Description

  The present invention relates to a slot machine capable of generating a predetermined winning according to a display result of a variable display device capable of variably displaying a plurality of types of identification information each identifiable.

  A slot machine generally includes a variable display device having a plurality of (usually three) reels on which a plurality of types of symbols as identification information are drawn on the outer periphery, and first, a bet number is determined by a player's BET operation. The reels start to rotate when the start operation is performed with the set number of bets set, and the rotation is stopped by operating a stop button provided corresponding to each reel. When all reels stop rotating, a winning combination occurs when a predetermined winning symbol combination (for example, 7-7-7, hereinafter referred to as a symbol combination) is arranged on the winning line. To do. That is, the game is advanced by the player's operation.

  These winning combinations include special roles with a transition to a special gaming state that is advantageous to the player, small roles with the addition of gaming values such as medals, and replays that can be played without using gaming values. There is a re-playing role accompanied by a game. These winning combinations are generally those that allow the winning combination to be awarded on the condition that a winning lottery performed simultaneously with the start operation is won.

  In addition, in this type of slot machine, once a special role is won, it may be carried over until the selected special role is won, and the special role will not be won until certain conditions are met while the special role is carried over. It has been proposed to be able to intentionally change the winning frequency of a special role by controlling to (for example, see Patent Document 1).

JP 2003-180946 A

  In the slot machine described in Patent Document 1, after the special role is won, control is performed during the high probability replay period. During this period, when the replay role win probability is high and the replay role is won, The special role cannot be won by giving priority to the control associated with the re-gamer over the control to win the special role, but in the high-probability re-game period, even if the re-game player is elected, it is constant. In this case, it is not possible to win a special role, and it is not possible to win any of the roles. There was a problem of giving a feeling of loss to the person.

The derivation control means includes
A game value less than the game value required to set the predetermined number of bets out of the small prize winning and the fact that the first carryover special prize (BB (2)) is allowed to occur (one piece) ) Or when the occurrence of the second special carry-over prize (BB (3)) is determined when it is determined that the generation of the specified small role prize (1 (1) to (5)) is permitted. And the derivation operation means (stop switches 8L, 8C, 8R) when it is determined to allow the specified small role winning (one (1) to (5)). Regardless of the operation procedure, the control for deriving the display result of the specific small role winning (1 (1) to (5)) is performed.
When it is determined that both the occurrence of the first carry-over special prize (BB (2)) and the occurrence of the re-game prize (re-gamer) are determined, or the second carry-over special prize When it is determined that both the occurrence of a winning (BB (3)) and the occurrence of the re-game winning (re-gamer) are determined, the derivation operation means (stop switches 8L, 8C, 8R) control to always derive the display result of the re-game prize (re-game player) regardless of the operation procedure of
It has been determined that the first carryover special prize (BB (2)) is allowed to be generated, and the specific small role prize (1 (1) to (5)) is allowed to be generated or Perform control to be able to derive the display result of the first carryover special prize (BB (2)) on the condition that it is not determined to allow the occurrence of a re-game prize (re-gamer),

The slot machine is
The pre-determining means determines that the specific small role winning (1 (1) to (5)) is allowed to occur with a higher probability than the determination of not allowing any winning (losing). By doing so, the first carryover special prize (BB (2)) is obtained when the decision to allow the occurrence of the first carryover special prize (BB (2) winning flag) is carried over. When the probability that the display result can be derived and the determination to allow the occurrence of the second carryover special prize (winning flag of BB (3)) are carried over, the second carryover special prize (BB ( 3)) while limiting the probability that the display result can be derived,
When the decision to allow the occurrence of the second carryover special prize (winning flag of BB (3)) is carried over, the decision to allow the occurrence of the first special carryover prize (BB ( When the pre-determining means decides that the re-game winning (re-gamer) is allowed to occur with a higher probability than when the winning flag (2) is carried over, the first carry-over flag is determined. From the probability that the display result of the first carry-over special prize (BB (2)) can be derived when the decision to allow the occurrence of a special prize (winning flag of BB (2)) is carried over When the decision to allow the occurrence of the second carry-over special prize (winning flag of BB (3)) is carried over, the display result that becomes the second carry-over special prize (BB (3)) is It is characterized by limiting the probability that it can be derived. doing.
According to this feature, in the state where the decision to allow the occurrence of the first carry-over special prize or the decision to allow the occurrence of the second carry-over special prize is carried over, any occurrence of the prize is allowed. The decision to allow the occurrence of the specified small role winning with a higher probability than the decision to not, and the decision to allow the occurrence of the first carryover special prize or the occurrence of the second carryover special prize is permitted. In the state where the decision to do so is carried forward, when the occurrence of the specific small role winning is permitted, the display result that becomes the first carry-over special prize or the display result that becomes the second carry-over special prize is derived. However, the display result is always derived as a specific small role winning, and the decision to allow the occurrence of the first carry-over special winning or the decision to allow the second carrying-over special winning is carried over. Replay When winning is permitted, the display result for the first carry-over special prize or the display result for the second carry-over special prize is not derived, and the display result for the re-game prize is always derived. Therefore, even if the first carryover special prize or the second carryover special prize is allowed, it is determined that the specific small role prize is allowed or the replay prize is allowed. In the game, it becomes impossible to generate the first carryover special prize and the second carryover special prize, and even if the first carryover special prize and the second carryover special prize are allowed, the first carryover The probability of occurrence of a special prize or a second carryover special prize can be limited. Furthermore, while the decision to allow the occurrence of the first carry-over special prize or the decision to allow the occurrence of the second carry-over special prize is being carried over, it is also decided to allow the occurrence of a new special prize. Since there is no change in the probability that it is determined by the pre-determining means that the occurrence of the special prize is allowed, the period in which the special prize is low and the period in which the special prize is high are generated. Can be provided.
Also, it is more likely that the decision to allow the occurrence of the second carryover special prize is carried over than the decision to allow the occurrence of the first carryover special prize is carried over. Since it is determined that the re-game winning is allowed, the first carry-over special winning is allowed and the second carry-over special winning is generated even during a period when the probability of the special winning is low. It is possible to give a change to the probability that the permitted special winning will occur after the permitted case is permitted.
In addition, the decision to allow the occurrence of the first special carry-over special prize or the determination that the occurrence of the specific small role winning is permitted with a higher probability than the decision that the occurrence of any winning is not permitted or When the decision to allow the occurrence of the second carry-over special prize is carried over, the probability of the first carry-over special prize and the second carry-over special prize is limited, so the first carry-over special prize or Even if it is not possible to generate the second carryover special prize, it is possible to generate a special small role prize accompanied by the addition of gaming value, and the first carryover special prize and the second carryover special prize are generated. Even if the probability is limited, the feeling of loss given to the player can be reduced.
In addition, since the gaming value that is given even if the specific small role winning is generated is less than the gaming value used to set a predetermined number of bets necessary for starting the game, the first carryover If the decision to allow the occurrence of the special prize or the decision to allow the occurrence of the second carry-over special prize is carried over, the probability of occurrence of the first carry-over special prize and the second carry-over special prize is calculated. It is possible to consume the game value while generating the specific small role winning accompanied by the addition of the game value to limit.
Note that the predetermined number of bets is a bet number of at least 2 if one bet number is set for each unit of gaming value, and a bet number of 3 or more may be set. The game may be started by setting the maximum bet number. In addition, if the number of bets is set to one for a plurality of units of gaming value, the number of bets is at least one, and two or more bets are set or the maximum bet is set. Thus, the game may be started. Further, the game may be started by setting a bet amount determined according to a plurality of game states.
The special prize may be only the first carryover special prize and the second carryover special prize, or the first carryover special prize, the second carryover special prize, and the first carryover special prize. And a special prize different from the second carryover special prize may be included.
In addition, when it is determined that both the occurrence of the first carry-over special prize or the acceptance of the second carry-over special prize and the occurrence of the re-game prize are determined. The first carry-over special prize is allowed to be generated when the decision to allow the first carry-over special prize or the decision to allow the second carry-over special prize has not been carried over A decision to allow the occurrence of the first carry-over special prize, or when the decision to allow the occurrence of the second carry-over special prize and the occurrence of the re-game prize are determined at the same time, or This includes both when the decision to allow the occurrence of the second carry-over special prize is carried over and when the decision to allow the occurrence of the re-game prize is decided alone.
In addition, when it is determined that both the occurrence of the first carry-over special prize or the second special carry-over special prize is permitted and the specific small part prize is permitted. The generation of the first carry-over special prize is determined when the decision to allow the first carry-over special prize or the decision to allow the second carry-over special prize is not carried over. When it is simultaneously determined to allow or to allow the occurrence of the second special carry-over prize and to allow the occurrence of the specific small part prize, the fact that the first carry-over special prize is permitted This includes both when the determination or the decision to allow the second carry-over special prize is allowed to be carried out independently when the decision to allow the specific small part prize is made.
In addition, the control that enables the display result of the first carryover special prize or the second carryover special prize to be derived is the first carryover special prize or the second regardless of the operation procedure of the derivation operation means. The display result of the carry-over special prize may be always derived, or the first carry-over special prize or the second prize only when operated in a specific operation procedure among a plurality of operation procedures. The display result for the special carry-over special prize is always derived, and if it is operated by a procedure other than a specific operation procedure, the display result for the first special carry-over prize or the second special carry-over prize is not derived. Control may also be used. In this case, the plurality of operation procedures may be a plurality of predetermined operation timings. When the variable display device includes a plurality of variable display areas, a display result is derived to each variable display area. An operation for designating the order to be performed may be used, or an operation procedure in which both the operation timing and the derivation order are combined may be used.

The slot machine according to means 2 of the present invention is the slot machine according to means 1,
If the decision to allow the occurrence of the second carry-over special prize (BB (3) winning flag) is carried over, the decision to allow the occurrence of the second special carry-over prize (BB) The probability that the pre-determining means independently determines that the special prize (special role) is allowed to be generated in a state where the winning flag (3) has not been carried forward is the re-game prize (re-game character). It is characterized by the fact that it is replaced with the probability of making a decision to allow the occurrence of.
According to this feature, when the decision to allow the occurrence of the second carry-over special prize is carried over, the probability that the occurrence of the special prize is permitted alone before the carry-over is re-established. Since it replaces the probability of making a decision to allow the occurrence of game winnings, if the decision to allow the occurrence of the second carryover special winning is carried over, the decision to newly allow the occurrence of special winnings Even if it is no longer performed independently, the probability that no other prizes will be allowed other than the second carry-over special prize, that is, the increase in the probability that the second carry-over special prize will occur is surely limited, and the special prize is awarded. It is possible to clearly show the difference in the probability that a special prize will occur between a period during which the probability of occurrence of a special prize is low and a period during which a special prize is likely to occur.

The slot machine according to means 3 of the present invention is the slot machine according to means 1 or 2,
The derivation control means includes a special special prize (BB (1)) different from the first carry-over special prize (BB (2)) and the second carry-over special prize (BB (3)) among the special prizes. Is determined to be permitted, and the specific small role winning (1 (1) to (5)) is determined to be permitted, the specific small winning (1 (1)) To (5)), the display result of the specific special prize (BB (1)) is controlled to be derived with priority over the display result of (5)).
According to this feature, when it is determined to allow the occurrence of a specific special prize and to allow the occurrence of a specific small prize, it is determined that the specific special prize is more than the display result of the specific small prize. Since the display result is preferentially derived, if the occurrence of the special special prize is permitted, the special special prize can be generated with a high probability, and the second carryover special prize is allowed to occur. It is possible to provide a period with a higher probability that a special prize will occur than when the decision is carried over.
Note that the control for deriving the display result of the specific special prize prior to the display result of the special small prize winning means that the display of the specific special prize is obtained when both display results can be derived. This is control for deriving the result, and does not preclude control for deriving the display result for the specific small role winning when only the display result for the specific small role winning can be derived. Further, only the control for deriving the display result for the specific special prize may be performed.

Re-game prize (re-play game) with the grant of the re-game (replay game) that allows the game to be performed without using the game value without the occurrence of the second carryover special prize (BB (3)) When both of the determination to allow the occurrence of a (game player) are determined, the re-game winning (re-game player) is displayed regardless of the operation procedure of the derivation operation means (stop switches 8L, 8C, 8R) Control to ensure that the results are derived,
The slot machine decides to allow the occurrence of the first carryover special prize (BB (2) winning flag) and decides to allow the occurrence of the second carryover special prize (BB (3)) When the pre-determining means determines that the second carry-over special prize (BB (3)) is allowed to be generated when the winning flag is not carried over, (1) to (5)), or simultaneously determining whether to allow the occurrence of the re-game prize (re-gamer), the second carry-over special prize (BB ( 3)) is not possible to derive the display result.
According to this feature, the second carry-over special prize is generated when the decision to allow the first carry-over special prize and the decision to allow the second carry-over special prize are not carried over. In a game in which the second carry-over special prize cannot be generated in a game that is allowed, and it is always carried over after the next game, the probability that a special prize will surely occur if the second carry-over special prize is allowed Can be shifted to a low period of time.
Note that the predetermined small role winning may be the specific small role winning, or may be a different type of small winnings different from the specific small role winning. Furthermore, the predetermined small role winning may include both the specific small role winning and other types of small winnings.

The hopper motor 34b is connected, and these electric components are driven based on control of a main control unit 41 (described later) mounted on the game control board 40.

  The game control board 40 includes a microcomputer having a main CPU 41a, ROM 41b, RAM 41c, and I / O port 41d. The main control unit 41 controls the game, and random numbers in a predetermined range (0 to 65535 in this embodiment). A random number circuit 42 for generating a signal, a pulse oscillator 43 for supplying a clock signal of a constant frequency to the random number circuit 42, and a detection signal input from a switch connected directly to the game control board 40 or via the power supply board 101.

  The main CPU 41a has an interrupt function (including an interrupt prohibition function) such as a timekeeping function and a timer interrupt, executes a program (described later) stored in the ROM 41b, and performs processing related to the progress of the game. Each part of the control circuit mounted on the game control board 40 is controlled directly or indirectly. The ROM 41b stores fixed data such as programs executed by the main CPU 41a and various tables. The RAM 41c is used as a work area when the main CPU 41a executes a program. The I / O port 41d inputs / outputs a control signal to / from each circuit connected via a signal input / output terminal included in the main control unit 41.

  The main control unit 41 includes a signal input terminal, and detection states of various switches connected to the game control board 40 are input to the input port via these signal input terminals. The input state of these signal input terminals is monitored by the main CPU 41a, and the main CPU 41a executes basic processing that shifts in stages according to the input state of the signal input terminals, that is, the detection states of various switches.

  Further, the main CPU 41a has an interrupt function as described above, and can execute an interrupt process by interrupting the basic process when an interrupt occurs. In this embodiment, four types of interrupts of interrupts 1 to 4 can be executed. For each interrupt, the counter mode (externally depending on the signal input from the trigger terminal provided separately from the signal input terminal) An interrupt mode for generating an interrupt) and a timer mode (an interrupt mode for generating an internal interrupt according to the number of clock inputs of the main CPU 41a) can be selected and set.

  In the present embodiment, among the interrupts 1 to 4, interrupt 2 is set to the counter mode, interrupt 3 is set to the timer mode, and interrupts 1 and 4 are unused. The trigger terminal is connected to the power interruption detection circuit 48 described above, and the main CPU 41a generates an interrupt 2 in response to the input of the voltage drop signal output from the power interruption detection circuit 48, and the power interruption interruption described later. Execute the process (main). Further, the main CPU 41a generates an interrupt 3 every time the number of clock inputs reaches a certain number, that is, every certain time interval (about 0.56 ms in this embodiment), and a timer interruption process (main) described later. Execute. Moreover, although the interrupts 1 and 4 are set to unused, the interrupts 1 and 4 may generate | occur | produce by noise etc. For this reason, when the interrupts 1 and 4 occur, the main CPU 41a executes an unused interrupt process that immediately returns to the original process.

  The main CPU 41a is set to prohibit other interrupts during execution of interrupt processing based on the occurrence of any one of interrupts 1 to 4, and a plurality of interrupts are generated simultaneously. In this case, interrupts that are executed with priority in the order of interrupts 2, 3, 1, 4 are set. In other words, when interrupt 2 and other interrupts occur simultaneously, interrupt 2 is prioritized and when interrupt 3 and interrupt 1 or 4 occur simultaneously, interrupt 3 is prioritized. To run.

  Further, the main CPU 41a temporarily stores the data in use stored in the register in a later-described stack area provided in the RAM 41c at the start of the interrupt process based on the occurrence of any of the interrupts 1 to 4. And the data saved in the stack area at the end of the interrupt process is returned to the register.

  Further, the main control unit 41 is supplied with backup power even during a power failure, and the data stored in the RAM 41c is held while the backup power is being supplied.

  The main CPU 41a repeatedly loops the process according to the control state until the detection state of the various switches connected to the game control board 40 is changed as a basic process, and step by step according to the change of the detection state of the various switches. Execute the process to move to. Further, the main CPU 41a has an interrupt function as described above, and can interrupt the basic process by the occurrence of the interrupt and execute the interrupt process. The voltage output from the power interruption detection circuit 48 The power interruption interrupt process (main) is executed in response to the input of the decrease signal, and the timer interrupt process (main) is executed at regular time intervals (about 0.56 ms in this embodiment). In addition, the execution interval of the timer interrupt process (main) is set to a time longer than the sum of the time required to complete the repeated process according to the control state in the basic process and the execution time of the timer interrupt process (main) Therefore, the process that is repeated according to the control state between the current and next timer interrupt processes (main) is completed at least once.

  The main CPU 41a transmits various commands to the effect control board 90 via the I / O port 41d. A command transmitted from the game control board 40 to the effect control board 90 is sent in only one direction, and no command is sent from the effect control board 90 to the game control board 40. The transmission line of the command transmitted from the game control board 40 to the effect control board 90 is composed of a strobe (INT) signal line, a data transmission line, and a ground line, and is connected via the effect relay board 80. The game control board 40 and the effect control board 90 are not directly connected.

  The effect control board 90 is connected to effect devices such as a liquid crystal display 51 (see FIG. 1), an effect LED 52, speakers 53 and 54, and the reel LED 55 described above, which are arranged on the front door 1b of the slot machine 1. These effect devices are driven based on control by a later-described sub-control unit 91 mounted on the effect control board 90.

  In this embodiment, the sub-control unit 91 mounted on the effect control board 90 controls the output of the effect devices such as the liquid crystal display 51, effect effect LED 52, speakers 53 and 54, and reel LED 55. However, in addition to the sub-control unit 91, an output control unit that directly controls the output of the effect device is mounted on the effect control board 90 or another board, and the sub-control unit 91 is based on a command from the main control unit 41. The output control unit may determine the output pattern of the effect device, and the output control unit may control the output of the effect device based on the output pattern determined by the sub control unit 91. In such a configuration, the sub control unit 91 and the output control may be performed. The output control of the rendering device is performed by both of the units.

  Further, in the present embodiment, the liquid crystal display 51, the effect effect LED 52, the speakers 53 and 54, and the reel LED 55 are exemplified as the effect device, but the effect device is not limited to these, for example, a mechanically driven display. A device or a mechanically driven item may be applied as the effect device.

  Similar to the main control unit 41, the effect control board 90 includes a sub CPU 91a, ROM 91b, RAM 91c, and a microcomputer provided with an I / O port 91d. The sub control unit 91 controls the effect, and the effect control board 90. A display control circuit 92 that performs display control of the liquid crystal display 51 connected to the LED, an LED effect circuit 52 that performs drive control of the effect LED 52 and the reel LED 55, an audio output circuit 94 that controls audio output from the speakers 53 and 54, Supplied to a reset circuit 95 that gives a reset signal to the sub CPU 91a when the power is turned on or when an initialization command from the sub CPU 91a is not inputted for a certain period of time, a clock device 97 that outputs time information including date information and time information, and a slot machine 1 The power supply voltage is monitored, and when a voltage drop is detected, this is indicated The power interruption detection circuit 98 that outputs a pressure drop signal to the sub CPU 91a, other circuits, and the like are mounted. The sub CPU 91a receives a command transmitted from the game control board 40 and performs an effect. While performing various controls, each part of the control circuit mounted on the effect control board 90 is controlled directly or indirectly.

  Similar to the main CPU 41a, the sub CPU 91a has an interrupt function (including an interrupt prohibition function). One of the interrupt terminals of the sub control unit 91 is connected to a strobe (INT) signal line that is output when the main control unit 41 transmits a command, among the command transmission lines, and the sub CPU 91a receives the strobe signal. An interrupt is generated based on the input to acquire a command from the main control unit 41 and execute a command reception interrupt process to be stored in the buffer. Further, the sub CPU 91a executes an interrupt process (sub) to be described later by generating an interrupt every time the number of clock inputs reaches a certain number, that is, every certain interval. One of the interrupt terminals of the sub-control unit 91 is connected to the power interruption detection circuit 98, and the sub CPU 91a responds to the input of the voltage drop signal output from the power interruption detection circuit 98. Execute processing (sub). Further, when an unused interrupt occurs in the sub CPU 91a, an unused interrupt process for immediately returning to the original process is executed.

  Also, unlike the main CPU 41a, the sub CPU 91a interrupts the process even when the timer interrupt process (sub) is being executed when an interrupt is generated based on the input of the strobe signal (INT). The command reception interrupt process is executed at the same time, and the command reception interrupt process is executed with the highest priority even if interrupts that trigger the timer interrupt process (sub) occur at the same time. Note that command reception interrupt processing is also prohibited during the execution of power interruption interrupt processing (sub), but if an interrupt that triggers power interruption interrupt processing (sub) occurs at the same time, command reception Prioritize interrupt processing.

  The sub-control unit 91 is also supplied with backup power at the time of a power failure, and the data stored in the RAM 91c is held while the backup power is supplied.

  In the slot machine 1 of the present embodiment, the medal payout rate changes according to the set value. Specifically, the medal payout rate is changed by using a winning probability corresponding to a set value in an internal lottery described later. The set value is composed of 6 levels of 1 to 6, with 6 being the highest payout rate and the payout rate being lower as the value is decreased in the order of 5, 4, 3, 2, 1. That is, when 6 is set as the set value, the advantage is highest for the player, and as the value decreases in order of 5, 4, 3, 2, 1, the advantage decreases stepwise.

  In order to change the setting value, it is necessary to turn on the power of the slot machine 1 after the setting key switch 37 is turned on. When the setting key switch 37 is turned on and the power is turned on, the setting value read from the RAM 41c is displayed on the setting value display 24 as a display value, and the setting value can be changed by operating the reset / setting switch 38. Transition to the setting change state. When the reset / setting switch 38 is operated in the setting change state, the display value displayed on the setting value display 24 is updated one by one (when further operation is performed from the setting 6, the display returns to the setting 1). . When the start switch 7 is operated, the display value is determined as the set value. Then, when the setting key switch 37 is turned OFF, the determined display value (setting value) is stored in the RAM 41c of the main control unit 41, and the state shifts to a state in which the game can proceed.

  In order to confirm the set value, after the game is over, the setting key switch 37 may be turned on with no bet amount set. When the setting key switch 37 is turned on in such a situation, the setting value read out from the RAM 41c is displayed on the setting value display 24, thereby shifting to a setting confirmation state in which the setting value can be confirmed. In the setting confirmation state, the game cannot be progressed, and by turning the setting key switch 37 to the OFF state, the setting confirmation state is ended and the state in which the game can proceed is returned.

  In the slot machine 1 of the present embodiment, when the main CPU 41a detects a voltage drop signal from the power interruption detection circuit 48, a power interruption interrupt process (main) is executed. In the power interruption interrupt processing (main), the register is saved in a stack of a RAM 41c, which will be described later, and data for destructive diagnosis (in this embodiment, 5AH) in which any bit becomes 1, that is, a specific value other than 0 In addition to storing data, the RAM parity adjustment data is calculated so that the RAM parity based on the data stored in all areas of the RAM 41c is 0, and the RAM 41c is stored. The RAM parity is a value calculated as an exclusive OR of values stored in each bit of the corresponding area (all areas in this embodiment) of the RAM 41c. Therefore, if the RAM parity based on the data stored in all areas of the RAM 41c is 0, the RAM parity adjustment data is 0, and the RAM parity based on the data stored in all areas of the RAM 41c is 1. In this case, the RAM parity adjustment data is 1.

  The main CPU 41a calculates the RAM parity based on the data stored in all areas of the RAM 41c at the time of activation, confirms the value of the destructive diagnosis data, the RAM parity is 0, and the destructive diagnosis The processing state of the main CPU 41a is restored to the state before the power interruption based on the data stored in the RAM 41c on the condition that the value of the data for use is correct, but the RAM parity is not 0 (in the case of 1) or is destroyed. If the value of the diagnostic data is not correct, it is determined that the RAM is abnormal, and the RAM abnormal error code is set in the register to control the RAM abnormal error state so that the progress of the game is disabled. Unlike the other error states, the RAM abnormal error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, and a new set value is set in the setting change state described above. It will not be released until

  In this embodiment, all the data stored in the RAM 41c is held by the backup power source even in the event of a power failure, and when the main CPU 41a determines that the data in the RAM 41c is normal when the power is turned on. Although the configuration is such that the control state before power interruption is restored based on the data stored in the RAM 41c, only the data necessary for the restoration of the control state in the event of a power failure is backed up among the data stored in the RAM 41c. It may be configured to return to the control state before power interruption based on the backed up data.

  In addition, when returning to the control state before the power interruption when the power is turned on, it is not necessary to return all the control states to the control state before the power interruption, and the minimum control state that does not disadvantage the player For example, it is not necessary to restore the state of all input ports to the state before power interruption.

  In addition, when the sub CPU 91a detects the voltage drop signal from the power interruption detection circuit 98, the sub CPU 91a also executes a power interruption interrupt process (sub). In the power interruption interrupt processing (sub), the register is saved in a stack of a RAM 91c described later, and destructive diagnosis data in which any bit is 1 is stored in the RAM 91c, and data stored in all areas of the RAM 91c. The RAM parity adjustment data is calculated so that the RAM parity based on 0 becomes 0 and stored in the RAM 91c.

  Then, the sub CPU 91a calculates the RAM parity based on the data stored in all areas of the RAM 91c at the time of activation, and based on the data stored in the RAM 91c on the condition that the RAM parity is 0. The processing state of the sub CPU 91a is restored to the state before the power interruption. If the RAM parity is not 0 (1), it is determined that the RAM is abnormal and the RAM 91c is initialized. In this case, unlike the main CPU 41a, the performance is not disabled only by initializing the RAM 91c.

  In this embodiment, all data stored in the RAM 91c is held by the backup power source even during a power failure, and the sub CPU 91a determines that the data in the RAM 91c is normal when the power is turned on. Although the configuration is such that the control state before power interruption is restored based on the data stored in the RAM 91c, only the data necessary for restoration of the control state is backed up in the event of a power failure out of the data stored in the RAM 91c. It may be configured to return to the control state before power interruption based on the backed up data.

  In addition, when returning to the control state before the power interruption when the power is turned on, it is not necessary to return all the control states to the control state before the power interruption, and the minimum control state that does not disadvantage the player It is not necessary to restore the state of the input port or the progress in the middle of the production when it is interrupted. For example, while backing up only data indicating the gaming state such as whether it is in the BB or the normal gaming state, other than the effect corresponding to the gaming state (the effect during the BB during the BB, the normal effect when in the normal gaming state) If a power outage occurs during the execution of a specific production (such as a small role announcement), it will be backed up when the power is turned on instead of resuming the specific production that was being performed at the next power-on. An effect corresponding to the gaming state being played may be executed from the beginning.

  Next, initialization of the RAM 41c of the main control unit 41 will be described. The storage area of the RAM 41c of the main control unit 41 is divided into an important work, a general work, a special work, a set value work, a non-saved work, an unused area, and a stack area.

  The important work is a work in which data that is inconvenient to be initialized at the end of the BB, such as various display devices and LED display data, input / output data of the I / O port 41d, and a game time clock counter, is stored. The general work is a work that stores data that can be initialized at the end of the BB, such as a stop control table, a stop symbol, the number of medals paid out, and the total number of medals paid out in the BB. The special work stores data that is not initialized even before the setting is changed, such as data for transmitting a command to the effect control board 90 and various software random numbers (a random number for determination value addition described later, a random number for changing an initial value). Work. The set value work is a work that stores a set value used when a lottery is performed in the internal lottery process. The unsaved work is a work that holds the state of various switches, and a value is always set regardless of whether or not the data in the RAM 41c is destroyed at the time of activation. The unused area is an unused area in the storage area of the RAM 41c, and is initialized if any one of a plurality of initialization conditions described later is satisfied. The stack area is an area in which data saved from the register of the main CPU 41a is stored, and the unused stack area is established by any one of a plurality of initialization conditions to be described later, like the unused area. In this case, the used stack area is not initialized because the program continues.

  In this embodiment, the main CPU 41a destroys the data in the RAM 41c when a RAM error occurs, when the setting key switch 37 is activated with the setting key switch 37 turned on, when the BB is completed, and when the setting key switch 37 is activated with the setting key switch 37 turned off. Otherwise, when the five initialization conditions at the end of one game are satisfied, five types of initializations with different areas initialized according to each initialization condition are performed.

  Initialization 0 is initialization that is performed when a RAM abnormality error occurs. In initialization 0, all the areas (including the unused area and the unused stack area) of the storage area of the RAM 41c except the used stack area are stored. It is initialized. Initialization 1 is an initialization that is performed before the setting key switch 37 is turned on at the time of startup and shifts to the setting change state. In the initialization 1, a special area in the storage area of the RAM 41c is selected. Areas other than the work, the unsaved work, and the used stack area (including the unused area and the unused stack area) are initialized. Initialization 2 is initialization performed at the end of the BB. In initialization 2, the general work, the unused area, and the unused stack area are initialized in the storage area of the RAM 41c. Initialization 3 is initialization that is performed when the setting key switch 37 is in an OFF state at the time of startup and the data in the RAM 41c is not destroyed. The used stack area is initialized. Initialization 4 is initialization performed at the end of one game. In initialization 4, an unused area and an unused stack area in the storage area of the RAM 41c are initialized.

  In this embodiment, initialization 1 is performed before the change of the setting change state. However, the initialization 1 is performed at the end of the setting change state, or both before the change of the setting change state and at the end of the setting change state. Also good. In this case, if the set value work is initialized, the determined set value is lost. Therefore, the initialization of the set value work is not performed in the initialization at the end of the setting change state.

  In the slot machine 1 according to the present embodiment, the prescribed number of bets that can be set according to the gaming state is determined as described above, and the prescribed number of bets that are determined according to the gaming state is set. It becomes possible to start the game on the condition. In this embodiment, as will be described later, there are a regular bonus (hereinafter referred to as RB) (big bonus (hereinafter referred to as BB)) and a normal gaming state as a gaming state. 1 is defined as the specified number of bets, and in RT (0) to (2), 3 is defined as the specified number of bets. For this reason, if the gaming state is RB (BB), the game can be started when 1 is set as the bet number, and 3 is set as the bet number if RT (0) to (2). Then, the game can be started. In this embodiment, the winning line L is activated when a specified number of bets corresponding to the gaming state is set, and 1 is set as the bet number in RB (BB). The winning line L is activated at the time point, and the winning line L is activated when 3 is set as the betting number in RT (0) to (2).

  The slot machine 1 according to the present embodiment plays a role on an activated pay line (hereinafter, the activated pay line is simply referred to as a pay line) when all the reels 2L, 2C, 2R are stopped. A winning combination will be awarded when all the combinations of symbols are called. The combination may be a combination of the same symbols or a combination including different symbols. The type of winning combination is determined according to the game state, but it can be roughly divided into a small role with payout of medals and a replay that can start the next game without the need to set the number of bets. There are a game combination and a special combination with a transition of the game state. Below, a small role and a re-playing role are collectively called a general role. In order for winning of each combination determined according to the gaming state to occur, it is necessary to win an internal lottery to be described later and set a winning flag of the combination in the RAM 41c.

  Of the winning flags for each of these combinations, the winning flag for the small role and the re-playing role is valid only in the game in which the flag is set, and is invalid in the next game. It is valid until a combination of combinations permitted by the flag is completed, and is invalid in a game having a combination of combinations permitted. In other words, once the special combination winning flag is won, even if the combination of the combination permitted by the flag cannot be made, the winning flag is not invalidated and is carried over to the next game. It becomes.

  As the role in the slot machine 1, as shown in FIG. 5, as a special role, a big bonus (1), a big bonus (2), a big bonus (3) (hereinafter referred to as a big bonus (1) is BB (1), Big Bonus (2) is BB (2) and Big Bonus (3) is BB (3)) as a small role (1), 1 (2), 1 (3), 1 ( 4) Replay (1) and replay (2) are defined as replaying roles for 1 (5) and 10 (1).

  One (1) wins when the combination of “black grapes-black 7-black 7” is aligned on the winning line in any gaming state, and one (2) wins in any gaming state. A winning combination occurs when the combination of “Black Watermelon-Black 7-Black 7” is complete on the line. One (3) is a combination of “White Watermelon-Black 7-Black 7” on the winning line in any gaming state. Winners will be awarded when all of the games are aligned, and one (4) will be awarded when the combination of “black orange-black 7-black 7” is aligned on the winning line in any gaming state. In any game state, the winning line is awarded when the combination of “white orange-black 7-black 7” is aligned. When any one of (1) to (5) wins, one medal is paid out in RT (0) to (2), and 15 medals are paid out in RB (BB). The 10 cards are awarded when the combination of “bell-bell-bell” is aligned on the winning line in any gaming state, and 10 medals are paid out at RT (0) to (2). In BB), 15 medals are paid out.

  Replay (1) is awarded when the combination of “Replay-Replay-Replay” is aligned on the winning line in RT (0) to (2), and Replay (2) is awarded in RT (0) to (2). When a combination of “black 7-black 7-bell” is arranged on the winning line, the winning is made. When Replay (1) or Replay (2) wins, there is no payout of medals, but the next game can be started without setting the number of bets again, so it corresponds to the number of bets that do not need to be set in the next game This is essentially the same as paying out three medals.

  BB (1) is awarded when the combination of “Black 7-Black 7-Black 7” is aligned on the winning line at RT (0) (1), and BB (2) is RT (0) (1). The winning line is awarded when the combination of “Black 7-Black 7-White 7” is aligned on the winning line, and BB (3) becomes “Black 7-Black 7-Replay” on the winning line at RT (0) (2). The winning combination will be awarded when the combination is complete.

  In this embodiment, as will be described later, in RT (0), BB (2) and BB (3) are always won at the same time as a small role or a re-playing role, and in that case, a small role or a re- Since a game player wins, a combination of “black 7-black 7-white 7” that becomes BB (2) in RT (0) and “black 7-black 7-replay” that becomes BB (3) The combination will never be on the winning line.

  When any of BB (1) to (3) wins, the gaming state shifts to BB and simultaneously shifts to RB. RB is a gaming state that is advantageous to the player over other gaming states by increasing the winning probability of a small role and increasing the number of payouts at the time of winning a prize. After RB started, 4 games were digested Or when winning 8 games (any kind of combination is acceptable), whichever comes first. When the RB is finished, if the BB is not finished, the process proceeds to the RB again, and the RB is repeatedly controlled until the BB is finished. That is, during BB, it is always controlled to RB. The BB triggered by the winning of BB (1) ends when the total number of medals paid out to the player in the BB exceeds 60, and the BB triggered by the winning of BB (2) When the total number of medals paid out to the player during the BB exceeds 90, the BB triggered by winning the BB (3) has the total number of medals paid out to the player during the BB. It ends when it exceeds 300 sheets. At the end of the BB, the RB is also ended regardless of whether or not the RB end condition is satisfied.

  Hereinafter, the internal lottery of the present embodiment will be described. In the internal lottery, it is determined whether or not the above winning combination is permitted before the display results of all the reels 2L, 2C, and 2R are derived and displayed (actually, when the start switch 7 is detected). To do. In the internal lottery, first, a random number for internal lottery (an integer from 0 to 65535) is acquired. Then, for each combination determined according to the gaming state and whether or not the special combination is carried over, the acquired random number for internal lottery and the number of judgment values for each combination determined according to the gaming state, the number of bets and the set value Is done according to.

  In the present embodiment, as shown in FIG. 6, whether the gaming state is RT (0) (not carrying over the special role) or RT (1) (2) (while carrying the special role), Depending on whether it is RB (BB), the combination that is the subject of the internal lottery differs.

  If the gaming state is RT (0) (not carrying a special role), 1 GR (1 (1) +1 (2) +1 (3) +1 (4) +1 (5)), BB (1) +1 sheet GR, BB (2) +1 sheet GR, BB (3) +1 sheet GR, 10 sheets, Replay (1), BB (1) + Replay (2), BB (2) + Replay (2 ), BB (1) are sequentially read out as the target combination of the internal lottery.

  If the gaming state is RT (1) or RT (2) (while the special combination is being carried over), one GR, ten, replay (1), and replay (2) are sequentially read out as the target combinations for internal lottery.

  When the gaming state is RB (BB), 1 sheet GR and 10 sheets are sequentially read out as a target combination for internal lottery.

  In the internal lottery, the number of determination values determined corresponding to the role to be subject to the internal lottery, the current gaming state and the set value are sequentially added to the random number for the internal lottery, and when the result of addition overflows, It is determined that the winning combination has been won. For this reason, a winning combination will be won with a probability (number of determination values / 65536) according to the number of determination values.

  If a winning combination of any combination is determined, a winning flag corresponding to the combination determined to be winning is set in the internal winning flag storing work assigned to the RAM 41c. The internal winning flag storage work consists of a storage area of 2 bytes, of which the upper byte is assigned as the special role storing work for which the special role winning flag is set, and the lower byte is the winning of the general role It is assigned as a general role storage work for which a flag is set. Specifically, when a special combination is won, a special combination winning flag indicating that the special combination is won is set in the special combination storing work, and the winning flag set in the general combination storing work is cleared. When a general combination is won, a winning flag for the general combination indicating that the general combination is won is set in the general combination storing work. If no winning combination is selected, only the general winning combination work is cleared.

  Next, stop control of the reels 2L, 2C, 2R will be described.

  The main CPU 41a refers to the table index and the table creation data stored in the ROM 41b when the rotation of the reel starts and when the reel stops and the reel that is still rotating still remains. Create a stop control table for each reel. When any of the stop switches 8L, 8C, and 8R corresponding to the rotating reel is effectively detected, the stop control table of the corresponding reel is referred to and the slip of the referred stop control table is referred to. Based on the number of frames, control is performed to stop the rotation of the reels 2L, 2C, 2R corresponding to the operated stop switches 8L, 8C, 8R.

  In the table index, an index that indicates the start address of the area in which the data for table creation is stored, from the reference address when referring to the table index, according to the setting state of the winning flag by internal lottery (hereinafter referred to as the internal winning state) Differences up to the address where the data is stored are registered. As a result, a difference corresponding to the internal winning state is acquired, and the corresponding index data can be acquired by adding the difference to the reference address. Even when the winning combinations are different, when the same control is applied, the same address is stored as the index data. In such a case, the same table creation data is referred to. Thus, a stop control table is created.

  The table creation data includes a stop control table indicating the number of sliding frames according to the stop operation position, and an address of the stop control table to be referred to according to the reel stop status.

  The stop control table referred to according to the reel stop status is whether all reels are rotating, only the left reel is stopped, only the middle reel is stopped, only the right reel is stopped, It may vary depending on whether the middle reel is stopped, the left and right reels are stopped, the middle and right reels are stopped, and if any reel is stopped, stop Since there may be differences depending on the stop position of the reels already completed, the address of the stop control table to be referenced for each situation is registered for each rotating reel, and based on the top address of the table creation data, It is possible to specify the address of the stop control table that should be referred to according to the status of each, and it is necessary according to each status from this specified address. And to be able to identify the stop control table. Even when the reel stop status and the stopped position of the stopped reel are different, when the same stop control table is applied, the same address may be registered as the address of the stop control table. In such a case, the same stop control table is referred to.

  The stop control table is data that can specify the number of sliding frames for each timing when the stop operation is performed. In this embodiment, stepping motors that make one turn at a cycle of 168 steps (0 to 167) are used for the reel motors 32L, 32C, and 32R. That is, when the reel motors 32L, 32C, and 32R are driven for 168 steps, the reels 2L, 2C, and 2R make one round. Then, 21 areas (frames) divided every 16 steps (the number of steps that one symbol moves) are defined for one reel, and these areas are areas 0 to 20 from the reel reference position. A number is assigned. On the other hand, the number of symbols arranged on one reel is 21, and symbol numbers 0 to 20 from the reel reference position are assigned to symbols on each reel, so symbols 0 to 20 are assigned to each reel. , Area numbers 0 to 20 are assigned in order. In the stop control table, the number of sliding symbols for each area number is compressed and stored according to a predetermined rule, and the number of sliding symbols for each area number can be acquired by expanding the stop control table. Yes.

  As described above, the stop control table created by referring to the table index and the table creation data corresponds to the area number, and the area corresponding to each area number is the stop reference position (in this embodiment, the perspective window 3). Sliding frame when an operation of the stop switches 8L, 8C, 8R is detected at a timing (a timing in which the number of steps from the reel reference position is included in the range of the number of steps of each region number). It is a table with each number set.

  Next, the procedure for creating the stop control table will be described. First, at the start of reel rotation, the top address of the table creation data corresponding to the internal winning state of the game is acquired. Specifically, the table index is first referred to, index data corresponding to the internal winning state is obtained, table creation data is identified based on the obtained index data, and all reels are identified from the identified table creation data. The address of the stop control table for each reel corresponding to the state of rotation is acquired, and the stop control table for each reel stored at the acquired address is expanded to generate a stop control table for all reels.

  Further, when any one reel stops or any two reels stop, the index data acquired at the start of reel rotation, that is, the top address of the table creation data corresponding to the internal winning state of the game The table creation data is identified based on the table creation data, and the stop control table address of the unreacted reel corresponding to the stopped reel and the area number of the stop position of the reel is obtained from the identified table creation data. The stop control table for each stored reel is expanded to create a stop control table for the unstopped reels.

  Next, when the main CPU 41a effectively detects any one of the stop switches 8L, 8C, and 8R corresponding to the rotating reel, the control when the display result is derived to the corresponding reel will be described. When one of the stop switches 8L, 8C, and 8R corresponding to the rotating reel is effectively detected, the stop operation position area is determined based on the number of steps from the reel reference position when the stop operation is detected. The number is specified, the stop control table of the reel where the stop operation is detected is referred, and the number of sliding symbols corresponding to the area number of the specified stop operation position is acquired. Then, control is performed to rotate and stop the reel by the number of acquired sliding frames. Specifically, from the number of steps from the reel reference position at the time when the stop operation is detected, the number of steps from the acquired number of sliding frames to the stop is calculated, and the reel is rotated and stopped by the calculated number of steps. Take control. As a result, the area corresponding to the area number that is the stop position ahead of the number of sliding frames from the area corresponding to the area number of the stop operation position where the stop operation is detected is the stop reference position (in this embodiment, the perspective window 3 It will stop in the lower symbol area).

  In the table index of this embodiment, only one address is stored as index data corresponding to one internal winning state in one gaming state, and further, one table creation data includes one reel. Only one address is stored as the address of the storage area of the stop control table corresponding to the stop status (and the stop position of the stopped reel). In other words, table creation data corresponding to one internal winning state in one gaming state and stop control tables corresponding to reel stop states (and stopped positions of stopped reels) are uniquely determined. The stop control table created with reference to is unique for one internal winning state in one gaming state and the reel stop status (and the stop position of the stopped reel). Therefore, when all of the gaming state, the internal winning state, and the reel stop status (and the stop position of the stopped reel) are the same, the reel is based on the same stop control table, that is, the same control pattern. The stop control is performed.

  Further, in this embodiment, a value of 0 to 4 is determined as the number of sliding frames, and it is possible to stop the reel by pulling in a maximum of 4 frames after detecting the stop operation. In other words, the stop position of the symbol can be designated from a range of a maximum of 5 frames including the stop operation position where the stop operation is detected. In addition, since it is necessary to move one frame to move the reel for one symbol, it is possible to stop the reel by pulling in a maximum of four symbols after detecting the stop operation. The symbol stop position can be designated from a range of up to five symbols including the operation position.

  In this embodiment, when any of the winning combinations is won, the winning combination is drawn to the maximum in the range of 4 frames on the winning line, and the non-winning winning combination is drawn so that it is not aligned on the winning line. A stop control table with a defined number of frames is created and reel stop control is performed. If no winning combination is selected, a stop control table with a determined number of sliding symbols that do not have any combination And stop control of the reel. As a result, when a stop operation is performed, if the winning combination can be stopped on the winning line in the drawing range of up to 4 frames, the control is performed so that the winning combination is stopped. The combination that has not been performed will be controlled to be stopped in a drawing range of a maximum of 4 frames.

  When BB (1) is carried over from before the previous game and a small role is elected, or when BB (1) and a small role are elected at the same time when a special role is not carried over, BB (1) and If the small role is elected at the same time, the number of sliding symbols is determined so that the winning BB (1) is drawn to the winning line within the range of 4 frames, and the winning BB (1) is For stop operation positions that cannot be drawn into the winning line within the range of up to 4 frames, a stop control table in which the number of sliding frames is determined so that the selected small role is drawn into the winning line within the range of 4 frames is created. The reel stop control is performed. As a result, when the BB (1) that has been selected in the drawing range of a maximum of 4 frames can be aligned and stopped on the winning line when the stop operation is performed, control is performed to align and stop them. If the BB (1) that has been elected with a maximum of 4 frames on the winning line cannot be withdrawn, the special role that has been elected with a maximum of 4 frames on the winning line will be stopped. If it is possible, control is performed to align and stop, and a winning combination that has not been won is controlled to be stopped within the drawing range of 4 frames. That is, in such a case, the control for aligning BB (1) on the winning line is prioritized over the small combination, and the small combination can be awarded only when BB (1) cannot be drawn. In the present embodiment, the BB (1) configuration symbol is arranged within 5 symbols, that is, within an interval of 4 frames for each of the reels 2L, 2C, and 2R, and is necessarily arbitrary within the 4-frame pull-in range. It can be stopped at the position. For this reason, when BB (1) and a small role are simultaneously elected, BB (1) must be won together regardless of the operation timing of the stop switches 8L, 8C, 8R by the player. Become. That is, in such a case, control for aligning BB (1) on the winning line is prioritized over the small role, and BB (1) always wins.

  BB (2) or BB (3) and a small role are simultaneously played when a small role is won while BB (2) or BB (3) has been carried over from before the previous game or when a special role is not carried over If BB (2) or BB (3) and a small role are simultaneously elected, such as when winning, the number of sliding frames will be adjusted so that the selected small role is drawn to the winning line within a maximum of 4 frames. As for the stop operation position where the selected small role cannot be drawn into the winning line within a maximum of 4 frames, the BB (2) or BB (3) selected as the winning line is limited to a maximum of 4 frames. A stop control table in which the number of sliding frames is determined so as to be pulled in as much as possible is created, and reel stop control is performed. As a result, when a stop operation is performed, if it is possible to stop all the small roles that have been selected in the drawing range of up to 4 frames on the winning line and stop them, control is performed so that the winning combination is stopped. If you cannot draw a small role that has been won in the drawing range of up to 4 frames on the line, align BB (2) or BB (3) that has been won in the drawing range of up to 4 frames on the winning line. If they can be stopped, control is performed to align them and stop, and a winning combination that has not been won will be controlled to be stopped within the pull-in range of 4 frames. That is, in such a case, the control for aligning the small role on the winning line is prioritized over BB (2) or BB (3), and only when the small role cannot be drawn, BB (2) or BB (3 ) Can be awarded. In the present embodiment, one of the small roles (1) to (5) is always selected at the same time, and the configuration symbols of these one (1) to (5) are for any of the reels 2L, 2C, and 2R. Are arranged within 5 symbols, that is, within an interval of 4 frames, and can always be stopped at an arbitrary position within the drawing range of 4 frames. In addition, the 10 symbols are arranged within 5 symbols, that is, at intervals of 4 frames for each of the reels 2L, 2C, and 2R, and can always be stopped at an arbitrary position within the drawing range of 4 frames. it can. For this reason, when BB (2) or BB (3) and a small combination are simultaneously won, regardless of the timing of the operation of the stop switches 8L, 8C, and 8R by the player, the small combinations are always aligned and won. Will be. That is, in such a case, the control for aligning the small combinations on the winning line is prioritized over BB (2) or BB (3), and the small combination always wins.

  The special role and re-playing role are selected when the re-playing role is elected while the special role has been carried over from before the previous game, or when the special role and re-playing role are won at the same time without the special role being carried over. In the case of winning at the same time, when a stop operation is performed, control is performed so that the symbols of the re-gamer are aligned and stopped on the winning line within a drawing range of a maximum of 4 frames. In this case, the symbols constituting the re-playing combination are arranged within 5 symbols for each of the reels 2L, 2C, and 2R, that is, with an interval of 4 frames or less. Therefore, if a special combination and a replaying player are elected at the same time, the replaying game will always be awarded regardless of the operation timing of the stop switches 8L, 8C and 8R by the player. Will be. That is, in such a case, the control for aligning the re-games on the winning line has priority over the special game, and the re-games will always win.

  In this embodiment, after the rotation of the reels 2L, 2C, and 2R is started, the main CPU 41a continues to rotate the reels for which the stop operation has not been detected until the operation of the stop switches 8L, 8C, and 8R is detected. On the condition that the operation of the stop switches 8L, 8C, 8R is detected, control is performed to stop the display result on the corresponding reel. Even if the reel rotation temporarily stops due to the occurrence of a reel rotation error, the stop operation is still detected until the operation of the stop switches 8L, 8C, and 8R is detected after the reel rotation is restarted. Control is performed to stop the display result of the corresponding reels on the condition that the rotation of the reels that have not been continued is continued and the operation of the stop switches 8L, 8C, and 8R is detected.

  In this embodiment, control is performed to stop the display result on the corresponding reel on condition that the operation of the stop switches 8L, 8C, and 8R is detected. However, the rotation of the reel is started. When a predetermined automatic stop time has elapsed, even if the reel stop operation is not performed, it is assumed that the stop operation has been performed, and automatic stop control is performed to automatically stop each reel. May be. In this case, since the reels are stopped without the player's operation, it is preferable to derive a display result that does not constitute any combination even if any combination is won.

  Next, commands that the main CPU 41a transmits to the effect control board 90 will be described.

  In the present embodiment, the main CPU 41a sends a BET command, a credit command, an internal winning command, a reel rotation start command, a reel stop command, a winning determination command, a payout start command, a payout end command, a game state command to the effect control board 90. A plurality of types of commands including a standby command, an abort command, an error command, a return command, a setting start command, a confirmation start command, a confirmation end command, and an operation detection command.

  These commands are composed of 1-byte type data indicating the type of command and 1-byte extension data indicating the content of the command, and the sub CPU 91a can determine the type of command from the type data.

  The BET command is a command that can specify the number of inserted medals, that is, the number of medals used to set the bet number, and is a state from the end of the game (after setting change) to the start of the game. Sent when a medal is inserted or the bet number is set by operating the single BET switch 5 or the MAXBET switch 6 in a state where is not set. Further, since the BET command is transmitted when the betting number setting operation is performed, it is possible to specify that the betting number setting operation has been performed by receiving the BET command.

  The credit command is a command that can specify the number of medals stored as credits, and is a state from the end of the game (after setting change) to the start of the game, and in a state where a predetermined number of bets is set, Sent when a medal is inserted and credits are added.

  The internal winning command is a command that can specify the winning status of the internal winning flag and the type of the internal winning flag established, and is transmitted when the start switch 7 is operated to start the game. Further, since the internal winning command is transmitted when the start switch 7 is operated, it is possible to specify that the start switch 7 has been operated by receiving the internal winning command.

  The reel rotation start command is a command for notifying the start of reel rotation, and is transmitted when rotation of the reels 2L, 2C, and 2R is started.

  The reel stop command is a command that can specify whether the reel to be stopped is the left reel, the middle reel, or the right reel, the area number of the corresponding reel stop operation position, and the area number of the corresponding reel stop position. And is transmitted each time stop control is performed in accordance with the stop operation of each reel. Since the reel stop command is transmitted when the stop switches 8L, 8C, and 8R are operated, it is possible to specify that the stop switches 8L, 8C, and 8R are operated by receiving the reel stop command. .

  The winning determination command is a command that can specify the presence / absence of winning, the type of winning, and the number of medals to be paid out at the time of winning, and is transmitted after all the reels are stopped and the winning determination is performed.

  The payout start command is a command for notifying the start of payout of medals, and is transmitted when the payout of medals is started by paying out a prize or credit (including medals used for setting the number of bets). The payout end command is a command for notifying the end of payout of medals, and is transmitted when the payout of medals by winning and winning a credit is completed.

  The game state command is a command that can specify the game state of the next game, and is transmitted when the setting change state ends and when the game ends.

  The standby command is a command indicating a transition to the standby state, and after one game is over, a credit (which was used for setting the bet number) is set when the transition to the standby state is made after a predetermined time without setting the bet number. (Including medals) is sent out after the medal payout is completed and the payout end command is sent.

  The stop command is a command indicating the occurrence or release of the stop state, and after the end of the BB, the stop command indicating the occurrence of the stop state is transmitted when the ending effect waiting time has elapsed, and the reset operation is performed. When the stop state is released, a stop command indicating the release of the stop state is transmitted.

  An error command is a command that indicates the occurrence or cancellation of an error condition and the type of error condition. When an error is determined and controlled to an error condition, an error command indicating the occurrence and type of the error condition is sent and reset. When the error state is canceled after the operation is performed, an error command indicating the cancellation of the error state is transmitted.

  The return command is a command indicating that the main CPU 41a has returned to the control state before power interruption, and is transmitted when the main CPU 41a returns to the control state before power interruption.

  The setting start command is a command indicating the start of the setting change state, and is transmitted when shifting to the setting change state. Further, since the control state of the main CPU 41a is initialized with the transition to the setting change state, it is possible to specify that the control state of the main CPU 41a has been initialized by the setting start command.

  The confirmation start command is a command indicating the start of the setting confirmation state, and is transmitted when shifting to the setting confirmation state. The confirmation end command is a command indicating the end of the setting confirmation state, and is transmitted when the setting confirmation state ends.

  The operation detection command is a command indicating the detection state (ON / OFF) of the operation switches (one-sheet BET switch 5, MAXBET switch 6, start switch 7, stop switches 8L, 8C, 8R), and is transmitted at regular intervals. Is done.

  Among these commands, a setting start command, an error command indicating a RAM abnormality, and a return command are generated at a stage before an interrupt is permitted in the startup process and stored in a specific command transmission buffer assigned to a special work in the RAM 41c. And sent immediately.

  Commands other than a setting start command, an error command indicating a RAM abnormality, a return command, and an operation detection command are generated according to the progress of the game in the game process, and are temporarily stored in a normal command transmission buffer provided in a special work in the RAM 41c. Stored and transmitted in the command transmission process executed during the timer interrupt process (main).

  The operation detection command is generated every time the command transmission process is executed five times, stored in the aforementioned specific command transmission buffer, and immediately transmitted. In addition, when the operation detection command transmission time is reached with the unsent command stored in the normal command transmission buffer, priority is given to the transmission of the operation detection command and the normal command transmission buffer stores it. The untransmitted command is transmitted in the next command transmission process, and a plurality of commands are not transmitted in one command transmission process.

  Next, the control of the effect performed by the sub control unit 91 based on a command transmitted from the main CPU 41a to the effect control board 90 will be described.

  The sub CPU 91a executes a command reception interrupt process when a strobe signal indicating the transmission of a command from the main CPU 41a is input. In the command reception interrupt process, the command acquired from the command transmission line is stored in the reception buffer provided in the RAM 91c.

  In the timer interrupt process (sub), the sub CPU 91a determines whether or not an unprocessed command is stored in the reception buffer. If an unprocessed command is stored, the sub CPU 91a is the earliest stage. Based on the received command, the control pattern table stored in the ROM 91b is referred to. Based on the control contents registered in the control pattern table, various effects such as the liquid crystal display 51, the effect LED 52, the speakers 53 and 54, the reel LED 55, etc. Control the output of the device.

  In the control pattern table, the display pattern of the liquid crystal display 51 corresponding to the type of command, the lighting mode of the lighting effect LED 52, the output mode of the speakers 53 and 54, the lighting mode of the reel LED, etc. The control patterns of these effect devices are registered, and when the sub CPU 91a receives the command, the sub CPU 91a, among the control patterns registered corresponding to the effect patterns set in the RAM 91c in the game of the control pattern table, With reference to the control pattern corresponding to the type of command received, output control of the rendering device is performed based on the control pattern. Thereby, the production according to the production pattern and the progress of the game is executed.

  If the sub CPU 91a receives a new command during execution of an effect triggered by the reception of a certain command, the sub CPU 91a stops the effect based on the control pattern being executed, and responds to the newly received command. An effect based on the control pattern is executed. In other words, even if the production is not finished to the end, when a new command is received, the production that was being executed is canceled and a new command is canceled unless the received new command is not a command that triggers a new production. An effect based on the command is executed.

  In particular, in this embodiment, when an operation for setting the number of bets is made during the execution of an effect, that is, when the sub CPU 91a receives a BET command indicating that the number of bets has been set, the effect being executed is canceled. It is supposed to be. For this reason, if the player wants to proceed to the next game rather than seeing the production to the end, the production is canceled and the next game can be started. There is no. Further, when a credit or bet amount adjustment operation is performed during the performance, that is, after the sub CPU 91a receives a game state command indicating the end of the game, and before receiving an internal winning command indicating the start of the game. When the payout start command is received, the performance being executed is stopped. Credits and bets are settled when the game is terminated. In such a case, by terminating the performance that is being executed, there is an intention to end the game, but the performance continues unnecessarily. It is designed not to be overwhelmed.

  When the internal winning command is received, the effect pattern is selected at a selection rate corresponding to the result of the internal lottery indicated by the internal winning command, and is set in the RAM 91c. The selection rate of the effect pattern is registered in the effect table stored in the ROM 91b. When the sub CPU 91a receives the internal winning command, it is registered in the effect table according to the result of the internal lottery indicated by the internal winning command. Is selected from a plurality of types of effect patterns according to the selection rate, and the selected effect pattern is set in the RAM 91c as the effect pattern of the game, Even if the same command is received, a different control pattern is selected depending on the effect pattern selected when the internal winning command is received. As a result, different effects may be performed depending on the effect pattern.

  In the present embodiment, as shown in FIG. 7A, in RT (0) where none of the winning flags of BB (1) to (3) is carried over, 1 sheet GR, BB (1) +1 sheet GR , BB (2) +1 sheet GR, BB (3) +1 sheet GR, 10 sheets, Replay (1), BB (1) + Replay (2), BB (2) + Replay (2), BB (1) Regardless of the set value, each winning probability is subject to internal lottery, and it is 48636/65536, 5000/65536, 100/65536, 450/65536, 800/65536, 9000/65536, 500/65536, 50/65536, The probability of losing no winning combination is 500/65536.

  As described above, when BB (1) and a small combination are won at the same time, BB (1) is derived with priority over the small combination, and the configuration symbol of BB (1) is within the pull-in range. In RT (0), when BB (1) +1 GR is won or BB (1) is won (shaded area in the figure) BB (1) wins in the game.

  On the other hand, when BB (1) and a re-game player are won at the same time, the re-game player is derived with priority over BB (1), and the re-game game's configuration pattern is at an interval within the pull-in range. Therefore, in RT (0), when BB (1) + Replay (2) among the above-mentioned lottery targets is won, Replay (2) is won in the game and BB ( The winning flag of 1) is carried over after the next game and shifts to RT (1).

  In addition, when BB (2) or BB (3) and a small role are elected at the same time, the small role is derived in preference to BB (2) and BB (3), and the composition pattern of the small role is Since it is arranged at intervals within the pull-in range, in RT (0), when BB (2) +1 sheet GR and BB (3) +1 sheet GR are elected among the above lottery eligible roles, One of the cards (1) to (5) won in the game, and the winning flags of BB (2) and BB (3) were carried over after the next game, and the winning flag of BB (2) was carried over In this case, the process proceeds to RT (1), and when the winning flag of BB (3) is carried over, the process proceeds to RT (2).

  In addition, when BB (2) and a re-game player are won at the same time, the re-game player is derived with priority over BB (2), and the configuration pattern of the re-game game is at an interval within the drawing-in range. Therefore, in RT (0), when BB (2) + Replay (2) is selected among the above-mentioned lottery targets, Replay (2) is won in the game, and BB ( The winning flag of 2) is carried over after the next game and shifts to RT (1).

  Thus, in RT (0) in which none of the winning flags of BB (1) to (3) is carried over, when BB (1) +1 sheets GR and BB (1) are won, BB (1) BB (1) + Replay (2), BB (2) + 1 GR, BB (3) + 1 GR, BB (2) + Replay (2) The winning flags of these winning BBs (1) to (3) are carried over after the next game.

  As shown in FIG. 7B, in RT (1) during BB (1) carryover, special roles are not subject to lottery, and one GR, ten, replay (1), and replay (2) Regardless of the set value, each winning probability is 54186/65536, 800/65536, 9100/65536, 550/65536 regardless of the set value, and the probability of losing no winning combination is 900/65536 is there. In RT (1) during BB (1) carryover, the winning probability of 1 sheet GR, 10 sheets, and replay (2) is the same probability as RT (0), but the winning probability of replay (1) is RT (0) ).

  When BB (1) and a small combination are won at the same time, BB (1) is derived with priority over the small combination, and when BB (1) and a replaying combination are won at the same time, BB (1) In the case of RT (1) during BB (1) carryover, if one of the above lottery eligible roles is won, 10 is won or lost. BB (1) will win, and if Replay (1) and Replay (2) are won, Replay (1) and Replay (2) will win and the winning flag of BB (1) will be carried over Will remain.

  As shown in FIG. 7 (c), RT (1) during carry-over of BB (2) is the same as RT (1) during carry-over of BB (1), and the special role is excluded from the lottery. GR, 10 sheets, replay (1), and replay (2) are subject to internal lottery, and the respective winning probabilities are the same as RT (1) during carry-over of BB (1), and regardless of the set value, 54186 / 65536, 800/65536, 9100/65536, 550/65536, and the probability of losing no winning combination is 900/65536. Also in RT (1) during BB (2) carryover, the winning probability of 1 GR, 10 sheets, and Replay (2) is the same probability as RT (0), and the winning probability of Replay (1) is RT (0) ).

  If BB (2) and a small combination or re-playing combination are won at the same time, the small combination or re-playing combination will be given priority over BB (2), so BB (2) carrying over carry-over RT (1 ), BB (2) wins only in the case of a loss, and if 1 GR, 10 Replay (1), and Replay (2) are won, 1 (1) to (5) One of the 10 cards, replay (1) or replay (5) wins, and the winning flag of BB (2) remains carried over.

  As shown in Fig. 7 (d), RT (2) during carry-over of BB (3) is the same as RT (1) during carry-over of BB (1) or BB (2). Not eligible, 1 GR, 10 cards, Replay (1), Replay (2) are the targets of internal lottery, and the winning probability of 1 GR, 10 cards, Replay (2) is 54186 regardless of the set value / 65536, 800/65536, 150/65536, and the winning probability of replay (1) differs depending on the set value, setting 1: 10250/65536, setting 2: 10220/65536, setting 3: 10200/65536, Setting 4: 10170/65536, setting 5: 10150/65536, setting 6: 10100/65536, and the probability of losing none of the winning combinations varies depending on the setting value. 150/65536, set 2: 180/65536, set 3: 200/65536, set 4: 230/65536, setting 5: 250/65536, setting 6: 300/65536. That is, in RT (2) during BB (3) carryover, the higher the set value, the lower the winning probability of replay (1), and the higher the probability of losing. In RT (2) during BB (3) carryover, the winning probability of 10 GRs is the same as that of RT (0), but the winning probability of replay (1) is RT (0), RT ( It becomes higher than 1). In addition, the winning probability of replay (2) is lower than that of RT (0) and RT (1), but the winning probability of the entire re-gamer is higher than RT (0) and RT (1), The probability of losing is lower than RT (1).

  If BB (3) and a small role or re-playing role are won at the same time, the small role or re-playing role is given priority over BB (3), so that BB (3) carrying over RT (2 ), BB (3) wins only in the case of a loss, and if 1 GR, 10 Replay (1), and Replay (2) are won, 1 (1) to (5) One of the 10 cards, Replay (1), Replay (5) wins, and the winning flag of BB (3) remains carried over.

  In RT (0) to (2), the winning probability of 1 sheet GR is the highest, and when 10 sheets, replay (1), and replay (2) are not won, 1 sheet ( Any one of 1) to (5) will win, but the medals to be paid out when one (1) to (5) wins is the number of medals used for the number of bets required to start the game (3 The medals payout rate in RT (0) to (2) is less than 1, and the medals decrease.

  In this embodiment, as shown in FIG. 8, when BB (1) or BB (1) +1 sheet GR is won in RT (0) where none of the winning flags of BB (1) to (3) is carried over. BB (1) wins in the game, and when BB ends, it returns to RT (0) again.

  If BB (1) + Replay (2) wins in RT (0) where none of the winning flags of BB (1) to (3) is carried over, Replay (2) wins and BB (1) wins The flag is carried over to RT (1).

  In RT (1) during BB (1) carryover, if the special role is excluded from the lottery and the re-game player is elected, the winning flag of BB (1) remains carried over, but the re-game player If is not won, BB (1) wins regardless of whether the small role is won or not, so BB (1) wins with a probability of about 1 / 1.2 and BB ends. Then, it returns to RT (0) again.

  If BB (2) +1 sheet GR or BB (2) + Replay (2) is won in RT (0) where none of the winning flags of BB (1) to (3) is carried over, 1 sheet (1) to Either (5) or Replay (2) wins, and the winning flag of BB (2) is carried over to shift to RT (1).

  In RT (1) during BB (2) carryover, if the special role is not subject to lottery and if a small role or re-playing role is won, the winning flag of BB (2) will remain carried over, Since BB (2) wins only in the case, BB (2) wins with a probability of about 1 / 72.8, and when BB ends, it returns to RT (0) again.

  If RT (0) where none of the winning flags of BB (1) to (3) is carried over, if BB (3) +1 GR is won, one of (1) to (5) will win, The winning flag of BB (3) is carried over and shifts to RT (2).

  In RT (2) during BB (3) carryover, if the special role is not subject to lottery and if a small role or re-playing role is won, the winning flag of BB (3) will remain carried over, BB (2) wins only in the case. The probability of losing varies depending on the set value, and BB (3) wins with a probability of about 1 / 2188.5 to 1 / 436.9, and when BB ends, it returns to RT (0) again.

  In RT (0) in which none of the winning flags of BB (1) to (3) is carried over, BB (1), BB (1) +1 sheet GR, BB (1) + replay (2), BB ( 2) Since RT (0) is maintained except for the case where +1 sheet GR, BB (2) + replay (2), BB (3) +1 sheet GR is won, in RT (0) Thereafter, the game state to be transferred differs according to the winning probability ratio of the combination.

  The combined probability of winning probability of BB (1), BB (1) +1 sheet GR is about 1 / 11.9, the winning probability of BB (1) + replay (2) is about 1/131, BB (2) +1 sheet The combined probability of winning probabilities for GR, BB (2) + Replay (2) is about 1 / 436.9, and the winning probability for BB (3) +1 GR is about 1 / 145.6, at RT (0) BB (1) wins in the game is about 83.3%, BB (1) is transferred to RT (1) is about 7.6%, BB (2) is carried over RT (1 ) Is about 2.3%, and BB (3) is being carried over to RT (2) while the ratio is about 6.8%.

  If RT (0) wins BB (1) (BB (1), BB (1) +1 sheet GR, BB (1) + Replay (2)), the game is mostly won, In this game, BB (1) wins and the special role returns to RT (0), which is the lottery target, but at RT (0), BB (2) (BB (2) +1 sheets GR, BB ( 2) + replay (2)) or BB (3) (BB (3) + 1 sheet GR) wins, the loss (BB (2) The winning BB (2) and BB (3) may be awarded until the winning is about 1 / 72.8 and the winning of BB (3) is about 1 / 2188.5 to 1 / 436.9). The state that cannot be drawn and cannot receive the special role drawing will be maintained.

  Therefore, in RT (0), a high probability state with a high BB winning probability is looped at a ratio of about 90.9%, and a low probability state with a low BB winning probability is shifted at a ratio of about 9.1%. In other words, the low probability state ends when BB wins.

  In addition, even if BB (2) is won at RT (0) or BB (3) is won, it will shift to a low probability state with a low BB winning probability, but when BB (2) is won. RT (1) and BB (3) that are transferred to the game are different in RT (2) that is transferred when the winning BB wins, and the probability that the winning BB will win is different. In RT (0), BB (2) The winner is more likely to win BB than when BB (3) wins.

  As described above, in the slot machine 1 according to the present embodiment, when BB (1) is won in RT (0) in which none of the winning flags of BB (1) to (3) is carried over, in most cases Even if BB (1) wins in the winning game and BB (1) does not win in the winning game, BB (1) wins with a high probability in the subsequent game. Or, when BB (3) is won, BB (2) or BB (3) is not won in the winning game and is carried over from the next game onward. In RT (1) or RT (2) where the winning flag of BB (2) or BB (3) is carried over, a small role or replaying role is won with a higher probability than a loss, and BB (2) Alternatively, when a small role or replaying role is won while carrying the winning flag of BB (3), the winning small role or replaying role is preferentially derived, and BB (2) or BB (3) is Even after winning, it is impossible to win BB (2) and BB (3) in the game where the small role or re-playing role is won, so BB (2) and BB (3) will be won. Even then, the probability that BB (2) and BB (3) will win can be limited. Furthermore, in RT (1) and RT (2) where the winning flag of BB (2) or BB (3) is carried over, BB (1) to (3) will not be newly won. Without changing the winning probabilities of BB (1) to (3), it is possible to provide a period with a low probability of winning a BB and a period with a high probability of winning a BB.

  In this embodiment, when BB (2) or BB (3) wins at RT (0), a small role or re-playing role derived with priority over BB (2) or BB (3) If a winning combination or re-playing player is selected at the same time as BB (2) or BB (3), the winning winning combination or re-playing player will always win regardless of the timing of the stop operation. BB (2) or BB (3) won at the same time will not win, and will always be carried over after the next game, and will shift to the low probability state of BB, so BB (2) at RT (0) When BB (3) is won, the BB winning probability can be surely shifted to a low state.

  In addition, when the winning flags of BB (2) and BB (3) are carried over, the replaying role is compared to RT (0) where none of the winning flags of BB (1) to (3) is carried over. That is, in order to shift to RT (1) or RT (2) where the winning probability of the role derived in preference to BB (2) and BB (3) is shifted to BB (2) and BB (3), BB The probability of winning a prize can be further reduced, and the difference in the probability of winning a BB between the high probability state and the low probability state can be more clearly obtained.

  In particular, when the winning flags of BB (2) and BB (3) are carried over to RT (1) and RT (2), BB (1) to (3) are excluded from the lottery, but RT (0 ), The probability of the loss due to the fact that the special winning combination is removed from the lottery object, that is, the probability of winning BB (2) and BB (3). The increase can be limited.

  Furthermore, in RT (2) having the lowest winning probability of BB, the winning probability of the re-playing role is higher than the probability that the special role is won alone in RT (0), so BB (2), BB (3 ) Is surely limited, and the difference in the BB winning probability between the BB high probability state and the low probability state with the lowest BB winning probability can be further widened. it can.

  In this embodiment, when BB (2) or BB (3) is won at the same time as a small role, the small role is derived with priority over BB (2) and BB (3), whereas BB When (1) and a small role are elected at the same time, BB (1) is prioritized over the small role, and BB (1) and the small role are simultaneously elected at RT (0). If BB (1) wins and BB (1) and Replay (2) win simultaneously, even if the winning flag of BB (1) is carried over to RT (1), Since the BB (1) will win when the winning combination is won, the period until winning after the BB (1) wins is shortened, and the BB wins in the high probability state and the low probability state of the BB. The difference in probability can be made clearer.

  In addition, the configuration symbol of BB (1) is arranged within the pull-in range in any reel, and a game in which BB (1) can win a prize (BB (1) single winning or BB (1) and small role In the simultaneous winning of BB (1) (including the small part winning while carrying over BB (1)), BB (1) always wins regardless of the reel stop order and the timing of the stop operation. After that, the period until winning is further shortened, and the difference in BB winning probability between the high probability state and the low probability state of the BB can be made clearer. In this embodiment, BB (1) always wins regardless of the reel stop order and stop operation timing in a game in which BB (1) can win, but a predetermined specific stop may be used. Even if the BB (1) always wins regardless of the timing of the stop operation on the condition that the stop operation is performed in order, if the stop order as the winning condition does not change, Similar effects can be obtained.

  In RT (0), BB (1) wins alone or BB (1) takes precedence over the ratio of winning simultaneously with replay (2), which has priority over BB (1). Since the ratio of winning simultaneously with the small role GR is high, the period until winning a prize after BB (1) is won is further shortened, and the difference in the winning probability of BB between the high probability state and the low probability state of BB You can make it clearer.

  In RT (0), the winning probability of BB (1) with a high winning probability is higher than the winning probabilities of BB (2) and BB (3) with a low winning probability, and once BB (1) to (3 ) (1) will then win again before BB (2) and BB (3) win and move to the low probability state, so the low probability Until it shifts to the state, it is possible to continuously win BB in a short time.

  In the present embodiment, in the state where the winning flag of BB (2) or BB (3) is carried over, one piece (1) to (5) accompanied by paying out medals with a higher probability than a lose that does not win any combination. ) (1) GR that allows winning of a prize is won, and winning of BB (2) or BB (3) becomes impossible, so it is possible to win BB (2) and BB (3) being carried forward Even if it is not possible, the small role is won and the medal is paid out, and even if it is impossible to win the BB while carrying over, the feeling of loss given to the player can be reduced.

  In addition, even if one (1) to (5) whose winning is allowed by one GR is awarded, the number of medals to be paid out is one, and it is necessary to set the number of bets necessary to start the game. Since the number of medals to be used is less than three (RT (0) to (2) is three), BB (2) and BB (3) are in a state where the winning flags of BB (2) and BB (3) are carried over. In order to make it impossible to win a prize, it is possible to consume medals while winning a small role accompanied by paying out medals, that is, to reduce the number of medals owned by the player. There will be no advantage.

  In addition, not only when the winning flags of BB (2) and BB (3) are carried over, but also when any of the winning flags of BB (1) to (3) is not carried over, any combination is won. Since one GR that accepts one (1) to (5) winning with a medal payout with a higher probability than the losing not won is won, BB (2 from the winning frequency of 1 (1) to (5) ) Or BB (3) winning flag can be made difficult to determine, so even if BB (2) or BB (3) wins at RT (0), RT (0) 0), that is, the player's expectation for the high probability state of BB can be maintained.

  In the present embodiment, while the winning flags of BB (2) and BB (3) are carried over, the condition that BB (2) and BB (3) can win a prize is established, but BB (2), If BB (3) cannot be won, BB (2) and BB (3) cannot be won until the game is lost again, and if the player's skill is low, Although the winning probability of BB will be extremely low, the configuration symbols of BB (2) and BB (3) are arranged within the pull-in range in any reel, and BB (2), BB In a game where (3) can win (BB (2), BB (3) winning flag carry-over), BB (2), BB ( 3) will win, so the winners of BB (2) and BB (3) While the flag is being carried over, despite the conditions that allow BB (2) and BB (3) to be awarded, the BB (2) and BB (3) cannot be awarded to the player. Can be prevented from becoming extremely disadvantageous. In the present embodiment, BB (2), (3) always wins regardless of the reel stop order and the stop operation timing in the game where BB (2), (3) can be won. Even if the BBs (2) and (3) always win, regardless of the timing of the stop operation, on the condition that the stop operation is performed in a specific predetermined stop order, the winning conditions are satisfied. If the stop order does not change, the same effect as described above can be obtained.

  In this embodiment, even if BB (2) is won at RT (0), even if BB (3) is won, the BB (2) will move to a low probability state with a low winning probability. In RT (1) and BB (3) that are transferred when winning, the winning probability of the re-gamer is different in RT (2) that is transferred when BB (3) is won, so that the winning BB will win The probability is different, and the winning probability of BB is higher when BB (2) is won at RT (0) than when BB (3) is won. For this reason, even in the low probability state of the same BB, the winning probability can be changed according to the type of the winning BB.

  In addition, after winning, BB (2) and BB (3) with low winning probability after winning are more medals that can be expected during BB than winning BB (1). Later, even if BB (2) and BB (3) are elected and shift to the low probability state of BB, it is possible to expect more medals, so that the player's motivation to continue the game can be increased. it can. In particular, BB (3), which has a lower probability of winning BB than BB (2), can be expected to win more medals than BB (2). Even so, the player's willingness to continue the game can be maintained.

  In RT (0), only BB (1) and BB (2) among BB (1) to (3) are won simultaneously with replay (2), and BB is more than the ratio of winning simultaneously with BB (2). The ratio of winning simultaneously with (1) is higher, and after BB ends, replay (2) wins, so the possibility of BB (1) winning in the next game increases, and the high probability state of BB continues You can increase your expectation of what to do.

  Also, even if BB (1) does not win after winning Replay (2), BB (2) BB winning probability than RT (1) carrying over, that is, BB (3) carrying RT (2) Since it is determined that the state is high, it is possible to enhance the expectation for shifting to the high probability state of BB.

  In the present embodiment, only the BB (1) and the BB (2) among the BB (1) to (3) at RT (0) are elected simultaneously with the replay (2), but the BB (1) Any one of-(3) may be configured to win simultaneously with replay (2). In this case, among BB (2) and BB (3), the ratio of winning simultaneously with BB (2) is increased. Therefore, even if BB (1) does not win after winning Replay (2), BB (2) RT (1) in carry-over, that is, BB (3) RT (2) in carry-over wins BB Since the possibility of a state with a high probability is increased, it is possible to increase a sense of expectation for shifting to a high probability state of BB.

  Also, since BB (2) RT (1) during carry-over has a higher probability of replay (2) than BB (3) carry-over RT (2), BB (2) has a higher probability of winning. Even if it is in a state, the possibility of staying at RT (1) carrying over BB (2) is increased by replay (2) winning, so the transition to the high probability state of BB will soon occur You can increase your expectation.

  Also, the left and middle reels of replay (2) have the same symbols as those of BB (1) to (3), and even if replay (2) is won, the right reel Until is stopped, the expectation that any of BB (1) to (3) wins can be increased.

  Further, the sub CPU 91a of the present embodiment executes a specific effect at RT (0) to (2). The specific performance has the highest execution probability at RT (0), and RT (1) has a higher execution probability than RT (1) and RT (2). For this reason, the possibility of staying in the high probability state of BB is high by executing the specific performance, and it is possible to increase the expectation for BB to win, and the stay in the high probability state is almost Even if it is denied, since the possibility of staying at RT (1) during carryover increases, it is possible to increase the expectation for shifting to the high probability state of BB in the near future.

  Further, the sub CPU 91a of the present embodiment, when a small role other than one (1) to (5) wins a small role winning effect (for example, output of a medal payout sound or the like) indicating that the small role has been won. The prize winning line with a combination of small roles is executed, but when one (1) to (5) wins, the small bonus winning effect is not executed, and the winning probability is the highest. Although it is high, it is possible to make the other small role winnings that increase the medals substantially stand out from the winnings of one (1) to (5) that substantially reduce the medals, and the production frequency is moderate. Can be kept at a certain frequency.

  Although the embodiments of the present invention have been described with reference to the drawings, the present invention is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. Needless to say.

  For example, in the above embodiment, when BB (1) and a small combination are simultaneously elected, BB (1) is given priority over the small combination, and BB (1) and small combination are obtained at RT (0). However, when BB (1) and a small role are simultaneously elected, a small role is given priority over BB (1) in the same way as BB (2) and BB (3). In this case, it is preferable that the probability that BB (1) wins alone is higher than the probability that BB (1) is won simultaneously with a small role in RT (0). Is more preferable to win alone. By doing in this way, even if it is the structure which derives | leads-out a small role preferentially over BB (1), the winning probability of BB (1) can be raised.

  In addition, when BB (1) is configured to have a higher probability of winning BB (1) alone than the probability of winning simultaneously with a small role, or BB (1) is configured to win all alone, RT In (0), the probability of BB (1) winning alone increases, and the probability of BB (2), BB (3) loses during carryover, that is, the winning probability of BB (2) or BB (3) increases. BB (2), BB (3) BB (2), BB (3) BB (1) By reducing the probability of BB (3) carryover, ) Wins and a clear difference can be made in the winning probability between BB (2) and BB (3) wins.

  In the above embodiment, at RT (0), BB (2) and BB (3) are always selected simultaneously with a small role or replaying role derived in preference to BB (2) and BB (3), When BB (2) and BB (3) are elected at RT (0), BB (2) and BB (3) will not win, and will always carry over, but BB (2) and BB (3 ) May be elected alone, and when BB (2) and BB (3) are won in RT (0), a part of them may be awarded.

  In the above embodiment, in RT (0), BB (2) is elected simultaneously with a small role or replaying role, and BB (3) is elected simultaneously with only a small role, but BB (2) is small. A configuration in which only one of the winning combination or the replaying player is elected simultaneously may be used, or a configuration in which BB (3) is simultaneously winning only with the replaying player, and BB (3) is simultaneously winning with the small role or the replaying player. It may be configured.

  In the above-described embodiment, at RT (0), BB (2) and BB (3) are simultaneously elected with a small combination or re-playing combination derived in preference to BB (2) and BB (3). When BB (2) and BB (3) are elected in RT (0), the winning of BB (2) and BB (3) is limited. For example, BB (2) and BB (3) The plurality of types of first BB and second BB having a low winning probability during carry-over as shown in FIG. 5 and the configuration symbol of the first BB and the configuration symbol of the second BB in at least one of the reels. The first BB and the second BB with a low probability of winning during carry-over by arranging the configuration symbols of the first BB and the configuration symbols of the second BB beyond the draw-in range with different symbols In such a configuration, the first in RT (0) may be used. Even if the BB or the second BB wins alone, the player cannot determine which BB has won, and there is no common operating procedure that allows both BBs to win. As a result, these BBs cannot be won with certainty. Therefore, when the first BB or the second BB is won at RT (0), the winnings of the first BB and the second BB can be restricted. In addition, if the operation procedure selected by the player satisfies the winning condition of the winning BB, it is possible to win the winning first BB or second BB in RT (0).

  In the above embodiment, when RT (0) and BB (2), BB (3) and a small combination are won simultaneously, the small combination always wins and BB (2) and BB (3) cannot win. When BB (2), BB (3) and a small role are simultaneously elected at RT (0), BB (2) and BB (3) win a prize when the operating procedure satisfies the winning conditions. A possible configuration may be used. In this case, it is preferable that the operation procedure satisfying the winning condition is different depending on the type of the winning combination simultaneously won with BB (2) and BB (3). With such a configuration, BB ( 2) When BB (3) wins, the winnings can be restricted.

  In the above-described embodiment, when the winning flags of BB (2) and BB (3) are carried over, the winning probability of the re-gamer is raised more than before the winning flags of BB (2) and BB (3) are carried over. As a result, the BB (2) and BB (3) lost flags after the winning flag carry-over, that is, the BB winning probability is limited to a low value, but as shown in FIG. 9, before the BB carry-over and after the BB carry-over You may make it the game player's winning probability not change.

  In this case, when BB (1) and the small role are simultaneously elected, BB (1) is given priority over the small role, and when BB (2) and the small role are simultaneously elected, BB ( In addition to deriving a small role in preference to 2), as shown in FIG. 9 (a), BB (1) and BB (2) must always be a small role (or replay) while the BB winning flag is not carried over. 9), the probability of losing during the carry-over of the winning flag of BB (2) as compared to the case of not carrying over the winning flag of BB, as shown in FIG. 9 (b). (The hatched portion in FIG. 9B), that is, the winning probability of BB (2) does not increase.

  In the above embodiment, when the winning flags of BB (1) and BB (2) are carried over, the configuration shifts to RT (1) having a higher probability of winning the re-gamer than RT (0). Only when the winning flag of BB (3) is carried over, it shifts to RT (2) where the winning probability of the re-gamer is higher than RT (0), and the winning flags of BB (1) and BB (2) are carried over In such a case, the winning combination probability of the re-gamer may not be changed.

  In the above embodiment, even if the winning flag of BB (1) is carried over or the winning flag of BB (2) is carried over, the winning probability of the re-gamer is shifted to the same RT (1). However, the winning probability of the re-gamer may be different between the case where the winning flag of BB (1) is carried over and the case where the winning flag of BB (2) is carried over.

  In the above embodiment, in RT (2), the winning probability of the re-gamer becomes higher than the probability that BB (1) wins alone in RT (0), and the loss is limited. As in 1), the winning probability of the re-gamer may be increased only for a portion of the probability that BB (1) will win alone, and the loss may be limited.

  In the above embodiment, two types of BB (2) and BB (3) are defined as BBs that shift to a low probability state with a low BB winning probability when winning at RT (0). Depending on the situation, the winning probability of the subsequent BB is different, but when winning at RT (0), three or more kinds of BBs are defined as BBs that shift to a low probability state with a low winning probability of BB. Depending on which type of BB has been won, the winning probabilities of subsequent BBs may be different. Moreover, it is good also as one type of BB which transfers to a low probability state with a low probability of winning a BB when winning at RT (0).

  In the above embodiment, the constituent symbols of BB (1) to (3) are arranged in the pull-in range in all reels, and in the game in which these BB (1) to (3) can win, the reel stop order A game in which a prize is always awarded regardless of the timing of the stop operation, but the symbols (1) to (3) are arranged beyond the draw-in range, and BB (1) to (3) can be awarded. Even so, a configuration may be adopted in which no winning is made when a stop operation is performed at a timing outside the pull-in range.

  In the above embodiment, when BB (1) among BB (1) to (3) is won, BB is won with a high probability, and when BB (2) and BB (3) are won, BB winning probability is low, but regardless of the type of BB, if you win simultaneously with a small role or re-playing role, you will be able to derive a small role or re-playing role and not carry over BB Among them, a part of BB is elected simultaneously with a small role or a re-playing part, and a part is elected alone, so that when elected alone, the elected BB can be won. In the case where a winning combination with a small combination or replaying combination is won simultaneously, the BB winning probability may be low.

  In such a configuration, it is possible to continuously win the BB in a short period of time by increasing the probability that the BB wins alone than the probability that the BB wins simultaneously with the small role or the replaying role. Further, in this case, when the BB and the small role or the re-playing role are simultaneously won and the BB is carried over, the winning of the re-playing role is increased, so that the loss, that is, the BB can be won. It is preferable to reduce the probability, and by doing so, the difference between the high probability state of BB and the low probability state of BB can be clarified.

  In the above embodiment, a slot machine for setting bets using medals and credits is used, but the present invention is not limited to this, and a slot machine for setting bets using game balls, It may be a full credit type slot machine that uses only credits to set the number of bets.

  Further, in addition to the medal insertion mechanism such as the flow path switching solenoid 30 and the insertion medal sensor 31, a ball take-in device that takes in a game ball, and a take-in ball that detects a game ball taken in by the ball take-in device In addition to a medal payout mechanism, such as a hopper motor 34b and a payout sensor 34c, a ball payout device for paying out game balls and a payout ball detection switch for detecting game balls payed out by the ball payout device It is possible to set a bet number using both medals and game balls and play a game, and the present invention may be applied to a slot machine in which medals and game balls are paid out by winning.
