from "1" to "0", the main control CPU 40a sets the main probability state flag to a value that can specify that the game will be controlled to a low probability state, and sets the main low probability count counter to a value that can specify the special count. In this way, when the main control CPU 40a controls the game to a high probability state after the end of a jackpot game, it controls the game to a low probability state when a predetermined control condition is met triggered by the execution of a specified number of special games. When the main low probability count counter is updated from "1" to "0", the main control CPU 40a sets the main base state flag to a value that can specify that the game will be controlled to a second high base state, and sets the main high base count counter to the second upper limit count.

In this embodiment, the main control CPU 40a, upon input of an opening command, sets the main base state flag, main probability state flag, main high base count counter, main high probability count counter, and main low probability count counter to "0," thereby initializing each flag and counter.

In this way, the main control CPU 40a may control to a low probability state after the end of a jackpot game, or may control to a high probability state after the end of a jackpot game. In particular, when the game ball passes through the special passing area 36 during a jackpot game, the main control CPU 40a controls to a high probability state after the end of a jackpot game, while when the game ball does not pass through the special passing area 36 during a jackpot game, the main control CPU 40a controls to a low probability state after the end of a jackpot game. When controlled to a high probability state after the end of a jackpot game, the main control CPU 40a can control to the high probability state until a specified number of special games are played without winning the jackpot lottery, and controls to the low probability state when a specified number of special games are played and a specified control condition is met.

In addition, when the main control CPU 40a controls the reel to the first high base state, it continues to control the reel to the first high base state until the first maximum number of special games are played without a jackpot being won, and then controls the reel to the low base state when the first maximum number of special games is played.

In detail, in this embodiment, when the main control CPU 40a has won a jackpot based on the pattern Za in the high base state and has controlled to the high probability state and the first high base state after the jackpot game ends, the main control CPU 40a controls to the low base state when 697 special games have been played without winning the jackpot lottery. When the main control CPU 40a has won a jackpot based on the pattern Za in the high base state and has controlled to the low probability state and the first high base state after the jackpot game ends, the main control CPU 40a controls to the low base state when 597 special games have been played without winning the jackpot lottery. On the other hand, when the main control CPU 40a has won a jackpot based on the patterns ZA, Zb, and Zc, or has won a jackpot based on the pattern Za in the low base state and has controlled to the first high base state, the main control CPU 40a controls to the low base state when 100 special games have been played without winning the jackpot lottery.

On the other hand, when the main control CPU 40a controls to the second high base state, it continues to control to the second high base state until the special game is played the second maximum number of times without winning a jackpot, and controls to the low base state when the special game is played the second maximum number of times. In other words, when controlling to the second high base state, the main control CPU 40a controls to the second high base state until the special game is played the second maximum number of times (759 times in this embodiment) without winning the jackpot lottery, regardless of the first maximum number of times controlled to the first high base state.

In addition, after the main control CPU 40a controls the reel to the low base state in response to the second maximum number of special games being played without a jackpot in the second high base state, the main control CPU 40a does not control the reel to the high base state in response to the special games being played a predetermined number of times in the low base state in response to the jackpot being not won.

In addition, when the main control CPU 40a is controlled to the first high base state after the end of the jackpot game, it controls the state to either the high probability state or the low probability state, while when the main control CPU 40a is controlled to the second high base state, it controls the state to the low probability state without controlling the state to the high probability state. In this embodiment, the main control CPU 40a that controls the game state corresponds to the game state control means.

When the main control CPU 40a sets the main probability state flag to a value that can identify control to a low probability state, it sets information that can identify a low probability state (hereinafter referred to as a low probability state command) in the output buffer. On the other hand, when the main control CPU 40a sets the main probability state flag to a value that can identify control to a high probability state, it sets information that can identify a high probability state (hereinafter referred to as a high probability state command) in the output buffer.

When the main control CPU 40a sets the main base state flag to a value that can identify control to the low base state, it sets information that can identify the low base state (hereinafter referred to as the low base state command) in the output buffer. On the other hand, when the main control CPU 40a sets the main base state flag to a value that can identify control to the first high base state, it sets information that can identify the first high base state (hereinafter referred to as the first high base state command) in the output buffer. Also, when the main control CPU 40a sets the main base state flag to a value that can identify control to the second high base state, it sets information that can identify the second high base state (hereinafter referred to as the second high base state command) in the output buffer.

Next, the normal symbol input process performed by the main control CPU 40a will be described. The normal symbol input process is performed as an interrupt process.
In the normal symbol input process, the main control CPU 40a judges whether the game ball has passed (entered) the gate 33 based on whether a detection signal has been input from the gate sensor SE4. If the game ball has not passed the gate 33, the main control CPU 40a ends the normal symbol input process. On the other hand, if the game ball has passed the gate 33, the main control CPU 40a judges whether the normal reserved number stored in the main control RAM 40c is less than the upper limit number ("4" in this embodiment). If the normal reserved number is not less than the upper limit number, the main control CPU 40a ends the normal symbol input process. If the normal reserved number is less than the upper limit number, the main control CPU 40a updates the normal reserved number stored in the main control RAM 40c by adding "1". This establishes the reservation condition for the normal game. The main control CPU 40a also controls the information display device 22 to display the updated normal reserved number.

Next, the main control CPU 40a acquires random numbers generated within the main control board 40, and stores random number information based on the acquired random numbers in the main control RAM 40c. For example, the random numbers are random numbers used in the lottery for selecting winning normal symbols, random numbers used to determine winning normal symbols, and random numbers used to determine the variable time of the normal game. In this case, the main control CPU 40a stores the random number information so that it is possible to identify that it is random number information for the normal game, and the storage order of the random number information. In this embodiment, by storing the random number information for the normal game in the main control RAM 40c, it is possible to suspend the execution of the normal game until the execution conditions for the normal game are met. Thereafter, the main control CPU 40a ends the normal symbol input process.

Next, the normal symbol start process performed by the main control CPU 40a will be described. The normal symbol start process is performed as an interrupt process.
In the normal symbol start process, the main control CPU 40a judges whether the execution conditions of the normal game are met. The main control CPU 40a judges positively when the normal win game is not being played and the normal game is not being played, while it judges negatively when the normal win game is being played or the normal game is being played. If the execution conditions of the normal game are not met, the main control CPU 40a ends the normal symbol start process.

On the other hand, if the conditions for executing the normal game are met, the main control CPU 40a judges whether the normal reserved number stored in the main control RAM 40c is "1" or more. If the normal reserved number is not "1" or more (if it is zero (0)), the main control CPU 40a ends the normal pattern start process. If the normal reserved number is "1" or more, the main control CPU 40a updates the normal reserved number stored in the main control RAM 40c by subtracting "1". In addition, the main control CPU 40a controls the information display device 22 so that the updated normal reserved number is displayed. Next, the main control CPU 40a reads out the random number information for the normal game that was stored first from the main control RAM 40c. In addition, when the main control CPU 40a reads out the random number information that was stored first, it erases the random number information from the main control RAM 40c.

Next, the main control CPU 40a determines whether or not a normal win will occur based on the read random number information, the current game state, and the normal win determination value stored in the main control ROM 40b.

In addition, in this embodiment, the main control CPU 40a wins a normal win with the same probability when the current game state is a low base state and when it is a high base state, and the normal win lottery can be said to be a lottery with the same probability of winning in the low base state, the first high base state, and the second high base state, but this is not limited to this. For example, the normal win lottery may be a lottery with a higher probability of winning in the high base state (first high base state and second high base state) than in the low base state. Also, for example, the normal win lottery may be a lottery with a higher probability of winning in the second high base state than in the first high base state, or a lottery with a higher probability of winning in the first high base state than in the second high base state. Any combination of these may be adopted.

When a normal win is won, the main control CPU 40a determines the normal winning symbol to be derived in the normal game and the fluctuation time of the normal game. When the main control CPU 40a determines the fluctuation time of the normal game, it sets information capable of identifying the determined fluctuation time (hereinafter referred to as the normal start command) in the output buffer. Note that the normal start command may be information capable of identifying the result of the lottery for the winning normal symbol. After that, the main control CPU 40a ends the normal symbol start process.

If the normal win is not achieved, the main control CPU 40a determines the normal losing symbol to be derived in the normal game and the fluctuation time of the normal game. When the main control CPU 40a determines the fluctuation time of the normal game, it sets a normal start command capable of identifying the determined fluctuation time in the output buffer. After that, the main control CPU 40a ends the normal symbol start process.

Then, the main control CPU 40a executes the normal game by performing a process separate from the normal symbol start process. Specifically, the main control CPU 40a starts the normal game and controls the information display device 22 so that the normal symbol determined in the normal symbol start process is derived when the variable time determined in the normal symbol start process has elapsed.

Next, the normal winning process performed by the main control CPU 40a will be described.
When a normal win is won, the main control CPU 40a determines the opening pattern of the second start hole 29 based on the current game state, and controls the normal actuator A1 so that the second start hole 29 is opened based on the determined opening pattern. In particular, when the above-mentioned opening time extension control is adopted, the main control CPU 40a determines the opening pattern for the low base in the low base state regardless of the normal winning symbol, and determines the opening pattern for the second high base in the second high base state. On the other hand, in the first high base state, the main control CPU 40a determines the opening pattern for the first high base corresponding to the determined normal winning symbol from among the multiple types of opening patterns for the first high base.

Next, various processes performed by the sub-control CPU 41a will be described.
First, the presentation game processing performed by the sub-control CPU 41a will be described.
The sub-control CPU 41a determines a symbol combination to be derived in the performance game based on the game start command and the symbol command. When the special symbol identifiable from the symbol command is a big win symbol, the sub-control CPU 41a determines a big win symbol combination by the performance symbol. When the special symbol identifiable from the symbol command is a losing symbol, the sub-control CPU 41a determines a losing symbol combination by the performance symbol.

When the conditions for executing a reach effect are met and a reach effect is to be executed in the effected game, the sub-control CPU 41a determines a losing symbol combination including a reach (for example, "787"). In this embodiment, the conditions for executing a reach effect are set to be that a losing variation pattern with a reach effect has been determined. Note that the conditions for executing a reach effect may also be set to be that the sub-control CPU 41a has performed a predetermined reach lottery and won the reach lottery.

The sub-control CPU 41a also controls the effect display device 27 to variably display the effect symbols in each column in response to the input of a game start command. That is, the sub-control CPU 41a starts the effect game. After starting the effect game, when a predetermined timing arrives, the sub-control CPU 41a temporarily stops and displays the symbol combination of the determined effect symbols, and in response to the input of a game end command, causes the symbol combination of the determined effect symbols to be derived. Note that the sub-control CPU 41a may measure a variation time that can be determined from the variation pattern, regardless of the game end command, and cause the symbol combination to be derived in response to the passage of the variation time. In this case, the game end command may be omitted.

Next, the big win presentation processing performed by the sub-control CPU 41a will be described.
The sub-control CPU 41a controls the performance display device 27 so that an opening performance is performed when an opening command is input. The sub-control CPU 41a controls the performance display device 27 so that a round performance is performed when a round command is input. Furthermore, the sub-control CPU 41a ends the round performance when a round end command is input. The sub-control CPU 41a controls the performance display device 27 so that an ending performance is performed when an ending command is input. In this way, the sub-control CPU 41a executes the opening performance, round performance, and ending performance as jackpot performances during jackpot play.

In this embodiment, the sub-control CPU 41a may control at least one of the decorative lamps 17 and the speakers 18 in addition to the performance display device 27 so that various performances are performed.

Next, the game status processing performed by the sub-control CPU 41a will be described.
When the sub-control CPU 41a inputs a low probability state command, it sets the sub-probability state flag to a value that can specify a low probability state, and sets the sub-low probability count counter to a value that can specify a special count. The sub-probability state flag is assigned to the sub-control RAM 41c, and is a flag that can specify whether to control to a low probability state or a high probability state. The sub-low probability count counter is assigned to the sub-control RAM 41c, and is a counter for counting the number of times a special game is executed after being controlled to a low probability state. On the other hand, when the sub-control CPU 41a inputs a high probability state command, it sets the sub-probability state flag to a value that can specify a high probability state, and sets the sub-high probability count counter to a value that can specify a specified count. The sub-high probability count counter is assigned to the sub-control RAM 41c, and is a counter for counting the number of times a special game that can be controlled to a high probability state is executed.

When the sub-control CPU 41a inputs a low base state command, it sets the sub-base state flag to a value that can identify the low base state. The sub-base state flag is assigned to the sub-control RAM 41c and is a flag that can identify whether to control to the low base state, the first high base state, or the second high base state. When the sub-control CPU 41a inputs a first high base state command, it sets the sub-base state flag to a value that can identify the first high base state, and sets the sub-high base count counter to a value that can identify the first upper limit count. The sub-high base count counter is a counter for counting the number of times a special game that can be controlled to a high base state (first high base state or second high base state) is executed. Specifically, the sub-control CPU 41a identifies the game state and the type of jackpot when the jackpot lottery is won, and identifies whether the game ball passed through the special passing area 36 during the jackpot game based on the input of the special passing command. Then, when the sub-control CPU 41a determines that the game state when the jackpot lottery is won is a high base state, that the type of jackpot is a jackpot based on the pattern Za, and that the game ball has passed through the special passing area 36 during the jackpot game, it determines "697" as the first upper limit number. When the sub-control CPU 41a determines that the game state when the jackpot lottery is won is a high base state, that the type of jackpot is a jackpot based on the pattern Za, and that the game ball has not passed through the special passing area 36 during the jackpot game, it determines "597" as the first upper limit number. In other cases, the sub-control CPU 41a determines "100" as the first upper limit number. When the sub-control CPU 41a inputs the second high base state command, it sets the sub-base state flag to a value that can identify the second high base state, and sets the high base count counter to a value that can identify the second upper limit number.

Here, the fluctuation pattern and the determination conditions for determining the fluctuation pattern will be described in detail with reference to FIG.
As shown in Fig. 7, there are several types of fluctuation patterns in this embodiment, and the fluctuation pattern is selected depending on whether or not it will be a jackpot. Specifically, the fluctuation patterns HP21, HP22, HP51 to HP54, and HP71 are defined as jackpot fluctuation patterns. The fluctuation patterns HP11, HP12, HP41, and HP61 are defined as miss reach fluctuation patterns, and the fluctuation patterns HP01 to HP03, HP31 to HP35, and HP61 are defined as miss fluctuation patterns.

As will be described in detail later, in this embodiment, fluctuation patterns HP01 to HP03, HP11, HP12, HP21, and HP22 are deviation fluctuation patterns that can be determined in a low base state. Fluctuation patterns HP31 to HP35, HP41, HP51 to HP54, HP61, and HP71 are deviation fluctuation patterns that can be determined in a low base state.

Each fluctuation pattern corresponds to a fluctuation time, and the fluctuation time can be determined from the fluctuation pattern. Specifically, in this embodiment, fluctuation patterns HP01 to HP03 are deviation fluctuation patterns that can be determined in a low base state. Fluctuation pattern HP02 is a fluctuation pattern that shortens the fluctuation time of fluctuation pattern HP01. Fluctuation pattern HP03 is a fluctuation pattern that further shortens the fluctuation time of fluctuation patterns HP01 and HP02. In this embodiment, fluctuation patterns HP31 to HP35 are deviation fluctuation patterns that can be determined in a high base state. Fluctuation patterns HP33 and HP34 are fluctuation patterns that shorten the fluctuation time of fluctuation patterns HP31 and HP32. Fluctuation pattern HP35 is a fluctuation pattern that further shortens the fluctuation time of fluctuation patterns HP31 to HP34. In this way, there are multiple types of deviation fluctuation patterns with different fluctuation times.

The variation patterns HP11 and HP21 are variation patterns in which a reach is formed in the presentation game (during the execution of the special game) and a normal reach (hereinafter, sometimes indicated as "NR") presentation is executed. The variation patterns HP12 and HP22 are variation patterns in which a reach is formed in the presentation game (during the execution of the special game) and a NR presentation is executed, and then a first super reach (hereinafter, sometimes indicated as "SR1") presentation is executed. The variation patterns HP41 and HP51 are variation patterns in which a reach is formed in the presentation game (during the execution of the special game) and a NR presentation is executed, and then a second super reach (hereinafter, sometimes indicated as "SR2") presentation is executed. The variation patterns HP52 to HP54 are jackpot variation patterns in which a reach is not formed in the presentation game (during the execution of the special game) and a jackpot occurs (indicated as "hit" in the figure). In particular, the fluctuation patterns HP11 and HP21 are fluctuation patterns that execute an NR effect and do not develop into an SR1 effect or an SR2 effect, and are fluctuation patterns with shorter fluctuation times than the fluctuation patterns HP12 and HP22.

The variation patterns HP61 and HP71 are variation patterns in which no reach is formed in the presentation game (during the execution of the special game) and a final presentation is executed that can be identified as the last special game controlled to the first high base state.

In this embodiment, multiple types of fluctuation pattern determination tables for determining a fluctuation pattern are stored in the main control ROM 40b. That is, in this embodiment, there are multiple types of fluctuation pattern determination tables. In this embodiment, the conditions for determining a fluctuation pattern by referring to the fluctuation pattern determination table correspond to the predetermined determination conditions. In this embodiment, this fluctuation pattern determination table is a table for determining a fluctuation pattern, but it does not have a data structure as a table, and may be a data group for determining a fluctuation pattern.

The multiple types of fluctuation pattern determination tables include fluctuation pattern determination tables T01, and T11 to T14. Any one of the multiple types of fluctuation pattern determination tables is referenced, and a fluctuation pattern is determined based on the referenced fluctuation pattern determination table. In this embodiment, the referenced fluctuation pattern determination table is determined based on the game state in which the jackpot lottery was won, the type of jackpot, the game state after the jackpot game ends, and the number of times the special game is executed. In this embodiment, the fluctuation pattern determination table T01 is a table referenced in a low base state, and the fluctuation pattern determination tables T11 to T14 are tables referenced in a high base state. In particular, the fluctuation pattern determination tables T11 to T13 are tables referenced in a first high base state, and the fluctuation pattern determination table T14 is a table referenced in a first high base state and a second high base state.

Specifically, the fluctuation pattern determination table T01 is a table capable of determining any one of the fluctuation patterns HP01 to HP03, HP11, HP12, HP21, and HP22 as the fluctuation pattern of the first special game. The fluctuation pattern determination table T01 is a table capable of determining any one of the fluctuation patterns HP03 and HP21 as the fluctuation pattern of the second special game. As will be described in detail later, the fluctuation pattern determination table T01 is a table that is referenced when the current game state is a low base state. In other words, the fluctuation pattern determination table T01 is a table in a low base state. In particular, the fluctuation pattern determination table T01 is a table from being controlled to the low base state to being controlled to the second high base state when a jackpot based on the symbol Za occurs in the low base state and the high base state, and after the jackpot game ends, the jackpot is controlled to the first high base state, then to the low base state, and then to the second high base state.

The fluctuation pattern determination table T11 is a table capable of determining either the fluctuation pattern HP35 or HP52 as the fluctuation pattern for the first special game. The fluctuation pattern determination table T11 is a table capable of determining either the fluctuation pattern HP31, HP33, HP41, or HP51 as the fluctuation pattern for the second special game. As will be described in detail later, the fluctuation pattern determination table T11 is a table that is referenced when a jackpot based on the ZA pattern is reached and the current game state is the first high base state after the jackpot game ends, except for the 100th special game.

The fluctuation pattern determination table T12 is a table capable of determining one of the fluctuation patterns HP32 and HP53 as the fluctuation pattern of the first special game. The fluctuation pattern determination table T12 is a table capable of determining one of the fluctuation patterns HP31, HP34, HP41, HP51, and HP54 as the fluctuation pattern of the second special game. As will be described in detail later, the fluctuation pattern determination table T12 is a table that is referenced when a jackpot based on the symbols Zb and Zc is reached and the current game state is the first high base state after the jackpot game ends, except for the 100th special game. The fluctuation pattern determination table T12 is a table that is referenced when a jackpot based on the symbol Za is reached in a low base state and the current game state is the first high base state after the jackpot game ends, except for the 100th special game.

The fluctuation pattern determination table T13 is a table that can determine either the fluctuation pattern HP61 or HP71 as the fluctuation pattern for the special game. As will be described in more detail later, the fluctuation pattern determination table T13 is a table that is referenced when a jackpot based on the patterns Zb and Zc occurs, and the current game state is the first high base state in the 100th special game after the jackpot game ends. The fluctuation pattern determination table T13 is a table that is referenced when a jackpot based on the pattern Za occurs in a low base state, and the current game state is the first high base state in the 100th special game after the jackpot game ends.

The fluctuation pattern determination table T14 is a table capable of determining either the fluctuation pattern HP35 or HP53 as the fluctuation pattern of the first special game. The fluctuation pattern determination table T14 is a table capable of determining either the fluctuation pattern HP35 or HP54 as the fluctuation pattern of the second special game. As will be described in detail later, the fluctuation pattern determination table T14 is a table that is referenced when a jackpot based on the symbol Za occurs in the high base state and the current game state is the first high base state after the jackpot game ends. The fluctuation pattern determination table T14 is a table that is referenced when the current game state is the second high base state. In this way, the fluctuation pattern determination table T14 is a table that may be referenced both when controlled to the first high base state and when controlled to the second high base state. In addition, in this embodiment, the fluctuation pattern determination table in the second high base state does not include the fluctuation pattern determination tables T01 and T11 to T13, but does include the fluctuation pattern determination table T14.

In this embodiment, the fluctuation pattern HP35 is a fluctuation pattern that can be determined by both the fluctuation pattern determination table T11 and the fluctuation pattern determination table T14. The fluctuation patterns HP53 and HP54 are fluctuation patterns that can be determined by both the fluctuation pattern determination table T12 and the fluctuation pattern determination table T14.

In addition, in this embodiment, the determination probability of the miss reach variation pattern is determined in the multiple types of variation pattern determination tables. In detail, the variation pattern determination table T01 is a table in which the determination probability of the miss reach variation pattern is determined when the first special game is executed is 23/241. The variation pattern determination table T11 is a table in which the determination probability of the miss reach variation pattern is determined when the second special game is executed is 9/241. The variation pattern determination table T12 is a table in which the determination probability of the miss reach variation pattern is determined when the second special game is executed is 6/241. In any other case, the miss reach variation pattern is not determined. In this way, the variation pattern determination tables T01, T11, and T12 are tables in which the miss reach variation pattern is determined (can be determined). On the other hand, the variation pattern determination tables T13 and T14 are tables in which the miss reach variation pattern is not determined (cannot be determined). The fluctuation pattern determination tables T01, T11, T12, and T14 are tables with different determination probabilities for determining a fluctuation pattern with reach effects when the jackpot lottery is not won. Also, the fluctuation pattern determination tables T11, T12, and T14 are tables with a lower determination probability for determining a fluctuation pattern with reach effects when the jackpot lottery is not won than the fluctuation pattern determination table T01. Also, the fluctuation pattern determination table T14 can be said to be a table in which a miss reach fluctuation pattern is more difficult to determine than the fluctuation pattern determination tables T01, T11, and T12.

Furthermore, the fluctuation pattern determination table T11 is a table in which one of the fluctuation patterns HP31, HP33, HP35, and HP41 is determined when the jackpot lottery is not won. The fluctuation pattern determination table T12 is a table in which one of the fluctuation patterns HP31, HP34, and HP41 is determined when the jackpot lottery is not won. And the fluctuation pattern determination table T14 is a table in which the fluctuation pattern HP35 is determined when the jackpot lottery is not won. In other words, the fluctuation pattern determination table T14 is a table in which the fluctuation pattern HP35 is determined with a higher probability than the fluctuation pattern determination tables T11 and T12 when the jackpot lottery is not won.

Furthermore, the fluctuation pattern determination table T11 is a table in which either the fluctuation pattern HP51 or HP52 is determined when the jackpot lottery is won. The fluctuation pattern determination table T12 is a table in which either the fluctuation pattern HP51, HP53, or HP54 is determined when the jackpot lottery is won. The fluctuation pattern determination table T14 is a table in which either the fluctuation pattern HP53 or HP54 is determined when the jackpot lottery is won. In other words, the fluctuation pattern determination table T14 is a table in which the fluctuation pattern HP53 or HP54 is determined with a higher probability than the fluctuation pattern determination tables T11 and T12 when the jackpot lottery is won.

In this embodiment, the fluctuation pattern HP31 corresponds to the first miss fluctuation pattern, and the fluctuation pattern HP35, which has a shorter fluctuation time than the fluctuation pattern HP31, corresponds to the second miss fluctuation pattern. In this embodiment, the fluctuation pattern HP51 corresponds to the first jackpot fluctuation pattern, and the fluctuation patterns HP53 and HP54, which have a shorter fluctuation time than the fluctuation pattern HP51, correspond to the second jackpot fluctuation pattern.

In this embodiment, the fluctuation pattern determination conditions that refer to the fluctuation pattern determination table T01 correspond to the normal determination conditions. In this embodiment, the fluctuation pattern determination conditions that refer to the fluctuation pattern determination table T11 correspond to the first specific determination conditions. In this embodiment, the fluctuation pattern determination conditions that refer to the fluctuation pattern determination table T12 correspond to the second special determination conditions. In this embodiment, the fluctuation pattern determination conditions that refer to the fluctuation pattern determination table T14 correspond to the first special determination conditions and the second specific determination conditions.

In this embodiment, the main control CPU 40a, upon the start of the ending time, specifies the game state when the jackpot lottery is won, the type of jackpot, and whether the game ball passed through the special passing area 36 during the jackpot game, and stores the specified items in the main control RAM 40c. The main control CPU 40a then sets information capable of specifying the determined first upper limit number in the fluctuation number counter. The fluctuation number counter is assigned to the main control RAM 40c, and is a counter for counting the number of times the special game is executed after the base state changes. Specifically, when the main control CPU 40a specifies that the game state when the jackpot lottery is won is a high base state, the type of jackpot is a jackpot based on the pattern Za, and the game ball has passed through the special passing area 36 during the jackpot game, it sets the fluctuation number counter to "697" as the first upper limit number. When the main control CPU 40a determines that the game state when the jackpot lottery is won is a high base state, that the type of jackpot is a jackpot based on the Za pattern, and that the game ball has not passed through the special passing area 36 during the jackpot game, it sets the first upper limit number of times to "597" in the variable count counter. In all other cases, the main control CPU 40a sets the first upper limit number of times to "100" in the variable count counter.

The main control CPU 40a subtracts "1" from the variation counter each time the special game is executed if the variation counter is not set to "0". In this embodiment, the main control CPU 40a subtracts "1" from each of the various counters when the special game ends, but this is not limited thereto, and for example, the main control CPU 40a may subtract "1" from each of the various counters when the special game starts.

When the main control CPU 40a determines the variation pattern in the special symbol start process, it refers to the variation pattern determination table based on the game state when the jackpot lottery was won, the type of jackpot, whether the game ball passed through the special passing area 36 during the jackpot game, the value set in the main base state flag, and the value set in the variation count counter.

In this embodiment, the presentation mode is controlled so that it can be changed after the end of each winning game or the start of a special game. The presentation mode corresponds to the type of background image and text image of the presentation display device 27, can be specified by the player from at least one of the background image and text image, and is an image that is displayed regardless of the type of variation pattern. The presentation mode can be executed across multiple consecutive special games.

As shown in Fig. 8, there are a plurality of types of presentation modes in this embodiment. The plurality of types of presentation modes are roughly divided into four types, presentation modes MA to MD.
Presentation mode MA is a presentation mode when in a low base state, and presentation modes MB to MD are presentation modes when in a high base state. In particular, in this embodiment, presentation modes MB and MC are presentation modes when in the first high base state, and presentation mode MD is a presentation mode when in the first high base state and the second high base state. Also, in this embodiment, presentation mode MA is a presentation mode that can be controlled only when in a low probability state, and is not controlled when in a high probability state. Presentation modes MB to MD are presentation modes that can be controlled in both a high probability state and a low probability state, and are presentation modes that may be controlled when in a high probability state.

As shown in FIG. 9, when it is controlled to a low base state, it is controlled to presentation mode MA. On the other hand, when it is controlled to a high base state, it is controlled to one of presentation modes MB to MD. In particular, in this embodiment, when it is controlled to a first high base state, it is controlled to one of presentation modes MB to MD, and when it is controlled to a second high base state, it is controlled to presentation mode MD.

Regardless of whether the machine is controlled to a low base state or a high base state, if a jackpot based on the pattern ZA is obtained, the machine will transition to presentation mode MB after the jackpot game ends. Regardless of whether the machine is controlled to a low base state or a high base state, if a jackpot based on the pattern Zb or Zc is obtained, the machine will transition to presentation mode MC after the jackpot game ends. If a jackpot based on the pattern Za is obtained when the machine is controlled to a low base state, the machine will transition to presentation mode MC after the jackpot game ends. If a jackpot based on the pattern Za is obtained when the machine is controlled to a high base state, the machine will transition to presentation mode MD after the jackpot game ends. After being controlled to a low probability state, a special number of special games are played, the low base state ends, and the machine will transition to presentation mode MD when it is controlled to a second high base state. In this way, presentation mode MD can be said to be a presentation mode that can be used both when a jackpot based on the Za pattern occurs when the game is controlled to a high base state, and when a special game is played a special number of times after the game is controlled to a low probability state.

When controlled to the high base state, the end condition of the high base state is met and the device is controlled to the low base state, the device transitions to presentation mode MA. In this embodiment, when controlled to the first high base state after the end of a jackpot game, the device is controlled to one of presentation modes MB to MD, but when controlled to the low base state after the end of a jackpot game, the first high base state ends in the first maximum number of special games, the device transitions to presentation mode MA. Also, when controlled to the second high base state, the device is controlled to the second high base state, and then the second maximum number of special games is played, the second high base state ends, and the device transitions to presentation mode MA when controlled to the low base state.

Next, the control regarding the presentation mode executed by the sub-control CPU 41a will be described.
When the sub-control CPU 41a determines that the power supply is turned on and that the device is in a low base state based on the control information from the main control CPU 40a, the sub-control CPU 41a sets the presentation mode flag to information indicating the presentation mode MA. The presentation mode flag is assigned to the sub-control RAM 41c and is a flag indicating the presentation mode to be held.

When the sub-control CPU 41a is powered on and determines that the first high base state is present based on the control information from the main control CPU 40a, it sets the presentation mode flag to information indicating the presentation mode MB. The sub-control CPU 41a determines the game state when the jackpot lottery is won, the type of jackpot, and whether the game ball passed through the special passing area 36 during the jackpot game, triggered by the input of an ending command, and sets the presentation mode flag to information indicating the presentation mode. In this embodiment, when the sub-control CPU 41a determines that the jackpot is based on the pattern ZA, it sets the presentation mode flag to information indicating the presentation mode MB. When the sub-control CPU 41a determines that the jackpot is based on the pattern Za in the high base state, it sets the presentation mode flag to information indicating the presentation mode MD. When the sub-control CPU 41a determines that the jackpot is otherwise, it sets the presentation mode flag to information indicating the presentation mode MC. When the power is turned on and the sub-control CPU 41a determines that the second high base state is present based on the control information from the main control CPU 40a, it sets the presentation mode flag to information indicating the presentation mode MD. In addition, the sub-control CPU 41a sets the presentation mode flag to information indicating the presentation mode MA in response to the input of a low base state command in the high base state.

Then, the sub-control CPU 41a causes the performance display device 27 to display a background image of a type corresponding to the value set in the performance mode flag.
In this way, the presentation mode MA is a presentation mode that can be continuously controlled in at least a plurality of consecutive special games among the special games from the start to the end of the control to the low base state. When a jackpot based on the symbol Za occurs, and after the end of the jackpot game, the game is controlled to the first high base state, then the low base state, and then the second high base state, the presentation mode MA is a presentation mode that is controlled at least in any of the periods from the control to the low base state to the control to the second high base state.

In addition, presentation mode MB is a presentation mode that is entered (controlled) when a jackpot based on pattern ZA occurs and control is exercised to the first high base state after the jackpot game ends. In addition, presentation mode MC is a presentation mode that is entered (controlled) when a jackpot based on pattern Za occurs in the low base state and control is exercised to the first high base state after the jackpot game ends, and can be continuously controlled in at least multiple consecutive special games among the special games from the start to the end of control to the first high base state.

Presentation mode MD is a presentation mode that is transitioned to (controlled) when a jackpot based on pattern Za occurs in the high base state and control is exercised to the first high base state after the jackpot play ends, and is a presentation mode that can be continuously controlled thereafter for at least multiple consecutive special games among the special games from the start to the end of control to the first high base state.

The presentation mode MD is a presentation mode that is transitioned to (controlled) when control is made from the low base state to the second high base state, and can be continuously controlled thereafter in at least a number of consecutive special games among the special games from the start to the end of control to the second high base state.

In this embodiment, the sub-control CPU 41a that controls the presentation mode corresponds to the presentation mode control means. In this embodiment, presentation mode MA corresponds to the normal presentation mode, presentation mode MB corresponds to the first specific presentation mode, presentation mode MC corresponds to the second special presentation mode, and presentation mode MD corresponds to the first special presentation mode and the second specific presentation mode.

Here, the game state, the conditions for determining the variation pattern, and the presentation mode will be described in detail with reference to FIG.
As shown in FIG. 10(a), when the game is controlled to the high probability state and the first high base state after the end of a jackpot game, the type of variation pattern determination table referenced in accordance with the number of times the special game is executed and the presentation mode controlled differ depending on the base state when the jackpot lottery is won and the type of jackpot.

Specifically, if a jackpot is hit based on the pattern ZA and the state is controlled to the high probability state and the first high base state after the jackpot game ends, the 1st to 100th special games are controlled to the high probability state and the first high base state after the jackpot game ends. After the jackpot game ends, the variation pattern determination table T11 is referenced for the 1st to 99th special games, and the variation pattern determination table T13 is referenced for the 100th special game. After the jackpot game ends, the 1st to 100th special games are controlled to the presentation mode MB. Then, when the 100th special game ends after the jackpot game ends, the state is controlled to the low probability state and the low base state.

After the jackpot game ends, the 101st to 698th special games are controlled to a low probability state and a low base state. After the jackpot game ends, the 101st to 698th special games are controlled to a low probability state and a low base state by referring to the variation pattern determination table T01 and being controlled to the presentation mode MA. Then, when the 698th special game is completed after the jackpot game ends, the game is controlled to a low probability state and a second high base state.

After the jackpot game ends, in the 699th to 1458th special games, the game is controlled to a low probability state and a second high base state. After the jackpot game ends, in the 699th to 1458th special games, the variation pattern determination table T14 is referenced and the game is controlled to the presentation mode MD. Then, when the 1458th special game ends after the jackpot game ends, the game is controlled to a low probability state and a low base state.

After the jackpot game ends, the special game from the 1459th time onwards is controlled to a low probability state and low base state. After the jackpot game ends, the special game from the 1459th time onwards is controlled to the presentation mode MA by referring to the variation pattern determination table T01.

Next, if a jackpot is generated based on the symbols Zb and Zc, and the state is controlled to the high probability state and the first high base state after the jackpot game ends, the 1st to 100th special games are controlled to the high probability state and the first high base state after the jackpot game ends. After the jackpot game ends, the variation pattern determination table T12 is referenced in the 1st to 99th special games, and the variation pattern determination table T13 is referenced in the 100th special game. After the jackpot game ends, the 1st to 100th special games are controlled to the presentation mode MC. Then, when the 100th special game ends after the jackpot game ends, the state is controlled to the low probability state and the low base state. In this case, the 101st and subsequent special games after the jackpot game end will be jackpots based on the symbols ZA, and the explanation will be omitted because it is the same as the case where the state is controlled to the high probability state and the first high base state after the jackpot game ends.

In addition, if a jackpot based on the Za symbol occurs in the low base state, and control is exercised to the high probability state and the first high base state after the jackpot game ends, this is the same as when a jackpot based on the Zb and Zc symbol occurs in all special games after the jackpot game ends, and control is exercised to the high probability state and the first high base state after the jackpot game ends, so an explanation will be omitted.

Next, if a jackpot based on the symbol Za occurs in the high base state, and control is made to the high probability state and the first high base state after the jackpot game ends, control is made to the high probability state and the first high base state in the 1st to 100th special games after the jackpot game ends. After the jackpot game ends, control is made to the low probability state and the first high base state in the 1st to 100th special games, with reference to the variation pattern determination table T14. Then, when the 100th special game ends after the jackpot game ends, control is made to the low probability state and the first high base state.

After the jackpot game ends, the 101st to 697th special games are controlled to a low probability state and a first high base state. After the jackpot game ends, the 101st to 697th special games are controlled to a low probability state and a first high base state by referring to the variation pattern determination table T14 and being controlled to the presentation mode MD. Then, when the 697th special game is completed after the jackpot game ends, the game is controlled to a low probability state and a low base state.

After the jackpot game ends, in the 698th special game, the game is controlled to a low probability state and a low base state. After the jackpot game ends, in the 698th special game, the variation pattern determination table T01 is referenced and the game is controlled to presentation mode MA. Then, when the 698th special game ends after the jackpot game ends, the game is controlled to a low probability state and a second high base state. In this case, in the 699th and subsequent special games after the jackpot game end, the game is the same as in the other cases, so a description will be omitted.

In particular, in this embodiment, after the end of a jackpot game, the first 697th special game is controlled to the first high base state, so there is a high possibility that the execution of the second special game will be put on hold. In addition, the fluctuation pattern determination table T01 is a table that determines a fluctuation pattern for the second special game with a shorter fluctuation time than the fluctuation pattern for the first special game. Therefore, after the end of a jackpot game, the 698th special game is controlled to the low base state, but there is a high possibility that the second special game with a short fluctuation time will be executed, allowing the game to progress smoothly and increasing interest in the game.

As shown in FIG. 10(b), when the game is controlled to the low probability state and the first high base state after the end of the jackpot game, the type of variation pattern determination table referenced in response to the number of times the special game is executed and the presentation mode controlled differ depending on the base state when the jackpot lottery is won and the type of jackpot.

Specifically, if a jackpot is hit based on the symbol ZA, and the game is controlled to the low probability state and the first high base state after the jackpot game ends, the game is controlled to the low probability state and the first high base state in the 1st to 100th special games after the jackpot game ends. After the jackpot game ends, the variation pattern determination table T11 is referenced in the 1st to 99th special games, and the variation pattern determination table T13 is referenced in the 100th special game. After the jackpot game ends, the game is controlled to the presentation mode MB in the 1st to 100th special games. Then, when the 100th special game ends after the jackpot game ends, the game is controlled to the low probability state and the low base state.

After the jackpot game ends, the 101st to 598th special games are controlled to a low probability state and low base state. After the jackpot game ends, the 101st to 598th special games are controlled to a low probability state and low base state by referring to the variation pattern determination table T01 and being controlled to presentation mode MA. Then, when the 598th special game is completed after the jackpot game ends, the game is controlled to a low probability state and second high base state.

After the jackpot game ends, the 599th to 1358th special games are controlled to a low probability state and a second high base state. After the jackpot game ends, the 599th to 1358th special games are controlled to a low probability state and a second high base state by referring to the variation pattern determination table T14 and controlling to the presentation mode MD. Then, when the 1358th special game is completed after the jackpot game ends, the game is controlled to a low probability state and a low base state.

After the jackpot game ends, the 1359th and subsequent special games are controlled to a low probability state and low base state. After the jackpot game ends, the 1359th and subsequent special games are controlled to the MA presentation mode by referring to the variation pattern determination table T01.

Next, if a jackpot is generated based on the symbols Zb and Zc, and the state is controlled to the low probability state and the first high base state after the jackpot game ends, the 1st to 100th special games are controlled to the low probability state and the first high base state after the jackpot game ends. After the jackpot game ends, the variation pattern determination table T12 is referenced in the 1st to 99th special games, and the variation pattern determination table T13 is referenced in the 100th special game. After the jackpot game ends, the 1st to 100th special games are controlled to the presentation mode MC. Then, when the 100th special game ends after the jackpot game ends, the state is controlled to the low probability state and the low base state. In this case, the 101st and subsequent special games after the jackpot game end will be jackpots based on the symbols ZA, and the explanation will be omitted because it is the same as the case where the state is controlled to the low probability state and the first high base state after the jackpot game ends.

In addition, if a jackpot based on the Za symbol occurs in the low base state, and control is exercised to the low probability state and the first high base state after the jackpot game ends, this is the same as when a jackpot based on the Zb and Zc symbol occurs in all special games after the jackpot game ends, and control is exercised to the low probability state and the first high base state after the jackpot game ends, so an explanation will be omitted.

Next, if a jackpot based on the symbol Za occurs in the high base state, and control is made to the low probability state and the first high base state after the jackpot game ends, control is made to the low probability state and the first high base state in the 1st to 100th special games after the jackpot game ends. After the jackpot game ends, in the 1st to 100th special games, the variation pattern determination table T14 is referenced, and control is made to the presentation mode MD. Then, when the 100th special game ends after the jackpot game ends, control is made to the low probability state and the first high base state.

After the jackpot game ends, the 101st to 597th special games are controlled to a low probability state and a first high base state. After the jackpot game ends, the 101st to 597th special games are controlled to a low probability state and a first high base state by referring to the variation pattern determination table T14 and being controlled to the presentation mode MD. Then, when the 597th special game is completed after the jackpot game ends, the game is controlled to a low probability state and a low base state.

After the jackpot game ends, in the 598th special game, the game is controlled to a low probability state and a low base state. After the jackpot game ends, in the 598th special game, the variation pattern determination table T01 is referenced and the game is controlled to presentation mode MA. Then, when the 598th special game ends after the jackpot game ends, the game is controlled to a low probability state and a second high base state. In this case, in the 599th and subsequent special games after the jackpot game end, the game is the same as in the other cases, so a description will be omitted.

In this embodiment, various effects can be executed by the effect display device 27. The various effects include a break-in effect and a final effect.
In this embodiment, the entry performance is an performance executed when controlled to a high base state. The entry performance is a performance in which an introduction performance, a mode notification performance, and a first right hit notification performance are executed in sequence. The introduction performance is, for example, a performance in which a castle gate closes, and is a performance in which it is possible to identify that the execution of the entry performance has begun. The mode notification performance is a performance in which the performance mode to be controlled is identified, and is a performance in which a text image and a background image corresponding to the performance mode to be controlled are displayed. The first right hit notification performance is a notification performance in which it is possible to identify that the game ball will flow down to the right side of the game area 21 during the execution of the entry performance.

In addition, in this embodiment, there are a first entry performance and a second entry performance. The first entry performance is a performance that is executed when controlled to the first high base state, and is a performance that can be identified as being controlled to the high base state. On the other hand, the second entry performance is a performance that is executed when controlled to the second high base state, and is a performance that can be identified as being controlled to the high base state.

In this embodiment, the final effect is an effect that is executed during the execution of the last special game controlled to the first high base state, and is an effect that is executed when the variation patterns HP61 and HP71 are determined.

The final performance control process executed by the sub-control CPU 41a will be described below. The final performance control process is called at predetermined intervals.
The sub-control CPU 41a controls the effect display device 27 to execute the final effect when the variation pattern designated by the game start command is the variation pattern HP61 or HP71, and ends the final effect control process. In this way, the effect display device 27 executes the final effect when the variation pattern HP61 or HP71 is determined. In other words, the final effect is an effect executed during the 100th special game after the end of the jackpot game when a jackpot based on the patterns ZA, Zb, or Zc is obtained, or when a jackpot based on the pattern Za is obtained in a low base state, and is an effect that is not executed after the end of the jackpot game when a jackpot based on the pattern Za is obtained in a high base state.

Next, the first entry performance control process executed by the sub-control CPU 41a will be described. The first entry performance control process is a process that is called at a predetermined cycle.
The sub-control CPU 41a executes control to execute the first entry performance in response to the input of the ending command, and ends the first entry performance control process. As a result, when the performance display device 27 is controlled to the first high base state after the end of the jackpot game, it executes the first entry performance that can specify that the high base state is controlled from the timing during the jackpot game.

Next, the second entry performance control process executed by the sub-control CPU 41a will be described. The second entry performance control process is a process that is called at a predetermined cycle.
The sub-control CPU 41a judges whether the second high base state command has been input. If it is judged that the second high base state command has been input, the sub-control CPU 41a executes a second entry performance start process to start the execution of the second entry performance, and ends the second entry performance control process. Thus, in this embodiment, the second entry performance is executed when the game is controlled to the second high base state after the end of the jackpot game, both when a jackpot based on the pattern Za occurs in the high base state and when it does not occur.

As described above in detail, this embodiment has the following advantages.
(1) When a jackpot based on the symbol Za occurs in the low base state and the game is controlled to the first high base state after the jackpot game ends, the number of times the special game is executed from the low base state to the second high base state is smaller when a jackpot based on the symbol Za occurs in the high base state and the game is controlled to the first high base state after the jackpot game ends than when a jackpot based on the symbol Za occurs in the high base state and the game is controlled to the first high base state after the jackpot game ends. Therefore, it is possible to heighten the expectation of being controlled to the second high base state, and to make the player pay attention to whether the game is controlled to the high base state or the low base state when the jackpot occurs, thereby improving the interest in the game.

(2) In the high base state, a jackpot based on the pattern Za is reached, and after the jackpot game is completed, the machine is controlled to the first high base state, and then 597 or 697 special games are played without winning the jackpot lottery. In the low base state, a jackpot based on the pattern Za is reached, and after the jackpot game is completed, the machine is controlled to the first high base state, and then 100 special games are played without winning the jackpot lottery. 597 or 697 is more than 100, and the special number, which is the number of times the special game is played from when the machine is controlled to the low probability state until when the machine is controlled to the second high base state, is greater than 597. Therefore, when a jackpot based on the symbol Za occurs in the high base state, and when the jackpot game is completed and the game is controlled to the first high base state, a jackpot based on the symbol Za occurs in the low base state, and when the jackpot game is completed and the game is controlled to the first high base state, the game can be controlled to the first high base state with a larger number of special games than when the game is controlled to the first high base state. Therefore, in order to specify the number of special games controlled to the first high base state, when the jackpot lottery is won, attention can be drawn to whether the game is controlled to the high base state or the low base state, which can increase interest in the game.

(3) In addition, the number of times the special game is executed between being controlled to the low base state and being controlled to the second high base state differs when a jackpot based on the ZA pattern is reached and control is made to the first high base state after the jackpot game ends, and when a jackpot based on the Za pattern is reached in the high base state and control is made to the first high base state after the jackpot game ends. This can heighten the anticipation of being controlled to the second high base state, and can draw attention to whether the type of jackpot is a jackpot based on the ZA pattern or a jackpot based on the Za pattern, thereby increasing interest in the game.

(4) In particular, the second special game is a special game that is more advantageous to the player than the first special game. The number of times that the special game is executed from being controlled to the low base state until being controlled to the second high base state is smaller when the pattern Za is obtained in the high base state and the reel is controlled to the first high base state after the end of the jackpot game than when a jackpot is obtained based on the pattern ZA and the reel is controlled to the first high base state after the end of the jackpot game. Therefore, a bonus can be given to the player for winning the jackpot lottery in the second special game, which is more advantageous to the player than the first special game, and interest in the game can be increased.

(5) When a jackpot based on the pattern ZA is obtained, the system is controlled to the first high base state after the jackpot game ends, and then 100 special games are played without winning the jackpot lottery, the system is controlled to the low base state. On the other hand, when a jackpot based on the pattern Za is obtained in the high base state, the system is controlled to the first high base state after the jackpot game ends, and then 597 or 697 special games are played without winning the jackpot lottery, the system is controlled to the low base state. 597 times is greater than 100 times, and 599 times from being controlled to the low probability state to being controlled to the second high base state is greater than 597 times. Therefore, when a jackpot based on the pattern Za is obtained in the high base state, and the system is controlled to the first high base state after the jackpot game ends, the system is controlled to the first high base state with a greater number of special games than when the system is controlled to the first high base state after the jackpot game ends. Therefore, in order to determine the number of special games controlled to the first high base state, it is possible to draw attention to whether the type of jackpot is based on the ZA pattern or the Za pattern, thereby increasing interest in the game.

(6) Furthermore, when a jackpot is hit based on the pattern Za and the jackpot game is ended and the player is controlled to the first high base state, even if the player is controlled to the low probability state after the jackpot game is ended, the player is controlled from the first high base state to the low base state and then to the second high base state. Similarly, even if the player is controlled to the high probability state after the jackpot game is ended and then to the low probability state after the jackpot game is ended, the player is controlled from the first high base state to the low base state and then to the second high base state. Therefore, when a jackpot is hit based on the pattern Za and the player is controlled to the first high base state after the jackpot game is ended, even if the player is controlled to the high probability state after the jackpot game is ended and then to the low probability state, the player is controlled from the first high base state to the low base state and then to the second high base state, which can heighten the expectation of being controlled to the second high base state, and can increase the interest in the game.

(7) After the jackpot game ends, the high probability state can be controlled until 100 special games are played, and the 100 times that can be controlled to the high probability state are smaller than the 597 and 697 times that can be controlled to the first high base state. Therefore, when a jackpot based on the pattern Za occurs in the high base state and the high probability state and the first high base state are controlled after the jackpot game ends, it is possible to heighten the expectation of continuing to be controlled to the first high base state even after being controlled from the high probability state to the low probability state, and to increase interest in the game.

(8) When controlled to the second high base state, the player is controlled to the second high base state until 759 special games are played without winning the jackpot lottery. The number of times that the player is controlled to the second high base state is greater than the number of special games, 579 and 679, played from the time the player is controlled to the low probability state until the player is controlled to the second high base state. As a result, the number of times that the special game is played when the player is controlled to the second high base state is greater than the number of times that the special game is played from the time the player is controlled to the low probability state until the player is controlled to the second high base state, which can heighten expectations for being controlled to the second high base state and increase interest in the game.

(9) When a jackpot based on the symbol Za occurs in the high base state, and after the jackpot game ends, the reel is controlled to the first high base state, and then controlled to the low base state, the number of times the special game is executed from the time of control to the low base state until the time of control to the second high base state is less than 597 times. This can heighten the sense of anticipation for being controlled from the low base state to the second high base state, and can increase interest in the game.

(10) When a jackpot based on pattern Za occurs in the high base state, and after the jackpot game ends, the reel is controlled to the first high base state, and then controlled to the low base state, the number of times special games are executed from when the reel is controlled to the low base state until when the reel is controlled to the second high base state is smaller than the reserved upper limit number. Therefore, if the reserved number of special games reaches the reserved upper limit number before the reel is controlled from the first high base state to the low base state, the reel will be controlled to the second high base state at least after the reserved upper limit number of special games has been executed. Therefore, it is possible to heighten the sense of anticipation for being controlled from the low base state to the second high base state, and to increase interest in the game.

(11) The number of times (597 times) that the special game can be executed while being continuously controlled in the low probability state and the first high base state is greater than the reciprocal of the probability of winning the jackpot lottery in the low probability state. Therefore, even if the game is continuously controlled in the low probability state and the high base state until 597 special games are executed without a jackpot being won after the end of a jackpot game, it is possible to increase the possibility of winning the jackpot lottery, heighten the anticipation of winning the jackpot lottery, and increase interest in the game.

(12) The second upper limit number of times is a number greater than the reciprocal of the probability of winning the jackpot lottery in the low probability state. Therefore, even if the state is controlled to the second high base state and low probability state until the special game of the second upper limit number of times is played, the possibility of winning the jackpot lottery by the time the special game of the second upper limit number of times is played can be increased, the anticipation of winning the jackpot lottery can be heightened, and interest in the game can be improved.

(13) The fluctuation pattern determination table T14 is a table in the first high base state in which a jackpot based on the pattern Za occurs in the high base state and control is performed after the jackpot game ends. The fluctuation pattern determination table T12 is a table in the first high base state in which a jackpot based on the pattern Za occurs in the low base state and control is performed after the jackpot game ends. The fluctuation pattern determination table in the second high base state does not have the fluctuation pattern determination table T12, but does have the fluctuation pattern determination table T14. Therefore, the fluctuation pattern can be determined based on the fluctuation pattern determination table T14 in the same way when a jackpot based on the pattern Za occurs in the high base state and control is performed to the first high base state after the jackpot game ends and when control is performed to the second high base state. Therefore, the fluctuation pattern determination table can be made common, the presentation effect can be enhanced, and interest in the game can be increased.

(14) The variation pattern can be determined so that it is different when a jackpot based on the pattern Za occurs in the high base state, and when the jackpot game is completed and the reel is controlled to the first high base state and the second high base state, and when a jackpot based on the pattern Za occurs in the low base state and when the jackpot game is completed and the reel is controlled to the first high base state. Therefore, the presentation effect can be enhanced, and interest in the game can be increased.

(15) When the jackpot lottery is not won, the fluctuation pattern determination table T14 is a table that determines a fluctuation pattern HP35, which has a shorter fluctuation time than the fluctuation pattern HP31, with a higher probability than the fluctuation pattern determination table T12. For this reason, when a jackpot based on the pattern Za occurs in the high base state and the reel is controlled to the first high base state or the second high base state after the jackpot game ends, the fluctuation time of the special game is more likely to be shorter than when a jackpot based on the pattern Za occurs in the low base state and the reel is controlled to the first high base state after the jackpot game ends. Therefore, the special game can be played smoothly, and interest in the game can be increased.

(16) When a jackpot lottery is won, the fluctuation pattern determination table T14 is a table that determines fluctuation patterns HP53, HP54, which have a shorter fluctuation time than the fluctuation pattern HP51, with a higher probability than the fluctuation pattern determination table T12. For this reason, when a jackpot based on the pattern Za occurs in the high base state, and when the machine is controlled to the first high base state or the second high base state after the jackpot game ends, the fluctuation time of the special game is more likely to be shorter than when a jackpot based on the pattern Za occurs in the low base state, and when the machine is controlled to the first high base state after the jackpot game ends. Therefore, the special game can be played smoothly, and interest in the game can be increased.

(17) The fluctuation pattern determination table T14 is a table in the first high base state in which a jackpot based on the pattern Za occurs in the high base state and control is performed after the jackpot game ends. The fluctuation pattern determination table T11 is a table in the first high base state in which a jackpot based on the pattern ZA occurs and control is performed after the jackpot game ends. The fluctuation pattern determination table in the second high base state does not have the fluctuation pattern determination table T11, but does have the fluctuation pattern determination table T14. Therefore, it is possible to determine a fluctuation pattern differently between when a jackpot based on the pattern Za occurs in the high base state and when the game is controlled to the first high base state and when the game is controlled to the second high base state after the jackpot game ends, and when a jackpot based on the pattern ZA occurs and when the game is controlled to the first high base state after the jackpot game ends. Therefore, the presentation effect can be enhanced, and interest in the game can be increased.

(18) When the jackpot lottery is not won, the fluctuation pattern determination table T14 is a table that determines a fluctuation pattern HP35, which has a shorter fluctuation time than the fluctuation pattern HP31, with a higher probability than the fluctuation pattern determination table T11. For this reason, when a jackpot occurs based on the pattern Za in the high base state, and when the reel is controlled to the first high base state after the jackpot game ends and when the reel is controlled to the second high base state, the fluctuation time of the special game is more likely to be shorter than when a jackpot occurs based on the pattern ZA and the reel is controlled to the first high base state after the jackpot game ends. Therefore, the special game can be played smoothly, and interest in the game can be increased.

(19) When a jackpot lottery is won, the fluctuation pattern determination table T14 is a table that determines fluctuation patterns HP53, HP54, which have a shorter fluctuation time than the fluctuation pattern HP51, with a higher probability than the fluctuation pattern determination table T11. For this reason, when a jackpot occurs based on the pattern Za in the high base state, and when the machine is controlled to the first high base state or the second high base state after the jackpot game ends, the fluctuation time of the special game is more likely to be shorter than when a jackpot occurs based on the pattern ZA and the machine is controlled to the first high base state after the jackpot game ends. Therefore, the special game can be played smoothly, and interest in the game can be increased.

(20) The fluctuation pattern determination table T01 is a table from when a jackpot based on the pattern Za occurs in the high base state, and when the jackpot game is ended and then controlled to the first high base state and then controlled to the low base state, until when it is controlled to the second high base state. Therefore, the fluctuation pattern determination table T01 is a table when a jackpot based on the pattern Za occurs, and when the jackpot game is ended and then controlled to the first high base state and then controlled to the low base state, regardless of the base state when the jackpot lottery is won. And when a jackpot based on the pattern Za occurs in the high base state and when a jackpot based on the pattern Za occurs in the low base state, the fluctuation pattern can be determined based on the fluctuation pattern determination table T01 in the low base state. Therefore, the fluctuation pattern determination table can be made common, the presentation effect can be enhanced, and interest in the game can be increased.

(21) In addition, the probability of determining a miss reach fluctuation pattern is different between the fluctuation pattern determination table T12 and the fluctuation pattern determination table T14. Therefore, when a jackpot based on the pattern Za occurs in the high base state, and the jackpot lottery is not won, the miss reach fluctuation pattern can be determined with the same determination probability when the jackpot game is controlled to the first high base state and when the jackpot game is controlled to the second high base state after the jackpot game ends. Therefore, the determination conditions can be standardized, the presentation effect can be enhanced, and interest in the game can be increased.

(22) In addition, when a jackpot based on the pattern Za occurs in a high base state and control is made to the first high base state after the jackpot game ends, a miss reach fluctuation pattern can be determined with a different determination probability when a jackpot based on the pattern Za occurs in a low base state and control is made to the first high base state after the jackpot game ends. This can therefore enhance the presentation effect and increase interest in the game.

(23) The fluctuation pattern determination table T12 is a table in which a miss reach fluctuation pattern can be determined, and the fluctuation pattern determination table T14 has a lower determination probability for a miss reach fluctuation pattern to be determined than the fluctuation pattern determination table T12, and is a determination condition in which a miss reach fluctuation pattern is not determined. Therefore, in a high base state, a jackpot based on the pattern Za occurs, and when the system is controlled to the first high base state and the second high base state after the jackpot game ends, a jackpot based on the pattern Za occurs in a low base state, and a miss reach fluctuation pattern is more difficult to determine than when the system is controlled to the first high base state after the jackpot game ends. Therefore, the special game can be played smoothly, and interest in the game can be increased.

(24) The fluctuation pattern determination tables T12 and T14 have determination conditions with a lower probability of determining a miss reach effect fluctuation pattern than the fluctuation pattern determination table T01. Therefore, when controlled to a high base state, it is more difficult to determine a miss reach fluctuation pattern than when controlled to a low base state, allowing the execution of the special game to proceed smoothly and increasing interest in the game.

(25) The fluctuation pattern determination table T11 and the fluctuation pattern determination table T14 have different determination probabilities for determining a miss reach fluctuation pattern. Therefore, a miss reach fluctuation pattern can be determined with different determination probabilities when a jackpot based on the pattern Za occurs in the high base state and control is made to the first high base state after the jackpot game ends, and when a jackpot based on the pattern ZA occurs and control is made to the first high base state after the jackpot game ends. Therefore, the presentation effect can be enhanced, and interest in the game can be increased.

(26) The fluctuation pattern determination table T11 is a table in which a miss reach fluctuation pattern can be determined, and the fluctuation pattern determination table T14 has a lower determination probability for a miss reach fluctuation pattern to be determined than the fluctuation pattern determination table T11, and is a determination condition in which a miss reach fluctuation pattern is not determined. Therefore, in the high base state, a jackpot based on the pattern Za is obtained, and when the system is controlled to the first high base state and the second high base state after the jackpot game ends, a jackpot based on the pattern ZA is obtained, and a miss reach fluctuation pattern is more difficult to determine than when the system is controlled to the first high base state after the jackpot game ends. Therefore, the special game can be played smoothly, and interest in the game can be increased.

(27) The fluctuation pattern determination tables T11 and T14 have determination conditions with a lower probability of determining a miss reach effect fluctuation pattern than the fluctuation pattern determination table T01. Therefore, when controlled to a high base state, a miss reach fluctuation pattern is more difficult to determine than when controlled to a low base state, allowing the execution of the special game to proceed smoothly and increasing interest in the game.

(28) Presentation mode MD is a presentation mode that is controlled when a jackpot based on pattern Za occurs in the high base state and when the jackpot game is controlled to the first high base state and when the jackpot game is controlled to the second high base state after the jackpot game is completed. Presentation mode MC is a presentation mode that is controlled when a jackpot based on pattern Za occurs in the low base state and when the jackpot game is controlled to the first high base state after the jackpot game is completed. Therefore, it is possible to control to presentation mode MD in the same way when a jackpot based on pattern Za occurs in the high base state and when the jackpot game is controlled to the first high base state and when the jackpot game is controlled to the second high base state after the jackpot game is completed. Therefore, it is possible to standardize the presentation mode, improve the presentation effect, and increase interest in the game.

(29) In addition, when a jackpot based on the pattern Za occurs in the high base state and control is made to the first high base state after the jackpot game ends, it is possible to control to different presentation modes when a jackpot based on the pattern Za occurs in the low base state and control is made to the first high base state after the jackpot game ends. Therefore, it is possible to enhance the presentation effect and increase interest in the game.

(30) Presentation mode MB is a presentation mode that is controlled when a jackpot based on pattern ZA occurs and the system is controlled to the first high base state after the jackpot game ends. Presentation mode MD is a presentation mode that is controlled both when a jackpot based on pattern Za occurs in the high base state and when the system is controlled to the first high base state after the jackpot game ends and when the system is controlled to the second high base state. It is possible to control to different presentation modes when a jackpot based on pattern Za occurs in the high base state and the system is controlled to the first high base state after the jackpot game ends, and when a jackpot based on pattern Za occurs and the system is controlled to the first high base state after the jackpot game ends. Therefore, the presentation effect can be enhanced, and interest in the game can be increased.

(31) Presentation mode MD is a presentation mode that can be controlled continuously for at least multiple consecutive special games among the special games from the start to the end of control to the high base state when a jackpot based on the pattern Za occurs in the high base state, and when the jackpot game is controlled to the first high base state and when the jackpot game is controlled to the second high base state. Therefore, it is possible to control to presentation mode MD in multiple consecutive special games in the same way when a jackpot based on the pattern Za occurs in the high base state, and when the jackpot game is controlled to the first high base state and when the jackpot game is controlled to the second high base state. Therefore, it is possible to standardize the presentation mode, improve the presentation effect, and increase interest in the game.

(32) Presentation mode MA is a presentation mode that is controlled from being controlled to the low base state until being controlled to the second high base state when a jackpot based on pattern Za occurs, and after the jackpot game ends, the game is controlled to the first high base state, then the low base state, and then the game is controlled to the second high base state. For this reason, it is possible to control to presentation mode MA in the low base state in the same way when a jackpot based on pattern Za occurs in the high base state and the game is controlled to the first high base state after the jackpot game ends, and when a jackpot based on pattern Za occurs in the low base state and the game is controlled to the first high base state after the jackpot game ends. Therefore, it is possible to standardize the presentation mode, improve the presentation effect, and increase interest in the game.

(33) The normal variable member 30 has a different opening mode during normal winning play in the first high base state and the second high base state. This allows for diversity in the conditions for control to the high base state and the types of high base states, and also draws attention to the conditions for control to the high base state and the types of high base states. Furthermore, it also draws attention to the opening mode during normal winning play, thereby increasing interest in the game.

(34) The multiple types of opening modes of the normal variable member 30 in the first high base state are different from the single type of opening mode of the normal variable member 30 in the second high base state. Therefore, it is possible to provide diversity to the opening mode of the normal variable member 30 in the first high base state, and by making the opening mode different from that in the second high base state, it is possible to draw attention to whether the normal variable member 30 is being controlled in the first high base state or the second high base state, thereby increasing interest in the game.

(35) The multiple types of opening modes as the opening modes of the normal variable member 30 in the first high base state have the same total upper limit opening time during which the second starting hole 29 can be in the open state in one normal winning game. Therefore, it is possible to provide diversity to the opening modes of the normal variable member 30 in the first high base state, and by setting the same total upper limit opening time for the multiple types of opening modes, it is possible to maintain fairness regarding the entry of game balls into the second starting hole 29, thereby increasing interest in the game.

(36) The normal winning lottery is a lottery that has the same probability of winning in the first high base state and the second high base state, and the fluctuation time of the normal game is the same in the first high base state and the second high base state. Therefore, the probability of winning the normal winning lottery can be made the same in the first high base state and the second high base state, and the fluctuation time of the normal game can be made the same, so that fairness can be maintained in the frequency of the normal winning lottery and the normal game, and interest in the game can be increased.

(37) The opening state of the normal variable member 30 in the first high base state and the opening state of the normal variable member 30 in the second high base state have different total upper limit opening times during which the second starting hole 29 can be in an open state in one normal winning game. This makes it possible to vary the degree of advantage of the opening state of the normal variable member 30, thereby increasing interest in the game.

(38) The normal win game granted in the second high base state has a shorter upper limit control time for the normal win game than the normal win game granted in the first high base state. Therefore, the second high base state can increase the possibility of consuming the normal win game faster than the first high base state, and can draw attention to the type of high base state and the upper limit control time for the normal win game, thereby increasing interest in the game.

(39) The opening state of the normal variable member 30 in the second high base state is longer than the opening state of the normal variable member 30 in the first high base state in terms of the total upper limit opening time during which the second starting hole 29 can be in the open state in one normal winning game. This makes it possible to differentiate the degree of advantage regarding the total upper limit opening time between the first high base state and the second high base state, and to draw attention to the type of high base state and the total upper limit opening time, thereby increasing interest in the game.

(40) The normal winning game granted in the first high base state and the normal winning game granted in the second high base state have different maximum opening times that the normal variable member 30 can be in the open state in one normal winning game, which draws attention to the type of high base state and the maximum opening times, thereby increasing interest in the game.

(41) The multiple types of opening modes as the opening mode of the normal variable member 30 in the first high base state are opening modes in which the normal variable member 30 can be in the open state multiple times in one normal winning game. The multiple types of opening modes have the same maximum opening number of times the normal variable member 30 can be in the open state in one normal winning game and the same closing time in which the normal variable member 30 can be in the closed state in one normal winning game, and the maximum opening time in which the second starting port 29 can be in the open state once is different. For this reason, the multiple types of opening modes for the opening mode of the normal variable member 30 in the first high base state have the same maximum opening number of times and closing time, while the maximum opening time is different, thereby providing diversity to the opening mode of the normal variable member 30 and drawing attention to the maximum opening time, thereby improving interest in the game.

(42) When controlled to the second high base state, after the special game has been played a special number of times, a second entry performance is executed, which can specify that the player will be controlled to the high base state (second high base state). Therefore, by executing the second entry performance when controlled to the second high base state, it becomes possible to specify that the player will be controlled to the high base state, which can heighten expectations for being controlled to the high base state and increase interest in the game.

(43) When the machine is controlled to the first high base state after the end of a jackpot game, a first entry performance is executed, which can specify that the machine will be controlled to the high base state (first high base state) from the timing during the jackpot game. Therefore, even when the machine is controlled to the first high base state after the end of a jackpot game, the first entry performance is executed, which can specify that the machine will be controlled to the high base state (first high base state), thereby heightening the anticipation of being controlled to the high base state (first high base state) and increasing interest in the game.

[Second embodiment]
Next, a second embodiment of the present invention will be described.
In the first embodiment, the jackpot based on the symbol Za is a jackpot of a special game in which the game ball is easy to pass through the special passing area 36, and the first upper limit number of times is different depending on whether the jackpot based on the symbol Za is in a high base state or in a low base state, but this is not limited to this. In the second embodiment, there is a jackpot of a special game in which the game ball is hard to pass through the special passing area 36, and the first upper limit number of times may be different depending on whether the jackpot is in a high base state or in a low base state. In the following description, the same reference numerals are used for configurations and control contents similar to those of the first embodiment already described, and duplicate descriptions are omitted or simplified.

As shown in FIG. 11, in the second embodiment, of the 100 types of jackpot patterns displayed on the second special pattern display section 22b as the game result of the second special game, 25 types of jackpot patterns are classified as Za, 55 types of jackpot patterns are classified as Zb, and 20 types of jackpot patterns are classified as Zc.

As shown in FIG. 12, for each jackpot game, distribution control information is set that indicates the control content of the distribution member 38. The start condition for the long distribution control is that in a jackpot game based on the symbols Za and Zb, the number of game balls detected by the special winning sensor SE3 in an operating round game reaches "2". On the other hand, the start condition for the long distribution control is not that in a jackpot game based on the symbols ZA and Zc, the start condition for the long distribution control is not that in an operating round game.

In addition, in the jackpot game based on the Za and Zb patterns, short distribution control and long distribution control are performed in the first round of play. In the jackpot game based on the ZA and Zc patterns, short distribution control is performed in the first round of play, but long distribution control is not performed. Therefore, in the jackpot game based on the Za and Zb patterns, at least an operating round game that allows the game ball to pass through the special passing area 36 is performed, while in the jackpot game based on the ZA and Zc patterns, an operating round game that allows the game ball to pass through the special passing area 36 is not performed. In other words, it can be said that a jackpot based on ZA and Zc is a jackpot that is less likely to be controlled to a high probability state after the jackpot game ends than a jackpot based on Za and Zb.

As shown in FIG. 11, if the jackpot lottery is won and a jackpot based on pattern Zc is determined, the first upper limit number of times is 100 times both when the machine is controlled to the high probability state and when the machine is controlled to the low probability state after the jackpot play ends. In this way, if the jackpot lottery is won and a jackpot based on pattern Zc is determined, the first upper limit number of times is the same as the specified number of times controlled to the high probability state. Also, if the jackpot lottery is won in a low base state and a jackpot based on pattern Zc is determined, the first upper limit number of times is 100 times when the machine is controlled to the low probability state after the jackpot play ends.

On the other hand, if the jackpot lottery is won in a high base state and a jackpot based on the Zc pattern is determined, when the jackpot game is controlled to a low probability state after the jackpot game ends, the first upper limit number of times will be 597 times, which is greater than 100 times. Also, if the jackpot lottery is won in a high base state and a jackpot based on the Za pattern is determined, when the jackpot game is controlled to a high probability state after the jackpot game ends, the first upper limit number of times will be 697 times, which is greater than 100 times.

In a jackpot game based on the symbols ZA and Zc, since it is difficult for the game ball to pass through the special passing area 36, there is a high possibility that the game will be controlled to a low probability state after the jackpot game ends. On the other hand, in a jackpot game based on the symbols Za and Zb, since it is easy for the game ball to pass through the special passing area 36, there is a high possibility that the game will be controlled to a high probability state after the jackpot game ends. In particular, among the jackpot games based on the symbols Za to Zc, in a jackpot game based on the symbol Zc, the total opening time of the special variable member 32 in one jackpot game is short, and it can be said that it is a jackpot game in which it is difficult for the game ball to pass through the special passing area 36. For this reason, if the jackpot lottery is won in a high base state and a jackpot based on the symbol Zc is determined, the first upper limit number of times is greater than in other cases. For this reason, if a jackpot based on the symbol Zc is determined in a high base state, the first upper limit number of times is greater than in other cases.

In this way, the first high base state is a game state in which the upper limit number of special games that can be controlled after the end of a jackpot game differs between when a jackpot based on pattern Zc occurs in the high base state and when it is not. Also, the first high base state is a game state in which the upper limit number of special games that can be controlled after the end of a jackpot game differs between when a jackpot based on pattern Zc occurs in the high base state and when it is controlled to a low probability state and when it is controlled to a high probability state.

In particular, when a jackpot based on the pattern Zc occurs in the high base state, if the jackpot game is ended and the game is controlled to the high probability state and the first high base state, the 1st to 697th special games are controlled to the first high base state, the 698th special game is controlled to the low base state, and the 699th to 1458th special games are controlled to the second high base state. When a jackpot based on the pattern Zc occurs in the high base state and the game is controlled to the low probability state and the first high base state after the jackpot game is ended, the 1st to 597th special games are controlled to the first high base state, the 598th special game is controlled to the low base state, and the 599th to 1358th special games are controlled to the second high base state. In this way, when a jackpot based on the pattern Zc occurs in the high base state and the game is controlled to the first high base state after the jackpot game is ended, the number of times the special game is executed from the low base state to the second high base state is one. On the other hand, in other cases, it will be 498 or 598 times.

In other words, when the machine is controlled to the first high base state after the end of a jackpot game and then controlled to the low base state, the number of times the special game is executed from being controlled to the low base state until being controlled to the second high base state is smaller when a jackpot based on the pattern Zc occurs in the high base state than otherwise. In particular, when a jackpot based on the pattern Zc occurs in the high base state and the machine is controlled to the first high base state after the end of a jackpot game and then controlled to the low base state, the number of times the special game is executed from being controlled to the low base state until being controlled to the second high base state is smaller than the first upper limit number of times, and in particular smaller than the reserved upper limit number of each special game.

In this embodiment, when comparing the total opening time of the special variable member 32 during one jackpot game, the possibility of being controlled to a high probability state after the jackpot game ends, and the number of times the special game is played that is controlled to a high base state after the jackpot game ends, it can be said that the second special game is a more advantageous special game for the player than the first special game.

In this embodiment, when the second special game is executed in the high base state and a jackpot based on the pattern Zc is won, the jackpot game has a small upper limit on the number of rounds of play, and there is a high possibility that the game will be controlled to a low probability state after the jackpot game ends, in which case the game progresses in a manner that is disadvantageous to the player. On the other hand, after the jackpot game ends, it is possible to control the game to the first high base state and the second high base state, even though it spans one special game, and the degree of advantage for the player can be improved.

In this embodiment, a jackpot based on the Zc symbol corresponds to a specific jackpot and a second jackpot. In this embodiment, when a jackpot based on the Zc symbol occurs in a high base state, the first condition that is established after the jackpot game based on the Zc symbol ends corresponds to the first special condition, and when a jackpot based on the Zc symbol occurs in a low base state, the first condition that is established after the jackpot game based on the Zc symbol ends corresponds to the second special condition. In this embodiment, when a jackpot based on the ZA symbol occurs, the first condition that is established after the jackpot game based on the ZA symbol ends corresponds to the first specific condition, and when a jackpot based on the Zc symbol occurs in a high base state, the first condition that is established after the jackpot game based on the Zc symbol ends corresponds to the second specific condition.

In the jackpot processing, when a jackpot based on the symbols Za and Zb is determined, the condition for starting the long distribution control is met when the number of game balls entering the large prize opening 31 in the first round of play as the second operating round of play reaches "2". Then, the main control CPU 40a operates the distribution member 38 to assume the first distribution state based on the long distribution control. Note that, when a jackpot based on the symbols ZA and Zc is determined, the main control CPU 40a does not perform the long distribution control in the first round of play.

In the game state processing, when the main control CPU 40a determines that the game state when the jackpot lottery is won is a high base state, that the type of jackpot is a jackpot based on the pattern Zc, and that the game ball has passed through the special passing area 36 during the jackpot game, it specifies "697" as the first upper limit number of times. When the main control CPU 40a determines that the game state when the jackpot lottery is won is a high base state, that the type of jackpot is a jackpot based on the pattern Zc, and that the game ball has not passed through the special passing area 36 during the jackpot game, it specifies "597" as the first upper limit number of times. In all other cases, the main control CPU 40a specifies "100" as the first upper limit number of times.

In this way, in this embodiment, the first upper limit number of times is a different number of times when the jackpot lottery is won in a high base state and a jackpot based on pattern Zc is determined as the type of jackpot from other cases. Also, in this embodiment, the first upper limit number of times is a different number of times when the jackpot lottery is won in a high base state and a jackpot based on pattern Zc is determined as the type of jackpot when the jackpot game ends and the game is controlled to a low probability state and a high probability state.

In detail, in this embodiment, if the main control CPU 40a has a jackpot based on the pattern Zc in the high base state and has controlled to the high probability state and the first high base state after the jackpot game ends, the main control CPU 40a controls to the low base state when 697 special games are played without winning the jackpot lottery. If the main control CPU 40a has a jackpot based on the pattern Zc in the high base state and has controlled to the low probability state and the first high base state after the jackpot game ends, the main control CPU 40a controls to the low base state when 597 special games are played without winning the jackpot lottery. On the other hand, if the main control CPU 40a has a jackpot based on the patterns ZA, Za, Zb, or has a jackpot based on the pattern Zc in the low base state and has controlled to the first high base state, the main control CPU 40a controls to the low base state when 100 special games are played without winning the jackpot lottery.

In the game state processing of the sub-control board 41, when the sub-control CPU 41a determines that the game state when the jackpot lottery is won is a high base state, that the type of jackpot is a jackpot based on the pattern Zc, and that the game ball has passed through the special passing area 36 during the jackpot game, it determines "697" as the first upper limit number of times. When the sub-control CPU 41a determines that the game state when the jackpot lottery is won is a high base state, that the type of jackpot is a jackpot based on the pattern Zc, and that the game ball has not passed through the special passing area 36 during the jackpot game, it determines "597" as the first upper limit number of times. In all other cases, the sub-control CPU 41a determines "100" as the first upper limit number of times.

The fluctuation pattern determination table T12 is a table that is referenced when a jackpot based on the patterns Za and Zb occurs, and the current game state is the first high base state after the jackpot game ends, except for the 100th special game.The fluctuation pattern determination table T12 is a table that is referenced when a jackpot based on the pattern Zc occurs in a low base state, and the current game state is the first high base state after the jackpot game ends, except for the 100th special game.

The fluctuation pattern determination table T13 is a table that is referenced when a jackpot based on the symbols Za and Zb occurs, and the current game state is the first high base state in the 100th special game after the jackpot game ends.The fluctuation pattern determination table T13 is a table that is referenced when a jackpot based on the symbol Zc occurs in a low base state, and the current game state is the first high base state in the 100th special game after the jackpot game ends.

The fluctuation pattern determination table T14 is a table that is referenced when a jackpot based on the pattern Zc occurs in a high base state and the current game state is the first high base state after the jackpot game ends.The fluctuation pattern determination table T14 is a table that is referenced when the current game state is the second high base state.

In the second embodiment, when the main control CPU 40a determines that the game state when the jackpot lottery is won is a high base state, the type of jackpot is a jackpot based on the pattern Zc, and the game ball has passed through the special passing area 36 during the jackpot game, it sets the variation count counter to "697" as the first upper limit number. When the main control CPU 40a determines that the game state when the jackpot lottery is won is a high base state, the type of jackpot is a jackpot based on the pattern Zc, and the game ball has not passed through the special passing area 36 during the jackpot game, it sets the variation count counter to "597" as the first upper limit number. In all other cases, the main control CPU 40a sets the variation count counter to "100" as the first upper limit number.

As shown in FIG. 13, when a jackpot based on the symbols Za and Zb is obtained, whether the machine is controlled to a low base state or a high base state, the machine transitions to presentation mode MC after the jackpot game ends. When the machine is controlled to a low base state and a jackpot based on the symbol Zc is obtained, the machine transitions to presentation mode MC after the jackpot game ends. When the machine is controlled to a high base state and a jackpot based on the symbol Zc is obtained, the machine transitions to presentation mode MD after the jackpot game ends. In this way, presentation mode MD can be said to be a presentation mode that is used both when a jackpot based on the symbol Zc is obtained when the machine is controlled to a high base state, and when a special game is played a special number of times after the machine is controlled to a low probability state.

In this embodiment, when the sub-control CPU 41a determines that the jackpot is based on the pattern Zc in a high base state, it sets the presentation mode flag to information indicating the presentation mode MD. When the sub-control CPU 41a determines that the jackpot is based on the patterns Za and Zb, or that the jackpot is based on the pattern Zc in a low base state, it sets the presentation mode flag to information indicating the presentation mode MC.

In this way, presentation mode MC is a presentation mode that occurs when a jackpot based on pattern Zc occurs in the low base state, and is transitioned to (controlled) when control is made to the first high base state after the jackpot game ends. In other words, presentation mode MC is a presentation mode that occurs when a jackpot based on pattern Zc occurs in the low base state, and after control is made to the first high base state after the jackpot game ends, can be continuously controlled in at least multiple consecutive special games among the special games from the start to the end of control to the first high base state.

Presentation mode MD is a presentation mode that is transitioned to (controlled) when a jackpot based on pattern Zc occurs in the high base state and control is exercised to the first high base state after the jackpot play ends, and is a presentation mode that can be continuously controlled thereafter for at least multiple consecutive special games among the special games from the start to the end of control to the first high base state.

As shown in Figures 14(a) and 14(b), in the second embodiment, if a jackpot occurs based on the symbols Za and Zb and the system is controlled to the first high base state after the jackpot game ends, this is the same as in the first embodiment, where a jackpot occurs based on the symbols Zb and Zc and the system is controlled to the first high base state after the jackpot game ends. In the second embodiment, if a jackpot occurs based on the symbol Zc and the system is controlled to the first high base state after the jackpot game ends, this is the same as in the first embodiment, where a jackpot occurs based on the symbol Za and the system is controlled to the first high base state after the jackpot game ends.

[Third embodiment]
Next, a third embodiment of the present invention will be described.
In the first embodiment, the jackpot based on the symbol Za is the jackpot of the second special game, and the first upper limit number of times is different depending on whether the jackpot based on the symbol Za occurs in a high base state or in a low base state, but this is not limited to this. In the third embodiment, the first upper limit number of times may be different depending on whether the jackpot of the first special game occurs in a high base state or in a low base state. In the following description, the same reference numerals are used for configurations and control contents similar to those of the first embodiment already described, and duplicate descriptions are omitted or simplified.

As shown in FIG. 15, in the third embodiment, the first upper limit number of times is 100 times both when the machine is controlled to the high probability state and when the machine is controlled to the low probability state after the end of the jackpot game, except when the machine wins the jackpot lottery and a jackpot based on the ZA pattern is determined. In this way, the first upper limit number of times is the same as the specified number of times controlled to the high probability state, except when the machine wins the jackpot lottery and a jackpot based on the ZA pattern is determined. Also, if the machine wins the jackpot lottery in a low base state and a jackpot based on the ZA pattern is determined, the first upper limit number of times is 100 times when the machine is controlled to the low probability state after the end of the jackpot game.

On the other hand, if the jackpot lottery is won in a high base state and a jackpot based on the ZA pattern is determined, when the jackpot game is controlled to a low probability state after the jackpot game ends, the first upper limit number of times will be 597 times, which is greater than 100 times. Also, if the jackpot lottery is won in a high base state and a jackpot based on the ZA pattern is determined, when the jackpot game is controlled to a high probability state after the jackpot game ends, the first upper limit number of times will be 697 times, which is greater than 100 times.

Furthermore, in a jackpot game based on the ZA pattern, since it is difficult for the game ball to pass through the special passing area 36, there is a high possibility that the game will be controlled to a low probability state after the jackpot game ends. In particular, in a jackpot game based on the ZA pattern, the total opening time of the special variable member 32 in one jackpot game is shorter than in a jackpot game based on the Za or Zb patterns, and it can be said that this is a jackpot game in which it is difficult for the game ball to pass through the special passing area 36. For this reason, if the jackpot lottery is won in a high base state and a jackpot based on the ZA pattern is determined, the first upper limit number of times will be greater than in other cases. For this reason, if a jackpot based on the ZA pattern is determined in a high base state, the first upper limit number of times will be greater than in other cases.

In this way, the first high base state is a game state in which the upper limit number of special games that can be controlled after the end of a jackpot game differs between when a jackpot based on pattern ZA occurs in the high base state and when it is not. Also, the first high base state is a game state in which the upper limit number of special games that can be controlled after the end of a jackpot game differs between when a jackpot based on pattern ZA occurs in the high base state and when it is controlled to a low probability state and when it is controlled to a high probability state.

In particular, when a jackpot based on the ZA symbol is hit in the high base state, if the jackpot game is ended and the game is controlled to the high probability state and the first high base state, the 1st to 697th special games are controlled to the first high base state, the 698th special game is controlled to the low base state, and the 699th to 1458th special games are controlled to the second high base state. When a jackpot based on the ZA symbol is hit in the high base state and the game is controlled to the low probability state and the first high base state after the jackpot game is ended, the 1st to 597th special games are controlled to the first high base state, the 598th special game is controlled to the low base state, and the 599th to 1358th special games are controlled to the second high base state. In this way, when a jackpot based on the ZA symbol is hit in the high base state and the game is controlled to the first high base state after the jackpot game is ended, the number of times the special game is executed from the low base state to the second high base state is one. On the other hand, in other cases, it will be 498 or 598 times.

In other words, when the machine is controlled to the first high base state after the end of a jackpot game and then controlled to the low base state, the number of times the special game is executed from being controlled to the low base state until being controlled to the second high base state is smaller when a jackpot based on the pattern ZA occurs in the high base state than otherwise. In particular, when a jackpot based on the pattern ZA occurs in the high base state and the machine is controlled to the first high base state after the end of a jackpot game and then controlled to the low base state, the number of times the special game is executed from being controlled to the low base state until being controlled to the second high base state is smaller than the first upper limit number of times, and in particular smaller than the upper limit number of reserved special games for each special game.

In this embodiment, when comparing the total opening time of the special variable member 32 during one jackpot game, the possibility of being controlled to a high probability state after the jackpot game ends, and the number of times the special game is played that is controlled to a high base state after the jackpot game ends, it can be said that the second special game is a more advantageous special game for the player than the first special game.

In this embodiment, when the first special game is executed and a jackpot based on the symbol ZA is won, the jackpot game has a smaller upper limit number of rounds than the jackpot based on the symbols Za and Zb, and there is a high possibility that the game will be controlled to a low probability state after the jackpot game ends, in which case the game progresses in a disadvantageous manner for the player. In particular, even if the game is controlled to a high base state, if the execution of the second special game is not suspended and the first special game is executed and a jackpot based on the symbol ZA is won, there is a high possibility that the game will be controlled to a low probability state after the jackpot game ends, in which case the game progresses in a disadvantageous manner for the player. On the other hand, when the first special game is executed in a high base state and a jackpot based on the symbol ZA is won, after the jackpot game ends, it is possible to control to the first high base state and the second high base state, even though it spans one special game, and the degree of advantage for the player can be improved.

In this embodiment, a jackpot based on the ZA symbol corresponds to a specific jackpot and a first jackpot, and a jackpot based on the Za symbol corresponds to a second jackpot. In this embodiment, when a jackpot based on the ZA symbol occurs in a high base state, the first condition that is established after the jackpot game based on the ZA symbol ends corresponds to the first special condition, and when a jackpot based on the ZA symbol occurs in a low base state, the first condition that is established after the jackpot game based on the ZA symbol ends corresponds to the second special condition. In this embodiment, when a jackpot based on the ZA symbol occurs, the first condition that is established after the jackpot game based on the ZA symbol ends corresponds to the first specific condition, and when a jackpot based on the Za symbol occurs in a high base state, the first condition that is established after the jackpot game based on the Za symbol ends corresponds to the second specific condition.

In the game state processing, when the main control CPU 40a determines that the game state when the jackpot lottery is won is a high base state, that the type of jackpot is a jackpot based on the ZA pattern, and that the game ball has passed through the special passing area 36 during the jackpot game, it specifies "697" as the first upper limit number of times. When the main control CPU 40a determines that the game state when the jackpot lottery is won is a high base state, that the type of jackpot is a jackpot based on the ZA pattern, and that the game ball has not passed through the special passing area 36 during the jackpot game, it specifies "597" as the first upper limit number of times. In all other cases, the main control CPU 40a specifies "100" as the first upper limit number of times.

In this way, in this embodiment, the first upper limit number of times is a different number of times when the jackpot lottery is won in a high base state and a jackpot based on the ZA pattern is determined as the type of jackpot from other cases. Also, in this embodiment, the first upper limit number of times is a different number of times when the jackpot lottery is won in a high base state and a jackpot based on the ZA pattern is determined as the type of jackpot when the jackpot game ends and the state is controlled to a low probability state and a high probability state.

In detail, in this embodiment, if the main control CPU 40a has won a jackpot based on the pattern ZA in the high base state and has controlled to the high probability state and the first high base state after the jackpot game ends, the main control CPU 40a controls to the low base state when 697 special games have been played without winning the jackpot lottery. If the main control CPU 40a has won a jackpot based on the pattern ZA in the high base state and has controlled to the low probability state and the first high base state after the jackpot game ends, the main control CPU 40a controls to the low base state when 597 special games have been played without winning the jackpot lottery. On the other hand, if the main control CPU 40a has won a jackpot based on the pattern Za to Zc, or has won a jackpot based on the pattern ZA in the low base state and has controlled to the first high base state, the main control CPU 40a controls to the low base state when 100 special games have been played without winning the jackpot lottery.

In the game state processing of the sub-control board 41, when the sub-control CPU 41a determines that the game state when the jackpot lottery is won is a high base state, that the type of jackpot is a jackpot based on the ZA pattern, and that the game ball has passed through the special passing area 36 during the jackpot game, it determines "697" as the first upper limit number of times. When the sub-control CPU 41a determines that the game state when the jackpot lottery is won is a high base state, that the type of jackpot is a jackpot based on the ZA pattern, and that the game ball has not passed through the special passing area 36 during the jackpot game, it determines "597" as the first upper limit number of times. In all other cases, the sub-control CPU 41a determines "100" as the first upper limit number of times.

The fluctuation pattern determination table T11 is a table that is referenced when a jackpot based on the ZA pattern occurs in a low base state, and after the jackpot play ends, the current game state is the first high base state, except for the 100th special game.

The variation pattern determination table T12 is a table that is referenced when a jackpot is reached based on the symbols Za to Zc, and the current game state is in the first high base state after the jackpot game ends, except for the 100th special game.

The fluctuation pattern determination table T13 is a table that is referenced when a jackpot based on the symbols Za to Zc occurs, and the current game state is the first high base state in the 100th special game after the jackpot game ends.The fluctuation pattern determination table T13 is a table that is referenced when a jackpot based on the symbols ZA occurs in a low base state, and the current game state is the first high base state in the 100th special game after the jackpot game ends.

The fluctuation pattern determination table T14 is a table that is referenced when a jackpot based on the ZA pattern occurs in a high base state and the current game state is the first high base state after the jackpot game ends.The fluctuation pattern determination table T14 is a table that is referenced when the current game state is the second high base state.

In this embodiment, the fluctuation pattern determination condition that references the fluctuation pattern determination table T12 corresponds to the second specific determination condition. In this embodiment, the fluctuation pattern determination condition that references the fluctuation pattern determination table T11 corresponds to the second special determination condition. In this embodiment, the fluctuation pattern determination condition that references the fluctuation pattern determination table T14 corresponds to the first special determination condition and the first specific determination condition.

When the main control CPU 40a determines that the game state when the jackpot lottery is won is a high base state, that the type of jackpot is a jackpot based on the ZA pattern, and that the game ball has passed through the special passing area 36 during the jackpot game, it sets the variation count counter to "697" as the first upper limit number. When the main control CPU 40a determines that the game state when the jackpot lottery is won is a high base state, that the type of jackpot is a jackpot based on the ZA pattern, and that the game ball has not passed through the special passing area 36 during the jackpot game, it sets the variation count counter to "597" as the first upper limit number. In all other cases, the main control CPU 40a sets the variation count counter to "100" as the first upper limit number.

As shown in FIG. 16, when a jackpot based on the symbols Za to Zc is obtained, whether the machine is controlled to a low base state or a high base state, the machine transitions to presentation mode MC after the jackpot game ends. When the machine is controlled to a low base state and a jackpot based on the symbol ZA is obtained, the machine transitions to presentation mode MB after the jackpot game ends. When the machine is controlled to a high base state and a jackpot based on the symbol ZA is obtained, the machine transitions to presentation mode MD after the jackpot game ends. In this way, presentation mode MD can be said to be a presentation mode that is used both when a jackpot based on the symbol ZA is obtained when the machine is controlled to a high base state, and when a special game is played a special number of times after the machine is controlled to a low probability state.

In this embodiment, when the sub-control CPU 41a determines that the jackpot is based on the pattern ZA in a high base state, it sets the presentation mode flag to information indicating presentation mode MD. When the sub-control CPU 41a determines that the jackpot is based on the pattern ZA in a low base state, it sets the presentation mode flag to information indicating presentation mode MB. When the sub-control CPU 41a determines that the jackpot is based on the patterns Za to Zc, it sets the presentation mode flag to information indicating presentation mode MC.

In this way, presentation mode MB is a presentation mode that occurs when a jackpot based on the ZA pattern occurs in the low base state, and is transitioned to (controlled) when control is made to the first high base state after the jackpot game ends. In other words, presentation mode MB is a presentation mode that occurs when a jackpot based on the ZA pattern occurs in the low base state, and after control is made to the first high base state after the jackpot game ends, can be continuously controlled in at least multiple consecutive special games among the special games from the start to the end of control to the first high base state.

The presentation mode MC is a presentation mode that is entered (controlled) when a jackpot based on the symbols Za to Zc occurs and control is exercised to the first high base state after the jackpot play ends, and can then be continuously controlled in at least multiple consecutive special games among the special games from the start to the end of control to the first high base state.

The presentation mode MD is a presentation mode that is transitioned to (controlled) when a jackpot based on the pattern ZA occurs in the high base state and control is exercised to the first high base state after the jackpot play ends, and is then a presentation mode that can be continuously controlled in at least multiple consecutive special games among the special games from the start to the end of control to the first high base state.

In this embodiment, presentation mode MA corresponds to the normal presentation mode, presentation mode MB corresponds to the second special presentation mode, presentation mode MC corresponds to the second specific presentation mode, and presentation mode MD corresponds to the first special presentation mode and the first specific presentation mode.

Here, the game state, the conditions for determining the variation pattern, and the presentation mode will be described in detail with reference to FIG.
As shown in Figures 17(a) and 17(b), in the third embodiment, if the jackpot is based on the symbols Za to Zc and the state is controlled to the first high base state after the jackpot game ends, it is the same as the first embodiment, in which the jackpot is based on the symbols Zb and Zc and the state is controlled to the first high base state after the jackpot game ends. In the third embodiment, if the jackpot is based on the symbol ZA in the low base state and the state is controlled to the first high base state after the jackpot game ends, it is the same as the first embodiment, in which the jackpot is based on the symbol ZA and the state is controlled to the first high base state after the jackpot game ends. In the third embodiment, if the jackpot is based on the symbol ZA in the high base state and the state is controlled to the first high base state after the jackpot game ends, it is the same as the first embodiment, in which the jackpot is based on the symbol Za in the high base state and the state is controlled to the first high base state after the jackpot game ends.

As described above in detail, the third embodiment has the following advantages.
(42) The second special game is a special game that is more advantageous to the player than the first special game. When a jackpot based on the symbol ZA is won in the high base state and the system is controlled to the first high base state after the jackpot game ends, the number of times the special game is executed between being controlled to the low base state and being controlled to the second high base state is smaller than when a jackpot based on the symbol Za is won in the high base state and the system is controlled to the first high base state after the jackpot game ends. Therefore, a special benefit can be given to the player for winning the jackpot lottery in the first special game, which is less advantageous to the player than the second special game, and the player's interest in the game can be increased.

(43) In the high base state, a jackpot based on the ZA pattern is generated, and the system is controlled to the first high base state after the jackpot game is completed, and then controlled to the low base state when 579 or 679 special games are played. On the other hand, when a jackpot based on the Za pattern is generated, the system is controlled to the first high base state after the jackpot game is completed, and then controlled to the low base state when 100 special games are played. Therefore, when a jackpot based on the ZA pattern is generated in the high base state and the system is controlled to the first high base state after the jackpot game is completed, a jackpot based on the Za pattern is generated, and the system is controllable to the first high base state with a larger number of special games than when the system is controlled to the first high base state after the jackpot game is completed. Therefore, in order to specify the number of special games controlled to the first high base state, attention can be drawn to whether the type of jackpot is a jackpot based on the ZA pattern or a jackpot based on the Za pattern, and interest in the game can be increased.

[Fourth embodiment]
Next, a fourth embodiment of the present invention will be described.
In the first to third embodiments, when the first high base state is controlled with 597 times or 697 times as the first upper limit number of times and then the low base state is controlled, the fluctuation pattern determination table T01 is referred to and the performance mode MA is controlled, but this is not limited to this. In the fourth embodiment, when the first high base state is controlled with 597 times or 697 times as the first upper limit number of times and then the low base state is controlled, the fluctuation pattern determination table T14 may be referred to. Also, in the fourth embodiment, when the first high base state is controlled with 597 times or 697 times as the first upper limit number of times and then the low base state is controlled, the performance mode MD may be controlled. In the fourth embodiment, the first embodiment is adopted as a premise configuration, but for example, the second embodiment may be adopted, or the third embodiment may be adopted, and the same effect is obtained.

In the fourth embodiment, a jackpot based on the symbol Za occurs in the high base state, and after the jackpot game ends, the system is controlled to the high probability state and the first high base state, and when the 100th special game ends without winning the jackpot lottery, the system is controlled to the low probability state and the first high base state. Also, after the jackpot game ends, when the 597th special game ends without winning the jackpot lottery, the system is controlled to the low probability state and the low base state, and after the jackpot game ends, when the 598th special game ends without winning the jackpot lottery, the system is controlled to the low probability state and the second high base state.

In this case, after the end of the jackpot game, in the 598th special game without winning the jackpot lottery, the main control CPU 40a refers to the variation pattern determination table T14 to determine the variation pattern. Also, after the end of the jackpot game, in the 598th special game without winning the jackpot lottery, the sub-control CPU 41a controls to the presentation mode MD.

As described above in detail, the fourth embodiment has the following advantages.
(44) The fluctuation pattern determination table T14 is a table from when a jackpot based on the pattern Za occurs in the high base state, and when the jackpot game is ended and the game is controlled to the first high base state and then controlled to the low base state, until the game is controlled to the second high base state. Therefore, the fluctuation pattern determination table T14 is a table when a jackpot based on the pattern Za occurs in the high base state, and when the jackpot game is ended and the game is controlled to the first high base state, when the game is then controlled to the low base state, and when the game is then controlled to the second high base state. When a jackpot based on the pattern Za occurs in the high base state, when the jackpot game is ended and the game is ended and the game is ended, the fluctuation pattern can be determined in the same way based on the fluctuation pattern determination table T14 when the game is ended and the game is ended and the game is ended and the game is ended. Therefore, the presentation effect can be enhanced, and the interest in the game can be improved.

(45) The presentation mode MD is a presentation mode from when a jackpot based on the pattern Za occurs in the high base state, and when the jackpot game is ended and the game is controlled to the first high base state and then controlled to the low base state, until the game is controlled to the second high base state. Therefore, the presentation mode MD is a presentation mode when a jackpot based on the pattern Za occurs in the high base state, and when the jackpot game is ended and the game is controlled to the first high base state, when the game is then controlled to the low base state, and when the game is then controlled to the second high base state. When a jackpot based on the pattern Za occurs in the high base state, the game can be controlled to the presentation mode MD in the same way when the jackpot game is ended and the game is ended and the game is ended and the game is ended and the game is ended. Therefore, the presentation effect can be enhanced, and the interest in the game can be improved.

The above embodiment can be embodied in the following other embodiments (alternative examples).
In the above embodiment, for example, when a specific jackpot occurs in the high base state, the second entry performance may not be executed when the jackpot game ends and the game is controlled from the low base state to the second high base state. The specific jackpot here corresponds to a jackpot based on the Za symbol in the first embodiment, a jackpot based on the Zc symbol in the second embodiment, and a jackpot based on the ZA symbol in the third embodiment. Also, for example, there may be cases where the first entry performance is not executed.

- In the above embodiment, for example, when a specific jackpot occurs in a high base state, after the jackpot play ends, in the 597th or 697th special game, a fluctuation pattern may be determined based on the fluctuation pattern determination table T13, and a final performance may be executed.

- In the above embodiment, for example, when the first high base state is controlled to the low base state after the end of a jackpot game, in the low base state, a notification effect (so-called "countdown effect", "premonition effect") regarding the number of times a special game will be played until the state is controlled to the second high base state may be executed. In particular, for example, when a specific jackpot occurs in the high base state, a notification effect is not executed in the low base state after the end of the jackpot game, but otherwise, a notification effect may be executed in the low base state after the end of the jackpot game.

- In the above embodiment, for example, after the end of a jackpot game, in a high base state (first high base state and second high base state), a notification effect (so-called "right hit notification effect") that can identify that the game ball will flow down to the right side of the game area 21 may be executed. Also, for example, if a specific jackpot occurs in the high base state, and after the end of the jackpot game, the game is controlled to the first high base state, and then controlled to the low base state, in the low base state, a notification effect that can identify that the game ball will flow down to the right side of the game area 21 may be executed, and it is preferable that the notification mode is different.

- In the above embodiment, for example, some or all of the presentation content (presentation style) of the right-hit notification presentation executed in the first high base state and the second high base state may be different.
In the above embodiment, for example, any one of the following may be executed: a notification display capable of specifying that the game ball will not flow down to the left side of the game area 21, a notification display capable of specifying that the game ball will flow down to the left side of the game area 21, and a notification display capable of specifying that the game ball will not flow down to the right side of the game area 21.

- In the above embodiment, the fluctuation pattern determination table T14 is a table in which a miss-reach fluctuation pattern is not determined, but this is not limited thereto, and for example, the fluctuation pattern determination table T14 may be a table in which a miss-reach fluctuation pattern is determined. In this case, for example, the fluctuation pattern determination table T14 is preferably a table in which a miss-reach fluctuation pattern is determined with a determination probability different from that of the fluctuation pattern determination tables T01, T11, and T12, and may be a table in which a miss-reach fluctuation pattern is determined with a determination probability lower than that of the fluctuation pattern determination tables T01, T11, and T12.

- In the above embodiment, for example, a lottery to determine a miss reach fluctuation pattern and a lottery to determine the fluctuation pattern itself may be executed separately. Also, for example, a first lottery to determine the classification of the fluctuation pattern and a second lottery to determine which fluctuation pattern is selected from the classification of the fluctuation pattern determined by the first lottery may be executed separately.

- In the above embodiment, the fluctuation pattern HP35 is determined in the fluctuation pattern determination table T14 and is also determined as the fluctuation pattern of the first special game in the fluctuation pattern determination table T11, but this is not limited to the above. For example, the fluctuation pattern HP35 may be determined as the fluctuation pattern of the second special game in the fluctuation pattern determination table T11. For example, the fluctuation pattern HP35 may be determined as the fluctuation pattern of each special game in the fluctuation pattern determination table T12. For example, the fluctuation pattern HP35 may be determined in another fluctuation pattern determination table, and may not be determined in any table other than the fluctuation pattern determination table T14.

- In the above embodiment, the fluctuation pattern HP53 is determined as the fluctuation pattern of the first special game in the fluctuation pattern determination table T14, and as the fluctuation pattern of the first special game in the fluctuation pattern determination table T12, but this is not limited to this. For example, the fluctuation pattern HP53 may be determined as the fluctuation pattern of the second special game in the fluctuation pattern determination table T12. For example, the fluctuation pattern HP53 may be determined as the fluctuation pattern of each special game in the fluctuation pattern determination table T11. For example, the fluctuation pattern HP53 may be determined in another fluctuation pattern determination table, and may not be determined other than the fluctuation pattern determination table T14. For example, the fluctuation pattern HP53 may be determined as the fluctuation pattern of the second special game in the fluctuation pattern determination table T14, and may be determined as the fluctuation pattern of each special game in the fluctuation pattern determination table T14.

- In the above embodiment, the fluctuation pattern HP54 is determined as the fluctuation pattern of the second special game in the fluctuation pattern determination table T14, and as the fluctuation pattern of the second special game in the fluctuation pattern determination table T12, but this is not limited to this. For example, the fluctuation pattern HP54 may be determined as the fluctuation pattern of the first special game in the fluctuation pattern determination table T12. For example, the fluctuation pattern HP54 may be determined as the fluctuation pattern of each special game in the fluctuation pattern determination table T11. For example, the fluctuation pattern HP54 may be determined in another fluctuation pattern determination table, and may not be determined other than the fluctuation pattern determination table T14. For example, the fluctuation pattern HP54 may be determined as the fluctuation pattern of the first special game in the fluctuation pattern determination table T14, and may be determined as the fluctuation pattern of each special game in the fluctuation pattern determination table T14.

- In the above embodiment, the fluctuation pattern determination tables T11 and T12 were tables in which a miss-reach fluctuation pattern was determined with a higher determination probability than the fluctuation pattern determination table T01, but this is not limited to the above. For example, the fluctuation pattern determination tables T11 and T12 may be tables in which a miss-reach fluctuation pattern was determined with a higher determination probability than the fluctuation pattern determination table T01, or may be tables in which a miss-reach fluctuation pattern was determined with the same determination probability.

- In the above embodiment, for example, in the first high base state, a fluctuation pattern determination table may be referenced to determine the fluctuation pattern in addition to the fluctuation pattern determination tables T11 to T14, and, for example, any of the fluctuation pattern determination tables T11 to T13 may not be present.

- In the above embodiment, for example, in the first special game controlled to the first high base state, a variation pattern determination table that is not referenced in at least any special game other than the first special game in the first high base state may be referenced.

- In the above embodiment, for example, in the second high base state, any one of a plurality of types of fluctuation pattern determination tables may be referenced to determine the fluctuation pattern. In other words, the fluctuation pattern determination table in the second high base state does not include fluctuation pattern determination tables T01, T11, and T12, and it is sufficient to have at least fluctuation pattern determination table T14, and other fluctuation pattern determination tables may also be present.

- In the above embodiment, for example, in the second high base state, one of multiple types of miss fluctuation patterns may be determined, and the determination conditions may differ depending on, for example, the number of special reserved games and the type of special game (first special game or second special game).

- In the above embodiment, for example, in the first special game controlled to the second high base state, the fluctuation pattern may be determined by referring to a fluctuation pattern determination table that is not referenced in at least any special game other than the first special game in the second high base state.

- In the above embodiment, for example, in the last special game controlled to the second high base state, the fluctuation pattern may be determined by referring to a fluctuation pattern determination table that is not referenced in at least any special game other than the last special game in the second high base state.

- In the above embodiment, for example, in the first high base state, the device may be controlled to a presentation mode other than presentation modes MB to MD, and for example, one of presentation modes MB and MC may not be present.

- In the above embodiment, for example, in the first special game controlled to the first high base state, the presentation mode may be controlled to a different presentation mode that is not controlled in at least any special game other than the first special game in the first high base state.

- In the above embodiment, for example, in the second high base state, the display may be controlled to one of a plurality of different presentation modes. In other words, the presentation modes in the second high base state do not include presentation modes MB and MC, and there must be at least presentation mode MD, and other presentation modes may also be included.

- In the above embodiment, for example, in the first special game controlled to the second high base state, the presentation mode may be controlled to a different presentation mode that is not controlled in at least any special game other than the first special game in the second high base state.

- In the above embodiment, for example, in the last special game controlled to the second high base state, the presentation mode may be controlled to a different presentation mode that is not controlled in at least any special game other than the last special game in the second high base state.

- In the above embodiment, after being controlled to one of the presentation modes MB to MD in response to the end of a jackpot game and a change in the game state, the mode is continuously controlled over a number of consecutive special games, but this is not limited to the above. For example, after being controlled to one of the presentation modes MB to MD in response to the end of a jackpot game and a change in the game state, the mode may not be continuously controlled over a number of consecutive special games, but may be controlled for one special game and then controlled to a different presentation mode. In particular, after being controlled to one of the presentation modes MB to MD in response to the end of a jackpot game and a change in the game state, the mode may be controlled to a different presentation mode even if there is no change in the game state.

- In the above embodiment, the same time is determined as the fluctuation time of the normal game in the first high base state and the second high base state, but this is not limited to this. For example, one of multiple times may be determined with the same probability in the first high base state and the second high base state. In other words, the fluctuation time of the normal game may be determined in the same manner in the first high base state and the second high base state. Also, for example, different times may be determined in the first high base state and the second high base state. Also, for example, a shorter time may be more easily determined in the second high base state than in the first high base state, or a shorter time may be more easily determined in the first high base state than in the second high base state.

- In the above embodiment, for example, with regard to the probability of winning the normal winning lottery, in the first high base state, the probability of winning the normal winning lottery may be higher than in the low base state. Also, for example, in the second high base state, the probability of winning the normal winning lottery may be higher than in the low base state. Also, for example, in the first high base state, the probability of winning the normal winning lottery may be higher than in the second high base state, and in the second high base state, the probability of winning the normal winning lottery may be higher than in the first high base state.

- In the above embodiment, the same control may be performed for the normal game and the normal win game, for example, the fluctuation time of the normal game, the probability of determining the fluctuation time of the normal game, the opening mode in the normal win game (upper limit opening time per time, closing time per time, total upper limit opening time, upper limit number of times per time opening, upper limit control time for one normal win game). In this case, the trigger for control will differ between the first high base state and the second high base state, whether it is the first condition or the second condition.

In the above embodiment, for example, the opening manner of the normal variable member 30 in the first high base state may be any one of two types or four or more types, or may be one type.
In the above embodiment, for example, the opening manner of the normal variable member 30 in the second high base state may be any one of two or more types.

In the above embodiment, for example, the opening manner of the normal variable member 30 in the low base state may be any one of two or more types.
In the above embodiment, for example, a high base transition lottery may be performed when a special game is executed. This high base transition lottery may be performed when the execution of the special game starts or when the execution of the special game ends. When the main control CPU 40a wins the high base transition lottery, it controls to the high base state. Such a high base state may be the third high base state. In other words, the high base state may include a third high base state that is controlled when a condition is met when a predetermined lottery is won, and the third high base state may be present separately from the second high base state, or the third high base state may be present instead of the second high base state.

- In the above embodiment, for example, the first upper limit number of times does not have to vary depending on at least one of the type of jackpot, the game state when the jackpot lottery is won, and whether the game is controlled to a high probability state after the jackpot game ends.

- In the above embodiment, the first upper limit number was the same number (100 times) as the specified number of times controlled to continue in the high probability state, but this is not limited thereto, and for example, it may be a number larger than the specified number (e.g., 120 times) or a number smaller than the specified number (e.g., 80 times). In this way, a part or all of the first upper limit number determined as 100 times may be changed to at least one of a number larger than the specified number and a number smaller than the specified number. As a specific example, the first upper limit number may be 120 times when a jackpot based on the pattern Zb occurs.

- In the above embodiment, the second upper limit number may be a number greater than, less than, or the same as the specified number of times that is continuously controlled to be in the high probability state. Also, for example, the second upper limit number may be a number greater than, less than, or the same as the reciprocal of the probability of winning the jackpot lottery in the low probability state.

- In the above embodiment, the special number of times may be greater than, less than, or the same as the specified number of times that is continuously controlled in the high probability state. Also, for example, the special number of times may be greater than, less than, or the same as the reciprocal of the probability of winning the jackpot lottery in the low probability state.

・In the above embodiment, when a specific jackpot is hit in a high base state, the first upper limit number of times is different depending on whether the state is controlled to a high probability state or a low probability state after the end of the jackpot game. However, this is not limited to this, and for example, the first upper limit number of times may be the same. As a specific example, in the first embodiment, when a jackpot based on the pattern Za is hit in a high base state, the first upper limit number of times may be 697 times or the first upper limit number of times may be 597 times both when the state is controlled to a high probability state and when the state is controlled to a low probability state after the end of the jackpot game. In the second embodiment, when a jackpot is hit based on the pattern Zc in a high base state, the first upper limit number of times may be 697 times or the first upper limit number of times may be 597 times both when the state is controlled to a high probability state and when the state is controlled to a low probability state after the end of the jackpot game. In the third embodiment, when a jackpot based on the symbol ZA occurs in the high base state, the first upper limit number of times may be 597 times or 697 times both when the state is controlled to the high probability state and when the state is controlled to the low probability state after the jackpot game ends. In such cases, the variation pattern determination table T14 may be referenced after the jackpot game ends, and the presentation mode MD may be controlled until the special game of the first upper limit number of times is executed.

- In the above embodiment, when a specific jackpot occurs in the high base state, the number of times the special game is executed after the jackpot game ends, from when the game is controlled to the low base state until the game is controlled to the second high base state, is smaller than the first reserved upper limit number, the second reserved upper limit number, and the total reserved upper limit number, and is smaller than 100 times, but is not limited to this. For example, the number of times such a special game is executed may be larger than or the same as the first reserved upper limit number and the second reserved upper limit number, may be larger than or the same as the total reserved upper limit number, or may be larger than or the same as 100 times.

- In the above embodiment, for example, the number of times a special game is executed after the end of a jackpot game from when it is controlled to the low base state until it is controlled to the second high base state may be smaller when a specific jackpot occurs in the low base state than when a specific jackpot occurs in the high base state. For example, the number of times a special game is executed after the end of a jackpot game from when it is controlled to the low base state until it is controlled to the second high base state may be smaller when a first specific jackpot occurs in the high base state than when a second specific jackpot different from the first specific jackpot occurs in the low base state. For example, the number of times a special game is executed after the end of a jackpot game from when it is controlled to the low base state until it is controlled to the second high base state may be smaller when a second specific jackpot occurs in the low base state than when a first specific jackpot occurs in the high base state.

- In the above embodiment, for example, the high probability state may be awarded until the next jackpot game is awarded. Also, for example, a drop lottery may be held, and when the main control CPU 40a has controlled to the high probability state after the end of the jackpot game, it may control to the low probability state when a predetermined control condition is met triggered by winning the drop lottery. In this case, it is impossible to specify whether the state has been controlled from the high probability state to the low probability state before a predetermined number of special games have been played, and the state may be controlled to the high probability state even after a predetermined number of special games have been played.

- In the above embodiment, for example, when the number of game balls entering the big prize opening 31 varies depending on the type of jackpot, the distribution member 38 may be operated to assume the first distribution state based on the long distribution control.

- In the above embodiment, for example, at least one of the short distribution control and the long distribution control may be triggered by the arrival of a predetermined time, rather than the number of game balls that have entered the large prize opening 31 reaching a specified number.

- In the above embodiment, for example, it may be any of the second or subsequent rounds of play, it may be one round of play or multiple rounds of play, it may be consecutive rounds of play or discontinuous rounds of play.

- In the above embodiment, for example, the jackpot in the first special game may be a jackpot through which the game ball is likely to pass through the special passing area 36, and such a jackpot may correspond to a specific jackpot. Also, for example, as in the first and third embodiments, the jackpot in the second special game may not be a jackpot through which the game ball is unlikely to pass through the special passing area 36, and as in the second embodiment, the jackpot in the second special game may be a jackpot through which the game ball is likely to pass through the special passing area 36.

・In the above embodiment, when the game ball passes through the special passing area 36 during a jackpot game, the state is controlled to a high probability state after the jackpot game ends. However, this is not limited to the above, and for example, the state may be controlled to a high probability state after the jackpot game ends based on the type of jackpot. In this case, the special passing area 36 and the distribution member 38 may not be provided. Also, in the above embodiment, a jackpot in which the game ball is likely to pass through the special passing area 36 can be replaced with a jackpot that is controlled to a high probability state after the jackpot game ends (so-called "variable jackpot"), and a jackpot in which the game ball is unlikely to pass through the special passing area 36 can be replaced with a jackpot that is controlled to a low probability state after the jackpot game ends (so-called "non-variable jackpot"). In other words, there may be a jackpot that is controlled to a high probability state after the jackpot game ends and a jackpot that is controlled to a low probability state (not controlled to a high probability state) after the jackpot game ends.

In the above embodiment, for example, a small win lottery may be held separately from a big win lottery.
In the above embodiment, for example, there may be a type of jackpot that results in a low base state after the jackpot game ends.

- In the above embodiment, the second special game is executed with priority over the first special game, but this is not limited thereto. For example, the special games may be executed in the order in which the game balls enter the first starting hole 28 and the second starting hole 29, and for example, the first special game and the second special game may be executed simultaneously.

- In the above embodiment, the main control board 40 and the sub-control board 41 are provided and various functions are mounted, but this is not limited thereto, and for example, the functions of one board may be mounted as functions of the other board. Also, a means for controlling the performance display device 27 may be provided separately. Also, this is not limited to two types of boards, and for example, they may be configured as an integrated board, or three or more types of boards. As a specific example, the functions of the sub-control board 41 may be divided into an overall control board that performs overall control related to the performance, and a display control board that performs control related to the display of images.

- In the above embodiment, the type of jackpot (jackpot game) was specified by the pattern command, but the type of jackpot may also be specified by the game start command or other dedicated control command.

- In the above embodiment, various random number information related to the special game may be stored in a memory area provided according to the special reserved number. In this case, each time a special game is executed, the random number information may be shifted and stored in a memory area from which the special reserved number has been subtracted by "1."

- In the above embodiment, for example, the machine may be a gaming machine in which the special variable member 32 operates to the open state by a predetermined lottery, and a jackpot game is awarded when a gaming ball that enters the large prize entrance 31 passes through a specific passing area (a so-called "two-type gaming machine"). Also, for example, the machine may be a gaming machine in which the special variable member 32 operates to the open state by winning a jackpot lottery in a special game (a so-called "one-type two-type mixed gaming machine"). Also, the machine may be a gaming machine in which a jackpot game starts when a gaming ball enters a predetermined ball entrance (a so-called three-type gaming machine). Also, for example, a high probability state does not have to be awarded.

Next, the technical ideas that can be understood from the above embodiment and other examples will be described below.
(1) A jackpot type determination means is provided for determining the type of jackpot, and the type of jackpot includes a specific jackpot, and the first special condition is a condition that is established after the end of the jackpot game when the jackpot lottery is won in the ball entry rate improvement state and the specific jackpot is determined by the jackpot type determination means, and the second special condition is a condition that is established after the end of the jackpot game when the jackpot lottery is won in the non-ball entry rate improvement state and the specific jackpot is determined by the jackpot type determination means.

(2) The first jackpot is characterized in that it is a jackpot that is less likely to be controlled to the high probability state after the jackpot game ends than the second jackpot, or a jackpot that is not controlled to the high probability state after the jackpot game ends.

(3) When the game state control means controls the game state to the ball winning rate improvement state based on the establishment of the third special condition, the game state control means controls the game state to the ball winning rate improvement state until a predetermined number of pattern change games are executed without winning the jackpot lottery, regardless of the first number of times and the second number of times.

(4) When the game state control means controls the game state to the ball winning rate improvement state based on the establishment of the third specific condition, the game state control means controls the game state to the ball winning rate improvement state until a predetermined number of pattern change games are executed without winning the jackpot lottery, regardless of the first number of times and the second number of times.
