Description

  The present invention relates to a slot machine for playing games.

  A slot machine generally includes a variable display device having a plurality of (usually three) reels having a plurality of types of symbols as identification information drawn on the outer periphery thereof. First, a bet is set by a player's betting number setting operation. When a start operation is performed in a state where a predetermined number of bets is set, the reels start rotating, and a stop button as a derivation operation means provided corresponding to each reel is operated. Stop rotation. In normal games, when all reels stop rotating, a predetermined winning symbol combination (for example, 7-7-7, hereinafter referred to as a symbol combination) is derived on the winning line. Winning occurs. 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.

  There is also known a slot machine that performs advantageous RT control over a period of a plurality of games after a predetermined condition is established. In such a slot machine, when the number of remaining games until the advantageous RT is finished is less than the predetermined number of games, the execution of the continuous effect is prohibited and the derivation of the special display result is permitted in the single game effect. What performs the alerting | reporting effect which alert | reports that the effect is determined is known (for example, refer patent document 1).

  The reset / interrupt controller 506 is for controlling various resets and interrupt requests generated inside or outside the main control unit 41. The reset / interrupt controller 506 includes an out-of-designated area prohibition (IAT) circuit 506a and a watchdog timer (WDT) 506b. The IAT circuit 506a is a circuit that monitors whether the user program is correctly executed in the designated area, and has a function of outputting an IAT generation signal when it is detected that the user program is executed outside the designated area. The watchdog timer 506b has a function of generating a timeout signal for each set period.

  The external bus interface 501 is a bus interface having an interface function between an external bus and an internal bus of a chip constituting the main control unit 41, an address bus, a data bus, and a direction control function of each control signal. The clock circuit 502 is a circuit that generates the internal system clock SCLK by, for example, dividing the control clock CCLK by two. The verification block 503 is connected to an external verification machine and has a function of performing chip verification. The unique information storage circuit 504 is a circuit that stores a plurality of types of unique information that is internal information of the main control unit 41. The arithmetic circuit 505 is a circuit that performs multiplication and division.

  The CPU 41a is a control CPU that executes game control in the slot machine 1 by executing a user program (game control processing program for game control) based on the control code read from the ROM 41b. When such game control is executed, the CPU 41a reads fixed data from the ROM 41b, the variable data writing operation in which the CPU 41a writes various fluctuation data to the RAM 41c and temporarily stores them, and the CPU 41a is temporarily stored in the RAM 41c. A variable data reading operation for reading out various variable data being received, a receiving operation in which the CPU 41a receives input of various signals from the outside of the main control unit 41 via the external bus interface 501, the parallel input port 511, the serial communication circuit 512, etc. However, a transmission operation for outputting various signals to the outside of the main control unit 41 via the external bus interface 501, the serial communication circuit 512, the parallel output port 513, and the like is also performed.

  The ROM 41b stores a control code indicating a user program (game control processing program for game control), fixed data, and the like. The RAM 41c provides a work area for game control. Here, at least a part of the RAM 41c may be a backup RAM backed up by a backup power source. That is, even if the power supply to the slot machine 1 is stopped, at least a part of the contents of the RAM 41c is stored for a predetermined period.

  As the free-run counter circuit 507, an 8-bit free-run counter is mounted. The random number circuits 508a and 508b are circuits that generate numerical data that is a random value having a predetermined update range, such as an 8-bit random number or a 16-bit random number. In this embodiment, the hardware random number generated by the 16-bit random number circuit 508b among the random number circuits 508a and 508b is used as a random number for internal lottery described later. The timer circuit 509 is a 16-bit programmable timer, counts down the set timer value based on the input of the control clock CCLK, and outputs an interrupt request signal to the interrupt controller when reaching 0000h. In this embodiment, it is possible to perform periodic interrupt requests and time measurement using the timer circuit 509.

  The interrupt controller 510 is a circuit that controls external interrupt requests from interrupt terminals and interrupt requests from built-in peripheral circuits (for example, serial communication circuit 512, random number circuits 508a and 508b, timer circuit 509). . The parallel input port 511 incorporates an 8-bit wide input-only port. Further, the parallel output port 513 provided in the main control unit 41 shown in FIG. 5 incorporates an output-only port having an 11-bit width. The serial communication circuit 512 is a circuit that performs asynchronous serial communication in input / output with respect to the outside.

  The address decoding circuit 514 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. In response to the chip select signal, the internal circuit of the main control unit 41 or the external device serving as a peripheral device is selectively operated effectively and can be accessed from the CPU 41a.

  FIG. 6 is an address map of the memory area used by the main control unit 41. As shown in FIG. 6, the memory area used by the main controller 41 includes a memory area (0000h to 7FFFh) allocated to the RAM 41c and a memory area (8000h to FFFFh) allocated to the ROM 41b.

  The memory area of the RAM 41c includes an available area (0000h to 01FFh) that can be used as a work, and an internal function register area (1000h to 1000h) in which a register group for controlling each function installed in the main control unit 41 is stored. 1080h) and unused areas (0200h to 0FFFh, A800h to FFFFh) where access is prohibited.

  The memory area of the ROM 41b includes a program / data area (8000h to A6FFh) in which programs and fixed data are stored, a ROM comment area (A700h to A7FFh) in which arbitrary data such as a program title and version can be set, and CALLV. Vector table area (A780h to A7A7h) in which the start address of the instruction subroutine and the start address of the interrupt process are set, and the HW parameter in which parameters for setting the internal functions of the main control unit 41 are set in hardware It includes an area (addresses A7A8h to A7FFh) and an unused area (A800h to FFFFh) where access is prohibited.

  The parameters set in the HW parameter area include the final address (HPRGEND) of the ROM area used in the program / data area, the start address (HRAMSTAT) and the final address (HRAMEND) of the RAM area for which access is prohibited.

  When the main control unit 41 accesses an area between the address set in HPRGEND and A6FFh, that is, an area where no program or the like is stored in the program / data area, the main control unit 41 sets the address set in HRAMSTAT. To an area between addresses set in HRAMEND, that is, an area where access is prohibited among usable areas, an access to the ROM comment area, an access to the HW parameter area When there is an illegal access, an illegal access is determined and an illegal access reset is generated. When an illegal access reset occurs, the state is controlled to a special error state to be described later, the progress of the game is disabled, the state is changed to a setting change state, and is not canceled until a new set value is set.

  As described above, when the main control unit 41 accesses an area of the program / data area where no program or the like is stored, the main control unit 41 accesses an area of the usable area where access is prohibited. That is, when an access is made to a memory area that is not accessed in normal operation, an illegal access reset is generated to disable the progress of the game, so it is not related to an unused area or operation of the ROM 41b. Even if an unauthorized program is stored in the area, an unused area of the RAM 41c, etc., it is possible to prevent the unauthorized program from being executed.

  Further, the main control unit 41 is activated by the occurrence of a system reset by inputting a system reset signal, a WDT reset by the WDT 506b, or the aforementioned illegal access reset. At this time, the value set in the vector table area Is 0000h (value set in an unused vector table area) or an address area set in 8000h to HPRGEND, that is, a value indicating an area where a program or the like is actually stored in the program area. If the value set in the vector table area is neither 0000h nor the value indicating the address area set in 8000h to HPRGEND, the activation is not performed.

  As described above, the main control unit 41 is activated when the value set in the vector table area, that is, the start address of the subroutine of the CALLV instruction and the start address of the interrupt process are values indicating the outside of the area where the program is set. By not doing so, it is possible to prevent in advance processing that was not originally intended due to the occurrence of an interrupt or the like.

  The main control unit 41 transmits various commands to the sub control unit 91 via the parallel output port 513. 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. In the present embodiment, the command is transmitted to the sub-control unit 91 via the parallel output port 513, that is, the command is transmitted as a parallel signal, but the command is transmitted via the serial communication circuit 512. The command may be transmitted to the sub-control unit 91, that is, the command may be transmitted as a serial signal.

  The main control unit 41 also receives detection states of various switches connected to the game control board 40 from the parallel input port 511. The main control unit 41 executes basic processing that shifts in stages according to the detection states of various switches input from the parallel input port 511. 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 every time a time-out occurs in the timer circuit 509, that is, every fixed time interval (about 0.56 ms in the present embodiment). 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 (in the present embodiment, about 0.56 ms). In addition, the execution interval of the timer interrupt process (main) is set to a time longer than the sum of the time required to complete the repeated process according to the control state in the basic process and the execution time of the timer interrupt process (main) Therefore, the process that is repeated according to the control state between the current and next timer interrupt processes (main) is completed at least once.

  The effect control board 90 is connected to effect devices such as the liquid crystal display 51, the effect LED 52, the speakers 53 and 54, and the reel LED 55. These effect devices are sub-controls described later mounted on the effect control board 90. It is driven based on control by the unit 91. In the present 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, an output control unit that directly controls the output of the effect device is mounted on the effect control board 90 or another board separately from the sub control part 91, and the sub control part 91 is based on a command from the main control part 41. The output pattern of the effect device may be determined, 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 The output control of the effect device is performed by both of the control units. Moreover, in this Embodiment, although the liquid crystal display 51, the effect effect LED52, the speakers 53 and 54, and the reel LED55 are illustrated as an effect device, an effect device is not restricted to these, For example, it drives mechanically. A display device or a mechanically driven item may be applied as the rendering device.

  The effect control board 90 is composed of a microcomputer having a sub CPU 91a, ROM 91b, RAM 91c, and I / O port 91d, and a liquid crystal display connected to the effect control board 90, a sub control unit 91 for effect control. 51, a display control circuit 92 for performing display control, an LED driving circuit 93 for controlling driving of the effect LED 52 and the reel LED 55, an audio output circuit 94 for controlling audio output from the speakers 53, 54, when the power is turned on or from the sub CPU 91a The reset circuit 95 that gives a reset signal to the sub CPU 91a when the initialization command is not input for a certain period of time, the switch detection circuit 96 that detects the detection signal input from the switches connected to the effect control board 90, date information and time Clock device 97 for outputting time information including information, slot machine 1 The power supply voltage to be supplied is monitored, and when a voltage drop is detected, a power failure detection circuit 98 that outputs a voltage drop signal to that effect to the sub CPU 91a, and other circuits are mounted. In response to the command transmitted from the game control board 40, the CPU 91a performs various controls for performing an effect, and directly or indirectly controls each part of the control circuit mounted on the effect control board 90.

  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 input number of system clocks reaches a certain number, that is, every certain time interval (about 2 ms). 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 the set value in a lottery that affects the advantage to the player, such as an internal lottery, a navigation stock lottery, and an extra lottery to be described later. The set value is composed of 6 levels of 1 to 6, with 6 being the highest payout rate and the payout rate being lower as the value is decreased in the order of 5, 4, 3, 2, 1. That is, when 6 is set as the set value, the advantage is highest for the player, and as the value decreases in order of 5, 4, 3, 2, 1, the advantage decreases stepwise.

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

  In addition, when the setting key switch 37 is turned on and the power is turned on, the door opening detection switch 25 may detect that the front door 1b is opened, and shift to the setting change state. Well, by adopting such a configuration, it is possible to prevent unauthorized setting changes in a state where the front door 1b is not opened. Further, in the configuration that shifts to the setting change state on the condition that the detection corresponding to the opening of the front door 1b is performed, the door opening detection switch 25 supports the opening of the front door 1b after shifting to the setting change state. Even if the detection is not detected, it is preferable to maintain the setting change state. Thus, even if the front door 1b is temporarily closed during the setting change, an operation for shifting to the setting change state is performed again. This is not necessary, and the setting change operation is not complicated. Further, after the transition to the setting change state, when the setting value is determined by operating the start switch 7 and then the setting key switch 37 is turned OFF, the door opening detection switch 25 detects that the front door 1b is opened. On the condition that the setting change state is terminated, it may be configured to shift to a state in which the game can proceed. Even in such a configuration, the front door 1b is not opened in an unauthorized manner. It is possible to prevent the setting from being changed.

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

  It should be noted that, after the game is over, when the setting key switch 37 is turned on with no bet amount set, the door opening detection switch 25 detects that the front door 1b is opened. In addition, a configuration for shifting to the setting confirmation state may be adopted. By adopting such a configuration, it is possible to prevent the setting value from being illegally confirmed without the front door 1b being opened. In addition, in the configuration that shifts to the setting confirmation state on the condition that the detection corresponding to the opening of the front door 1b is performed, the door opening detection switch 25 supports the opening of the front door 1b after the transition to the setting confirmation state. It is preferable to maintain the setting confirmation state even if the detection to be performed is not performed. Thus, even if the front door 1b is temporarily closed during the setting confirmation, an operation for shifting to the setting confirmation state again is performed. This is not necessary and the setting confirmation operation is not complicated. Further, after shifting to the setting confirmation state, when the set key switch 37 is turned off after the set value is confirmed by operating the start switch 7, the detection corresponding to the opening of the front door 1b is performed by the door opening detection switch 25. On the condition that the setting confirmation state is terminated, it may be configured to return to a state in which the game can proceed, and even in such a configuration, the front door 1b is not opened in an unauthorized manner. It is possible to prevent the setting value from being confirmed.

  In the slot machine 1 of the present embodiment, the main control unit 41 determines whether or not a voltage drop signal from the power interruption detection circuit 48 is detected every time the timer interrupt process (main) is executed. Power failure determination processing is performed, and when it is determined that a voltage drop signal is detected in the power failure determination processing, power interruption processing for setting data for determining whether or not the data in the RAM 41c is normal at the time of the next recovery (main) Execute.

  Then, the main control unit 41 returns the processing state of the main control unit 41 to the state before the power interruption based on the data stored in the RAM 41c on the condition that the data in the RAM 41c is normal at the time of activation. However, if the RAM 41c data is not normal, 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, thereby disabling the progress of the game.

  The error state shifts to a normal error state that is canceled by a reset operation (operation of the reset / setting switch 38 or the reset switch 23) and the setting change state described above, and is canceled until a new setting value is set. Special error status with no error, the RAM abnormal error status is a special error status, and once it is controlled to the RAM abnormal error status, it shifts to the setting change status and is released until a new set value is set. It will not be done.

  Further, the sub control unit 91 also determines whether or not the voltage drop signal from the power interruption detection circuit 98 is detected in the timer interruption process (sub), and when it is determined that the voltage drop signal is detected, A power interruption process (sub) for setting data for determining whether or not the data in the RAM 91c is normal at the next return is executed.

  Then, the sub-control unit 91 returns the processing state of the sub-control unit 91 to the state before the power interruption based on the data stored in the RAM 91c on the condition that the data of the RAM 91c is normal at the time of activation. However, if the data in the RAM 91c is not normal, it is determined that the RAM is abnormal, and the RAM 91c is initialized. In this case, unlike the main control unit 41, only the RAM 91c is initialized, and the performance is not disabled.

  In addition, even when it is determined that the data in the RAM 91c is normal at the time of activation, the sub control unit 91 activates when receiving a setting command (described later) indicating that the setting change state has been entered from the main control unit 41. Even when a later-described return command or setting command indicating that the control state of the main control unit 41 has returned is not received even after a certain period of time has elapsed, the RAM 91c is initialized. In this case, the execution of the performance is not disabled only by initializing the RAM 91c.

  Next, initialization of the RAM 41c of the main control unit 41 will be described. The usable area in the storage area of the RAM 41c of the main control unit 41 is divided into an important work, a special work, a general work, an unused area, and a stack area, and an important work, a special work, a general work, and an unused area. Are arranged in the stack area order.

  In the present embodiment, the main control unit 41 detects the data in the RAM 41c when the setting key switch 37 is turned on when the setting key switch 37 is turned on. Is not destroyed, when the setting key switch 37 is turned on and the data in the RAM 41c is destroyed, at the end of setting change, at the end of a specific gaming state, and at the end of one game When the initialization condition consisting of is established, four types of initializations with different areas initialized according to each initialization condition are performed.

  Initialization 0 is when the data in the RAM 41c is destroyed when the setting key switch 37 is turned off and when the data in the RAM 41c is destroyed when the setting key switch 37 is turned on. In the initialization 0, all the usable areas are initialized. Initialization 1 is initialization that is performed when data in the RAM 41c is not destroyed at the time of start-up with the setting key switch 37 being ON. In the initialization 1, other than important work and special work in the usable area. This area is initialized. Initialization 2 is initialization performed at the end of a specific gaming state. In initialization 2, a general work, an unused area, and an unused stack area are initialized among available areas. Initialization 3 is initialization performed at the end of one game. In initialization 3, an unused area and an unused stack area are initialized among the available areas. The storage area for the data indicating the set value and the game state is allocated to the special work, and when the data in the RAM 41c is not destroyed at the time of startup with the setting key switch 37 being ON, that is, the data in the RAM 41c. When the game is normal and the setting is changed, data indicating the setting value and the gaming state is held. Further, a storage area for a timer counter, which will be described later, is allocated to a special work and is held without being initialized at the end of the game or at the end of a specific gaming state.

  In the slot machine 1 of the present embodiment, a prescribed number of bets that can be set is determined according to the gaming state, and on condition that the prescribed number of bets determined according to the gaming state is set. The game can be started. In the present embodiment, the winning line LN is activated when a specified number of bets according to the gaming state are set.

  In this embodiment, when all the reels 2L, 2C, and 2R are stopped, the activated pay line is activated (in the present embodiment, all the pay lines are always activated. When a combination of symbols called “combinations” is arranged on the activated winning line (simply called the winning line), a winning is achieved. 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 to a game state advantageous to the player. Below, a small role and a re-playing role are collectively called a general role. In order for winning of each combination determined according to the gaming state to occur, it is necessary to win an internal lottery to be described later and set a winning flag of the combination in the RAM 41c. Of these winning flags, the winning flags for the small role and the replaying role are valid only in the game in which the flag is set, and are invalid in the next game. It is valid until a combination of combinations permitted by the flag is completed, and is invalid in a game having a combination of combinations permitted. In other words, once the special combination winning flag is won, even if the combination of the combinations permitted by the flag cannot be made, 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, whether or not the main control unit 41 allows the winning of each combination described above before the display results of all the reels 2L, 2C, and 2R are derived (specifically, the start switch 7 At the time of detection). 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 generated by the random number circuit 508b and stored in the random number value register of the random number circuit 508b is set as the lottery work assigned to the RAM 41c. And, for each combination determined according to the gaming state, according to the numerical data stored in the lottery work and the number of determination values of each combination determined according to the current gaming state, the number of bets and the set value A determination is made as to whether or not winning is permitted.

  In the internal lottery, the number of judgment values determined in accordance with the internal lottery target, the current gaming state, and the set value are sequentially assigned to the random number for internal lottery (numerical data stored in the 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 combination determined to be winning is set in the internal winning flag storing work assigned to the RAM 41c. The internal winning flag storage work consists of a 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 table creation data stored in the ROM 41b when the reel starts to rotate 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. The stop control table is data that can specify the number of sliding frames for each timing when the stop operation is performed. 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 present 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 the present embodiment, when any of the winning combinations is won, when the stopping operation is performed, the winning combination is stopped on the winning line in the drawing range of up to 4 frames. If it is possible, control is performed to align and stop, and the winning combination that has not been won is controlled to be stopped without being aligned in the 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 maximum on the winning line when the stop operation is performed If it is possible to align and stop the winning roles in the 4-frame pull-in range, control will be performed to align them and stop them, and the winning roles will be selected on the winning line within the maximum 4-frame pull-in range. If it is not possible to withdraw, if a special role that has been elected within the draw range of up to 4 frames can be aligned and stopped on the winning line, it will be controlled and stopped. Control to stop without aligning in the drawing range of 4 frames will be performed. 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. In the case where a special combination and a small combination can be withdrawn at the same time, only the small combination is drawn, and the small combination is not aligned on the winning line at the same time as the special combination. Also, when a special role and a small role are elected at the same time, priority is given to the control of aligning the special role on the winning line over the small role, and only when the special role cannot be drawn, the small role is placed on the winning line. You may perform control to align.

  Also, in this embodiment, when the special role and the replaying role are won at the same time, such as when the replaying role is won while the special role has been carried over from before the previous game, the stop operation is performed. At the time of quitting, control is performed so that the symbols of the re-gamer are aligned and stopped on the winning line with 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, the reel stop control is performed by using a stop control table that can specify the number of sliding frames for each timing at which the stop operation is performed. A configuration that performs stop control by specifying a stop position from the position table and stopping the reel at the specified stop position, and searching for a stop position that can be stopped at a stop operation timing without using the stop control table or the stop position table・ Specifically configured to perform stop control to stop the reel at the specified stop position, stop control using the stop control table, stop control using the stop position table, and stop without using the stop control table or stop position table Configuration that uses stop control by searching and specifying the correct stop position, and configuration that performs stop control by partially changing the stop control table and stop position table It may be.

  In the present embodiment, the main control unit 41 counts the game time, which is the time that has elapsed since the start of reel rotation, every time the reel starts rotating after the game starts. After a game is over, when a specified number of bets are set by inserting medals, etc., and the game start operation is enabled, the reel rotation of the previous game is performed. If the game time that started timing from the start time is longer than the specified time (4.1 seconds in this embodiment), that is, if the specified time has elapsed since the start of reel rotation of the previous game, a wait is generated. At that time, the rotation of the reel for the game in the game is started. On the other hand, after the end of one game, when a predetermined number of bets are set by inserting medals, etc., and when the game start operation is enabled, the reel rotation of the previous game is started. If the game time that started timing from the time is less than the specified time, that is, if the specified time has not elapsed since the start of reel rotation of the previous game, a wait is generated and the reel starts rotating at that time. First, it waits until the game time that has started timing from the reel rotation start time of the previous game reaches the specified time, and starts rotating the reel when it reaches the specified time.

  In the present embodiment, the main control unit 41 performs control to output an external output signal indicating a gaming state, an error occurrence state, and the like. These external output signals are output to a hall device such as a hall computer via the information output terminal board of the game shop (hall) where the external output board 1000 and the slot machine 1 are installed.

  The main control unit 41 has a medal IN signal indicating the number of medals used for setting the number of bets, a medal OUT signal indicating the number of medals awarded to the player due to the occurrence of winning, and the gaming state is RB (regular bonus).

  The external output board 1000 is provided with a relay circuit, a parallel / serial conversion circuit, a terminal for each output signal, and a connector to be electrically connected to the circuit of the information providing terminal board. Of the signals output from the game control board 40, the medal IN signal, the medal OUT signal, the RB signal, and the BB signal are directly output as pulse signals to the information providing terminal board via the relay circuit. On the other hand, the door opening signal, setting change signal, input error signal, and payout error signal are converted into security signals, which are serial signals that can be individually identified by the parallel-serial conversion circuit, and information is provided. Output to the terminal board.

Or, when a prescribed number of bets is not set, a medal is inserted, or when the bet number is set by operating the MAXBET switch 6. The inserted number command is transmitted when the betting number setting operation is performed, so that it is possible to specify that the betting number setting operation has been performed by receiving the inserted number 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 game state command is a command that can specify the game state of the game, and is transmitted when the start switch 7 is operated to start the game. The internal winning command is a command that can specify the internal lottery result, and is transmitted when the start switch 7 is operated to start the game and after the gaming state command is transmitted. Since the game state command and the internal winning command are transmitted when the start switch 7 is operated and the game starts, it is possible to specify that the game is started by operating the start switch 7 by receiving these commands. It is.

  The reel acceleration information command is a command that can specify that the rotation of the reel starts with the progress of the game, and is transmitted when the rotation of the reel starts with the progress of the game. The stop operation command is a command that can specify whether the reel to be stopped is the left reel, the middle reel, or the right reel, and the area number of the stop operation position of the corresponding reel. Sent every time the accompanying stop control is performed. The sliding frame number command is a command that can specify whether the reel to be stopped is a left reel, a middle reel, or a right reel, and the number of sliding frames to be moved from when the corresponding reel is stopped until it stops. Each time stop control associated with the stop operation of each reel is performed, the corresponding stop operation command is transmitted after being transmitted. The stop command is a command that can specify whether the reel to be stopped is a left reel, a middle reel, or a right reel, and the area number of the stop position of the corresponding reel. Stop control associated with the stop operation of each reel Is transmitted after the corresponding sliding frame number command is transmitted. With the stop operation command, the sliding frame number command, and the stop command, it is possible to specify whether the reel to be stopped is the left reel, the middle reel, or the right reel, and accompanying the stop operation of each reel Since it is transmitted every time stop control is performed, by receiving these commands, it is possible to specify that one of the reels has been stopped and the reel to be stopped.

  The game end command is a command that can specify that the game has ended, and is transmitted when the player presses the stop switch to stop the third stop reel and releases the stop switch. The winning number command is a command that can specify a combination of symbols arranged on the winning line LN, whether or not a winning is received, a type of winning, and a payout number of medals at the time of winning. The player stops the third stop reel. This is when the stop switch is pressed and released, and is transmitted after the game end command is transmitted. Both the game end command and the winning number command are transmitted when the player depresses the stop switch to release the third stop reel and releases the stop switch. It is possible to specify that all operations necessary to advance one game have been completed.

  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 standby command is a command indicating a transition to the standby state, and when the transition to the standby state occurs after one game is over and the estimated end time (60 seconds in this embodiment) has elapsed without setting the bet amount, It is transmitted after the payout of medals by the settlement of credits (including medals used for setting the number of bets) is completed and a payout end command is transmitted.

  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). Sent before the setting can be started), and when the detection state of the door opening detection switch 25 changes (ON to OFF, OFF to ON). The operation detection command is a command indicating the detection state (ON / OFF) of the operation switches (MAXBET switch 6, start switch 7, stop switches 8L, 8C, 8R), and is transmitted at regular intervals.

  The counter value command is a command indicating various counter values such as an AT counter, an additional specialization zone counter, and a precursor effect counter that are updated in a state counter process described later.

  Of these commands, commands other than the door command and the operation detection command are generated in the basic process, temporarily stored in the command queue provided in the RAM 41c, and transmitted in the subsequent command transmission process of the timer interrupt process (main). The On the other hand, the door command is generated in the door monitoring process of the timer interrupt process (main), temporarily stored in the command queue provided in the RAM 41c, and transmitted in the subsequent command transmission process of the timer interrupt process (main). Is done. The operation detection command is generated based on the detection state of the switch every time the command transmission process of the timer interrupt process (main) is executed 10 times, and is temporarily stored in the command queue provided in the RAM 41c. Then, it is transmitted in the command transmission process of the subsequent timer interrupt process (main).

  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.

  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 55, 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.

  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.

  Next, various control contents executed by the main control unit 41 in the present embodiment will be described below with reference to FIGS.

  When the main control unit 41 is activated due to the occurrence of a reset, the main control unit 41 performs setting at the time of activation. In the startup setting, a status flag included in the main control unit 41 is initialized. The status flag is data that holds the state of the operation result and execution result of the instruction, and particularly includes an interrupt master permission flag for setting interrupt prohibition / permission. Since the initial value of the interrupt master permission flag is a value indicating prohibition of interrupt, the main control unit 41 is started in a state where interrupt is prohibited.

  After that, the main control unit 41 sets various functions with reference to the HW parameters, and then performs an initial setting process shown in the flowchart of FIG. 7 according to the program stored in the program / data area. In the initial setting process, interrupts are first prohibited by setting the value of the interrupt master permission flag to a value indicating that interrupts are prohibited (Sa1). As described above, the main control unit 41 is started in an interrupt-inhibited state, but in Sa1, the interrupt is again prohibited. Next, initialization data is set (Sa2), and each output port is initialized (Sa3). Next, the built-in register is set (Sa4).

  Next, it is determined whether or not the power supply voltage is normal (Sa5). If the power supply voltage is not normal, the determination is repeated until normal. If the power supply voltage is normal, the upper address of the interrupt vector is set (Sa6). Then, access to the RAM 41c is permitted (Sa7), and the stack pointer is initialized (Sa8).

  Next, the RAM parity is calculated (Sa9). Then, it is determined whether or not the calculated RAM parity becomes 0 (Sa10). If the RAM parity does not become 0, the process proceeds to step Sa13 to clear the destruction diagnosis data (Sa13).

  When the RAM parity becomes 0, destruction diagnosis data is acquired from the RAM 41c (Sa11). Then, it is determined whether or not the acquired destruction diagnosis data is correct (Sa12), and the destruction diagnosis data is cleared (Sa13).

  Next, it is determined whether or not the setting key switch 37 is in an ON state (Sa14). When the setting key switch 37 is in the ON state, a timer interrupt is set (Sa19). Specifically, the register of the timer circuit 509 built in the main control unit 41 is set so that a timer interrupt is periodically taken every predetermined time. In this embodiment, a value corresponding to about 0.56 ms is set in a predetermined register (time constant register), so that a timer interrupt is periodically generated about every 0.56 ms. In the timer circuit 509, the register is set, so that the timer is initialized and starts counting from the initial value. When the timer interrupt setting in step Sa19 is completed, the process proceeds to a setting change process.

  On the other hand, when the setting key switch 37 is in the OFF state, it is determined whether or not the stored contents of the RAM 41c are destroyed (Sa15). In step Sa15, it is determined whether a RAM abnormality flag, which will be described later, is set, and whether the storage content of the RAM 41c is destroyed based on the determinations in Sa10 and Sa12. If the stored contents of the RAM 41c are not destroyed, a return command is transmitted to the sub-control unit 91 (Sa16). In the case where the stored contents of the RAM 41c are not destroyed, it is determined that the RAM abnormality flag is not set and the RAM parity is 0 in the step Sa10, and further, the destruction diagnosis data is obtained in the step Sa12. This is the case when it is determined to be correct.

  After the step Sa16, all the registers are restored (Sa17), and the timer interrupt setting similar to the step Sa19 is performed (Sa18). Then, the process proceeds to Sd24 in a timer interrupt process (main) described later. As a result, the process that was being executed before the power interruption is restored.

  If the stored contents of the RAM 41c are destroyed in the step of Sa15, the RAM start address (0000h) is set in the register (Sa20), and the address from the specified address to the last usable address (0FFFh) is set. The area, that is, the entire usable area is initialized (Sa21).

  Next, a RAM abnormality flag indicating that the storage content of the RAM 41c is not normal is set in the RAM 41c (Sa22), and the process proceeds to error processing. In error processing, the progress of the game is disabled. Further, the error state that has been shifted after the RAM abnormality flag is set can be canceled by shifting to the setting change process by setting the setting key switch 37 to ON and turning on the power switch 39. On the other hand, when the power switch 39 is turned on without turning the setting key switch 37 on, the RAM abnormality flag remains set, and an error state occurs again.

  Next, the setting change process which the main control part 41 performs is demonstrated.

  As shown in FIG. 8, the main control unit 41 first sets a RAM start address (0000h) in a register (Sb1). Next, it is determined whether or not the stored contents of the RAM 41c are destroyed in the same manner as in the step Sa15 shown in FIG. 7 (Sb2). If the contents of the RAM are not destroyed, that is, if the contents of the RAM are not abnormal, the start address of the initialization target RAM at the start of setting change is set in the register (Sb3). That is, the address set in Sb1 is changed. If the contents of the RAM are destroyed, that is, if the contents of the RAM are abnormal, the process proceeds to step Sb4.

  Next, the area from the address designated in the step Sb1 or Sb3 to the last address of the usable area is initialized (Sb4). In step Sb1, the start address of the RAM is set. In this case, all the usable areas are initialized in step Sb4. On the other hand, since the start address of the initialization target RAM at the start of setting change is set in the step Sb3, in this case, in the step Sb4, areas other than the important work and the special work are initialized among the usable areas. Will be.

  Next, a setting command indicating the start of the setting change state is transmitted to the sub-control unit 91 (Sb5), and interruption is permitted (Sb6).

  Next, it is determined whether or not the reset / setting switch 38 has changed from OFF to ON (Sb7). When the reset / setting switch 38 changes from OFF to ON, the set value of the register is updated (in the case of 1 to 5, 1 is added, and in the case of 6, it is updated to 1) (Sb8). If the reset / setting switch 38 has not changed, it is determined whether or not the start switch 7 has changed from OFF to ON (Sb9).

  If the start switch 7 has not changed, the process returns to step Sb7. When the start switch 7 is changed from OFF to ON, it is determined whether or not the setting key switch 37 is in the OFF state (Sb10). If the setting key switch 37 is not in the OFF state, the determination is repeated until the setting key switch 37 is in the OFF state. If the setting key switch 37 is OFF, the setting value data set in the register is stored in the RAM 41c (Sb11).

  Next, a setting command indicating the end of the setting change state is transmitted to the sub-control unit 91 (Sb12). Then, the initial address of the initialization target RAM at the end of the setting change is set in the register (Sb13), and the process proceeds to the main process.

  Next, main processing executed by the main control unit 41 will be described. The main process is repeatedly executed for each unit of game. One period of the main process corresponds to one unit of the game.

  As shown in FIG. 9, the main control unit 41 first prohibits an interrupt (Sc1). Next, the final address of the initialization target RAM is set (Sc2).

  Next, the RAM area indicated by the designated address is cleared (Sc3). At this time, if the main process is started after the setting change process, the initial address of the initialization target RAM at the end of the setting change is set. In the step Sc2, the final address of the initialization target RAM at the end of the setting change ( 0FFFh) is set, the area other than the important work and the special work among the usable areas is initialized. Also, at the end of the game that is not at the end of the specific game state, the initial address of the initialization target RAM at the end of the specific game state is set at the step of Sc10 described later, and at the step of Sc2, the stack is set as the final address. Since the address indicated by the pointer is set, the general work, the unused area, and the unused stack area among the available areas are initialized. Also, at the end of a specific gaming state and at the end of the game, the start address of the initialization target RAM at the end of the game is set in the later-described Sc11 step, and in the Sc2 step, the stack pointer is used as the final address. Therefore, the unused area and the unused stack area are initialized among the usable areas.

  After initialization of the RAM in the step of Sc3, interrupts are permitted (Sc4).

  Next, a game start waiting process is executed (Sc5). In the game start waiting process, the process waits in a state where a bet number can be set, and a process for starting a game is executed when a specified number of bets are set according to the game state and the start switch 7 is operated.

  Next, an internal lottery process is executed (Sc6a). In the internal lottery process, whether or not to win the above-mentioned winning combination based on the internal lottery random value latched simultaneously with the start of the game by the detection of the start switch 7 in the step of Sc5 (that is, the display result is derived). The process of determining whether or not to allow) is performed. Further, in the internal lottery process, a lottery process for determining whether or not the transition to the AT (assist time) state is allowed is performed. In the AT state, until the number of AT games becomes zero, an effect is specified that specifies an operation procedure (push order) for stopping a symbol combination advantageous to the player on the winning line LN (advantageous to the player). A game state in which advantageous control is performed) and a state advantageous for the player (advantageous state). As a result, in the AT state, symbol combinations that are advantageous to the player can be arranged on the winning line, which is advantageous to the player.

  Further, in the internal lottery process, when a lottery that allows the transition to the AT state is won, a lottery for the initial number of AT games is performed. Further, in the internal lottery process, when the game state is the added special zone state, the number of AT games is added and drawn.

  Next, state counter processing is executed (Sc6b). In the state counter process, various counter update processes relating to the gaming state transition of the slot machine 1 are performed. Details of the state counter process will be described later.

  Next, a reel control process is executed (Sc7). In the reel control process, the process of rotating each reel 2L, 2C, 2R in response to the operation of the start switch 7, the result of the internal lottery in the step of Sd2, and the operation of the stop switch 8L, 8C, 8R by the player are detected. In response to this, processing for stopping the rotation of the corresponding reels 2L, 2C, 2R is executed.

  Next, a game end time setting process is executed (Sc8). In the game end setting process, when it is determined that the rotation of all the reels 2L, 2C, and 2R is stopped in the process of Sc7, a winning occurs according to the display result derived for each reel 2L, 2C, and 2R. The process which determines whether or not is executed.

  In the game end setting process, a state control process for setting the gaming state of the slot machine 1 is performed based on the values of various counters updated in Sc6b. Details of the state control process will be described later.

  Further, in the game end setting process, when it is determined that a winning has occurred, processing such as addition of credits and paying out medals is performed based on the number of payouts according to the winning. When a winning occurs, a process for setting a gaming state for the next game is executed after the medal payout is completed. Further, when no winning occurs, after the reels are stopped, processing for setting a gaming state for the next game is executed.

  When the setting process at the end of the game is completed, it is determined whether or not it is the end of the specific gaming state (Sc9). If it is not the end of the specific gaming state, the initial address of the initialization target RAM at the end of the game is determined. Set (Sc10) and return to the step of Sc1. If it is at the end of the specific gaming state, the start address of the initialization target RAM at the end of the specific gaming state is set (Sc11), and the process returns to the step of Sc1.

  In the main process, a command is generated in accordance with the progress of the game, set in the command buffer, and transmitted to the sub-control unit 91 in the subsequent timer interrupt process (main). The sub control unit 91 performs various processes based on commands from the main control unit 41.

  FIGS. 10 and 11 are flowcharts showing the control contents of the timer interrupt process (main) executed by the main control unit 41 by interrupting and executing the basic process (mainly the main process) at a constant interval (approximately 0.56 ms). is there. The timer interrupt process (main) is a process executed by an interrupt generated according to the count of the timer circuit 509. The address at which the program of the timer interrupt process (main) is stored is a vector table. It is set as a value corresponding to the timer interrupt. When a timer interrupt occurs, processing from that address is executed. Further, other interrupts are automatically prohibited during the execution period of the timer interrupt process (main).

  As shown in FIG. 10, in the timer interrupt process (main), first, the register in use is saved in the stack area (Sd1).

  Next, a power failure determination process is performed (Sd2). In the power failure determination process, it is determined whether or not a voltage drop signal is input from the power failure detection circuit 48. If a voltage drop signal is input, whether or not the voltage drop signal is input in the previous power failure determination process as well. If a voltage drop signal has been input in the previous power failure determination process, it is determined that a power failure has occurred, and a power interruption flag indicating that is set.

  After the power failure determination process in step Sd2, it is determined whether or not the power interruption flag is set (Sd3). If the power interruption flag is not set, the process proceeds to Sd4 and the power interruption flag is set. In this case, the process proceeds to a power interruption process (main).

  In step Sd4, port input processing for inputting detection data of various switches from the input port is performed.

  Next, the branch counter for identifying the timer interrupt to be executed in the timer interrupt process (main) is advanced by 1 from the four types of timer interrupts 1 to 4 (Sd5). In step Sd5, 1 is added when the branch counter value is 0 to 2, and is updated to 0 when the counter value is 3. That is, the branch counter value loops in the order of 0 → 1 → 2 → 3 → 0... Each time the timer interrupt process (main) is executed.

  Next, the branch counter value is referenced to determine whether it is 2 or 3, that is, timer interrupt 3 or timer interrupt 4 (Sd6). If it is not timer interrupt 3 or timer interrupt 4, that is, timer interrupt In the case of 1 or timer interrupt 2, motor phase signal output processing for outputting the phase signal data of the reel motors 32C, 32C, 32R is executed (Sd7).

  Next, referring to the counter value for branching, it is determined whether or not it is 1, that is, timer interrupt 2 (Sd8). If it is not timer interrupt 2, that is, timer interrupt 1, the reel motor Reel start processing (Sd9) for controlling the step time interval when starting 32L, 32C, 32R, motor step processing (Sd10) for changing phase signal data of the reel motors 32L, 32C, 32R, reel motors 32L, 32C After the stop of 32R, motor phase signal standby processing (Sd11) for changing the phase signal to one-phase excitation after a lapse of a certain time is sequentially executed, and then the process proceeds to step Sd24.

  In the case of timer interrupt 2 in step Sd8, LED dynamic display processing for dynamically lighting various indicators (Sd12), control signal output processing for outputting data such as lighting signals of various LEDs to the output port, etc. (Sd13), a time counter update process for updating various time counters (Sd14), a door monitoring process for monitoring the detection state of the door open detection switch 25, a door command transmission request (Sd15), and the command buffer. After sequentially executing a command transmission process (Sd16) for transmitting various commands to the sub-control unit 91 and an external output signal update process (Sd17) for updating an external output signal, the process proceeds to step Sd24.

  If it is timer interrupt 3 or timer interrupt 4 in step Sd6, it is further determined by referring to the branch counter value whether it is 3 or not, ie, timer interrupt 4 (Sd18). If interrupt 4 is not interrupted, that is, if timer interrupt 3 is detected, the origin passing process (Sd19) for checking the origin passing (passing of the reel reference position) of the rotating reels 2L, 2C, 2R is detected, and switches are detected. After sequentially executing the switch input determination process (Sd20) for determining whether or not the state has changed, the process proceeds to step Sd24.

  If the timer interrupt is 4 in the step of Sd18, stop switch processing (Sd21) for determining the stop position in accordance with detection of the stop switches 8L, 8C, 8R. After the stop process (Sd22) to be started and the final stop process (Sd23) in which the three-phase excitation is performed after a certain time from the start of the brake in the stop process, the process proceeds to step Sd24.

  In step Sd24, the register saved in the stack area in Sd1 is restored, and the process returns to the state before the interrupt.

  FIG. 12 is a flowchart showing the control content of the power interruption process (main) executed when the main control unit 41 determines that the power interruption flag is set in the timer interrupt process (main) described above.

  In the power interruption process (main), first, all registers that may be in use are saved in the stack area (Se1). Although the values of the I register and IY register described above are used, they are not saved here because the same fixed value is always set with the initialization at the time of startup.

  Next, destruction diagnosis data (5A (H) in the present embodiment) is set (Se2). Then, all output ports are initialized (Se3). Next, RAM parity adjustment data is calculated and set so that the exclusive OR of all storage areas (including unused areas and unused stack areas) of the RAM 41c is 0 (Se4), and access to the RAM 41c is performed. It is prohibited (Se5).

  Thereafter, the voltage decreases, and the CPU 41a of the main control unit 41 stops and shifts to a standby state. And if a voltage falls in this standby state, it will be in an operation stop state internally. Therefore, the main control unit 41 reliably stops operation when power is interrupted.

  As described above, in the present embodiment, the main control unit 41 starts in an interrupt-disabled state when a reset occurs, and then interrupts the program at the start of the initial setting process to be executed first. It is possible to prevent an unintended interrupt from occurring even when the main control unit 41 is activated in a state where the interrupt is not prohibited for some reason.

  In addition, the main control unit 41 is configured to permit the interrupt after setting the timer interrupt in the timer circuit 509 after the activation, and the interrupt is generated in a state where the timer interrupt does not operate normally. Can be prevented. In the timer circuit 509, the timer is initialized by setting the timer interrupt, and the timer starts counting from the initial value. After starting, the time until the first interrupt occurs Timer interrupts can be generated at regular time intervals without any deviation from the time until the second and subsequent interrupts are generated. In addition, the main control unit 41 is configured to update the setting of the timer circuit 509 to the initial value by a program in the initial setting process, and when the setting of the timer circuit 509 is rewritten for some reason at the time of activation. Even if it exists, it can prevent that the unintended interruption generate | occur | produces.

  Further, the main control unit 41 proceeds to the setting change process if the setting key switch 37 is in an ON state at the time of activation, and initializes the RAM 41c at the start of the setting change process. At this time, if the data in the RAM 41c is normal, the important work and the special work are held and the other areas are initialized so that the control state (setting value, gaming state, etc.) before the change is changed after the setting is changed. While some data can be retained, if the data in the RAM 41c is not normal, all the usable areas including the important work and the special work are initialized to ensure that the data in the RAM 41c is abnormal. Can be resolved.

  In addition, since the RAM abnormality flag is set when the RAM abnormality is determined, the main control unit 41 is turned off after the occurrence of the RAM abnormality error, and the RAM parity is 0 when the power is turned on again. Yes, even if it is determined that the destruction diagnosis data is normal, it is possible to determine whether the data in the RAM 41c is destroyed based on the RAM abnormality flag.

  Moreover, the main control part 41 performs the main process which processes in steps according to progress of a game for every game unit after completion | finish of a setting change process. In the main process, the RAM 41c is initialized for each game unit, and the RAM 41c is also initialized at the end of the setting change process. After the setting change process, the main process starts from the stage before the process of initializing the RAM 41c in the main process. The initialization of the RAM 41c after the setting change process is completed and the game unit It is possible to perform initialization of the RAM 41c for each process by common processing.

  Further, when the RAM 41c is initialized, the main control unit 41 prohibits interrupts until the initialization is completed, and the timer interrupt process (main) is performed during the initialization of the RAM 41c. Occurrence can prevent the initialized contents from being changed and the processing performed in the timer interrupt processing (main) from being performed normally.

  Further, the main control unit 41 updates the output state of the external output signal in the main process, and changes the output state of the external output signal in the subsequent timer interrupt process (main) based on the updated output state. In addition, when updating the output state of the external output signal, interrupts are prohibited until the update is completed, and timer interrupt processing (main) occurs before the output state of the external output signal is completed By doing so, it is possible to prevent an external output signal indicating unintended data from being output.

  Next, a timer counter for measuring a time interval used by the main control unit 41 for game progress control and the like will be described.

  The main control unit 41 sets an initial value corresponding to the measured time as the timer value of the timer counter assigned to the RAM 41c when the time measurement start condition is satisfied, and periodically sets a timer in the timer interrupt process (main). The value is subtracted, and when the timer value becomes 0, it is specified that the time has elapsed.

  Specifically, when a timing start condition is established in the main process, the main control unit 41 sets an initial value of a timer value corresponding to the timing time in an area to which a timer counter corresponding to the condition is assigned.

  The set timer value is decremented by 1 until it becomes 0 every 2.24 ms in the time counter update process of the timer interrupt process (main).

  In the main process, as shown in FIG. 13, the address of the corresponding timer counter is acquired (Sf1), the acquired value is read (Sf2), and it is determined whether or not the read value is 0 (Sf3). If it is determined that the read value is 0, it is determined that the time has elapsed.

  As shown in FIG. 14, the timer counter used in the present embodiment has a 1-byte timer A whose initial value is 1 byte or less, 1-byte timer B, 1-byte timer C, an initial value exceeding 1 byte, and 2 bytes or less. 2 byte timer A, 2 byte timer B, 2 byte timer C, and 2 byte timer D.

  The 1-byte timer is a timer for measuring a relatively short period that can be measured with a timer value within 1 byte. For example, an external output signal timer that measures an output period of an external output signal, an LED output update period LED update timer that measures the time, stop invalid timer that measures the period until the stop operation is validated after detection of the stop operation, wait for payout that measures the period until the medal payout starts after the reel stops Timer, insertion detection timer for measuring the period after the insertion medal sensor 31 is detected ON, insertion slot detection timer for measuring the period after the detection of the insertion slot sensor 26 is detected, and ON of the dispensing sensor 34c are detected There are a payout detection timer for measuring a period after being started, a start-up timer for measuring a period from the start of reel rotation until the stop operation becomes effective. Among these, the stop invalid timer, the payout waiting timer, and the start timer do not cross the timing at which one game ends, but the external output signal timer, the LED update timer, the input detection timer, the input port The detection timer and the payout detection timer may straddle the timing at which one game ends with the time measured by these timers.

  The 2-byte timer is a timer for measuring a relatively long period that cannot be measured with a timer value within 1 byte. For example, a 1-game time timer that measures a specified time (about 4.1 seconds) required for 1 game. , A security signal timer for measuring the minimum output period of the security signal among the external output signals, a standby time timer for measuring a period from the end of the game, and a hopper empty for measuring a period in which the payout sensor 34c is not detected after the hopper motor 34b is driven. There is a timer. Of these, the waiting time timer and the hopper empty timer do not straddle the timing when one game ends, but the one gaming time timer and the security signal timer have one measuring time measured by these timers. There are times when the timing of the end of.

  As described above, the timer counter is a timing at which one game ends, that is, a timing at which a part of the RAM 41c is initialized as the game progresses (a part of the RAM 41c at the end of one game or at the end of a specific gaming state). Including a timer counter that measures a measurement period spanning the timing at which a part of the RAM 41c is initialized in accordance with the progress of the game. The counter is also assigned to a special work that is not initialized at the timing according to the progress of the game.

  Among these timer counters, the 1-byte timers A to C are allocated 1 byte at a time to the continuous 3-byte area (7E2Ch to 7E2Eh) of the RAM 41c, and the 2-byte timers A to D are the continuous 8-byte RAM 41c. Two bytes are allocated to the area (7E2Fh to 7E35h). Further, the 1-byte timers A to C and the 2-byte timers A to D are also assigned to continuous areas of the RAM 41c. Hereinafter, an area to which the 1-byte timers A to C are allocated is referred to as a 1-byte timer group, and an area to which the 2-byte timers A to D are allocated is referred to as a 2-byte timer group. That is, both the 1-byte timer group and the 2-byte timer group are set in an area to which consecutive addresses are assigned according to a predetermined rule. The area to which consecutive addresses are assigned according to a predetermined rule is, for example, an area to which an address added by N (N is a natural number) from the start address and the start address is assigned.

  FIG. 15 is a flowchart showing the control content of the time counter update process.

  In the time counter update process, first, the number of 1-byte timer counters to be updated (3 in the present embodiment) is set as the number of processes for 1 byte (Sg1), and the first address of the 1-byte timer group (7E2Ch) A pointer is set to (Sg2).

  Next, if the value of 1 byte stored at the specified address (address indicated by the pointer) is not 0, 1 is subtracted from the value of 1 byte of the specified address (Sg3), and 1 is subtracted from the processing count set in the step of Sg1. (Sg4), it is determined whether the number of processes after subtraction is 0 (Sg5).

  If the number of processes after subtraction is not 0 in the step of Sg5, that is, if all the 1-byte timers have not been updated, the pointer is incremented by 1 (Sg6), and the process returns to the step of Sg3. As a result, the pointer moves to the address of the unprocessed 1-byte timer, and if the 1-byte value of the designated address is not 0, the pointer is subtracted.

  When the number of processes after subtraction is 0 in the step of Sg5, that is, when all 1-byte timers have been updated, the number of 2-byte timer counters to be updated (this embodiment) In the embodiment, 4) is set (Sg7), and the pointer is incremented by 1 (Sg8). As a result, the pointer moves to the start address (7E2Fh) of the 2-byte counter group.

  Next, if the 2-byte value stored in the area consisting of the designated address (address indicated by the pointer) and the next address is not 0, the 2-byte value of the designated address and the next address is decremented by 1 (Sg9), and Sg7 1 is subtracted from the number of processes set in step (Sg10), and it is determined whether or not the number of processes after subtraction is 0 (Sg11).

  If the number of processes after the subtraction is not 0 in the step of Sg11, that is, if all the 2-byte timers have not been updated, the pointer is incremented by 2 (Sg12), and the process returns to the step of Sg9. As a result, the pointer moves to the address of the unprocessed 2-byte timer, and if the 2-byte value of the designated address and the next address is not 0, the pointer is subtracted.

  If the number of processes after subtraction is 0 in the step of Sg11, that is, if all the 2-byte timers have been updated, the process ends.

  As described above, in the present embodiment, the value of the timer counter assigned to the RAM 41c is periodically updated to become a specific value (0), thereby specifying the passage of time. Conventionally, when measuring multiple types of time intervals, timer values are set and updated within multiple types of processing that require timekeeping, and each type of program for updating multiple types of timer values is processed. Since it is necessary to provide it inside, it was a factor which increased program capacity. In addition, since multiple types of timer counters are assigned as data groups for each process used, it is necessary to read out the values of unrelated addresses in order to update all of them in one process. there were.

  On the other hand, in the present embodiment, an area in which a plurality of types of timer counter values are stored is set to an area to which consecutive addresses are assigned according to a predetermined rule in the RAM 41c, and the timer value stored in the designated address is set. Updates multiple types of timer values by repeatedly executing the process of updating the specified address for the area where multiple types of timer counter values are stored by adding a constant to the current specified address As a result, the program capacity can be reduced as compared with the case where each of the processes for designating a plurality of types of addresses and updating the values of the addresses is performed in each process.

  Multiple types of timers can be obtained by repeatedly executing the process of updating the timer value stored at the specified address while changing the specified address for the area where the multiple types of timer counter values are stored by performing a predetermined calculation. Any configuration may be used as long as the value is updated. For example, by adding a constant to the current designated address, multiple types can be obtained by repeatedly executing while changing the designated address for an area in which multiple types of timer counter values are stored. The timer value may be updated, or a value corresponding to the number of processes with respect to the reference address (for example, for a 1-byte counter, +1 for the number of processes 1, +1 for the number of processes 2, and the number of processes While changing the designated address for the area where multiple types of timer counter values are stored by adding or subtracting +3 ...) for 3 Ri may be configured to update a plurality of types of the timer value by return run.

  In the present embodiment, the configuration includes seven types of timer counter values of 1-byte timers A to C and 2-byte timers A to D. However, at least two types of timer counter values are stored in the RAM 41c according to a predetermined value. The specified address for the area where multiple types of timer values are stored is changed by performing a predetermined operation on the process of updating the timer value stored in the specified address by setting the area where consecutive addresses are assigned by the rule. However, if the configuration is such that two or more types of timer values are updated by repeated execution, the program capacity can be reduced as described above.

  In addition, only one of the 1-byte timer and 2-byte timer is set to set the timer counter value in an area to which consecutive addresses are assigned according to a predetermined rule in the RAM 41c, and update the timer value stored in the designated address. A configuration in which a plurality of types of timer values are updated by repeatedly executing a predetermined calculation while changing a designated address for an area in which a plurality of types of timer values are stored may be employed.

  Further, only for some of the timer counters provided in the main control unit 41, a process of setting a timer value in an area to which consecutive addresses are assigned according to a predetermined rule in the RAM 41c and updating the timer value stored in the designated address, A configuration in which a plurality of types of timer values are updated by repeatedly executing a predetermined calculation while changing a designated address for an area in which a plurality of types of timer values are stored may be employed.

  In the present embodiment, a separate timer counter is provided for each type of period to be measured. For example, a single timer counter may be shared for a plurality of types of periods in which the periods to be measured do not overlap. .

  In the present embodiment, the main control unit 41 executes a timer interrupt process (main) that periodically performs a predetermined process regardless of the game progress status, and a game progress status. The main control unit 41 sets an initial value in the timer counter when a time measurement condition is satisfied in the main process, and sets a plurality of types in the timer interrupt process (main). Since there is no need to provide multiple types of timer value update processing within each process that constitutes the main process, the program capacity for updating multiple types of timer values is reduced. can do.

  In this embodiment, the main process is periodically interrupted and the timer interrupt process (main) is executed. However, in the timer interrupt process that is periodically performed, the progress is made in advance regardless of the progress of the game. It is good also as a structure which performs both the regular process which performs a predetermined process, and the main process which performs a process which changes in steps according to the progress of a game, and also in such a structure, the main control part 41 is By setting the timer counter to an initial value when the timekeeping condition is met in the main process and updating multiple types of timer values in the periodic process, multiple types of timer values are included in each process that constitutes the main process. Since it is not necessary to provide a process for updating the program, it is possible to reduce the program capacity related to the update of a plurality of types of timer values.

  In the present embodiment, in the time counter update process, the value of the address is updated on condition that the value of the designated address is not 0, and the timer value is updated to an abnormal value. Can be prevented.

  In the present embodiment, in the time counter update process, the number of processes equal to the number of timer counters to be updated is set, and the process for updating the timer value is repeatedly executed for the set number of processes. Management of the number of timer counters to be updated is facilitated. For example, when a plurality of types of timer counters having different update intervals are provided, the type of timer value to be updated can be arbitrarily set according to the number of processes to be set. Can do.

  Note that the number of processes, that is, the number of timer counters to be updated may be set in a program, or values set in a table may be read and set.

  In addition, the timer counter to be updated last is set in advance without setting the number of processes at the beginning, and the timer value is updated repeatedly until the address of the timer counter is reached. It is also possible to store a specific end value (for example, FFh) at the next address of the timer counter, and to repeatedly execute the process of updating the timer value until the value read from the specified address becomes the specific end value. good.

  In the present embodiment, a 1-byte timer counter and a 2-byte timer counter are provided, and a process for updating a 1-byte timer value and a process for updating a 2-byte timer value are separately performed. Therefore, the capacity of the program and the capacity occupied by the timer value in the RAM 41c can be reduced as compared with the case where the process of updating the 1-byte timer value and the process of updating the 2-byte timer value are made common. .

  In the present embodiment, a 2-byte timer counter is provided to measure a relatively long time corresponding to an initial value exceeding 1 byte. For example, timer counters having different update intervals, for example, Timer interrupt processing (main) By providing a first timer counter that is updated once every four times and a second timer counter that is updated once every fourteen times, a relative value can be obtained without providing a 2-byte counter. It is also possible to measure a long time interval. In this way, it is not necessary to provide a process for updating a 1-byte timer value and a process for updating a 2-byte timer value. It is possible to reduce the program capacity related to the value update.

  In the present embodiment, a plurality of types of timer counters are assigned to special works that are not initialized in accordance with the progress of the game in the RAM 41c, and are not initialized in accordance with the progress of the game. Therefore, regardless of the progress of the game, it is possible to measure the time spanning the timing when a part of the RAM 41c is initialized according to the progress of the game.

  In particular, in the present embodiment, the measurement period is not only a timer counter that may cross the timing when one game ends, that is, the timing at which a part of the RAM 41c is initialized according to the progress of the game. Since the timer counter that does not cross over the timing at which a part of the RAM 41c is initialized as it progresses is stored in the area assigned to the special work together with other timer counters, the timer counter can be easily managed. In addition, a timer counter that does not cross the timing at which a part of the RAM 41c is initialized according to the progress of the game is used, and a timing at which a part of the RAM 41c is initialized according to the progress of the game. Easy to use the timer counter by changing the design later, such as changing to a timer counter that may straddle It can be changed. In addition, as described above, if a single timer counter is shared for a plurality of types of periods in which measurement periods do not overlap, the timing at which a part of the RAM 41c is initialized may be crossed as the game progresses. It is possible to measure the measurement period and the measurement period that does not cross the timing at which a part of the RAM 41c is initialized in accordance with the progress of the game with one timer counter.

[Special period]
Next, the special period will be described. In the present embodiment, when a rare role such as strong bell, strong watermelon, strong cherry, etc. is won during the AT game, it is added to the special zone with a predetermined ratio. The additional specialization zone is a period in which an additional number of AT games can be expected. In addition, when the bonus special zone is won, the bonus special zone is executed to perform the warning effect that suggests the start of the bonus special zone, and the start of the bonus special zone is notified after the warning effect is finished. The presence notification effect is executed. After that, the AT game is interrupted once and added to start the specialized zone.

  Therefore, in the present embodiment, the special period, which is the period from winning the additional specialization zone to starting the additional specialization zone, includes the number of games of the prelude effect and the number of games of the specialization zone presence notification effect. The number of games added.

  The effect form of the sign effect in the present embodiment is an effect aspect that changes the appearance of the effect screen. FIGS. 17B, 17C, 18B, 18C, and 18D, which will be described later, are diagrams showing a presentation aspect of a prelude effect in the present embodiment. In the example shown in the figure, the number of remaining games of the sign effect is displayed at the center of the effect screen in the sign effect. Thereby, the player can recognize that the sign effect has started by displaying the number of remaining games of the sign effect in the center of the effect screen. In addition, by confirming the number of remaining games of the sign effect displayed in the center of the effect screen, the player can recognize the number of continuing games of the sign effect. In the present embodiment, when the AT state is ended, the sign effect and the additional special zone notification effect are also ended, so the number of remaining games of the sign effect displayed on the effect screen of the sign effect is the actual sign effect. The remaining number of games may be different.

  Further, in the present embodiment, the precursor effect is executed by any of effects between 5 games, effects between 10 games, and effects between 20 games. Further, the extra special zone notification effect is executed in one game. Therefore, the special period (the number of precursor effect games + the number of notification effect games with additional special zones) is any of 6 games, 11 games, or 21 games. The distribution of the number of games for the sign effect will be described later. In the present embodiment, the additional specialization zone is between 5 games. In addition, when the added special zone ends, the AT game is resumed.

  FIG. 16 is a diagram showing the relationship between the special period and the number of AT remaining games in the present embodiment. FIG. 16A shows the special period and the number of AT remaining games in the case where the prelude effect is started when the special period (the number of predecessor effects + the number of games with the added special zone notification effect) is smaller than the number of AT remaining games. Shows the relationship. In the example shown in the figure, when the number of AT remaining games is 27 games, the rare role is won and the bonus special zone is won. Further, in the example shown in the figure, there are five sign effects, and the sign effects are performed when the number of AT remaining games is 26 to 22 games. Then, after the sign effect, when the number of AT remaining games is 21 games, the special zone presence notification effect is executed. In other words, the special period (the period from winning the extra special zone until starting the extra special zone) is between six games.

  In the example shown in the figure, after the special period, an additional special zone for five games is executed. In the example shown in the figure, 30 additional games corresponding to the number of AT games are won in the additional specialization zone. Therefore, the number of remaining AT games when the AT game is restarted after the additional specialization zone is finished is 50 games, which is obtained by adding the remaining 20 AT games before the execution of the additional specialization zone and 30 additional games. .

  In the case where the number of remaining AT games and the special period (the number of games of the sign effect + the number of games of the extra special zone notification effect) are the same, as in the example shown in FIG. An additional special zone presence notification effect, an additional special zone, and the restart of the AT game are performed.

  On the other hand, in the present embodiment, when the prelude effect is started when the special period (the number of predecessor effects + the number of games for the presence of specialization zone added) is greater than the number of AT remaining games, the number of AT remaining games is 0. It is determined that the special period has ended. As a result, the AT control is completed during the special period without checking the number of AT remaining games and setting a special period according to the number of AT remaining games (for example, a process of distributing the number of games of precursor effects). It will not happen. Therefore, the process can be simplified and the capacity of the program can be reduced. For example, since the storage capacity of the ROM 41b of the main control unit 41 is generally small, it is desirable to simplify the process and reduce the program data capacity when setting the length of the special period on the game control board 40. .

  FIG. 16B shows the special period and the number of AT remaining games in the case where the prelude effect is started when the special period (the number of predecessor effects + the number of games of the additional special zone notification effect) is larger than the number of AT remaining games. Shows the relationship. In the example shown in the figure, when the number of AT remaining games is 5, the rare role is won and the bonus special zone is won. In the example shown in the figure, the precursor effect is 5 games. For this reason, when the precursor effect and the added special zone notification effect are executed as in the prior art, the AT ends when the fifth effect of the precursor effect and the additional specialized zone notification effect is executed.

  Therefore, in the present embodiment, control is performed so that the special period ends when the AT ends. In the example shown in the figure, when the number of AT remaining games is 2, the number of remaining games of the warning effect is rewritten to 1, so that when the AT ends, a special period (the number of games of the warning effect + addition special zone notification effect) ) Is also controlled to end. In other words, by rewriting the value of the warning effect counter so that the number of remaining AT games and the number of games of the warning effect + addition special zone notification effect are the same, the special period ( The number of games of the warning effect + addition special zone notification effect) is also controlled to end.

  Further, in the example shown in the figure, after the special period ends, an additional special zone between five games is executed. Further, in the example shown in the figure, in the additional specialization zone, 30 additional AT games are won. Therefore, the number of AT remaining games when the AT game is resumed after the additional specialization zone is finished is 30 games obtained by adding the number of remaining AT games before the execution of the additional specialization zone and 30 additional games. .

FIG. 18D shows an example of an effect screen when one game has elapsed from FIG. 18C and a precursor effect is being executed. In the illustrated example, the number of remaining AT games is two. Therefore, in the present embodiment, as shown in the figure, when the number of AT remaining games is 2, by rewriting the number of remaining games of the precursor effect to 1, a special period (predictor effect + addition special zone) when the AT ends. The number of games of presence notification effect) is also controlled to end. In the example shown in the figure, the number of remaining games of the precursor game is one game, the number of remaining AT games is two games, the number of acquired games is 99, and the reels are stopped in the order of left reel, right reel, and middle reel. It is shown that.

FIG. 18 (E) shows an example of an effect screen when one game has elapsed from FIG. 18 (D) and an additional special zone notification effect is being executed. In the example shown in the figure, the number of AT remaining games is one game, and the number of acquired games is 105. This indicates that the middle reel, the right reel, and the left reel are stopped in this order, and that the player enters the specialization zone. . As described above, in the present embodiment, when the AT is finished, the special period (the number of games of the sign effect + the added special zone notification effect) is controlled to end.

  FIG. 18F shows an example of an effect screen in the specialization zone for addition. FIG. 18 (F) shows an example of an effect screen when one game has elapsed from FIG. 18 (E) and the additional specialization zone is being executed. In the example shown in the figure, the number of remaining games in the additional specialization zone is five games, and the number of acquired games is 111, which indicates that ten additional games have been won.

  FIG. 18G shows an example of an effect screen when the final game in the specialization zone for addition is completed. FIG. 18 (G) shows an example of an effect screen when five games have elapsed from FIG. 18 (F) and the final game in the additional specialization zone has ended. In the example shown in the drawing, the number of acquired sheets is 93, which indicates that a total of 30 games have been won in the additional specialization zone.

  FIG. 18H shows an example of an effect screen during an AT game. FIG. 18 (H) shows an example of an effect screen when the next game of FIG. 18 (G) is started and AT is resumed.

  In the present embodiment, a gasse sign effect is also executed. The effect form of the gasse sign effect is the same as the sign effect. However, in the present embodiment, when the gasse sign effect is finished, an additional special zone absence notification effect for notifying that the additional special zone is not started is executed, and then the game corresponding to the state is started. In other words, even if the gasse sign effect and the extra special zone absence notification effect are finished, the extra special zone is not started. In this way, since the prelude production and the gasse prelude production have the same production aspect, even if the prelude production is started, the player is caused to pay attention to whether or not the additional special zone is started. Can do.

  FIG. 19 shows an example of the effect screen when the gasse sign effect is started.

  FIG. 19A shows an example of an effect screen during an AT game. In the example shown in the figure, the number of AT remaining games is 4 and the number of acquired games is 85, which indicates that the middle reel, the left reel, and the right reel are stopped in this order.

  FIG. 19 (B) shows an example of an effect screen during the gasse sign effect. The effect screen during the gasse sign effect shows the number of remaining games, the number of remaining AT games, the number of acquired games, and the pressing order of the stop switches 8L, 8C, and 8R. Note that the production screen during the Gase sign production is the same as the production screen during the sign production. Thereby, even if a player sees the production | presentation screen, it cannot distinguish between during a prelude production | presentation and during a gasse prelude production | presentation.

  FIG. 19B shows an example of an effect screen when one game has elapsed from FIG. 19A and a gasse sign effect is being executed. In the example shown in the figure, the number of remaining games of the gasse sign game is 3G, the number of AT remaining games is 3, the number of acquired games is 91, and the stop is performed in the order of middle reel, right reel, left reel. Show.

  In this example, it is determined that the gasse sign effect is to be executed in the game in which the effect shown in FIG. 19B is performed. Further, in the present embodiment, the execution process of the gasse sign effect is performed by the effect control board 90. For example, the storage capacity of the ROM 91b included in the sub control unit 91 is generally larger than the storage capacity of the ROM 41b included in the main control unit 41. For this reason, when performing the control of the sign indication effect on the effect control board 90, the capacity of the program can be increased. Therefore, in the present embodiment, when executing the gasse sign effect, the number of AT remaining games is confirmed, and the number of games of the gasse sign effect is distributed according to the number of remaining AT games. In addition, a process is performed to control so that the harsh sign effect is not continued. Specifically, the sub-control unit 91 performs a process of distributing the number of games for the gasse sign effect so that the number of games for the gaze sign effect is equal to or less than the number of remaining AT games. As a result, even if the AT game is over, it is possible to prevent the gauze sign effect from continuing, and it is possible to execute an effect without a sense of incongruity.

  FIG. 19 (C) shows an example of an effect screen during a gasse sign effect similar to FIG. 19 (B). Note that FIG. 19C is an example of an effect screen when two games have elapsed from FIG. In the example shown in the figure, the remaining number of games of the Gase precursory game is 1G, the remaining number of AT games is 1 game, the number of acquired games is 97, and it is stopped in the order of left reel, right reel, and middle reel. Show. As described above, in this embodiment, the gasse sign effect is executed so that the number of games of the gasse sign effect is equal to or less than the number of remaining AT games.

  FIG. 19D shows an example of an effect screen during an extra special zone absence notification effect. FIG. 19 (D) shows an example of an effect screen when one game has elapsed from FIG. 19 (C) and an extra special zone absence notification effect is being executed. In the example shown in the figure, the number of acquired sheets is 103, which indicates that the added special zone is not entered. In addition, since the AT game is over, the reel stop order is not displayed.

  FIG. 19E shows an example of an effect screen during a normal game. FIG. 19 (E) shows an example of an effect screen when one game has elapsed from FIG. 19 (D) and a normal game is being executed. In the illustrated example, an image of a character walking is displayed.

[Status counter processing]
Next, the state counter process (Sc6b) executed during the main process shown in FIG. 9 will be described. FIG. 20 is a flowchart showing the control contents of the state counter process executed by the main control unit at the start of the game (before the reel control process Sc7).

  The main control unit 41 determines whether or not the gaming state is a notification state based on the gaming state set in the state control process executed in the gaming end time setting process of Sc8 in FIG. 9 (Sh1). The notification state is a gaming state in which an added special zone presence notification effect (for example, FIG. 17D or FIG. 18E) is executed. When it is determined that the gaming state is a notification state (Y in Sh1), the main control unit 41 sets an additional specialized zone counter (Sh2). Thereby, it is possible to add the gaming state from the next game and shift to the specialized zone state. In the present embodiment, since the additional special zone is between five games, the main control unit 41 sets 5 in the additional special zone counter. After setting the additional specialized zone counter, the main control unit 41 turns off the notification flag (Sh3).

  When it is determined in Sh1 that the gaming state is not a notification state (N in Sh1), the main control unit 41 is based on the gaming state set in the state control process executed in the gaming end time setting process in Sc8 of FIG. Then, it is determined whether or not the game state is an added special zone state (Sh4). The added special zone state is a gaming state in which an added special zone (for example, FIG. 17E or FIG. 18F) is executed.

  When it is determined in Sh4 that the gaming state is the added special zone state (Y in Sh4), the main control unit 41 determines whether or not the AT game number is won in this game (Sh5). The additional lottery for the number of AT games is executed, for example, in the internal lottery process of Sc6a in FIG. In addition, when the number of AT games is extra lottery, if the game state is in the special zone state, the AT game will be played at a predetermined rate if the player wins a rare role such as strong cherry, strong bell, or strong watermelon. You may make it win a number addition. Also, the number of AT games to be added may be determined at a predetermined ratio.

  If it is determined that the number of AT games is won in Sh5 (Y in Sh5), the main control unit 41 adds the number of added games won in this game to the AT counter (Sh6). The AT counter is a counter that counts the number of AT remaining games.

  When it is determined that the number of AT games has not been won in Sh5 (N in Sh5), or when the number of added games won in Sh6 is added to the AT counter, the main control unit 41 specializes the addition 1 is subtracted from the zone counter (Sh7), and the state counter process is terminated. The extra special zone counter is a counter that counts the number of remaining games in the extra special zone.

  When it is determined in Sh4 that the gaming state is not the added special zone state (N in Sh4), the main control unit 41 is set in the state control process executed in the game end time setting process in Sc8 of FIG. Based on the above, it is determined whether or not the gaming state is a precursor effect state (Sh8). The precursor effect state is a gaming state in which a precursor effect (for example, FIGS. 17B, 17C, 18B, 18C, and 18D) is executed.

  When it is determined in Sh8 that the gaming state is the precursor effect state (Y in Sh8), the main control unit 41 determines whether or not the AT counter is 2 (Sh81). When it is determined that the AT counter is 2 (Y in Sh81), the main control unit 41 rewrites the indication effect counter to 1 (Sh82). As described above, in the present embodiment, when the number of AT remaining games is 2, by rewriting the number of remaining games of the predecessor effect to 1, a special period (predecessor effect + addition special zone presence notification) when the AT ends. The number of production games) is also controlled to end.

  When it is determined in Sh81 that the AT counter is not 2 (N in Sh81), or when the sign effect counter is rewritten to 1 in Sh82, the main control unit 41 subtracts 1 from the sign effect counter (Sh9). The sign effect counter is a counter that counts the number of remaining games that execute the sign effect.

  After subtracting 1 from the sign effect counter, the main control unit 41 determines whether or not the sign effect counter is 0 (Sh10). When it is determined that the indication effect counter is 0 (Y in Sh10), the main control unit 41 turns on the notification flag (Sh11). The notification flag is a flag indicating whether or not to shift to the notification effect state. Specifically, when the notification flag is ON, it indicates that the state is shifted to the notification effect state. That is, when the sign effect counter is 0 and the sign effect ends, the main control unit 41 turns on the notification flag and instructs to shift to the notification effect state. Thereby, the gaming state of the next game can be shifted to the notification effect state.

  When it is determined in Sh8 that the gaming state is not a precursor effect state (N in Sh8), the main control unit 41 is based on the gaming state set in the state control process executed in the gaming end time setting process in Sc8 of FIG. Then, it is determined whether or not the gaming state is the AT state (Sh12). The AT state is a gaming state in which AT control (for example, FIGS. 17A, 17G, 18A, 18H, and 19A) is executed.

  When it is determined in Sh12 that the gaming state is the AT state (Y in Sh12), the main control unit 41 determines whether or not the additional special zone is won in the internal lottery process of Sc6a in FIG. 9 (Sh13). . If it is determined that the bonus special zone is won (Y in Sh13), the main control unit 41 determines the allocation of the number of games of the precursor effect, and sets the determined number of games of the precursor effect in the precursor effect counter (Sh14). ).

  FIG. 21 is a diagram showing a precursor effect game number distribution table in the present embodiment. In the example shown in the drawing, the ratio of setting the number of warning effect games to “5 games” is 80%, the rate of setting the number of warning effect games to “10 games” is 15%, and the number of warning effect effects games is “20 games”. The ratio is 5%. In the processing of Sh14, the main control unit 41 determines the distribution of the number of games of the precursor effect at the ratio specified in the precursor effect game number distribution table shown in FIG. As described above, in the present embodiment, the number of precursor effect games is set to any one of a plurality of lengths. Thereby, a player can be made to pay attention to how much the number of sign effect games (special period) is set, and the interest of the game can be improved.

  It should be noted that the number of games for the indication effect is not limited to the example shown in FIG. 21 and may be any number of games. Further, the distribution ratio of the number of games of the sign effect is not limited to the example shown in FIG. 21 and may be any ratio.

  When the notification flag is turned off in Sh3, or when it is determined that the precursor effect counter is not 0 in Sh10 (N in Sh10), or when the notification flag is turned on in Sh11, or specialized by adding in Sh13 When it is determined that the zone has not been won (N in Sh13), or when the number of games of precursor effect is set in the precursor effect counter in Sh14, the main control unit 41 determines whether or not the AT counter is greater than zero. Determine (Sh15). When it is determined that the AT counter is greater than 0 (Y in Sh15), the main control unit 41 subtracts 1 from the AT counter (Sh16), and ends the state counter process. On the other hand, when it is determined that the AT counter is 0 or less (N in Sh15), the main control unit 41 ends the state counter process.

  When it is determined in Sh12 that the gaming state is not the AT state (N in Sh12), the main control unit 41 determines whether or not the additional special zone is won in the internal lottery process of Sc6a in FIG. 9 (Sh17). When it is determined that the AT is won (Y in Sh17), the main control unit 41 sets the initial number of games of the winning AT in the AT counter (Sh18), and ends the state counter process. On the other hand, if it is determined that the AT is not won (N in Sh17), the main control unit 41 ends the state counter process.

  As described above, in the present embodiment, the state counter process is executed at the start of the game (before the reel control process Sc7). For example, the main control unit 41 updates the values of various counters such as the indication effect counter at the start of the game.

[State control processing]
Next, the state control process executed in the game end setting process (Sc8) of the main process shown in FIG. 9 will be described. FIG. 22 is a flowchart showing the control contents of the state control process executed by the main control unit during the game end setting process of the main process (after the reel control process Sc7). In the state control process, the gaming state of the slot machine 1 is set.

  The main control unit 41 determines whether or not the notification flag set in the state counter process of FIG. 20 is ON (Si1). When it is determined that the notification flag is ON (Y in Si1), the main control unit 41 sets the gaming state to “notification state” (Si2), and ends the state control process.

  When it is determined that the notification flag is not ON in Si1 (N in Si1), the main control unit 41 determines whether or not the additional specialized zone counter set in the state counter process of FIG. 20 is greater than 0 (Si3 ). When it is determined that the added special zone counter is greater than 0 (Y in Si3), the main control unit 41 sets the gaming state as “added specialized zone state” (Si4), and ends the state control process.

  When it is determined that the added specialized zone counter is less than or equal to 0 in Si3 (N in Si3), the main control unit 41 determines whether or not the precursor effect counter set in the state counter process of FIG. (Si5). When it is determined that the precursor effect counter is greater than 0 (Y in Si5), the main control unit 41 sets the gaming state as “predictor effect state” (Si6), and ends the state control process.

  When it is determined in Si5 that the indication effect counter is 0 or less (N in Si5), the main control unit 41 determines whether or not the AT counter set in the state counter process of FIG. 20 is greater than 0 (Si7). . When it is determined that the AT counter is greater than 0 (Y in Si7), the main control unit 41 sets the gaming state as “AT state” (Si8), and ends the state control process.

  When it is determined in Si7 that the AT counter is 0 or less (N in Si7), the main control unit 41 sets the gaming state to “normal state” (Si9) and ends the state control process.

  As described above, in this embodiment, the state control process is performed at the end of the game (after the reel control process Sc7), and the game state is set. For example, the main control unit 41 adds the game state to the special zone state when the notification flag is OFF and the special zone counter is 0 or less at the end of the game. Thereby, it can prevent being controlled to the game state which is not intended.

[Timer interrupt processing (sub)]
Next, timer interrupt processing (sub) executed by the sub control unit 91 (CPU 91c) at intervals of 1.12 ms based on the count value of the internal clock will be described.

  As shown in FIG. 23, in the timer interrupt process (sub), the sub control unit 91 first saves the register in use to the stack area (Sp1). Next, a power failure determination process is performed (Sp2). In the power failure determination process, it is determined whether or not a voltage drop signal is input from the power failure detection circuit 48. If a voltage drop signal is input, whether or not the voltage drop signal is input in the previous power failure determination process as well. If a voltage drop signal has been input in the previous power failure determination process, it is determined that a power failure has occurred, and a power interruption flag indicating that is set.

  After the power failure determination process in the step of Sp2, it is determined whether or not the power interruption flag is set (Sp3). If the power interruption flag is set, the process proceeds to a power interruption process (sub). In the power interruption process (sub), the backup flag used in the startup process (sub) is set after the backup data is created, and the checksum is calculated by calculating the exclusive OR of the backup data.

  If the power interruption flag is not set, command analysis processing is executed (Sp4). In the command analysis process, it is determined whether or not a command is stored in the command buffer. If the command is stored in the command buffer, the command is acquired from the command buffer. And the process according to the acquired command is performed.

  Next, if the sub-control unit 91 determines that the gaming state is one of the AT state, the precursor effect state, or the notification state based on the command analyzed in the command analysis process of Sp4, If it is determined that the state is other than that, the control is not performed to the AT (Sp4). For example, when the sub-control unit 91 controls the AT, a symbol combination advantageous to the player is received on the winning line LN when receiving a command transmitted when a predetermined lottery role is won by the internal lottery process. The operation procedure (push order) for stopping is specified.

  Next, the sub-control unit 91 executes an effect according to the gaming state, the winning combination, etc. (Sp6). In addition, when controlling to AT in Sp5, the sub-control part 91 specifies the operation procedure (push order) for stopping the symbol combination advantageous to the player on the winning line LN (for example, 17A, 17G, 18A, 18H, and 19A) are executed. This allows the player to stop an advantageous symbol combination on the winning line LN, which is advantageous.

[Direction execution process]
Next, details of the effect execution process (Sp6) of FIG. 23 will be described. FIG. 24 is a flowchart showing the control content of the effect execution process executed by the sub control unit in the timer interrupt process (sub).

  The sub-control unit 91 determines whether or not the gaming state is a notification state based on the result analyzed in the command analysis process of Sp4 in FIG. 23 (Sj1). When it is determined that the gaming state is the notification state (Y in Sj1), the sub-control unit 91 executes an additional special zone presence notification effect (for example, FIG. 17D or FIG. 18E) (Sj2). ), The effect execution process ends. Note that, when the gaming state is a notification state, AT control is performed. For this reason, the sub-control unit 91 specifies an operation procedure (push order) for stopping a symbol combination advantageous to the player on the winning line LN in the added special zone notification effect (for example, FIG. 17 ( D) and FIG. 18 (E)) are also executed.

  When it is determined in Sj1 that the gaming state is not the notification state (N in Sj1), the sub-control unit 91 adds the gaming state in the specialized zone state based on the result analyzed in the command analysis process of Sp4 in FIG. It is determined whether or not there is (Sj3). When it is determined that the gaming state is the added special zone state (Y in Sj3), the sub-control unit 91 executes the added special zone effect (for example, FIG. 17E or FIG. 18F) ( Sj4), the effect execution process is terminated. At the time of the final game in the specialization zone, when the third stop reel is stopped (at the end of the specialization zone), an effect screen when the final game in the specialization zone has ended (for example, FIG. 17F and FIG. 18G) are displayed.

  If it is determined in Sj3 that the gaming state is not the added special zone state (N in Sj3), the sub-control unit 91 determines that the gaming state is a precursor effect state based on the result analyzed in the command analysis process of Sp4 in FIG. It is determined whether or not (Sj5). When it is determined that the gaming state is the precursor effect state (Y in Sj5), the sub-control unit 91 performs the precursor effect (for example, FIGS. 17B, 18C, 18B, 18C, and 18D). Is executed (Sj6). As described above, when the precursor effect counter is larger than 0 (when the special period is set), the precursor effect is performed. Thereby, the effect according to whether the precursor effect period (special period) is set can be performed, and the interest of the game can be improved.

  Note that the number of remaining games of the precursor game displayed in the precursor effect is a value based on the result analyzed by the command analysis process of Sp4 in FIG. Further, when the gaming state is a precursor effect state, AT control is performed. For this reason, the sub-control unit 91 specifies an operation procedure (push order) for stopping a symbol combination advantageous to the player on the winning line LN in the warning effect (for example, FIGS. 17B and 17C). 18 (B), (C), and (D)) are also executed.

  After executing the precursor effect in Sj6, the sub-control unit 91 determines whether or not the gasse precursor effect counter is greater than 0 (Sj7). When it is determined that the gasse sign effect counter is greater than 0 (Y in Sj7), the sub-control unit 91 sets the gase sign effect counter to 0 (Sj8) and ends the effect execution process. As a result, even when the gaming state shifts to the precursor effect state while the gasse predictor effect is being executed, it is possible to stop the gasse predictor effect and execute the precursor effect.

  On the other hand, if it is determined in Sj7 that the gasse sign effect counter is 0 or less (N in Sj7), the sub-control unit 91 ends the effect execution process.

  If it is determined in Sj5 that the gaming state is not a precursor effect state (N in Sj5), the sub-control unit 91 determines whether the gaming state is the AT state based on the result of analysis in the command analysis process of Sp4 in FIG. It is determined whether or not (Sj9). When it is determined that the gaming state is not the AT state (N in Sj9), the sub-control unit 91 executes a normal effect (for example, FIG. 19E) and ends the effect execution process.

  When it is determined in Sj9 that the gaming state is the AT state (Y in Sj9), the sub-control unit 91 determines whether or not the gasset sign effect counter is greater than 0 (Sj11). When it is determined that the gasse sign effect counter is 0 or less (N in Sj11), the sub-control unit 91 determines whether or not to execute the gasse sign effect at a predetermined ratio (Sj12). It should be noted that the ratio of whether or not to execute the gasse sign effect may be any ratio. Further, for example, when the internal lottery is off, the gasse sign effect may be executed at a predetermined rate. In addition, for example, when a small role is won in the internal lottery, a gasse sign effect may be executed at a predetermined rate.

  In addition, the process of determining whether or not to execute the gasse sign effect in Sj12 at a predetermined ratio is not executed when the gaming state is the notification effect state or the sign effect state. In other words, when the specific period is set (in the precursor effect state or the notification effect state), the gaze precursor effect is not executed. Thereby, the production according to whether the special period is set can be executed, and the interest of the game can be improved.

  If it is determined in Sj12 that the gasse sign effect is not to be executed (N in Sj12), the sub-control unit 91 performs the AT effect (for example, FIGS. 17A and 17G, FIGS. 18A and 18H, FIG. 19A) is executed (Sj13), and the effect execution process is terminated.

  When it is determined in Sj12 that the harsh sign effect is to be executed (Y in Sj12), the sub-control unit 91 determines that the value is less than the value of the AT counter based on the result analyzed in the command analysis process of Sp4 in FIG. The number of games of the prelude effect is selected, and the selected number of games of the prelude effect is set as the value of the prelude effect counter (Sj14). For example, in the present embodiment, the sub-control unit 91 selects any number of games among 5 games, 10 games, and 20 games as the number of games for the gasse sign effect. For example, the selection ratio of the number of games for the gaze precursor effect may be the same as or different from the precursor effect game number distribution table shown in FIG.

  In addition, when the number of games of the selected gasse sign effect is larger than the value of the AT counter, the value of the AT counter is set as the number of games of the gaze sign effect. For example, even if 10 games are selected as the number of games for the gasse sign effect, if the value of the AT counter is 3, the number of games for the gaze sign effect is set to three games.

  As described above, in the present embodiment, when executing the GASE sign effect, the number of AT remaining games is confirmed, and the number of games of the GASE sign effect is distributed according to the number of remaining AT games, and the AT game ends. Even so, the control process is performed so as not to continue the harsh sign effect. Specifically, the number of games in the Gase Prediction effect is distributed so that the number of remaining AT games is the same as the number of games in the Gase Prediction effect, or the number of games in the Gase Prediction effect is less than the number of remaining AT games. . As a result, even if the AT game is over, it is possible to prevent the gauze sign effect from continuing, and it is possible to execute an effect without a sense of incongruity.

  If it is determined in Sj11 that the gasse warning effect counter is greater than 0 (Y in Sj11), or if the value of the gasse warning effect counter is set in Sj14, the sub-control unit 91 causes the gasset warning effect counter (for example, FIG. B) (C)) is executed (Sj15). Note that the number of remaining games of the gasse sign game displayed as a gasse sign effect is the value of the gasse sign effect counter. In addition, when the gaming state is a gasse sign effect state, AT control is performed. Therefore, the sub-control unit 91 produces an effect (for example, FIGS. 19B and 19C) that specifies an operation procedure (push order) for stopping a symbol combination that is advantageous to the player on the winning line LN in the gasse sign effect. )) Is also executed.

  When the gasse sign effect is executed in Sj15, the sub-control unit 91 subtracts 1 from the gasse sign effect counter (Sj16), and ends the effect execution process. In addition, when 1 is subtracted from the Gase precursor effect counter in Sj15, when the Gase precursor effect counter becomes 0, the sub-control unit 91 executes an extra special zone absence notification effect regardless of the game state in the next game. . In the next game, when the game state is the AT state when executing the extra special zone absence notification effect, the sub-control unit 91 performs an operation for stopping a symbol combination advantageous to the player on the winning line LN. An effect that specifies the procedure (push order) is also executed. In addition, when the game state is the normal state when executing the extra special zone absence notification effect in the next game, the sub-control unit 91 performs an operation for stopping a symbol combination advantageous to the player on the winning line LN. An effect that specifies the procedure (push order) is not executed.

  According to the state counter process, the state control process, and the effect execution process described above, in this embodiment, the gaming state becomes the AT state until the number of remaining AT games becomes zero (until the end condition is satisfied), which is advantageous for the player. An effect that specifies an operation procedure (push order) for stopping the symbol combination on the winning line LN is executed (advantageous control advantageous to the player is performed). In addition, when the gaming state is the AT state (in an advantageous state), there is a case where a period for executing the warning effect and the special zone presence notification effect is set. In the present embodiment, when an additional special zone is won, a period for executing a precursor effect and an additional special zone notification effect is set. At this time, regardless of the number of AT remaining games, the number of games of the sign effect is set to any one of 5 games, 10 games, and 20 games. That is, the period (special period) for executing the warning effect and the special effect zone presence notification effect is set to any of 6 games, 11 games, and 21 games.

  In the present embodiment, when the number of remaining AT games is 0 when the period (special period) for executing the warning effect and the special effect zone presence notification effect is set, the warning effect and the special effect are added. Control is also performed so that the period (special period) for performing the notification effect with the conversion zone is also ended. As described above, in the present embodiment, when the indication effect is started when the “number of indication effect games + the number of added special zone presence notification effects” is smaller than the number of AT remaining games, the AT remaining game is started. When the number becomes 0, the period for executing the indication effect and the special zone presence notification effect is ended. As a result, the control of the AT is completed during the indication effect and the special zone presence notification effect without performing the process of checking the number of AT remaining games and distributing the number of indication effects according to the number of AT remaining games. It will not happen. Therefore, the process can be simplified and the capacity of the program can be reduced. For example, since the storage capacity of the ROM 41b of the main control unit 41 is generally small, when setting the number of precursor games on the game control board 40, the setting process of the number of precursor games is simplified and the data capacity of the program is reduced. It is desirable to reduce.

  Further, in the present embodiment, when the AT remaining game number becomes 0, the period for executing the precursor effect and the special zone presence notification effect is ended. Therefore, in this embodiment, for example, when the number of remaining AT games is 3, even if the number of remaining AT games is 3 or more, as shown in FIG. 18D, the number of remaining AT games is 2 games. Sometimes, the number of remaining games of the sign effect is rewritten to one game. Also, in such a case, as shown in FIGS. 18B and 18C, the number of games of precursor effects may be displayed on the effect screen of precursor effects more than the number of AT remaining games. On the other hand, when executing the gasse sign effect, the number of AT remaining games is confirmed and the number of games for the gaze sign effect is distributed according to the number of remaining AT games. Processing to control not to continue is performed. In other words, there is no case where the number of games of the gasse sign effect is larger than the number of remaining AT games. As a result, when the number of games of the prelude effect is larger than the number of AT remaining games, there is no possibility of the prelude effect, so the player recognizes that the winning of the specialization zone has been confirmed Can improve the interest of the game.

[Modification 1]
In the above-described example, the game state includes the “normal state”, “AT state”, “precursor effect state, notification state”, and “addition-specific zone”, but the BIG bonus in each state The winning probabilities may be different. FIG. 25 is a diagram showing a BIG bonus winning probability table. In the illustrated example, the winning probability of the BIG bonus when the gaming state is the “normal state” is 1/315. In addition, when the gaming state is the “AT state”, the winning probability of the BIG bonus is 1/256. In addition, when the game state is the “prediction effect state, the notification state”, the winning probability of the BIG bonus is 1/99. Further, when the gaming state is the “additional specialization zone state”, the winning probability of the BIG bonus is 1/200.

  Thus, by making the winning probability of the BIG bonus different depending on the gaming state, it is possible to make the player pay more attention to which gaming state, and to improve the interest of the game. In addition, when the sign production state or the notification state is set (when the special period is set), since the BIG bonus winning probability is high, the sign production state or the notification state is set (the special period is set). It is possible to draw more attention to the player and improve the interest of the game. As in the example in which the winning probability of the BIG bonus is different in each state of “normal state”, “AT state”, “prediction effect state, notification state”, and “addition specialization zone”, AT Any winning probabilities such as the winning probabilities and the small role winning probabilities may be made different.

[Modification 2]
In the above-described example, the game state includes the “normal state”, “AT state”, “prediction effect state, notification state”, and “addition special zone”. The winning probabilities for the BIG bonus and the REG bonus may be different. For example, when the game state is “normal state”, “AT state”, or “additional special zone state” (when no special period is set), the winning probability of the REG bonus is higher than the BIG bonus, and the game When the state is “prediction effect state, notification state” (when a special period is set), the BIG bonus winning probability may be set higher than the REG bonus. Note that both the BIG bonus and the REG bonus are advantageous to the player, but the BIG bonus is more advantageous than the REG bonus.

  Thus, by making the winning probabilities of the BIG bonus and the REG bonus different depending on the gaming state, it is possible to make the player pay more attention to which gaming state, and to improve the interest of the game. In addition, when in the precursor effect state or the notification state (when a special period is set), the winning probability of the BIG bonus is higher than the REG bonus (the player's advantage is higher). Therefore, it is possible to make the player pay more attention to whether it is the precursor effect state or the notification state (whether the special period is set), and to improve the interest of the game.

[Modification 3]
In the above-described example, when the precursor effect counter is set (when the special period is set), the precursor effect is executed, but the present invention is not limited to this. For example, when the sign effect counter is set, the execution ratio of a predetermined effect (for example, an effect that suggests that there is a high possibility that the bonus special zone is won) is increased, and the sign effect counter is set. If not, the execution ratio of the predetermined effect is lowered. Thereby, the player can recognize that the precursor effect has started by recognizing that the execution frequency of the predetermined effect has increased. In such a case, even if the precursor effect is started, the predetermined effect is not always executed, so the game (timing) at which the precursor effect is started cannot be accurately grasped. The starting game can be guessed. Also, in such a case, the number of remaining games of the prelude effect is not displayed on the effect screen, but the game that presumes that the predecessor effect is continued from the game that is presumed to be the game in which the predecessor effect has been started. By counting the number by the player, the player can estimate the number of games in which the prelude effect is being executed.

[Modification 4]
In the above-described example, the example using the AT as the advantageous control advantageous to the player has been described, but the present invention is not limited to this. The advantageous control advantageous to the player may be any control as long as it is advantageous to the player. For example, the advantageous control advantageous to the player may be a control for increasing the winning ratio of the small role. Thereby, the probability that a medal can be acquired can be increased, which is advantageous to the player. Further, for example, the advantageous control advantageous to the player may be RT (replay time) which is control for increasing the replay winning ratio. As a result, the probability of replaying can be increased, which is advantageous to the player. In addition, for example, as advantageous control advantageous to the player, an effect that specifies an operation procedure (push order) for stopping a symbol combination advantageous to the player on the winning line LN is executed, and a replay winning is performed. It may be ART (assist replay time) which is control for increasing the ratio. As a result, symbol combinations advantageous to the player can be arranged on the winning line, and the probability of replaying can be increased, which is advantageous to the player.

[Modification 5]
In the above-described example, the countdown effect is not performed even when the number of remaining AT games is equal to or less than a certain number of games (for example, 3 games), but the number of remaining AT games is equal to or less than the certain number of games. In some cases, a countdown effect may be performed. As a specific example, as the countdown effect, when the number of AT remaining games is 3, the game screen displays “3 remaining games”, and when the number of AT remaining games is 2, the game screen displays “2 remaining games”. When the number of AT remaining games is one game, “1 remaining game” may be displayed on the effect screen. In addition, when the precursor effect is started during the countdown effect, the countdown effect may be stopped and the precursor effect may be started. Thereby, when the countdown effect is stopped, it is possible to increase the degree of expectation that is controlled in a special state (for example, an added special zone) advantageous to the player, which is different from the advantageous state (for example, the AT state). Can improve the interest of the game.

[Modification 6]
In the example described above, the number of games in the additional specialization zone is constant (five games) even if the number of games of the indication effect is different, but this is not restrictive. For example, the degree of advantage of the additional specialization zone may be varied depending on the number of games of the sign effect. For example, the number of games in the specialization zone may be increased as the number of games of the sign effect increases. Further, for example, the number of games in the specialization zone may be shortened as the number of games of the sign effect increases. In addition, for example, the longer the number of predecessor games, the higher the winning probability of the number of additional games in the additional specialization zone. In addition, for example, the longer the number of games of the sign effect, the lower the winning probability of the number of additional games in the additional specialization zone. In addition, for example, the longer the number of games of the sign effect, the larger the number of additional games at the time of winning one additional game number. Also, for example, the longer the number of games for the sign effect, the smaller the number of additional games at the time of winning one additional game number. Thereby, a player can be made to pay attention to how many game numbers of the sign effect are set, and the interest of the game can be improved.

[Modification 7]
In the above-described example, when the AT counter is 2, the value of the indication effect counter is rewritten to 1, but the present invention is not limited to this. For example, if the value of the precursor effect counter is rewritten so that the predictor effect and the special zone presence notification effect end when the number of AT remaining games becomes 0, the value of the predictor effect counter is rewritten at an arbitrary timing. May be. That is, if the value of the precursor effect counter is rewritten so that the number of remaining AT games and the number of games of the precursor effect + additional special zone notification effect are the same, the indication effect counter The value may be rewritten.

  For example, the value of the indication effect counter may be rewritten to 2 at the timing when the AT counter is 3. Further, for example, the value of the indication effect counter may be rewritten to 3 when the AT counter is 4. As described above, even when the value of the precursor effect counter is rewritten at an arbitrary timing, when the AT remaining game number becomes zero, the precursor effect and the special zone presence notification effect can be ended.

[Effects of the present embodiment]
Next, main effects obtained by the embodiment described above will be described.
(1) In the present embodiment, the main control unit 41 and the sub control unit 91 (advantageous control means) are advantageous for the player until the AT remaining game count becomes zero (until the end condition is satisfied). Is controlled to an AT state (advantageous state) for performing advantageous control advantageous to a player who executes an effect that specifies an operation procedure (push order) for stopping the player on the winning line LN. Also, the main control unit 41 (privilege grant means) grants an extra special zone (privilege) when the extra special zone is won in the AT state (advantageous state) (when special conditions are established). In addition, the main control unit 41 (special period setting means) performs a precursor effect and an additional special zone presence notification effect when an additional special zone (privilege) is granted in the AT state (advantageous state). (Special period) is set. Further, the sub-control unit 91 (special period effect executing means) performs the sign effect when the period (special period) for executing the sign effect and the added special zone notification effect in the AT state (advantageous state) is set. The effect is executed in a different execution mode from the case where the period (special period) for executing the special effect zone presence notification effect is not set. Further, the main control unit 41 (special period elapsed determination means) determines whether a period (special period) for executing the precursor effect and the added special zone presence notification effect has elapsed. Also, the main control unit 41 (special period setting means) does not refer to the remaining period until the number of remaining AT games becomes 0 (until the end condition is satisfied), and the sign effect and added special zone presence notification effect. Set the period (special period) for executing. Further, the main control unit 41 (privilege granting means) determines the special zone (privilege) to be added based on the determination that the period (special period) for executing the warning effect and the special zone presence notification effect has passed. Give. Further, the main control unit 41 (special period elapse determination means) is configured such that the number of AT remaining games becomes 0 when the period (special period) for executing the indication effect and the special zone presence notification effect is set. In the case where the end condition is satisfied, it is determined that the period (special period) for executing the indication effect and the special zone presence notification effect is added.

  According to such a configuration, it is possible to improve the interest of the game while simplifying the processing.

  (2) Moreover, in this Embodiment, a precursor production | presentation counter (counter) measures the period (special period) which performs a notification production | presentation with a precursor production | presentation and an addition special zone. In addition, the main control unit 41 (counter rewriting means) executes the warning effect counter (counter) with the warning effect and the special zone presence notification effect when the AT remaining game count becomes zero (the end condition is satisfied). It is rewritten to a value for determining that the period to be performed (special period) has elapsed. Also, the main control unit 41 (special period elapsed determination means) is based on the value of the sign effect counter (counter) and the period (special period) during which the sign effect and the special zone presence notification effect are executed has elapsed. You may make it determine.

  According to such a configuration, it is possible to determine that the period (special period) for executing the indication effect and the special zone presence notification effect is completed by a simple process.

  (3) Moreover, in this Embodiment, the sub control part 91 (effect control means) controls execution of an effect. In addition, the main control unit 41 (special period setting means) can specify that the period (special period) for executing the sign effect and the added special zone presence notification effect is set. A command (specific period setting information) indicating the notification effect state is notified to the sub-control unit 91 (effect control means). In addition, the sub-control unit 91 (production control means) does not execute the gasse sign production in response to a command (specific period setting information) indicating that the gaming state is the predation production state or the notification production state (controls the execution of the production). You may do it.

  According to such a structure, the effect according to whether the special period is set can be performed, and the interest of a game can be improved.

  (4) Moreover, in this Embodiment, the sub control part 91 (false special period setting means) sets a gasset precursor period (false special period), when an additional specialization zone (privilege) is not provided. Further, the sub-control unit 91 (false special period setting means) refers to the remaining period until the AT remaining game number becomes 0 (the end condition is satisfied), and the AT remaining game number becomes 0 (the end condition is It is also possible to set a pre-gase period (false special period) so as not to cross over.

  According to such a configuration, there is no case where the pre-gase period (false special period) is longer than the remaining period until the number of remaining AT games becomes zero (the end condition is satisfied).

  In the present embodiment, when the number of remaining AT games becomes 0, the period for executing the indication effect and the special zone presence notification effect is ended. Therefore, in this embodiment, for example, when the number of remaining AT games is 3, even if the number of remaining AT games is 3 or more, as shown in FIG. 18D, the number of remaining AT games is 2 games. Sometimes, the number of remaining games of the sign effect is rewritten to one game. Further, in such a case, as shown in FIGS. 18B and 18C, there are cases where the number of games of precursor effects is larger than the number of AT remaining games.

  As a result, when the number of games of the prelude effect is larger than the number of AT remaining games, there is no possibility of the prelude effect, so the player recognizes that the winning of the specialization zone has been confirmed Can do. Therefore, the player can be made to pay more attention to the length of the period (special period) in which the sign effect and the special effect zone presence notification effect are executed, and the length of the gasse sign period (false special period).

  (5) Further, in the present embodiment, the main control unit 41 (special period setting means) is one of 5 games, 10 games, or 20 games (any one of a plurality of lengths). A period (special period) during which the notification effect is displayed may be set.

  According to such a configuration, it is possible to make the player pay attention to how much the special period is set, and it is possible to improve the interest of the game.

  (6) Further, in the present embodiment, the sign effect counter (special period counter for measuring the special period) and the main control unit 41 (special period counter) that updates the sign effect counter (special period counter) at the start of the game. Update means), and at the end of the game, main control for setting the gaming state after the end of the period (special period) for executing the precursor effect and the special zone presence notification effect based on the precursor effect counter (special period counter) And a unit 41 (game state setting means).

  According to such a configuration, it is possible to prevent the game state from being controlled unintentionally.

  (7) In this embodiment, a storage area (vector table area) is provided in which a program address to be executed by the microcomputer (main control unit 41) when an interrupt occurs is provided. When the program is activated, it is determined whether the program address set in the storage area is within a predetermined range. If the program address is not within the predetermined range, the activation of the microcomputer may be limited.

  Specifically, the value set in the vector table area is 0000h (value set in an unused vector table area) or the address area set in 8000h to HPRGEND, that is, in the program area. It is determined whether the program or the like is a value indicating an actually stored area, and the value set in the vector table area is not 0000h, and is not a value indicating an address area set in 8000h to HPRGEND May not be activated.

  According to such a configuration, it is possible to prevent an unintended interrupt process from being executed in advance.

  (8) Further, in the present embodiment, after the internal state setting (startup setting) is performed, the microcomputer has a microcomputer (main control unit 41) that starts execution of the user program (initial setting process), The prohibition of interrupt may be set in the setting of the internal state, and the prohibition of interrupt may be set in the user program when the execution of the user program is started. For example, the main control unit 41 is activated in a state in which interrupts are prohibited, but may be prohibited from interrupting again at Sa1.

  According to such a configuration, it is possible to prevent unintended interrupt processing from being executed.

  (9) In the present embodiment, a plurality of types of timer counter values are set in an area to which consecutive addresses are assigned according to a predetermined rule in the RAM 41c, with a plurality of timers having different uses. It may be updated by a common update process while changing the target address. For example, the process of updating the timer value stored at the specified address is repeatedly executed while changing the specified address for the area where a plurality of types of timer counter values are stored by adding a constant to the current specified address. Thus, a plurality of types of timer values may be updated.

  According to such a configuration, timer value update processing can be executed without increasing the processing capacity.

  As mentioned above, although embodiment and the modification of this invention were demonstrated with drawing, this invention is not limited to this embodiment and the modification. The present invention is not limited to the above-described embodiments and modifications, and various modifications and applications are possible. Further, at least two of the technical matters described in the present embodiment and the modification may be implemented in combination, and the technical matters described in the present embodiment are replaced with the technical matters described in the modification. You may make it carry out, and you may make it implement combining further the technical matter demonstrated by a modification with respect to the said replacement.
