For example, the external bus interface 501 is connected to an external memory or an external input / output device externally attached to the main control unit 41, and transmits / receives address signals, data signals, various control signals, and the like to / from these external devices. Anything to do. In this embodiment, the external bus interface 501 includes an internal resource access control circuit 501A.

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

  The clock circuit 502 provided in the main control unit 41 is a circuit that generates the internal system clock SCLK by, for example, dividing the oscillation signal input to the control external clock terminal EXC by two. In this embodiment, the control clock CCLK generated by the control clock generation circuit 42 is input to the control external clock terminal EXC. The internal system clock SCLK generated by the clock circuit 502 is supplied to various circuits such as the CPU 505 that control the progress of the game in the main control unit 41. The internal system clock SCLK is also supplied to the random number circuit 509 and used to monitor the frequency of the random number clock RCLK supplied from the random number clock generation circuit 43. Further, the internal system clock SCLK may be output from the system clock output terminal CLKO connected to the clock circuit 502 to the outside of the main control unit 41.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

  The main control unit 41 repeatedly loops the process according to the control state until the detection state of the various switches connected to the game control board 40 changes as a basic process, and changes the detection state of the various switches. Execute a process that moves in stages. Further, the main control unit 41 executes a timer interrupt process (main) at regular time intervals (about 0.56 ms in this embodiment). In addition, the execution interval of the timer interrupt process (main) is set to a time longer than the sum of the time required to complete the repeated process according to the control state in the basic process and the execution time of the timer interrupt process (main) Therefore, the process that is repeated according to the control state between the current and next timer interrupt processes (main) is completed at least once.

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

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

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

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

  Similar to the main control unit 41, the effect control board 90 includes a sub CPU 91a, ROM 91b, RAM 91c, and a microcomputer provided with an I / O port 91d. A display control circuit 92 that performs display control of the liquid crystal display 51 connected to the LED, an LED driving circuit 93 that performs drive control of the effect LED 52 and the reel LED 55, an audio output circuit 94 that controls audio output from the speakers 53 and 54, When the power is turned on or when an initialization command from the sub CPU 91a is not input for a certain period of time, a reset circuit 95 that gives a reset signal to the sub CPU 91a and a detection signal input from the effect switch 56 connected to the effect control board 90 are detected. The switch detection circuit 96 outputs time information including date information and time information. The power supply voltage supplied to the timepiece device 97 and the slot machine 1 is monitored, and when a voltage drop is detected, a power drop detection circuit 98 that outputs a voltage drop signal to that effect to the sub CPU 91a, other circuits, etc. , And the sub CPU 91a receives various commands transmitted from the game control board 40 and performs various controls for performing effects, and directly controls each part of the control circuit mounted on the effect control board 90. To control automatically or indirectly.

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

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

  Also, unlike the main control unit 41, the sub control unit 91 interrupts the process even when the timer interrupt process (sub) is being executed when an interrupt is generated based on the reception of the command. The command reception interrupt process is executed at the same time, and the command reception interrupt process is executed with the highest priority even if interrupts that trigger the timer interrupt process (sub) occur at the same time.

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

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

  In order to change the setting value, it is necessary to turn on the power of the slot machine 1 after the setting key switch 37 is turned on. When the setting key switch 37 is turned on and the power is turned on, the setting value read from the RAM 507 is displayed on the setting value display 24 as a display value, and the setting value can be changed by operating the reset / setting switch 38. Transition to the setting change state. When the reset / setting switch 38 is operated in the setting change state, the display value displayed on the setting value display 24 is updated one by one (when further operation is performed from the setting 6, the display returns to the setting 1). . When the start switch 7 is operated, the display value is determined as the set value. Then, when the setting key switch 37 is turned off, the determined display value (setting value) is stored in the RAM 507 of the main control unit 41, and the state shifts to a state in which the game can proceed.

  In order to check the set value, after the game is over, the setting key switch 37 may be turned on in a state where the bet amount is not set. When the setting key switch 37 is turned on in such a situation, the setting value read out from the RAM 507 is displayed on the setting value display 24, thereby shifting to a setting confirmation state in which the setting value can be confirmed. In the setting confirmation state, the game cannot be progressed, and by setting the setting key switch 37 to the off state, the setting confirmation state is ended and the state in which the game can proceed is returned.

  In the slot machine 1 of the present embodiment, the main control unit 41 determines whether or not the voltage drop signal from the power interruption detection circuit 48 is detected every time the timer interruption process (main) is executed. If the determination process is performed and it is determined that the voltage drop signal is detected in the power failure determination process, the power interruption process (main) is executed. In the power interruption process (main), the register is saved in a stack of a RAM 507, which will be described later, and destructive diagnosis data (in this embodiment, 5AH) in which any bit is 1 is stored in the RAM 507, that is, specific data other than 0 is stored. In addition to the storage, the RAM parity adjustment data is calculated so that the RAM parity based on the data stored in all areas of the RAM 507 becomes 0 and stored in the RAM 507. The RAM parity is a value calculated as an exclusive OR of the values stored in each bit of the corresponding area (all areas in this embodiment) of the RAM 507. For this reason, if the RAM parity based on the data stored in all areas of the RAM 507 is 0, the RAM parity adjustment data is 0, and the RAM parity based on the data stored in all areas of the RAM 507 is 1. In this case, the RAM parity adjustment data is 1.

  The main control unit 41 calculates the RAM parity based on the data stored in all areas of the RAM 507 at the time of activation, regardless of whether the system reset or the user reset, and the value of the data for destructive diagnosis And the processing state of the main control unit 41 is restored to the state before the power interruption based on the data stored in the RAM 507 on the condition that the RAM parity is 0 and the value of the data for destruction diagnosis is also correct. However, if the RAM parity is not 0 (in the case of 1) or the value of the destruction diagnosis data is not correct, it is determined that the RAM is abnormal, and the RAM abnormal error code is set in the register to control the RAM abnormal error state. However, the progress of the game is disabled. Unlike the normal error state, the RAM abnormal error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, and a new set value is set in the above-described setting change state. It will not be released until

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

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

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

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

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

  Initialization 1 is an initialization performed when the setting key switch 37 is turned on at the time of startup and transitions to a setting change state, or initialization performed when a RAM abnormality error occurs. In the storage area of the RAM 507, all areas (including the unused area and the unused stack area) except for the important work and the used stack area, that is, the area from the unsaved work to the unused stack area are initialized. The Initialization 2 is initialization performed at the end of the BB. In initialization 2, the area of the RAM 507 includes the general work, the unused area, and the unused stack area, that is, the area from the general work to the unused stack area. It is initialized. Initialization 3 is an initialization performed when the setting key switch 37 is in an off state at the time of startup and the data in the RAM 507 is not destroyed. In the initialization 3, the unsaved work, the unused area, and the The used stack area is initialized. Initialization 4 is initialization performed at the end of one game. In initialization 4, an unused area and an unused stack area in the storage area of the RAM 507 are initialized.

  In this embodiment, initialization 1 is performed before the change of the setting change state. However, the initialization 1 is performed at the end of the setting change state, or both before the change of the setting change state and at the end of the setting change state. Also good.

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

  In the slot machine 1 of this embodiment, as described above, the prescribed number of bets that can be set according to the gaming state (usually inside, BB (RB)) is determined, and is determined according to the gaming state. The game can be started on the condition that the specified number of bets has been set. In the present embodiment, the winning line LN is activated when a specified number of bets according to the gaming state are set.

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

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

  Hereinafter, the internal lottery of the present embodiment will be described. In the internal lottery, it is determined whether or not the above winning combination is permitted before the display results of all the reels 2L, 2C, and 2R are derived and displayed (actually, when the start switch 7 is detected). To do. In the internal lottery, first, a random value for internal lottery (an integer from 0 to 65535) is acquired when the start switch 7 is detected. Specifically, the value of the random number storage work assigned to the RAM 507 is set to the lottery work assigned to the RAM 507. Then, for each combination determined according to the gaming state and whether or not the special combination is carried over, the numerical data stored in the lottery work, the value of the gaming state flag for specifying the gaming state, and the RT described later are specified. The determination is made according to the number of determination values of each combination determined according to the value of the RT flag, the number of bets, and the set value.

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

  In the internal lottery, an internal lottery target, a current gaming state flag value, an RT flag value, and the number of determination values determined corresponding to the set value are stored in a random number for internal lottery (a lottery work). When the result of addition overflows, it is determined that the winning combination is won. For this reason, a winning combination will be won with a probability (number of determination values / 65536) according to the number of determination values.

  If a winning combination of any combination is determined, a winning flag corresponding to the winning combination is set in the internal winning flag storage work assigned to the RAM 507. The internal winning flag storage work consists of a storage area of 2 bytes, of which the upper byte is assigned as the special role storing work for which the special role winning flag is set, and the lower byte is the winning of the general role It is assigned as a general role storage work for which a flag is set. Specifically, when a special combination is won, a special combination winning flag indicating that the special combination is won is set in the special combination storing work, and the winning flag set in the general combination storing work is cleared. When a general combination is won, a winning flag for the general combination indicating that the general combination is won is set in the general combination storing work. If no winning combination is selected, only the general winning combination work is cleared.

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

The main control unit 41 refers to the table index and table creation data stored in the ROM 506 when the rotation of the reel starts and when the reel stops and the reel that is still rotating still remains. A stop control table is created for each reel that is rotating. When any of the stop switches 8L, 8C, and 8R corresponding to the rotating reel is effectively detected, the stop control table of the corresponding reel is referred to and the slip of the referred stop control table is referred to. Based on the number of frames, control is performed to stop the rotation of the reels 2L, 2C, 2R corresponding to the operated stop switches 8L, 8C, 8R.

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

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

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

  The stop control table is data that can specify the number of sliding frames for each timing when the stop operation is performed. In the present embodiment, a stepping motor that makes one turn at a cycle of 336 steps (0 to 335) is used for the reel motors 32L, 32C, and 32R. That is, when the reel motors 32L, 32C, and 32R are driven in 336 steps, the reels 2L, 2C, and 2R make one round. Then, 21 areas (frames) divided every 16 steps (the number of steps that one symbol moves) are defined for one reel, and these areas are areas 0 to 20 from the reel reference position. A number is assigned. On the other hand, the number of symbols arranged on one reel is 21, and symbol numbers 0 to 20 from the reel reference position are assigned to symbols on each reel, so symbols 0 to 20 are assigned to each reel. , Area numbers 0 to 20 are assigned in order. In the stop control table, the number of sliding symbols for each area number is compressed and stored according to a predetermined rule, and the number of sliding symbols for each area number can be acquired by expanding the stop control table. Yes.

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

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

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

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

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

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

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

  When a special role and a small role are elected at the same time, such as when a special role is elected while the special role has been carried over from before the previous game, the winning small role is the maximum in the range of 4 frames on the winning line. The number of sliding frames is fixed so that it can be drawn to the limit, and for the stop operation position where the selected small role cannot be drawn in the range of up to 4 frames in the winning line, the winning special role is in the range of 4 frames in the winning line Then, a stop control table in which the number of sliding frames is determined so as to be pulled in as much as possible is created, and reel stop control is performed. As a result, when a stop operation is performed, if it is possible to stop all the small roles that have been selected in the drawing range of up to 4 frames on the winning line and stop them, control is performed so that the winning combination is stopped. If you can't draw a small role that has been won in the drawing range of up to 4 frames on the line, if you can stop with a special role that has been won in the drawing range of up to 4 frames on the winning line, A control is performed to stop them in a uniform manner, and a winning combination that has not been won will be controlled to be stopped within a 4-frame pull-in range. That is, in such a case, priority is given to the control for aligning the small combination on the winning line over the special combination, and the special combination can be won only when the small combination cannot be drawn. When a special combination and a small combination can be withdrawn at the same time, only the small combination is drawn in, and the small combination is not aligned on the winning line at the same time as the special combination.

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

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

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

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

  Next, commands that the main control unit 41 transmits to the sub control unit 91 will be described.

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

  These commands consist of 1-byte type data indicating the command type and 1-byte extension data indicating the command content, and the sub-control unit 91 can determine the command type from the type data.

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

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

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

  The freeze command is a command indicating whether or not to control the freeze state when it is determined to control to the freeze state, which will be described later, and the timing in the case of controlling to the freeze state. Sometimes sent.

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

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

  The winning determination command is a command that can specify the combination of symbols arranged on the winning line LN, whether or not there is a winning, the type of winning, and the number of medals to be paid out at the time of winning. Sent after.

  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 gaming state command is a command that can specify the gaming state of the next game, the type of RT, and the number of remaining RT games, and is transmitted when the game ends.

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

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

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

  The return command is a command indicating that the main 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. When the setting change state is entered, a setting command indicating the start of the setting change state is transmitted and 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 the setting confirmation state is entered. A confirmation command is sent.

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

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

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

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

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

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

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

  When the sub control unit 91 receives a command from the main control unit 41, the sub control unit 91 executes a command reception interrupt process. In the command reception interrupt process, the command acquired from the command transmission line is stored in the reception buffer provided in the RAM 91c.

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

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

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

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

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

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

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

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

  FIG. 6 to FIG. 9 are diagrams for explaining the types of winning combinations, symbol combinations of winning combinations, and technical matters related to winning combinations. FIG. 10 is a diagram for explaining the gaming state and RT transition controlled by the main control unit 41, and FIG. 11 is a diagram showing an outline of the gaming state and RT.

  As shown in FIG. 10, the slot machine in the present embodiment is controlled to one of the normal gaming state, the inside 1, 2, RB, and BB (RB), and the normal gaming state (hereinafter referred to as the normal gaming state). Is controlled to any one of RT0 to RT4.

  Referring to FIG. 6, special bonuses among the winning combinations include big bonuses 1 to 4 (hereinafter, each big bonus is referred to as BB), regular bonuses 1 and 2 (hereinafter, each regular bonus is referred to as RB). ) 6 types of bonuses are included.

  BB1 is awarded when the combination of “Black 7-Black 7-Black 7” is aligned on the winning line. BB2 is awarded when the combination of “network 7-network 7-network 7” is aligned on the winning line. BB3 is awarded when a combination of “white 7-white 7-white 7” is aligned on the winning line. BB4 is awarded when the combination of “BAR-BAR-BAR” is aligned on the winning line. BB4 is awarded when a combination of “black 7-white 7-net 7” is aligned on the winning line.

  When winning one of BB1 to BB4, the game shifts to a big bonus that is controlled by the game every time during the BB regular bonus (hereinafter referred to as BBRB).

  The big bonus generated due to the winning of any one of BB1 to BB4 is terminated on condition that 316 or more medals have been paid out.

  RB1 wins when a combination of “net 7-net 7-black 7” is aligned on the pay line. RB2 is awarded when the combination of “white 7-white 7-black 7” is aligned on the winning line.

  When winning one of RB1 and RB2, a transition is made to a regular bonus (hereinafter referred to as RB).

  The regular bonus generated due to the winning of either RB1 or RB2 ends on the condition that any winning combination has won 6 times or 12 games have been consumed.

  As shown in FIG. 10, until one of BB1, BB3, or RB2 is won internally, the prize is controlled to 1 / RT0, and after winning one of BB2, BB4, or RB1, the prize is won. Until this is done, the internal control is controlled to 2 · RT0. Further, as shown in FIG. 10, after the big bonus or regular bonus (collectively referred to as a bonus) is completed, the control is performed to normal / RT4.

  Even if one of BB1 to BB4, RB1, or RB2 is won in an internal lottery to be described later, if the stop switches 8L, 8C, and 8R are not operated at an appropriate timing to enable winning of these roles, these I won't win a role. The symbols composing BB1 to BB4, RB1, and RB2 ("black 7", "white 7", and "net 7") are arranged within 5 frames on each of the left reel 2L, middle reel 2C, and right reel 2R. It is because it is not done.

For this reason, it can be said that, in principle, when the promotion replay 2 is won in an internal lottery to be described later, it can be said that, as a rule, it can be awarded regardless of the operation timing of the stop switches 8L to 8R.

  As shown in FIG. 10, after winning a promotion replay (promotion replay 1 or promotion replay 2) in normal / RT1, it is controlled to normal / RT0. As will be described later, the promotion replay is set not to win independently in the internal lottery in normal / RT2 and normal / RT3. Further, when the special combination and the promotion replay are won at the same time in the internal lottery in the normal / RT2 and the normal / RT3, the internal 1 / RT0 or the internal 2 / RT0 is controlled at that time. For this reason, in the normal / RT2 and normal / RT3, the promotion replay is not won. As a result, the normal / RT2 and normal / RT3 are not controlled from the normal / RT3 to the normal / RT0, and the promotion replay is awarded only when the normal / RT1 is selected, and the normal / RT1 is controlled only from the normal / RT1. It is configured as follows.

  The special replay is awarded when a combination of “bell-replay-replay” and “bell-replay-plum” is arranged on the winning line LN. In the left reel 2L, the bell is arranged within 5 frames, in the middle reel 2C, the replay is arranged within 5 frames, and in the right reel 2R, one of the replays and plums is arranged within 5 frames. ing.

  As shown in FIG. 10, after winning the special replay in the normal / RT0, it is controlled to the normal / RT2. As will be described later, the special replay is set so as not to be won by itself in the internal lottery in normal / RT1 and normal / RT3. Further, when the special combination and special replay are won at the same time in the internal lottery in normal / RT1 and normal / RT3, the internal 1 / RT0 or the internal 2 / RT0 is controlled at that time. Therefore, the special replay is not won in normal / RT1 and normal / RT3. As a result, it is configured not to be controlled from normal / RT1, normal / RT3 to normal / RT2, and special replay is awarded only when it is normal / RT0, and only normal / RT0 is controlled to normal / RT2. It is configured as follows.

  Next, the transition outcome will be described with reference to FIG. As shown in FIG. 9, the transition items are “Replay-Orange-Bell”, “Replay-BAR-Bell”, “Plum-Orange-Bell”, “Plum-BAR-Bell”, “Replay-Bell-Orange”. ”,“ Replay-Bell-BAR ”,“ Plum-Bell-Orange ”,“ Plum-Bell-BAR ”,“ Black 7-Orange-Orange ”,“ Black 7-Orange-BAR ”,“ Black 7-BAR- ” "Orange", "Black 7-BAR-BAR", "White 7-Orange-Orange", "White 7-Orange-BAR", "White 7-BAR-Orange", "White 7-BAR-BAR", "Watermelon -Orange-orange "," Watermelon-orange-BAR "," Watermelon-BAR-orange "," Watermelon-BAR-BAR ". In this embodiment, left bells 1 to 4, middle bells 1 to 4 and right bells 1 to 4 which will be described later are elected, and the upper bells which are elected as the first stop other than the reels which become the winning conditions for the middle bells are elected. When the game is missed, the above-mentioned transition outcome is aligned with the winning line LN.

  As shown in FIG. 10, after the transition points are aligned with the winning line LN in the normal / RT0, normal / RT2, and normal / RT3, control is performed to the normal / RT1. Note that, when the transition outcomes are aligned with the winning line LN in the normal / RT1, the normal / RT1 is maintained.

  Next, with reference to FIGS. 12-16, the combination of the lottery object combination read as a lottery object role for each gaming state will be described. In this embodiment, the gaming state is the normal gaming state, the inside one (BB1, BB3, RB2 is elected) or the inside 2 (BB2, BB4, RB1 is won) State), BB (RB), or RB, and the winning combination and the winning probability for the internal lottery are different. Furthermore, if the gaming state is the normal gaming state, at least one of the re-game player and the winning probability to be subject to the internal lottery differs depending on the types of RT0 to RT4. As will be described later as a lottery target combination, a plurality of winning combinations can be read out simultaneously and can be won in duplicate. In FIGS. 12 to 16, “+” is written between winning combinations to indicate that they are simultaneously read out as a lottery target combination in the internal lottery.

  In FIGS. 12 to 16, the lottery target combination is shown in the vertical column, and the gaming state is shown in the horizontal column. In the column where the gaming state intersects with the lottery target, a circle indicates that the lottery target is read out in the gaming state, and a cross indicates the lottery target when in the gaming state. This indicates that the combination is not read out.

  Further, the numerical value shown below the circle indicates the number of determination values of a predetermined set value (for example, set value 1). An internal lottery is performed using the number of determination values. The denominator of the number of determination values is set to “65536” corresponding to a random number for internal lottery (an integer from 0 to 65535). For this reason, for example, the winning probability of the lottery subject for which “300” is set as the number of determination values is 300/65536.

  12 and 13 show combinations of special combinations that are read as lottery targets for each gaming state, FIG. 14 shows combinations of small roles that are read as lottery targets for each gaming state, and FIG. The combination of the re-games read out as the lottery target game for each game state is shown. FIG. 16 shows combinations of the combinations constituting the simultaneous winning combinations shown in FIGS.

The middle bell 1 is the middle bell + the upper bell 2 + the upper bell 5, the middle bell 2 is the middle bell + the upper bell 1 + the upper bell 6, and the middle bell 3 is the middle bell + the upper bell 4 + the upper bell. 7 and the middle bell 4 is the middle bell + the upper bell 3 + the upper bell 8. The middle bells 1 to 4 are also simply called middle bells. The right bell 1 is the middle bell + the upper bell 3 + the upper bell 5, the right bell 2 is the middle bell + the upper bell 1 + the upper bell 7, and the right bell 3 is the middle bell + the upper bell 4 + the upper bell. 6 and the right bell 4 is the middle bell + the upper bell 2 + the upper bell 8. The right bells 1 to 4 are also simply called right bells. The left bells 1 to 4, the middle bells 1 to 4, and the right bells 1 to 4 are also simply referred to as push order bells.

  The promotion replay is promotion replay 1 + promotion replay 2.

  Replay GR1 is normal replay + promotion replay 1, replay GR2 is normal replay + promotion replay 1 + promotion replay 2, replay GR3 is normal replay + promotion replay 1 + lower replay, and replay GR4. Is normal replay + promotion replay 1 + promotion replay 2 + lower replay, replay GR5 is normal replay + promotion replay 2, and replay GR6 is normal replay + promotion replay 2 + lower replay.

  Replay GR11 is tumble replay + special replay, replay GR12 is tumble replay + special replay + normal replay, replay GR13 is tumble replay + special replay + lower replay, and replay GR14 is Tumble replay + special replay + normal replay + lower replay. Replay GR15 is tumble replay + special replay + promotion replay 1.

  Also, in normal / RT0-3, etc., weak watermelon, strong watermelon, weak cherry, strong cherry, middle cherry, one piece, normal replay, fall replay, promotion that can be elected simultaneously with any of BB1-BB4, RB1, RB2 The number of replay judgment values for internal 1 · RT0 and internal 2 · RT0 is read separately from the bonus, respectively, strong watermelon, weak cherry, strong cherry, middle cherry, single-player, normal replay, falling Since it is added to the replay and the promotion replay, the winning probability of each of the strong watermelon, weak cherry, strong cherry, middle cherries, single combination, normal replay, falling replay, and promoted replay is guaranteed.

  In this way, the internal lottery role varies depending on whether the gaming state is the normal gaming state, 1 or 2 inside, BB (RB), or RB, and BB (RB) In RB, the internal lottery is performed using a lottery table in which the winning probability of the small role is set higher than that in the normal gaming state and inside.

  Also, when the game state is 1 or 2 in the inside, the subject of the internal lottery does not change depending on whether it is 1 in the inside or 2 in the inside, but it is 1 in the inside or inside The internal lottery is performed using a lottery table in which the winning probabilities of the target re-gamer are different.

  In addition, when the gaming state is the normal gaming state, the re-game player to be subject to the internal lottery differs depending on whether it is RT0-3, and depending on whether it is RT0-3 An internal lottery is performed using a lottery table with different re-game players and their winning probabilities.

  In this embodiment, when a plurality of types of re-game players are won at the same time, as shown in FIG. 17, a re-game player determined according to the type of the re-game players won at the same time and the stop operation order is won. Control is performed so that the line is stopped within a maximum of 4 frames on the line. FIG. 17 is a diagram for explaining reel control when a plurality of replays are simultaneously won.

  When the replay GR1 (normal replay + promotion replay 1) is won and a stop operation is performed in the order of left middle right, the combination of the promotion replay 1 among the selected replay players is aligned with the winning line LN and stopped. When the control is performed and the stop operation is performed in an order other than the left middle right, the control is performed so that the combination of the normal replays is aligned with the winning line LN and stopped.

  When replay GR2 (normal replay + promotion replay 1 + promotion replay 2) is won and the stop operation is performed in the order of left and right, the combination of promotion replay 1 among the selected replay players is aligned with the winning line LN Control to stop is performed, and when stop operation is performed in an order other than left and right middle, control is performed to align the combination of normal replays to the winning line LN and stop.

  If Replay GR3 (Normal Replay + Promotion Replay 1 + Lower Replay) is won and the stop operation is performed in the middle left or right order, the combination of Promotion Replay 1 among the selected replay players will be aligned to the winning line LN and stopped. When the stop operation is performed in an order other than middle left and right, control is performed so that the combination of normal replays is aligned with the winning line LN and stopped.

  If Replay GR4 (Normal Replay + Promotion Replay 1 + Promotion Replay 2 + Lower Replay) is won and a stop operation is performed in the middle right / left order, the combination of Promotion Replay 1 among the selected replaying players is placed on the winning line LN When the stop operation is performed in an order other than middle right and left, the control is performed so that the combination of the normal replays is aligned with the winning line LN and stopped.

  When replay GR5 (normal replay + promotion replay 2) is won and stop operation is performed in the order of the middle left and right, the combination of the promotion replay 2 among the selected replay players is stopped in line with the winning line LN When the stop operation is performed in an order other than the middle right and left, control is performed so that the combination of normal replays is aligned with the winning line LN and stopped.

  When Replay GR6 (Normal Replay + Promotion Replay 2 + Lower Replay) is won and the stop operation is performed in the order of middle right and left, the combination of Promotion Replay 2 of the selected replaying players is aligned with the winning line LN Control to stop is performed, and when stop operations are performed in an order other than right center left, control is performed to align the normal replay combination with the winning line LN and stop.

  As shown in FIG. 3, the symbols constituting the promotion replay 1, the promotion replay 2, and the normal replay are arranged at intervals of 5 frames or less on all of the left reel 2L, the middle reel 2C, and the right reel 2R. The reel control is performed so that the promotion replay 1, the promotion replay 2 or the normal replay always wins regardless of the stop operation timing of the stop switches 8L to 8R according to the operation order.

  In this way, different operation modes are set as the operation modes for allowing the replays GR1 to 6 to win the promoted replays 1 and 2.

  Therefore, in the normal / RT1 where the replays GR1 to 6 are the targets of the internal lottery, if any of the replays GR1 to GR6 is elected, the promoted replay wins with a probability of 1/6, and the normal / RT0 Will be migrated.

  When the replay GR11 (falling replay + special replay) is won and the stop operation is performed in the order of left, middle and right, the control of stopping the combination of the special replays in the winning replay combination in the winning line LN. If the stop operation is performed in an order other than the left middle right, control is performed to stop the combination of the fall replays aligned with the winning line LN.

  When replay GR12 (falling replay + special replay + normal replay) is won and the stop operation is performed in the order of left and right, the combination of special replays among the selected replay players is stopped in line with the winning line LN. When the control is performed and the stop operation is performed in an order other than right and left, the control is performed to stop the combination of the fall replays on the winning line LN.

  When replay GR13 (falling replay + special replay + lower replay) is won and a stop operation is performed in the middle / left / right order, the combination of special replays among the selected replay players is aligned with the winning line LN and stopped. When the control is performed and the stop operation is performed in an order other than the middle left and right, the control is performed so that the combination of falling replays is aligned with the winning line LN and stopped.

  If Replay GR14 (Tumble Replay + Special Replay + Normal Replay + Lower Replay) is won and the stop operation is made in the middle right / left order, the combination of special replays among the selected replay players is aligned to the winning line LN If the stop operation is performed in an order other than middle right and left, the combination of falling replays is aligned with the winning line LN and stopped.

  When replay GR15 (falling replay + special replay + promotion replay 1) is won and pressed right, that is, when the stop operation is performed in an operation mode in which the right reel 2R is first stopped, the special replay among the selected replay players When the stop operation is performed in the operation mode in which the combination of the above is aligned with the pay line LN and left-pressed, that is, in the operation mode in which the left reel 2L is first stopped or in the middle mode, that is, in the operation mode in which the middle reel 2C is first stopped. In this case, a control is performed to stop the combination of falling replays in line with the winning line LN.

  As shown in FIG. 3, since the symbols constituting the special replay and the fall replay are arranged at intervals of 5 frames or less in all of the left reel 2L, the middle reel 2C, and the right reel 2R, Regardless of the stop operation timing of the stop switches 8L to 8R, the reel control is performed so that the special replay or the fall replay is always won.

  In this way, different operation modes are set as the operation modes in order to win special replays and avoid falling replays with the replays GR11 to 15.

  For this reason, if one of the replays GR11 to 15 is elected in the normal / RT0 where the replays GR11 to 15 are the targets of the internal lottery, the special replay wins with a probability of 1/5 and shifts to the normal / RT2. On the other hand, the fall replay wins with a probability of 4/5 and shifts to normal RT1.

  Next, when a plurality of types of small combinations are won simultaneously, as shown in FIG. 18, a maximum of 4 small combinations determined according to the types of small combinations that are simultaneously selected and the order of stop operations are displayed on the winning line. Control is performed so as to stop evenly within the frame drawing range. FIG. 18 is a diagram for explaining reel control when a plurality of small combinations are won simultaneously.

  If left bell 1 (lower right bell + upper bell 6 + upper bell 7) wins and the stop operation is performed by pressing to the left, the combination of right down bells of the selected small roles is aligned with the winning line LN and stopped. When the stop operation is performed by middle pressing or right pressing, control is performed so that any combination of the upper bell 6, the upper bell 7, or the transition outcome is aligned with the winning line LN.

  If left bell 2 (lower right bell + upper bell 5 + upper bell 8) is elected and stopped by left-pressing, the combination of right-down bells in the selected small role is aligned with the winning line LN and stopped. When a stop operation is performed by middle pressing or right pressing, control is performed so that any combination of the upper bell 5, the upper bell 6 or the transitional outcome is aligned with the winning line LN.

  If left bell 3 (lower right bell + upper bell 2 + upper bell 3) is elected and the stop operation is performed by pressing the left button, the right falling bell combination of the selected small roles is aligned with the winning line LN and stopped. When the stop operation is performed by middle pressing or right pressing, control is performed such that any combination of the upper bell 2, the upper bell 3, or the transition outcome is aligned with the winning line LN.

  If left bell 4 (lower right bell + upper bell 2 + upper bell 4) is elected and the stop operation is performed by pressing the left button, the combination of the right falling bells of the selected small roles is aligned with the winning line LN and stopped. When the stop operation is performed by middle pressing or right pressing, control is performed so that any combination of the upper bell 2, the upper bell 4, or the transitional outcome is aligned with the winning line LN.

  As shown in FIG. 3, the configuration symbol of the right-down bell is arranged at intervals of 5 frames or less on all reels, and when the left bells 1 to 4 are elected, a stop operation is performed by pushing left. In this case, regardless of the timing of the stop operation, control is always performed so that the right lowering bell is aligned with the winning line LN, while the symbols constituting the upper bells 1 to 8 are at intervals of 5 frames or more on all reels. Even if the left bells 1 to 4 are elected because there are places that are arranged, if the stop operation is performed by pressing the middle or right, it becomes the drawing range of the constituent symbols of the elected upper bells 1 to 8 If the stop operation is not performed at an appropriate timing, the winning upper bell cannot be aligned with the winning line LN, and in this case, the control is performed so that the transition outcome is aligned with the winning line LN.

  When middle bell 1 (middle bell + upper bell 2 + upper bell 5) is elected and the stop operation is performed by pressing the middle bell, the control of stopping the combination of the middle bells of the elected small roles with the winning line LN is stopped. If a stop operation is performed by left-pressing or right-pressing, control is performed so that any combination of the upper bell 2, the upper bell 5, or the transition outcome is aligned with the winning line LN.

  When middle bell 2 (middle bell + upper bell 1 + upper bell 6) is elected and the stop operation is performed by pressing the middle bell, the control of stopping the combination of the middle bells of the elected small roles with the winning line LN is stopped. If the stop operation is performed by pressing left or right, control is performed so that any combination of the upper bell 1, the upper bell 6, or the transition outcome is aligned with the winning line LN.

  When middle bell 3 (middle bell + upper bell 4 + upper bell 7) is elected and the stop operation is performed by pressing the middle bell, the control of stopping the combination of the middle bells of the elected small roles on the winning line LN is stopped. If a stop operation is performed by left-pressing or right-pressing, control is performed so that any combination of the upper bell 4, the upper bell 7, or the transition outcome is aligned with the winning line LN.

  When middle bell 4 (middle bell + upper bell 3 + upper bell 8) is elected and the stop operation is performed by pressing the middle bell, the control of stopping the combination of the middle bells of the elected small roles on the winning line LN is stopped. If a stop operation is performed by left-pressing or right-pressing, control is performed so that any combination of the upper bell 3, the upper bell 8, or the transition outcome is aligned with the winning line LN and stopped.

  As shown in FIG. 3, the configuration symbols of the middle bell are arranged at intervals of 5 frames or less on all reels, and when the middle bell 1 to 4 is elected, when the stop operation is performed by middle push Regardless of the timing of the stop operation, control is always performed so that the middle bell is aligned with the winning line LN, while the symbols constituting the upper bells 1 to 8 are arranged at intervals of 5 frames or more on all reels. Even if the middle bells 1 to 4 are elected, if the stop operation is performed by pressing left or right, an appropriate range that will be drawn in the constituent symbols of the elected upper bells 1 to 8 will be used. If the stop operation is not performed at the timing, the selected upper bell cannot be aligned with the winning line LN, and in this case, control is performed so that the shift outcome is aligned with the winning line LN.

  When right bell 1 (middle bell + upper bell 3 + upper bell 5) is elected and the stop operation is performed by pressing right, the combination of middle bells of the selected small roles is stopped in alignment with the winning line LN. When a stop operation is performed by left-pressing or middle-pressing, control is performed so that any combination of the upper bell 3, the upper bell 5, or the transition outcome is aligned with the winning line LN and stopped.

  When right bell 2 (middle bell + upper bell 1 + upper bell 7) is elected and the stop operation is performed by pressing right, the combination of middle bells among the selected small roles is stopped in line with the winning line LN. When a stop operation is performed by left-pressing or middle-pressing, control is performed so that any combination of the upper bell 1, the upper bell 7, or the transition outcome is aligned with the winning line LN.

  When right bell 3 (middle bell + upper bell 4 + upper bell 6) is elected and a stop operation is performed by pressing right, the combination of middle bells among the selected small roles is stopped in alignment with winning line LN. When a stop operation is performed by left-pressing or middle-pressing, control is performed so that any combination of the upper bell 4, the upper bell 6, or the transitional outcome is aligned with the winning line LN.

  When right bell 4 (middle bell + upper bell 2 + upper bell 8) is elected and the stop operation is performed by pressing right, the combination of middle bells of the selected small roles is stopped in alignment with winning line LN. When a stop operation is performed by left-pressing or middle-pressing, control is performed so that any combination of the upper bell 2, the upper bell 8, or the transition outcome is aligned with the winning line LN.

  As shown in FIG. 3, the configuration symbols of the middle bell are arranged at intervals of 5 frames or less on all reels, and when the right bell 1 to 4 is elected, when the stop operation is performed by pushing right However, regardless of the timing of the stop operation, control is always performed so that the middle bell is aligned with the winning line LN, while the symbols constituting the upper bells 1 to 8 are arranged at intervals of 5 frames or more on all reels. Therefore, even if the right bells 1 to 4 are elected, if the stop operation is performed by left-pressing or middle-pressing, an appropriate drawing range of the constituent symbols of the elected upper bells 1 to 8 is appropriate. If the stop operation is not performed at the timing, the selected upper bell cannot be aligned with the winning line LN, and in this case, control is performed so that the shift outcome is aligned with the winning line LN.

  Thus, in this embodiment, when any of the left bell, middle bell, right bell, that is, the push order bell is won, by performing a stop operation in a specific operation mode according to the type of winning combination, While the right-down bell or middle bell always wins, if the stop operation is performed in an operation mode other than the specific operation mode according to the type of winning combination, the upper bell is aligned at 1/4, but at 3/4 In some cases, the upper bells are not aligned and the transition outcomes are aligned.

  For this reason, at the time of winning the push order bell, the expected value of the number of medals to be paid out can be changed depending on whether or not it is operated in a specific operation mode according to the type of winning combination. In other words, even if one of the push order bells is won, it is impossible to intentionally select a specific operation mode unless the type is known. Although a medal can be surely obtained by winning a prize, the upper bell can be won only by 1/4 at a ratio of 2/3, and a medal cannot be surely obtained.

  Although not particularly shown, when a bell (middle bell + lower right bell) is won, a combination of “bell-bell-bell” is arranged on the winning line LN regardless of the stop order of the reels and the operation timing. To be controlled.

  In this embodiment, as shown in FIG. 10 and FIG. 11, it is controlled to one of the normal gaming state, the inside 1, the inside 2, RB, BB (RB), and in the normal gaming state, RT 0 to 3. It is controlled by either.

  As described above, the RAM 507 of the main control unit 41 is assigned with an area for storing a gaming state flag that can specify a gaming state and an area for storing an RT flag that can specify an RT type. Yes. The gaming state flag is 4-bit data, 0000 indicates the normal gaming state, 0001 indicates the internal one, 0010 indicates the internal two, 0100 indicates the RB, and 1100 indicates the BB (RB). . The RT flag is 4-bit data. 0000 indicates RT0, 0001 indicates RT1, 0010 indicates RT2, 0011 indicates RT3, and 0100 indicates RT4.

  As shown in FIG. 11, when the value of the game state flag is 0000 and the value of the RT flag is 0000, it indicates that the game state flag is RT0, the game state flag value is 0000, and the RT flag value is 0001. In this case, it indicates that the normal gaming state is RT1, and when the gaming state flag value is 0000 and the RT flag value is 0010, it indicates that the normal gaming state is RT2, and the gaming state flag value is When the value of 0000 and RT flag is 0011, it indicates that the game state is normal and RT3, and when the value of game state flag is 0001 and the value of RT flag is 0000, it indicates that it is 1 inside. When the value of the game state flag is 0010 and the value of the RT flag is 0000, it indicates that the inside is 2, the value of the game state flag is 0100, and the value of the RT flag is 00. 0, indicates a RB, when the value of the gaming state flag is the value of 1100, RT flag 0000 indicates a BB (RB).

  On the other hand, in the present embodiment, as the lottery table in which the number of determination values for the target combination is determined, the lottery table for internal one, the lottery table for internal two, the lottery table for RB, and the lottery for BB (RB) Each having a table and a lottery table for a normal gaming state, and further, as a lottery table for a normal gaming state, a lottery table for RT0, a lottery table for RT1, a lottery table for RT2, and a lottery table for RT3 Each has.

  In the internal lottery process, the gaming state flag and the RT flag value stored in the RAM 507 are referred to identify the gaming state and the RT type, select the lottery table accordingly, and select the selected lottery table. By using the lottery, the lottery subject according to the gaming state and the type of RT is drawn with a winning probability according to the gaming state and the type of RT.

  Normal / RT0 is normal / RT1 when a promotion replay wins (when either one of the replays GR1 to GR6 is elected and a stop operation is performed in the order in which the promotion replay wins), normal / RT1 or normal / RT2 Shifts when the game is completed due to the consumption of the specified number of games. At this time, the value of the gaming state flag does not change from 0000 indicating the normal gaming state, and the value of the RT flag is updated to 0000 indicating RT0. Regardless of the number of games after the transition to normal / RT0, the normal / RT0 shifts to the normal / RT1 by winning the fall replay or stopping the transition, or to the normal / RT2 by winning the special replay It ends when the special role is elected and moves to the inside 1 or inside 2 inside.

  Usually, the winning probability for special roles in RT0 is normal (about 1/239), the winning probability for replaying roles is high (about 1 / 1.4), and the winning probability for small roles is normal (about 1 / 3.5) However, the winning probability is about 1 / 6.1), and the payout rate of medals per game is 1 or more. Moreover, in normal / RT0, except for the case where the winning combination is made at the same time as the special combination, only the replay GRs 11 to 15 among the re-playing combinations are targeted for the internal lottery.

  The normal / RT1 shifts when the transition is stopped at the normal / RT0, the normal / RT2, and the normal / RT3, or when the fall replay wins at the normal / RT0. At this time, the value of the gaming state flag does not change from 0000 indicating the normal gaming state, and the value of the RT flag is updated to 0001 indicating RT1. Then, the normal RT1 ends when the promotion replay wins and then shifts to the normal RT0, or when the special role is elected and shifts to the inside 1 or the inside 2.

  Normal / RT1 special role win probability is normal (approx. 1/239), same as RT0, re-game player win probability is lower than normal / RT0 normal (approx. 1 / 7.3), small role win The probability is normal (normally about 1 / 3.5, but the winning probability is about 1 / 6.1) like RT0, and the payout rate of medals per game is less than 1. Further, in normal / RT1, only normal replay and replay GR1 to replay GR1 to 6 are included in the internal lottery.

  Normal / RT2 shifts when special replay wins in normal / RT0. At this time, the value of the gaming state flag does not change from 0000 indicating the normal gaming state, and the value of the RT flag is updated to 0010 indicating RT2. Then, the normal / RT2 is terminated when the transition is stopped and the normal / RT1 is transferred to the normal / RT1 or the special combination is elected and the internal / external 1 or internal 2 is transferred.

  Normal / RT2 special role win probability is normal (approx. 1/239), same as RT0, re-game player win probability is almost the same as RT (0), high probability (approx. 1 / 1.4), small The winning probability of the combination is normal (normally about 1 / 3.5, but the winning probability is about 1 / 6.1) as with RT0, and the payout rate of medals per game is 1 or more. Also, in normal / RT2, only the normal replay among the replaying combinations is subject to the internal lottery, except when winning at the same time as the special combination.

  Normally, RT3 shifts to the end of BB (RB) and RB. At this time, the value of the gaming state flag does not change from 0000 indicating the normal gaming state, and the value of the RT flag is updated to 0011 indicating RT3. Regardless of the number of games since the transition to the normal / RT3, the normal / RT3 stops the transition and moves to the RT1, or the special role is elected and moves to the internal 1 or the internal 2 To finish.

  The winning probability of special roles in normal / RT3 is normal (about 1/239), the winning probability of replaying roles is normal / normally lower than RT0 (about 1 / 7.3), and the winning probability of small roles is normal / RT0 As usual, it is normal (about 1 / 3.5, but the winning probability is about 1 / 6.1), and the payout rate of medals per game is less than 1. Moreover, in normal / RT3, except for the case where the winning combination is won at the same time as the special combination, only the normal replay out of the re-playing combination is subject to the internal lottery.

  The inside 1 shifts when BB1, BB3, RB2 among the special roles are won in the normal gaming state. At this time, the value of the game state flag is updated to 0001 indicating internal 1 and the value of the RT flag is updated to 0000 indicating RT0. Then, regardless of the number of games since the transition to the inside, the inside 1 finishes when the special role that triggered the transition to the inside 1 wins and shifts to BB (RB) or RB. .

  In the inside 1, the special role is excluded from the internal lottery, and the winning probability of the re-playing role is lower than normal RT0, normal RT2, but higher than normal RT1, normal RT3, and high probability (about 1 /4.2), the winning probability of a small role is normal (about 1 / 3.5, but the winning probability is about 1 / 6.1), and the payout rate of medals per game is less than 1. Moreover, in the inside 1, only the normal replay and the lower replay among the re-game players are targeted for the internal lottery.

  The inside 2 shifts when BB2, BB4, RB1 among special roles are won in the normal gaming state. At this time, the value of the game state flag is updated to 0010 indicating 2 inside, and the value of the RT flag is updated to 0000 indicating RT0. Then, inside 2 ends regardless of the number of games since the transition to the inside, when the special combination that triggered the transition to the inside 2 wins and shifts to BB (RB) or RB. .

  In internal 2, the special role is not subject to internal lottery, and the winning probability of replaying is lower than normal · RT0, normal · RT2, but higher than normal · RT1, normal · RT3, internal 1 Probability (approx. 1 / 2.9), probability of winning a small role is normal (approx. 1 / 3.5, but winning probability is approx. 1 / 6.1), and medal payout rate per game is less than 1. It becomes. Further, in the inside 2, only the normal replay and the lower replay among the re-game players are targeted for the internal lottery.

  RB shifts when RB1 or RB2 wins in 1 and 2 inside. At this time, the value of the gaming state flag is updated to 0100 indicating RB, and the value of the RT flag does not change from 0000 indicating RT (0). And RB is complete | finished by digesting 12 games or winning 6 times.

  In RB, the special role and re-playing role are not subject to internal lottery, and the winning probability of the small role is higher than normal 1 and 2 in the normal gaming state, high probability (about 1 / 1.01), The payout rate of medals per game is 1 or more.

  BB (RB) shifts when BB wins inside. At this time, the value of the game state flag is updated to 1100 indicating BB (RB), and the value of the RT flag does not change from 0000 indicating RT (0). Then, BB (RB) ends when the total number of medals paid out to BB (RB) exceeds the prescribed number, regardless of the number of games since the transition to BB (RB).

  In BB (RB), special roles and re-playing roles are not subject to internal lottery, and the winning probability of small roles is higher than the normal gaming state, 1 or 2 inside, and high probability (about 1 / 1.00) The medal payout rate per game is 1 or more.

  Among the normal gaming state, 1, 2, RB, and BB (RB), RB and BB (RB) are the most advantageous gaming states with the highest medal payout rate per game.

  RT0 and RT0 of RT0 and 3 in the normal gaming state have a high probability of winning a re-gamer and the payout rate of medals per game is higher than RT1 and RT3. It can be said that it is a more advantageous state for the player.

  Further, in the slot machine according to the present embodiment, when the gaming state is RT0 to 3, the sub-control unit 91 provides an assist time (hereinafter referred to as AT) that is a notification period in which a navigation effect that notifies the internal lottery result can be executed. The production state can be controlled.

  Here, the gaming state and the transition state of RT will be described. As shown in FIG. 10, when RB or BB (RB) ends, the routine shifts to normal RT3.

  In normal / RT3, when the transition outcome is stopped, the transition is made to RT1, and when the special role is elected, transition is made to internal 1 or internal 2 according to the type of the special role won.

  In normal / RT3, if any of the left bells 1-4, middle bells 1-4, right bells 1-4 wins, and the small part cannot be won, the transition will stop. Therefore, any of the left bell 1-4, the middle bell 1-4, the right bell 1-4 can be won and the small role can be won in the normal RT 4 which has been shifted to after the end of RB or BB (RB) If not, the process moves to normal RT1.

  In normal / RT1, the game proceeds to normal / RT0 when the promotion replay wins, and when the special role is won, it shifts to internal 1 or internal 2 depending on the type of the special role selected.

  Usually ・ Replay GR1-6 wins in RT1, and the promotion replay wins when the stop order is correct. Therefore, in normal ・ RT1, replay GR1-6 wins and corrects in the order of stop. It will shift to RT0.

  In normal / RT0, if the fall replay wins, or if the transition is stopped, it moves to normal / RT1, and if the special replay wins, it moves to normal / RT2, and the special role is won. Depending on the type of the special role, it shifts to 1 inside or 2 inside.

  Usually, the replays GR11 to 15 are elected at RT0, the special replay is won when the stop order is correct, and the fall replay is won when the answer is incorrect. In addition, in the case of normal / RT0, when any one of the left bells 1 to 4, the middle bells 1 to 4 and the right bells 1 to 4 is won and the small role cannot be won, the transitional outcome stops. For this reason, in normal / RT0, the replay GRs 11 to 15 are elected and the stop order is correct, so that the normal / RT2 is entered, and the replay GRs 11 to 15 are elected and the stop order is incorrect or the left bell 1 -4, middle bell 1 to 4, right bell 1 to 4 are elected, and if it is not possible to win a small role, it will shift to normal · RT1.

  In normal / RT2, when the special role is elected, it shifts to the inside 1 or the inside 2 according to the type of the won special role.

  In normal / RT2, when any one of the left bell 1 to 4, the middle bell 1 to 4 and the right bell 1 to 4 wins and the small role cannot be won, the transitional outcome stops. For this reason, in normal / RT2, if any of left bell 1-4, middle bell 1-4, and right bell 1-4 is won and the small role cannot be won, the routine proceeds to normal / RT1. It will be.

  In the inside 1 and 2, the special role that triggers the transition to the inside wins a transition to RB or BB (RB).

  The sub-control unit 91 performs an AT lottery to determine whether or not to control to an AT (assist time), which will be described later, by executing an AT lottery process. In the AT lottery process, it is determined whether or not a predetermined lottery condition is satisfied based on a command from the main control unit 41, and the AT lottery is executed when the predetermined lottery condition is satisfied.

  In addition, when it is determined that the AT is controlled in the AT lottery, the sub-control unit 91 controls the added state, which will be described later, and also controls the AT after the added state ends.

  Specifically, the sub-control unit 91 wins the replay GR 1 to 6 that can be shifted to the normal / RT0 when the AT lottery is won in the normal / RT1, and the promoted replay wins the normal / RT0. In the period up to the transition, it is controlled to the added state, and in this state, the promotion replay wins and shifts to normal / RT0, the added state ends, AT control starts, and the navigation effect can be executed. . At this time, as described later, in normal / RT0, when the replays GR11 to 15 are won, the navigation effect is targeted, and in the navigation effect, the push order for winning the special replay when the replays GR11 to 15 are won is notified. Then, it is possible to shift from normal RT0 to RT2 by performing a stop operation in accordance with the notified pressing order.

  When it is controlled by the AT and when the normal / RT0 is shifted to the normal / RT2, the start condition for counting the number of AT games is satisfied, and until the number of AT games determined in the added state is consumed. Then, the RT is controlled to an ART that is an RT and an AT having a high winning probability of the re-gamer. During this time, if it is normal / RT0 as will be described later, it will be the target of navigation effect when the replays GR11 to 15 are selected, and the push order bell will be the target of navigation effect regardless of normal / RT0, normal / RT2. In the navigation effect, in the normal / RT0, the push order for winning the special replay is notified when the replays GR11 to 15 are selected, so the stop operation is performed according to the notified push order to change from the normal / RT0 to the normal / RT1. It is possible to shift to normal / RT2 without shifting. Also, in both normal / RT0 and normal / RT2, when the push order bell is won, the transition outcome is avoided and the push order for winning the bell is notified, so by performing the stop operation according to the notified push order It is possible to acquire medals without shifting from normal RT0 or normal RT2 to normal RT1.

  At the end of the added state, the sub-control unit 91 adds the number of added games won in the added lottery executed in the added state and the minimum guaranteed number of games (10 games in this embodiment) as the number of AT games. The data is stored in a predetermined area of the RAM 91c. The sub-control unit 91 controls to AT during a period until the number of AT games in the RAM 91c becomes zero. When the number of games remains and the target role of navigation is won, a navigation effect is executed.

  Further, the sub-control unit 91 controls to be non-AT when the remaining number of games is 0 in ART. When controlled to non-AT, the navigation effect is not executed. Thereby, when it is normal / RT2, there is a higher possibility that the transition outcomes are aligned, and there is a higher possibility of being controlled to normal / RT1 which is disadvantageous for the player as compared to normal / RT2.

  If the sub-control unit 91 is controlled by the AT, the sub-control unit 91 performs a navigation effect by winning the navigation target combination corresponding to the gaming state. The navigation target combination corresponding to the game state is replay GR1-6 when it is normal / RT1, and replay GR11-15 when it is normal / RT0. Further, in normal and RT0 to 2, the push order bell is a common navigation target combination.

  As a navigation effect when winning replays GR1 to GR6, a push order (see FIG. 17) for winning a promotion replay according to the winning situation is notified. For example, a message such as “left middle right!” Is displayed on the liquid crystal display 51 as a navigation effect when winning the replay GR1. In addition, as a navigation effect when winning the replay GR2, a message such as “middle left and right!” Is displayed on the liquid crystal display 51. Further, as a navigation effect when the replay GR3 is won, a message such as “middle left and right!” Is displayed on the liquid crystal display 51. Further, as a navigation effect when the replay GR 4 is won, a message such as “middle right left!” Is displayed on the liquid crystal display 51. Further, as a navigation effect when winning the replay GR5, a message such as “middle right!” Is displayed on the liquid crystal display 51. Further, as a navigation effect when the replay GR 6 is won, a message such as “Right Middle Left!” Is displayed on the liquid crystal display 51.

  As a navigation effect when the replays GR11 to 15 are won, a push order (see FIG. 17) for winning a special replay according to the winning situation is notified. For example, a message such as “left middle right!” Is displayed on the liquid crystal display 51 as a navigation effect when winning the replay GR11. Further, as a navigation effect when winning the replay GR 12, a message such as “Middle right and left!” Is displayed on the liquid crystal display 51. Further, as a navigation effect when winning the replay GR 13, a message such as “middle left and right!” Is displayed on the liquid crystal display 51. Further, as a navigation effect when winning the replay GR 14, a message such as “middle right left!” Is displayed on the liquid crystal display 51. Further, as a navigation effect when the replay GR 15 is won, a message such as “Right!” Is displayed on the liquid crystal display 51.

  Further, as a navigation effect when one of the push order bells is won, a push order (see FIG. 18) for surely winning a right-down bell or a middle bell is notified. For example, when winning the left bell, the left reel is stopped as the first stop reel, so that the right falling bell can be reliably won, so “left!” For stopping the left reel as the first stop reel. Is displayed on the liquid crystal display 51. In addition, when the middle bell is won, the middle bell can be surely won by stopping the middle reel as the first stop reel, so “medium!” For stopping the middle reel as the first stop reel. A message is displayed on the liquid crystal display 51. Also, when the right bell is won, the middle bell can be reliably won by stopping the right reel as the first stop reel, so “right!” For stopping the right reel as the first stop reel. A message is displayed on the liquid crystal display 51.

  As described above, in the navigation effect in the present embodiment, a message reminiscent of an operation mode advantageous to the player is notified in the same mode regardless of the type of the navigation target role. For this reason, the player can operate in an operation mode that is advantageous to the player without being conscious of the type of the winning navigation target combination.

  In addition, the aspect of a navigation effect is not restricted to such an aspect, What kind of thing may be sufficient if a player is distinguishable according to a winning condition. In addition, the navigation effect is not limited to what is displayed on the liquid crystal display 51, and may be executed using the effect effect LED 52, the speakers 53 and 54, the reel LED 55, and the like.

  Then, by executing the navigation effect, it is possible to avoid the promotion replay winning, the special replay winning, and the bell winning that are intentionally won, the fall replay winning, and the stop of the transitional outcome.

  Next, the flow from the time of AT winning to the start of AT will be described based on FIG.

  First, when the AT is won, the sub-control unit 91 shifts from the normal / RT1 and non-AT state (hereinafter referred to as the normal state) to the added state. In each game in the added state, it is determined whether or not the target role to be added has been won. If the target role to be added is selected, a lottery is performed with a probability corresponding to the selected target role to be added. . The extra lottery is a lottery in which the number of extra games (the number of games added to a minimum guaranteed game described later) is determined from a plurality of predetermined games, and the number of extra games won is accumulated. ing.

  Further, in each game in the added state, it is determined whether or not the replays GR1 to GR6 are won.

  When replays GR1 to GR6 are elected, whether to start AT based on the current number of added games (whether to promote promotion replay), or to invalidate the current number of added games and continue the added state ( If you choose to start AT based on the current number of additional games based on the player's operation (if promotion replay wins), the minimum is The sum of the guaranteed number of games (10 games in this embodiment) and the number of added games accumulated in the added state is set in the RAM 91c as the number of AT games, and AT is started.

  On the other hand, if it is selected that the current number of added games is invalid and the added state is to be continued (if the promotion replay has not won a prize), the number of times the continuation of the added state from the start of the added state is selected. It is determined whether or not the specified number of times (in this example, two times) has been reached, and if the number of times the continuation of the added state has been selected from the start of the added state has reached the specified number of times, the minimum guarantee The sum of the number of games (10 games in this embodiment) and the number of added games accumulated in the added state is set in the RAM 91c as the number of AT games, and AT is started. In this case, since it is normal / RT1, the next replay GR1 to 6 is elected, and the AT starts when the promotion replay wins.

  In addition, if the number of times of selecting the continuation of the added state from the start of the added state has not reached the specified number, the number of selected continuations of the added state is incremented by 1 and the accumulated number of added games is cleared and added. The state is continued, and the number of additional games is accumulated again each time the additional target combination is won during this period.

  As described above, the sub-control unit 91 according to the present embodiment performs an extra lottery that determines the number of extra games with a probability determined according to the extra target role when the extra target role is won in the internal lottery in the extra state. .

  As shown in FIG. 20, if the winning combination is a push order bell, the number of additional games is determined to be 10 games at a rate of 50%, and the number of additional games is determined to be 30 games with a probability of 30%.

The number of additional games is determined to be 250 games with a probability of%, and the number of additional games is drawn so that the number of additional games is determined to be 300 games with a probability of 3%, and is acquired by one additional lottery. The average number of additional games that can be expected is 52.5 games.

  If the winning role is a single bell, the additional game number is determined to be 10 games with a probability of 30%, the additional game number is determined to be 30 games with a probability of 15%, and the additional game number is 50 games with a probability of 40%. 3% of the number of additional games is determined to be 100 games, 3% of the number of additional games is determined to be 150 games, and 3% of the number of additional games is determined to be 200 games. The number of additional games is determined to be 250 games with a probability of%, and the number of additional games is drawn so that the number of additional games is determined to be 300 games with a probability of 3%, and is acquired by one additional lottery. The average number of games that can be expected is 57.5 games.

  If the winning combination is one, the number of additional games is determined to be 50 games with a probability of 75%, the number of additional games is determined to be 100 games with a probability of 5%, and the number of additional games is 150 with a probability of 5%. The game is determined, the number of additional games is determined to be 200 games with a probability of 5%, the number of additional games is determined to be 250 games with a probability of 5%, and the number of additional games is determined to 300 games with a probability of 5% In this way, the number of additional games is drawn, and the average number of additional games that can be expected to be acquired in one additional lottery is 87.5 games.

  If the winning role is a weak watermelon, the number of additional games is determined to be 10 games with a probability of 40%, the number of additional games is determined to be 30 games with a probability of 30%, and the number of additional games is 50 games with a probability of 15% 3% of the number of additional games is determined to be 100 games, 3% of the number of additional games is determined to be 150 games, and 3% of the number of additional games is determined to be 200 games. The number of additional games is determined to be 250 games with a probability of%, and the number of additional games is drawn so that the number of additional games is determined to be 300 games with a probability of 3%, and is acquired by one additional lottery. The average number of games that can be expected is 50.5 games.

  If the winning role is strong watermelon, the number of additional games is determined to be 50 games with a probability of 85%, the number of additional games is determined to be 100 games with a probability of 3%, and the number of additional games is 150 games with a probability of 3% 3% probability is added to 200 games, 3% probability is added to 250 games, and 3% probability is added to 300 games. The average number of extra games that can be expected to be obtained in one extra lottery is 72.5 games.

  If the winning role is a weak cherry, the number of additional games is determined to be 10 games with a probability of 40%, the number of additional games is determined to be 30 games with a probability of 30%, and the number of additional games is 50 games with a probability of 15%. 3% of the number of additional games is determined to be 100 games, 3% of the number of additional games is determined to be 150 games, and 3% of the number of additional games is determined to be 200 games. The number of additional games is determined to be 250 games with a probability of%, and the number of additional games is drawn so that the number of additional games is determined to be 300 games with a probability of 3%, and is acquired by one additional lottery. The average number of games that can be expected is 50.5 games.

  If the winning role is a strong cherry, the number of additional games is determined to be 50 games with a probability of 85%, the number of additional games is determined to be 100 games with a probability of 3%, and the number of additional games is 150 games with a probability of 3%. 3% probability is added to 200 games, 3% probability is added to 250 games, and 3% probability is added to 300 games. The average number of extra games that can be expected to be obtained in one extra lottery is 72.5 games.

  If the winning role is an interrupted cherry, the number of additional games is determined to be 50 games with a probability of 75%, the number of additional games is determined to be 100 games with a probability of 5%, and the number of additional games is 150 games with a probability of 5%.

The average number of extra games that can be expected to be obtained in one extra lottery is 87.5 games.

  As described above, in the extra lottery, the number of extra games of 10 games, 30 games, 50 games, 100 games, 150 games, 200 games, 250 games, and 300 games is determined in accordance with the type of the subject to be added. It becomes.

  In particular, when winning a single role, strong watermelon, strong cherry, or middle tier cherry, there will always be an additional 50 games or more, so the display mode that suggests these roles will help AT for a longer period of time. You can expect to be controlled.

  The sub-control unit 91 executes an extra effect in the extra state. In the extra effect, as shown in FIGS. 21A to 21C, an extra zone screen indicating that the superposition state is controlled is displayed on the liquid crystal display 51 with the start of the extra state. On the additional zone screen, the “cumulative value of the number of additional games at the current time”, “the remaining number of times that the continuation of the additional state can be selected”, the invalidated “previous number of additional games”, the invalidated “previous extra number of games” “Number of games” (only when continuation of the added state is selected) is displayed.

  In addition, on the additional zone screen, the cumulative value of the number of additional games at the current time is displayed as a numerical value (for example, +30). For example, the cumulative value of the number of additional games at the present time may be notified based on, for example, a meter display, the number of lit LEDs, or a difference in BGM. Further, although the notification is made in a state in which the cumulative value of the number of added games is added up, a configuration in which the cumulative value of the number of added games can be specified by displaying the added number of games without adding up may be used.

  In addition, on the extra zone screen, the remaining number that can be selected to continue the added state is displayed as a numerical value (for example, two more times), but the remaining number that can be selected to continue the added state is specified. Any mode may be used as long as it can be notified, and for example, the remaining number of times that the continuation of the added state can be selected may be notified by a difference in meter display, the number of lit LEDs, BGM, or the like.

  On the extra zone screen, the number of previous added games that were invalidated and the number of added games that were invalidated the previous time are displayed as numerical values (for example, +30). Any mode may be used as long as the number can be specified, and for example, the number of games added in the previous time may be notified based on a difference in meter display, LED lighting number, BGM, or the like.

  After the start of the extra state, before the replays GR1 to 6 are elected, if an additional target role is won, an extra lottery will be performed, and the number of extra games won in the extra lottery will be added to the “cumulative value of the number of extra games at the present” Is displayed. After that, when the replays GR1 to GR6 are elected, the AT is started based on the cumulative value of the number of added games at the current time (whether the promotion replay is won), or the cumulative value of the current number of added games is invalidated and the added state is continued. A selection screen that prompts the user to select whether or not to promote the promotion replay is displayed.

  In this selection screen, in addition to displaying “cumulative value of the number of additional games at the present time” and “remaining number of times the continuation of the additional state can be selected”, the stop order for starting AT (for promoting a promotion replay) The reels to be stopped first in the (stop order) and the reels to be stopped first in the stop order in which the current number of added games is invalidated and the added state is continued (stop order in which no promotion replay is awarded) are displayed.

  In this state, when the reel stop operation to be stopped first is performed in the stop order (stop order in which the promoted replay is not awarded) in which the current added game number is invalidated and the added state is continued, the promoted replay is not won, While normal / RT1 is maintained, the number of added games accumulated so far is cleared, and the added state continues. Accordingly, as shown in FIG. 21B, the “cumulative value of the number of added games at the present time” is updated to 0 on the added zone screen, and the accumulated value of the number of added games that has been invalidated is changed to “previous time”. “Number of extra games” is displayed, and “remaining number of times the continuation of the additional state can be selected” is displayed by one subtraction.

  In addition, when a reel stop operation to be stopped first is performed in a stop order for starting AT (stop order for winning a promotion replay), a second stop reel for winning a promotion replay and The third stop reel is informed, and the promotion replay is won by performing stop operations in the order in accordance with this, and the game proceeds to normal / RT0, and the accumulated additional game number is added to the minimum guaranteed game number (10 games). An AT start screen indicating that the AT of the added number of AT games starts is displayed, and AT control is started.

  Even in the added state after selecting continuation, an additional lottery will be performed if the additional target role is won before the replays GR 1 to 6 are won, and the number of added games won in the additional lottery will be “cumulative number of added games at the present time” "Value" is displayed in addition. Thereafter, when the replays GR1 to GR6 are won, the above-described selection screen is displayed.

  In this state, when the reel stop operation to be stopped first is performed in the stop order (stop order in which the promoted replay is not awarded) in which the current added game number is invalidated and the added state is continued, the promoted replay is not won, While normal / RT1 is maintained, the number of added games accumulated so far is cleared and the added state continues, and as shown in FIG. 21 (c), in the added zone screen, The “cumulative value of the number of added games at the current time” is updated to 0, the cumulative value of the number of added games that has been invalidated this time is displayed as “the number of added games last time”, and the “remaining number of times that the continuation of the added state can be selected” "Is displayed with 1 subtraction. At this time, if the number of previous added games that have been invalidated is displayed in the “last added number of games”, the value displayed in the “last added number of games” is set to “the number of added games last time”. At the same time, the cumulative value of the number of added games invalidated this time is displayed as “the number of added games last time”.

  In addition, when a reel stop operation to be stopped first is performed in a stop order for starting AT (stop order for winning a promotion replay), a second stop reel for winning a promotion replay and The third stop reel is informed, and the stop replay is performed in the order in accordance with this, and the promoted replay wins. The game proceeds to normal / RT0 and the number of additional games accumulated this time to the minimum guaranteed number of games (10 games). An AT start screen is displayed indicating that the AT for the number of AT games to which is added starts, and AT control is started.

  In addition, when the replays GR1 to 6 are selected in the added state and the remaining number of times that the continuation of the added state can be selected is 0, the selection screen shown in FIG. 21C is used instead of the selection screen described above. In addition, only the reels that should be stopped first in the stop order for starting AT (stop order for winning the promotion replay) are notified, and it is suggested that no further continuation of the added state can be selected. It has become.

  As described above, in this embodiment, the player can select whether to start AT based on the current number of added games or to continue the added state with the current added number of games being invalid. It is possible to obtain an opportunity to increase the number of added games from the present while taking the risk that the number of added games will be smaller than the present by redoing.

  Also, in this embodiment, after the AT starts, if the special role is elected before the number of AT games becomes 0, the AT game number is stopped at that time, the AT is interrupted, and the special game is interrupted. After completing the bonus accompanying the winning of the role, after passing through normal · RT3, normal · RT1, the promotion replay wins again and shifts to normal · RT0, and the special replay wins and shifts to normal · RT2, The counting of the number of AT games is resumed.

  At this time, the normal / RT1 and normal / RT0 are routed before returning to the AT. However, in the normal / RT1, it is controlled to the added state as in the case of winning the AT. It is possible to expect the addition of the number of additional games to the number of remaining AT games.

  As described above, in the slot machine 1 according to the present embodiment, after winning the AT, before the shift to the AT, it is controlled to the added state, and in this added state, the target role of the added lottery (the added target role) ) Is won, and after the completion of the added state, the game shifts to AT, and AT is added over the number of AT games that is the sum of the number of added games and the minimum guaranteed number of games won in the added lottery during the added state. To be controlled. That is, in the added state, the number of AT games of the AT to be transferred thereafter is determined according to the result of the added lottery performed during that time.

  In addition, the added state is terminated when one of the replays GR1 to GR6, which is a condition for transitioning to normal / RT1, is won, and the promoted replay wins and transitions to normal / RT1, and then shifts to AT. However, every time one of the replays GR1 to GR6 wins in the added state, both the stop order in which the promoted replay is won and transferred to the AT, and the stop order in which the added state is continued without promoting the promoted replay are presented. Prompts the user to select whether to start AT based on the current number of added games or to continue the added state by invalidating the current number of added games, that is, the number of added games displayed on the screen of the liquid crystal display 51 If the player chooses the stop order to win the promotion replay and move to AT, the promotion replay wins and goes to normal / RT0, and then -If AT starts by moving to RT2, but the player chooses the stop order to continue the added state without winning the promotion replay, the number of added games accumulated so far will be invalidated and added The state is continued until one of the next replays GR1 to GR6 wins.

  For this reason, the player can select whether to shift to AT based on the number of added games accumulated in the added state, or to invalidate the accumulated number of added games and continue the added state. While taking the risk that the number of games to be added will be smaller than the current number, an opportunity to acquire more games than the current number can be obtained.

  Further, in this embodiment, after the AT is won, it is controlled to be added in a period until one of the replays GR1 to GR6 wins in normal / RT1, that is, a period in which the payout rate of medals per game is less than 1. By extending the added state, it is possible to prevent the player from gaining an opportunity to acquire a larger number of added games than the present, which is advantageous to the player.

  Further, in this embodiment, when any of the replays GR1 to GR6 is won in the added state, it is possible to invalidate the accumulated additional number of games and continue the added state only for the specified number of times (two times). Yes, after that, even if the promotion replay is not won, no additional lottery will be performed, and the number of additional games accumulated in the last period is applied. In other words, the opportunity to acquire the number of additional games more than the current number of times is not obtained any number of times, and the number of times is limited. Therefore, it is possible to add a strategy depending on which player selects.

  In addition, since the “cumulative value of the number of added games at the present time” is displayed on the added zone screen, when any of the replays GR1 to GR6 wins in the added state, the accumulated added number of games is invalidated and further In determining whether or not to continue the added state, it is possible to easily grasp the number of added games accumulated in the added state.

  Furthermore, in the added zone screen displayed on the liquid crystal display 51 in the added state, in addition to the “cumulative value of the number of added games at the present time”, it is possible to invalidate the accumulated added number of games and continue the added state. Number of times ("remaining number of times the continuation of the added state can be selected") is displayed, and the "cumulative value of the number of additional games at the present time" and "the remaining number of times that the continuation of the added state can be selected" It is possible to grasp, and when any of the replays GR1 to GR6 wins in the added state, it is possible to easily determine whether it is a good idea to continue the added state.

  In addition, when any of the replays GR1 to GR6 is elected in the added state, the added zone screen displays the number of invalidated added games when the accumulated added game number is invalidated and the added state is continued. Cumulative values ("previous added games", "previous added games") are displayed and can be compared with the added games accumulated in the subsequent added state, and the number of added games accumulated by the player It is possible to easily grasp whether the judgment of invalidating and continuing the added state is correct or incorrect.

  Further, in this embodiment, after the transition to the added state, the replays GR1 to GR6 that can be shifted from the normal / RT1 to the normal / RT0 arrive at the time of winning, that is, according to the determination result of the internal lottery. Each time it arrives, it is possible to select whether to shift to AT based on the number of added games accumulated in the added state, or to invalidate the accumulated number of added games and continue the added state. Since the period of the additional state accumulated without the invalid number of games being invalidated varies until the selection becomes possible, depending on the replays GR1 to GR6, such a state continues for a long period of time. There is a possibility that the number of added games will be accumulated, and it can be expected that the period will continue for a long time.

  In this embodiment, after the transition to the added state, each time an arrival time is reached according to the result of the internal lottery, that is, the result determined by the main control unit 41, the number of added games accumulated in the added state is based on the number of added games. To make the transition to AT, or to invalidate the accumulated number of added games and continue the added state, and to associate the control content of the main control unit 41 with the player's selection result Although it is preferable that each time a trigger arrives in accordance with the lottery result performed by the sub-control unit 91, it is shifted to the AT based on the number of added games accumulated in the added state, or the accumulated number of added games is set. Even if it is configured to be able to select whether to invalidate and continue the additional state, the number of additional games will be increased until these selections are possible Varying the duration of the plus state to be accumulated does not become effective is possible, in the same manner as described above, it can be expected for that the period continues for a long period of time.

  Further, in this embodiment, after the transition to the added state, the result of the internal lottery, that is, the number of added games accumulated in the added state every time the arrival time corresponding to the lottery result performed for each game is reached. Can be switched to AT, or the number of accumulated additional games can be invalidated and the additional state can be continued, but it can be selected according to the lottery result that is determined for each of a plurality of predetermined games. Each time a trigger is reached, it is possible to select whether to shift to AT based on the number of added games accumulated in the added state, or to invalidate the accumulated number of added games and continue the added state. Even so, it is possible to change the period of the added state that is accumulated without invalidating the number of added games until these selections are possible. Similarly, it can be expected that the period will continue for a long period of time, and in addition, the predetermined number of games is not necessarily invalidated and the added period is accumulated without being invalidated. Since this will continue, it is possible to effectively increase the expectation that a large number of additional games will be accumulated.

  In addition, after the transition to the added state, every time when an opportunity arrives in accordance with the lottery result performed for each game, the transition is made to AT based on the number of added games accumulated in the added state, or this accumulated additional amount is added. Even when the number of games is invalidated and the additional state can be continued, for example, after a plurality of predetermined games have passed, an opportunity to arrive according to a lottery result performed for each game Even when it is configured to be able to select whether to shift to AT based on the number of added games accumulated in the added state or to invalidate the accumulated number of added games and continue the added state In the case of a plurality of predetermined games, the number of additional games is not necessarily invalidated, and the period of the additional state that is accumulated continues. It is possible to increase the expectations for the beam number is accumulated effectively.

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

  In the above embodiment, AT is applied as an advantageous game state, that is, a game state in which an operation mode for deriving a stop mode advantageous to the player is applied. A gaming state that can be expected to win more medals than usual by increasing the probability of winning a prize or notifying the player of information that is advantageous to the player, such as an operation mode for deriving a stop mode that is advantageous to the player. Even if the BB or RB that shifts with the winning of a special role, that is, a gaming state in which the winning probability of a small role is higher than usual, a re-game high probability state in which the winning probability of a re-playing role is increased, etc. good.

  In the above embodiment, the number of AT games, that is, the number of continuous games in the advantageous gaming state, is applied as the advantage of the advantageous gaming state that shifts after the specific gaming state (additional state). The degree is the probability that a winning will be allowed (winning probability of a small role, replaying role, or special role), the probability that an advantageous gaming state will continue for each determined number of games (whether or not to continue AT). The number of games controlled to be in an advantageous gaming state (such as the number of continuing games of the AT), and the number of rights that the advantageous gaming state continues over the determined number of games (for example, the number of games to be controlled by the AT over a predetermined number of games). Right to be controlled, etc.), probability of whether or not information advantageous to the player is notified (an operation mode for avoiding an advantageous game state termination condition, an operation mode for satisfying a transition condition to the advantageous game state, etc.) But As long as the player's advantage changes depending on whether or not these probabilities, the number of games, and the number of rights are favored to the player. .

  Moreover, in the said Example, after shifting to an addition state, whenever it arrives according to the result of internal lottery, ie, the opportunity which comes according to the lottery result performed for every game, it is based on the number of addition games accumulated in the addition state. To change to AT, or to invalidate the accumulated number of added games and continue the added state, that is, the period of the added state in which the number of added games is accumulated without being invalidated varies However, every time a predetermined number of games is reached after shifting to the added state, the game is shifted to AT based on the number of added games accumulated in the added state, or the accumulated number of added games is invalidated. That can be added and continue the added state, that is, the period of the added state that is accumulated without invalidating the number of added games is fixed A configuration may be.

  In the configuration in which the period of the added state accumulated without invalidating the number of added games is fixed, when any of the replays GR1 to GR6 is elected during the fixed period, that is, when it is possible to shift to normal / RT0, It is preferable to notify the operation mode in which the promotion replay that will be shifted to normal / RT0 is not awarded. With such a configuration, the promotion replay is accidentally awarded during the fixed period, and the added state is terminated. Can be prevented.

  Moreover, in the said Example, replay GR1-6 is elected and it selects based on the number of the additional games accumulated in the addition state by selecting the operation mode for winning the promotion replay that will shift to normal / RT0. It is configured to move to AT immediately after selecting to shift to AT, but immediately shifts to AT when the player chooses to shift to AT based on the number of added games accumulated in the added state The configuration is not limited to this, and a configuration in which the player shifts to the AT when a predetermined start condition is satisfied after the player selects to shift to the AT based on the number of added games accumulated in the added state may be used.

  Moreover, in the said Example, replay GR1-6 is elected and it selects based on the number of the additional games accumulated in the addition state by selecting the operation mode for winning the promotion replay that will shift to normal / RT0. By selecting an operation mode that does not shift to AT and selecting an operation mode that does not win the promotion replay, it is selected to invalidate the accumulated number of additional games and continue the additional state, that is, the game progresses It is possible to select whether to shift to AT based on the number of added games accumulated in the added state by using the operation for making it, or to invalidate the accumulated number of added games and continue the added state Are switches that are used only for operations that are disabled for the progress of the game or operations related to performances ( Select whether to shift to AT based on the number of added games accumulated in the added state using the operation of the outgoing switch 56 or the like, or to invalidate the accumulated number of added games and continue the added state A possible configuration is also possible.

  Further, in the above embodiment, an extra lottery is performed based on the result of the internal lottery in the extra state, and the subsequent AT advantage is determined, that is, as an event in the specific gaming state before the transition to the advantageous gaming state. Although the results of the internal lottery are applied, the events that trigger the advantage in a specific gaming state are not limited to the results of the internal lottery, but the occurrence of winnings, the reel stop mode, the presence or absence of freezing, etc. are applied Further, the type of effect selected by the sub control unit 91, the result of the lottery performed by the sub control unit 91, and the like may be applied.

  Further, in the above-described embodiment, as the specific gaming state, after AT winning, the replay GR 1 to 6 are won in normal / RT1 where the payout rate of medals per game is less than 1, and the payout rate of medals per game is 1 Although the period until the transition to normal / RT0 is possible is applied, a gaming state in which the payout rate of medals per game exceeds 1 may be applied as the specific gaming state.

  When a game state in which the payout rate of medals per game exceeds 1 is applied as the specific game state, the advantage is invalidated and the specific game state is continued. It is preferable that the merit payout rate per game is controlled to be less than 1 while the merit payout rate is invalidated and a new merit determination is made. Thus, by extending the specific gaming state, it is possible to prevent the player from gaining an advantage other than obtaining an opportunity to obtain a higher advantage than the present.

In the above embodiment, although the betting amount with medals and credits the present invention as a valuable gaming has been described as being applied to a slot machine to be set, sets the bet number with the game ball as the value for a game slots The present invention may be applied to a machine or a fully credit type slot machine that sets a bet amount using only credit as a gaming value. In the case of using a game ball as a game value, for example, one medal can correspond to five game balls, and when three bets are set in the first embodiment, 15 game balls are used. This is equivalent to setting the number of bets using.

  Further, the present invention is not limited to the use of only one of a plurality of types of game values such as medals and game balls, for example, a combination of a plurality of types of game values such as medals and game balls. It may be. That is, it is possible to play a game by setting the number of bets using any of a plurality of types of gaming values such as medals and game balls, and a plurality of types of games such as medals and game balls when a winning occurs. You may apply the slot machine which can pay out all of utility values.
