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 is generated 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. In general, these winning combinations can be won on the condition that an internal lottery performed simultaneously with the start operation is won.

  In addition, this type of slot machine suggests the possibility of being controlled in a gaming state (for example, a bonus) advantageous to the player over a series of periods, and whether or not the gaming machine is finally controlled in an advantageous gaming state. There has been proposed a technique for executing a continuous effect to notify such a result (see, for example, Patent Document 1).

JP 2007-260163 A

  The slot machine described in Patent Document 1 is configured such that another continuous effect can be executed according to the result of the internal lottery during the continuous effect. There was a possibility that the player's sense of expectation could be diminished depending on the event that changed to another production.

  The present invention has been made paying attention to such problems, and reduces the player's expectation by changing the continuous production that suggests the possibility of being granted an advantageous right to another production. It is an object of the present invention to provide a slot machine that can prevent such a situation.

In order to solve the above-described problem, a slot machine according to claim 1 of the present invention provides:
A variable display unit capable of variably displaying a plurality of types of identification information each capable of being identified,
After displaying the variable display unit in a variable manner, the display result is derived by stopping the variable display of the variable display unit, and in a slot machine capable of generating a prize according to the display result,
A pre-determining means for deciding whether or not to allow the winning to occur before the display result is derived;
A right grant determining means for determining whether or not to grant a right to control to an advantageous state advantageous to the player;
When it is determined that the right granting determination means allows the occurrence of a specific prize that may grant a right, an effect suggesting the possibility that the right is granted for a continuous performance period exceeding one game. A continuous production execution means capable of executing a continuous production that leads to a production result of whether or not the right is finally granted;
When it is determined that the specific winning is allowed during the execution of the continuous production, it is possible to execute the interrupt production that suggests the possibility of the right being granted by terminating the continuous production. Interrupt production execution means;
With
The specific prize includes the first specific prize and the second specific prize that is more likely to be granted the right than the first specific prize,
The first specific winning is permitted when it is determined that the generation of the specific winning is permitted during execution of the continuous performance triggered by the determination that the second specific winning is permitted. During the execution of the continuous production triggered by the fact that the effect has been decided, the rate of execution of the interrupt production is lower than when it is decided to allow the occurrence of a specific prize,
During the execution of the continuous production triggered by the fact that the specific winning is permitted and the right is not granted, it is determined that the specific winning is permitted and the right is granted. In the case of the event, it is determined that the occurrence of the specific prize is permitted and the decision to allow the occurrence of the specific prize is made during the execution of the continuous performance triggered by the fact that the right is not granted. It is characterized by a higher percentage of interrupt effects being executed than when it is not decided to grant.

The slot machine of means 1 of the present invention is:
A variable display section (reels 2L, 2C, 2R) capable of variably displaying a plurality of types of identification information each identifiable,
In the slot machine (slot machine 1) in which the variable display unit is variably displayed, the display result is derived by stopping the variable display of the variable display unit, and a winning can be generated according to the display result.
Prior determination means (internal lottery) for determining whether or not to allow a winning to occur before the display result is derived,
A right grant determining means (internal lottery) for determining whether or not to grant a right (special role) for controlling to an advantageous state advantageous to the player;
When the predetermination unit determines that the right granting determination unit allows the generation of a specific prize (watermelon, cherry) that may grant the right (special role), it continues for more than one game. An effect that suggests the possibility that the right (special role) has been granted is performed over the effect period, and a continuous effect that ultimately leads to an effect result indicating whether the right (special role) has been granted is executed. Continuous production execution means capable of,
When it is determined by the pre-determining means that the specific winning (watermelon, cherry) is allowed during the execution of the continuous production, the right (special role) is granted by terminating the continuous production. Interrupt production execution means capable of newly executing an interruption production (continuous production) that suggests the possibility of
With
The specific prize includes a first specific prize (cherry) and a second specific prize (watermelon) that is more likely to be granted the right than the first specific prize,
The fact that the specific prize (watermelon, cherry) is allowed to be generated by the pre-determining means during the execution of the continuous production triggered by the fact that the second specific prize (watermelon) is decided to be allowed If it is determined, the pre-determining means (watermelon, cherry) of the specific prize is executed by the pre-determining means during the execution of the continuous production triggered by the fact that it is determined that the first specific prize (cherry) is permitted. It is characterized in that the rate at which the interruption effect (continuous effect) is executed is lower than when it is determined that the generation is allowed.
According to this feature, it is determined that it is determined that the second specific winning is likely to be given the right to control to an advantageous state more advantageous to the player than the first specific winning. During execution of continuous production triggered, even if it is decided to allow the generation of a specific prize, it is specified during execution of continuous production triggered by the decision to allow the first specific prize Since the rate at which the interruption effect is executed is lower than when it is determined that the winning is allowed, it is highly likely that the right to control to an advantageous state advantageous to the player is granted. By changing the suggested continuous production to another production in the middle, the player's expectation that the right to control to the advantageous advantageous state suggested by the continuous production was granted was reduced. To prevent It can be.
In the case where it is determined by the pre-determining means that the occurrence of the specific winning is permitted during the execution of the continuous production triggered by the fact that the second specific winning is permitted, The discount is more than when it is determined by the predetermining means that the occurrence of the specific prize is permitted during the execution of the continuous production triggered by the fact that the first specific prize is allowed. The ratio of execution of the combined effect is low means that the specific prize is generated by the pre-determining means during the execution of the continuous effect triggered by the determination that the second specific prize is allowed. When it is determined to allow, the interruption effect may not be executed.
Further, the first specific prize and the second specific prize may be different in the combination of symbols, or the same combination of symbols, but may be different only in the stop position.
In addition, the interruption effect may be an effect different from the continuous effect, or the same effect. When an effect different from the continuous effect is applied, the effect may be more than one game, or an effect that ends within one game. But it ’s okay.

The slot machine according to means 2 of the present invention is the slot machine according to means 1,
The continuous production includes a plurality of types of continuous production (production patterns 1 and 2) having different possibilities of being granted the right suggested by the continuous production,
The interrupt effect (continuous effect) includes a plurality of types of interrupt effects (effect patterns 1 and 2) with different possibilities of being given the right (special role) suggested by the interrupt effect,
The fact that the specific prize (watermelon, cherry) is allowed to be generated by the pre-determining means during the execution of the continuous production triggered by the fact that the second specific prize (watermelon) is decided to be allowed If determined, the type of interrupt effect (continuous effect based on effect pattern 2) is executed, which suggests that the right (special role) is more likely to be granted than the continuous effect being executed. The percentage to be played is not limited, and the type of interrupt production (based on production pattern 1) that suggests the possibility that the right (special role) suggested by the continuous production during execution is less than the possibility It is characterized in that only the rate at which (continuous production) is executed is limited.
According to this feature, the execution of a continuous production triggered by the decision to allow the second specific prize, which is likely to be given a right that is more advantageous to the player than the first specific prize. In the middle, there is no restriction on the rate at which the type of interrupt production of which it is suggested that there is a possibility that the right is granted more than the continuous production being executed, and it is suggested by the continuous production during the execution. Since the rate at which the type of interrupt production of the type that suggests the following possibility is executed is limited, there is a high possibility that the right advantageous to the player is granted It is limited to changes to the production that can suggest that the continuous production that is suggested is less likely to be given a right that is more advantageous to the player in the middle, and the player's expectation is Limit until further changes in production It never will be.
In the case where it is determined by the pre-determining means that the occurrence of the specific winning is permitted during the execution of the continuous production triggered by the fact that the second specific winning is permitted, The second specification specifies that only the rate at which an interrupt effect of a type implying the possibility that the right suggested by the continuous effect being executed is less than or equal to the possibility is executed is limited. When it is determined by the pre-determining means that the generation of the specific prize is permitted during the execution of the continuous production triggered by the fact that it is determined that the winning is permitted, There may be a case in which the kind of interruption effect in which the following possibility is implied is not executed.

The slot machine of means 3 of the present invention is the slot machine according to means 1 or 2,
The specific prize is less likely to be given the right (special role) than the second specific prize (watermelon) and has a third specific prize (cherry) equal to or higher than the first specific prize (cherry). )
The third specific prize (cherry) is allowed to be generated by the pre-determining means during the execution of the continuous effect triggered by the fact that the second specific prize (watermelon) is decided to be allowed. Than the case where the first specific prize (cherry) is decided, the third specific prize ( When it is determined that the occurrence of cherry) is permitted, the rate of execution of the interrupt effect (continuous effect) is higher.
According to this feature, the execution of a continuous production triggered by the decision to allow the second specific prize, which is likely to be given a right that is more advantageous to the player than the first specific prize. In the middle, the occurrence of the third specific prize that is unlikely to be given a more advantageous right is allowed, and the expectation is impaired by changing the continuous production to another production. While the situation can be reduced, there is a high possibility that a more advantageous right is given during the execution of the continuous production triggered by the decision to allow the first specific prize. Since the occurrence of the third specific prize is permitted and the possibility that the continuous production will be changed to another production becomes high, the player's expectation is due to the continuous production being changed to another production by the occurrence of the specific prize. Can effectively enhance
In the meantime, it has been determined by the pre-determining means that the generation of the third specific prize is allowed during the execution of the continuous production triggered by the fact that the second specific prize is allowed. It is determined that the pre-determining means is allowed to generate the third specific prize during execution of the continuous performance triggered by the fact that the first specific prize is permitted. In the case of being played, the pre-determined during the execution of the continuous effect is triggered by the fact that it is determined that the second specific winning is permitted. When it is determined by the means that the generation of the third specific prize is permitted, the interruption effect may not be executed.
In addition, the third specific prize may be a specific prize having a lower possibility of being granted the right than the second specific prize and more than the first specific prize. The same prize may be used.
Also, the first specific prize and the third specific prize, and the second specific prize and the third specific prize may be different in the combination of symbols, or the same combination of symbols, but only the stop position. It can be different.

The slot machine of means 4 of the present invention is the slot machine according to any one of means 1 to 3,
It has been determined that the interruption effect execution means allows the generation of a specific prize of the same type as the specific prize (watermelon, cherry) that triggered the start of the continuous effect during the execution of the continuous effect. As a condition, a special interrupt effect (continuous effect based on effect pattern 3) that is not executed in other situations is executed.
According to this feature, it is unlikely that it is determined that the generation of a specific prize of the same type as the specific prize that triggered the start of the continuous production during the execution of the continuous production is permitted. Only when a high event occurs, the player's satisfaction can be effectively enhanced by executing the special interruption effect.

The slot machine of means 5 of the present invention is the slot machine according to any one of means 1 to 4,
Allowing the occurrence of the specific prize (watermelon, cherry) by the pre-determining means during execution of the continuous production triggered by the decision to allow the second specific prize (watermelon) to occur When the effect is determined, when the right (special role) is granted at the start of the continuous performance, and when the right (special role) is not granted at the start of the continuous performance, The rate at which the interruption effect (continuous effect) is executed is different.
According to this feature, the execution of a continuous production triggered by the decision to allow the second specific prize, which is likely to be given a right that is more advantageous to the player than the first specific prize. When the occurrence of a specific winning is permitted, it can be estimated whether or not a right advantageous to the player has been granted from the beginning depending on whether or not an interrupt effect is executed.
In addition, when the right is granted at the start of the continuous effect, or when the right is not granted at the start of the continuous effect, the interrupt effect may not be executed in either case. .

There are five types of winning lines L4 set across the symbols arranged side by side, the winning line L4 set across the symbols, the lower row of the reel 2L, the middle row of the reel 2C, the upper row of the reel 2R, that is, the winning line L5 set across the symbols lined up to the right. It is defined as.

  When the start switch 7 is operated in a state where the game can be started, the reels 2L, 2C, and 2R rotate, and the symbols of the reels 2L, 2C, and 2R continuously vary. When any one of the stop switches 8L, 8C, 8R is operated in this state, the rotation of the corresponding reels 2L, 2C, 2R is stopped, and the display result is derived and displayed on the fluoroscopic window 3.

  Then, when all the reels 2L, 2C, 2R are stopped, one game is completed, and a combination of symbols (hereinafter also referred to as roles) that are activated and predetermined on the winning line is each reel 2L, 2C, 2R. When the display result is stopped, a winning occurs, and a predetermined number of medals are awarded to the player and added to the credit. Further, when the credit reaches the upper limit number (50 in this embodiment), medals are paid out directly from the medal payout opening 9 (see FIG. 2). In addition, when the combination of symbols with payout of medals is arranged on a plurality of winning lines that are activated, the total number of payouts determined for each combination of symbols that are activated and aligned on the winning line is totaled, The total number of medals will be awarded to the player. However, an upper limit (15 in this embodiment) is set for the number of medals to be awarded in one game, and when the total number of medals exceeds the upper limit, the upper limit number of medals is awarded. It will be. In addition, when a combination of symbols accompanied by a transition of the gaming state is stopped as a display result of each reel 2L, 2C, 2R on the winning line, the gaming state is shifted according to the combination of symbols. ing.

  In the slot machine 1 according to the present embodiment, after the game is started and the reels 2L, 2C, and 2R are rotated and the symbols start to change, any one of the stop switches 8L, 8C, and 8R is operated. When this is done, the rotation of the reels corresponding to the stop switches 8L, 8C, 8R is stopped, and the symbols are stopped and displayed. The maximum stop delay time from the operation of the stop switches 8L, 8C, 8R to the stop of the rotation of the corresponding reels 2L, 2C, 2R is 190 ms (milliseconds).

  The reels 2L, 2C and 2R rotate 80 times per minute, and 80 × 21 (the number of symbols per reel) = 1680 frames, so the maximum of 4 symbols is drawn in 190 ms. Will be able to. In other words, the symbols that can be selected as the stop symbols are the symbols that are displayed when the stop switches 8L, 8C, and 8R are operated, and the symbols that are four frames ahead of them, for a total of five symbols.

  For this reason, for example, when any one of the stop switches 8L, 8C, 8R is operated and the symbol displayed on the lower stage of the reel corresponding to the stop switch is used as a reference, the symbol from the symbol to four frames ahead is used. Since the symbols can be displayed in the lower row, in each of the reels 2L, 2C, 2R, when any one of the stop switches 8L, 8R is operated, the symbol displayed in the middle row of the reel corresponding to the stop switch. The symbols arranged within 5 frames including can be displayed on the winning line.

These electrical components are connected, and 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 main control unit 41, a control clock generation circuit 42, a random number clock generation circuit 43, a switch detection circuit 44, a motor drive circuit 45, a solenoid drive circuit 46, an LED drive circuit 47, and a power interruption detection circuit. 48 and a reset circuit 49 are mounted.

  The main control unit 41 is configured by a one-chip microcomputer, executes a control program stored in a ROM 506, which will be described later, and performs processing related to the progress of the game, and also includes a control circuit mounted on the game control board 40. Control each part directly or indirectly.

  The control clock generation circuit 42 generates a control clock CCLK serving as an oscillation signal having a predetermined frequency outside the main control unit 41. The control clock CCLK generated by the control clock generation circuit 42 is supplied to the clock circuit 502 via the control external clock terminal EXC of the main control unit 41 as shown in FIG. 5A, for example. The random number clock generation circuit 43 generates a random number clock RCLK that is an oscillation signal having a predetermined frequency different from the oscillation frequency of the control clock CCLK, outside the main control unit 41. The random number clock RCLK generated by the random number clock generation circuit 43 is supplied to the random number circuit 509 via the random number external clock terminal ERC of the main control unit 41 as shown in FIG. 5A, for example. As an example, the oscillation frequency of the random number clock RCLK generated by the random number clock generation circuit 43 may be set to be equal to or lower than the oscillation frequency of the control clock CCLK generated by the control clock generation circuit 42.

  The switch detection circuit 44 takes in detection signals input from switches connected directly to the game control board 40 or via the power supply board 101 and transmits them to the main control unit 41. The motor drive circuit 45 transmits the motor drive signal output from the main control unit 41 to the reel motors 32L, 32C, and 32R. The solenoid drive circuit 46 transmits the solenoid drive signal output from the main control unit 41 to the flow path switching solenoid 30. The LED drive circuit transmits the LED drive signal output from the main control unit 41 to various displays and LEDs connected to the game control board 40. The power interruption detection circuit 48 monitors the power supply voltage supplied to the slot machine 1 and outputs a voltage drop signal indicating that to the main control unit 41 when a voltage drop is detected. The reset circuit 49 provides a system reset signal to the main control unit 41 in a state where the power is unstable, such as when the power is turned on or when the power is turned off. The reset circuit 49 has a built-in watchdog timer 49a (see FIG. 5B). When the watchdog timer 49a times out, that is, when the operation of the CPU 505 of the main control unit 41 stops for a certain period of time, A user reset signal is given to the control unit 41.

  FIG. 5A shows a configuration example of the main control unit 41 mounted on the game control board 40. The main control unit 41 shown in FIG. 5A is a one-chip microcomputer, and includes an external bus interface 501, a clock circuit 502, a specific information storage circuit 503, a reset / interrupt controller 504, a CPU 505, and a ROM 506. A RAM 507, a CTC (counter / timer circuit) 508, a random number circuit 509, a PIP (parallel input port) 510, a serial communication circuit 511, and an address decode circuit 512.

  The external bus interface 501 provided in the main control unit 41 shown in FIG. 5A is an interface function between the external bus and the internal bus of the chip constituting the main control unit 41, the address bus, the data bus, and the direction of each control signal. A bus interface having a control function and the like. For example, the external bus interface 501 is connected to an external memory or an external input / output device externally attached to the main control unit 41, and transmits / receives address signals, data signals, various control signals, and the like to / from these external devices. Anything to do. In this embodiment, the external bus interface 501 includes an internal resource access control circuit 501A.

  The internal resource access control circuit 501A controls access to internal data of the main control unit 41 from an external device via the external bus interface 501, and stores internal data such as a game control program and fixed data stored in the ROM 506, for example. This is a circuit for limiting inappropriate external reading. Here, a circuit analysis device such as an in-circuit emulator (ICE) may be connected to the external bus interface 501 as an external device.

  The clock circuit 502 provided in the main control unit 41 is a circuit that generates the internal system clock SCLK by, for example, dividing the oscillation signal input to the control external clock terminal EXC by two. In this embodiment, the control clock CCLK generated by the control clock generation circuit 42 is input to the control external clock terminal EXC. The internal system clock SCLK generated by the clock circuit 502 is supplied to various circuits such as the CPU 505 that control the progress of the game in the main control unit 41. The internal system clock SCLK is also supplied to the random number circuit 509 and used to monitor the frequency of the random number clock RCLK supplied from the random number clock generation circuit 43. Further, the internal system clock SCLK may be output from the system clock output terminal CLKO connected to the clock circuit 502 to the outside of the main control unit 41. It is desirable that the internal system clock SCLK is not output to the outside of the main control unit 41. As described above, by limiting the external output of the internal system clock SCLK, it becomes difficult to specify the operation cycle of the internal circuit (such as the CPU 505) of the main control unit 41 from the outside. In the case of updating by this, it is possible to prevent the random number update cycle from being specified externally.

  The unique information storage circuit 503 included in the main control unit 41 is a circuit that stores a plurality of types of unique information serving as internal information of the main control unit 41, for example. As an example, the unique information storage circuit 503 stores three types of unique information such as a ROM code, a chip individual number, and an ID number. The ROM 506 code is a 4-byte numerical value generated from stored data in a predetermined area of the ROM 506, and four numerical values with different generation methods may be prepared. The chip individual number is a 4-byte number assigned when the main control unit 41 is manufactured, and indicates a different numerical value for each chip constituting the main control unit 41. The ID number is an 8-byte number assigned when the main control unit 41 is manufactured, and indicates a different numerical value for each chip constituting the main control unit 41. Here, it is sufficient that the chip individual number can be read from the user program while the ID number cannot be read from the user program. The unique information storage circuit 503 may be included in the ROM 506 by using a predetermined area of the ROM 506, for example. Alternatively, the unique information storage circuit 503 may be included in the CPU 505 by using a built-in register of the CPU 505, for example.

  The reset / interrupt controller 504 provided in the main control unit 41 is for controlling various resets and interrupt requests generated inside or outside the main control unit 41. The reset controlled by the reset / interrupt controller 504 includes a system reset and a user reset. The system reset is a reset that occurs when a low level signal (system reset signal) is input to the external system reset terminal XSRST for a certain period. The user reset is performed when a low level signal (user reset signal) is input to the external user reset terminal XURST for a certain period of time, or when a time-out signal of the built-in watchdog timer (WDT) is generated, or when running outside the specified area. This reset is caused by a predetermined factor such as the occurrence of prohibition (IAT). In this embodiment, as described above, since the watchdog timer (WDT) mounted on the reset circuit 49 is used without using the built-in watchdog timer, a user reset signal is input to the external user reset terminal XURST. Alternatively, a user reset occurs when the out-of-designated area travel prohibition (IAT) occurs.

  In this embodiment, as shown in FIG. 5B, a reset circuit 49 incorporating a watchdog timer 49a is mounted on the game control board 40. The reset circuit 49 outputs a system reset signal to the main control unit 41 until the power supplied to the slot machine 1 becomes a stable voltage and a predetermined time elapses. When the watchdog timer 49a times out, a user reset signal is output to the main control unit 41.

  As shown in FIG. 5 (B), in the game control board 40, among the signal lines connected from the LED drive circuit 47 to the credit display unit 11, the drive signals of the plurality of segments constituting the credit display unit 11 are below. The signal line of the 1 digit B segment signal, the lower 1 digit C segment signal, the upper 1 digit B segment signal, and the upper 1 digit C segment signal is branched and connected to the watchdog timer clear signal terminal of the reset circuit 49 via the or circuit. Has been.

  In the present embodiment, the main control unit 41 controls to dynamically light any one of the lower 1 digit B segment, the lower 1 digit C segment, the upper 1 digit B segment, and the upper 1 digit C segment of the credit indicator 11. In order to dynamically light these segments, if the main control unit 41 is operating normally, one of the drive signals of these four segments should be output periodically. It is possible to determine whether or not the main control unit 41 is operating normally by monitoring whether or not the drive signal of any one of the segments is periodically output.

  A signal obtained by combining the drive signals of these four segments into one via the or circuit is input to the watchdog timer clear signal terminal of the reset circuit 49, and the watchdog timer 49a is cleared. The output of the drive signals of the four segments is stopped, the watchdog timer 49a is not cleared, and the user reset signal is output to the main control unit 41 when time is up.

  As described above, in this embodiment, the segment signal of the LED to which the drive signal is given periodically is branched to clear the watchdog timer 49a, and the CPU 505 of the main control unit 41 individually monitors the watchdog timer 49a. This is preferable because it is possible to monitor whether or not the main control unit 41 is operating normally without performing the process of clearing the watchdog timer, but the watchdog timer clear signal terminal of the reset circuit 49 from the main control unit 41 The watchdog timer 49a may be cleared by inputting an individual clear signal.

  In this embodiment, the watchdog timer 49 a is mounted on the reset circuit 49 provided outside the main control unit 41. The operation of 41 may be monitored.

  Interrupts controlled by the reset / interrupt controller 504 include a non-maskable interrupt NMI and a maskable interrupt INT. The non-maskable interrupt NMI is an interrupt that is unconditionally accepted even when the CPU 505 is in an interrupt-disabled state. When a low level signal is input to the external non-maskable interrupt terminal XNMI (also used as the input port P4) for a certain period of time. An interrupt that occurs. The maskable interrupt INT is an interrupt that can permit / prohibit acceptance of an interrupt request by a setting instruction of the CPU 505, and multiple interrupts can be executed by setting priority. The maskable interrupt INT is caused by the fact that a low level signal is input to the external maskable interrupt terminal XINT (also used as the input port P3) for a certain period of time, a time-out occurs in the timer circuit included in the CTC 508, Multiple types of interrupt factors are determined in advance, such as the occurrence of an interrupt factor due to data transmission in the serial communication circuit 511 and the occurrence of an interrupt factor due to the acquisition of numerical data as a random value in the random number circuit 509. It should be.

  The CPU 505 provided in the main control unit 41 executes processing for controlling the progress of the game in the slot machine 1 by executing the program read from the ROM 506. At this time, the CPU 505 reads out fixed data from the ROM 506, the CPU 505 writes various data to the RAM 507 and temporarily stores the data, and the CPU 505 stores various data temporarily stored in the RAM 507. The CPU 505 receives the input of various signals from the outside of the main control unit 41 via the external bus interface 501 or the PIP 510, and the CPU 505 receives the input of various signals via the external bus interface 501 or the serial communication circuit 511. A transmission operation for outputting various signals to the outside of the main control unit 41 is also performed.

  As described above, in the main control unit 41, the CPU 505 executes control according to the program stored in the ROM 506. Therefore, the main control unit 41 (or CPU 505) executes (or performs processing) below. Specifically, the CPU 505 executes control according to a program. The same applies to microcomputers mounted on boards other than the game control board 40.

  A ROM 506 provided in the main control unit 41 stores a user program for game control, fixed data, and the like. The ROM 506 stores a security check program 506A. The CPU 505 reads the security check program 506A stored in the ROM 506 when the main control unit 41 shifts to the security mode in response to the power-on of the slot machine 1 or the occurrence of a system reset, and whether the storage content of the ROM 506 has been changed. Execute security check processing to check whether or not. The security check program 506A may be stored in a built-in memory different from the ROM 506. Further, the security check program 506A may correspond to a security check process for inspecting the storage content of the external memory externally attached to the main control unit 41 via the external bus interface 501, for example.

  A RAM 507 provided in the main control unit 41 provides a work area for game control. Here, at least a part of the RAM 507 may be a backup RAM backed up by a backup power source. That is, even if the power supply to the slot machine is stopped, at least part of the contents of the RAM 507 is stored for a predetermined period. In this embodiment, all areas of the RAM 507 are backup RAMs, and all contents of the RAM 507 are saved for a predetermined period even when power supply to the slot machine is stopped.

  The CTC 508 provided in the main control unit 41 includes, for example, an 8-bit programmable timer built in 3 channels (PTC0 to PTC2), and includes a timer circuit capable of generating a real-time interrupt and measuring time. Each programmable timer PTC0-PTC2 has a timer value that is updated in response to a change in the count clock signal generated based on the internal system clock SCLK (for example, a falling timing that changes from a high level to a low level). If it is good. In addition, the CTC 508 may incorporate, for example, an 8-bit programmable counter with 4 channels (PCC0 to PCC3). Each of the programmable counters PCC0 to PCC3 is only required to have its count value updated in response to a signal change of the internal system clock SCLK or occurrence of a timeout in any of the programmable counters PCC0 to PCC3. The CTC 508 resets the start time of the random number generated by the free run counter used for randomly determining the extension time (variable setting time) for extending the security time for each system reset or the random number circuit 509. A free-run counter or the like that is used to randomly determine each time may be included. Alternatively, these free-run counters may be included in an internal circuit of the main control unit 41 different from the CTC 508 such as a backup area of the RAM 507, for example.

  A random number circuit 509 included in the main control unit 41 is a circuit that generates numerical data that is a random value having a predetermined update range, such as a 16-bit random number. In the present embodiment, on the game control board 40 side, numerical data indicating a random value for internal lottery to be described later is controlled to be countable. In addition, in order to improve a game effect, random numbers other than these may be used. The CPU 505 uses a random counter different from the random number circuit 509 based on the numerical data extracted from the random number circuit 509 to process or update various numerical data by software, thereby indicating numerical data indicating a random value for internal lottery. May be counted. In the following, it is assumed that numerical data indicating random numbers for internal lottery is not processed by software from numerical data extracted by the CPU 505 from the random number circuit 509 serving as hardware. The random number circuit 509 may be incorporated in the main control unit 41 or may be externally attached to the main control unit 41 as a random number circuit chip different from the main control unit 41. .

  The random number for internal lottery is a value used to determine whether or not to allow a plurality of types of winnings, and takes a value in the range of “0” to “65535” in this embodiment.

  The PIP 510 included in the main control unit 41 is, for example, a 6-bit input dedicated port, and includes an input port P0 to an input port P2 serving as a dedicated terminal and an input port P3 serving as a function shared terminal and an input port P5. . The input port P3 is also used as an external maskable interrupt terminal XINT connected to the CPU 505 or the like. The input port P4 is also used as an external non-maskable interrupt terminal XNMI connected to the CPU 505 or the like. The input port P5 is also used as the first channel reception terminal RXA used by the serial communication circuit 511. The use setting of the input port P3 to the input port P5 is instructed by the function setting KFCS stored in the program management area.

  An address decoding circuit 512 provided in the main control unit 41 shown in FIG. 5 is a circuit for decoding each functional block in the main control unit 41 and a chip select signal that is a decoding signal for an external device. . By the chip select signal, an internal circuit of the main control unit 41 or an external device as a peripheral device is selectively operated effectively and can be accessed from the CPU 505.

  The ROM 506 provided in the main control unit 41 stores various selection data and table data used for controlling the progress of the game, in addition to the game control user program and the security check program 506A. For example, the ROM 506 stores data constituting a plurality of determination tables, determination tables, setting tables, and the like prepared for the CPU 505 to perform various determinations, determinations, and settings. The ROM 506 stores table data constituting a plurality of command tables used for the CPU 505 to transmit control signals serving as various control commands from the game control board 40.

  The RAM 507 provided in the main control unit 41 is provided with a game control data holding area 590 as an area for holding various data used for controlling the progress of the game in the slot machine 1. For example, a DRAM is used as the RAM 507, and a refresh operation is required to maintain the stored data contents. The CPU 505 has a built-in refresh register for performing this refresh operation. For example, the refresh register consists of 8 bits, and the lower 7 bits are automatically incremented each time the CPU 505 fetches an instruction from the ROM 506. Accordingly, the stored value in the refresh register is updated every execution time of one instruction in the CPU 505.

  The main control unit 41 transmits various commands to the sub control unit 91 via the serial communication circuit 511. A command transmitted from the main control unit 41 to the sub control unit 91 is sent in only one direction, and no command is sent from the sub control unit 91 toward the main control unit 41.

  The main control unit 41 receives the detection state of various switches connected to the game control board 40 from the input port. Then, the main control unit 41 executes basic processing that shifts in stages according to the detection states of various switches input from these input ports.

  Further, the main control unit 41 can execute an interrupt process by interrupting the basic process when an interrupt occurs. In the present embodiment, a timer interrupt process (main), which will be described later, is executed at a certain time interval (about 0.56 ms in the present embodiment) when a timeout occurs in the timer circuit included in the CTC 508.

  The main control unit 41 is set to prohibit other interrupts during the execution of the interrupt process, and when a plurality of interrupts occur at the same time, the main control unit 41 prioritizes according to a predetermined order. An interrupt to be executed is set. If another interrupt factor occurs during the execution of the interrupt process and the interrupt factor continues even after the interrupt process is completed, a new interrupt will occur at that point. It will be.

  The main control unit 41 repeatedly loops the process according to the control state until the detection state of the various switches connected to the game control board 40 changes as a basic process, and changes the detection state of the various switches. Execute a process that moves in stages. Further, the main control unit 41 executes a timer interrupt process (main) 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.

  An effect switch 56 is connected to the effect control board 90, and a detection signal of the effect switch 56 is input.

  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 driving circuit 93 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, When the power is turned on or when an initialization command from the sub CPU 91a is not input for a certain period of time, a reset circuit 95 that gives a reset signal to the sub CPU 91a and a detection signal input from the effect switch 56 connected to the effect control board 90 are detected. The switch detection circuit 96 outputs time information including date information and time information. The power supply voltage supplied to the timepiece device 97 and the slot machine 1 is monitored, and when a voltage drop is detected, a power drop detection circuit 98 that outputs a voltage drop signal to that effect to the sub CPU 91a, other circuits, etc. , And the sub CPU 91a receives various commands transmitted from the game control board 40 and performs various controls for performing effects, and directly controls each part of the control circuit mounted on the effect control board 90. To control automatically or indirectly.

  The reset circuit 95 has a lower voltage for releasing the reset signal than the reset circuit 49 that gives the system reset signal to the main control unit 41 in the game control board 40. When the power is turned on, the sub control unit 91 It starts at an earlier stage than the unit 41. On the other hand, the power interruption detection circuit 98 has a voltage that outputs a voltage drop signal lower than the power interruption detection circuit 48 that outputs a voltage drop signal to the main control unit 41 in the game control board 40. The sub control unit 91 detects a power failure at a later stage than the main control unit 41, and performs a power interruption process (sub) described later.

  Similar to the main control unit 41, the sub control unit 91 has an interrupt function, generates an interrupt when receiving a command from the main control unit 41, and acquires a command transmitted from the main control unit 41. Execute command reception interrupt processing to be stored in the buffer. Further, the sub control unit 91 executes an interrupt process (sub), which will be described later, by generating an interrupt every time the number of input system clocks reaches a certain number, that is, every certain interval.

  Also, unlike the main control unit 41, the sub control unit 91 interrupts the process even when the timer interrupt process (sub) is being executed when an interrupt is generated based on the reception of the command. 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.

  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 507 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 507 of the main control unit 41, and the state shifts to a state in which the game can proceed.

  In order to check the set value, after the game is over, the setting key switch 37 may be turned on in a state where the bet amount is not set. When the setting key switch 37 is turned on in such a situation, the setting value read out from the RAM 507 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 setting 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, the main control unit 41 determines whether or not the voltage drop signal from the power interruption detection circuit 48 is detected every time the timer interruption process (main) is executed. If the determination process is performed and it is determined that the voltage drop signal is detected in the power failure determination process, the power interruption process (main) is executed. In the power interruption process (main), the register is saved in a stack of a RAM 507, which will be described later, and destructive diagnosis data (in this embodiment, 5AH) in which any bit is 1 is stored in the RAM 507, that is, specific data other than 0 is stored. In addition to the storage, the RAM parity adjustment data is calculated so that the RAM parity based on the data stored in all areas of the RAM 507 becomes 0 and stored in the RAM 507. The RAM parity is a value calculated as an exclusive OR of the values stored in each bit of the corresponding area (all areas in this embodiment) of the RAM 507. For this reason, if the RAM parity based on the data stored in all areas of the RAM 507 is 0, the RAM parity adjustment data is 0, and the RAM parity based on the data stored in all areas of the RAM 507 is 1. In this case, the RAM parity adjustment data is 1.

  The main control unit 41 calculates the RAM parity based on the data stored in all areas of the RAM 507 at the time of activation, regardless of whether the system reset or the user reset, and the value of the data for destructive diagnosis And the processing state of the main control unit 41 is restored to the state before the power interruption based on the data stored in the RAM 507 on the condition that the RAM parity is 0 and the value of the data for destruction diagnosis is also correct. However, if the RAM parity is not 0 (in the case of 1) or the value of the destruction diagnosis 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. However, the progress of the game is disabled. Unlike the normal error state, 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 above-described setting change state. It will not be released until

  In this embodiment, all data stored in the RAM 507 is held by the backup power source even in the event of a power failure, and the main control unit 41 determines that the data in the RAM 507 is normal when the power is turned on. In addition, the configuration is such that the control state before power interruption is restored based on the data stored in the RAM 507. However, only the data stored in the RAM 507 that is necessary for returning to the control state in the event of a power failure is backed up and the power is turned on. It may be configured to return to the control state before power interruption based on the data backed up at the time.

  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.

  Next, initialization of the RAM 507 of the main control unit 41 will be described. The storage area of the RAM 507 of the main control unit 41 is divided into important work, non-saved work, general work, special work, unused area, and stack area.

  Important work items include various indicators, LED display data, I / O input / output data, game time counters, and other data that can be inconvenient to initialize, as well as the RT flag and RT remaining game count described below. Work to be done. 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 507 is destroyed at the time of activation. 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, the total number of medals paid out in the BB, and a game state flag described later. The special work is a work that stores data such as various software random numbers that are initialized only before the setting is started. The unused area is an unused area in the storage area of the RAM 507, 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 control unit 41 is stored, and the unused stack area is one of a plurality of initialization conditions to be described later, like the unused area. However, if it is established, it will be initialized, but the in-use stack area is not initialized because the program continues.

  In this embodiment, the main control unit 41 stores the data in the RAM 507 when the setting key switch 37 is turned on, when a RAM error occurs, when the BB ends, and when the setting key switch 37 is turned off. When not being destroyed, when five initialization conditions at the end of one game are satisfied, four types of initializations that are initialized in accordance with each initialization condition are performed.

  Initialization 1 is an initialization performed when the setting key switch 37 is turned on at the time of startup and transitions to a setting change state, or initialization performed when a RAM abnormality error occurs. In the storage area of the RAM 507, all areas (including the unused area and the unused stack area) except for the important work and the used stack area, that is, the area from the unsaved work to the unused stack area are initialized. The Initialization 2 is initialization performed at the end of the BB. In initialization 2, the area of the RAM 507 includes the general work, the unused area, and the unused stack area, that is, the area from the general work to the unused stack area. It is initialized. Initialization 3 is an initialization performed when the setting key switch 37 is in an off state at the time of startup and the data in the RAM 507 is not destroyed. In the initialization 3, the unsaved work, the unused area, and the 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 507 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.

  As described above, in this embodiment, when a RAM abnormality error occurs at the time of power-on or the like, initialization 1 is executed, and the control state before that is initialized. The RT flag and the RT remaining game number assigned to are held without being initialized. On the other hand, the gaming state flag assigned to the general work is initialized as initialization 1 is executed.

  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 the present embodiment, as will be described later, there are a regular bonus (hereinafter referred to as RB) and a normal gaming state as a gaming state, and 3 is defined as the prescribed number of bets in any gaming state. Regardless of the gaming state, when 3 is set as the bet number, the game can be started. In the present embodiment, all of the pay lines L1 to L5 are activated when a specified number of bets corresponding to the gaming state are set.

  In the slot machine 1 of this embodiment, when all the reels 2L, 2C, 2R are stopped, a winning combination is obtained when a combination of symbols called “comb” is arranged on the activated winning line (hereinafter simply referred to as a winning line). It becomes. 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 to win each winning combination determined according to the game state, it is necessary to win an internal lottery described later and set a winning flag for the winning combination in the RAM 507.

  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 the combination of combinations permitted by the flag is complete, and is invalid in a game having the combination of combinations permitted. In other words, once the winning flag for a special role is won, even if the combination of characters allowed by the flag cannot be aligned, the winning flag is not invalidated and is carried over to the next game. It becomes.

  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 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 value for internal lottery (an integer from 0 to 65535) is acquired when the start switch 7 is detected. Specifically, the value of the random number storage work assigned to the RAM 507 is set to the lottery work assigned to the RAM 507. Then, for each combination determined according to the gaming state and whether or not the special combination is carried over, the numerical data stored in the lottery work, the value of the gaming state flag for specifying the gaming state, and the RT described later are specified. The determination is made according to the number of determination values of each combination determined according to the value of the RT flag, the number of bets, and the set value.

  The random value storage work is a storage area in which numerical data latched simultaneously with the operation of the start switch 7 is stored. Every time new numerical data is latched, the latched numerical data is processed by a timer interruption process thereafter. The numerical data read in (main) and stored in the random value storage work is updated to the latest numerical data latched newly.

  In the internal lottery, an internal lottery target, a current gaming state flag value, an RT flag value, and the number of determination values determined corresponding to the set value are stored in a random number for internal lottery (a lottery work). When the result of addition overflows, it is determined that the winning combination is 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 winning combination is set in the internal winning flag storage work assigned to the RAM 507. The internal winning flag storage work consists of a 2-byte storage area, of which the upper byte is assigned as the special role storing work in which the winning flag for the special role 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 control unit 41 refers to the table index and the table creation data stored in the ROM 506 when the rotation of the reel starts and when the reel stops and the reel that is still rotating still remains. A stop control table is created for each reel that is rotating. 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 the system. 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 the present embodiment, a stepping motor that makes one turn at a cycle of 336 steps (0 to 335) is 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 control unit 41 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 is described. To explain, when any operation corresponding to the rotating reel is detected effectively among the stop switches 8L, 8C, 8R, the stop operation position is based on the number of steps from the reel reference position when the stop operation is detected. The number of sliding symbols corresponding to the area number of the specified stop operation position is acquired by referring to the stop control table of the reel where the stop operation is detected. 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 drawing in a maximum of 4 symbols after detecting a 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 a special role and a small role are elected at the same time, such as when a special role is elected while the special role has been carried over from before the previous game, the winning small role is the maximum in the range of 4 frames on the winning line. The number of sliding frames is fixed so that it can be drawn to the limit, and for the stop operation position where the selected small role cannot be drawn in the range of up to 4 frames in the winning line, the winning special role is in the range of 4 frames in the winning line Then, 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 can't draw a small role that has been won in the drawing range of up to 4 frames on the line, if you can stop with a special role that has been won in the drawing range of up to 4 frames on the winning line, A control is performed to stop them in a uniform manner, and a winning combination that has not been won will be controlled to be stopped within a 4-frame pull-in range. That is, in such a case, priority is given to the control for aligning the small combination on the winning line over the special combination, and the special combination can be won only when the small combination cannot be drawn. When a special combination and a small combination can be withdrawn at the same time, only the small combination is drawn in, and the small combination is not aligned on the winning line at the same time as the special combination.

  In this example, when a special role is elected while the special role has been carried over from before the previous game, or when a special role and a small role are simultaneously elected, the special role and the small role are won simultaneously. If the selected special role is given priority over the selected special role, the special role is controlled on the winning line only when the small role cannot be withdrawn. When winning simultaneously, priority is given to the control for aligning the special role on the winning line over the small role, and the control for aligning the small role on the winning line may be performed only when the special role cannot be drawn.

  If a special player and a replaying player are elected at the same time, such as when a replaying player is elected while the special role has been carried over from before the previous game, when the stop operation is performed, In addition, a control is performed in which the symbols of the re-gamer are aligned and stopped within a drawing range of up to 4 frames. In this case, the symbols constituting the re-gamer or the symbols constituting the re-gamer to be simultaneously elected are arranged at intervals of 5 symbols or less, that is, within 4 frames, for any of the reels 2L, 2C, and 2R. Since it can always be stopped at any position within the 4-frame pull-in range, if the special combination and the re-playing combination are elected at the same time, the timing of the operation of the stop switches 8L, 8C, 8R by the player Without fail, the re-playing role will always be won. 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 the case where the special combination and the re-playing combination can be withdrawn at the same time, only the re-playing combination is drawn in, and the special combination is not arranged on the winning line at the same time as the re-playing combination.

  In this embodiment, after the rotation of the reels 2L, 2C, and 2R is started, the main control unit 41 rotates the reels for which the stop operation has not been detected yet until the operation of the stop switches 8L, 8C, and 8R is detected. Continuously, on the condition that the operation of the stop switches 8L, 8C, and 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 control unit 41 transmits to the sub control unit 91 will be described.

  In this embodiment, the main control unit 41 sends a BET command, a credit command, an internal winning command, a freeze command, a reel rotation start command, a reel stop command, a winning determination command, a payout start command, a payout end to the sub control unit 91. A plurality of types of commands including commands, gaming state commands, standby commands, stop commands, error commands, return commands, setting commands, setting confirmation commands, door commands, and operation detection commands are transmitted.

  These commands consist of 1-byte type data indicating the command type and 1-byte extension data indicating the command content, and the sub-control unit 91 can determine the command type 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 MAXBET switch 6 is operated to set the number of bets 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 that has been 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 freeze command is a command indicating whether or not to control the freeze state when it is determined to control to the freeze state described later, and the timing when controlling to the freeze state. Sometimes sent.

  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 or the like of the next game, and is transmitted at the end of the game.

  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 control unit 41 has returned to the control state before the power interruption, and is transmitted when the main control unit 41 returns to the control state before the power interruption.

  The setting command is a command indicating the start or end of the setting change state and the setting value after the setting change. At the time of transition to the setting change state, a setting command indicating the start of the setting change state is transmitted, and when the setting change state ends. A setting command indicating the end of the setting change state and the setting value after the setting change is transmitted. Further, since the control state of the main control unit 41 is initialized with the transition to the setting change state, it can be specified that the control state of the main control unit 41 has been initialized by the setting command indicating the start of setting. .

  The setting confirmation command is a command that indicates the start or end of the setting confirmation state. A setting confirmation command that indicates the start of setting confirmation is transmitted when entering the setting confirmation state, and the setting confirmation end is indicated when the setting confirmation state ends. A confirmation command is sent.

  The door command is a command indicating the detection state of the door opening detection switch 25, that is, on (open state) / off (closed state), when the power is turned on, at the end of one game (after the game is over, the bet number of the next game) Sent before the setting of ”can be started), and when the detection state of the door opening detection switch 25 changes (from on to off, from off to on).

  The operation detection command is a switch in which the detection state (on / off) has changed among the operation switches (MAXBET switch 6, start switch 7, stop switch 8L, 8C, 8R), whether the detection state has changed from off to on, This command indicates whether the state has changed from on to off and the detection state (on / off) of another switch, and is transmitted when the detection state of any of these operation switches has changed.

  Of these commands, commands other than the door command and the operation detection command are generated in the basic process, and the command data in the command buffer assigned to the non-initialized area is updated to the newly generated command data, and the serial communication circuit The data is transmitted to the sub-control unit 91 by being transferred to the transmission data register 561 of 511.

  On the other hand, the door command is generated in the door monitoring process of the timer interrupt process (main) and stored in the door command storage area. The door command storage area stores a door command indicating the detection state of the door opening detection switch 25 at the time of power-on or at the end of one game, and when the detection state of the door opening detection switch 25 changes, A door command indicating the detection state is stored. Further, the door command stored in the door command storage area is not cleared even after the door command is transmitted, and is then overwritten by a newly stored door command. When the power is turned on or one game is finished, a door command transmission request 1 for requesting transmission of a door command stored in the door command storage area is set, and whether the door command transmission request 1 is set or whether the door is open is detected. When the detection state of the switch 25 changes, the door command transmission request 2 is set. When the door command transmission request 2 is set, the door command stored in the door command storage area is set. In the command transmission process of the timer interrupt process (main) executed after transmission is commanded, it is stored in the command buffer and transferred to the serial communication circuit 511 to be transmitted to the sub-control unit 91.

  The operation detection command is used when a change in the detection state of any switch is detected in the switch input determination process of the timer interrupt process (main) (when edge data of any switch is set). Is generated and stored in the operation detection command storage area, and when an operation detection command transmission request is set, transmission of the operation detection command stored in the operation detection command storage area is instructed, and a timer allocation executed thereafter In the command transmission process of the loading process (main), it is stored in the command buffer and transferred to the serial communication circuit 511 to be transmitted to the sub-control unit 91.

  As described above, both the door command and the operation detection command are stored in the command buffer in the command setting process of the timer interrupt process (main), transferred to the serial communication circuit 511, and transmitted to the sub-control unit 91. However, when the door command transmission request 2 is set, that is, when transmission of the door command is requested, priority is given to transmission of the door command even if transmission of the operation detection command is requested. Since the operation detection command is transmitted only when the door command transmission request 2 is not set, the door command transmission request 2 and the operation detection command transmission request are both set. In the command transmission process, the door command is transmitted, and the operation detection command is transmitted in the next command transmission process. So that the de is transmitted.

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

  When the sub control unit 91 receives a command from the main control unit 41, the sub control unit 91 executes a command reception interrupt process. 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.

  The reception buffer is provided with an area capable of storing a maximum of 16 commands so that a plurality of commands can be accumulated.

  In the timer interrupt process (sub), the sub-control unit 91 determines whether or not an unprocessed command is stored in the reception buffer. If an unprocessed command is stored, the sub-control unit 91 is the earliest. The control pattern table stored in the ROM 91b is referred to based on the command received in the stage, and the liquid crystal display 51, effect effect LED 52, speakers 53, 54, reel LED 55, etc. are controlled based on the control contents registered in the control pattern table. Performs output control of various rendering devices.

  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. Control patterns of these effect devices are registered, and when the sub-control unit 91 receives a command, the sub-control unit 91 stores the control patterns registered corresponding to the effect patterns set in the RAM 91c in the game of the control pattern table. Among these, the control pattern corresponding to the type of the received command is referred to, and the 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-control unit 91 receives a new command during execution of an effect triggered by the reception of a certain command, the sub-control unit 91 stops the effect based on the control pattern being executed, and changes to the newly received command. An effect based on the corresponding 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 received 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 the betting number setting operation is performed during the execution of the effect, that is, when the sub-control unit 91 receives a BET command indicating that the bet number has been set, Is to be canceled. 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 betting amount adjustment operation is performed during the performance, that is, after the sub-control unit 91 receives a game state command indicating the end of the game, it receives an internal winning command indicating the start of the game. When the payout start command is received before, the effect 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, and when the sub control unit 91 receives the internal winning command, the sub control unit 91 stores the effect pattern in the effect table according to the result of the internal lottery indicated by the internal winning command. With reference to the registered selection rate, one of the effect patterns 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 slot machine 1 according to the present embodiment, a winning is awarded when the winning symbols are aligned on any winning line. The types of winning combinations are determined according to the state of the game, but can be broadly divided into special roles with transition to big bonus and regular bonus, small roles with payout of medals, and setting of bet number. There is a re-player who can start the next game without needing.

  The big bonus may be indicated as BB and the regular bonus may be indicated as RB. In some cases, a big bonus or a regular bonus is simply referred to as a bonus. In order for each winning combination determined according to the gaming state to occur, it is necessary to set a winning flag in the RAM 507 to win the internal lottery and allow the winning of the winning combination.

  In the slot machine 1 according to the present embodiment, a winning is awarded when the winning symbols are aligned on any winning line. The types of winning combinations are determined according to the state of the game, but can be broadly divided into special roles with transition to big bonus and regular bonus, small roles with payout of medals, and setting of bet number. There is a re-player who can start the next game without needing.

  The big bonus may be indicated as BB and the regular bonus may be indicated as RB. In some cases, a big bonus or a regular bonus is simply referred to as a bonus. In order for each winning combination determined in accordance with the gaming state to occur, the winning flag indicating that the winning of the winning combination is permitted in the internal lottery described above needs to be set in the RAM 507.

  As the role in the slot machine 1, as shown in FIG. 6, a regular bonus as a special role (hereinafter, the regular bonus is RB), a big bonus (1) (2) (hereinafter, a big bonus is BB (1) (2)), watermelon, cherry, and bell are defined as small roles, and replay is defined as a replay role.

  In any gaming state, a cherry is placed on any of the winning lines on the left reel when a combination of “Cherry-ANY-Bell” or “Cherry-ANY-Replay” is aligned on the left reel, that is, on any of the winning lines on the left reel. When the “Cherry” symbol is derived and the “Bell” or “Replay” symbol is derived on the winning line of the right reel where “Cherry” is stopped on the left reel, it becomes a prize and two medals are paid out. .

  The watermelon is awarded when a combination of “watermelon-watermelon-watermelon” is aligned on any of the winning lines in any gaming state, and 15 medals are paid out.

  The bell is awarded when a combination of “bell-bell-bell” is arranged on any of the winning lines in any gaming state, and 12 medals are paid out.

  Replay is awarded when a combination of “replay-replay-replay” is arranged on the winning line in the normal gaming state. When the replay wins, no medals are paid out, but the next game can be started without setting the number of wagers again, so that three medals corresponding to the number of wagers that are not required to be set in the next game are paid out. Is essentially the same.

  RB is awarded when a combination of “net 7-net 7-black 7” is aligned on any of the winning lines in a gaming state other than RB, and the gaming state shifts to RB. The RB is a gaming state that is advantageous to the player over other gaming states by increasing the winning probability of the small role, especially the bell, and when the 12 games are digested after the RB starts, or a 4-game winning ( When the type of a combination is allowed), it ends either whichever comes first.

  BB (1) is awarded when a combination of “black 7-black 7-black 7” is aligned on any of the winning lines in a gaming state other than RB. BB (2) wins when a combination of “network 7-network 7-network 7” is arranged on any of the winning lines in a gaming state other than RB.

  When BB (1) (2) wins, the gaming state shifts to BB and simultaneously shifts to RB. When RB ends, if BB has not ended, it shifts to RB again and BB ends. Control is repeated until RB. That is, during BB, it is always controlled to RB. The BB ends when the total number of medals paid out to the player in the BB exceeds 480. At the end of the BB, the RB is also ended regardless of whether or not the RB end condition is satisfied.

  Next, with reference to FIG. 7, the combination of the lottery object combination read as the lottery object role for each gaming state will be described.

  In this embodiment, depending on whether the gaming state is the normal gaming state or RB (BB), the role is subject to the internal lottery, and in the normal gaming state, whether the special role is being carried over or not ( The target of the internal lottery also differs depending on the normal game state in which the special role is not carried over and the winning: normal game state in which the special role is carried over. As will be described later as a lottery target combination, a plurality of winning combinations can be read out simultaneously and can be won in duplicate. In FIG. 12 to FIG. 16, by indicating “+” between winning combinations, it indicates that they are simultaneously read out as a lottery target combination in the internal lottery.

  In FIG. 7, the lottery target combination is shown in the vertical column, and the gaming state is shown in the horizontal column. In the column where the gaming state intersects with the lottery target, a circle indicates that the lottery target is read out in the gaming state, and a cross indicates the lottery target when in the gaming state. This indicates that the combination is not read out.

  RB, BB (1), BB (2), RB + watermelon, RB + cherry, BB (1) + watermelon, BB (1) if the gaming state is the normal gaming state and the special role is not carried over + Cherry, BB (2) + Watermelon, BB (2) + Cherry, Replay, Watermelon, Cherry, and Bell are eligible for the internal lottery.

  If the gaming state is the normal gaming state and the special combination is carried over, replay, watermelon, cherry, and bell will be the target for internal lottery.

  If the gaming state is RB (BB), watermelon, cherry, and bell are the subject of the internal lottery.

  In the internal lottery, as described above, the number of judgment values determined in accordance with the internal lottery target, the current gaming state and the set value are sequentially added to the random number for the internal lottery, and the addition result 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.

  In this embodiment, as shown in FIG. 7, the winning probability of RB + watermelon is A1, the winning probability of BB (1) + watermelon is A2, the winning probability of BB (2) + watermelon is A3, and the winning probability of watermelon is A4. RB + Cherry win probability is B1, BB (1) + Cherry win probability is B2, BB (2) + Cherry win probability is B3, Cherry win probability is B4, and special role (RB, BB ( 1), BB (2)) + the ratio of special role + watermelon winning probability (A1 + A2 + A3) in the combined value of the winning probability of watermelon and the winning probability of watermelon (A1 + A2 + A3 + A4) is the special role (RB, BB (1 ), BB (2)) + the ratio of the winning probability of cherry and the winning probability of cherry (B1 + B2 + B3 + B4) is higher than the ratio of special role + cherry winning probability (B1 + B2 + B3) , A1~4, the probability of B1~4 are determined, respectively.

  For this reason, the percentage of winning watermelon is higher when the watermelon is winning than when the cherry is winning, and the watermelon is winning more than when the cherry is winning. If you are, you can expect to win special roles.

  In the present embodiment, the sub-control unit 91 performs an effect that suggests the possibility of winning the special role over a plurality of games, and finally executes a continuous effect that leads to an effect result indicating whether or not the special role is won.

  The sub-control unit 91 executes a continuous production lottery at the time of winning a cherry or watermelon with the possibility of winning simultaneously with the special role, and when winning any of the continuous productions of the production patterns 1 to 3, the winning production Perform continuous production of patterns.

  The effect pattern of the continuous effect is a pattern in which the display mode of the liquid crystal display 51, the sound output mode, the lighting mode of the LED, and the like differ depending on each effect pattern, and the difference can be recognized. In addition, the production pattern 0 indicates a losing of the continuous production. When the production pattern 0 is won, the continuous production is not executed, and when the production pattern 0 is won during the continuous production as described later. The continuous production being executed will continue.

  In addition, in the present Example, although the display aspect of the liquid crystal display 51, the output aspect of an audio | voice, and the lighting aspects, such as LED, are applied as a continuous effect, only any one of these effect aspects, Alternatively, any one of the two presentation modes may be used.

  In addition, the continuous production lottery is also executed when a cherry or watermelon that has the possibility of winning simultaneously with a special role is won during continuous production. When one of the continuous effects of patterns 1 to 3 is won, the continuous effect being executed is stopped and the continuous effect of the effect pattern newly won is executed. As will be described later, during the execution of the production pattern 3 in which the winning of the special role is confirmed, the continuous production lottery is not executed, and a new continuous production is not executed.

  In the continuous production lottery, as shown in FIGS. 8 to 12, the winning probabilities of the patterns 0 to 3 differ depending on whether or not the winning combination (whether or not the special role is won) and the continuous performance are being executed. In addition, if the continuous production is being executed, the winning probabilities of the patterns 0 to 3 differ depending on the winning combination (whether or not the special role is won) that triggered the continuous production and the production pattern of the continuous production being executed.

  Specifically, as shown in FIG. 8, the winning probabilities when a cherry alone wins in a state where continuous production is not being executed are 60% for pattern 0, 35% for pattern 1, 5% for pattern 2, and pattern 3 Is 0%, and the winning probability when the watermelon is won by itself without continuous performance is 40% for pattern 0, 40% for pattern 1, 20% for pattern 2, and 0% for pattern 3. In the case where cherry and special roles are won at the same time when continuous production is not being executed, the winning probability is 40% for pattern 0, 35% for pattern 1, 25% for pattern 2, and 0% for pattern 3. When the watermelon and the special combination are won at the same time without being executed, the winning probability is 20% for pattern 0, 40% for pattern 1, 40% for pattern 2, and 0% for pattern 3.

  In such a state where the continuous production is not being executed, the ratio of the production patterns 1 to 3 among the production patterns 0 to 3 is won at the same time as the special role than when the cherry or watermelon is won alone. If there is a higher effect, the continuous performance is executed when the cherry or watermelon is won, so that the expectation for winning the special role is higher than the case where the continuous performance is not executed.

  In addition, the proportion of the production patterns 1 and 2 in which the production pattern 2 is won is higher when the cherry or watermelon is won at the same time as the special role and is based on the production pattern 1. It is expected that the person who has performed the continuous production based on the production pattern 2 has won the special role rather than the continuous production.

  In addition, the ratio of the effect patterns 1 to 3 among the effect patterns 0 to 3 and the ratio that the effect pattern 2 of the effect patterns 1 and 2 is selected are watermelon> cherry, watermelon + special role> cherry + special role. The relationship is the same as the ratio that special roles are won together with cherry and watermelon. In other words, there is a higher possibility that a continuous production will be performed when a watermelon is won with a higher ratio of winning at the same time as a special role than when winning a cherry, and a cherry wins when a watermelon that can be expected to win a special role wins The direct production will be executed with a higher probability than when the performance was performed, and when the watermelon that can be expected to win the special role wins, the production of the production patterns 1 and 2 will be performed with a higher probability than when Cherry won. Since the continuous production based on the pattern 2 is executed, the continuous production based on the winning expectation degree of the special role at the time of winning the cherry and watermelon winning the continuous production, the execution probability of the continuous production, and the production pattern 2 As a result, the player's expectation for winning the special role can be effectively enhanced by the continuous performance.

  Further, as shown in FIG. 9 (a), the winning probability when the cherry wins alone during the execution of the continuous effect based on the effect pattern 1 triggered by the cherry alone is 60% for the pattern 0, the pattern 1 is 35%, pattern 2 is 5%, pattern 3 is 0%, and the probability of winning when a watermelon wins alone during the execution of continuous production based on production pattern 1 triggered by cherry alone is the pattern. 0 is 40%, pattern 1 is 40%, pattern 2 is 20%, pattern 3 is 0%, and cherry and special roles are won simultaneously during the execution of continuous production based on production pattern 1 triggered by cherry alone. The winning probability for pattern 0 is 35% for pattern 0, 35% for pattern 1, 25% for pattern 2, and 5% for pattern 3. Winning probability in the case of watermelon and special role in the continuous production run brute was simultaneously elected, pattern 0 is 20%, pattern 1 is 40%, the pattern 2 is 40%, the pattern 3 is 0%.

  Further, as shown in FIG. 9B, the winning probability when the cherry is won alone during execution of the continuous effect based on the effect pattern 2 triggered by the cherry alone is 95% for the pattern 0, the pattern 1 is 0%, pattern 2 is 5%, pattern 3 is 0%, and the probability of winning when a watermelon wins alone during the execution of continuous production based on production pattern 2 triggered by cherry alone is the pattern. 0 is 70%, pattern 1 is 0%, pattern 2 is 30%, pattern 3 is 0%, and cherry and special roles are simultaneously won during continuous production based on production pattern 2 triggered by cherry alone. In this case, the winning probability is 60% for pattern 0, 0% for pattern 1, 30% for pattern 2, and 10% for pattern 3, and is based on performance pattern 2 triggered by a single winning of cherry. Winning probability in the case of special auditors and watermelon during the execution of the continuous production was simultaneously elected, pattern 0 is 50%, pattern 1 is 0%, the pattern 2 is 50%, the pattern 3 is 0%.

  In addition, as shown in FIG. 10 (a), the winning probability is 95% for the pattern 0 when the cherry wins alone during the execution of the continuous effect based on the effect pattern 1 triggered by the single winner of the watermelon. 1 is 0%, pattern 2 is 5%, pattern 3 is 0%, and the winning probability when a watermelon wins alone during the execution of a continuous production based on the production pattern 1 triggered by a watermelon alone is the pattern 0 is 80%, pattern 1 is 0%, pattern 2 is 20%, pattern 3 is 0%, and cherry and special roles are simultaneously won during continuous production based on production pattern 1 triggered by a single selection of watermelon The winning probability is 70% for pattern 0, 0% for pattern 1, 30% for pattern 2, and 0% for pattern 3, and is a continuous performance based on performance pattern 1 triggered by a single watermelon winning. The winning probability in the case of special auditors and watermelon during execution was co-winner of, pattern 0 is 55%, pattern 1 is 0%, the pattern 2 is 40%, the pattern 3 of 5%.

  In addition, as shown in FIG. 10 (b), the winning probability when the cherry wins alone during the execution of the continuous production based on the production pattern 2 triggered by the watermelon alone is 100% for the pattern 0, the pattern 1 is 0%, pattern 2 is 0%, pattern 3 is 0%, and the winning probability when a watermelon wins alone during execution of a continuous production based on the production pattern 2 triggered by a watermelon alone is the pattern 0 is 80%, pattern 1 is 0%, pattern 2 is 20%, pattern 3 is 0%, and cherry and special roles are won simultaneously during the execution of continuous production based on production pattern 2 triggered by a single selection of watermelon In this case, the winning probability is 70% for pattern 0, 0% for pattern 1, 30% for pattern 2, and 0% for pattern 3, and is based on production pattern 2 triggered by a single watermelon winning. Winning probability in the case of special auditors and watermelon during the execution of the out was co-winner, the pattern 0 is 60%, pattern 1 is 0%, the pattern 2 is 30%, the pattern 3 is 10%.

  In addition, as shown in FIG. 11 (a), the winning probability when a cherry alone wins during a continuous performance based on the performance pattern 1 triggered by simultaneous winning of cherry and a special role is 80 for pattern 0. %, Pattern 1 is 0%, Pattern 2 is 10%, Pattern 3 is 10%, and a watermelon is elected independently during continuous performance based on performance pattern 1 triggered by simultaneous winning of cherry and special roles The winning probability is 70% for pattern 0, 0% for pattern 1, 30% for pattern 2, and 0% for pattern 3.

  In addition, as shown in FIG. 11 (b), the winning probability is 90 for pattern 0 when cherry wins alone during the execution of continuous production based on production pattern 2 triggered by simultaneous winning of cherry and special role. %, Pattern 1 is 0%, Pattern 2 is 0%, Pattern 3 is 10%, and a watermelon is elected alone during continuous production based on production pattern 2 triggered by simultaneous winning of cherry and special roles The winning probability is 80% for pattern 0, 0% for pattern 1, 20% for pattern 2, and 0% for pattern 3.

  Also, as shown in FIG. 12 (a), pattern 0 has a winning probability of 100 when cherry wins alone during execution of continuous production based on performance pattern 1 triggered by simultaneous winning of watermelon and special role. %, Pattern 1 is 0%, Pattern 2 is 0%, Pattern 3 is 0%, and when a watermelon is elected independently during continuous performance based on performance pattern 1 triggered by simultaneous selection of watermelon and special role The winning probability of pattern 0 is 80%, pattern 1 is 0%, pattern 2 is 10%, and pattern 3 is 10%.

  In addition, as shown in FIG. 12 (b), pattern 0 is 100% when a cherry is won independently during execution of a continuous production based on production pattern 2 triggered by simultaneous winning of watermelon and special role. When pattern 1 is 0%, pattern 2 is 0%, pattern 3 is 0%, and a watermelon is won by itself during the execution of continuous production based on production pattern 2 triggered by simultaneous winning of watermelon and special role The winning probability is 90% for pattern 0, 0% for pattern 1, 0% for pattern 2, and 10% for pattern 3.

  In this way, when cherry or watermelon with the possibility of winning simultaneously with a special role is won during the execution of continuous production that started with the winning of a cherry (including simultaneous winning with a special role) Cherries or watermelons that could be elected at the same time as the special role were elected during the execution of the continuous production that was triggered by the election of watermelons (including the simultaneous election with the special role) that were likely to be elected at the same time as the special role In such a case, the probability of newly winning a continuous production is set low.

  At this time, only the probability that the production pattern 1 is won is limited among the production patterns 1 and the continuous production 2 based on the pattern 2 having a higher expectation of winning the special role than the production pattern 1.

  Further, during the execution of the continuous production based on the production pattern 2 having a higher expectation of winning the special role than the production pattern 1, when the cherry or the watermelon is won, only the production pattern 2 can be won. The continuous production based on the production pattern 2 is stopped, and the continuous production based on the production pattern 1 with a low expected expectation is not newly started.

  In addition, during the execution of the continuous production that was triggered by the watermelon election, the execution of the continuous production that was triggered by the winning of the cherry than the case where the cherry that is less likely to have won the special role than the watermelon is elected The probability that a continuous production is newly won is higher when the cherry is won.

  In addition, it is determined that the probability that a continuous production will be newly elected is different between the case where a special role is won at the start of continuous production and the case where a special role is not won at the start of continuous production. ing. In particular, if a special role is won after the start of a continuous performance, the probability that a continuous role will be newly won is greater when a special role is won after winning a cherry or watermelon after the start of the continuous performance. It is set to be high.

  In addition, the production pattern 3 is determined so that, during execution of the continuous production, the same role as the opportunity for starting the continuous production is won and can be won only when the special role is won. .

  In this example, since a configuration in which a continuous production is newly executed when a cherry or watermelon that may be elected simultaneously with a special role is won during execution of the continuous production, after the start of the continuous production. A role that has a higher chance of winning a special role than the role that triggered it is won and a new continuous performance is executed, or a continuous performance with a higher expectation of winning than the continuous performance being executed is executed. As a result, while the new continuous performance can increase the player's expectation for the special role, the role that is lower than the possibility of winning the special role suggested by the role that triggered the initial continuous performance For example, in a continuous production that started with watermelon, the continuous production that is being executed is canceled when a cherry with a low possibility of winning a special role is elected, and a new continuous production starts, When the low winning expectation level than the continuous production of during their execution continuous production is or start, there is a fear that gives the impression that the winning expectation of the special role fell.

  On the other hand, in the present embodiment, as described above, even if a cherry or watermelon is won during the execution of a continuous production that is triggered by the winning of a watermelon that is likely to be simultaneously won with a special role rather than a cherry , Because the percentage of the continuous production being executed and the new continuous production being executed is lower than when the cherry or watermelon is won during the execution of the continuous production that was triggered by the winning of the cherry. Continuous production that started with the chance of winning a watermelon that is likely to be elected at the same time as a special role is canceled by a cherry that is less likely to win a special role than that, and the continuous production that starts with this cherry is started Therefore, it is possible to prevent the expectation for the winning of the special role suggested by the continuous performance during execution from being reduced.

  Also, in this embodiment, when a cherry or watermelon is won during execution of a continuous production based on pattern 1 that was started when a watermelon was won, a special role suggested by the production pattern of the continuous production currently being executed The new execution of the continuous production based on the production pattern 2 that suggests a higher expectation degree than the winning expectation is not limited, and the same winning as the special role of the special role suggested by the production pattern of the continuous production currently being executed Since only the new execution of the continuous production based on the production pattern 1 that suggests the degree of expectation is restricted, the continuous production being executed is changed to a continuous production that does not change the expectation of winning the special role in the middle. It is limited only to be performed, and there is no limit to a continuous production with a high expectation of winning the special role, that is, a change of the continuous production that can further enhance the player's expectation.

  In this embodiment, only the new execution of the continuous production based on the production pattern 1 suggesting the same winning expectation degree as the special role suggested by the special production effect pattern currently being executed is restricted. If there is a production pattern that has a lower expectation level for winning the special role than the production pattern 1, it is higher than the expectation level for winning the special role suggested by the continuous production direction pattern currently being executed. The new execution of the continuous production based on the production pattern 2 in which the degree of expectation is suggested is not limited, and the winning expectation degree lower than the winning expectation degree of the special role suggested by the production pattern of the continuous production currently being executed is suggested. Even if the configuration is such that only new execution of the continuous production based on the production pattern is restricted, the continuous production being executed may be changed to a continuous production with a lower expected expectation of the special role on the way. Only is limited, high winning expectations of special auditors continuous production, that never will be limited until the change of further continuous production which is to increase the player's expectation.

  Further, in this embodiment, during the execution of the continuous production based on the production pattern 2 having a higher expectation of winning the special role than the production pattern 1, when the cherry or watermelon is won, the continuous production based on the production pattern 2 is performed. The continuous production based on the production pattern 1 which is canceled and the expected expectation is low is not newly started, the continuous production currently being executed is canceled, and the special performance is more active than the continuous production currently being executed. By starting a continuous performance with a low expectation of winning, it is possible to prevent the expectation for winning the special role suggested by the continuous performance being executed from being reduced.

  In addition, in this example, the winning of the cherry starts more than the case where the cherry that won the special role is less likely to win the special role than the watermelon during the execution of the continuous production started with the winning of the watermelon Since the percentage of continuations that are being executed and a new continuous effect being executed is higher when the cherry wins during the execution of the continuous production, it was triggered by the winning of watermelon. During the execution of the continuous production, the continuous production being performed is canceled and changed to another continuous production because the cherry that is unlikely to win the special role is elected than the watermelon that triggered it While this can reduce the situation where the expectation of winning the first special role will be lost, while the continuous production that started with the winning of Cherry is running, But it does not change the winning potential of the special role by winning the ferry, by at least a new continuous production is started, it is possible to sustain the player's expectation for the winning of the special role.

  In this embodiment, only cherry and watermelon are applied as general roles that can be won at the same time as the special role. For example, the possibility of winning at the same time as the special role is higher than that of cherry and lower than that of watermelon. When the simultaneous winning combination is applied, the third simultaneous winning combination that is less likely to have won the special role than watermelon during the execution of the continuous production that started with the winning of watermelon is more than However, if the third simultaneous winning role that is likely to have won the special role is more elected than the cherry during the execution of the continuous production that was triggered by the winning of Cherry, It is preferable to set a high ratio of canceling and performing a new continuous production. By adopting such a configuration, during the execution of a continuous production that was triggered by the winning of a watermelon, Yo However, if the third simultaneous winning role that is unlikely to have won the special role is won, the continuous production being executed will be canceled and changed to another continuous production. While it is possible to reduce the situation where the expectation is lost, while the continuous production that was triggered by the winning of Cherry is being executed, the continuous production being executed by the third simultaneous winning combination is canceled. Since the possibility of changing to another continuous performance increases, the player's expectation for winning the special role can be effectively increased by changing to another continuous performance.

  Also, in this example, cherry or watermelon is won during the continuous production when the special role is won at the start of the continuous production and when the special role is not won at the start of the continuous production. Whether the special performance was selected from the beginning depending on whether or not the continuous production is changed when a cherry or watermelon is elected during the continuous production. You can guess whether or not.

  Also, if the special role is not elected at the start of the continuous performance, and the special role is elected from the start of the continuous performance if the cherry or watermelon is elected and the special role is elected during the continuous performance Since the continuous production will be changed at a higher rate, if the winning of the special role is announced after the start of the continuous production and the continuous production is not changed even if cherries and watermelons are elected, Despite being elected, it is possible to prevent the impression that the conclusion was unnecessarily extended due to the election of cherry or watermelon, while cherry and watermelon are elected after the start of continuous production If the directing is changed and the winning of the special role is announced, the possibility that the special role that was not won at the beginning was won by the winning of cherry or watermelon drawn in the middle will increase, so this Also useless Conclusions rather than been stretched, as a result of winning a special role, it is possible to continuously produce will give the impression that newly started.

  Further, in this embodiment, as the effect pattern of the continuous effect, an effect pattern 3 that can be selected only when the same role as the trigger for starting the continuous effect is won during execution of the continuous effect is defined. Thus, it is unlikely that the same role as the opportunity that started this continuous production will be won during the execution of the continuous production, and only when such a rare event has occurred, The player's satisfaction can be effectively enhanced by executing the continuous production based on the game.

  In particular, in the present embodiment, during the execution of the continuous production, the production pattern 3 is selected not only when the same role as the opportunity for starting the continuous production is won, but also when the special role is further won. Therefore, the rarity is further increased, and the winning of the special role is also confirmed, so that the player's satisfaction can be further enhanced.

  In the present embodiment, the continuous production being executed is canceled and the continuous production is started again by winning a cherry or watermelon that may be elected simultaneously with the special role during the execution of the continuous production. However, the performance that is executed again after stopping the continuous performance being performed is not limited to the same continuous performance, but may be any performance that suggests at least the possibility of winning the special role. May be different types of continuous performances, or may be an effect completed within one game suggesting the possibility of winning a special role.

  In addition, as a right that is advantageous to the player, a special role that accompanies the transition to the bonus, that is, a right that allows the player to enter a gaming state that is advantageous to the player is applied. Although directing that expects a special role to be won is applied, this is not limiting, and as a right that is advantageous to the player, there is a gaming state that is advantageous to a player other than the bonus, for example, the probability of winning a specific role than usual Increased information and noticed information advantageous to the player, such as an operation mode for deriving a stop mode advantageous to the player (a winning mode or a non-winning mode may be used). Winning an advantageous player with a transition to a gaming state where a large amount of gaming value can be expected, and the right to control these advantageous gaming states (control to advantageous state) A right to be notified of an operation mode for deriving a display result advantageous to the player may be applied. An effect suggesting the possibility that these rights are given as the effect and the interrupt effect may be applied.

  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.

  In the above-described embodiment, the example in which the present invention is applied to a slot machine in which bets are set using medals and credits as game values has been described.
