Description

  The present invention relates to a gaming machine such as a pachinko gaming machine, a combination gaming machine (arranged ball gaming machine), a slot machine or the like.

  In gaming machines, a start winning device, a variable display device, and a big winning device are generally arranged in a game area of a game board. In such a gaming machine, “random number value for jackpot lottery (for determining whether or not to win)” is acquired at the timing when the game ball wins the start winning device, and the acquired random number value and a predetermined value (jackpot value) Are matched, and if they match, it is determined to be “big hit”, and if they do not match, it is determined to be “off”. The result of the big hit lottery is shown using a special symbol stop display on the variable display device. In other words, when the lottery result is “big hit”, the special symbol displayed on the variable display device is a big hit symbol (for example, “7,7,7”, “6,6,6”, etc.). In combination, the game is stopped and displayed, and a big hit game (special game) for opening the big prize device is started. If the lottery result is “out”, the special symbol displayed on the variable display device will be out and the three-digit symbols such as “7, 7, 6”, “8, 4, 6” will match. Stop combination). Also, if the special symbol is stopped and displayed on a specific symbol (e.g., a combination of odd symbols with the same three digits) among the jackpot symbols, the jackpot will be displayed for the period from when the jackpot game ends until the next jackpot game is generated. Many of them have a probability variation function that improves the probability of determining a big hit in a lottery.

  In addition, reach variation display may be executed in the variable display at the stage before the big hit symbol or off symbol is stopped on the variable display device, especially when the big hit symbol is stopped and displayed, usually after the change starts. After reaching the reach variation display, it will be stopped and displayed with a jackpot symbol ("Reach", for example, two symbols of the three-digit symbol are the same, and one symbol is different (moving) State). This reach fluctuation display has a long fluctuation display time compared to the normal fluctuation display that does not become reach fluctuation display (for example, the normal fluctuation display is 5 seconds, the reach fluctuation display is 30 to 120 It is possible to enhance the player's taste by setting various display effects. However, the player may need to check the reach fluctuation display carefully, or to prevent the launch of a useless ball in a situation where the hold is full during the long reach change display. May stop firing.

  In addition, after the reach change display and after the stop display with the big hit symbol, the player can prevent the useless ball from being fired even during the period before the big winning device is released, the so-called big hit fanfare period. The game ball may stop firing. In addition, a plurality of opening patterns of the big winning device are set, and when the opening time is selected shorter than the other big hits, it is possible to win even if a game ball is fired. If it is determined that it is difficult, the game ball may be stopped. In this way, when the player stops the launch of the game ball, that is, a so-called stop-off, the operating rate of the gaming machine is lowered, which causes a decrease in sales at the gaming store.

  On the other hand, if the game ball is started and won during the reach fluctuation display for the purpose of suppressing the stoppage of the player during the reach fluctuation display, the lottery result related to the fluctuation display or the lottery held A gaming machine is disclosed that notifies whether the result is a win or a miss before the symbol stops and displays (Patent Documents 1 and 2).

  However, for information on whether the lottery results related to the current fluctuation display are winning or losing, or whether the lottery results related to holding are winning or losing, information on whether the reach fluctuation is being displayed or the holding is full, etc. Even if it is not notified in advance until a useless ball is generated, it is information that is surely notified after that, so that the effectiveness of preventing the player from stopping is poor. Also, even if a game ball is fired while the reach change is being displayed or when the reserve is full, depending on the skill of the player and the adjustment of the nail, it will not be possible to start a prize within a predetermined time and receive a prior notification. In some cases. Thus, there is a problem that the return for the risk of generating a waste ball is low, and the conventional method is poor in effectiveness for preventing the player from stopping.

  The present invention has been made to solve such a problem, and its purpose is to improve the operating rate of the gaming machine by effectively preventing the player from stopping. is there.

In order to achieve the above object, a gaming machine according to the first aspect of the present invention includes a gaming board in which a gaming area is formed, a start winning device provided in the gaming area, a variable winning device provided in the gaming area, A player for launching a game ball in a game area, a launch detector for detecting the launch of a game ball, a launch signal recognizing unit for recognizing input of a signal from the launch detector, and an operation of the launcher A launch instruction means for instructing, a lottery means for lottery winning according to a predetermined lottery probability due to a game ball entering the start winning device, and the lottery means A special game executing means for executing a special game for opening and closing the variable winning device, a probability changing lottery means for executing a probability changing lottery for setting a lottery probability of the lottery means to be a high probability or a low probability, and the probability Floating lottery player When the special game is determined to be successful, after the special game is over, the lottery probability of the lottery means is changed from a low probability to a high probability. In the case where the identification symbol is displayed, the identification symbol is stopped and displayed as a winning symbol.
In both cases where the probability variation lottery unit is determined to be winning and the probability variation lottery unit is not determined to be winning, the identification display of the same type is stopped and displayed on the symbol display unit. A gaming machine in which it is difficult to recognize whether the lottery probability after the end of the special game is a high probability or a low probability depending on the identification symbol that is stopped and displayed,
After the firing instructing unit instructs the player to launch a game ball at a predetermined timing, the firing signal recognizing unit recognizes the input of the signal from the firing detecting unit within a time limit for a predetermined time or more. Informing means for informing at a predetermined reliability whether or not the lottery probability after the end of the special game is a high probability,
When the lottery means determines that the winning is, the time limit is set across the execution time of the variable display of the identification symbol and the opening / closing process execution time for executing the opening / closing process of the variable winning device, The predetermined time is set to be longer than the time from when the firing instruction is given until the variation display of the identification symbol is finished , and longer than the opening / closing process execution time.

According to the gaming machine of the present invention 1, a special game is displayed by stopping and displaying the same type of identification symbols when the probability variation lottery means is determined to be a win (winning the probability variation lottery) and when it is not determined to be a win. When it is difficult to recognize whether the game state after the end (lottery probability) is a high probability state or a low probability state, and when the player performs a launch operation in accordance with the instruction at the timing when the game ball is instructed to launch The gaming state (high probability state or low probability state) that is difficult to recognize is notified. In other words, an operation that can be easily achieved by the player's intention regardless of the skill of “performing the firing operation” is the target of the instruction, and information obtained by following the instruction is continued for the subsequent game. By using the information about the gaming state as an index as to whether or not it is possible to effectively stop the player from stopping.
In addition, if it is recognized that the launch operation has been performed for a predetermined time or more at the time when the limit is set, the game state is notified. I can't.
In addition, in order to achieve input for a predetermined time or more and receive notification, the signal input must be recognized from the stage where the identification symbol, which is the previous stage of the special game, is variably displayed, that is, there is a firing instruction. In such a case, a signal must be input before recognizing whether the lottery result is a hit or miss. Therefore, in the case of winning, an input for a predetermined time or more can be achieved and a notification can be obtained, while in the case of losing, since the lottery result is out, the input for a predetermined time or more without shifting to a special game. Cannot be achieved.
As a result, input (launching of the game ball) will be wasted in the case of detachment, but since the operation of the gaming machine can be ensured during the display of the change of the identification symbol (especially the reach change display), the game is further increased. It is possible to suppress the person's stopping and improve the operating rate of the gaming machine.

Here, “detecting the launch of the game ball” performed by the launch detection means means detecting the launch operation of the player. For example, it may be set as “detection of the launch of a game ball” by detecting that the player is in contact with a touch sensor described later, or it is in contact with the touch sensor and the launch stop switch is turned on. It is good also as "detecting the launch of a game ball" by detecting that there is no, and combining with these or alone, it detects "the game ball by detecting whether the operation amount (rotation amount) of the launch handle is more than a predetermined amount". May be set as “detection of launch of game ball” or may be set as “detection of launch of game ball” by detecting a game ball that has actually been launched. Both are included in the “detection of game ball launch” according to the present invention.
In addition, “stop display of the same type of identification symbol” means that when the probability variation lottery is won and when it is not won, both are displayed with the same symbol (“1, 3, 5”). (1 · 3 · 5 ”,“ 4 · 4 · 4 ”and“ 4 · 4 · 4 ”, etc.), as well as indicating that the two are stopped and displayed in a manner having a relevance to such an extent that they are difficult to distinguish. For example, when both are out-of-reach symbols (“5 ・ 6 ・ 5” and “4 ・ 5 ・ 4”, etc.) and when both are stopped and displayed in the same color (“Blue 2, Blue 4, Blue 6”, etc.) For example, “blue 8 / blue 2 / blue 4”) and the case where both are stopped and displayed with a broken pattern (“126” and “374”).
In addition, the “predetermined timing” is effective in setting a timing at which the player is highly likely to stop the launch of the game ball in order to prevent a decrease in the operating rate of the gaming machine. Specifically, when the hold is full (there may be a case where the hold is not more than a predetermined number even if it is not full), when the reach fluctuation display is performed (in particular, the fluctuation display time is set longer than the normal reach state). (It may be in the long reach state), or in a game state in which the big winning device is released in an open pattern (pattern with a short opening time) that makes it difficult to win a game ball, the winning device will be displayed after the winning symbol is stopped and displayed The so-called jackpot fanfare until the door is opened is exemplified.
Further, “notifying with a predetermined reliability” means that the probability of whether or not the lottery probability is high depends on the notification mode.
In addition, “when the probability variation lottery is not determined to be winning” means that the probability variation lottery is not won as a result of executing the probability variation lottery, and the case where the probability variation lottery is not performed. In either case.

Here, the “time limit” means the time from the start to the end of the game such as reach fluctuation display, big hit fanfare, a game (special game) in which the variable winning device is opened in a pattern with a short opening time, or these times And a set time measured from a predetermined timing (launch instruction timing) (for example, a firing instruction can be performed during reach and 30 seconds can be set as the time limit from the instruction). In addition, a time limit may be set by adding a plurality of times, such as the time from the start to the end of reach fluctuation display by adding the time of reach fluctuation display and the time of the big hit fanfare.
The “predetermined time or longer” may be set to a time equal to or shorter than the “time limit”. For example, the time limit can be set to 30 seconds and the predetermined time can be set to 20 seconds. In this case, if the firing is not started within 10 seconds after the time limit is started, an input for a predetermined time or longer is not recognized. Moreover, if the launch is started immediately after the time limit starts counting, an input of a predetermined time or more can be achieved with a remaining time of 10 seconds. Moreover, even if it is a case where discharge | release is interrupted in the middle of the time limit, the integration time of the discharge | release time before and behind interruption should just be more than predetermined time.

In order to achieve the above object, in another invention 3, in addition to the configuration of the other invention 2, either the case where the probability variation lottery unit determines to win or the case where the probability variation lottery unit does not determine to win. Even in this case, by setting the opening / closing pattern of the variable winning device to the same opening / closing pattern, it is determined whether the lottery probability after the end of the special game is high or low. It is a gaming machine that is difficult to recognize depending on the pattern,
The same opening pattern, by being open time is set shorter for the variable winning device compared to other closing pattern input sphere game ball is a difficult opening pattern, the time limit, the identification and execution time variable display of the symbols, wherein said variable winning devices are set across the opening and closing process execution time for executing the opening and closing process in the same opening pattern.

According to another invention 3, among the opening / closing patterns of the variable winning device, when opening / closing the variable winning device according to an opening / closing pattern in which the opening time is short (the opening time is instantaneous) and it is difficult to enter the game ball, By setting the opening / closing process execution time of the opening / closing pattern as the time limit, it is possible to prevent the player from stopping and to improve the operating rate of the gaming machine. Fortunately, if a game ball enters the variable winning device, the player can also obtain a prize ball. Therefore, setting the opening / closing process execution time as a time limit is This leads to an improvement in the operating rate of the machine and also leads to a chance of winning a prize ball from the player side, which is preferable in that the launched game ball does not become a mere waste ball.

  In addition, in the game after the end of the opening / closing process execution time, it becomes a gaming state in which it is difficult to recognize whether it is in a high probability state or a low probability state. , Games can be clarified. In other words, the player can recognize the degree of possibility of the high probability state by receiving a certain notification, and can prevent the situation of starting the game in a completely unknown state as much as possible.

  According to the present invention, when the player performs the launch operation as instructed, the player is given a benefit by the notification means, thereby effectively preventing the player from stopping and operating the gaming machine. The rate can be improved.

In the present embodiment, a large liquid crystal display device is used as the effect display device 25, and various effect displays are performed in the display area of the effect display device 25.

  The big winning device 33 is arranged below the central device 24 in the game area 21. The first decoration device 50 is arranged on the left side of the big prize device 33 in the game area 21, the second decoration device 60 is arranged on the right side of the big prize device 33 in the game area 21, and the decoration devices 50, 60 are so-called side. Make up decorations. Further, the first winning device 34 is integrated with the left winning holes 34 and 35, and the second winning device 60 is integrated with the right winning ports 36 and 37.

  The normal symbol operating gate 27 is provided on the left side of the central device 24. Inside the normal symbol operating gate 27, a normal symbol operating gate detection switch 27s (see FIG. 3) for detecting the passage of the game ball is provided. When the game ball passes through the normal symbol operating gate 27, the normal symbol starts to fluctuate.

  The start port 28 is provided below the central position of the central device 24. The start port 28 is a first start port provided on the upper side, in which two entrance ports formed with a game ball receiving port for receiving a game ball flowing down on the surface of the game board 20 are arranged side by side in the vertical direction. 28a and a second start port 28b provided on the lower side. The first start port 28a and the second start port 28b correspond to the start winning device of the present invention.

  The first start port 28a is a normal start port configured as a fixed start port in which the size of the game ball receiving port does not change and the possibility of entering the game ball is constant. It is possible. On the other hand, the second start port 28b is a so-called tulip type and has a pair of wing pieces on the left and right, and the upper end gap between the pair of wing pieces serves as a game ball receiving port. The pair of wing pieces are each opened and closed by tilting in the left-right direction. With this opening and closing action, the second start port 28b is the size of the game ball receiving port of the pair of wing pieces. It is configured as a variable start port in which changes. The second start port 28b is in a state where the possibility of entering a ball is high when the pair of blade pieces are opened, and the state where the possibility of entering is low (the ball cannot be entered) when the pair of blade pieces is closed. Including the state). When the normal symbol is stopped and displayed as a combination of symbols, the pair of wing pieces are opened to expand the game ball receiving port of the second start port 28b, and the second start port 28b is a normal electric accessory. Function as.

  Inside the start port 28, a start port entrance detection switch 28s (see FIG. 3) for detecting the entrance of a game ball, and a start port solenoid 28c (see FIG. 3) for operating a pair of wing pieces. Is provided. When the pair of wing pieces are opened to the left and right, the size of the game ball receiving port of the second start port 28b is enlarged from the normal time, and the second start port 28b has a possibility of entering a game ball. It becomes an open state that becomes larger. On the other hand, when the pair of wing pieces are erected, the size of the game ball receiving port of the second start port 28b is slightly larger than the diameter of the game ball (one game ball can pass). The second start port 28b is in a normal state (closed state) in which the possibility of entering a game ball is reduced (or entry is impossible). As the game balls enter the start ports 28a and 28b, the special symbols described later start to fluctuate.

  The big prize device 33 is disposed below the start port 28. Here, the special winning device 33 includes a special winning opening 33a opened in a belt shape, an opening / closing plate 33b for opening / closing the special winning opening 33a, and a large winning opening solenoid 33c (for operating the opening / closing plate 33b). 3) and an incoming ball detection switch 33s (see FIG. 3) for detecting an incoming game ball.

  A left winning opening 34 and 35 and a right winning opening 36 and 37 are provided on the upper left side and the upper right side of the big winning device 33. Each of these winning openings is provided with a winning opening entering detection switch (not shown).

  The first decorative member 50 is provided with a plurality of LEDs, and a combination of these LEDs constitutes a normal symbol display portion 51, a general symbol hold display portion 52, and a special symbol hold display portion 53. Similarly, the second decorative member 60 is provided with a plurality of LEDs, and a special symbol display unit 61 is configured by a combination of these LEDs.

  The normal symbol display part 51 is comprised from one LED, and a normal symbol is displayed by this LED. In the normal symbol display unit 51, the normal symbol variation display and stop display are performed. In the normal symbol display unit 51, the normal symbol starts to change when the game ball passes through the normal symbol operating gate 27, and after a predetermined time has passed, the normal symbol hits and stops display in the normal symbol display mode or the dismissed normal symbol display mode. Is done. Then, when the normal symbol is stopped and displayed in the preset normal symbol display mode, the second start port 28b is opened for a predetermined time (for example, 0.1 second).

  In this embodiment, a normal symbol success / failure random number is provided, and this normal symbol success / failure random number is acquired when the game ball passes through the normal symbol operation gate 27, and activates the second start port 28b. It is used to determine whether or not a normal symbol is appropriate. The normal symbol success / failure random number is set in advance with a hit value, and the normal symbol success / failure determination random number acquired at the timing when the game ball passes the normal symbol operation gate 27 matches the win value. Determined. When it is determined to be a winning, the normal symbol that is stopped and displayed on the normal symbol display unit 51 is determined as the display mode of the winning normal symbol. On the other hand, when it is determined to be out (when the acquired normal symbol success / failure random number does not match the winning value), the normal symbol stopped and displayed in the normal symbol display unit 51 is determined as the display mode of the out of normal symbol. Is done. Note that the normal symbol success / failure determination and the normal symbol stop symbol determination are performed by a CPU 200a of the main control board 200 described later.

  Here, normal symbol holding will be described. The normal symbol hold display section 52 displays the normal symbol hold number, and the number of game balls that have passed through the normal symbol operation gate 27 can be held up to the maximum hold number (four in this embodiment). Each time the next normal symbol win / fail determination is made and the normal symbol variation display is started, the number of unstarted times (the number of reservations) is consumed, and the number of normal symbol reservations is decreased by one. The general-purpose hold display unit 52 includes two LEDs, and can display the number of holds with an upper limit of four by combining turning off, lighting, and blinking of the two LEDs. The normal symbol holding and holding digest are performed by a CPU 200a of the main control board 200 described later. Along with the holding of the normal symbol, the random number for determining whether or not the normal symbol is stored is stored in a predetermined area of the RAM of the main control board 200.

  Next, the special symbol will be described. The special symbol display unit 61 is composed of seven LEDs, and special symbols are displayed by these LEDs. Each LED constituting the special symbol display unit 61 can be turned on and off, and a plurality of special symbol display modes can be displayed by a combination of turning on and off the LEDs. Of the special symbol combinations displayed by the seven LEDs, a specific combination is set as a winning symbol (big hit symbol or small hit symbol), and a combination other than the specific combination is set as an outlier symbol. Yes. In this embodiment, the special symbol variation display is performed by blinking display in which each LED is repeatedly turned on and off. In the special symbol display unit 61, when the game ball enters the start port 28, the special symbol starts to fluctuate, and after the predetermined time has elapsed, the special symbol is stopped and displayed as a winning symbol or a missing symbol. In addition, as a variation pattern which prescribes | regulates the variation aspect of a special symbol, the variation pattern for probability variation, the variation pattern for time reduction, and the variation pattern for normal time are provided according to the game state mentioned later.

  In this embodiment, a special symbol success / failure determination random number that is acquired when a game ball enters the start opening 28 and is used for determining whether or not to generate a jackpot game is used. Yes. Further, a random number for lottery lottery used for small lottery symbol lottery for determining whether or not to generate a small hit game is provided. Furthermore, a symbol determining random number for determining a stop symbol of the special symbol is provided. Along with the game ball entering the start opening 28, special design success / failure random numbers, small lottery random numbers and design determination random numbers are acquired, and these various random numbers are stored in a predetermined area of the RAM of the main control board 200. Is remembered.

  Here, the holding of special symbols will be described. The special symbol hold display section 53 includes two LEDs, and can display the number of holds with an upper limit of four by combining turning off, lighting, and blinking of the two LEDs.

  The number of game balls that have entered the starting port 28 can be reserved until the maximum number of reservations (four in this embodiment) is reached as the number of special symbol reservations. The special symbol holding number corresponds to the number of random numbers (stored number) acquired every time a game ball enters the start port 28 and stored in a predetermined area of the RAM of the main control board 200. The number of special symbol reservations is digested each time a special symbol success / failure determination is performed and the variation display of the special symbol is started, and decreases by one. Note that special symbols are reserved and digested by a CPU 200a of a main control board 200 described later.

  The special symbol success / failure determination is performed when the special symbol starts to change. The special symbol success / failure determination random number is preliminarily set with a winning value for determination of success / failure. When the special symbol success / failure determination random number matches the winning value, it is determined to be a big hit, and the special symbol display unit 61 is stopped and displayed. The special symbol is determined to be a jackpot symbol (probable variation jackpot symbol or normal jackpot symbol). If the special symbol success / failure random number does not match the winning value, a small winning lottery for determining whether or not to generate a small hitting game is performed, and if the lottery result is a small winning, a special symbol display section At 61, the special symbol to be stopped and displayed is determined as the small hit symbol. On the other hand, when the result of the special symbol success / failure determination is not a big hit and the result of the small hit lottery is not a big hit, the special symbol that is stopped and displayed on the special symbol display unit 61 is determined to be a lost symbol. The Note that the special symbol success / failure determination, determination of the special symbol variation pattern, and determination of the special symbol stop symbol are performed by a CPU 200a of the main control board 200 described later. The CPU 200a of the main control board 200 that executes the big hit lottery and the small hit lottery corresponds to the lottery means of the present invention.

  Next, the jackpot game will be described. When the special symbol stopped and displayed on the special symbol display unit 61 is a big hit symbol (when the result of the special symbol determination is a big hit), the CPU 200a of the main control board 200 is a big hit that is relatively advantageous to the player. Start the game. The jackpot game is started by setting the jackpot game flag to ON. The big hit game operates the prize winning device 33, in other words, opens and closes the prize winning opening 33a (the number of times of opening and closing may be one or more times). The player 200 is provided with a benefit for entering the game ball, and the CPU 200a of the main control board 200 corresponds to the special game execution means of the present invention.

  During the big hit game, the big prize device 33 is operated, and a predetermined number of prize balls (for example, 15 prize balls for one prize) according to the number of game balls entered into the big prize opening 33a. Will be paid out. Specifically, at the start of the big hit game, the big prize opening device (special electric accessory) 33 is continuously operated, and the big prize opening opening / closing operation for switching the big prize opening 33a between the open state and the closed state is continuously performed a plurality of times. Done. With the start of the operation of the big prize device 33, the big prize opening 33a in the closed state is opened. This open state is ended when a predetermined end condition is established, and the open special winning opening 33a is closed. As a predetermined end condition, when the opening time of the big winning opening 33a reaches a predetermined time (30 seconds or 0.2 seconds in this embodiment), or the number of game balls that have entered the opened big winning opening 33a is It may be when the predetermined number (10 in this embodiment) is reached.

  When it is assumed that one round is from the start to the end of the open state of the big winning opening 33a, the big hit game is ended by performing a predetermined number of rounds. In the grand prize winning device 33, after the opening of the big prize winning opening 33a is completed, that is, after a predetermined time (for example, 2 seconds) has passed since the big winning prize opening 33a is closed, the big winning prize opening 33a is again opened. Round begins. The opening / closing operation of the grand prize opening 33a, in which the opening and closing of the big prize opening 33a is one round, is repeated until the predetermined maximum number of continuous rounds (15 rounds or 2 rounds in this embodiment) is completed. Is done.

In the gaming machine 1 of the present embodiment, two types of jackpot games are provided depending on the type of jackpot symbol. When the big hit symbol is a normal big hit symbol or a probable variation big hit symbol, that is, when the result of the special symbol success / failure determination is a normal big hit or a probable variation big hit symbol, a first big hit game is generated. When the big hit symbol is the specific big hit symbol, that is, when the result of the special symbol hit / fail judgment is a specific big hit among the probability variation big hits, the second big hit game is generated.
In the second jackpot game, the number of times the maximum winning opening 33a is opened (the maximum number of consecutive rounds) is set smaller than that in the first jackpot game, and the opening time of the big winning opening 33a is set shorter. In other words, the first big hit game is a game state in which a large amount of game balls enter the big winning opening 33a and a lot of prize balls are paid out. In the second big hit game, the game balls enter the big winning opening 33a. There is a very low possibility of a ball (because the big prize opening is only opened for a moment), and it is a gaming state that does not substantially involve award ball payout. In this embodiment, the maximum number of consecutive rounds of the first big hit game is 15 rounds and the opening time of the big winning opening 33a is set to 30 seconds, and the maximum number of consecutive rounds of the second big hit game is 2 rounds and the big winning mouth is set. The opening time of 33a is set to 0.2 seconds. Hereinafter, the first jackpot game is also referred to as a 15R jackpot game, and the second jackpot game is also referred to as a 2R jackpot game. The opening / closing pattern of the big winning opening 33a related to the second jackpot game corresponds to an opening / closing pattern in which it is difficult to enter the game ball of the present invention.

  In the gaming machine of this embodiment, after the big hit game is finished, a specific game (so-called short-time game and probability variable game) in which the variable time shortening function, the open time extending function, and the probability varying function are activated is started. Multiple types of jackpots are set in the special symbol success / failure determination. If the result of the special symbol success / failure determination is a normal jackpot (the special symbol stop symbol is a normal jackpot symbol), after the jackpot game ends, In the case where the result of the special symbol success / failure determination is a probable big hit (the special symbol stop symbol is a probable big hit symbol), the probable variation game is started after the big hit game ends. The variable time shortening function, the opening time extending function, and the probability varying function are activated by setting the fluctuation shortening flag, the opening extension flag, and the probability changing flag to ON, respectively. The probability variation function corresponds to the lottery probability variation means of the present invention.

  When the special symbol success / failure determination is a normal jackpot (the special symbol stop symbol is a normal jackpot symbol), after the jackpot game is over, a variable time shortening function and an opening time extending function for extending the opening time of the second start port 28b are provided. The operation starts and the short-time game is started. The variation time shortening function and the opening time extension function are activated or stopped by the control of the CPU 200a of the main control board 200. The variation time shortening function includes a normal symbol variation time shortening function for shortening the ordinary symbol variation time. And a special symbol variation time shortening function for shortening the special symbol variation time. The fluctuation time shortening function and the opening time extension function operate after the big hit game is finished until the next big hit game is started, or until the number of fluctuations of the special symbol reaches a predetermined number (100 times in this example). .

When the special symbol success / failure determination is a probability variation jackpot (the special symbol stop symbol is a probability variation jackpot symbol or a specific jackpot symbol), after the jackpot game ends, the probability variation function starts to operate and the probability variation game starts. The probability variation game is realized by the control of the CPU 200a of the main control board 200. In this probability variation game, the probability of changing (improving) the probability of the special symbol success / failure determination, that is, the probability that the special symbol is stopped and displayed with the big hit symbol. The variation function is activated. The probability variation function operates after the jackpot game is over until the next jackpot game is started.
In the probability variation game, the type of probability variation jackpot (whether the stop symbol is a probability variation jackpot symbol or a specific jackpot symbol), the gaming state when the probability variation jackpot is reached (probability variation gaming state, short-time gaming state, normal game) It is possible to set whether the variable time shortening function and the open time extending function operate or not. The CPU 200a of the main control board 200 corresponds to the probability variation lottery means of the present invention, and executes a lottery to determine whether the lottery probability is high or low by determining the big hit symbol by random lottery. Yes.

  In addition, the probability variation function is activated among the promising big hits, and the operating state of the fluctuation time shortening function and the open time extension function when the big hit is reached (when the big hit symbol is stopped and displayed) is maintained even after the big hit game ends. The probable big hit is called a special big hit (the special symbol is a special big hit symbol). In other words, when the big hit (when a specific big hit symbol is stopped and displayed), if the variable time reduction function and the release time extension function are activated, the variable time reduction function and release after the big hit game ends. Activate the time extension function. On the other hand, if the fluctuation time shortening function and the opening time extension function are not activated when the big hit is made, the fluctuation time shortening function and the opening time extension function are not activated even after the big hit game is finished.

  More specifically, when a jackpot game is generated with a specific jackpot symbol (a specific jackpot is reached), the probability variation function is activated after the 2R jackpot game ends with a short operation time of the big winning opening 33a and a small number of operations. In addition, the operating state of the open time extension function when the big hit game is generated is maintained. In this case, it is difficult for the player to recognize the start of the operation of the probability variation function because the probability variation function starts operating without changing the operation state of the start port 28 (the lower start port 28b) visible to the player. Can be. Thus, the state in which it is difficult for the player to recognize that the probability variation function is operating is called “latency probability variation” or “internal probability variation”. Further, the second big hit game that causes the latent probability change is also referred to as “latent big hit game”.

  Next, the small hit game will be described. When the special symbol stopped and displayed on the special symbol display unit 61 is a small hit symbol (when the result of the small hit lottery is a small bonus), the CPU 200a of the main control board 200 starts the small hit game. The small hit game is started by setting the small hit game flag to ON. The small hit game is to operate the big winning device 33. In the small hit game, the big prize device 33 operates in the same manner as the second big hit game described above. In other words, in the small hit game, the large winning opening 33a is configured to be opened twice for 0.2 seconds, and the possibility that a game ball enters the large winning opening 33a is very low, so that the payout of the winning ball is substantially reduced. It is in a gaming state that does not accompany. The opening / closing pattern of the big winning opening 33a related to the small hit game corresponds to an opening / closing pattern in which it is difficult to enter the game ball of the present invention. In addition, after the small hit game ends, the operating state of the open time extension function when the small hit game is generated (when the small hit symbol is stopped and displayed) is maintained.

  In the small hit game, since the operation of the second big hit game and the big prize device 33 is the same mode, the player can open and close the big winning opening 33a twice in a short time (a big winning opening opening pattern in the second big hit game) ) Cannot be discriminated whether the second big hit game or the small hit game has occurred. For this reason, it is possible to make it more difficult to recognize whether or not the probability variation function is activated after the operation of the big winning device 33 is finished (after the second big hit game or the small hit game is finished). Thus, the presence of the small hit game can make the latent probability change more effective.

  Next, the effect symbols displayed on the effect display device 25 will be described. In the display area of the effect display device 25, an effect symbol display unit 25a for displaying an effect symbol, a lottery probability informing unit 25b for informing whether the lottery probability of the big hit lottery is high probability or low probability, and the contents instructed by the firing instruction means And a firing time display unit 25d for displaying the firing time actually fired by the player in accordance with the firing instruction. The effect symbol of the effect symbol display unit 25a is displayed in conjunction with the change display and stop display of the special symbol of the special symbol display unit 61. The effect symbol display unit 25a corresponds to the symbol display unit of the present invention, and the lottery probability notification unit 25b corresponds to the notification unit of the present invention. In the present embodiment, the effect display device 25 serves as both symbol display means and notification means.

The effect symbol display unit 25a is composed of three symbol display areas including a left symbol display area where a left symbol is displayed, a middle symbol display area where a middle symbol is displayed, and a right symbol display area where a right symbol is displayed. Yes. Each symbol display area has a symbol variation direction set in a direction substantially orthogonal to the arrangement direction of these display areas, in this case, in the vertical direction (vertical direction). Each symbol display area can display symbols consisting of “1” to “9”. Of the display screen of the effect display device 25, the portion excluding the effect symbol display unit 25a is a background display area in which various background symbols including characters, figures, symbols, characters, and the like are displayed.
The lottery probability notification unit 25b is provided in a part of the display area of the effect display device 25, and a display area for notifying the possibility that the jackpot lottery probability is high is configured. Further, if the notification display is not a predetermined certainty change confirmation effect (such as “100%” display or “confirmation” display), the possibility of a latent certainty change is notified. Details will be described later.

  The effect symbol starts to be displayed when the special symbol starts to be changed. When the special symbol is stopped and displayed in any of the symbols, the effect symbol is stopped and displayed in accordance with the stop symbol of the special symbol. In the production design, the combination of even symbols with the same three digits corresponds to the normal big hit symbol of the special symbol, and the combination of odd symbols with the same three digits corresponds to the probabilistic big hit symbol of the special symbol, such as “1, 2, 3”, etc. Specific combinations other than the winning symbol, such as a combination of an ordered number of numbers, a combination of an ordered number of odd numbers such as “1, 3, 5”, or a combination of out of reach such as “4, 5, 4”. Chance symbols (so-called chance eyes) that are out-of-line symbols (design combinations that are not the same in 3 digits) correspond to special big hit symbols or small hit symbols for special symbols, and combinations of other symbols correspond to special symbol out-of-band symbols ing. This chance symbol corresponds to the same type of identification information of the present invention.

  The determination of the variation pattern (effect pattern) of the effect symbol and the stop symbol is performed by the CPU 260a of the sub-control board 260 based on the change pattern designation command transmitted from the CPU 200a of the main control board 200. Here, the variation pattern designation command transmitted from the CPU 200a of the main control board 200 indicates the variation pattern of the special symbol. Specifically, the variation content of the special symbol, the contents of the representation such as the presence / absence of the reach effect, etc. Show. The CPU 200a of the main control board 200 determines the variation pattern of the special symbol at random (by random number lottery) according to the determination result of the special symbol. Then, based on the variation pattern of the special symbol determined by the CPU 200a of the main control board 200, the CPU 260a of the sub control board 260 determines the effect pattern of the effect symbol displayed on the effect symbol display unit 25a.

  The CPU 200a of the main control board 200 selects the variation pattern table for probability variation during the probability variation game (including the latent probability variation game) as the variation pattern table used when determining the variation pattern of the special symbol, and uses the time variation for the time-short game. A variation pattern table is selected, a normal variation pattern table is selected in a normal game that is neither a probability variation game nor a short-time game, and a specific variation pattern is determined from the selected variation pattern table. In this embodiment, a special variation pattern is provided as a special symbol variation pattern in addition to the probability variation variation pattern, the time variation variation pattern, and the normal variation pattern described above.

  Here, among the above-mentioned variation pattern tables, the “probability variation pattern table”, “temporal variation pattern table”, and “normal variation pattern table” indicate whether the special symbol variation start / failure determination result or special diagram hold Various fluctuation patterns (fluctuation times) are preset according to the number (the number of lottery rights held for special symbol determination). For example, in the “normal variation pattern table” used when the game state is “normal state (normal game)”, the success / failure determination result at the start of the variation of the special symbol is “out”, and the number of special figure hold is “Plural deviation variation patterns with a variation time of 3 to 7 seconds” that can be selected in the case of “3” or “4”, and “2” or “1” that can be selected when the number of special figure reservations is “2” or “1”. Special symbols such as “plurality fluctuation patterns with fluctuation times of 10 to 60 seconds” and “multiple hit fluctuation patterns with fluctuation times of 40 to 120 seconds” that can be selected when the determination result is “winning” Various variation patterns according to the determination result at the start of variation and the number of special figure reservations are preset.

  On the other hand, in the “special variation pattern table”, if the determination result is “out” regardless of the number of holdings at the start of variation of the special symbol and the game state (normal game, short-time game, probability variation game, latent probability variation game) “Change time variation pattern of 30 seconds” that can be selected, and “Change time of 40 seconds” that can be selected when the success / failure determination result is “Win” regardless of the number of holdings at the start of special symbol change and the game state A plurality of hit variation patterns of ˜120 seconds ”are set in advance. There is only one type of outlier variation pattern set in this “special variation pattern table” with a fixed (unified) variation time, and this outlier variation pattern is a special variation pattern.

  In a predetermined period from the end of the second jackpot game (2R jackpot game), the “special variation pattern table” is used, and the special variation pattern is determined as a common variation pattern. Therefore, the CPU 200a of the main control board 200 sets the special variation flag to ON and the special variation flag to ON for a predetermined period from the end of the small hit game or the second big hit game (2R big hit game). During this period, the special variation pattern table is selected. The special variation flag is set to ON in response to the end of the second big hit game or the small hit game, in other words, in response to the end of the opening / closing operation of the big winning opening 33a. In the present embodiment, the “predetermined period” during which the special variation pattern table is selected is from the end of the second big hit game (2R big hit game) or the small hit game until the number of changes in the special symbol reaches 30 times. ing. That is, the special variation pattern table is selected when the result of the special symbol winning / decision determination after the end of the second big hit game (2R big hit game) or the small hit game is “disconnected” for 30 consecutive times. The “predetermined period” ends. Then, the CPU 260a of the sub control board 260 that has received the variation pattern designation command for designating the special variation pattern is configured to execute a special effect that improves the player's expectation for the occurrence of the big hit.

Next, the operation of the gaming machine 1 of the present embodiment will be described based on a flowchart. FIG. 4 shows an example of a main job executed by the CPU 200a of the main control board 200 based on a program stored in the ROM. The main job shown in FIG. 4 executes the power-on process S100, and then starts the game start process S200, the normal symbol game process S300, the normal electric game game process S400, the special symbol game process S500, the notification process S800, and the special electric game object. Each step of the game process S600 is repeatedly executed every time the timer is reset. In the power-off generation process S700, when a power-off occurs due to a power failure or the like, the used registers and stack pointers are saved, the payout motor is stopped, and so on, and when a system reset occurs, the process proceeds to the power-on process S100. It has become.

  The power-on process S100 is performed when the power is turned on and when the power is restored after the power is cut off. When the power is turned on, a RAM initialization process or the like is performed, and when the power is turned off, the game state is restored. The return setting is performed. In the game start process S200, detection of various switch states, update of various random numbers, prize ball control, and the like are performed.

  In the normal symbol game processing S300, first, whether or not the normal symbol is determined is determined, and the normal symbol display unit 51 (see FIG. 2) determines whether the normal symbol is to be stopped and displayed as a winning symbol or as a stop symbol. To do. Next, after setting the normal symbol fluctuation display time, the normal symbol fluctuation display is started. When the variable display time elapses, the normal symbol is stopped and displayed with the determined symbol, and when the normal symbol hit symbol is stopped and displayed, the operation of the ordinary electric accessory is started. In the normal symbol game process, the normal symbol variation display and the stop display are performed as described above, and when the normal symbol is stopped and displayed as the winning symbol, the second start port 28b is activated. When the second start port 28b is actuated, the pair of blade pieces open to the left and right, and the second start port 28b is opened.

  In the ordinary electric accessory game process S400, it is determined whether or not the opening time for maintaining the second start port 28b in the open state has elapsed. If the open time has not elapsed, the second start port 28b is defined. It is determined whether or not a winning number has been won. When it is determined that the predetermined number of winnings has been won at the second starting port 28b in the open state, or when it is determined that the opening time of the second starting port 28b in the open state has elapsed, a pair of The blade piece is closed and the second start port 28b is in the normal state.

  Next, the special symbol game process S500 will be described based on the flowchart of FIG. First, it is determined whether or not the start port 28 has been won (S501). If it is determined that the start port 28 has been won (S501: YES), the operation of the special symbol display unit 61 (see FIG. 2) is suspended. It is determined whether or not the number is less than 4 (S502). As a result, if it is determined that the number of special symbol reservations is less than 4 (S502: YES), a special symbol success / failure determination random number and a symbol determination random number are acquired, and a predetermined area of the RAM of the main control board 200 is obtained. (S503).

  Next, it is determined whether or not the big hit game or the small hit game is being played (S504). As a result, if it is determined that the game is a big hit game or a small hit game (S504: YES), the special symbol game process is terminated, and if it is determined that the big hit game or the small hit game is not being executed ( S504: NO), it is determined whether or not the special symbol is changing (S505). As a result, when it is determined that the special symbol is changing (S505: YES), the process proceeds to S511 described later, and when it is determined that the special symbol is not changing (S505: NO). Then, it is determined whether or not it is during the special symbol stop display time (S506). If it is determined that it is during the special symbol stop display time (S506: YES), the process proceeds to S515 described later, and if it is determined that it is not during the special symbol stop display time (S506: NO). ), It is determined whether or not the number of special symbol hold is zero (S507).

  As a result, if it is determined that the number of special symbol hold is zero (S507: YES), the special symbol game process is terminated as it is, and if it is determined that the number of special symbol hold is not zero (S507: NO), the special symbol success / failure determination random number stored first in the RAM is read (S508).

  Next, special symbol success / failure determination processing is performed (S509). Here, the special symbol success / failure determination processing S509 will be described based on the flowchart of FIG.

  First, it is determined whether or not the probability variation flag is ON (S509a). If the probability variation flag is ON (S509a: YES), the probability variation game success / failure determination table is selected (S509b), and the probability variation flag is OFF. If this is the case (S509a: NO), the normal game success / failure determination table is selected (S509c).

  Next, it is determined whether or not the result of the big hit determination performed using the special symbol determination random number read in S508 and the determination table selected in S509b or S509c is a big win (S509d). As a result, when it is determined that the result of the jackpot winning / failing determination is a jackpot (S509d: YES), the symbol determination random number stored in the RAM is read (S509e), and the symbol determination random number is used to determine the jackpot symbol. Determine (S509f).

  On the other hand, when it is determined that the result of the big hit determination is not big hit (S509d: NO), the small hit lottery is performed (S509g), and it is determined whether the lottery result is the small hit (S509d). This small hit lottery is performed using the random numbers for the small hit lottery described above, and is performed in the same manner as the determination of whether or not a special symbol is successful (big hit lottery). When it is determined that the lottery result is a small hit (S509: YES), a small hit symbol is determined (S509i), and when it is determined that the lottery result is not a small hit (S509: NO), The off symbol is determined (S509j). In this embodiment, the small hit symbol and the off symbol are determined as predetermined symbols, but these may be determined by random number lottery.

  Next, returning to the special symbol game process of FIG. 5A, a symbol variation start process is performed (S510). Here, the symbol variation start processing S510 will be described based on the flowchart of FIG.

  First, when the gaming state determined by the success / failure determination process of S509 is a big hit (S510a: YES), the big hit hour variation pattern table distribution process is executed (S510b), and when the big hit is a small hit (S510c). : YES), the small-hit fluctuation pattern table distribution process is executed (S510d), and even if the big hit is not a small-hit, that is, it is out of place (S510c: NO), the fluctuation pattern table distribution process at the time of loss is executed. (S510e).

  Next, the big hit time fluctuation pattern table distribution processing S510b, the small hit time fluctuation pattern table distribution processing S510d, and the loss time fluctuation pattern table distribution processing S510e will be described. Since these fluctuation pattern table distribution processes are the same in the big hit, small hit and out, respectively, here, only the big hit fluctuation pattern table distribution process S510b is based on the flowchart of FIG. explain.

  First, it is determined whether or not the special fluctuation flag is ON (S5101). If the special fluctuation flag is ON (S5101: YES), a special fluctuation pattern table is set (S5102). If the special variation flag is not ON (S5101: NO), it is determined whether or not the probability variation flag is ON (S5103). If the probability variation flag is ON (S5103: YES), the variation pattern for probability variation is determined. A table is set (S5104). If the probability variation flag is not ON (S5103: NO), it is determined whether or not the variation shortening flag is ON (S5105). If the variation shortening flag is ON (S5105: YES), the variation for time reduction is determined. A pattern table is set (S5106). If the fluctuation shortening flag is not ON (S5105: NO), the normal fluctuation pattern table is set (S5107). As described above, in the variation pattern distribution process, when the special variation flag is ON, the special variation pattern table is set regardless of the gaming state (normal game, short-time game, probability variation game, latent probability variation game) When the variation flag is not ON, a variation pattern table corresponding to the gaming state is set.

  Next, returning to the symbol variation start process of FIG. 7, a variation pattern determining random number is acquired (S510f), and the variation pattern of the special symbol is determined using the variation pattern table set in any of S510b, S510d, and S510e. (S510g). Then, the special symbol display unit 61 starts to display the variation of the special symbol (S510h), and transmits the variation pattern designation command and the special symbol stop information designation command to the sub-control board 260 (S510i). Receiving these commands, the sub-control board 260 starts effect display variation display (effect display) on the effect display device 25.

  Next, it is determined whether or not the special variation flag is ON (S510j). As a result, when the special variation flag is not ON (S510j: NO), the symbol variation start process is terminated, and when the special variation flag is ON (S510j: YES), the special variation counter is decremented by 1 ( S510k). The special variation counter is for counting a period during which the special variation pattern table is selected, and is set in S609i described later after the second big hit game or the small hit game is completed.

  Then, it is determined whether or not the special variation counter is zero (S510l). If the special variation counter is not zero (S510l: NO), the symbol variation start process is terminated as it is, and the special variation counter is zero. In this case (S510l: YES), the special variation flag is set to OFF (S510m). Thereby, the period during which the special variation pattern table is selected ends, and thereafter, the variation pattern table corresponding to the gaming state is selected.

  Next, returning to the special symbol game process of FIG. 5A, if it is determined in S505 that the special symbol is changing (S505: YES), whether or not the special symbol change time has elapsed. Is determined (S511). As a result, when it is determined that the variation time of the special symbol has not elapsed (S511: NO), the special symbol game process is terminated as it is and it is determined that the variation time of the special symbol has elapsed. (S511: YES), the special symbol change is stopped (S512), a symbol stop command is transmitted to the sub-control board 260 (S513), and the special symbol stop symbol display time is set (S514). Receiving the symbol stop command, the sub control board 260 stops the effect symbol variation display on the effect display device 25.

  Next, it is determined whether or not the special symbol stop display time has elapsed (S515). As a result, when it is determined that the special symbol stop display time has not elapsed (S515: NO), it is determined that the special symbol game processing is terminated and the special symbol stop display time has elapsed. If it is determined (S515: YES), it is determined whether or not the special symbol stop symbol is a big hit symbol (S516 in FIG. 5B). As a result, when it is determined that the stop symbol of the special symbol is a jackpot symbol (S516: YES), it is determined whether or not it is a specific jackpot symbol (S517).

  As a result, if it is not a special big hit symbol (S517: NO), the 15R big prize opening pattern is set (S518), and if it is a special big hit symbol (S517: YES), the 2R big prize opening is opened. A pattern is set (S519). Then, the jackpot game flag is set to ON and the jackpot game is started (S520). The 15R big prize opening pattern is the opening pattern of the first big prize game big prize opening 33a, and the 2R big prize opening pattern is the opening pattern of the second big prize game big prize opening 33a. is there.

  Next, it is determined whether or not the probability variation flag is ON (S521). As a result, if it is determined that the probability variation flag is ON, that is, if the probability variation game is in progress (S521: YES), the probability variation flag is set to OFF (S522), and the variation shortening flag is set to OFF ( S523), the release extension flag is set to OFF (S523). As a result, along with the start of the big hit game, the probability variation function, variation time shortening function, and open time extension function are deactivated.

  On the other hand, if it is determined in the determination processing of S521 that the probability variation flag is not ON (S521: NO), it is determined whether or not the fluctuation shortening flag is ON (S525). As a result, if it is determined that the fluctuation shortening flag is ON, that is, if the game is in a short time game (S525: YES), the fluctuation shortening flag is set to OFF (S523), and the release extension flag is set to OFF. (S523). Thereby, with the start of the big hit game, the variable time shortening function and the open time extending function are deactivated. If it is determined that the fluctuation shortening flag is not ON, that is, if a normal game is being played (S525: NO), the special symbol game process is terminated as it is.

  Next, in the determination process of S516, when it is determined that the special symbol stop symbol is not a big hit symbol (S516: NO), it is determined whether or not the special symbol stop symbol is a small hit symbol (S526). ). As a result, when it is determined that the stop symbol of the special symbol is not a small hit symbol (S526: NO), the process proceeds to S529, and when the stop symbol of the special symbol is determined to be a small hit symbol. (S526: YES), the small winning big opening opening pattern is set (S527), the small hit game flag is turned on, and the small hit game is started (S528). The small winning big winning opening pattern is an opening pattern of the small winning game big winning opening 33a, which is the same as the second big winning game.

  Next, it is determined whether or not the fluctuation shortening flag is ON (S529). As a result, when it is determined that the variation shortening flag is not ON (S529: NO), the special symbol game process is terminated as it is, and when it is determined that the variation shortening flag is ON (S529: NO), the variation The shortening counter is decremented by 1 (S530), and it is determined whether or not the fluctuation shortening counter has become zero (S531). The fluctuation shortening counter is for counting the operating period of the fluctuation time shortening function and the opening time extending function, and is set in S609m to be described later after the big hit game generated due to the normal big hit symbol.

  As a result, if it is determined that the fluctuation shortening counter is not zero (S531: NO), the special symbol game process is terminated as it is, and if it is determined that the fluctuation shortening counter is zero (S531: YES). ), The fluctuation shortening flag is turned OFF (S532), and the open extension flag is turned OFF (S533). As a result, when the number of changes in the special symbol reaches 100 after the start of the short-time game, the variable time shortening function and the open time extending function are deactivated.

  Next, the special electric accessory game process S600 will be described based on the flowchart of FIG. First, it is determined whether or not a winning game is in progress (during a big hit or a small hit game) (S601). Whether or not the winning game is being played can be determined based on whether or not either the big hit game flag or the small hit game flag is ON. As a result, when it is determined that the winning game is not being played (S601: NO), the special electric accessory game process is terminated as it is, and when it is determined that the winning game is being played (S601: YES), It is determined whether or not the winning opening 33a is open (S602). As a result, when it is determined that the special winning opening 33a is being opened (S602: YES), it is determined whether or not the opening time of the special winning opening 33a has elapsed (S603), and the special winning opening 33a is determined. If it is determined that the opening time has not elapsed (S603: NO), it is determined whether or not the maximum number of game balls has been won in the big winning opening 33a (S604).

  As a result, when it is determined that the game ball with the maximum number of winnings has not been won in the big winning opening 33a (S604: NO), the special electric equipment game process is ended as it is, and the largest winning opening 33a is won. When it is determined that a number of game balls have been won (S604: YES) or when it is determined that the opening time of the big prize opening 33a has passed (S603: YES), the big prize opening 33a is opened. Close (S605).

  If it is determined in S602 that the special winning opening 33a is not open (S602: NO), it is determined whether or not a winning game end condition is satisfied (S606). The winning condition is that 15 rounds have been completed for the first big hit game, two rounds have been finished for the second big hit game, and large for the small hit game. This is that the winning opening 33a is opened and closed twice.

  As a result, when it is determined that the winning game end condition is not satisfied (S606: NO), it is determined whether or not the closing time (interval time) of the special winning opening 33a has elapsed (S607). . As a result, when it is determined that the closing time of the special winning opening 33a has not elapsed (S607: NO), the special electric accessory game process is terminated as it is, and the closing time of the special winning opening 33a has elapsed. If it is determined that there is a game (S607: YES), the special winning opening 33a is opened (S608).

  When it is determined in S606 that the winning game end condition is satisfied (S606: YES), a winning game end process is performed (S609). Here, the winning game end processing will be described based on the flowchart of FIG.

  First, the winning game flag (big hit game flag or small hit game flag) is turned OFF (S609a). Then, it is determined whether or not the winning symbol is a small winning symbol (S609b). As a result, when the winning symbol is not the small winning symbol (S609b: NO), it is determined whether or not the winning symbol is a probability variation big winning symbol or a specific big winning symbol (S609c).

  As a result, when the winning symbol is a probability variation big winning symbol or a specific big winning symbol (S609c: YES), the probability varying flag is set to ON (S609d). Then, it is determined whether or not the winning symbol is a specific jackpot symbol (S609e). As a result, if the winning symbol is not a specific big winning symbol, that is, if it is a probabilistic big winning symbol (S609e: NO), the fluctuation shortening flag is set to ON (S609f), and the release extension flag is set to ON (S609g). . As a result, the variable time shortening function and the open time extending function are activated.

  On the other hand, when the winning symbol is a specific big winning symbol (S609e: YES), the special variation flag is set to ON (S609h). Next, the special variation counter is set to a predetermined value (S609i). The special variation counter is for counting a period during which the special variation pattern table is selected (in this embodiment, the number of times of variation of the special symbol is 30), and is set in S609i described later. For this reason, the special variation flag is turned OFF when the number of variations of the special symbol reaches 30 after the end of the second big hit game or after the end of the small hit game.

  Next, whether or not the release extension flag was turned on when the hit game flag was turned on, that is, whether or not the release time extension function was activated at the start of the hit game (big hit game or small hit game) that ended this time It is determined whether or not (S609j). As a result, when the release extension flag is ON when the winning game flag is ON (S609j: YES), the fluctuation shortening flag is set ON (S609f), and the release extension flag is set ON. (S609g). On the other hand, if the release extension flag is not ON when the winning game flag is turned ON (S609j: NO), the winning game end process is ended as it is. Thus, after the second big hit game due to the specific big hit symbol is completed, the operating state of the variable time shortening function and the open time extending function at the start of the second big hit game is maintained.

  Next, in the determination process of S609b, when it is determined that the winning symbol is a small winning symbol (S609b: YES), the same as when the above-mentioned winning symbol is a specific big winning symbol (S609e: YES) Process. That is, the special variation flag is set to ON (S609h), the special variation counter is set (S609i), and it is determined whether or not the release extension flag is ON when the hit game flag is ON (S609j). . In the present embodiment, the special variation counter is set to the number of variations of the special symbol 30 times. If the determination in S609j is affirmative, the fluctuation shortening flag is set to ON (S609f), the release extension flag is set to ON (S609g), and the operating state of the fluctuation time reduction function and the release time extension function is set. To maintain. On the other hand, if the determination in S609j is negative, the winning game end process is terminated.

  Next, in the determination process of S609c, when it is determined that the winning symbol is not the probability variation big hit symbol or the specific big hit symbol, that is, the normal big hit symbol (S609c: NO), the fluctuation shortening flag is set to ON (S609k). The release extension flag is set ON (S609l). Thereby, the operation of the variation time shortening function and the opening time extension function is started. Then, the fluctuation shortening counter is set to a predetermined value (S609m). The fluctuation shortening counter is for counting the operating period of the fluctuation time shortening function and the opening time extending function, and is set to the number of fluctuations of the special symbol 100 times in this embodiment. Thereby, the special electric accessory game process is completed.

  According to the configuration of the present embodiment described above, after the operation of the big winning device (special electric accessory) 33 based on the small hit game or the second big hit game (2R big hit game) is finished (the opening / closing operation of the big winning port 33a is ended). After), by using a special variation pattern table that does not depend on the game state, it is possible to share the variation pattern (special variation pattern) of the special symbol after the end of the second big hit game (2R big hit game) and after the end of the small hit game . Thereby, it is difficult for the player to distinguish between the gaming state after the second big hit game (2R big hit game) (latency probability changing state) and the gaming state after the small hit game ends based on the variation pattern of the special symbol. It becomes. For this reason, it becomes difficult for the player to estimate the latent probability change that is the gaming state after the end of the second big hit game (2R big hit game), and the latent probability change can be executed effectively. That is, since it is difficult to estimate the latent probability change without receiving a notification as to whether or not the gaming state is a latent probability change, the merit of receiving the notification increases.

  In addition, since the probability of occurrence of a big hit is low after the end of the small hit game, if the variation of the special symbol by the special variation pattern is continued, the reliability of the special variation pattern is lowered. For this reason, the special variation pattern table is selected after the end of the operation of the special winning device 33 until the predetermined period (in this embodiment, the number of times of variation of the special symbol is 30), and thereafter, the variation pattern table corresponding to the gaming state is selected. By switching, the game can be sharpened, and it can be suppressed that the reliability with respect to the special variation pattern is lowered.

  Next, based on FIGS. 13-19, the alerting | reporting process performed in the lottery probability alerting | reporting part 25b is demonstrated. First, the notification process S800 will be described based on the flowchart of FIG. First, as a result of the big hit lottery or the small hit lottery, it is determined whether or not the winning symbol is a specific big hit symbol or a small hit symbol (S801), and if it is determined that it is a specific big hit symbol or a small hit symbol (S801: YES), a firing instruction is issued (S802), and it is determined whether or not a firing of a predetermined time or more has been recognized after the firing instruction (S803). On the other hand, when it is determined that the symbol is not the specific big hit symbol or the small hit symbol (S801: NO), the notification process (S800) is terminated. If it is determined in S803 that the firing for a predetermined time or more has been recognized (S803: YES), a notification content determination process (S804) described later is executed to determine the notification content, and the determined notification content is notified of the lottery probability. This is displayed on the part 25b. On the other hand, when it determines with not having recognized the discharge more than predetermined time by said S803 (S803: NO), an alerting | reporting process (S800) is complete | finished.

  The firing instruction (S802) is made by the firing instruction means of the present invention mainly composed of the CPU 200a of the main control board 200, and is displayed on the firing instruction display unit 25c. Specifically, at a predetermined timing after the start of the variation display of the identification symbol, the firing instruction display unit 25c reads “Launch 30 seconds or more! ! ], “Launch more than 30 seconds before the symbol change display ends! ! "Launch 30 or more during reach", "Launch within 60 seconds (within the time limit) for 30 seconds or more (predetermined time)!" ! ”And the like are executed. In this embodiment, the firing instruction time is set to 30 seconds or more, but may be set to any number of seconds, or a plurality of firing instruction times may be set (a predetermined time or more). The longer the firing instruction time is set, the higher the effect of improving the operating rate of the gaming machine if the player follows the instruction.

  Whether or not the firing for a predetermined time or more has been recognized (S803) depends on whether or not the firing signal recognition means provided on the sub-control board 260 measures the firing time and the measurement time reaches a predetermined time set in advance. To be judged. The firing signal recognition means may measure the firing time based only on the signal from the touch switch 8a, or when the signal from the touch switch 8a is input and the signal from the firing stop switch 8b is not input. The firing time may be measured (ie, the firing handle is not touched when the firing handle is in contact with the firing handle). Alternatively, the firing time may be measured by determining whether or not the operation amount (rotation amount) of the firing handle 8 is greater than or equal to a predetermined amount. Alternatively, a ball detection sensor (not shown) may be provided in the passage path of the shot ball and connected to the shot signal recognition means, and a signal from the ball detection sensor may be input. When this ball detection sensor is provided, “shoot at least 18 shots (more than the specified number of balls) within 60 seconds (within the time limit)! ! May be notified when the number of shot balls is measured and a game ball of a predetermined number or more is detected within the time limit. The firing time is displayed on the firing time display unit 25d and displayed according to the firing time measurement of the firing signal recognition means (for example, “20 seconds remaining” is displayed). In this embodiment, the condition for notification is whether or not there is a fire for a predetermined time or longer. ! ”And whether or not there is a fire may be used as a notification condition (regardless of the fire time).

  Next, the notification content determination process (S804) will be described based on the flowchart of FIG. First, it is determined whether or not the latent probability has changed (S804a). If it is determined that the latent probability has changed (S804a: YES), the notification content is determined using the high-probability notification table (FIG. 15A). . On the other hand, when it is determined that the latent probability is not changed (S804a: NO), the notification content is determined using the low probability notification table (FIG. 15B). Whether or not it is a latent probability change is determined by whether or not it is a hit with a specific big hit symbol or whether it is a hit with a small hit symbol in the high probability gaming state (whether or not the probability change flag is ON).

  Next, the high-probability notification table and the low-probability notification table will be described with reference to FIG. When it is determined that the latent probability change, it is a case where the winning is a specific jackpot symbol and the lottery probability of the jackpot lottery is in a high probability state with a high probability. In the high probability state, it is more likely that the notification that the probability of being in the high probability state is high is displayed on the lottery probability notification unit 25b, compared to the low probability state in which the lottery probability of the big hit lottery is low. Is set to Specifically, when random numbers 0 to 9 are acquired from random numbers 0 to 99, there is a possibility that a high probability state exists based on the high probability notification table (FIG. 15A). The notification content indicating “20%” is determined, and the determination content is displayed on the lottery probability notification unit 25b. When random numbers of 10 to 29 are acquired, the notification content indicating that the possibility of a high probability state is “40%” is determined, and the determination content is displayed. When random numbers of 30 to 59 are acquired, the notification content indicating that the possibility of a high probability state is “60%” is determined, and the determination content is displayed. When random numbers of 60 to 89 are acquired, the notification content indicating that the possibility of a high probability state is “80%” is determined, and the determination content is displayed. When a random number of 90 to 99 is acquired, the notification content indicating that the possibility of a high probability state is “100%” is determined, and the determination content is displayed. In the case of the latent probability change, there is no indication that the possibility of the high probability state is “0%”.

  If it is determined that there is no latent probability change, it is a case where a small hit symbol is won in the low probability state, and it remains unchanged in the low probability state (probability change flag OFF state). In the low probability state, it is set so that there is a high possibility that a notification that “the possibility of being in a high probability state is low” is displayed on the lottery probability notification unit 25b compared to the high probability state. Specifically, when random numbers 0 to 9 are acquired from random numbers 0 to 99, there is a possibility that a high probability state exists based on the low probability notification table (FIG. 15B). The notification content indicating “0%” is determined, and the determination content is displayed on the lottery probability notification unit 25b. When random numbers of 10 to 49 are acquired, the notification content indicating that the possibility of a high probability state is “20%” is determined, and the determination content is displayed. When random numbers of 50 to 84 are acquired, the notification content indicating that the possibility of a high probability state is “40%” is determined, and the determination content is displayed. When the random numbers of 85 to 94 are acquired, the notification content indicating that the possibility of a high probability state is “60%” is determined, and the determination content is displayed. When random numbers of 95 to 99 are acquired, the notification content indicating that the possibility of a high probability state is “80%” is determined, and the determination content is displayed. If the latent probability is not changed, there is no indication that the possibility of the high probability state is “100%”.

  Once 100% is reported in the high probability state or 0% in the low probability state, the notification content will be changed as long as the gaming state does not change (or as long as it is not hit by the specific big hit symbol or small hit symbol again). It is good also as not performing a determination process, and it is good also as performing the same alerting | reporting in the subsequent alerting | reporting content determination processing (When alerting | reporting that it is 100%, alerting | reporting of a high-probability state determination is carried out after that). Moreover, although the aspect which displays predetermined reliability (probability which is a latent probability change) was shown on the lottery probability alerting | reporting part 25b as an aspect which alert | reports whether it is a latent probability change, the other aspect can also be employ | adopted. For example, the whole or part of the background display area may be used as a lottery probability notification unit, and notification may be made based on a difference in background color of an identification symbol, a difference in appearing characters, or a difference in mode. You may alert | report by the audio | voice and music output from the speaker installed in the gaming machine.

  The “notification with a predetermined reliability” refers to a notification mode that indicates to the player whether the gaming state has a high probability or a low probability. For example, in the case of notifying numerically, 100%, 50%, 30%, 0%, etc. are displayed. If the display is 100%, the fact that the lottery probability is high is notified, and 30% is displayed. If there is a possibility that the lottery probability is high, the probability that the lottery is low is higher. If the display is 0%, the fact that the lottery probability is low is notified. . Also, when notifying by changing the color of the background, character, etc., the whole or part of the background display area is changed to rainbow, red, blue, etc. If the color is rainbow, the lottery probability is high. It is also possible to notify that the possibility is high and notify the possibility that the probability is high in the order of red and blue. In addition, it is possible to notify whether or not the lottery probability is high by providing a plurality of modes having different characters (effects) and names and shifting between the plurality of modes (the mode of the transition destination). If the mode is a specific mode, the probability is high, and if the order of transition between modes is the specific order, the probability is high. Moreover, even if the notification execution lottery means is provided and the instructed condition is satisfied, the notification means may notify only when the random number lottery executed by the notification execution lottery means is won. Further, the reliability of notification may be changed according to the input time recognized by the contact state recognition means, such as the game state being notified more accurately as the firing time recognized by the firing signal recognition means is longer.

  Next, the contents of the firing instruction (S802) will be described based on FIGS. 16 (a) and 16 (b). FIG. 16 (a) shows that after starting the fluctuation, “Launch 60 seconds or more during reach! ! It is a timing chart when a firing instruction is given. In this example, among the 3-digit identification symbols, 2 digits are stopped and displayed with the same identification symbol, and the remaining one-digit symbol is changing. Reach fluctuation display (3 ・ ↓ ・ 3: ↓ is middle symbol variation It is instructed to fire for a predetermined time (60 seconds or more) within the time limit (within 300 seconds until the identification symbol stops displaying with a specific jackpot symbol) from the timing when it is . Launching for a predetermined time or longer may be firing continuously for 60 seconds, or may satisfy the condition if the accumulated time reaches 60 seconds. The time limit may or may not be notified. When the time limit is notified, the player can freely determine when to start the launch operation while watching the reach variation display. For example, it is possible to start firing only when it is determined that there is a high probability of winning after seeing the progress of reach fluctuation display to some extent (for example, starting firing after about 200 seconds have passed). If the time limit is not notified, the player cannot recognize how long the time limit is, and in order to obtain the notification reliably, the player is forced to fire immediately after the launch instruction, preventing stoppage. The effect is high, and the operating rate of the gaming machine can be improved. Then, when the firing is performed for 60 seconds or more (the firing signal recognition unit recognizes the firing for 60 seconds or more), the notification is made thereafter. The notification timing may be when the next fluctuation starts (immediately or immediately after), during a big hit fanfare display after a stoppage with a specific big hit symbol, or when the big winning opening 33a performs an opening / closing operation. It's okay when you are.

  FIG. 16 (b) shows that after launching the fluctuation, “Launch 60 seconds or more within 65 seconds! ! It is a timing chart when a firing instruction is given. This example is characterized in that the time limit (65 seconds) is set in a period from a predetermined timing after the start of variable display until the end of the specific big hit game. In addition, after the stoppage at the specific jackpot symbol, the period until the specific jackpot game starts, the so-called jackpot fanfare period, and the opening time is short (opening for a moment), so the specific jackpot game set in the opening / closing pattern is difficult to enter. It is characterized in that the instruction cannot be achieved (notification cannot be obtained) unless it is fired in any period of the execution period. The jackpot fanfare period and the specific jackpot game execution period are periods in which the shot ball is highly likely to be a useless ball and the player is likely to stop. By incorporating this period as a predetermined time, it is possible to effectively prevent stoppage and improve the operating rate of the gaming machine. In FIG. 16B, the instruction cannot be achieved unless it is fired in three periods of the identification symbol variation display time, the jackpot fanfare period, and the specific jackpot game execution period. As another aspect, it may be set so that the instruction can be achieved by firing in two periods. For example, in FIG. 16B, if the time limit is 55 seconds until the start of the specific jackpot game, and the predetermined time is 50 seconds, the instruction can be achieved if it is fired during the variation display time of the identification symbol and the jackpot fanfare period. Can do. Further, in FIG. 16B, if the time limit is 65 seconds until the end of the specific jackpot game and the predetermined time is 45 seconds, two periods of the identification symbol variation display time and the jackpot fanfare period, or the identification An instruction can be achieved if fired during two periods of the symbol variation display time and the specific jackpot game execution period. Of course, in this case as well, the firing instruction may be achieved by using three periods of the identification symbol variation display time, the jackpot fanfare period, and the specific jackpot game execution period. The instruction cannot be achieved unless it is fired in at least two periods.

  Next, a modification of the notification process will be described based on the flowchart of FIG. Only differences from the notification process of FIG. 13 will be described. In the notification process of FIG. 17, it is determined whether or not the winning is a specific big hit symbol or a small hit symbol (S801), and when it is determined that the specific big hit symbol or the small hit symbol is not hit (S801: NO) ) And a process (S806) for determining whether or not to execute the firing instruction. Here, the determination of whether or not to execute the firing instruction (S806) is made by random lottery or the like. If it is determined that the firing instruction is to be executed (S806: YES), the firing instruction shown in FIG. (S808). That is, notification is not performed. The present modification is characterized in that a firing instruction is given even if the lottery is not selected. When the player achieves the firing instruction, a notification must be made, so the firing instruction performed at this time has instruction contents that cannot be achieved. When it determines with not performing a discharge instruction | indication (S806: NO), an alerting | reporting process is complete | finished. By giving a launch instruction that cannot be achieved (S807), even if the lottery result is out of place (out of reach), the stoppage is prevented and the operating rate of the gaming machine is improved more effectively. Can do. When a fire instruction is given, the player does not know whether the reach fluctuation display result is a hit or miss, so that the player can obtain a notification (whether or not the latent probability change) at the time of hit. Must follow the firing instructions in any case (even if the answer is unknown).

  Next, the firing instruction in S807 will be described based on the timing chart of FIG. At the predetermined timing after the start of the variation display of the identification symbol, “Launch 60 seconds or more before the symbol stops! ! The firing instruction is executed. After that, the off symbol is stopped and displayed in a shorter time (40 seconds) than the firing instruction time (60 seconds), a display indicating that the firing instruction could not be achieved, and a notification of whether or not it is in a high probability state. The next fluctuation display is started without doing. That is, it is characterized by not informing by giving an instruction that cannot be achieved.

  Next, the re-notification process (S900) will be described based on the flowchart of FIG. In addition to the notification process of FIG. 13 or FIG. 17, the maximum notification process can be executed. The difference between this re-notification process (S900) and the notification process (S800) of FIG. 13 is that in the notification process (S800), it is determined whether or not a specific big hit symbol or a small hit symbol is hit (S801) Moreover, the re-notification process (S900) is different in that a determination is made as to whether or not a firing instruction is to be executed (S901). Since the subsequent processing is the same, description thereof is omitted. Note that whether or not to execute the firing instruction (S806) is determined by random number lottery or the like.

  The re-notification process (S900) is executed at a timing other than the timing at which the notification process of FIG. 13 or 17 is executed. For example, when the lottery result is out, it is determined whether or not to issue a firing instruction at the start of the variation display of the identification symbol (S901), and when it is determined to execute the firing instruction (S901: YES), “Launch more than 30 seconds! ! And the like are executed (S902). By executing this re-notification process (S900), it does not follow the firing instruction made at the timing of the specific big hit or the small hit, does not achieve the firing instruction, and is not informed of the high probability state. Even in this case, the player can obtain another notification opportunity by the re-notification process. Further, the notification content in the notification processing is determined based on the notification table in FIGS. 15A and 15B depending on whether or not the latent probability change (notification content determination processing in FIG. 14), and the determined content is a lottery probability notification unit. 25b. Since the notification table is set to display a high probability that the latent probability variation is high if the latent probability variation is made, the player can use the lottery probability notification unit 25b with a certain degree of reliability. The display content can be recognized. However, the greater the number of times that the lottery probability notification unit is notified, the higher the reliability. Therefore, by providing the re-notification process (S900), the player can obtain many notification opportunities, and can obtain more accurate information. In addition, the number of times that the firing instruction is executed is increased, and the more the number of times that the firing instruction is followed, the greater the profit that the player can obtain. Therefore, the player is more likely to follow the firing instruction. By providing the re-notification process (S900) in addition to the notification process (S800) as described above, it is possible to effectively prevent the stoppage and improve the operating rate of the gaming machine. In the re-notification process, whether or not to issue a firing instruction may be determined based on a random number acquired at the start winning timing.

(Second embodiment)
Next, a second embodiment of the present invention will be described. Only the parts different from the first embodiment will be described below.

  The gaming machine 1 according to the present embodiment is configured as a gaming machine (an ST machine that cuts the number of times of probability variation) that completes a probability variation game in a relatively short time and performs a limited probability variation game in which resumption of the next big hit game is not secured. Has been. Specifically, the probability variation game that occurs with the end of the big hit game is a predetermined number of times (in this example, four times) when the next big hit game is started, or when the number of fluctuations of the special symbol is 4 to 10 times. Exit when it reaches.

  FIG. 11 is a flowchart showing the latter half of the special symbol game process of the present embodiment, and corresponds to FIG. 5B of the first embodiment. As shown in FIG. 11, after the small hit flag is set to ON in the processing of S528, it is determined whether or not the probability variation flag is ON (S534). As a result, when the probability variation flag is not ON (S534: NO), the process proceeds to S529.

  On the other hand, if the probability variation flag is ON (S534: YES), the probability variation counter is decremented by 1 (S535), and it is determined whether or not the probability variation counter is zero (S536). The probability variation counter is for counting the operation period of the probability variation function, and is set in the process of S609n described later. As a result, if the probability variation counter is not zero (S536: NO), the process proceeds to S529. If the probability variation counter is zero (S536: YES), the probability variation flag is set to OFF (S537). Thereby, the operation of the probability variation function ends. Since the processing after S529 is the same as that in the first embodiment (see FIG. 5B), description thereof will be omitted below.

  FIG. 12 is a flowchart showing the symbol processing at the end of the winning game of the present embodiment, and corresponds to FIG. 10 of the first embodiment. As shown in FIG. 12, after the probability variation flag is set to ON, a probability variation counter is set (S609n). In this embodiment, the probability variation counter is set to 4. In other words, after the probability variation game is started with the end of the big hit game, the probability variation game is ended when the number of changes in the special symbol reaches four without generating a big hit. Also, in this embodiment, in order not to select the special variation pattern table after the probability variation game is finished, in this embodiment, in S609i, the special variation counter is set to the same number as the probability variation counter (the number of variations of the special symbol is 4 times). doing.

  As described above, in the gaming machine 1 in which the probability change game is finished in a short time, the latent probability change is finished in a short time after the second big hit game (2R big hit game) is finished, so it is difficult to effectively use the latent probability change. However, according to the configuration in which the special symbol is changed according to the special variation pattern that does not depend on the gaming state after the second big hit game (2R big hit game) or the small hit game as in the present embodiment, The variation pattern of special symbols (including special variation) (special variation pattern) is a pattern with a long variation time, so that a certain probability variation game period can be secured. For example, in the special variation pattern, by setting the variation time of one time when the result of determining whether the special symbol is right or wrong is set to 20 seconds, it is possible to set the maximum duration of the probability variation game to 80 seconds. In this way, by using the special variation pattern table after the end of the second big hit game (2R big hit game) or the small hit game, the gaming machine 1 adopting the limited probability variable game can effectively execute the latent probability change. It becomes possible, and notification of whether or not the gaming state is a latent probability change is received with a predetermined reliability, so that the gaming property can be improved and the interest of the player can be enhanced.

(Other embodiments)
As mentioned above, although the Example of this invention was described, this invention is not limited to this, Unless it deviates from the range described in each claim, it is not limited to the description word of each claim, and those skilled in the art Improvements based on the knowledge that a person skilled in the art normally has can be added as appropriate to the extent that they can be easily replaced.

  For example, in the first embodiment described above, the special variation pattern table is preset with “an out-of-range variation pattern with a variation time of 30 seconds” and “a plurality of hit variation patterns with a variation time of 40 to 120 seconds”. In the above description, one type of deviation variation pattern corresponds to a “special variation pattern”. However, the variation pattern set in the special variation pattern table may not take into account the result of the determination. Specifically, the “variation” that can be selected regardless of “special symbol success / failure determination result” or “the number of holdings at the start of special symbol variation / game state (normal game, short-time game, probability variation game, latent probability variation game)” Only the “variation pattern with a time of 30 seconds” may be set as a special variation pattern in the special variation pattern table. Even in such a case, the same effects as those of the first embodiment described above can be obtained.

  Also in the second embodiment described above, a “variation pattern with a variation time of 30 seconds” that can be selected regardless of the “result of determination of special symbol success” or “the number of holdings / game state at the start of variation of the special symbol”. May be set as the “special variation pattern” in the “special variation pattern table”. Even in such a case, the same effects as those of the second embodiment described above can be obtained.
