Description

  The present invention is a game in which a player performs an operation of rotating and stopping a reel on the condition that a player bets a game medium such as a medal, and a game result such as winning is determined by a display mode of a symbol displayed by the stopped reel. Related to slot machines. In particular, the present invention relates to a slot machine that initializes a gaming state before a setting change with a setting change of a setting value corresponding to a winning lottery probability.

  2. Description of the Related Art Conventionally, as a gaming machine, there is known a slot machine that has a plurality of rotatable reels with symbols and that determines a game result such as winning by a display mode of symbols displayed by stopped reels. Such a slot machine is provided with a role lottery means for performing a lottery process for a winning combination, and the formation of the winning combination is confirmed when the symbols corresponding to the winning winning combination are aligned on the active line.

  The role of the slot machine game includes a small role that pays back a lot of medals when winning a prize according to the number of medals (game media) betted by the player, and the next game without consuming the medals bet by the player. There are replays (replays) that can be used. In addition, the conventional slot machines are provided with special game roles (RB role, BB role) for shifting to a special game state in which the winning probability of the small role is set higher than usual, and a gaming state advantageous to the player is provided. It can also be provided.

  In recent years, a plurality of gaming states (which are referred to as “RT states”) having different winning probabilities for re-gamers are provided, and for example, a slot in which the RT state transitions according to a predetermined condition such as display of a specific symbol or digestion of a finite number of games. A machine has also appeared. In the RT state, for example, when a transition is made to a general game in which the winning probability of the re-gamer is set higher than normal, it is possible to wait for the special gamer (RB role, BB role) to be won without reducing the game medium. As a result, it is advantageous to the player. A game state advantageous to the player also includes a specific game state such as an AT (assist time) that assists the player with a reel stop operation so that the winning combination is established. In this way, the slot machine makes various transitions such that various game states that are advantageous or disadvantageous to the player cannot be predicted, thereby creating waves in the game and preventing the player from getting bored. Furthermore, by setting a difference in the setting value (also called “machine discount” etc.) corresponding to the winning lottery probability for each slot machine, it is possible to predict and select the machine with the higher setting value. Moreover, it has become a major concern for players.

  The set values described above are usually in six stages (settings 1 to 6), and the higher the set value, the higher the probability of acquiring more medals. The change of the set value is performed by an administrator of a hall (a game hall for the purpose of game sales) or the like performing a predetermined procedure when the slot machine main power is turned on. Therefore, the set value is not directly known to the player. When the setting is changed, all the game information before the setting change is cleared by the initialization process that is subsequently started, and the game starts normally from the general game state.

  On the other hand, for example, in Patent Document 1, the RT state before setting is continued even after the setting is changed. On the other hand, if the bonus combination is won before the setting is changed, the winning is invalidated. There is disclosed a slot machine in which a game is continuously started using the same state and information even after the setting is changed without clearing the game state and game information of the part.

JP 2010-22605 A

  However, if the game state before the setting change is completely initialized by changing the setting of the slot machine as in the prior art, all the states advantageous to the player are lost. However, if the bonus change or the established special game state is restored by changing the setting, the change in setting will cause a large variation in the amount of medals expected by the hall, and the change in setting will result in The significance of the adjustment will be lost.

  In addition, it is possible to ensure a continuation of the game that is slightly advantageous to the player by continuing the game state in the general game instead of the special game state such as the RT state before the setting change as in Patent Document 1 after the setting change. It is. However, even if the RT state that should be accompanied by the privilege to execute a privilege such as an AT has continued, the inconsistency of the game state is caused in the continued game, such that the privilege disappears due to the setting change. There is also a case.

  The present invention has been made to solve such a conventional problem, and the object of the present invention is to provide a player with no game state inconsistency even when a set value is changed. It is an object of the present invention to provide a slot machine that can ensure execution of advantageous benefits.

  In order to solve the above-described problems, a slot machine according to the present invention includes a plurality of rotatable reels with symbols, main control means for controlling the progress of a game, and sub-control for controlling an effect device to execute an effect.

First, the structure of the slot machine (10) according to the present embodiment will be described with reference to the drawings.

[Front structure of slot machine]
FIG. 1 is a front view showing a front appearance of the slot machine 10. The slot machine 10 is pivotally supported by a front door 20 so that the opening can be opened and closed with respect to a housing that is a substantially rectangular box having an opening at the front. Normally, as shown in FIG. 1, the front door 20 is locked to the housing at a position where the opening is closed.

  The front door 20 is configured by a panel member that has a design that enhances the visual performance effect for the player. The panel member of the front door 20 is a game such as a central panel portion 30 which is a game area for mainly displaying the symbols of the reels 40L, 40C and 40R, and games such as rotation and stop of the reels below the central panel portion 30. An operation panel unit 50 in which switches for performing operations and the like are arranged, an upper panel unit 60 in which lamps, speakers, and the like mainly for gaming effects are arranged above the central panel unit 30, and an operation panel unit 50 A lower panel portion 70 on which characters and the like appearing in the game of the slot machine 10 are drawn is generally constituted below. The front door 20 is assembled by a panel member in which the central panel unit 30, the operation panel unit 50, the upper panel unit 60, the lower panel unit 70, and the like are unitized. Moreover, you may manufacture the front door 20 with one panel member by which these panel parts are comprised integrally.

  The middle panel 31 is provided with a middle panel 31 made of a resin plate such as hard acrylic. In the middle of the panel 31, a display window 32 composed of three rows of vertically-long rectangular transparent portions is formed. Through the display window 32, a total of nine frames of 3 rows x 3 frames vertically on the reels 40L, 40C, 40R inside the housing can be visually recognized.

  In the display window 32, five lines crossing the reels 40L, 40C, and 40R are set. The five lines include three horizontal lines (horizontal middle stage L1, horizontal upper stage L2A, horizontal lower stage L2B) and two diagonal lines (diagonal right-down L3A and diagonal right-up L3B). . As will be described in detail later, among these lines L1, L2A, L2B, L3A, and L3B, a winning determination is determined according to the number of medals that are betting media for the game (hereinafter referred to as “the number of bets”). A line (hereinafter referred to as “effective line”) is selected. When a symbol of a predetermined combination is stopped and displayed on a line selected as an active line, a combination corresponding to the combination of symbols (for example, a small combination that can acquire medals or a transition combination that shifts to another gaming state) Etc.) will be established.

  In addition to the display window 32, the middle panel 31 of the central panel unit 30 is provided with various lamps and a display for notifying the player of various information related to the game.

  The middle panel 31 is provided with, for example, three operation instruction lamps 33L, 33C, and 33R that are used in an AT state, which will be described later, adjacent to the display window 32 at the left end. These operation instruction lamps 33L, 33C, and 33R correspond to stop switches 56L, 56C, and 56R and reels 40L, 40C, and 40R, which will be described later, respectively. Such operation instruction lamps 33L, 33C, and 33R, for example, when the reels 40L, 40C, and 40R are rotating, any one of the operation instruction lamps is turned on, so that the player should be notified of the reel to be stopped. Can be notified. Further, if any two operation instruction lamps are turned on while all the reels 40L, 40C, and 40R are rotating, the reel to be stopped is one of two choices, and it is left to the player to select which one to stop. It is also possible to provide a game that can be applied.

  Further, at the lower part of the middle panel 31, three bet number display lamps 34a, 34b, 34c, a credit number display 35, and an obtained number display 36 are provided.

  The bet number display lamps 34a, 34b, and 34c are lamps that display the number of medals bet on the game. That is, when one medal is bet, only the bet number display lamp 34a is lit. When two medals are bet, the bet number display lamps 34a and 34b are lit. When three medals are bet, all bets are placed. The number display lamps 34a, 34b and 34c are lit.

  The credit number display 35 is a two-digit 7-segment numerical display, and displays the number of medals credited (stored internally) in the slot machine 10. The player can freely use and dispose of medals credited to the slot machine 10, and the number of credits is managed by the RAM of the main control board (100) described later.

  The acquired number display 36 is a two-digit 7-segment numerical display, and displays the number of medals to be paid out to the player when a winning is established in the game. Note that, as a mode of paying out medals by winning a prize, there are a case where credits are given to the inside of the slot machine 10 and a case where medals are directly discharged from a medal payout opening 71 described later.

  The operation panel 50 provided below the central panel 30 has a table-like surface 50a whose upper surface is slightly inclined, and a player inserts a medal into the slot machine 10 on the right side of the table-like surface 50a. A medal slot 51 is provided. Inside the medal insertion slot 51, a selector (28) for detecting inserted medals and distributing regular / non-regular medals is provided. The slot machine 10 recognizes the number of inserted medals by measuring the number of detection signals output from the selector (28).

  A 1-bet switch 52 and a max bet switch 54 are provided on the left side of the table-like surface 50a of the operation panel unit 50 for a player to give an instruction to bet medals from credits. When the 1-bet switch 52 is operated, one of medals credited to the slot machine 10 is bet on the game. When the max bet switch 54 is operated, three of the credited medals are bet on the game. When medals are bet by operating the 1-bet switch 52 or the max bet switch 54, the number of bet medals is subtracted from the credit, and accordingly, the display value of the credit number display 35 is also subtracted.

  When a player inserts a medal from the medal insertion slot 51 with no medals placed in the slot machine 10, the bet number display lamps 34a, 34b, 34c are sequentially turned on each time the medal is inserted. Medals according to the respective numbers are bet on the slot machine 10. Then, when the bet medals reach the maximum number of three, credits are added each time a medal is inserted thereafter, and accordingly, the display value of the credit number display 35 is also added.

  Here, in a game in which one medal is bet on the slot machine 10, for example, only the middle line L <b> 1 among the five lines described above is selected as an effective line as a reference for winning determination. In a game in which two medals are bet, for example, three horizontal lines L1, L2A, and L2B are selected as active lines among the five lines. In the game where the most three medals are bet, the four lines L1, L2A, L3A, and L3B except the lower line L2B are selected as effective lines and a winning determination is made. There is also a model that selects all lines including the lower line L2B as effective lines. As described above, in the game of the slot machine 10, the greater the number of medals bet, the greater the number of active lines, and the greater the chance of winning a prize by aligning symbols. Even if all the lines L1, L2A, L2B, L3A, and L3B are made effective regardless of the number of medals bet, and the chances of winning a prize can be increased by changing the winning probabilities according to the number of medals. Good.

  A start switch 55 having an operation knob that can be tilted is provided on the left side of the front surface of the operation panel 50. When the player operates the start switch 55 after betting medals on the slot machine 10, all the reels 40L, 40C, and 40R start to rotate at the same time. As a result, the symbols attached to the outer peripheral surfaces of the reels 40L, 40C, and 40R are displayed by moving (scrolling) from top to bottom through the display window 32.

  Three stop switches 56L for performing an operation for stopping the rotation of the reels 40L, 40C, and 40R by a player's pressing operation (this is referred to as a “stop operation”) at the center of the front surface of the operation panel 50. , 56C, 56R are provided. The left end stop switch 56L corresponds to the left end reel (left reel) 40L, the center stop switch 56C corresponds to the center reel (middle reel) 40C, and the right end stop switch 56R corresponds to the right end reel (right reel) 40R. It corresponds to.

  That is, in the slot machine 10, the reel 40L is stopped when the stop switch 56L is operated with respect to the reels 40L, 40C, and 40R rotated by the tilting operation of the start switch 55, and the reel 40C is stopped when the stop switch 56C is operated. When the stop switch 56R is operated, the reel 40R is configured to stop. The corresponding relationship between the reels 40L, 40C, and 40R and the stop switches 56L, 56C, and 56R is fixed and independent. In addition, when the reel (40L) stops when the stop switch (for example, 56L) is operated, the specified number of control frames (for example, five frames that follow from the symbol that passes through the display window 32 when the stop operation is accepted). Are controlled to always stop at the fixed positions of the horizontal lines L1, L2A, and L2B. The other two reels (40C, 40R) are similarly controlled to stop within the prescribed number of control frames when the stop switch (56C, 56R) is operated.

  Note that the reel 40L by the stop switches 56L, 56C, 56R until the constant speed rotation (for example, 80 rotations / min) is reached after the rotation of the reels 40L, 40C, 40R is triggered by the tilting operation of the start switch 55. , 40C, 40R is invalidated.

  The upper panel portion 60 positioned above the central panel portion 30 is provided with an image display device 61 formed of, for example, a color liquid crystal display at the central portion. The image display device 61 displays, for example, an animation developed as the game progresses as an effect image. The display device provided in the slot machine may not be the image display device 61 but may be a dot matrix display device, for example. Further, the game history and the internal lottery result information may be directly displayed with characters, symbols, or the like, or such information may be coded and displayed. That is, as the display device, any type of display means suitable for the application and purpose can be used.

  The upper panel portion 60 is provided with an upper lamp 62 and corner lamps 63L and 63R. For example, when the reels 40L, 40C, and 40R are stopped and any combination is established, the upper lamp 62 and the corner lamps 63L and 63R are turned on and blinked in a pattern corresponding to the combination, thereby establishing the combination. Produce visually.

  Further, the upper panel portion 60 is provided with sound transmission portions 64L and 64R through which output sounds from speakers (21L and 21R) disposed on the back side of the front door 20 are passed. For example, a stereo effect sound is output through the sound transmission parts 64L and 64R along with the effect image of the moving image displayed by the image display device 61.

  A medal payout outlet 71 and a tray 72 are provided in the lower panel portion 70 located below the central panel portion 30.

The ROM 102 also includes a stop operation order of the stop switches 56L, 56C, and 56R (also referred to as “operation stop order” or simply “push order”), a predetermined small role and re-playing role, and stop switches 56L and 56C. , 56R operation order table data associated with the stop operation order is also stored.

  Further, the RAM 103 (first storage means) of the main control board 100 stores data such as variables and various flags that are referred to in the process in which the CPU 101 performs the above-described program processing. For example, in addition to the number of credits described above, the number of bets placed in the game, the random number obtained for the winning lottery, the symbol number of the symbol stopped on the display window 32, and the winnings are paid out to the RAM 103. A variable memory area for temporarily storing variable data such as the number of medals and the number of games in a specific game state is set. Further, the RAM 103 is set with flag areas such as a winning combination flag indicating the result of the internal lottery, a winning combination flag indicating the established combination, and a flag indicating the gaming state of the game. As described above, the RAM 103 of the main control board 100 stores information related to the game operation state of the main control board 100, and the stored contents include the current game state such as the RT state described later and the role lottery means (502). ) Game result information is also included.

  The ports of the input circuit 104 are connected to switches such as the start switch 55, stop switches 56L, 56C, 56R, 1-bet switch 52, and max-bet switch 54 shown in FIG. A contact signal indicating the operation state of these switches is received by the input circuit 104 and input to the CPU 101 via the bus 105. Further, the display driver circuit 109 is connected to display units such as the bet number display lamps 34 a, 34 b, 34 c, the credit number display unit 35, and the acquired number display unit 36. The display drive circuit 109 lights the bet number display lamps 34a, 34b, 34c according to the bet number of medals bet by the 1-bet switch 52 or the max bet switch 54 or the like. Further, information data such as the number of credits stored in the RAM 103 and the number of medals paid out are encoded into segment codes by the display driver circuit 109 and displayed on the credit number display 35 and the acquired number display 36. The

  Also connected to the bus 105 are a motor drive control circuit 106, a rotational position detection circuit 107, a random number generator 108, and a signal transmission circuit 110.

  The motor drive control circuit 106 outputs drive pulse signals to the stepping motors 41L, 41C, 41R that drive the reels 40L, 40C, 40R, respectively, thereby rotating and stopping the reels 40L, 40C, 40R. To control. In this specification, the term “rotation control” includes control of rotation and stop of the reel.

  The rotational position detection circuit 107 receives a reference position signal output by the photosensors 42L, 42C, 42R provided in the reel unit 40 detecting and outputting the rotational reference positions of the reels 40L, 40C, 40R. Based on the number of pulses of the drive pulse signal output from the motor drive control circuit 106 as a reference, the current rotational positions of the reels 40L, 40C, and 40R are detected. Information on the rotational position of each reel 40L, 40C, 40R detected by the rotational position detection circuit 107 is stored and updated as needed in the reel control flag of the RAM 103 and managed by the CPU 101. Each of the photosensors 42L, 42C, and 42R is configured such that the light is shielded when the light shielding piece provided at the position of the symbol number “0” on the outer periphery of each reel 40L, 40C, and 40R passes through the sensor. Output position signal.

  The random number generator 108 outputs a random number value in the range of 0 to 65535 (16 bits), for example, when the start switch 55 is tilted. The role lottery means (502), which will be described later, includes the random number generator 108, and by referring to the role lottery table, a role corresponding to the winning value range to which the random number value obtained from the random number generator 108 belongs is won. Choose as. Instead of generating a random number by the hardware random number generator 108 as in the present embodiment, a random value may be obtained by so-called software random number processing based on arithmetic processing of the CPU 101. The lottery performed by the role lottery means (502) of the main control board 100 is referred to as “role lottery” or “internal lottery” in this specification.

  The main control board 100 outputs various commands such as a game state and an internal lottery result to the sub control board 200 connected via the signal transmission circuit 110.

[Sub-control board configuration]
Next, the sub-control board 200 that controls the game effects of the slot machine 10 will be described. FIG. 5 is a circuit block diagram showing a system configuration of the sub control board 200. Referring to the figure, a sub-control board 200 is connected to a CPU 201, a ROM 202, and a RAM 203 through a bus 205 so that they can communicate with each other. In addition, a signal receiving circuit 210, a lamp driving circuit 206, a speaker driving circuit 207, a display control circuit 208, and a random number generator 209 are electrically connected to the bus 205.

  The CPU 201 of the sub control board 200 receives various commands related to commands and game progress transmitted from the main control board 100 by the signal receiving circuit 210 and executes arithmetic processing according to programs stored in the ROM 202 according to these commands and the like. By doing so, the game machine is controlled mainly in the slot machine 10.

  The lamp driving circuit 206 is connected to lamps such as the upper lamp 62 and the corner lamps 63L and 63R shown in FIG. The lamp driving circuit 206 drives the lamps to light up and blink under the control of the CPU 201. The speaker driving circuit 207 is connected to the speakers 21L, 21R, 26L, and 26R shown in FIG. Under the control of the CPU 201, the speaker drive circuit 207 reads voice data such as announcements and musical sounds from the voice data memory 207a, converts them into sound signals, amplifies them, and based on the generated sound signals, the speakers 21L, 21R, 26L. , 26R.

  The display control circuit 208 is connected to the image display device 61 shown in FIG. The display control circuit 208 reads image data selected at any time from the image data memory 208a under the control of the CPU 201, generates a video signal in which a synchronization signal, a luminance signal, and a color signal are combined, and a moving image based on the video signal. Control to display an image on the image display device 61 is performed.

  The random number generator 209 outputs a random number value in the range of, for example, 0 to 65535 (16 bits) under the control of the CPU 201. The effect lottery means (610) described later of the sub-control board 200 includes the random number generator 209. Here, the effect lottery means (610) selects the effect pattern of the game effect referred to in the effect lottery table according to the random value acquired by the random number generator 209, for example. In addition, the effect lottery means (610) performs a lottery (whether a role notification lottery) whether or not to notify the player of the result of the internal lottery on the main control board 100, or a stop operation so that the winning combination is established. A lottery (AT lottery) of the right to perform AT assisting is also performed. Furthermore, a lottery such as winning / losing determination in another game of the player participation type performed in association with the original game of the slot machine 10 can also be performed.

  The effect lottery means (610) of the sub-control board 200 may perform lottery by so-called software random number processing based on arithmetic processing of the CPU 201 instead of the hardware random number generator 209 as in this embodiment. .

  The ROM 202 of the sub control board 200 stores an effect lottery table to be referred to in the effect lottery described above, in addition to the program executed by the CPU 201 and its initial data. On the other hand, in the RAM 203 (second storage means), a memory area for variables and flags to be referred to in the process of the CPU 201 of the sub-control board 200 performing the program processing is secured. That is, the RAM 203 stores information related to the operating state of the sub control board 200. Further, the RAM 203 also stores information including an execution right and an execution condition for executing an AT that is awarded when a special game combination with a bonus (BB1 combination), which will be described later, is won.

[Role and game status in slot machine games]
FIG. 6 is a diagram illustrating a combination of a combination in a game of the slot machine 10 of the present embodiment and a symbol corresponding to each combination. The correspondence between such a role and a symbol is managed by a symbol table stored in the ROM 102 of the main control board 100. The combination of the slot machine 10 is established when a symbol corresponding to the winning of the combination lottery means (502) described later is displayed on the active line. In this specification, the lottery performed by the role lottery means (502) described later is referred to as “role lottery” or “internal lottery”. Also, the winning state until the winning combination is won and established by the winning lottery means (502) is referred to as “internal winning” or simply “winning”. Special game actors (BB role, RB role), etc., which will be described later, can carry over the winning state over multiple games. Therefore, when “internally winning” or “winning” "State" is also included.

  As shown in FIG. 6, the role relating to the game of the slot machine 10 includes a “small role” in which more medals can be obtained than the medals bet by the player, and a “re-playing role in which the next game can be performed without betting medals. ("Replay role"), "special game role (RB role, BB role)" providing a game advantageous to the player.

  In the slot machine 10 according to the present embodiment, “small role 1” (2 payouts), “small role 2” (4 payouts), and “small role 3” are different as “small roles”. (5 payouts). Further, the small combination 2 includes a plurality of “small combination 2a”, “small combination 2b”, and “small combination 2c” to be won simultaneously. In the AT state to be described later, the AT execution means (620) of the sub-control board 200 operates any of the reels 40L, 40C, 40R to be stopped first in order to stop the symbol of the small role 2a on a predetermined effective line, for example. Any one of the instruction lamps 33L, 33C, and 33R is turned on for notification.

  Further, in the present embodiment, as the “re-game player”, a plurality of “re-game players a”, “re-game player b”, “re-game player c”, “re-game player d”, and “re-game player” are selected simultaneously. e "is provided.

  Further, the “special game player” is a role for transferring the game to the “special game” which is a game particularly advantageous for the player. In the present specification, games other than special games are referred to as “general games”.

  As the special game combination according to the present embodiment, “SB combination” to be transferred to “SB (single bonus) game”, “RB combination” to be transferred to “RB (regular bonus) game”, and “BB (big bonus) game”. "BB role" to be transferred to. The SB game is a high probability game in which a specific small role is won with a higher probability than a general game. An RB game is a gaming state in which such a high-probability game is continued a plurality of times, and continues until a predetermined number of games (for example, 12 games) are consumed or a small role is won a predetermined number of times (for example, 8 times). Refers to the game state. The BB game is a gaming state that continues until the above-mentioned RB combination is won with a specific small combination with a high probability during the general game, and a predetermined maximum payout number (for example, 480) of medals is paid out.

  Furthermore, the slot machine 10 of the present embodiment is provided with a plurality of types of BB combinations that are special game combinations. “BB1 role”, which is an example of the BB role, is a role that shifts to BB1 game when it is established and also grants the player the right to execute a privilege such as AT when winning by the role lottery means (502). is there. There is also a role in which the right to execute a privilege corresponding to the special role is determined at the same time that the special game character is established. Here, “privilege execution right” refers to a right that includes execution conditions such as a type of a bonus executed in the slot machine, a start condition, and an end condition. “Granting the privilege execution right to the player” means the same as “determining the privilege execution right” and, from the player's standpoint, “obtaining the privilege execution right”. When the privilege execution right is determined, the privilege is executed when the start condition defined in the right content is satisfied.

  In the present embodiment, a privilege to which an execution right is granted by winning the BB1 role is referred to as “AT”, and a state in which the AT is executed is referred to as an “AT state”. On the other hand, a state where the AT is not executed is referred to as a “non-AT state”. In the AT state, the AT execution means (620) of the sub-control board 200 is operated by the operation instruction lamps 33L, 33C, 33R, etc. so that a predetermined winning combination such as the small combination 2 drawn by the combination lottery means (502) is established. The player is notified of the first stop switch of the reels 40L, 40C, and 40R, the stop operation order, the symbols and patterns to be aimed, etc. using the image display device 61 and the like.

  Special game roles such as the BB1 role and the BB2 role, to which a privilege execution right is granted based on the winning by the role lottery means (502) of the main control board 100, in particular, are referred to as “special game player with privilege” in this specification. It is called. A plurality of special game combinations with benefits such as the BB1 role and the BB2 role may be provided, and the type of privilege and the execution conditions may be different depending on the type of the role. Note that the BB2 role in the special game combination with a privilege does not determine the privilege execution right at the time of winning by the role lottery means (502). However, for example, if the effect lottery means (610) of the sub-control board 200 wins the AT while the BB2 combination is won, the execution right corresponding to the AT is determined. Moreover, the right of execution of the corresponding AT privilege may be reset at the same time when the symbols of the BB1 role or the BB2 role are aligned and the special gamer with bonuses is established.

  As a condition for starting an award such as an AT, any special game (BB1, BB2, etc.) state may be continued after the end, or after a general game has elapsed a predetermined number of times after the special game state ends. Can be determined.

  FIG. 7A shows an example of a transition of the gaming state controlled by the main control board 100 of the slot machine 10 according to the present embodiment, and FIG. 7B shows an example of a transition of the effect state controlled by the sub control board 200. is there.

  Referring to FIG. 7A, the gaming state of the slot machine 10 is roughly divided into a “general gaming” state and a “special gaming” state in which an RB role or a BB role is established as described above. . Then, when divided from the viewpoint of the difference in the winning probability of the replaying role (replaying role), in the general gaming state, there are at least three further replaying role probability varying gaming states (referred to as “RT state”). To do. In other words, the game in the general gaming state is the “RT0” state where the winning probability of the re-gamer is relatively low, the “RT1” state where the winning probability of the re-gamer is relatively high, or these RT0 and RT1 states are It belongs to any one of the “RT2” states with different winning probabilities of gamers. In addition, you may provide multiple types of RT state from which the winning probability of a re-game player differs in addition to these.

  According to the embodiment of FIG. 7A, when a specific symbol combination, for example, a re-playing combination b is established in the RT0 state, a transition is made to the RT1 state with a high probability. Further, when a specific symbol combination, for example, a re-playing combination c is established in the RT1 state, the state transitions to the RT0 state. On the other hand, if a special game combination such as a BB combination is won internally in the general game state (which may be either RT0 or RT1), the game will further transition to the RT2 state where the winning probability of the re-game combination is different. It will be.

  Although not shown in the figure, the RT2 state in which an internal winning transition is made from the RT0 state and the RT2 state in which an internal winning transition is made from the RT1 state are distinguished from each other as different RT states having different winning probabilities of re-game players. Also good. Further, the transition condition from the RT1 state having a relatively high winning probability of the re-gamer to the RT0 state having a relatively low winning probability may be set as a finite condition as after a predetermined number of games have elapsed. Furthermore, another RT state may be added to the embodiment of FIG. 7A, or a change such as adding a display of a specific symbol or missing a specific role to the transition condition of the RT state may be arbitrary.

  Further, from the viewpoint of the effect state of the slot machine 10, the ongoing game state belongs to any effect state of the non-AT state or the AT state shown in FIG. 7B. According to the embodiment of FIG. 7B, for example, when the effect lottery means (610) of the sub-control board 200 wins an AT, the transition to the AT state is made when a start condition corresponding to the winning AT is satisfied. In the present embodiment, when the right to execute the AT privilege is determined based on the above-described winning of the BB1 role, the state transitions to the AT state upon completion of the BB1 game. It is also possible to transition to the AT state at the same time as the AT win without setting the AT start condition.

  According to the embodiment of FIG. 7 (b), when the game in the AT state is consumed a predetermined number of times, the AT state ends and transitions to the non-AT state. As the number of games in which the AT state continues, for example, 30 games can be set as one set. Alternatively, the execution right by AT winning may be stocked, and the AT state may be continued for the number of times of the stocked set. The effect lottery means (610) may perform an AT lottery during the AT state. If the AT wins during the AT state, another set (for example, 30 games) of the AT gaming state continues.

  The contents of the AT privilege execution right granted based on the winning of the BB1 role or the BB2 role described above include the number of games of the one set. In addition, the number of stocks of the set (the number of times the AT state continues) may be included in the content of the right to execute the AT privilege. Further, the probability that the AT continues to execute another set after the end of one set (this is referred to as “AT continuation rate”) may be included in the contents of the AT privilege execution right. Note that “AT privilege execution right is granted” means specific values for parameters such as the AT set number variable 653, the AT game number counter 654, and the AT continuation rate setting value variable 655 in the RAM 203 of the sub-control board 200. Is stored.

[Control means and operation of slot machine]
Next, the control means provided in the slot machine 10 according to the present embodiment and the operation thereof will be described. Here, FIG. 8 is a block diagram showing an outline of the control means in the slot machine 10.

  The overall control in the slot machine 10 is performed by the cooperation of the control means provided in the main control board 100 and the sub control board 200 described above. Each control unit referred to in FIG. 8 is realized by the CPU 101 of the main control board 100 and the CPU 201 of the sub-control board 200 performing arithmetic processing, but some of them can be configured by hardware.

(Game control means)
First, the game control means 500 provided on the main control board 100 as the main control means controls the progress of the game performed in the slot machine 10 by supervising each control means described below. The game control means 500 is generated by calling a subroutine, the bet number setting means 501, the winning lottery means 502, the reel rotation control means 503, the winning determination means 504, the medal payout control means 505, and the update process. Means 506.

  FIG. 9 is a flowchart corresponding to a unit game executed in the slot machine 10 and shows a flow of game control processing executed by the game control means 500.

(Bet number setting means)
In the standby state for starting the game, the betting number setting means 501 is activated (step S10). Here, the game start standby state is a state after the reels 40L, 40C, and 40R are stopped and the winning determination is made, and waiting for the next bet operation. FIG. 10 is a flowchart showing bet number setting processing by the bet number setting means 501.

  Referring to FIG. 10, betting number setting means 501 determines whether or not a winning combination flag 582 relating to a re-game combination is set in the game (step S101). When the winning combination flag 582 related to the re-game is set on (step S101: YES), the winning combination flag 582 is cleared to off (step S102), and the subsequent game processing is performed. Note that the winning combination flag 582 related to the re-gamer is set to ON when the winning determination means 504 described later determines that the re-gamer has been established in the previous game (step S166 in FIG. 18). As a result, in a game in which a re-game role is established, it becomes possible to re-play with a medal bet on the previous game.

  The betting number setting means 501 does not set the winning combination flag 582 relating to the re-gamer in the game (step S101: NO), and detects the operation of the 1-bet switch 52 (step S103: YES), the credit If there is any (step S104: YES), “1” is subtracted from the credit number variable 552 (step S105). Then, “1” is added to the bet number variable 561 (step S107).

  When the selector 28 detects the insertion of a regular medal in the game start standby state (step S106: YES), the bet number variable 561 is added every time the inserted medal is detected (step S107). The bet number variable 561 is added (step S107) until the bet number of medals reaches an arbitrary prescribed number desired by the player (maximum “3”) (step S108: YES).

  In addition, when the bet number setting means 501 detects the operation of the max bet switch 54 (step S103: YES), if there is a credit (step S104: YES), “3” is subtracted from the credit number variable 552 (step S103: YES). S105), the bet number variable 561 is set to “3” (step S107).

  The game control means 500 sets an effective line according to the prescribed number of medals finally bet. That is, when the value (the number of bets) of the bet number variable 561 is “1”, one line L1 is set as an effective line, and when the bet number is “2”, the three lines L1, L2A, and L2B are set. When the number of bets is “3”, the four lines L1, L2A, L3A, and L3B are set as valid lines.

  Referring to FIG. 9 again, when the start switch 55 is tilted and detected to be on in the state where the bet number of medals has reached the specified number, the game control means 500 starts the rotation of the command transmission means 510 (step S11: YES). A command is transmitted to the sub control board 200 (step S12).

(Role lottery means)
Next, the role lottery means 502 will be described. The role lottery means 502 performs lottery table lottery based on the random number value acquired from the random number generator 108 in step S13 (see FIG. 9) of the game control process triggered by the operation of the start switch 55.

  FIG. 11 shows an example of a typical role lottery table referred to by the role lottery means 502 for determination of winning / non-selection of a role in a general game (for example, in the RT0 state). According to the embodiment of FIG. 11, when the random number value acquired from the random number generator 108 belongs to the winning value range (lottery result numbers 9 to 14) of the re-game player, the re-game player corresponding to the winning value range. Won. Further, when the random number belongs to the winning numerical value range (lottery result numbers 4 to 8) of the small combination, the small combination corresponding to the winning numerical value range is won. Similarly, when the random number belongs to the winning numerical value range (lottery result number 3) of the RB role, the RB role is won, and when the random number belongs to the winning numerical value range (lottery result number 1 to 2) of the BB role BB role is won.

  Note that FIG. 11 is an example showing an RT0 state combination lottery table in which the winning probability of a re-game combination is about 1 / 7.3, and a general game (for example, RT1, RT2 state, etc.) in which the RT state has transitioned or a special game In the gaming state, a combination lottery table with different lottery probabilities is used.

  The role lottery means 502 also performs lottery in the order of stop operations as follows. FIG. 12 is a diagram illustrating the association between the small role and the stop operation order. FIG. 13 is a diagram illustrating the association between the re-game player and the stop operation order. Although not shown in detail in FIG. 11, in the winning numerical value range (lottery result numbers 5 to 7) of the small combination 2, a plurality of combinations of the small combination 2a, the small combination 2b, and the small combination 2c to be simultaneously won are included. Each is associated. Similarly, the winning numerical value range (lottery result numbers 9 to 14) of the re-game player includes a plurality of re-game players a, re-game player b, re-game player c, re-game player d, and re-game player e that are simultaneously won. The combinations of re-game players are associated with each other.

  For example, if the result of the lottery result number 6 is a random number lottery by the combination lottery means 502, the small combinations 2a and 2c are internally won simultaneously. In this case, the first stop operation is set as the correct answer by pressing the middle (stop switch 56C), and the first stop operation is set as the incorrect answer by pressing the left or right (stop switches 56L, 56R). Here, when the five lines L1, L2A, L2B, L3A, and L3B are set as effective lines, the reel rotation control means 503, which will be described later, pulls in and controls the symbols as described below. When the middle stop switch 56C is first operated in the winning of the lottery result number 6 (push order correct answer), the “bell” symbol of the corresponding middle reel 40C is drawn into the middle effective line L1 and the small role 2a is won. Let In this case, a total of 12 medals are paid out by payout 4 × 3 lines of the small combination 2a. On the other hand, when the left (stop switch 56L) or right (stop switch 56R) is first operated (incorrect pressing order), the reel rotation control means 503 draws the “bell” symbol into the upper effective line L2A. . As a result, a total of four medals of 4 payouts × 1 line are paid out, but the number of medals to be acquired is smaller than in the case of the correct push order.

  As shown in FIG. 13, for example, if the result of the lottery result number 9 is a random number lottery by the role lottery means 502, the replays a, b, and c are won simultaneously. In this case, the pressing order for establishing the re-gamer b is the operation order 1 (left → middle → right). Note that the re-game player b is also a specific symbol role that can be a trigger for transition to RT1, which is the high-probability re-game player probability variation game state shown in FIG. In addition, in the general gaming state of RT1 shown in the embodiment of FIG. 7, although not shown, a role lottery table associated with a pressing order for drawing a regame character a or c is used. Depending on the case, the symbol of the re-playing combination c that triggers the transition from RT1 to RT0 may be displayed.

  FIG. 14 is a flowchart showing a role lottery process (details of step S13 in the game control process of FIG. 9) by the role lottery means 502. In the process shown in FIG. 14, the winning lottery means 502 acquires the random value indicated by the random number generator 108 at the falling timing of the ON switch signal of the start switch 55, for example (step S131), and the acquired random value is stored in the RAM 103. Are stored in the random value variable 562. Here, the random number generator 108 is composed of, for example, a 16-bit increment counter that operates with a clock, and outputs a numerical value of “0” to “65535”.

  Then, the winning lottery means 502 refers to the winning lottery table stored in the ROM 102 and selects a winning combination corresponding to the winning numerical range to which the acquired random number value belongs as the winning winning combination. That is, if the acquired random number value belongs to the winning numerical value range of the small role, the winning of the small role is determined (step S132: YES), and the winning combination flag 581 related to the selected small role is set to ON (step S133). . The winning combination flag 581 is a flag for storing the type of the winning combination in the internal winning combination. The winning combination flag 581 is set to ON by winning by the winning lottery means 502 and cleared to OFF when the winning combination is established (winning).

  Further, if the acquired random number value belongs to the winning numerical value range of the re-gamer (step S135: YES), the winning lottery means 502 sets the winning combination flag 581 relating to the winning re-gamer to ON (step S136). ).

  If the acquired random number value belongs to the winning numerical value range of the BB role, the role lottery means 502 determines that the BB role is won (step S138: YES), and sets the winning combination flag 581 related to the winning BB role to ON. (Step S139). Similarly, when the winning combination of the RB combination is determined (step S140: YES), the winning combination flag 581 related to the RB combination is set to ON (step S141).

  In step S14 of the game control process referred to in FIG. 9, the command transmission means 510 sub-controls the part lottery result command indicating the result of the part lottery by the part lottery unit 502 (including the association between the part and the stop operation order). Transmit to the substrate 200.

(Reel rotation control means)
Next, the reel rotation control means 503 will be described. In step S15 (see FIG. 9) of the game control process, the reel rotation control means 503 controls the rotation and stop of the reels 40L, 40C, and 40R according to instructions from the start switch 55 and the stop switches 56L, 56C, and 56R. To do. Here, FIG. 15 is a flowchart showing a reel rotation control process by the reel rotation control means 503.

  When the reel rotation control means 503 detects a tilting operation of the start switch 55 in a state where medals are bet on the game, the motor drive control circuit 106 outputs a drive pulse signal to the stepping motors 41L, 41C, 41R. Thus, acceleration control is performed to rotate the reels 40L, 40C, and 40R all at once (step S151). Then, the reel rotation control means 503, when the rotation speed of each of the reels 40L, 40C, 40R reaches, for example, 80 rotations / min (step S152: YES), the reels 40L, 40C, While detecting the rotational state of 40R, constant speed control is performed at the rotational speed (step S152).

  The reel rotation control means 503 controls the rotation of the reels 40L, 40C, 40R at a constant speed (step S152: YES), and detects a stop operation signal from any of the stop switches 56L, 56C, 56R (step S153: YES). ), A rotation stop command indicating the stop operation is transmitted to the sub control board 200 by the command transmission means 510 (step S154). The reel rotation control unit 503 slides the reels 40L, 40C, and 40R corresponding to the stop operation within a predetermined time (for example, 190 msec) and within a specified number of control frames (for example, 5 frames). Then, symbol stop control for stopping at the effective line is performed via the motor drive control circuit 106 (step S155).

  The reel rotation control unit 503 stops the reels corresponding to the stop operation of the stop switches 56L, 56C, and 56R until all the reels 40L, 40C, and 40R are stopped (step S156: YES). The control of steps S153 to S155 I do. When the stop of all the reels 40L, 40C, 40R is detected (step S156: YES), the process is returned to the game control means 500.

  In the symbol stop control in step S155 shown in FIG. 15, in detail, the reel rotation control means 503 determines in advance the symbol to be stopped on the line L1 of the display window 32. For example, when the pressing operation of the stop switch 56L is detected while the central reel 40L rotates at a constant speed, the symbol number X of the symbol passing through the middle line L1 is acquired. In this case, the symbols of the symbol numbers X + 1, X + 2, X + 3, X + 4, and X + 5 of the following five frames from the symbol passing through the line L1 are recognized as candidates to be stopped on the line L1. The reel rotation control means 503 refers to the symbol number table in the ROM 102, the symbol symbol table, and the winning symbol flag 581 for storing the result of the internal lottery. It is checked whether or not the corresponding symbol exists in the symbols of symbol numbers X to X + 5. If there is a symbol corresponding to the winning combination, the symbol is determined as a target of “pull-in control” for stopping the symbol on the line L1.

  Here, FIGS. 16A and 16B are diagrams for explaining an operation example of the pull-in control. The reel rotation control unit 503 sets the stop control flag 563 of the RAM 103 according to the lottery result by the combination lottery unit 502. For example, as shown in FIG. 16, the stop control flag 563 has a flag array in which the number of sliding symbols is associated with each symbol number, and is provided for each of the reels 40L, 40C, and 40R.

  For example, when a small role corresponding to the symbol “Bell” is won internally and the push order is associated, the symbol to be drawn into the center line L1 (effective line) when the push order is correct is controlled. Is "bell". For each symbol number of the stop control flag 563, the reel rotation control means 503 stops the difference in the number of frames from the position of the symbol number to the symbol of the “bell” that is first arranged in the reel rotation direction as the number of sliding symbols. The control flag 563 is set. The stop control flag 563 is set as needed according to the type of symbols displayed when the winning combination is drawn and when other reels are stopped, and the original data is stored in the ROM 102 in advance.

  FIG. 16A shows a stop control flag 563 for the middle reel 40 </ b> C that is set when the small combination 2 a corresponding to the symbol “Bell” is won internally and the pressing order is correct. In this example, the symbol “bell” is arranged at intervals of 5 frames or less on the middle reel 40C, so that it can be reliably stopped at the effective line at any stop operation timing, and is a so-called non-missing symbol. FIG. 16B shows a stop control flag 563 that is set when the pressing order is incorrect.

  For example, when the “bell” small role 2a is won internally, for example, while the “replay” symbol of the symbol number “13” is passing through the middle line L1, the stop switch 56C is pressed in the correct pressing order associated by the above-mentioned role lottery means 502. When the stop operation is accepted, the stop control flag 563 for the correct push order is set as shown in FIG. The reel rotation control means 503 refers to the set stop control flag 563 and adds the “bell” symbol of the symbol number “16” to which the number of sliding symbols “3” corresponding to the symbol number “13” is added to three symbols. It is determined as an object of pull-in control to the middle line L1 where the effective lines intersect. Then, the reel rotation control means 503 stops and controls the reel 40C so that the “bell” symbol of the symbol number “16” is displayed on the line L1. When the small role 2a related to “Bell” wins in the middle active line (line L1), the player can obtain a total of 12 medals of 4 payouts × 3 lines.

  Also, for example, if the stop switch 56C is stopped in the order of pressing the wrong answer while the “replay” symbol of the symbol number “13” is passing through the middle line L1, as shown in FIG. The order incorrect answer stop control flag 563 is set. In this case, control is performed so that the “bell” symbol of symbol number “16” is drawn into one effective line (line L2A) in the upper stage. Thus, when the pushing order is incorrect, the “bell” symbol related to the small role 2a stops at the upper active line (line L2A), so that the player can pay a total of four payouts × 1 line. Only medals can be obtained.

  In the symbol stop control in step S155 shown in FIG. 15, the symbol corresponding to the winning combination indicated by the winning combination flag 581 does not exist in the symbol numbers X to X + 5, or the winning combination flag 581 is In the case of a losing that does not show the winning combination, a symbol related to the winning of the symbol number X to X + 5 of the reel 40L (including a single winning symbol such as “cherry” of the small role 1) is on the active line. It is controlled not to be displayed. In this case, if the other reels 40L and 40R are already stopped, the reel rotation control means 503 also considers the relationship (reach display mode etc.) with the symbols of the other reels displayed on the effective line. In this way, the control for removing the symbol related to the winning combination from the effective line and stopping it is called “kicking control”.

  FIGS. 17A and 17B are diagrams for explaining an operation example of kicking control by the reel rotation control means 503. FIG. In the present embodiment, for example, when the symbol “bell” of the middle reel 40C stops on the active line, the small role 2a wins (see FIG. 6). It is necessary to prevent the “bell” symbol from being displayed on the active line. For example, when the effective line of the slot machine 10 is set to five, the reel rotation control means 503 rotates the reel from the position of the symbol number for each symbol number of the stop control flag 563 shown in FIG. The difference in the number of frames until the symbol “bell” placed first in the direction deviates from the frame of the display window 32 is set in the stop control flag 563 as the number of sliding frames.

  In the example of FIG. 17A, when the reel rotation control means 503 receives a stop operation of the stop switch 56C while the “watermelon” symbol of the symbol number “14” is passing through the line L1, for example, the reel rotation control means 503 refers to the stop control flag 563. Then, the “cherry” symbol of the symbol number “18” obtained by adding the number of sliding symbols “4” to the symbol number “14” is determined as the symbol to be stopped on the middle line L1. At this time, the value of the symbol number “18” is set in the stop symbol flag. Then, the reel rotation control means 503 stops the reel 40C by the above-described method, and displays the “cherry” symbol of the symbol number “18” on the middle line L1. At this time, the “bell” symbol (symbol number “16”) related to the winning is stopped at a position that has passed through the display window 32, and thus deviates from a predetermined effective line.

  Further, when the effective lines are set to four lines excluding the lower line L2B, the stop control flag 563 shown in FIG. 17B is set for the middle reel 40C. For example, when the stop switch 56C is stopped while the “watermelon” symbol of symbol number “14” passes through the middle line L1, the “bell” symbol of symbol number “16” is changed to the lower line L2B (invalid line). Controlled to be drawn. At this time, the “bell” symbol (symbol number “16”) related to the winning is stopped on the lower invalid line (line L2B), and thus deviates from the predetermined valid line.

(Winning determination means)
Next, the winning determination means 504 will be described. The winning determination means 504 is activated when all the reels 40L, 40C, 40R are stopped in step S16 (see FIG. 9) of the game control process. FIG. 18 is a flowchart showing a winning determination process by the winning determination means 504.

  The winning determination unit 504 first clears and initializes the winning combination flags 582 for all the combinations managed by the RAM 103 (step S161). Subsequently, the winning determination unit 504 refers to the reel control flag of the RAM 103 for each of the reels 40L, 40C, and 40R, and recognizes the symbol displayed on the active line (step S162). The winning determination means 504 may recognize the symbols on the effective line based on the integrated value of the number of drive pulse signals sent from the reel rotation reference position.

  Further, the winning determination means 504 refers to the role symbol table and checks whether or not the symbol combination of the reels 40L, 40C, and 40R displayed along the active line matches the combination corresponding to any role. . The winning determination means 504 determines that the corresponding combination is established (winning) when the symbol display mode matches the combination of symbols corresponding to any combination.

  For example, when the winning determination means 504 determines that a small combination has been established (step S163: YES), the winning combination flag 582 relating to the small combination is set on (step S164). Further, when it is determined that the re-gamer is established (step S165: YES), the established combination flag 582 related to the re-gamer is set to ON (step S166). For example, when the winning determination means 504 determines that the BB combination is established (step S167: YES), the winning combination flag 582 related to the BB combination is set to ON (step S168), and the BB state flag 585 is set to ON. (Step S169). Similarly, when it is determined that the RB combination is established (step S170: YES), the established combination flag 582 related to the RB combination is set to ON (step S171), and the RB state flag 584 is set to ON (step S172). ).

  When the winning determination means 504 determines that any of the small combination, replay combination (replay combination) or special game combination (BB combination, RB combination) is established, the winning combination flag 581 of the established combination is determined. Is cleared (step S173). On the other hand, when a small role, a replaying role or a specific symbol role that cannot be carried over other than the special game role is an internal winning game, and these games are missed, the winning flag 581 is cleared ( Step S174).

  Information on the result of the winning determination by the winning determination means 504 is transmitted to the sub-control board 200 as a prize determination result command by the command transmission means 510 (step S17 in FIG. 9).

(Medal payout control means)
Next, in step S18 of the game control process shown in FIG. 9, the medal payout control unit 505 is activated when the winning determination unit 504 determines, for example, the winning of a small role. Here, FIG. 19 is a flowchart showing a medal payout control process by the medal payout control means 505.

  There are two methods for paying out medals to be paid to a player when winning a small role: internal storage as credits, and payment of medals from a medal payout outlet 71 to a tray 72. In the slot machine 10 according to the present embodiment, priority is given to internal storage in credits. That is, normally, the number of medals to be paid out is added to the credit, but when the added credit exceeds a predetermined upper limit (for example, 50), medals corresponding to the surplus are discharged from the medal payout opening 71.

  When the medal payout control means 505 wins a small combination, the medal payout number obtained by multiplying the number of active lines with the symbols by the number of payouts corresponding to the winning small combination is calculated as a payout number counter 571 (hereinafter, “ PCNT ") (step S181). If PCNT is greater than or equal to zero in step S182, that is, if there is a payout (step S182: YES), it is determined whether or not the credit number variable 552 is the upper limit (full) of 50 cards (step S183).

  When the credit number variable 552 is full (step S183: YES), the medal payout control means 505 operates the medal payout device 83 to release one medal (step S184). Then, PCNT is subtracted by “1” (step S186), and the process returns to step S182. When the credit number variable 552 is not full (step S183: NO), the medal payout control means 505 adds “1” to the credit number variable 552 (step S185) and subtracts PCNT by “1” (step S186). Then, the process returns to step S182. The medal payout control means 505 repeats the steps S182 to S186 for paying out medals one by one in this way until PCNT becomes zero.

(Update processing means)
Next, the update processing unit 506 will be described. The update processing means 506 performs an update process including a transition to the next game in step S19 (see FIG. 9) in the game control process. Here, FIG. 20 is a flowchart showing processing by the update processing means 506.

  When the BB state flag 585 related to the BB game is ON (step S191: YES), the update processing means 506 adds the number of medals paid out by winning in the game to a total payout counter 574 (hereinafter referred to as “DCNT”). (Step S192). When the DCNT exceeds, for example, 480 cards corresponding to the maximum payout number that is a BB game end condition (step S193: YES), the BB state flag 585 related to the BB game is turned off (step S194), and the DCNT is changed. Clear (step S195).

  When the RB state flag 584 related to the RB game is on (step S196: YES), the update processing unit 506 adds “1” to the game number counter 572 (hereinafter “GCNT”) (step S197). Further, when a small combination is established in the game and the formed combination flag 582 is ON (step S198: YES), “1” is added to the small combination winning number counter 573 (hereinafter “WCNT”) (step S199).

  When the GCNT corresponding to the number of RB games exceeds, for example, 12 games, or when the WCNT corresponding to the number of established small roles exceeds, for example, 8 times (step S200: YES), the update processing unit 506 The flag 584 is turned off (step S201), and GCNT and WCNT are cleared (step S202).

  When the game state is changed between RT0 to RT2 or the general game and the special game described above with reference to the flag relating to the game state (step S203: YES), the update processing unit 506 changes the game state. The combination lottery table corresponding to is read from the ROM 102 and set in the combination lottery means 502 (step S204).

(Power interruption recovery means)
Next, the power interruption first return means 520 provided in the main control board 100 shown in FIG. 8 and the power interruption second return means 630 provided in the sub control board 200 will be described. In the slot machine 10, the operating state before the power interruption is reproduced as it is after the power is turned on. FIG. 21 is a table showing an example of the operating state before and after the power interruption of the main control board 100 and the sub control board 200.

  In the shutdown process when the main power switch of the slot machine 10 is shut off, the power-off first return means 520 of the main control board 100 includes the stored contents of the register of the CPU 101 of the main control board 100 and the left table of FIG. The parameter values of the RAM 103 shown in FIG. Similarly, the power interruption second return means 630 of the sub control board 200 saves the stored contents of the register of the CPU 201 of the sub control board 200 and the contents of the RAM 203 shown in the right table of FIG. 21 in the sub stack area. The main-side and sub-side stack areas are provided in storage areas in which stored contents are held for a long time by a backup power source. Such a stack area may be provided in a nonvolatile memory that does not require a holding power source such as a flash memory.

  The power-off first return means 520 and the power-off second return means 630 return the stored contents of the stack area to the respective addresses before power-on in the process at the time of power-on to the slot machine 10. Accordingly, as shown in FIG. 21, in the main control board 100, system variables such as setting values and credits corresponding to the winning lottery probability, temporary variables such as bet numbers and random numbers for lottery, winning combination flags All game information before power interruption such as a flag relating to a game state such as an RT state flag is maintained. Further, in the sub-control board 200, the performance state such as the performance pattern variable and the AT state flag, and the right to execute the AT privilege that existed before the power interruption (that is, when the value of the AT set number variable 653 is 1 or more) Are all maintained. Thereby, the same situation as before the power interruption is reproduced after the power is turned on, and the game continues under the same conditions.

  In another embodiment, the stored contents of the RAMs 103 and 203 before power interruption are retained in the state of power interruption by a backup power source or the like even during power interruption. Even in this embodiment, as shown in FIG. 21, the stored contents of each memory are maintained before and after the power interruption, so that the main control board 100 and the sub control board 200 continue the gaming state at the time of the power interruption. The game and effect control can be resumed.

(Setting change means)
Next, the setting change means 530 for changing the set value corresponding to the winning lottery probability shown in FIG. 8 will be described. The setting changing means 530 provided in the main control board 100 is activated only when a predetermined setting key switch is operated when the main power of the slot machine 10 is turned on. The setting key switch is provided inside the housing 80 of the slot machine 10, and only a limited person such as a hall manager can change the setting. Therefore, the set value is not directly known to the player.

  This set value has six stages of settings 1 to 6, and the higher this set value, the higher the probability of acquiring a medal, which is advantageous to the player. The setting change means 530 causes an operator (such as a hall manager) to select one of the setting values 1 to 6 by a setting key switch selection operation, and determines the setting value by a determination operation. Then, the determined set value is stored in the set value variable 551 of the RAM 103. By storing the setting value in the public area of the RAM 103, the winning lottery means 502 can refer to the changed setting value.

(Initialization means when changing settings)
Subsequent to the processing of the setting change means 530, the first initialization means 540 at the time of setting change on the main control board 100 side is activated. The first initialization means 540 at the time of setting change initializes the operating state of the main control board 100 except for a part. After the initialization process on the main control board 100 side is completed, the second initialization means 640 is activated at the time of setting change on the sub control board 200 side. The second initialization means 640 at the time of setting change initializes the operation state of the sub-control board 200 except for a part. It should be noted that the initialization process on the sub-control board 200 side by the second initialization means 640 at the time of setting change is performed in accordance with the initialization process on the main control board 100 side by the first initialization means 540 at the time of setting change. It may be. Here, FIG. 22 shows a table showing the initialization state of the operation state in the main control board 100 and the sub control board 200 according to the setting change.

  As described above, since the setting value is changed when the main power supply of the slot machine 10 is turned on, the parameter variable value and the flag value that define the operation state before the power interruption are stored in the memory stack area when the setting is changed. Is in a state of being evacuated. Alternatively, in another embodiment, parameter variables at the time of power interruption are stored in the RAMs 103 and 203.

  When the setting of the main control board 100 is changed, the first initialization unit 540 sets an initial value (default value) defined in advance in the parameter storage area of the RAM 103. Similarly, the second initialization unit 640 at the time of setting change of the sub control board 200 sets a default value in the parameter storage area of the RAM 203. Specifically, as shown in FIG. 22, most variables such as the number of credits, the number of bets, and other counter variables are initialized, and “0” is set as the initial value.

  However, when the setting is changed, the first initialization unit 540 does not initialize the winning combination flag and the RT state flag among the state flags of the RAM 103 of the main control board 100 in accordance with the change of the setting value. Restore the stacked value. Alternatively, in another embodiment, the winning combination flag and the RT state flag at the time of power interruption are maintained as they are. As a result, the RT state to which the game before the setting value was changed and the winning state such as a special game player are also reproduced in the game after the setting change. As shown in FIG. 22, except for the RT state of the general game managed by the main control board 100, information such as the RB state or the BB state, which is the special game state, is initialized as the set value is changed. In this initialization process, only the winning state of a winning combination that can be carried over among the winning combination flags managed by the main control board 100 is maintained, and the winning state of a winning combination (such as a small role) that cannot be carried over is initialized. You may do it. It is also possible to limit the period during which the setting can be changed (assuming that the setting cannot be changed during a period in which no game is played or a period in which the game is in a special game state). Further, the second initialization unit 640 at the time of changing the setting of the sub control board 200 initializes most of the variables in the RAM 203. Thereby, information such as the effect pattern and AT state managed by the sub-control board 200 is initialized.

(Production control means)
Next, various control means provided on the sub control board 200 as the sub control means shown in FIG. 8 will be described. The effect control means 600 provided in the sub-control board 200 mainly controls the effects performed in association with the progress of the game of the slot machine 10 together with the control means described below.

  The effect control means 600 generates effects by using lights such as the upper lamp 62, corner lamps 63L, 63R, speakers 21L, 21R, and the like according to the content and timing of commands transmitted from the main control board 100. An effect by sound using 26L and 26R, and an effect by image or character using the image display device 61 are controlled.

  For example, when the start switch 55 is tilted and the rotation start command (step S12 in FIG. 9) is received from the main control board 100, the effect control means 600 displays a predetermined or any time-selected effect image on the image display device 61. Thus, an effect that attracts the player's interest in the rotation of the reel is performed. The effect control means 600 selects an effect pattern to be effected on the image display device 61 or the like in accordance with the result of the lottery executed by the main control board 100 and the current game state. Further, the effect lottery means 610 described next may select effect images and effect patterns by lottery. Information on the selected effect pattern is stored in the effect pattern variable 651 of the RAM 203.

  Further, the production control means 600 confirms the existence of the right to execute the AT privilege corresponding to the special gamer with a bonus such as the BB1 role or the BB2 role, and stores the information in the RAM 203. Remember and reset. Here, FIG. 23 is a flowchart showing the flow of the entire process until the execution privilege of the AT privilege is reset when the special gamer with privilege is established.

  According to the embodiment of FIG. 23, during the game of the slot machine 10, when a special game player with a bonus is won by the role lottery means 502 (step S210), the right to execute the AT privilege is determined based on the win. Are set in the RAM 203 (step S211). Here, “based on the winning of the special gamer with bonus” means that the right to execute the AT privilege is set when the winning lottery means 502 is selected as the BB1 role, or the winning is as the BB2 role. The execution right is not fixed at the time, but the manner and timing in which the process of step S211 is performed are various, such as when the execution right is set in the AT lottery performed by the effect lottery means 610 described later after winning.

  As a specific example of the AT execution right information set in step S211, for example, “1” is set in the AT set number variable 653 of the RAM 203, and the AT game number counter 654 and the AT continuation rate setting value variable 655 are set. A value corresponding to the special gamer with bonus is set. Here, the parameters such as the AT game number counter 654 and the AT continuation rate setting value variable 655 determine the end condition of the AT state. If the number of sets already stocked in the AT set number variable 653 is one or more, “1” may be added to the stocked set number when setting the AT execution right.

  When the game of the slot machine 10 progresses and a special game combination with benefits is displayed and a combination is established (step S212), a command to establish a combination from the main control board 100 to the sub-control board 200 (winning determination result command) Is sent. Upon receiving this command, the effect control means 600 of the sub-control board 200 checks whether or not the information on the content of the AT privilege execution right corresponding to the special gamer with bonus is stored in the RAM 203 (step S213). When the setting value is changed, the contents of the execution right stored in the RAM 203 of the sub-control board 20 are cleared by the second initialization unit 640 when the setting is changed.

  If the content of the AT privilege execution right is not stored in the RAM 203 (step S213: NO), the effect control means 600 resets the AT privilege execution right information corresponding to the established special gamer with bonus in the RAM 203. (Step S214). Here, the information on the right to execute the AT privilege specifically includes the number of AT sets, the number of AT games in one set, the AT continuation rate, and the like as described above.

  Then, the game shifts to the corresponding special game state by the establishment of the special game combination with a privilege (step S215). Further, following this special gaming state, AT is executed under the condition of the execution right set by the AT execution means 620 described later (step S216).

  As another embodiment, when the special game combination with a bonus is established in step S212, the effect control unit 600 is configured to store information on the execution right of the AT privilege corresponding to the bonus in the RAM 203 ( Step S213: NO), the information changed to the execution right of the content different from the execution right of the privilege granted based on the winning by the winning lottery means 502 may be set in the RAM 203.

  For example, the effect control means 600 is a value smaller than the value set based on winning all or some of the parameters such as the AT set number variable 653, the AT game number counter 654, and the AT continuation rate setting value variable 655. Set to. In this case, a right that is more disadvantageous to the player than the AT execution right granted based on the winning is reset when the combination is established.

  As yet another embodiment, the effect control means 600 sets all or a part of parameters such as the AT set number variable 653, the AT game number counter 654, and the AT continuation rate setting value variable 655 based on winning. By setting a value larger than the value to be set, a right advantageous to the player may be reset when the winning combination is established.

(Direction lottery means)
The effect lottery means 610 provided in the sub-control board 200 shown in FIG. 8 is activated every time a command is received from the main control board 100, or when a specific rotation start command or role lottery result command is received, for example. Is done. The effect lottery means 610 includes a random number generator 209 and acquires a random value indicated by the random number generator 209 at a predetermined timing. The effect lottery means 610 refers to the effect lottery table stored in the ROM 202 and selects the effect content corresponding to the numerical range to which the acquired random number value belongs.

  In addition to the lottery (effect lottery) for selecting the effect pattern, the effect lottery means 610 may or may not notify the result of the lottery performed by the role lottery means 502 transmitted from the main control board 100. A lottery (a role announcement lottery) and a right to execute an AT effect that assists the player in an operation such as a stop operation order so that an internal winning combination is established, and a lottery (AT lottery) of the content of the execution right are also performed. .

(AT execution means)
The AT execution means 620 shown in FIG. 8 selects an effect pattern corresponding to the association between the combination indicated by the combination lottery result command and the stop operation order from among a plurality of effect patterns related to the AT. An effect pattern or AT effect image related to execution of AT may be selected by lottery by the effect lottery means 610.

  The AT execution means 620 receives a rotation stop command transmitted from the main control board 100 each time the stop buttons 56L, 56C, and 56R are stopped, and displays an AT effect image that notifies the reel to be stopped next. The images are sequentially displayed on the image display device 61. This notifies the player of a stop operation that ensures that the winning combination is won.

  The AT execution means 620 basically executes one set (for example, 30 games) of ATs by acquiring an AT execution right through AT lottery by the effect lottery means 610. The AT lottery is performed by the effect lottery means 610 during the AT state in which the AT is executed or at the end of one set of ATs. When the AT execution right is acquired, one set of ATs is continuously executed. The probability that the AT state will continue is called “AT continuation rate”.

  Further, in the slot machine 10 of the present embodiment, the right to execute the AT privilege is granted to the player based on the winning of the special gamer with a bonus such as the BB1 role or the BB2 role by the role lottery means 502. The contents of the AT execution right include those related to the end condition of the AT state such as the number of games of one set (for example, 30 games) and the AT continuation rate (for example, 30%).

  During the AT state, the AT state flag 652 of the RAM 203 of the sub control board 200 is set to ON. Further, the contents of the AT execution right given by the AT lottery or the winning of the BB1 role are stored in the RAM 203. For example, the set number of AT execution rights that are stocked is set in the AT set number variable 653, the number of games in one AT state to be executed is set in the AT game number counter 654, and the given AT continuation rate is set. The corresponding set value is set in the AT continuation rate set value variable 655.

  When the AT is executed by the AT execution means 620, for example, the player can surely win a medal by assisting the pushing order or the like for drawing a symbol corresponding to a specific small role into the active line. Further, for example, by assisting the above-described “bell” symbol to be drawn into a middle line where three active lines intersect, the medal payout can be increased. Furthermore, for example, the assist shown in FIG. 7 (a) for displaying a specific symbol of the re-gamer b to be transitioned to RT1 having a relatively high winning probability of the re-gamer, or conversely, the re-gamer's winning probability is relatively high. An advantageous state can be given to the player also by assisting not to display the specific symbol of the re-gamer c so as not to transition to a low RT0 and leading to an RT state where medals are not reduced.

According to the slot machine 10 of the embodiment of the present invention described above, the following advantageous effects can be obtained as compared with the related art.
(1) The effect control means 600 of the sub-control board 200 sets the execution right of the AT privilege corresponding to the special game combination with a bonus in the RAM 203 when the special game combination with a bonus such as the BB1 role or the BB2 role is established. With such a configuration, even if the set value is changed and the right to execute the AT privilege has been lost, the right to execute the AT is set at the same time as the special game player is established, so the execution of the AT is guaranteed. . Therefore, the player's profits / privileges can be maintained even after the setting is changed. In addition, even if the special game with benefits is won, or even if the RT2 state where the AT privilege should have been granted is restored after the setting change, the execution of the AT is guaranteed, so there is also a mismatch in the gaming state Absent.
(2) In addition, the effect control unit 600 changes the execution right to a content different from the execution right of the privilege granted based on the winning by the combination lottery unit 502 and resets it in the RAM 203. Thereby, the interest adjustment between the hall side and the player side can be performed in more detail.
