As shown in FIG. 1, a slot machine 1, which is an example of a gaming machine according to an embodiment of the present invention, has a rectangular parallelepiped housing 10. This housing 10 has an opening (not shown) on the front side (i.e., the surface on the near side in the direction penetrating the paper surface of FIG. 1) and a plate-shaped front door 20 that can open and close this opening.

The front door 20 has a light-transmitting display window 21 located in the approximate center, and is attached to the housing 10 in a lockable manner. The display window 21 is positioned so that multiple symbols arranged on the surface of each of the rotating reels 41, 42, and 43 (described later) can be seen when the opening of the housing 10 is closed by the front door 20.

The housing 10 also has a liquid crystal display device 22, an illumination device 23, and a speaker 24. The liquid crystal display device 22, the illumination device 23, and the speaker 24 are each located above the display window 21 of the front door 20. Various effects during play are performed using the liquid crystal display device 22, the illumination device 23, and the speaker 24. For example, the liquid crystal display device 22 displays various effect images (effect videos) during play, as well as specific information. Furthermore, the illumination device 23 turns on or off in a specific pattern when specific conditions are met, and the speaker 24 outputs a specific sound when specific conditions are met.

The housing 10 also has a payout opening 25 from which medals are paid out, a lower tray 26 that stores the medals paid out from the payout opening 25, and an operation unit 30. The payout opening 25, the lower tray 26, and the operation unit 30 are each located below the display window 21 of the front door 20.

The operation unit 30 has a medal insertion slot 31 for inserting medals as an example of a gaming medium, a bet switch 32 for betting medals, a start switch 33 operably provided on the front door 20 and operable to rotate each of the reels 41, 42, 43, and stop switches 34, 35, 36 operably provided on the front door 20 and operable to stop each of the reels 41, 42, 43 during rotation. Each switch of the operation unit 30 outputs an operation signal based on the player's operation. In addition, a medal sensor (not shown) is provided on the medal insertion slot 31, which detects the insertion of a medal into the medal insertion slot 31 by the player and outputs a detection signal.

The operation unit 30 is also provided with an adjustment switch (not shown) and a stored medal display unit (not shown), which is an example of a display unit. This stored medal display unit is configured to be able to display, in addition to the number of stored medals, that the game zone, which will be described later, is an advantageous zone.

2, the slot machine 1 includes a control device 100 that controls the entire slot machine 1, a reel unit 40, a reel position detection sensor 44, and a hopper unit 50 that pays out medals. The control device 100, the reel unit 40, the reel position detection sensor 44, and the hopper unit 50 are arranged inside the housing 10, together with a power supply device (not shown) that turns the main power supply of the slot machine 1 on and off, a setting unit 45 that is operated by an administrator when changing the settings of the slot machine 1, and the like.

The reel unit 40 is disposed approximately in the center of the interior of the housing 10, and is composed of multiple reels (three reels 41, 42, 43 in this embodiment) and stepping motors 61, 62, 63 that drive the reels 41, 42, 43. Each reel 41, 42, 43 is approximately cylindrical, and on its surface, as shown in FIG. 3, multiple symbols are arranged at intervals along the circumferential direction of each reel 41, 42, 43, and a reference point (not shown) is provided. The reference point is disposed, for example, in the center of the zero symbol (Bell A) of the reels 41, 42, 43.

Now, with reference to Figures 1 to 9, we will explain an overview of the game played on slot machine 1.

As shown in FIG. 1, when playing with the slot machine 1, first medals are inserted into the medal insertion slot 31, or medals (i.e., credits) stored are used to bet by operating the bet switch 32. When a preset number of medals (e.g., 1 to 3 medals) have been bet, the active line is activated and the start switch 33 can be operated, i.e., the game can be started. At this time, medals inserted in excess of the preset number, which is set according to the game status, etc., are stored as credits.

As shown in FIG. 4, the pay line is a virtual line for determining winning combinations, and each of the symbols on the reels 41, 42, and 43 displayed in the display window 21 is connected by this pay line. In this slot machine 1, the pay line is, for example, a line 70 sloping downward to the right, and is activated when a predetermined number of medals (for example, three medals) are bet. As an example, the symbols displayed in the display window 21 of this slot machine 1 are three symbols for each reel.

When the start switch 33 is operated in a state where the game can be started, a lottery (hereinafter referred to as an internal lottery) is performed by an electronic computer in the slot machine 1, and each rotating reel 41, 42, 43 starts to rotate. In this state, when any of the stop switches 34, 35, 36 is operated, the rotating reel 41, 42, 43 corresponding to the operated stop switch 34, 35, 36 stops, and the result according to the winning combination is displayed in the display window 21. When all the rotating reels 41, 42, 43 stop, a predetermined number of medals are paid out according to the winning combination, and one game ends. In this embodiment, when all the rotating reels 41, 42, 43 stop, if a combination of symbols set for each winning combination by the internal lottery is arranged on the pay line 70, it is determined that the combination of symbols arranged on the pay line 70 has won a prize. Note that when the combination of symbols corresponding to the winning combination does not stop on the pay line 70 (so-called loss), it is also included in the prize.

The series of actions in which the bet switch 32, start switch 33, and stop switches 34, 35, and 36 are operated to obtain a game result is called a game. The unit of play is a game, and one game is called a unit game.

During play, one play area is set from among multiple play areas, and one play state is set from among multiple play states. An internal lottery is then performed based on the set play area and play state. The play states include a first play state, a second play state, and a third play state, as shown in Figures 5 to 7.

The first game state is a game state for determining the type of replay role (see FIG. 9) and the probability of winning among the roles that are awarded by internal lottery (hereinafter simply referred to as winning roles), and is composed of RT0 and RT1 as shown in FIG. 5 as an example.

RT0 is set when the second gaming state transitions from a special role implementation state to a special role non-carryover state, or when the gaming state is initialized (e.g., when the RAM is cleared) (i.e., the first gaming state transitions from RT1 to RT0). In addition, the first gaming state immediately after the slot machine 1 is installed in a store or the like is also set to RT0. In other words, the first gaming state is always set to RT0 except when a type 1 BB is being implemented.

RT1 is set when the second game state transitions from a special role non-carryover state to a special role implementation state (i.e., the first game state transitions from RT0 to RT1). In RT1, as shown in FIG. 9, there is no possibility of winning a replay role or a type BB. Also, in RT1, the section transition lottery described below and the AT lottery described below are not performed.

The second game state includes a special role non-carryover state in which the winning type BB won by internal lottery is not carried over, a special role carryover state in which the winning type BB won by internal lottery is carried over, and a special role implementation state for implementing the winning type BB.

The special role non-carryover state is set when the number of medals paid out since the transition to the special role implementation state exceeds a predetermined number (e.g., 180 or 2 medals), or when a predetermined condition is met, such as initializing the game state (e.g., when the RAM is cleared).

The special role carryover state is set when a Type 1 BB is won through an internal lottery and certain conditions described below are met. Type 1 BB is a role continuous operation device (so-called big bonus) related to a Type 1 special role, and is an example of a special role. If Type 1 BB is carried over, the Type 1 BB lottery will not be held. In addition, the flag of the carried over Type 1 BB is configured not to disappear even if the setting value is changed, but it may be configured to disappear.

The special role implementation state is set when a special role is won and a prize is awarded by an internal draw, and includes a type 1 BB implementation state (shown as BB general in FIG. 6), an RB carryover state (shown as inside JAC in FIG. 6), and an RB implementation state (shown in JAC in FIG. 6). BB general is set when a special role is won. BB general is an example of a non-internal role state, and is set when an example of a special role, RB (JAC1-4 in FIG. 9), is not won by an internal draw. Inside JAC is an example of an internal role state, and is set when an RB (i.e., JAC1-4 in FIG. 9) is won by an internal draw and the RB is not won when the second game state is a type 1 BB implementation state BB general. During JAC is an example of a role implementation state, and is set when a winning RB wins a prize. During JAC, you can move to BB General by playing 12 games from the time you move to JAC, or by winning eight times with any winning hand during JAC.

The third game state is a state for determining the effects that will be performed during play, and as an example, as shown in Figure 7, it is composed of a general game state and an AT.

The general game state is a state in which the instruction function does not occur, and is set, for example, after the setting value is changed, the RAM is cleared, and the AT is finished, until the AT lottery is won. The slot machine 1 has, as the general game state, a normal state and a high probability state in which the probability of winning the AT lottery is higher than in the normal state (in other words, the AT is more likely to be awarded than in the normal state). The high probability state is configured to, for example, temporarily generate an instruction function, but to occur less frequently than the AT. As an example, the AT lottery is performed according to the winning hand by the internal lottery when the first game state is RT0 and the game zone is an advantageous zone. The transition from the normal state to the high probability state is performed, for example, by winning the high probability state transition lottery, which is performed when the internal lottery is performed when the first game state is RT0 and the game zone is an advantageous zone, and the AT lottery is not won as a result of the internal lottery.

The AT is the state where the instruction function occurs, and is set to the number of plays that have elapsed since the third gaming state transitioned to the AT until the period during which play is possible in the AT is reached. In the AT, the push order for a push order role that will result in the payout of medals is announced, and the expected value of medals won is configured to be higher than in the general gaming state (e.g., the normal state).

The AT is an example of a special game state that is more advantageous to the player than the normal state, and the AT lottery is an example of a special game state lottery. Also, the AT extension lottery may be included in the special game state lottery.

The game zone is a state for determining whether or not processing related to the instruction function is performed, and as an example, it is composed of an advantageous zone and a normal zone, as shown in Figure 8.

The advantageous zone is a zone in which processing related to the instruction function and lottery can be executed, and is set until the game zone meets the conditions for ending the advantageous zone after winning the zone transition lottery, which is conducted based on the results of the internal lottery conducted in the normal zone. Note that advantageous zones include advantageous zones in which the third game state progresses in a general game state, and advantageous zones in which the third game state progresses in a special game state (i.e., AT).

The normal section is a section in which processing related to the instruction function and lottery drawing cannot be performed, and is set when no advantageous section is set as a gaming section. In the normal section, the third gaming state progresses in a general gaming state.

The instruction function is a function that instructs the player in some way on the operation procedure (e.g., the order of pressing for a pressing sequence role) or operation method that affects the ball output, such as a function that instructs the player on the order of pressing for a winning role by operating the stop switches 34, 35, 36 in a predetermined order of operation, and/or a function that instructs the operation position of a winning role when the positions of the rotating reels 41, 42, 43 when the stop switches 34, 35, 36 are operated are in predetermined operation positions. In other words, the AT is set as the third game state only when the game zone is a favorable zone.

Next, the control device 100 will be described. As shown in FIG. 2, the control device 100 is composed of a main control unit 110 and a sub-control unit 120.

The main control unit 110 and the sub-control unit 120 each include a CPU that performs calculations, a storage device (e.g., ROM and RAM) that stores programs or data necessary for the progress of the game, etc. The main control unit 110 includes an internal lottery unit 111, a reel control unit 112, a game result determination unit 113, a section control unit 114, a game status control unit 115, a measurement unit 116, and a setting value control unit 117, and performs control to progress the game. The sub-control unit 120 includes a performance control unit 121, and performs control to perform various performances, etc.

Note that each of the main control unit 110 and the sub-control unit 120 described below is a function realized, for example, by the CPU executing a specific program.

The internal lottery unit 111 has multiple internal lottery tables, and performs an internal lottery when the operation of the start switch 33 is accepted. In detail, the internal lottery unit 111 determines the first game state (in other words, the RT state) when the operation of the start switch 33 is accepted, and selects an internal lottery table based on the determined RT state. Then, the internal lottery unit 111 performs an internal lottery based on the selected internal lottery table and a random number obtained when the operation of the start switch 33 is accepted.

For example, the winning combination is determined based on the internal drawing table shown in FIG. 9. This internal drawing table is provided for each RT state, and has information about the winning area that may result in a win through the internal drawing. At least one combination of symbols is associated with this winning area.

In FIG. 9, for each of the RT state and the second game state, the winning areas that may result in a win are indicated by an "O", and the winning areas that may not result in a win are indicated by an "X". In other words, each internal lottery table has a number of areas (number-placement areas) in which roles corresponding to the random numbers obtained when the start switch 33 is operated are stored, and each of these areas corresponds to a winning area indicated by an "O" in FIG. 9.

The slot machine 1 has an operation mode role in which the number of medals paid out changes based on the operation mode as a role for winning an internal lottery. In this embodiment, the operation mode includes a first operation mode in which the stop switches 34, 35, and 36 are operated in a predetermined operation sequence, and a second operation mode in which the stop switches 34, 35, and 36 are operated in an operation sequence different from the first operation mode. The operation mode role is configured so that the number of medals paid out based on the second operation mode is less than the number of medals paid out based on the first operation mode.

As an example, the operation mode roles include a first role and a second role that wins at the same time as the first role and pays out fewer medals than the first role when it wins. The first role is won by operating the stop switches 34, 35, and 36 in the first operation mode, and the second role is won by operating the stop switches 34, 35, and 36 in a second operation mode that is different from the first operation mode.

9, the slot machine 1 has the push order roles of "left bell", "center, left, right bell", "center, right, left bell", "right, left, center bell" and "right, center, left bell" as examples of the first role, and the push order roles of "left 1 coin role", "center, left, right 1 coin role", "center, right, left 1 coin role", "right, left, center 1 coin role" and "right, center, left 1 coin role" as examples of the second role. When each push order "bell" is won, the push order "1 coin role" of the push order different from each push order "bell" is also won at the same time. In other words, when the stop switches 34, 35, 36 are operated according to the push order set for each push order "bell", in other words in the first operation mode, the "bell" from which 8 medals are paid out is won. On the other hand, if the stop switches 34, 35, and 36 are operated in a different order from the operation order set for each push order role, in other words, in the second operation mode, a "1 coin role" in which one medal is paid out is won.

For each push order role shown in FIG. 9, the set push order is written immediately before the "bell" or "1 coin role." For example, in the case of a "left bell," the "bell" is won by operating the left stop switch 34, the middle stop switch 35, and the right stop switch 36 in that order, or the left stop switch 34, the right stop switch 36, and the middle stop switch 35 in that order. Also, for example, in the case of a "middle-right-left 1 coin role," the "1 coin role" is won by operating the middle stop switch 35, the right stop switch 36, and the left stop switch 34 in that order.

The operation mode is not limited to the order in which the stop switches 34, 35, and 36 are pressed, but may be the operation timing of the stop switches 34, 35, and 36, or a combination of the order in which the stop switches 34, 35, and 36 are pressed and the operation timing.

The reel control unit 112 controls the stepping motors 61, 62, and 63 of the reel unit 40 in response to the operation of the start switch 33 or each stop switch 34, 35, and 36 to start or stop the rotation of each reel 41, 42, and 43 (i.e., controls the rotation of the reels 41, 42, and 43).

For example, when the start switch 33 is operated while all the reels 41, 42, 43 are stopped, the reel control unit 112 spins all the reels 41, 42, 43. When any of the reels 41, 42, 43 is spinning and the stop switch 34, 35, 36 corresponding to the spinning reel 41, 42, 43 is operated, the reel control unit 112 stops the reel 41, 42, 43 corresponding to the operated stop switch 34, 35, 36.

When stopping each of the reels 41, 42, 43, the reel control unit 112 performs pull-in control or kick-off control according to the winning combination obtained by the internal drawing and the timing at which each of the stop switches 34, 35, 36 was operated (i.e., the position of the corresponding reel 41, 42, 43 when the operation of each of the stop switches 34, 35, 36 was accepted). Pull-in control is control that stops the rotation of each of the reels 41, 42, 43 so that the symbols corresponding to the winning combination are pulled onto the pay line 70. Kick-off control is control that stops the rotation of the reels 41, 42, 43 so that the symbols corresponding to the non-winning combination do not line up on the pay line 70.

The game result determination unit 113 determines the game result based on the result of the internal lottery and the result of the stop control of the rotating reels 41, 42, and 43. The game result includes, for example, a determination of whether or not a winning combination has been awarded based on the symbols that line up on an active line.

The game result determination unit 113 controls the hopper unit 50 to pay out medals based on the determined game result or on the acceptance of the operation of the settlement switch. Medals paid out based on the game result (i.e., medals obtained by winning a winning combination or winning a prize) are first stored as credits. Then, if the result of storing medals exceeds the credit upper limit (e.g., 50 medals), the medals exceeding the upper limit are paid out from the hopper unit 50. Also, if there is one or more stored medals (i.e., if the credit is 1 or more) and the settlement switch is operated, the stored medals are paid out from the hopper unit 50.

For example, when the third gaming state transitions to the AT, the gaming result determination unit 113 outputs a signal indicating that the third gaming state has transitioned to the AT to the hall computer to notify the administrator.

The interval control unit 114 sets the play interval from among multiple play intervals (in this embodiment, a normal interval and an advantageous interval).

Specifically, when the playing area is a normal area, the area control unit 114 performs an area transition lottery to determine whether the playing area should remain a normal area or should be assigned an advantageous area, and sets the playing area to an advantageous area if the area transition lottery is won. The winning or losing of the area transition lottery is determined, for example, by whether or not the lottery that is held when a role that results in a area transition lottery (i.e., a role subject to the lottery) is won by an internal lottery.

The interval transition drawing may or may not have a difference in the winning probability depending on the setting value of the slot machine 1. When making a difference in the winning probability of the interval transition drawing, for example, this may be achieved by setting a set difference in the winning probability of the internal drawing of the lottery target role, or by setting a set difference in the winning probability of the drawing held when the lottery target role is won by the internal drawing.

The section control unit 114 is configured to be able to assign one game section in which an internal lottery is performed from among a plurality of game sections, including a normal section in which processing related to the instruction function and lottery cannot be performed and game play proceeds in a general game state, and an advantageous section in which processing related to the instruction function and lottery can be performed and game play proceeds in a general game state or a special game state.

In this embodiment, when the game zone is an advantageous zone, the zone control unit 114 determines whether to leave the game zone as an advantageous zone or to grant a normal zone. For example, the zone control unit 114 grants a normal zone when the game zone is an advantageous zone and a predetermined end condition is met. The end condition is met, for example, when the number of games that have elapsed since the game zone was set to an advantageous zone (i.e., the number of games consumed in the advantageous zone) measured by the measurement unit 116 reaches a predetermined value (e.g., 1500 games), or when the difference in the number of medals since the game zone was set to an advantageous zone reaches a predetermined value (e.g., 2400 medals). The difference in the number of medals (in other words, the difference in the number of medals paid out) refers to the cumulative difference between the number of medals bet and the number of medals paid out.

When the game zone transitions to a favorable zone, the zone control unit 114 displays that it is a favorable zone via a display unit provided in the operation unit 30 only if the instruction function is activated during the favorable zone and the average payout rate exceeds 100% when playing the game to pay out the maximum number of small winning coins, excluding the reels (i.e., RB or CT) and the reels continuous operation device (i.e., type 1 BB).

The game state control unit 115 controls the transition between the first game state, the second game state, and the third game state.

For example, the game state control unit 115 sets one RT state in which an internal lottery is performed from among multiple RT states (RT0 and RT1 in this embodiment). Specifically, as described above, the game state control unit 115 sets the first game state to RT0 when the second game state transitions to a special role non-carryover state, and sets the first game state to RT1 when the second game state transitions to a special role implementation state.

In addition, when a preset drawing condition (hereinafter simply referred to as the drawing condition) is satisfied, the game state control unit 115 performs a special game state drawing to determine whether or not to transition the game state to a special game state that is more advantageous to the player than the normal state. As described above, the special game state drawing includes an AT drawing, a high probability state transition drawing, and an extension drawing of the AT or high probability state. The drawing conditions are preset according to the special game state to be transitioned to. For example, an AT drawing is performed when a predetermined role (for example, a so-called rare role such as cherry or watermelon) is won by an internal drawing. Also, for example, a high probability state transition drawing is performed when a rare role is won by an internal drawing when the first game state is RT0 and the game zone is an advantageous zone, but an AT drawing is not won.

As shown in FIG. 2, the game status control unit 115 has a high probability game number awarding unit 1151 and a period extension unit 1152.

The high probability play number awarding unit 1151 is configured to award a high probability play number, which is the number of plays that can be played in a high probability state.

For example, the high-probability game number awarding unit 1151 awards a high-probability game number at any timing when the following conditions are satisfied. The high-probability game number awarded at one time is one game or more, and it can be configured so that the expectation of the high-probability game number awarded varies depending on a set value, for example.
- If the high probability state transition lottery is won when the third game state is the "normal state."
- If you win the high probability state extended lottery when the third game state is the "high probability state."
When the third gaming state is "AT" and an extended lottery in a highly probable state is won, "AT" may include a pseudo bonus. During the pseudo bonus, for example, a number of highly probable games is awarded according to the winning combination.
- If a specified role (for example, a so-called rare role) is won through an internal lottery, regardless of the game status.
When an operation mode role is won by an internal lottery and a game is played by the second operation mode. For example, when the game zone is an advantageous zone and the third game state is a general game state, the high probability game number awarding unit 1151 awards the high probability game number when the second role (for example, "1 piece role") is won by the second operation mode.

The period extension unit 1152 is configured to be able to extend the special play period, which is the period during which play can be performed in the special play state (in this embodiment, AT), in accordance with at least a portion of the awarded number of high-probability plays.

In this embodiment, the period extension unit 1152 is configured to be able to extend the special play period according to the number of unplayed high probability play periods among the number of high probability play periods granted. Specifically, the period extension unit 1152 extends the extended special play period by a larger amount as the number of high probability play periods increases.

The special game period that is extended when the number of highly probable games is greater than zero and less than the first threshold is the first special game period, and the special game period that is extended when the number of highly probable games is equal to or greater than the first threshold is the second special game period. In this case, the period extension unit 1152 gradually increases the extended special game period so that the first special game period is smaller than the second special game period. For example, if the second threshold is a value smaller than the first threshold, the period extension unit 1152 sets the first special game period to a length that allows the player to win medals equivalent to RB implementation (e.g., 60 medals) when the number of highly probable games is greater than zero and less than the second threshold, and sets the first special game period to a length that allows the player to win medals equivalent to BB implementation (e.g., 180 medals) when the number of highly probable games is equal to or greater than the second threshold and less than the first threshold. Also, for example, the period extension unit 1152 grants a number of parameters according to the number of high-probability games, and determines the length of the second special game period according to the number of granted parameters. The length of the second special game period is determined, for example, by a calculation using the number of granted parameters, or by drawing a lottery the number of times corresponding to the number of granted parameters, and is determined based on the result of the drawing.

For example, the period extension unit 1152 extends the special game period based on the end condition of the advantageous zone and the current game information. A specific example is shown below.
- If the conditions for ending the advantageous zone include the number of elapsed games since the advantageous zone was granted reaching a first number of games (e.g., 1,500 games), the period extension unit 1152 extends the special play period if the second number of games from the elapsed number of games to the first number of games (i.e., the number of games remaining until the end of the advantageous zone) is less than or equal to a first predetermined value (e.g., 300 games).
- If the conditions for ending the advantageous zone include the first payout difference in medals from the time the advantageous zone was granted to the present reaching a second payout difference (e.g., 2,400 medals), the period extension unit 1152 extends the special game period if the third payout difference from the first payout difference to the second payout difference (i.e., the remaining payout difference until the end of the advantageous zone) is less than a second predetermined value (e.g., 900 medals).

The measurement unit 116 measures, for example, the number of games played since the game zone was set to the advantageous zone (i.e., the number of games played in the advantageous zone) and the difference in the number of medals paid out since the game zone was set to the advantageous zone, based on the game result determined by the game result determination unit 113. Also, for example, the measurement unit 116 measures the time elapsed from a starting point set after all of the rotating reels 41, 42, 43 have started rotating steadily.

The setting value control unit 117, by having the administrator operate the setting unit 45, sets one setting value from among multiple setting values (six in this embodiment) with different degrees of advantage for the game (e.g., machine odds). The difference in the degree of advantage is realized, for example, by setting a difference in the probability of winning the internal lottery for a specified role. The setting value control unit 117 also sets the degree of advantage related to the ball output, such as the transition rate to the advantageous zone, the AT lottery, and the AT additional lottery.

An example of a method for setting the set value is shown below. This method is carried out in the order of (1) to (7).
(1) Open the front door 20.
(2) Turn off the main power supply of the slot machine 1. By turning off the main power supply of the slot machine 1, all of the rotating reels 41, 42, 43 that are rotating stop, but the stopping of the rotating reels 41, 42, 43 does not determine whether or not a prize has been won.
(3) The setting change key is inserted into a predetermined position in the setting section 45, and the setting change mode is changed from OFF to ON.
(4) Turn on the main power of the slot machine 1.
(5) The current setting value is displayed, for example, on the stored medal display section of the operation section 30. By operating a predetermined button, the setting value displayed on the stored medal display section is adjusted to a desired setting value.
(6) Operate the start switch 33. By operating the start switch 33, the setting value of the slot machine 1 is changed to the setting value displayed on the accumulated medal display unit.
(7) Change the setting change mode from on to off and remove the setting change key.

The performance control unit 121 has an alarm unit 1211, and determines the performance for each game based on the game state in which the internal lottery was performed and the result of the internal lottery, and outputs the determined performance via the liquid crystal display device 22, the illumination device 23, and the speaker 24.

The notification unit 1211 notifies information related to the number of high-probability games (an example of a first notification unit). For example, the information related to the number of high-probability games includes the number of unplayed high-probability games, the number of played high-probability games, and the combined number of played high-probability games and the number of unplayed high-probability games, and notifies at least one of these pieces of information. Information related to the special game period is notified, for example, using the liquid crystal display device 22, the illumination device 23, or the speaker 24.

The notification unit 1211 is also configured to be able to notify the extension of the special play period using an icon representing the number of highly probable plays when the special play period is extended (an example of a second notification unit). Notification of the extension of the special play period using an icon representing the number of highly probable plays is performed, for example, using the liquid crystal display device 22. One example of a presentation for notifying the extension of the special play period is a presentation in which multiple icons resembling medals are displayed, each of which has a letter representing the number of highly probable plays attached to it, and instead of the icons disappearing, the number of extended plays in the special play period is displayed.

Next, the process of extending the special game period of the slot machine 1 will be described with reference to FIG. 10. The process described below is performed, as an example, by the CPU executing a predetermined program.

As shown in FIG. 10, during the AT, when the second number of games from the number of elapsed games to the first number of games (e.g., 1,500 games) becomes 300 games or less, or the third payout difference from the first payout difference in medals from when the advantageous zone was granted to the present to the second payout difference (e.g., 2,400 medals) becomes 900 medals or less (step S1), the period extension unit 1152 determines whether the number of unconsumed high-probability games is equal to or greater than the first threshold value (step S2).

When it is determined that the number of unconsumed high probability games is equal to or greater than the first threshold, the period extension unit 1152 extends the special game period by a second special game period, which is a larger extension amount than the first special game period (step S3), and the special game period extension process ends.

When it is determined that the number of unconsumed high-probability games is smaller than the first threshold, the period extension unit 1152 extends the special game period by the first special game period, and the extension procedure of the special game period ends. In detail, the period extension unit 1152 determines whether the number of unconsumed high-probability games is equal to or greater than the second threshold and smaller than the first threshold (step S4). When it is determined that the number of unconsumed high-probability games is equal to or greater than the second threshold and smaller than the first threshold, the period extension unit 1152 extends the special game period by the amount equivalent to the implementation of BB, that is, the amount of balls equivalent to the balls obtained when BB is implemented (180 balls) (step S5). Also, when it is determined that the number of unconsumed high-probability games is smaller than the second threshold, the period extension unit 1152 extends the special game period by the amount equivalent to the implementation of RB, that is, the amount of balls equivalent to the balls obtained when RB is implemented (for example, 60 balls) (step S6).

Slot machine 1 can achieve the following effects:

The slot machine 1 is equipped with a high probability play number granting unit 1151 configured to be able to grant a high probability play number, which is the number of plays that can be played in a high probability state, and a period extension unit 1152 configured to be able to extend a special play period, which is the period during which play can be performed in an AT (an example of a special play state), according to at least a portion of the granted high probability play number. With this configuration, for example, it is possible to extend the special play period by using at least a portion of the high probability play number accumulated by the player himself during the course of play. As a result, it is possible to realize a slot machine 1 that can provide new gameplay.

The slot machine 1 can optionally employ any one or more of the following configurations. In other words, any one or more of the following configurations can be optionally deleted if they were included in the above embodiment, and can be optionally added if they were not included in the above embodiment. By employing such a configuration, it is possible to realize a slot machine 1 that can more reliably prevent a decrease in a player's motivation to play due to the end of the advantageous zone.

The period extension unit 1152 is configured to be able to extend the special play period according to the number of high probability play times that have not been played out of the number of high probability play times that have been granted. This allows the number of high probability play times that have not been played out to be used effectively in play. Therefore, it becomes difficult for the player to recognize that the number of high probability play times that have accumulated but not been used up in the course of play up to now has been accumulated in vain. In addition, because the special play period is extended according to the number of high probability play times that have not been used out, the number of high probability play times that have not been used out is returned to the player as winning balls. Therefore, the player can feel that the number of high probability play times that have not been used out to be used more effectively.

The period extension unit 1152 extends the special play period based on the end conditions of the advantageous zone and the current play information.

The conditions for ending the advantageous zone include the number of plays that have elapsed since the advantageous zone was granted reaching a first number of plays, and the period extension unit 1152 extends the special play period when a second number of plays from the elapsed number of plays to reaching the first number of plays is equal to or less than a first predetermined value. As a result, when the remaining number of plays that can be played in the advantageous zone is somewhat limited, the special play period is extended according to the number of high-probability plays. As the number of high-probability plays is effectively utilized as the end of the advantageous zone approaches, it is possible to more reliably prevent a decrease in the player's motivation to play due to the end of the advantageous zone.

The conditions for ending the advantageous zone include a first payout difference in medals from when the advantageous zone was granted to the present reaching a second payout difference, and the period extension unit 1152 extends the special play period when a third payout difference from the first payout difference to the second payout difference is equal to or less than a second predetermined value. As a result, when the payout difference in medals obtained in the advantageous zone is somewhat limited, the special play period is extended according to the number of high probability plays. As the number of high probability plays is effectively utilized as the end of the advantageous zone approaches, it is possible to more reliably prevent a decrease in the player's motivation to play due to the end of the advantageous zone.

The period extension unit 1152 extends the special play period longer as the number of high probability plays increases. As a result, the more high probability plays that are accumulated, the more they are returned to the player as balls, so the player can play while looking forward to the extension of the special play period based on the number of high probability plays.

If the special play period that is extended when the number of high-probability plays is greater than zero and less than the first threshold is defined as the first special play period, and the special play period that is extended when the number of high-probability plays is equal to or greater than the first threshold is defined as the second special play period, the period extension unit 1152 increases the extended special play period so that the first special play period is smaller than the second special play period. In this way, since the extension period of the special play period differs depending on the number of high-probability plays, the player can enjoy the added fun of guessing how much the special play period will be extended depending on the number of high-probability plays, in addition to progressing with the game.

The period extension unit 1152 assigns a number of parameters according to the number of high-probability plays, and determines the length of the second special play period according to the number of parameters. Because the length of the second special play period is determined via a number of parameters according to the number of high-probability plays, it is more difficult to know how long the second special play period will be than when the length of the second special play period is determined uniquely by the number of high-probability plays without using parameters. Therefore, when playing a special game corresponding to the second special play period, the player can feel the excitement of not knowing how long this special game will last. This provides more variety in gameplay.

The high-probability play number awarding unit 1151 is configured to be able to award high-probability play numbers not only when the game state is a general game state, but also when the game state is an AT. In this way, there are various opportunities for the awarding of high-probability play numbers, and this in turn gives hope for the possibility of extending the special game period.

The device is equipped with a notification unit 1211 that notifies information regarding the number of highly probable plays. This allows the player to know the number of highly probable plays and play while looking forward to an extension of the special play period.

The device is equipped with a notification unit 1211 that is configured to notify the player of the extension of the special play period using an icon representing the number of highly probable plays when the special play period is extended. This notification allows the player to realize that the number of highly probable plays accumulated in previous games is being used to extend the special play period.

The roles that can be won by the internal lottery include operation mode roles in which the number of medals paid out varies based on the operation mode, and the operation modes include a first operation mode and a second operation mode. The operation mode roles are configured so that the number of medals paid out based on the second operation mode is less than the number of medals paid out based on the first operation mode. When an operation mode role is won, the high probability play number awarding unit 1151 awards a high probability state based on play in the second operation mode. With this configuration, when a player wins an operation mode role, the player plays while being aware of whether the game will end with a simple medal payout or whether there is a possibility that a high probability state will be awarded. As a result, a slot machine 1 that can provide new gameplay properties can be realized.

The slot machine 1 can also be configured as follows:

The slot machine 1 is not limited to the above embodiment, and may adopt any configuration including the highly-probable play number awarding unit 1151 and the period extension unit 1152. For example, the interval control unit 114 and the notification unit 1211 may be omitted. In the above embodiment, the notification unit 1211 serving as the first notification unit and the second notification unit is provided, but a first notification unit and a second notification unit that are independent of each other may be provided. In the above embodiment, the combination that is won by the internal lottery includes an operation mode combination, but the combination that is won by the internal lottery does not have to include an operation mode combination.

The period extension unit 1152 may be configured to be able to extend the special play period in accordance with at least a portion of the number of high-probability plays that have been awarded. For example, the period extension unit 1152 may be configured to be able to extend the special play period in accordance with some or all of the number of high-probability plays that have not yet been played out of the number of high-probability plays that have been awarded, or may be configured to be able to extend the special play period in accordance with some or all of the number of high-probability plays that have already been played out, or may be configured to be able to extend the special play period in accordance with some or all of the number of high-probability plays that have been awarded, whether played out or not.

The period extension unit 1152 may be configured to extend the special play period based on other factors, not just on the end conditions of the advantageous zone and the current play state.

The first special play period is not limited to the case where, when the number of high-probability plays is greater than zero and less than the second threshold, a length capable of winning medals equivalent to playing an RB is set, and, when the number of high-probability plays is equal to or greater than the second threshold and less than the first threshold, a length capable of winning medals equivalent to playing a type BB is set. For example, the first special play period may be set to the same length without setting a threshold, or multiple thresholds may be set to three or more different lengths depending on the number of high-probability plays.

The slot machine 1 is not limited to having a highly probable play number awarding unit 1151 and a period extension unit 1152, and can also be configured as shown in Figures 11 to 14. Each slot machine 1 in Figures 11 to 14 can also extend the special play period by using at least a portion of the highly probable play number accumulated by the player himself during the game, for example, and can provide new gameplay.

The slot machine 1 of FIG. 11 has an acquisition increase unit 1153 instead of the period extension unit 1152. The acquisition increase unit 1153 is configured to increase the medals that can be acquired in the special game period according to at least a part of the number of high-probability games awarded. The slot machine 1 of FIG. 12 has a game medium conversion unit 1154 instead of the period extension unit 1152. The game medium conversion unit 1154 is configured to convert at least a part of the number of high-probability games awarded into medals that can be acquired in the special game period. The slot machine 1 of FIG. 13 has a period determination unit 1155 instead of the period extension unit 1152. In the slot machine 1 of FIG. 13, the special game period includes a first period and a second period that starts after the end of the first period. The period determination unit 1155 determines the length of the second period according to at least a part of the number of high-probability games awarded. The slot machine 1 of FIG. 14 includes a parameter determination unit 1156 and a parameter conversion unit 1157 instead of the high probability play number granting unit 1151 and the period extension unit 1152. The parameter determination unit 1156 determines a first parameter related to the special play state and a second parameter related to the expected degree of acquisition of game media (medals), which is a parameter different from the first parameter. The parameter conversion unit 1157 is configured to be able to convert the second parameter into the first parameter. The first parameter corresponds to the length of the special play state and the number of coins acquired in the special play state, and the second parameter corresponds to the length of the high probability state and the expected degree of winning in the special play state. For example, when the second parameter is the length of the high probability state, the parameter conversion unit 1157 is configured to be able to convert the unused second parameter (i.e., the number of unconsumed high probability plays) into the first parameter.

The special game state may be more advantageous to the player than the general game state, and may have specifications that allow the period during which play can be extended in the special game state. For example, the special game state is not limited to AT, but may also be ART. The high probability state may also be included in the special game state. In this case, a lottery for transitioning to the high probability state may be an example of a special game state lottery. A lottery for extending the high probability state may also be included in the special game state lottery. In addition, the special game state may be a set management type in which a predetermined number of games is one set, or a game number management type.

When the special play period is extended, the extended AT may start immediately after the end of the AT before the extension, or the game may transition to the normal play state once after the end of the AT before the extension, and then transition to the AT again to start the extended AT.

When the advantageous zone ends by satisfying the ending condition, for example, an ending performance may be executed just before it ends. While the ending performance is being executed, the AT play period will not be extended even if the extension condition is satisfied. Therefore, for example, if the ending performance is executed when 1,450 games are reached after the transition to the advantageous zone, the period extension unit 1152 can consider the first play count to be 1,450 games, not 1,500 games.

The conditions for ending the advantageous zone may include the case where the number of continuous plays in the advantageous zone reaches 1500 games or the payout difference reaches 2400 coins, and the period extension unit 1152 grants (sets) an extension of the special play period according to the number of highly probable plays. When an extension of the special play period is granted according to the number of highly probable plays, the zone control unit 114 performs a reset process to end the advantageous zone once and set it to an advantageous zone again. Even if this reset process is performed, it is preferable that the information that an extension of the special play period has been granted (set) is maintained. As a result, in the advantageous zone after the reset process, a special game is played for the extended amount of the special play period granted (set) before the reset process. This reduces the restriction on balls due to the advantageous zone being finite (i.e., the phenomenon in which not many balls are obtained due to the existence of an advantageous zone).

In step S2 of FIG. 10, it is determined whether the number of unconsumed high-probability plays is equal to or greater than a first threshold value, but instead it may be determined whether or not a number of high-probability plays exists (whether the number of unconsumed high-probability plays is greater than zero).

The conditions for the end of the advantageous zone (for example, the "number of Gs remaining in the advantageous zone" and the "remaining difference in number of coins until the end of the advantageous zone") may be displayed on the liquid crystal display device 22. Since the remaining playable period in the advantageous zone is displayed, the player can have hope for an extension of the special play period.

The conditions for the zone control unit 114 to forcibly set the advantageous zone to the normal zone are not limited to the number of games in the advantageous zone reaching 1500 games and the number of medal payout differences in the advantageous zone reaching 2400. The advantageous zone may be forcibly set to the normal zone under conditions other than these conditions, or the conditions for forcibly setting the advantageous zone to the normal zone may not be set. For example, the advantageous zone may be forcibly set to the normal zone when the number of games in the advantageous zone reaching 1500 games, but the advantageous zone may not be forcibly set to the normal zone when the number of medal payout differences in the advantageous zone reaching 2400. Also, for example, except when the advantageous zone is forcibly set to the normal zone, once the game zone is set to the advantageous zone, the advantageous zone may not be set to the normal zone until a so-called bonus (e.g., a type BB) is won once or the push order role (e.g., a push order bell) that maximizes the payout of medals is notified once.

When the setting value of the slot machine 1 is changed, the play area may be set to take over the state immediately before the setting value of the slot machine 1 was changed, or may be set to a pre-defined initial state (i.e., initialized).

In the above embodiment, the display unit is configured to display that the game is in a favorable zone only when the instruction function is activated during the favorable zone and the average payout rate exceeds 100% when the game is played so as to pay out the maximum number of small winning coins, excluding the reels and the reel continuous operation device, but this is not limited to this. For example, the display unit may be configured to always display that the game is in a favorable zone when the game zone transitions to the favorable zone.

In the above embodiment, when the gaming zone transitions to a favorable zone, the zone control unit 114 is configured to display, via a display unit provided in the operation unit 30, that the gaming zone is a favorable zone, but this is not limited to this. For example, the liquid crystal display device 22 may be configured to double as the display unit, or the display unit may be omitted and configured not to display that the gaming zone is a favorable zone. After the display unit displays that the gaming zone is a favorable zone, it may or may not continue to display that the gaming zone is a favorable zone until the favorable zone ends.

Instead of a CPU that works with software to execute a specific function, the control device 100 may include an FPGA (field-programmable gate array) or an ASIC (application specific integrated circuit) that is specially designed to achieve a specific function using hardware alone.

The main control unit 110 and the sub-control unit 120 may be provided on different boards, or on the same board. That is, the main control unit 110 and the sub-control unit 120 may each have a CPU, ROM, RAM, etc., or may share a CPU, ROM, RAM, etc.

The push order role is not limited to winning by operating the stop switches 34, 35, and 36 in a predetermined push order. For example, the push order role may be won by operating the stop switches 34, 35, and 36 at a predetermined position, or may be won by operating the stop switches 34, 35, and 36 in a predetermined push order in addition to at a predetermined position.

The internal lottery table is not limited to the information shown in FIG. 9, but may include any other information depending on the design of the slot machine.

There must be at least one valid line, but there can be two or more.

If possible, the configuration of the main control unit 110 may be provided in the sub-control unit 120, or the configuration of the sub-control unit 120 may be provided in the main control unit 110.

In FIG. 1, an example is shown of a slot machine 1 in which the start switch 33 can be operated by actually inserting a medal, and medals are paid out to the lower tray 26 when the credits reach a specified value (for example, 50) or more or when the settlement switch is pressed. However, the present invention can also be applied to slot machines in which the start switch 33 can be operated without actually inserting a medal, and medals are not paid out to the lower tray 26. In this case, the slot machine does not need to be provided with a hopper unit 50, medals are paid out electronically rather than physically, and the paid-out medals are stored as data. In other words, the "game medium" in this specification is not limited to tangible objects such as medals, but also includes intangible objects such as data.

In addition, by appropriately combining any of the various embodiments or modifications described above, it is possible to achieve the effects of each. In addition, it is possible to combine embodiments with each other, or to combine examples with each other, and it is also possible to combine features of different embodiments or examples.
