Description

  The present invention includes a variable display device capable of deriving and displaying a plurality of types of identification information each identifiable in each of a plurality of variable display areas capable of variably displaying, and is derived and displayed in a plurality of variable display areas. The present invention relates to a slot machine in which a winning can be generated according to a combination of identification information.

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

  In addition, in this type of slot machine, when any winning combination is won in the internal lottery, even if the stop operation is not performed at the timing when the constituent symbol of the winning combination is stopped, If it is within the range, the corresponding symbol is drawn and stopped.

  In this way, as a slot machine that performs control to pull in and stop the symbol, either of the roles is won in the internal lottery, and the symbols constituting the internal winning combination are arranged in the drawing range When the player performs a reel stop operation, the number of sliding symbols of the symbols constituting the internal winning combination is determined based on the internal winning combination from the range of 0 to 4 frames, and the number of sliding frames is determined from 2 frames. In the case of 4 frames, the symbols constituting the internal winning combination are drawn while the reel is stopped at the normal stop speed, while when the number of sliding frames is 1, the number of sliding frames is 2 to 4 By pulling in the symbols that make up the internal winning combination while stopping the reels so that the reel stop speed is slower than when determined in the range up to the top, let the player recognize the number of sliding symbols Suggesting winning by, has been proposed to increase the player's interest (e.g., see Patent Document 1).

Including
The special derivation control means performs the special derivation control (low speed stop control) at least when the occurrence of the special prize (special role) is permitted, and the special decision (special role winning flag) by the carryover means. ) Is carried over, the special winning (special role) is generated by the pre-deciding means (internal lottery) in a state where the special decision (winning flag for special role) is not carried over by the carry-over means. It is characterized in that the special derivation control (low speed stop control) is performed at a higher rate than the game in which it is determined that it is permitted and the special event (winning of simultaneous winning combination) occurs.
According to this feature, the game is determined to allow a special prize to be generated in a state where the special decision has not been carried over, and more than a game in which a special event suggesting that a special prize may be permitted is generated. After the game, the special derivation control is performed at a higher rate in the game where the special decision is carried over by the carry-over means, so the game after the carry-over of the special decision that the player pays attention to due to the occurrence of the special event The special derivation control will be performed at a high rate in the game, so that the player can be effectively recognized that the special derivation control has been performed, so the display result is derived in a special stop mode. The interest can be enhanced effectively, and the player's expectation enhanced by the occurrence of the special event can be sustained by the special derivation control.
Note that special derivation control refers to the behavior at the time of stopping, such as control that makes the speed from when the derivation operation means is operated to when the display result is derived slower than usual, or bounces the display result and stops it. This includes control that makes the behavior different from normal.
Further, the special derivation control means may perform the special derivation control only when the occurrence of the special prize is permitted, without performing the special derivation control when the occurrence of the special prize is not permitted. .

The variable display device is capable of variably displaying a plurality of types of identification information each identifiable, and from a plurality of variable display areas (left reel, middle reel, right reel) from which display results can be derived. Become
The derivation control means is a range of a predetermined maximum fluctuation amount (4 frames) from when the derivation operation means is operated when the derivation operation means (stop switches 8L, 8C, 8R) is operated. Among the display results that can be derived to the variable display area corresponding to the derivation operation means, any display result that can be derived according to the determination result of the prior determination means (internal lottery) corresponds to the derivation operation means. Control to be derived to the variable display area
The winning is derived from a special display result (cherry for the left reel and bell for the middle reel) in the specific variable display area (left reel, middle reel) among the plurality of variable display areas (left reel, middle reel, right reel). Including a special prize (cherry) that occurs regardless of the display result derived in the non-specific variable display area (reel 2R) other than the specific variable display area,
The normal derivation control means derives the display result within the range of the maximum fluctuation amount (4 frames) from the time when the derivation operation means is operated, and the fluctuation amount (slippery) until the display result is derived. Perform normal derivation control (normal stop control) to derive the display result in the normal stop mode that increases the time required to derive the display result in proportion to the increase in the number of frames)
The special derivation control means specifies that the amount of variation (the number of sliding frames) from when the derivation operation means (stop switches 8L, 8C, 8R) is operated until the display result is derived is less than the maximum variation amount. The display result is derived with the specific variation amount (2 frames) in the normal stop mode (normal stop control) as the time until the display result is derived on the condition that the amount of variation is 1 frame. Special derivation control for deriving the display result in a special stop mode that requires a time (114.24 to 147.84 ms, 152.32 to 185.92 ms) exceeding the time required for (70.04 to 108.64 ms) ( Low-speed stop control)
The special derivation control means performs the special derivation control (low speed stop) when it is determined by the predetermining means (internal lottery) that the special winning (cherry A, special role + cherry A) is allowed to occur. Control) and
The derivation control means starts when the derivation operation means corresponding to the non-specific variable display area (right reel) is operated when the occurrence of the special prize (cherry A, special role + cherry A) is allowed. The ratio at which the display result is derived with the specific variation amount (two frames) in the non-specific variable display area (right reel) (the ratio at which two frames are selected with respect to 21 stop operation positions) is the specific variable display. From the rate at which the display result is derived with the specific variation (two frames) in the specific variable display area (left reel, middle reel) from the time when the derivation operation means corresponding to the area (left reel, middle reel) is operated. It is also characterized by high price.
According to this feature, special derivation control is performed when occurrence of a special prize is permitted and the amount of specific variation is present, and when the occurrence of a special prize is permitted, a non-specific variable display area, that is, a special prize is displayed. In the variable display area where the display result does not affect the occurrence, the ratio for deriving the display result with the specific variation amount than the specific variable display region, that is, the variable display region in which the variation amount is limited in order to derive the special display result. Since the opportunity for deriving the display result in a special stop mode can be increased by increasing the value, the interest by deriving the display result in the special stop mode can be effectively enhanced.
The special derivation control is a special stop mode that requires a time exceeding the time required for deriving the display result with the specific variation amount in the normal stop mode as the time until the display result is derived. For example, control for deriving the display result after the operation of the derivation operation means until the display result is derived, This includes control that causes the behavior when stopping to be different from normal, such as stopping by bouncing.

The slot machine according to means 6 of the present invention is the slot machine according to means 5,
The special derivation control means performs control for deriving a display result in the special derivation control (low speed stop control) for any one of the variable display areas (left reel, middle reel, right reel). In this case, the control for deriving the display result is not performed in the special derivation control (low speed stop control) for the other variable display areas.
According to this feature, the display result is derived in a special stop mode only in one variable display area, and the display result is derived in the normal stop mode in the other variable display area. You can highlight what has been done.

The slot machine of means 7 of the present invention is the slot machine according to means 5 or 6,
In the special winning (cherry), the first special display result (cherry) is derived to the first specific variable display area (left reel) of the specific variable display areas, and the second specific variable display area (middle) Only the second special display result (bell) is derived to the reel) and occurs regardless of the display result derived to the non-specific variable display area (right reel),
The derivation control means includes
When it is determined that the occurrence of the special prize (cherry) is permitted, the derivation operation means corresponding to the first specific variable display area (left reel) is operated at a specific timing (cherry pull-in range). Only when the first special display result (cherry) is derived, the second specific variable is always performed regardless of the operation timing of the deriving operation means corresponding to the second specific variable display area (medium reel). While performing control to derive the second special display result (bell) to the display area (middle reel),
When the special winning (cherry) is allowed to occur, the specific variable display area (right reel) is specified from the point when the derivation operation means corresponding to the non-specific variable display area (right reel) is operated. The ratio at which the display result is derived with the amount of variation (2 frames) is the first specific variable display area (left) from the time when the derivation operation means corresponding to the first specific variable display area (left reel) is operated. It is characterized in that it is higher than the rate at which the display result is derived with the specific fluctuation amount (2 frames) on the reel).
According to this feature, the first specific variable display area, that is, the first specific variable display area, ie, the first specific variable display area, that is, the first specific variable display area, that is, the variable display area that does not affect the occurrence of the special prize when the special winning is allowed. In order to derive one special display result, the specific variation amount is larger than the variable display region in which the display result needs to be derived with a variation amount other than the specific variation amount among the maximum variation amounts at the timing when the derivation operation means is operated. By increasing the ratio of deriving the display result, it is possible to reliably increase the opportunity for deriving the display result in a special stop mode.

The slot machine of means 8 of the present invention is the slot machine according to any one of means 1 to 7,
The variable display device changes a display state by rotating display bands (reels) corresponding to the plurality of variable display areas (reels 2L, 2C, 2R) by a stepping motor (reel motors 32L, 32C, 32R). In addition, the display result is derived and displayed by stopping the rotation of the display band (reel).
Constant speed control means for performing constant speed rotation control for rotating the display band (reel) at a constant speed by changing an excitation pattern for a plurality of excitation phases (φ1 to φ4) of a stepping motor (reel motors 32L, 32C, 32R). With
The derivation control means includes
After performing deceleration control to decelerate the rotation speed of the display band (reels 2L, 2C, 2R), the display band (reel) is performed by performing all-phase excitation for exciting all of the plurality of excitation phases (φ1 to φ4). 2L, 2C, 2R) and stop control,
A first stop control (normal stop control) for starting the deceleration control from a first deceleration start position before the stop position with respect to the rotation direction (position 6 steps before the stop position); and the rotation direction In contrast, a second stop control (low speed stop) for starting the deceleration control from a second deceleration start position (position 38 steps before the stop position) that is farther from the stop position than the first deceleration start position. Control 1), and
The special derivation control means performs the second stop control (low speed stop control 1) as the special derivation control,
The derivation control means, when performing the second stop control (low speed stop control 1), a first all-phase start position for starting the all-phase excitation in the first stop control (normal stop control). The all-phase excitation is started at a second all-phase start position (position two steps before the stop position) closer to the stop position than (a position five steps before the stop position).
According to this feature, even when stopping at the same position, when the second stop control is performed, the display is made after the deceleration is started as compared with the case where the first stop control is applied. The time required for the belt to stop becomes longer, and the mode from the start of deceleration to the stop can be diversified. When the second stop control is performed, all-phase excitation is performed in the first stop control. Since the all-phase excitation is started at the second all-phase start position that is closer to the stop position than the first all-phase start position to be started, the deceleration control is started earlier than the first stop control. Even when the second stop control in which the inertial force is weakened, the stop can be stopped at the same stop position as the first stop control.
The deceleration control may be a control for decelerating the rotation speed of the display band by extending the control time to one excitation pattern than at the constant speed rotation, or the excitation pattern at the constant speed rotation. The rotation speed of the display band is reduced by changing the excitation pattern in a different order from the order of change, or by exciting with a pattern in which the excitation phase is excited with a pattern different from the excitation pattern performed at constant speed rotation. It is also possible to perform control.
The deceleration start position at which deceleration control is started is the timing at which control different from the excitation control at the time of constant speed rotation is actually started, and waiting for the start of deceleration with the same control as at constant speed rotation. State does not apply.

The slot machine according to means 9 of the present invention is the slot machine according to means 8,
In the case where the second stop control is performed, the derivation control unit performs the above-described operation until the predetermined deceleration start position (position 38 steps before the stop position) is reached after the derivation operation unit is operated. It is characterized by continuing constant speed rotation control (control at the same step rate as constant speed rotation).
According to this feature, it is possible to perform the second stop control by common control even when the operation timing of the derivation operation means is different, and it is possible to prevent the control from becoming more complicated than necessary.

The slot machine of means 10 of the present invention is the slot machine according to means 8 or 9, wherein
The variable display device is composed of a plurality of display bands (reels 2L, 2C, 2R),
The derivation control means performs the second stop control only when stopping the display band (final stop reel) that stops last among the plurality of display bands.
According to this feature, control other than the display band that stops last is always controlled by the first stop control, and only the display band that stops last is controlled by the second stop control. Therefore, there is no variation in the time from when the player operates the derivation operation means until the remaining display band operation becomes effective, and the derivation operation means is at a timing not intended by the player. Can be prevented from being performed.

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.

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 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.

  The important work is a work in which data such as various display devices and LED display data, I / O input / output data, game time counter, etc., which are inconvenient to be initialized are stored. 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, the slot machine 1 of the present embodiment has a predetermined number of bets that can be set according to the gaming state (normal gaming state, RT1 to 4, RB1, RB2, RB3). The game can be started on the condition that a prescribed number of bets determined in accordance with the number of bets is set. In this embodiment, all of the pay lines 1 to 5 are activated when a specified number of bets corresponding to the gaming state are set.

  In the slot machine 1 of this embodiment, when all the reels 2L, 2C, 2R are stopped, 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 the winning flags for each of these combinations, the winning flag for the small role and the re-playing role is valid only in the game in which the flag is set, and is invalid in the next game. It is valid until the combination of combinations permitted by the flag is complete, and is invalid in a game having the combination of combinations permitted. In other words, once the winning flag for a special role is won, even if the combination of characters allowed by the flag cannot be aligned, the winning flag is not invalidated and is carried over to the next game. It becomes.

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

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

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

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

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

  In this embodiment, as a reel stop control method, stop control (hereinafter also referred to as a table method) based on sliding frame number data (data indicating the number of sliding frames corresponding to the stop operation position) registered in the ROM 506 in advance is used. Two methods of stop control based on the search result (hereinafter also referred to as control method) are adopted at each operation timing, and either one is selected depending on the result of the internal lottery and the reel stop status. Stop control is performed by the method described above.

  In this embodiment, the sliding frame number data and the internal lottery result corresponding to the first stop corresponding to all the internal lottery results and the internal lottery result corresponding to the first stop (stop operation first performed while all reels are still rotating). This is the result (BB1 to 4 in this embodiment), the first stop reel is the left reel, and the stop position is a specific stop position determined according to the specific result (in this embodiment, the lower 17 2nd stop (any one reel) corresponding to the case of the stop position of the lower stage, the stop position of the lower stage 11, the stop position of the lower stage 7, the stop position of the lower stage 2, the stop position of the lower stage 0 Is already stopped, two reels are rotating, ie, the second stop operation), and third stop (any two reels are stopped and one reel is rotating, ie, third) Number of sliding frames corresponding to the stop operation to be performed) Data is pre-registered in the ROM 506, and at the time of the first stop, regardless of the result of the internal lottery, the stop control is performed by the table method using the corresponding sliding frame number data, and at the time of the second stop and the third stop, If the internal lottery result is a specific lottery result and the specific stop position is stopped on the first stop reel, stop control is performed by the table method using the corresponding sliding frame number data, and the internal lottery result is specified. If it is not the result of the lottery, or if the specific stop position is not stopped on the first stop reel, stop control is performed by the control method.

  The sliding frame number data used when the stop control is performed by the table method is registered in advance in the ROM 506 and is selected with reference to the table index stored in the ROM 506.

  The sliding frame number data 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 335 steps, the reels 2L, 2C, and 2R make one round. As shown in FIG. 38, 21 areas (frames) divided every 16 steps (the number of steps in which one symbol moves) are defined with respect to one reel. Area numbers 0 to 20 are assigned from the position. 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 sliding frame number data, the sliding frame number by area number is compressed and stored according to a predetermined rule, and the sliding frame number by area number can be acquired by expanding the sliding frame number data. It has become.

  Here, the content of stop control according to the stop control method will be described.

  First, when the main control unit 41 performs stop control by the table method, as shown in FIG. 36, when the rotation of the reel starts or the reel stops, the reel that is still rotating still remains. Sometimes, if there is a reel that has been stopped as a result of the internal lottery with respect to an unstopped reel, the stop corresponding to the stop position of the reel is stopped by referring to the table index before the reel stop operation becomes effective. Select the sliding frame number data in the control table.

  Then, the selected sliding frame number data is expanded and stored in a virtual sliding frame table (see FIG. 38) assigned to the RAM 507.

  As shown in FIG. 38, in the virtual sliding top table, for each reel, the area corresponding to each area number corresponds to the stop reference position (in this embodiment, the lower symbol area in the perspective window 3). ) (The number of steps from the reel reference position is included in the range of the number of steps of each area number), and the number of sliding frames when the operation of the stop switches 8L, 8C, 8R is detected is stored. The number of sliding symbols developed from the sliding frame number data is stored in correspondence with the corresponding area number of the corresponding reel.

  Thereafter, the stop operation is validated. In this state, when any of the stop switches 8L, 8C, 8R corresponding to the rotating reel is effectively detected, the reel reference at the time when the stop operation is detected. The area number of the stop operation position is identified based on the number of steps from the position, and the number of sliding frames corresponding to the identified area number of the stop operation position is obtained by referring to the virtual sliding frame table of the reel where the stop operation is detected. To do. Based on the acquired number of sliding symbols, control is performed to stop the rotation of the reels 2L, 2C, 2R corresponding to the operated stop switches 8L, 8C, 8R.

  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 until the stop is calculated, and the reel is rotated and stopped by the calculated number of steps. Do. As a result, an area (stop point in the figure) corresponding to the area number that is the stop position ahead of the number of sliding frames from the area (stop operation point in the figure) corresponding to the area number of the stop operation position in which the stop operation is detected. It stops at the stop reference position (in this embodiment, the lower symbol area of the fluoroscopic window 3).

  Next, when the main control unit 41 performs stop control by the control method, as shown in FIG. 37, when the reel is stopped and the reel that is still rotating still remains, the reel stop operation is performed. The stop position corresponding to the result of the internal lottery for each stop operation position based on the stop position of the reel that has been stopped as a result of the internal lottery for the reels that have not been stopped before the stage is activated (the winning combination is placed on the winning line) Search for the same stop position).

  Specifically, for each stop operation position, a stop position for each of the 0 to 4 sliding frames is specified, and each of these stop positions is determined for illegal winning (a role not won in the internal lottery) and a stop prohibited position ( In the case of a stop, a determination is made of a stop position where it is not possible to avoid illegal winnings or duplicate winnings on an unstopped reel. If it is an illegal winning or stop prohibiting position, a stop prohibiting position flag is set.

  Then, it is determined whether the stop position according to the number of sliding frames from 0 to 4 is the stop position where the winning combination is aligned on the winning line or not. (In this embodiment, the order of 1 → 0 → 2 → 3 → 4 is applied), and when it is determined that the winning combination is a stop position on the winning line, It is determined whether or not the stop prohibition position flag is set for the stop position. If the stop prohibition position flag is not set, the stop position is acquired, and the number of sliding symbols that become the acquired stop position is obtained. Stored in the area number of the corresponding stop operation position of the corresponding reel in the virtual sliding top table.

  Even if it is determined that the winning combination is a stop position on the winning line, if the stop prohibition position flag is set for the stop position, the next stop position is determined. In addition, if there is no stop position where the winning combination is on the winning line even after determining the stop positions of all the slide frames, the number of slide frames that will be the last determined stop position is indicated in the virtual slide frame table. And the area number of the corresponding stop operation position. In addition, when the stop prohibition position flag is set for the stop position determined last, the number of slip frames that is acquired retroactively to the stop position for which the stop prohibition position flag is not set and becomes the acquired stop position Is stored in the area number of the corresponding stop operation position of the corresponding reel in the virtual sliding top table. In this embodiment, as will be described later, the symbols “bell” and “replay” are arranged at intervals of 4 frames or less on all reels, and the reels are pulled in and stopped within the range of 0 to 4 frames. By this, it becomes possible to arrange the bells or replays on the winning line.

  After the number of sliding symbols is stored for all the area numbers of the rotating reels in the virtual sliding frame table, the stop operation is validated, and in this state, among the stop switches 8L, 8C, 8R, the rotating reels When any of the corresponding operations is detected effectively, the area number of the stop operation position is identified based on the number of steps from the reel reference position at the time when the stop operation is detected, and the reel of which the stop operation is detected With reference to the virtual sliding top table, the number of sliding tops corresponding to the area number of the specified stop operation position is acquired. Based on the acquired number of sliding symbols, control is performed to stop the rotation of the reels 2L, 2C, 2R corresponding to the operated stop switches 8L, 8C, 8R.

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

  In the table index, the number of sliding frames that draws the winning combination as much as possible within the range of 4 frames to the address corresponding to the case where one of the roles is won, and draws the winning combination so that there are no winning combinations. In addition to storing index data that specifies the number of sliding frames for which the number is determined, even when performing a stop operation with the control method, the winning combination is drawn to the maximum in the range of 4 frames, The number of sliding frames to be drawn so as not to be aligned is stored in the virtual sliding frame table.

  Therefore, if any winning combination is won, regardless of the stop control method, the maximum number of winning combinations will be drawn within the range of 4 frames, and the number of sliding frames that will be pulled in so that there is no winning combination. Is stored in the virtual sliding top table and the reel stop control is performed. On the other hand, if none of the roles is won, the number of sliding tops that do not have any of the roles is stored in the virtual sliding top table and the reel The stop control is performed. As a result, when the stop operation is performed, if the symbols of the winning combination can be stopped on the winning line in the drawing range of up to 4 frames, the control is performed to align them and stop. The symbol of the winning combination will be controlled to be stopped in a drawing range of a maximum of 4 frames.

  As shown in FIG. 3, “bell”, “replay” on all reels, and “cherry” on the middle reel are arranged at intervals of 4 frames or less, so that “replay” or “bell” is a constituent symbol. When winning a prize, the “replay” or “bell” can always be stopped on the winning line regardless of the timing at which each reel is stopped.

  On the other hand, “Red 7”, “Blue 7”, “Purple 7”, “Watermelon” in all reels, “Zhu 7” and “Cherry” in left and right reels are arranged at intervals exceeding 4 frames. Therefore, when winning a prize with “Red 7”, “Blue 7”, “Purple 7”, “Watermelon” in any reel, “Red 7”, “Cherry” on the left and right reels At the time of winning a prize with the symbol of “Red 7”, “Blue 7”, “Purple 7”, “Watermelon”, “Zhu 7”, “Cherry” in the corresponding reel If the reels are stopped, “Red 7”, “Blue 7”, “Purple 7”, “Watermelon”, “Zhu 7”, “Cherry” can be stopped on the winning line. 7 ”,“ Blue 7 ”,“ Purple 7 ”,“ Watermelon ”,“ Red 7 ”,“ Cherry ” If the corresponding reel is stopped at the timing of “Red 7”, “Blue 7”, “Purple 7”, “Watermelon”, “Zhu 7”, “Cherry” cannot be stopped on the winning line. I will miss it.

  In addition, since “watermelon” is arranged at intervals of 6 frames or less on the left reel, if the winning line is limited as a result of stopping the middle reel or the right reel before the left reel, If the corresponding reel is stopped at a timing outside the "watermelon" pull-in range, the "watermelon" cannot be stopped at the winning line and will be missed. Can be stopped on the winning line regardless of whether it stops at the top or the bottom in the range of 5 frames, so the left reel is the first reel when winning a prize with “watermelon” as the constituent symbol on the left reel. In the case of stopping, the “watermelon” can always be stopped on the winning line regardless of the timing of the stop operation of the left reel.

  If the special role is elected while the special role has been carried over from before the previous game, or if the special role and the small role are elected at the same time when the special role is not carried over, the special role and the small role are won simultaneously. When the 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 to stop them together. If you cannot draw a small role that has been won in the drawing range of up to 4 frames on the winning line, you must stop the special role that has been won in the drawing range of up to 4 frames on the winning line. If it is possible, control is performed to stop all of them together, and a winning combination that has not been won will be controlled to be stopped within the 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 made effective only when the small combination cannot be drawn.

  In this embodiment, when a special role and a small role are simultaneously elected, the control for aligning the small role on the winning line is prioritized over the special role, and the special role is given only when the small role cannot be drawn. However, priority is given to the control of aligning the special role on the winning line over the small role, and it is possible to win the small role only when the special role cannot be drawn. It is good also as a structure.

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

  In this embodiment, after the rotation of the reels 2L, 2C, and 2R is started, the main 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 low speed stop command, a reel rotation start command, a reel stop command, a winning determination command, a payout start command, a payout to the sub control unit 91. A plurality of types of commands including an end command, a gaming state command, a standby command, a stop command, an error command, a return command, a setting command, a setting confirmation command, and an operation detection command are transmitted.

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

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

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

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

  The low speed stop command is a command that can specify the result of the low speed stop lottery described later, that is, whether or not the low speed stop control described later is executed, and is transmitted after the low speed stop lottery.

  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 indicates whether the reel to be stopped is the left reel, the middle reel, or the right reel, the area number of the stop operation position of the corresponding reel, the area number of the stop position of the corresponding reel, normal stop control described later Or low-speed stop control, and is transmitted every time stop control associated with a stop operation of each reel is performed. Since the reel stop command is transmitted when the stop switches 8L, 8C, and 8R are operated, it is possible to specify that the stop switches 8L, 8C, and 8R are operated by receiving the reel stop command. .

  The winning determination command is a command that can specify the presence / absence of winning, the type of winning, the winning line with the winning combination, and the number of medals to be paid out at the winning, and is sent after all reels are stopped and the winning determination is made. The

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

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

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

  Commands other than the operation detection command are generated in the basic process, and are transmitted to the transmission data register 561 of the serial communication circuit 511 to be transmitted to the sub-control unit 91.

  The operation detection command is generated every time the timer interrupt process (main) is executed five times, and is transmitted to the transmission data register 561 of the serial communication circuit 511 to be transmitted to the sub-control unit 91.

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

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

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

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

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

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

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

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

  6 and 7 are diagrams for explaining the types of winning combinations, symbol combinations of winning combinations, and technical matters related to winning combinations. FIG. 8 is a diagram for explaining the transition of the gaming state controlled by the main control unit 41, and FIG. 9 is a diagram showing an outline of the gaming state.

  As shown in FIG. 8, the slot machine in this embodiment is controlled to one of the normal gaming state, the normal gaming state, RT1 to 4, and BB1 to 6, and is always controlled to RB1 in BB1 and BB3. 4 is always controlled to RB2, and BB5 and 6 are always controlled to RB3.

  Referring to FIG. 6, the special combination among the winning combinations includes six types of BBs of big bonuses 1 to 6 (hereinafter, each big bonus is referred to as BB).

  BB1 is awarded when the combination of “red 7-red 7-red 7” is aligned on the winning line. BB2 is awarded when the combination of “blue 7-blue 7-blue 7” is aligned on the winning line. BB3 is awarded when the combination of “Red 7-Red 7-Red 7” is aligned on the winning line. BB4 is awarded when the combination of “purple 7-blue 7-blue 7” is aligned on the winning line. BB5 is awarded when the combination of “red 7-red 7-blue 7” is aligned on the winning line. BB6 is awarded when the combination of “blue 7-blue 7-red 7” is aligned on the winning line.

  When BB1 wins, the game shifts to big bonus 1 (hereinafter referred to as BB1). When BB2 wins, the game shifts to big bonus 2 (hereinafter referred to as BB2). In BB1 and BB2, the regular bonus 1 (hereinafter referred to as RB1) is always controlled until the end condition is satisfied. RB1 is a gaming state in which 1 is defined as the prescribed number of bets, and ends when either of the 12 games is exhausted or four winnings are satisfied, and BB1 or BB2 ends. If not, it will be controlled again by RB1. BB1 and BB2 are terminated on condition that more than 465 medals have been paid out during BB1 or BB2. At this time, even if the termination condition for RB1 is not satisfied, RB1 is also terminated.

  When BB3 wins, the game shifts to big bonus 3 (hereinafter referred to as BB3). When BB4 wins, the game shifts to big bonus 4 (hereinafter referred to as BB4). In BB3 and BB4, the regular bonus 2 (hereinafter referred to as RB2) is always controlled until the end condition is satisfied. RB2 is a gaming state in which 2 is defined as the prescribed number of bets, and ends when either of the 12 games is exhausted or the prize is won four times, and BB3 or BB4 ends. If not, it will be controlled by RB2 again. BB3 and BB4 end on condition that more than 344 medals have been paid out during BB3 or BB4. At this time, even if the termination condition for RB2 is not satisfied, RB2 is also terminated.

  When BB5 wins, the game shifts to big bonus 5 (hereinafter referred to as BB5). When BB6 wins, the game shifts to big bonus 6 (hereinafter referred to as BB6). In BB5 and BB6, the regular bonus 3 (hereinafter referred to as RB3) is always controlled until the end condition is satisfied. RB3 is a gaming state in which 3 is defined as the prescribed number of bets, and ends when either of the 12 games is consumed or the winning of 4 times is satisfied, and BB5 or BB6 ends. If not, it will be controlled by RB3 again. BB3 and BB4 end on condition that more than 105 medals have been paid out during BB3 or BB4. At this time, even if the termination condition for RB3 is not satisfied, RB3 is also terminated.

  As shown in FIG. 8, RT4 is controlled from winning one of BB1 to BB until winning a prize. Moreover, as shown in FIG. 8, after BB1-4 are complete | finished, it controls to a normal game state, and after BB5, 6 is complete | finished, it is controlled to RT3.

  Even if one of the BBs 1 to 6 is won in the internal lottery, if the stop switch 8L, 8C, 8R is not operated at an appropriate timing to make it possible to win these roles, it is possible to win these roles. Absent. This is because the symbols BB1 to BB6 are not arranged at intervals of 4 frames or less on all reels.

  Next, with reference to FIG. 7, the re-game player among the winning combinations will be described. Among the winning combinations, the replay combination includes replay 1, replay 2, and replay 3.

  Replay 1 is awarded when any combination of “Replay-Replay-Replay” and “Bell-BAR-Replay” is aligned on the winning line. “Replay” is arranged at intervals of 4 frames or less on each of the left reel 2L, the middle reel 2C, and the right reel 2R. Therefore, in principle, the replay 1 can be said to be a role that can be awarded regardless of the operation timing of the stop switches 8L to 8R if it is won.

  Replay 2 is awarded when a combination of “Replay-Replay-Bell”, “Bell-Bell-Replay”, “Watermelon-Watermelon-Replay”, and “Watermelon-Replay-Watermelon” is aligned on the winning line. “Replay” and “Bell” are arranged at intervals of 4 frames or less on each of the left reel 2L, the middle reel 2C, and the right reel 2R. Therefore, in principle, the replay 2 can be said to be a role that can be awarded regardless of the operation timing of the stop switches 8L to 8R if it is won.

  As shown in FIG. 8, after winning the replay 2 in the normal gaming state or RT3, it is controlled to RT1.

  Replay 3 is awarded when a combination of “cherry-replay-replay”, “BAR-replay-replay”, “purple 7-replay-replay”, and “watermelon-replay-watermelon” is aligned on the winning line. “Cherry”, “BAR”, and “Purple 7” are arranged at intervals of 4 frames or less on the left reel, and “Replay” is arranged at intervals of 4 frames or less on each of the middle reel 2C and the right reel 2R. ing. Therefore, as a general rule, the replay 3 can be said to be a role that can be awarded regardless of the operation timing of the stop switches 8L to 8R if it is won.

  As shown in FIG. 8, after winning the replay 3 in the normal gaming state or in RT3, it is controlled to RT2.

  Next, with reference to FIG. 7, the small combination among the winning combinations will be described. Among the winning combinations, the small combination includes cherry, bell, watermelon, one-piece combination 1, and one-piece combination 2.

  Cherry has the winning line “ANY-ANY-Cherry” (“ANY” is “Red 7”, “Red 7”, “Blue 7” “Purple 7”, “BAR”, “Watermelon”, “Cherry”, “ When any combination of “Replay”, “Bell”, and “Plum”) is completed, if the gaming state is the normal gaming state, RT1-4, one medal is paid out and the gaming state is If RB1 to RB3, 15 medals are paid out. Note that when “Cherry” stops at the upper or lower stage of the right reel, the two winning lines are aligned, so that two medals are paid out in the normal gaming state, RT1 to RT4. In RB1 to RB3, the maximum payout number will be exceeded even if the two pay lines are aligned, so the payout will be 15.

  Here, referring to FIG. 3, “cherries” are arranged at intervals exceeding 6 frames that can be stopped at either the upper stage or the lower stage in the right reel 2 </ b> R. For this reason, if the cherry is won in the internal lottery, the winning cherry will not be won unless the stop switch 8R corresponding to the right reel is operated at an appropriate timing.

  Bell wins when the combination of “Bell-Bell-Bell” is aligned on the winning line. If the gaming state is the normal gaming state, RT1-4, eight medals are paid out and the gaming state is RB1. If it is ~ 3, 15 medals will be paid out.

  Here, referring to FIG. 3, the bells are arranged at intervals of 4 frames or less on each of the left reel 2L, the middle reel 2C, and the right reel 2R. For this reason, it can be said that, in principle, when a bell is won in the internal lottery, a prize can be awarded regardless of the operation timing of the stop switches 8L to 8R.

  Watermelon is awarded when the combination of “Watermelon-Watermelon-Watermelon” and “Watermelon-Watermelon-BAR” is complete on the winning line. If the gaming state is the normal gaming state, RT1-4, 10 medals will be awarded. If it is paid out and the gaming state is RB1 to 3, 15 medals are paid out.

  Here, referring to FIG. 3, “watermelons” are arranged at intervals exceeding four frames in the left reel 2L, the middle reel 2C, and the right reel 2R. For this reason, when the watermelon is won in the internal lottery, if the stop switches 8L, 8C and 8R are not operated at an appropriate timing, the winning watermelon will not be won. In the left reel 2L, the “watermelons” are arranged at intervals of 6 frames or less that can be stopped at either the stage or the lower stage. Regardless of the operation timing of the switch 8L, the "watermelon" can be stopped on the winning line on the left reel.

  The single winning combination 1 is awarded when the combination of “blue 7-BAR-blue 7” is arranged on the winning line, and if the gaming state is the normal gaming state, RT1 to 4, one medal is paid out. If the gaming state is RB1 to 3, 14 medals are paid out.

  Here, referring to FIG. 3, “blue 7” is arranged with an interval exceeding 4 frames in the left reel 2L and the right reel 2R, and “BAR” is an interval exceeding 4 frames in the middle reel 2C. Are arranged. Therefore, when the winning combination 1 is won in the internal lottery, if the stop switches 8L, 8C, and 8R are not operated at an appropriate timing, the winning winning combination 1 will not be won.

  One-piece combination 2 wins when the combination of “cherry-blue 7-red 7” is aligned on the winning line, and if the gaming state is the normal gaming state, RT1-4, one medal is paid out. If the gaming state is RB1 to 3, 15 medals are paid out.

  Here, referring to FIG. 3, “cherry” is arranged at intervals exceeding 4 frames in the left reel 2L, and “blue 7” is arranged at intervals exceeding 4 frames in the middle reel 2C. “Red 7” is arranged at intervals exceeding 4 frames in the right reel 2R. For this reason, when the single winning combination 2 is won in the internal lottery, the winning single winning combination 2 is not won unless the stop switches 8L, 8C and 8R are operated at an appropriate timing.

  Next, with reference to FIGS. 10 to 13, combinations of lottery object combinations that are read as lottery object combinations for each gaming state will be described. In this embodiment, an internal lottery is selected depending on whether the gaming state is a normal gaming state, RT1, RT2, RT3, RT4, or RB1 to RB3. The roles and their winning probabilities are different. 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. 10 to 13, “+” is written between winning winning combinations to indicate that the winning combination is simultaneously read in the internal lottery.

  In FIGS. 10 to 13, the lottery object 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.

  10 to 12 show combinations of special combinations that are read out as lottery targets for each gaming state, and FIG. 13 shows combinations of re-game and small combinations that are read out as lottery targets for each gaming state. ing. FIG. 14 shows combinations of the combinations that make up the winning combinations shown in FIGS.

  When it is RT4, watermelon A, watermelon B, cherry A, cherry B, bell, replay A, replay B1, replay B2, and replay C are targeted for internal lottery.

  When RB1 to RB3, watermelon B, cherry B, and bell are subject to internal lottery.

  As shown in FIG. 14, the watermelon A is a watermelon alone, and the watermelon B is a watermelon + 1 combination 1. When winning a watermelon A or a watermelon B, a stop operation is performed at the timing of the “watermelon” or “BAR” pull-in range of the left reel, the middle reel “watermelon”, and the right reel “watermelon”. -"Watermelon" or "Watermelon-Watermelon-BAR" combination is controlled so that it can be derived to the winning line, but when Watermelon A is selected, the control of pulling the "Watermelon-Watermelon-Watermelon" combination to the winning line is performed as much as possible. Only when the “watermelon-watermelon-watermelon” combination cannot be withdrawn and the “watermelon-watermelon-BAR” combination can be withdrawn, the control of drawing the “watermelon-watermelon-BAR” combination into the winning line is performed. When watermelon B is selected, control is performed to pull the “watermelon-watermelon-BAR” combination to the winning line as much as possible. Not retract the combination of -BAR "," watermelon - if retract the combination of watermelon -BAR "only," watermelon - Control pulling the winning line a combination of watermelon -BAR "is performed. That is, when winning the watermelon A, the “watermelon-watermelon-watermelon” combination is easy to align with the winning line, and when winning the watermelon B, the “watermelon-watermelon-BAR” combination is easy to align with the winning line. It is possible to recognize whether the watermelon A or the watermelon B has been won depending on whether the combination of “watermelon-watermelon” or “watermelon-watermelon-BAR” is complete.

  Cherry A is a cherry alone, and Cherry B is a cherry + 1 sheet 2 combination. When winning Cherry A and winning Cherry B, both the “ANY-ANY-Cherry” combination is controlled so that it can be derived to the winning line by stopping at the timing of the “Cherry” pull-in range of the right reel. However, when Cherry A is selected, “Cherry” is drawn on the same winning line until the second stop for any reel (if the right reel is set to the third stop, the other reels at the third stop) On the other hand, the “Cherry” is selected as the winning line except for the winning line where “Cherry” is tempered (the winning line where “Cherry” is arranged except for the third stop reel). At that time, all reels are controlled to draw the “cherry-cherry-cherry” combination to the winning line as much as possible. When Lee A is selected, it is difficult to stop “Cherry” on the winning line of “Cherry” who has been tempered until the second stop, and when Cherry B is selected, the “Cherry” is tempered until the second stop. Since “Cherry” is likely to stop on the winning line, whether Cherry A has been won or Cherry B depends on whether or not “Cherry” has stopped on the winning line of “Cherry” that has been tempered by the second stop. It becomes possible to recognize whether or not is won.

  The replay A is the replay 1 alone, and when the replay A is won, control for drawing the “replay-replay-replay” combination into the winning line is performed regardless of the timing of the stop operation.

  Replay B1 is Replay 2 + Replay 1 and Replay B2 is Replay 2 alone. When Replay B1 is selected, the combination of “Replay-Replay-Bell” is drawn into the winning line regardless of the timing of the stop operation. On the other hand, when replay B2 is selected, control is performed to draw in the combination of “watermelon-watermelon-replay” or “watermelon-replay-watermelon” as much as possible, and the combination of “watermelon-watermelon-replay” is also “watermelon” If the combination of “Replay-Watermelon” cannot be pulled in, control is performed to pull in the combination of “Replay-Replay-Bell” or “Bell-Bell-Replay”. That is, when Replay B1 is selected, the combination of “Replay-Replay-Bell” is always on the winning line, and when Replay B2 is selected, the combination of “Watermelon-Watermelon-Replay” or “Watermelon-Replay-Watermelon” is easily aligned. Whether Replay B1 or Replay B2 is won, depending on whether "Replay-Replay-Bell" combination, "Watermelon-Watermelon-Replay" or "Watermelon-Replay-Watermelon" combination is complete , Can be recognized.

  Replay C is Replay 2 + Replay 3, and when Replay C is won, regardless of the timing of the stop operation, "Cherry-Replay-Replay", "BAR-Replay-Replay" or "Purple 7-Replay-Replay" Control to draw one of the combinations into the winning line is performed.

  Further, although not particularly illustrated, control is performed so that “cherry” can be stopped on the winning line of the left reel when any special combination is won and any general combination is not selected. On the other hand, except for the case where cherry A or cherry B is won, control is performed so that “cherry” does not stop on the winning line of the left reel. Therefore, when “Cherry” stops on the winning line of the left reel, and “Cherry” does not stop on the winning line even though the “Cherry” pull-in range of the right reel is stopped. , The reach (a stop mode that appears on the condition that the special role is won) will be established.

  15 to 25 show the number of determination values according to settings 1 to 6 used for the internal lottery. Of these, FIGS. 15 to 17 show the number of judgment values of the special combination and special combination + general combination used in the normal gaming state and RT1 to RT3. FIG. 18 shows the number of judgment values for the small combination and re-playing combination used in the normal gaming state. FIG. 19 shows the number of determination values of re-game players used in RT1. FIG. 20 shows the number of determination values of the re-gamer used in RT2. FIG. 21 shows the number of determination values of re-game players used in RT3. Note that the number of small combination determination values used in RT1 to RT3 is the same as the number of small combination determination values used in the normal gaming state, and is therefore omitted in FIGS. FIG. 22 shows the number of judgment values for the small combination and re-playing combination used in RT4. FIG. 23 shows the number of small combination determination values used in RB1. FIG. 24 shows the number of small combination determination values used in RB2. FIG. 25 shows the number of small combination determination values used in RB3. Also, in FIG. 18 to FIG. 25, the value corresponding to (losing) is a value obtained by subtracting the total number of determination values of the lottery target role as a target in the corresponding gaming state from the total number of random numbers for internal lottery “65536”. Yes, the number of determination values corresponding to the loss is not stored in the ROM 506.

  The denominator of the number of determination values is set to “65536” in correspondence with a random number for internal lottery (an integer from 0 to 65535). For this reason, for example, when the normal gaming state and the setting value are setting 1, the number of determination values of BB1 is 2, and the winning probability of BB1 in the normal gaming state and setting 1 is 2/65536. In addition, although it is not the number of determination values, for example, the value corresponding to the loss in the normal gaming state and the set value is 1, and therefore, the probability of the loss in the normal gaming state and the setting 1 is 45390/65536. It becomes.

  FIG. 26 shows the simultaneous winning expectation degree for each set value at the time of a general winning combination that is a lottery target in the normal gaming state. The simultaneous winning expectation is the ratio that the special role is won at the same time when the target general role is won, that is, the degree of the possibility that the special role is won at the same time. Winning probability, Y: Calculated as simultaneous winning expectation = X / X + Y, assuming that the target general combination is a single winning probability.

  In this embodiment, as shown in FIG. 26, in the normal gaming state that occupies most of the games, the simultaneous winning expectation degree is in the order of Cherry B, Replay C, Watermelon B, Replay B1, Replay B2, Cherry A, and Watermelon A. Highly defined. Of these, the expectation degree of winning for Cherry B is 100%, and winning of the special role will be confirmed simply by winning. In addition, there is a possibility that only the settings 5 and 6 will be won at the same time for the bell, and there is a possibility that only the settings 4 and 6 will be won at the same time for Replay A. , 6 is determined and settings 4 and 6 are determined when Replay A and the special combination are won simultaneously.

  In this embodiment, as shown in FIGS. 8 and 9, the normal gaming state, RT1, RT2, RT3, RT4, BB1 (RB1), BB2 (RB1), BB3 (RB2), BB4 (RB2), BB5 (RB3) ), BB6 (RB3).

  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, where 0000 indicates a normal gaming state, one of RT1 to RT4, 0011 indicates BB1 (RB1), 0101 indicates BB2 (RB1), and 0111 indicates BB3 (RB2 , 1001 indicates BB4 (RB2), 1011 indicates BB5 (RB3), and 1101 indicates BB6 (RB3). The RT flag is 4-bit data, where 0000 indicates the normal gaming state and any of BB1 to BB6, 0001 indicates RT1, 0010 indicates RT2, 0011 indicates RT3, and 0100 indicates RT4.

  As shown in FIG. 9, when the gaming state flag value is 0000 and the RT flag value is 0000, it indicates the normal gaming state, and when the gaming state flag value is 0000 and the RT flag value is 0001. Indicates that it is RT1, and when the gaming state flag value is 0000 and the RT flag value is 0010, it indicates that it is RT2, the gaming state flag value is 0000, and the RT flag value is 0011. Indicates RT3. When the gaming state flag value is 0000 and the RT flag value is 0100, it indicates RT4. When the gaming state flag value is 0011 and the RT flag value is 0000. Indicates BB1 (RB1), and when the gaming state flag value is 0101 and the RT flag value is 0000, it indicates that it is BB2 (RB1). When the flag value is 0111 and the RT flag value is 0000, it indicates BB3 (RB2), and when the gaming state flag value is 1001 and the RT flag value is 0000, it is BB4 (RB2). If the value of the game state flag is 1011 and the value of the RT flag is 0000, it indicates that it is BB5 (RB3). If the value of the game state flag is 1101 and the value of the RT flag is 0000, Indicates BB6 (RB3).

  On the other hand, in the present embodiment, the game state is specified by referring to the value of the game state flag and the value of the RT flag stored in the RAM 507 in the internal lottery, and the lottery is performed using the number of determination values corresponding to the game state. The internal lottery is performed with the winning probability corresponding to the type of game state for the lottery target combination corresponding to the type of game state.

  In the normal gaming state, the specified number of games is consumed at RT1 or RT2, or transition is made after the end of BB1 to BB4. Then, regardless of the number of games since the transition to the normal gaming state, the normal gaming state transitions to RT1 by winning Replay 2, or transitions to RT2 by winning Replay 3, or the special role is elected The process is terminated by shifting to RT4.

  In the normal gaming state, the winning probability of the re-playing role is a normal probability (about 1 / 7.3), and the winning probability of the small role is a normal probability (about 1 / 5.17 to about 1 / 5.87). In the normal gaming state, Replay A, Replay B1, Replay B2, and Replay C are targeted for internal lottery.

  RT1 shifts to the normal gaming state or when Replay 2 wins in RT3. Then, RT1 ends when the game shifts to RT1 and then the seven games determined as the prescribed number of games are digested to shift to the normal gaming state, or the special role is elected and shifts to RT4.

  The probability of winning a re-playing role in RT1 is high (about 1 / 2.17 to about 1 / 2.37), and the winning probability of a small role is a normal probability (about 1 / 5.17 to about 1 / 5.87) It is. Also, in RT1, only replay A and replay B2 are subject to internal lottery, except for the case where a special combination is won simultaneously with replaying combinations.

  RT2 shifts to the normal gaming state or when Replay 3 wins in RT3. Then, RT2 ends when the 9999 game determined as the prescribed number of games is reached after the transition to RT2 and the normal game state is reached, or when the special role is elected and the transition is made to RT4.

  The winning probability of the re-playing role in RT2 is a high probability (about 1 / 1.63), and the winning probability of the small role is a normal probability (about 1 / 5.17 to about 1 / 5.87). Also, in RT2, only replay A is subject to internal lottery, except for the case of winning simultaneously with a special combination among re-playing combinations.

  RT3 transitions after the end of BB5, BB6. Then, regardless of the number of games since the transition to RT3, RT3 transitions to RT1 by winning Replay 2, transitions to RT2 by winning Replay 3, or transitions to RT4 by winning a special role. That's it.

  The probability of winning a re-playing role in RT3 is a normal probability (about 1 / 7.2 to about 1 / 7.3), and a winning probability of a small role is a normal probability (about 1 / 5.17 to about 1 / 5.87) However, the probability that Replay C, which is allowed to win Replay 3 that will shift to RT2, is won alone is higher than the normal gaming state (in the normal gaming state 1/65536 in RT3 about 1 /546.13 to 1 / 992.97). In RT3, only replay A, replay B2, and replay C are subject to internal lottery except for the case where a special combination is won simultaneously with replaying combinations.

  RT4 transitions to the normal gaming state, when a special combination (BB1-6) is won in RT1-3. RT4 ends when the special combination that triggered the transition to RT4 wins and shifts to BB1 to BB6 regardless of the number of games since the transition to RT4.

  In RT4, the special role is not subject to internal lottery, the winning probability of the re-playing role is high (about 1 / 2.17 to about 1 / 2.35), and the winning probability of the small role is the normal probability (about 1 / 5.17 to about 1 / 5.87). In RT4, Replay A, Replay B1, Replay B2, and Replay C are targeted for internal lottery.

  BB1 shifts when BB1 wins at RT4. BB2 shifts when BB2 wins at RT4. BB1, BB2 ends when the total number of medals paid out during BB1 or BB2 exceeds the prescribed number of 465 regardless of the number of games since the transition to BB1, BB2.

  In BB1 and BB2, the special combination and the re-playing combination are excluded from the internal lottery, and the winning probability of the small combination is a high probability (about 1/1).

  BB3 shifts when BB3 wins at RT4. BB4 shifts when BB4 wins at RT4. BB3 and BB4 are ended when the total number of medals paid out during BB3 or BB4 exceeds the prescribed number of 344 regardless of the number of games since the transition to BB3 and BB4.

  In BB3 and 4, the special combination and the re-playing combination are excluded from the internal lottery, and the winning probability of the small combination is a high probability (about 1/1).

  BB5 shifts when BB5 wins at RT4. BB6 shifts when BB6 wins at RT4. BB5 and BB6 are ended when the total number of medals paid out during BB5 or BB6 exceeds the prescribed 105, regardless of the number of games since the transition to BB5 or BB6.

  In BBs 5 and 6, the special combination and the re-playing combination are excluded from the internal lottery, and the winning probability of the small combination is a high probability (about 1/1).

  Of the normal gaming state, RT1 to RT4, BB1 to BB6 are the most advantageous gaming state with the highest medal payout rate per game. Among BB1 to BB6, BB1 and BB2 are most advantageous because the number of medals that can be expected is the largest, BB3 and 4 are advantageous, and BB5 and 6 are advantageous.

  Also, RT1, 2, and 4 out of the normal gaming state RT1 to RT4 can be said to be more advantageous to the player than the normal gaming state or RT3 because the winning probability of the re-gamer is high. In addition, RT2 which is the most advantageous among RT1, 2, 4 and RT2 which continues until the special role is won or the 9999 game is exhausted can be said to be the most advantageous state. In this embodiment, RT2 is also referred to as advantageous RT. On the other hand, RT3 has a higher probability of transitioning to RT2 than the normal gaming state, and can be said to be more advantageous than the normal gaming state in that respect. In this embodiment, RT3 is also called an advantageous RT high-accuracy state. In addition, RT4 is a gaming state in which any special combination is won, that is, a state in which a special combination is won by internal lottery, and in this embodiment, RT4 is also called an internal medium RT.

  Here, the transition state of the game state of the present embodiment will be described. As shown in FIG. 8, when the replay 2 wins in the normal game state that occupies most of the game, the state transitions to RT1. Replay 2 wins at the time of winning Replay B1 or Replay B2 with a high expectation of winning simultaneously with the special role, and the winning probability of the re-playing role increases over 7 games, and shows behavior similar to RT4 when winning the special role At the same time, since it becomes difficult to determine whether or not the special role is won, it also functions as a production RT. RT1 shifts to a normal gaming state when seven games are consumed without winning the special role, and shifts to RT4 (internal RT) when the special role is won.

  When the replay 3 wins in the normal gaming state, it shifts to RT2 (advantageous RT). Replay 3 will be awarded when Replay C is won. At this time, Replay 2 may also be awarded at the same time as Replay 3, but in this case, RT2 (advantageous RT) is not transferred to RT1. Migrate to RT2 (advantageous RT) shifts to the normal gaming state when the 9999 game is digested without winning the special role, and shifts to RT4 (RT inside) when the special role is won.

  When the special combination is won in the normal gaming state, the process shifts to RT4 (internal RT) as in the case where the special combination is won in RT1 (production RT) or RT2 (advantageous RT). RT4 ends when the special combination that has triggered the transition to RT4 wins, and transitions to BB1-6.

  After the end of BB1 to 4, the game state shifts to the normal gaming state, whereas after the end of BB5 and BB6, the state shifts to RT3 (advantageous RT high probability state). In RT3, as in the normal gaming state, when Replay 2 wins, it shifts to RT1 (production RT), and when Replay 3 wins, it shifts to RT2 (advantageous RT), and the special role is won. If you move to RT4 (RT in the inside), if you move to RT1 (RT for production) or if you move to RT2 (advantageous RT), if the special role is not won, It will shift to the normal gaming state again.

  FIG. 27 is a diagram illustrating a configuration of the reel motors 32L, 32C, and 32R. The reel motors 32L, 32C, and 32R are, for example, hybrid type stepping motors, and include a stator 32b and a rotor 32a facing the stator 32b. The rotor 32a has a large number of gear-shaped salient poles (not shown), and permanent magnets magnetized in the same direction as the rotation shaft are incorporated therein.

  The main control unit 41 performs a process of updating the excitation state of each excitation phase φ1 to φ4 in the timer interrupt process (main) described above, and a pulse signal is output from the motor drive circuit 45 accordingly. The reel motors 32L, 32C, 32R receive this pulse signal, and the excitation phases φ1 to φ4 of the stator 32b are excited according to a predetermined procedure, so that each time one pulse is received, a predetermined angle (one step) The rotor 32a is rotated by about 1.07 (360/336) degrees.

  FIG. 28 is a diagram showing a step rate at the time of reel acceleration at the start of the reel motors 32L, 32C, 32R, and FIG. 29 is a timing chart at that time.

  One step is a unit to which one excitation pattern is applied. During constant speed rotation, the rotor 32a rotates by the predetermined angle (about 1.07 (360/336) degrees) described above for each step. Therefore, in the stepping motor of this embodiment, the reel makes one round with a cycle of 336 steps as described above, and since 21 symbols are arranged on the reel, 1 is made every 16 steps. The symbol will move. The excitation pattern is updated by a timer interrupt process (main) performed by the main control unit 41, and the count is the number of timer interrupt processes (main) until the next excitation pattern update. (Count number) × 0.56 ms (interval of timer interrupt processing (main)) is an excitation time (step rate) in which the excitation pattern of the step continues. The number of steps indicates the number of times that the corresponding excitation time is continuously applied. Further, φ1 to φ4 in the figure indicate the respective excitation phases, “ON” indicates the excited state, and “OFF” indicates the demagnetized state.

  As shown in FIG. 29, the main control unit 41 starts rotation of the reel motors 32L, 32C, and 32R in the rotational direction by the 1-2 phase excitation method, which will be described later, from the state where each excitation phase φ1 to φ4 is demagnetized. Start excitation. Specifically, (φ1, φ4) is excited in the first step, and (φ4), (φ4, φ3), (φ3), (φ3, φ2), (φ2), (φ2, In the order of φ1), (φ1)..., the excitation pattern is updated alternately for φ1-φ4 in two phases, one phase, and two phases.

  As shown in FIG. 28, the step rate of the first step is 20.16 ms, the step rate of the second step is 11.20 ms, the step rate of the third to ninth steps is 6.72 ms, and the step rate of the tenth step. Is 4.48 ms, and the step rate of each step is shortened so as to gradually approach the constant speed rotation step rate (2.24 ms). At this time, instead of reducing the step rate uniformly, the reel is smoothly accelerated by interlacing a long step rate and a short step rate and gradually increasing the short step rate. .

  In this embodiment, as shown in FIG. 29, the stop state is shifted to the constant speed state in 25 steps, and thereafter, the 1-2 phase excitation method excitation pattern is updated at a step rate of 2.24 ms. The motor is driven to rotate each reel 2L, 2C, 2R. Specifically, along the rotation direction of the rotor 32a, (φ1, φ4), (φ4), (φ4, φ3), (φ3), (φ3, φ2), (φ2), (φ2, φ1), (φ1 ), (Φ1, φ4)... And the excitation pattern of φ1 to φ4 is alternately updated every two phases, one phase, two phases, one phase, two phases, and the rotor 32a is rotated. Thus, the reels 2L, 2C, 2R are rotated.

  Next, the control of the reel motor when the reel is stopped will be described. There are two types of control of the reel motor when the reel is stopped: normal stop control and low-speed stop control. The former is a control for stopping the reel at the target stop position as soon as possible after detecting the stop operation, that is, the reel is controlled. This is a control to stop the reel in a normal stop mode that requires a time that increases in proportion to the increase in the number of sliding frames as the time to stop.The latter is compared with the normal stop control after detecting the stop operation. Control to slowly stop the reel at the target stop position, that is, the time until the reel stops is required to stop the reel at a specific number of sliding frames (one frame in this embodiment) by normal stop control. The reel is stopped in a special stop mode that requires a time (142.24 to 175.84 ms in this embodiment) that exceeds the time (39.2 to 72.8 ms in this embodiment). That is a control. For this reason, in the latter case, even when the stop operation is performed at the same timing as the normal stop control and stopped at the same stop position, the time required for the reel to stop after the stop operation is increased.

  In this embodiment, the low speed stop control is applied only when one frame is selected as the number of sliding frames when the stop operation is performed. This is because if the low-speed stop control is applied when the number of sliding frames is small, the rotation speed drops rapidly, and the vibration of the reel becomes noticeable. On the other hand, the low-speed stop control is performed when the number of sliding frames is large. This is because, when applied, it becomes difficult to understand the difference from the normal stop control, and in the weight of the stepping motor and the reel applied in this embodiment, one frame is most suitable in the above points. .

  In the normal stop control, as shown in FIGS. 31 and 32, after detecting the stop operation, the constant speed rotation step rate (2.24 ms) is maintained until the brake start position corresponding to the stop position is reached, When the brake start position is reached, a step rate (3.36 ms) longer than the step rate (2.24 ms) during constant speed rotation is applied, the brake is applied to decelerate the rotor 32a, and the next step (4 In the step before step), all-phase excitation for exciting all excitation phases φ1 to φ4 is started. As a result, sudden braking is applied to the rotor 32a, and as a result of overshoot (step out), the rotor 32a stops at the stop position.

  In this embodiment, after all-phase excitation is performed in the normal stop control, it slips by overshooting by 5 steps. Therefore, as shown in FIG. 32, the brake is applied at a step 6 steps before the stop position with respect to the rotation direction. And all-phase excitation is started 5 steps before the stop position.

  In the normal stop control, as shown in FIG. 30, when the stop operation is performed at a timing of 22 to 37 steps before the stop position, that is, one-frame slip in which the later-described low-speed stop control is performed, After the detection, the step rate is controlled to be the same as the constant speed rotation of 2.24 ms for 16 to 31 steps, and in the next step, the step rate is controlled to 3.36 ms longer than the constant speed rotation. Since it is controlled by excitation, it takes 39.2 ms to 72.8 ms to detect all phases after detecting the stop operation.

  In the low speed stop control, as shown in FIG. 34 and FIG. 35, after the stop operation is detected, the constant speed rotation step rate (2.P) is reached until the brake start position corresponding to the stop position is reached in the same manner as in the normal stop control. 24 ms), but a step rate (4. 24 ms) longer than the step rate (2.24 ms) at constant speed rotation from the brake start position positioned further forward than the brake start position in the normal stop control. 48 ms) is applied and the brake is applied to start the deceleration of the rotor 32a. At this time, as shown in FIG. 33, the step rate is not increased uniformly, but a long step rate is applied alternately while alternately interlacing a long step rate and a short step rate, thereby smoothly rotating the rotor. 32a is decelerated.

  Then, the step rate is gradually increased toward the stop position to decelerate, and all-phase excitation is started at the stop position. Thus, the rotor 32a that is gradually decelerated stops at the stop position without overshooting (step out). Since all-phase excitation is performed in the low-speed stop control as described above and then stopped without overshooting, all-phase excitation is started at the stop position.

  In the low speed stop control, as shown in FIG. 33, after the stop operation is detected, the step rate is controlled to 2.24 ms, which is the same as the constant speed rotation, for 0 to 15 steps. 48 ms × 1, 2.24 ms × 3, 4.48 ms × 1, 2.24 ms × 2, 4.48 ms × 5, 6.16 ms × 1, 6.72 ms × 2, 8.4 ms × 1, 8.96 ms × 2, 9.52 ms × 1, 11.76 ms × 1, 14.56 ms × 1, 17.92 ms × 1 and then controlled to all phase excitation. It takes 142.24 ms to 175.84 ms to phase excitation. When stopping at one frame slip in normal stop control, the time required for all-phase excitation after detection of the stop operation is 39.2 ms to 75.04 ms, even when stopping at the same stop position with the same one frame slip As compared with the normal stop control, it takes a long time to stop after the stop operation is detected.

  As described above, in this embodiment, even when the stop operation is performed at the same timing and the stop operation is performed at the same position, when the low speed stop control is performed, the reel is decelerated compared to the normal stop control. The time required from the start to the stop becomes longer, and the stop position is reached slowly, so that the stop mode can be diversified.

  Even when low-speed stop control is performed, control is performed at the same step rate as constant-speed rotation until the brake start position is reached after a stop operation is detected. Regardless of the number of steps in which the operation is detected, if the number of sliding frames is the same, low-speed stop control can be performed with common control, and control can be prevented from becoming more complicated than necessary.

  The low-speed stop control shown in the present embodiment is a control method other than the above-excited control method as long as it is a control for slowly stopping the reel at a target stop position as compared with the normal stop control after detecting the stop operation. It may be performed by the control. For example, by making the excitation pattern different from the constant speed rotation at a stage earlier than the normal stop control, for example, by exciting the three excitation phases while keeping the excitation phase to be demagnetized originally excited, After decelerating the reel, it may be possible to lengthen the time required to stop than usual by performing all-phase excitation.

  In this embodiment, both the normal stop control and the low-speed stop control are configured to continue all-phase excitation for the same time after the start of all-phase excitation. The inertial force at the start of all-phase excitation is also weak, and the reel can be stopped reliably without continuing all-phase excitation for the same time as the normal stop control. The time until all the excitation phases are turned off after the start of all-phase excitation may be set shorter than the control.

  For example, when the hopper motor 34b is accompanied by a medal payout, the voltage is insufficient and the medal payout is waited until the all-phase excitation is released. As described above, the normal stop control is performed in the low speed stop control. By setting the all-phase excitation time shorter or not performing all-phase excitation, the time until the medal payout operation can be shortened when performing the low-speed stop control.

  Next, the control content executed by the main control unit 41 in connection with the low speed stop control will be described.

  FIG. 39 is a flowchart showing the control contents of the game process executed by the main control unit 41.

  In the game process, a BET process (Sd1), an internal lottery process (Sd2), a reel rotation process (Sd3), a winning determination process (Sd4), a payout process (Sd5), and a game end process (Sd6) are sequentially executed. When the end-time process ends, the process returns to the BET process again.

  In the BET process in the step of Sd1, the process waits in a state where the bet number can be set, sets a predetermined number of bets according to the gaming state, and executes a process of determining the bet number when the start switch 7 is operated. To do.

  In the internal lottery process in step Sd2, a random number for internal lottery is extracted simultaneously with the start of the game by the detection of the start switch 7 in step Sd1, and the winning of each above-described combination is permitted based on the extracted random number value. Process to determine whether or not. In this internal lottery process, a winning flag is set in the RAM 507 based on each lottery result.

  In the reel rotation process in the step of Sd3, the process of rotating each reel 2L, 2C, 2R and the operation of the corresponding reel 2L, 2C, 2R in response to the operation of the stop switch 8L, 8C, 8R detected by the player are detected. A process for stopping the rotation is executed. In the reel rotation process, a low-speed stop determination process for determining whether or not to execute the low-speed stop control before starting the reel rotation is executed.

  In the winning determination process in the step Sd4, when it is determined in the step Sd3 that the rotation of all the reels 2L, 2C, and 2R is stopped, the winning is determined according to the display result derived for each reel 2L, 2C, and 2R. A process of determining whether or not it has occurred is executed.

  In the payout process in step Sd5, when it is determined that a prize is generated in step Sd4, processing such as addition of credits and payout of medals is performed based on the number of payouts according to the win.

  In the game end process in the step of Sd6, a process of setting a gaming state in preparation for the next game is executed.

  FIG. 40 is a flowchart showing the control contents of the reel rotation process executed by the main control unit 41 in step Sd3.

  In the reel rotation process, first, it is determined whether or not a wait time (about 4.1 seconds in this embodiment) has elapsed since the reel rotation start time of the previous game (Si1), and the wait time must have elapsed. For example, it waits until the wait time elapses.

  If the wait time has elapsed in the Si1 step, a new wait time is set (Si2).

  Next, after performing a low-speed stop determination process for determining whether or not to execute the low-speed stop control (Si3), the reel motor is set to start rotating, and the reel starts rotating (Si4). Then, a sliding frame number setting process for setting the number of sliding frames in the virtual sliding frame table for each rotating reel is performed (Si5), and a setting at the time of completion of stop preparation is performed (Si6). As a result, the stop operation can be validated, and then the stop operation becomes valid when a constant-speed rotation of the reel is detected in the processing at the time of passing through the origin of a timer interrupt process described later.

  Next, it is determined whether or not an operation of any one of the stop switches 8L, 8C, 8R is detected (Si7). If no operation of any stop switch is detected, a reel rotation error (over a certain period of time). Then, it is determined whether or not an error determined when the reel reference position is not detected by the reel sensor 33 (Si8). If no reel rotation error has occurred, an insertion error (medal insertion) is further performed. Whether or not a medal insertion was detected during a period other than the permitted period, and whether or not a payout error (medal payout was detected during a period other than the permitted period) (Error determined in the case) is determined (Si9, Si10), and any error in the steps of Si8 to Si10 If raw also is determined, the process returns to the step of Si7.

  If it is determined that a loading error has occurred in the Si9 step, or if a dispensing error is determined in the Si10 step, an error code indicating a loading / dispensing error during reel rotation is set in the register (Si11). ), And shifts to error processing (Si12). When the error is released, the process returns to the Si6 step again.

  If it is determined in step Si8 that a reel rotation error has occurred, an error code indicating a reel rotation error is set in the register (Si13), and the process proceeds to error processing (Si4). Along with this, the rotation of the reels is also temporarily stopped. When the error is released, the process returns to the Si4 step again and the reel rotation is resumed.

  If any stop switch operation is detected in the Si7 step, the number of steps from the reel reference position at that time in the reel motor corresponding to the stop switch (the number of steps to be the stop operation position) is calculated. After obtaining and setting the work corresponding to the stop reel (Si15), the process waits until the rotation of the reel corresponding to the stop operation stops (Si16).

  Then, when the rotation of the reels corresponding to the stop operation is stopped, it is determined whether or not all the reels are stopped (Si17). If all the reels are not stopped, the process returns to the Si5 step, and all the reels are If it is stopped, the reel rotation process is terminated and the process returns to the flowchart of FIG.

  As described above, in the reel rotation processing, after the rotation of the reels 2L, 2C, and 2R is started, the rotation of the reels for which the stop operation has not been detected is continued until the operation of the stop switches 8L, 8C, and 8R is detected. Then, 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.

  FIG. 41 is a flowchart showing the control content of the low speed stop determination process performed by the main control unit 41.

  In the low-speed stop determination process, first, it is determined whether or not it is during RT1 or RT4 (Si51). Next, if it is during RT1 or RT4, it is determined whether or not Replay A is won (Si52), and if Replay A is won, the process proceeds to Step Si55.

  If Replay A is not won in the step of Si52, it is determined whether BB1 or BB2 is won (Si53). If BB1 or BB2 is won, it is further determined whether Bell is won. (Si54) If the bell is elected, the process proceeds to Si55.

  In the step of Si55, it is determined whether or not the special role is confirmed. In this embodiment, if a special role is won at the same time as Replay B1, Replay B2, and Replay C, after 8 games, if a special role is won at the same time as Watermelon A, Watermelon B, Cherry A, and Cherry B, 4 games are won. After that, in other cases, a command is sent to the sub-control unit 91 instructing to confirm the special role after 5 games after the special role is won. Regardless of whether the notification is made or not, the notification of the special role confirmation is instructed, and at this time, a fixed notification flag indicating that the fixed notification has been completed is set in the RAM 507. Then, in the step of Si55, it is determined whether or not the special combination notification has already been performed depending on whether or not the fixed notification flag is set.

  If it is determined in step S55 that the special combination is not confirmed, a low speed stop lottery is performed to determine whether or not to perform the low speed stop control with the probability shown in FIG. 42 (Si56).

  Then, it is determined whether or not the low speed stop control is won (Si57). If it is determined that the low speed stop control is won, a low speed stop control flag indicating the low speed stop control is set (Si58).

  In the Si51 step, neither RT1 nor RT4, in the Si53 step, neither BB1 nor BB2 has been won, in the Si54 step, the bell has not been won, in the Si55, after the special role is confirmed If the low speed stop control is not won in the step of Si57, the process is terminated at that time, and the low speed stop control is not performed in the game.

  In the low-speed stop determination process, during the replay A winning in RT1, during RT4, that is, during the replay A winning while the special role winning flag is carried over, during the bell winning during the RT4 and carrying the winning flag of BB1 or BB2 By performing the low speed stop lottery on the condition that the special role confirmation notification is not performed, and winning in the low speed stop lottery, it becomes possible to perform the low speed stop control in the game.

  In particular, in the present embodiment, replay A in which settings 1 to 4 are not simultaneously won with special roles and settings 5 and 6 are rarely simultaneously with special roles. A low-speed stop lottery will be performed only at the time of winning a bell that is not won, and even in settings 4 and 6, which are rarely won simultaneously with special roles. For this reason, the low speed stop control is performed in the state where the special role is elected during the carryover of the special role, and the slow stop control is rarely performed in the established game where the special role is elected. .

  In the low speed stop lottery, as shown in FIG. 42, the probability of winning the low speed stop control when Replay A is won during RT1 (settings 1-3: 3.9%, settings 4, 5: 4.7%, settings 6: The probability of winning the low-speed stop control (setting 1 to 6: 19.5%) at the time of Replay A winning during RT4, that is, Replay A winning while carrying a special role, is set higher than 5.5%) . In addition, the probability of winning the low speed stop control when the Replay A is won during RT1 is set higher in the high setting range (settings 4 to 6) than in the low setting range (settings 1 to 6).

  Further, when RT4 and BB1 or BB2 are won, there is a low probability (setting 1 to 6: 3.1%), but the low speed stop control is won even when the bell is won. That is, when the bell is won, the low-speed stop control is performed, so that the most advantageous winning of BB1 or BB2 among the BBs is decided.

  When the low-speed stop control flag is set in the low-speed stop determination process, the low-speed stop control is applied if one frame is selected as the number of sliding frames when the reel is stopped by a stop operation thereafter.

  In addition, when the low speed stop control flag is not set or when the low speed stop control flag is set, but 0, 2, 3, and 4 are selected as the number of sliding frames, the reel is stopped by the stop operation. In this case, the normal stop control is applied.

  As described above, since the low speed stop control flag is not set during the BB or after the special role is confirmed, the low speed control flag is not set even during the BB or after the special role is confirmed. Stop control is never performed.

  FIG. 43 is a flowchart showing the control contents of the sliding frame number setting process executed by the main control unit 41 in the step of Si5.

  First, in the sliding frame number setting process, it is determined whether or not it is the first stop, that is, whether or not all the reels are rotating (Si102). If it is the first stop, the process proceeds to Si102.

  In step S102, the table index is referred to, the sliding frame number data of the unstopped reel corresponding to the result of the internal lottery (stopped reel and its stop position if other than the first stop) is selected, and the selected slip is selected. The frame number data is expanded to perform the sliding frame number data expansion processing for storing the number of sliding frames for each stop operation position of the unstopped reel in the virtual sliding frame table, and the process returns to the flowchart of FIG.

  If it is not the first stop in the Si101 step, the process proceeds to the Si103 step to determine whether the internal lottery result is a specific result (BB1 to 4 in this embodiment). If it is determined that the lottery result is a specific result, it is determined whether or not the first stop reel is the left reel (Si104). If the first stop reel is the left reel, the left is further left. A specific stop position in which the reel stop position is determined according to a specific result (in this embodiment, the lower 17 stop position, the lower 11 stop position, the lower 7 stop position, and the lower 2 stop position) It is determined whether or not the position is the stop position of the lower stage 0 (Si105).

  If it is determined in step S105 that the stop position of the left reel is a specific stop position determined according to a specific result, the process proceeds to step S102, and the reels that have been stopped as a result of the internal lottery. And the slip frame number data of the unstopped reel corresponding to the stop position, the selected slip frame number data is expanded, and the slip frame number for each stop operation position of the unstopped reel in the virtual slide frame table is stored. The frame number data expansion process is performed, and the process returns to the flowchart of FIG.

  On the other hand, if it is determined that the result of the internal lottery is not a specific result in the step of Si103, or if it is determined that the first stop reel is not the left reel in the step of Si104, the stop position of the left reel is determined in the step of Si105. Is determined not to be a stop position determined according to a specific result, the process proceeds to step Si106, and for each stop operation position of an unstopped reel, a stop position with a sliding frame number of 0 to 4 is used. A stop position search process is performed in which the winning positions are aligned on the winning line, the stop positions where the non-winning roles are not aligned on the winning line are searched, and the number of sliding frames as the stopping positions obtained by the search is stored in the virtual sliding frame table. Then, after performing the sliding frame number setting process, the process returns to the flowchart of FIG.

  FIG. 44 is a flowchart showing the control content of the stop position search process executed by the main control unit 41 in the step of Si105.

  First, in the stop position search process, a reel to be processed is set in step Si301. That is, among the rotating reels, a reel that has not yet been processed is set as a target reel, and the process proceeds to step Si302.

  In the step of Si302, a stop position pointer indicating a stop position to be processed is set to 0, and whether or not an abnormal winning occurs when the process proceeds to the step of Si303 and reaches the stop position to be processed. The virtual winning determination is performed, and the process proceeds to step S304 to determine whether the result of the virtual winning determination is an abnormal winning.

  If it is not an abnormal winning in the step of Si304, the process proceeds to the step of Si305, and further prohibition position determination is performed to determine whether or not the stop prohibition position is reached. It is determined whether or not.

  If it is not the stop prohibition position in the step of Si306, the process proceeds to the step of Si308, and if it is determined that the abnormal winning is obtained in the step of Si304, or if it is determined that the stop prohibition position is set in the step of Si306, the step of Si307 is performed. Then, after setting a stop prohibition position flag indicating a stop prohibition position corresponding to the stop position indicated by the stop position pointer, the process proceeds to step Si308.

  In the step of Si308, the stop position pointer is advanced by 1 and the process proceeds to the step of Si309 to determine whether or not the stop position pointer is 21, and if the stop position pointer is not 21, the process returns to the step of Si303 to stop. If it is determined that the pointer is 21, that is, the determination for all the area numbers has been completed, the process proceeds to step S310.

  In the step of Si310, the stop operation position pointer indicating the stop operation position to be processed is set to 0, and the process proceeds to the step of Si311 to determine the order corresponding to the winning combination (especially 1 in the case of replay A and bell winning). In this embodiment, the number of sliding frames is acquired by applying the order of 1 → 0 → 2 → 3 → 4), and the process proceeds to step S312.

  In step Si312, the stop position based on the number of sliding frames acquired in Si311 is acquired, and the process proceeds to step Si313 to determine whether the acquired stop position is a stop prohibition position, that is, whether a stop prohibition position flag is set. To do.

  If it is determined in the Si 313 step that the position is the stop prohibited position, the process returns to the Si 311 step. If it is determined that the position is not the stop prohibited position, the process proceeds to the Si 314 step.

  In the step of Si314, it is determined whether or not the winning combination is aligned on the winning line when the acquired stop position is reached. If the winning combination is not aligned on the winning line, the process proceeds to the step of Si315, and the winning line is selected on the winning line. If it is determined that the combination is complete, the process proceeds to step Si316.

  In the step of Si315, it is determined whether or not the stop positions are compared for all the sliding frame numbers from 0 to 4, and if the comparison of the stopping positions is completed for all the sliding frame numbers from 0 to 4, the process of Si316 is completed. Proceed to the step, and if the comparison of the stop positions is not completed for all the sliding frames from 0 to 4, the process returns to the Si311 step.

  In the step of Si316, last in the step of Si312 corresponding to the corresponding stop operation position (area number indicated by the stop operation position pointer) of the corresponding reel (reel set as the target reel) in the virtual sliding frame number table. The acquired number of sliding frames at the stop position is stored, and the process proceeds to step Si317. In addition, when the number of sliding symbols that become the stop position acquired last is the stop prohibiting position, the number of sliding symbols that are not the stopping prohibition position among the number of sliding symbols that become the stopping position acquired before that is stored. .

  In the Si317 step, the stop operation position pointer is advanced by 1 and the process proceeds to the Si318 step to determine whether or not the stop operation position pointer is 21, and if the stop operation position pointer is not 21, the process returns to the Si311 step. If the stop operation position pointer is 21, that is, if it is determined that all the region numbers 0 to 20 have been determined, the process proceeds to step Si319.

  In step S319, it is determined whether there is an unprocessed rotating reel. If there is an unprocessed rotating reel, the process returns to step Si301. If there is no unprocessed rotating reel, the number of sliding frames is updated. To return to the flowchart shown in FIG.

  45 and 46 are flowcharts showing the control contents of the timer interrupt process (main) executed by the main control unit 41 by interrupting and executing the game process at intervals of 0.56 ms.

  In the timer interruption process, first, interruption is prohibited (Sk1). That is, the execution of another interrupt process during the execution of the timer interrupt process is prohibited. Then, the register in use is saved in the stack area (Sk2).

  Next, the branch counter for identifying the timer interrupt to be executed in the timer interrupt process is advanced by 1 from the four types of timer interrupts 1 to 4 (Sk3). In the step of Sk3, 1 is added when the branch counter value is 0 to 2, and is updated to 0 when the counter value is 3. That is, the branch counter value loops in the order of 0 → 1 → 2 → 3 → 0... Each time the timer interrupt process is executed.

  Next, referring to the counter value for branching, it is determined whether it is 2 or 3, that is, timer interrupt 3 or timer interrupt 4 (Sk4), and if it is not timer interrupt 3 or timer interrupt 4, that is, timer interrupt In the case of 1 or timer interrupt 2, it is checked whether the reel motors 32L, 32C, 32R are started or whether they are rotating at a constant speed, and whether the reel motors 32L, 32C, 32R are started or are rotating at a constant speed. For example, the motor phase signal output process for outputting the phase signal data changed in the motor step process of Sk8 described later and the phase signal data changed in the final stop process of Sk24 described later is executed (Sk5).

  Next, referring to the counter value for branching, it is determined whether or not it is 1, that is, timer interrupt 2 (Sk6). If it is not timer interrupt 2, that is, timer interrupt 1, the reel motor Reel start processing (Sk7) for controlling the step time interval when starting 32L, 32C, 32R, motor step processing (Sk8) for changing phase signal data of the reel motors 32L, 32C, 32R, reel motors 32L, 32C After the stop of 32R, the motor phase signal standby process (Sk9) for changing the phase signal to one-phase excitation after a certain time has been sequentially executed, and then the register saved in the stack area at Sk2 is restored (Sk20). The interrupt prohibited in the step is permitted (Sk21), and the process returns to the state before the interrupt.

  In the case of timer interrupt 2 in the step of Sk6, LED dynamic display processing for dynamically lighting various indicators (Sk10), control signal output processing for outputting data such as lighting signals of various LEDs to the output port, etc. (Sk11), a random number update process for updating various software random numbers (Sk12), a time counter update process for updating various time counters (Sk13), an operation detection command is generated at the transmission timing of the operation detection command, and the serial communication circuit 511 After sequentially executing the command transmission process (Sk14) to be transmitted to the sub-control unit 91 by transfer and the external output signal update process (Sk15) to update the external output signal, the register saved in the stack area at Sk2 is restored ( (Sk20), and interrupts prohibited in the step of Sk1 are permitted (Sk 1), it returns to the interrupt before processing.

  If it is timer interrupt 3 or timer interrupt 4 in the step of Sk4, the branch counter value is further referred to to determine whether it is 3 or not, ie, timer interrupt 4 (Sk16). If it is not interrupt 4, that is, timer interrupt 3, port input processing (Sk17) for inputting detection data of various switches from the input port, passing the origin of the reels 2L, 2C, 2R during rotation (reel reference) (Passing position) is detected, the occurrence of a reel rotation error is detected, whether stop preparation is completed (stop preparation completion code is set), stop preparation is complete, and If it is rotating at high speed, the process at the time of passing through the origin (Sk18) that validates the operation of the stop switch corresponding to the rotating reel, and the various scans based on the detection signals of the various switches. After sequentially executing the switch input determination process (Sk19) for determining whether or not the switch satisfies the detection condition, the register saved in the stack area in Sk2 is restored (Sk20), and the interrupts prohibited in the Sk1 step Is permitted (Sk21) and the process returns to the state before the interruption.

  If the timer interrupt is 4 in the step of Sk16, the stop stored in the work on the stop reel is stored when the stop operation position is stored in the work on the stop reel in accordance with the detection of the stop switches 8L, 8C, 8R. Determine the stop position from the operation position, calculate how many steps should be stopped, and if the low speed stop control flag is set, execute the low speed stop control if the number of steps corresponds to one frame Stop switch process (Sk22), the number of steps until the stop calculated in the stop switch process is counted, and the brake is stopped by controlling the excitation time according to the normal stop control and the low speed stop control toward the stop timing. The process (Sk23) and the final stop process (Sk24) in which all phases are excited when the stop time step is reached are sequentially executed, and then in Sk2. Returning the registers saved in the stack area (SK20), allow interruption prohibited at step Sk1 (SK21), return to the process before the interrupt process.

  FIG. 47 is a flowchart showing the control content of the stop switch process executed by the main control unit 41 in the timer interrupt 4 of the timer interrupt process described above.

  In the stop switch process, it is first determined whether or not a stop operation position has been set for the work on the corresponding reel for all reels in the order of left, middle, and right, that is, whether a stop operation has been detected (Sk101, Sk102) If no stop operation has been detected for all reels, the stop switch process is terminated and the process returns to the flowchart of FIG.

  Further, if any reel stop operation is detected in step Sk101, the process proceeds to step Sk103.

  In step Sk103, the virtual sliding frame table corresponding to the reel is referred to, and the region number serving as the stop position is specified from the region number including the step number of the stop operation position set for the work corresponding to the stop reel. .

  Next, it is determined whether or not the low speed stop control is won in the low speed stop lottery, that is, whether or not the low speed stop control flag indicating the low speed stop control is set (Sk104). If it is determined in step Sk104 that the low speed stop control has not been won, the stop switch process is terminated and the process returns to the flowchart of FIG.

  When it is determined that the low speed stop control is won in the step of Sk104, it is determined whether or not the number of steps specified in the step of Sk103 is the number of steps corresponding to one frame (22 to 37) (Sk105). . If the number of steps does not correspond to one frame, the stop switch process is terminated and the process returns to the flowchart of FIG.

  If the number of steps corresponds to one frame in the step of Sk105, it is determined whether or not the low speed stop control has already been executed in the game (Sk106). Whether or not the low-speed stop control has already been executed is determined based on whether or not an executed flag to be described later is set. If it is determined in step Sk106 that the low speed stop control has already been executed, the stop switch process is terminated and the process returns to the flowchart of FIG.

  If the low speed stop control has not been executed at the step of Sk106, a low speed stop execution flag for instructing execution of the low speed stop control is set in the RAM 507, and an executed flag indicating that the low speed stop control has been executed is stored in the RAM 507. After setting (Sk107, Sk108), the stop switch process is terminated, and the process returns to the flowchart of FIG.

  When the low speed stop execution flag is set in the stop switch process, the excitation time is controlled according to the low speed stop control in the subsequent stop process.

  Further, in the stop switch process, even when the low speed stop control flag is set, if the low speed stop control is already executed in the game, the low speed stop control is not instructed. Thus, when the low speed stop control is executed on any of the reels, the low speed stop control is not executed on the subsequent reels. Note that when low-speed stop control is executed, if the low-speed stop control flag is cleared and the low-speed stop control is executed for any reel, the low-speed stop control is not executed for the subsequent reels. It is good also as a structure to do.

  As described above, in the slot machine 1 of the present embodiment, the normal stop control as the stop control when stopping the reel, and the time required to stop the reel after the stop operation is longer than the normal stop control. Low-speed stop control.

  Since this low-speed stop control is the same as the normal stop mode except that the reel stop speed is slow, the player is likely to miss that the low-speed stop control has been performed.

  In addition, in this embodiment, the general role that can be won simultaneously with the special role has a configuration that suggests that the special role may have been won in the game. In the case of applying as an effect suggesting the possibility of winning, if low speed stop control is performed at the time of winning a general role that can be won simultaneously with the special role, after the low speed stop control has already been completed at the time of winning the general role In addition, it is difficult for the player to recognize that the low speed stop control has been performed.

  On the other hand, in this embodiment, the low speed stop control is performed in a state where the special combination is won, in RT4, the setting 1-4 does not win the special combination at the same time. Replay A, which is rarely won at the same time as a special role, in settings 1 to 3, 5 will not win at the same time as a special role, and only at the time of winning a bell that will not be won at the same time as settings 4 and 6 It is. In other words, a game in which the winning flag for the special role is carried over after the winning game, rather than a winning game that may indicate that the possibility of winning the special role is high, such as when winning a replay 2 or 3 Since the low-speed stop control is performed at a higher rate, the player pays attention to the occurrence of an event that suggests that the special role is highly likely to be won, such as a replay 2 or a replay 3 win in the established game. The low-speed stop control is performed at a high rate in the game after the carry-over of the special role, and the player can be effectively recognized that the low-speed stop control has been performed. It is possible to effectively enhance the interest of the player, and the low-speed stop control improves the player's expectation that is heightened by the occurrence of an event that suggests that the possibility of winning a special role is high. It can also be continued.

  Also, in this embodiment, when the special role is not won, the low speed stop control is performed only when Replay A is won, while when the special role is won, it is added when Replay A is won. When the bell is elected, the low speed stop control is performed. When the special role is elected, not only the opportunity for the low speed stop control to be increased but also the bell with the low speed stop control. Can be recognized by winning the special role.

  In this embodiment, the low speed stop control is performed at the time of winning Replay A or Bell, which is rarely won at the same time as the special role, but Watermelon A, Watermelon B, Cherry A, Cherry B, Replay B1. It is also possible to adopt a configuration in which low-speed stop control can be performed in a formation game in which an event that suggests the possibility of winning a special role occurs, such as when Replay B2 or Replay C is won. However, after the established game, the game where the special role is carried over is configured so that the low-speed stop control is performed at a higher rate, so that the player pays attention to the occurrence of an event that suggests the possibility of winning the special role. The low-speed stop control will be performed at a high rate in the game after the carryover of the special role, and the player will be effectively recognized that the low-speed stop control has been performed. Therefore, it is possible to effectively enhance the interest of low-speed stop control, and to maintain the player's expectation enhanced by the occurrence of an event suggesting the possibility of winning a special role by low-speed stop control. it can.

  In addition, low speed stop control is performed in a formed game in which an event suggesting the possibility of winning a special role occurs, such as when winning watermelon A, watermelon B, cherry A, cherry B, replay B1, replay B2, and replay C. In the structure to be obtained, whether the special role is won at the time of winning of watermelon B, cherry B, replay B1, replay B2, and replay C, where the expectation of winning the special role is higher than when winning watermelon A and cherry A Regardless of whether or not, a configuration in which the low-speed stop control is not performed, or a configuration in which the low-speed stop control is performed in a lower ratio than when the watermelon A and the cherry A that are not expected to win special roles is selected is preferable. , By adopting such a configuration, when "Watermelon-Watermelon-BAR" is aligned and the winning of watermelon B is suggested, in all reels If “Cherry” is stopped on the winning line, Cherry B ’s winning is suggested, Replay 2 ’s winning suggests Replay B1 or Replay B2 ’s winning, Replay 3 ’s winning is Replay C ’s winning The occurrence of events that can be expected to win special roles and low-speed stop control by focusing on the occurrence of events that can be expected to win special roles, such as It can be prevented that the expectation for winning is lost.

  In addition, low speed stop control is performed in a formed game in which an event suggesting the possibility of winning a special role occurs, such as when winning watermelon A, watermelon B, cherry A, cherry B, replay B1, replay B2, and replay C. In the structure to obtain, special chances of winning a general role such as Replay B1, Replay B2, etc. are as high as 1/100 or higher, and the ratio of simultaneous winning special roles is also very high as 1/5 or higher. Regardless of whether or not the winning combination is won, low-speed stop control is not performed, or the proportion of low-speed stopping control performed is low compared to when winning a watermelon A or cherry A that cannot be expected to win special roles. It is preferable to have a configuration, and even if it is an event that can be expected with a high probability of winning the special role, it will be slow when an event with a high frequency occurs. By not performing stop control, it is possible to enhance the rarity of the slow stop control.

  Further, in this embodiment, when it is determined that the low speed stop control is to be performed, when the low speed stop control is performed for any of the reels, the low speed stop control is not performed for the remaining reels thereafter. It has become. This is because, for example, when low speed stop control is similarly performed on all reels, it is difficult to identify whether low speed stop control is performed or normal stop control is performed. When the low speed stop control is performed on any of the reels as described above, the normal stop control and the low speed stop control are always mixed by not performing the low speed stop control for the remaining reels. By doing so, the difference becomes clear and the player can be surely recognized that the low-speed stop control has been performed.

  In this embodiment, when the low speed stop control is performed on any one of the three reels, the low speed stop control is not performed on the other reels, but the low speed stop is performed on a plurality of reels. The configuration may be such that the control is performed, and in such a configuration, the possibility of winning the special role suggested according to the number of reels for which the low speed stop control is performed may be changed.

  Also, in this embodiment, during the BB or after the special role is confirmed and notified, the period until the special combination wins, that is, the period during which no low speed stop control is performed suggests that the low speed Stop control is not performed, and it is possible to prevent the digestion efficiency of the gaming state from being reduced by performing the low speed stop control during such a period.

  In this embodiment, the main control unit 41 instructs the sub-control unit 91 to notify the sub-control unit 91 of the special combination confirmation. In such a configuration, the sub-control unit 91 is instructed to notify the special combination. After that, the low-speed stop control flag is not set, and after the special role notification, the low-speed stop control is not performed even if the target role is won. This is not the case in the configuration in which the sub-control unit 91 independently determines the final notification, and the low-speed stop control is performed regardless of whether or not the final notification of the special role has already been performed after the special role is won. The structure to obtain may be sufficient.

  However, even in such a configuration, the number of games (for example, 10 games after the winning of the special role) in which the notification of the special role is reliably performed on the sub-control unit 91 side after the winning of the special role is performed. After the elapse of time, even if the target role is won, the low speed stop control is not performed, so that the low speed stop control is not performed even if the low speed stop control is performed. Since the low-speed stop control is performed in such a period, it is possible to prevent the digestion efficiency of the gaming state from being lowered.

  The sub-control unit 91 according to the present embodiment executes a winning effect for notifying that the winning combination is emphasized by highlighting the winning combination when any winning combination is won on any winning line.

  The winning effects include winning effects AC that emphasize the winning combination by changing the lighting state of the reel LED 55 after all reels are stopped.

  In the winning effect A, as shown in FIG. 48 (a), the reel LEDs 55 other than the area where the constituent symbol of the winning combination is stopped are turned off, and the reel of the area where the constituent symbol of the winning combination is stopped. This is a winning effect that emphasizes the winning combination in a lighting mode in which the LED 55 is blinked.

  As shown in FIG. 48 (b), the winning effect B turns off the reel LED 55 in the area where the constituent symbol of the winning combination is stopped and reels other than the area where the constituent symbol of the winning combination is stopped. This is a winning effect that emphasizes the winning combination in a lighting mode in which the LED 55 is blinked.

  As shown in FIG. 48 (c), the winning effect C includes a reel LED 55 in the area where the constituent symbol of the winning combination is stopped, and a reel LED 55 other than the area where the constituent symbol of the winning combination is stopped, It is a winning effect that emphasizes the winning combination in a lighting mode in which are alternately flashed.

  Whether or not to execute any of the winning effects A to C when winning a winning combination is determined by a winning effect selection lottery performed by the sub-control unit 91 when winning.

  In the prize-winning effect selection lottery, in particular, the low-speed stop control in the game regardless of whether or not the low-speed stop control is performed during the replay A winning or the bell winning in which the above-described low-speed stop control may be performed. One of the winning effects A to C is selected with a probability corresponding to whether or not the winning is made. That is, even when the low-speed stop control is won but the low-speed stop control is not performed, the probability of winning the low-speed stop control is applied.

  Further, the RAM 91c is assigned with a low speed stop control counter indicating the percentage that the low speed stop control is won and the low speed stop control is not performed, and the value of the low speed stop control counter is greater than 0 or less than 0. Depending on whether or not the low-speed stop control is won and the ratio at which the low-speed stop control is not performed can be specified or less.

  In this embodiment, when the low speed stop control is won and the low speed stop control is performed, the value of the low speed stop control counter is incremented by 2, while the low speed stop control is won and the low speed stop control is performed. If not performed, the value of the low speed stop control counter is decremented by 1, and the low speed stop control counter is controlled according to whether the value of the low speed stop control counter exceeds 0 or less than 0. It is possible to specify whether or not the ratio of winning and the low speed stop control not being performed is 1/3 or less.

  In the winning effect selection lottery, particularly when the low speed stop control is won, the winning effects A to C are obtained with a probability corresponding to whether the value of the low speed stop control counter is greater than 0 or less than 0. Either one is selected.

  When the value of the low-speed stop control counter exceeds 0, that is, when the low-speed stop control is won and the ratio that the low-speed stop control is not performed exceeds 1/3, the replay A is won and the normal stop control is executed. When applied, winning effect A is selected with a probability of 95%, winning effect B with a probability of 5%, winning replay A, and when slow stop control is applied, winning effect A is 50%. When winning effect B is selected with a probability of 45% and winning effect C is selected with a probability of 5%, winning the bell and normal stop control is applied, winning effect A is 95% and winning effect B is 5%. When the bell is won and the low speed stop control is applied, the winning effect A is selected with a probability of 70%, the winning effect B is 28%, and the winning effect C is selected with a probability of 2%.

  In addition, when the value of the low speed stop control counter is 1 or less, that is, when the low speed stop control is won and the rate at which the low speed stop control is not performed is 1/3 or less, the replay A is won and the normal When stop control is applied, winning effect A is selected with a probability of 95% and winning effect B is selected with a probability of 5%. When replay A is won and low speed stop control is applied, winning effect A Is 20%, winning effect B is 70%, winning effect C is selected with a probability of 10%, winning the bell and normal stop control is applied, winning effect A is 95%, winning effect B Is selected with a probability of 5%, and when winning the bell and the low speed stop control is applied, the winning effect A is selected with a probability of 50%, the winning effect B is 45%, and the winning effect C is selected with a probability of 5%. Is done.

  Thus, in the winning effect selection lottery, the low speed stop control is performed in the game regardless of whether or not the low speed stop control is performed during the replay A winning or the bell winning in which the low speed stop control may be performed. When any of the winning effects A to C is selected with a probability according to whether or not the winning is won, and when the low speed stop control is performed, the winning effect is compared with the case where the normal stop control is performed. It is determined that the ratio of selection of winning effects B and C among A to C is high, and the winning effect B at the time of winning the replay 1 permitted by the replay A or the bell winning permitted by the bell. By performing C, it is suggested that there is a high possibility that the low-speed stop control has been won. In particular, the winning effect C is determined so that it can be selected only when the low speed stop control is performed, and the winning effect C is given at the time of winning the replay 1 permitted by the replay A or at the bell winning permitted by the bell. By being performed, it is suggested that the low-speed stop control has been won.

  Also, in the winning effect selection lottery, the percentage that the low-speed stop control is won and the low-speed stop control is not performed at the time of replay A winning or the bell winning in which the low-speed stop control may be performed is a predetermined ratio. In the following cases, the selection rate of the winning effects A to C when the normal stop control is applied does not change as compared with the case where the predetermined ratio is exceeded, whereas the low speed stop control is applied. Among the winning effects A to C, the ratio of winning effects B and C is determined to be high, and the ratio of winning the low speed stop control and not performing the low speed stop control is equal to or less than a predetermined ratio. In such a case, compared to a case where the predetermined ratio is exceeded, an input suggesting that the low-speed stop control may have been won at the time of winning the replay 1 permitted by the replay A or at the time of the bell winning permitted by the bell. Director B, C is easily done.

  As described above, in the slot machine 1 of the present embodiment, regardless of whether or not the low speed stop control is performed during the replay A winning or the bell winning where the low speed stop control may be performed. In the case where any one of the winning effects A to C is selected with a probability according to whether or not the low speed stop control is won, and the low speed stop control is won, the low speed stop control is not won. In comparison with the case, it is determined that the ratio of the winning effects B and C to be selected among the winning effects A to C is high, and is permitted at the time of winning the replay 1 permitted by the replay A or by the bell. When the winning effects B and C are performed at the time of the bell winning, it is suggested that there is a high possibility that the low-speed stop control has been won. For this reason, if you missed whether or not the low-speed stop control was performed at the time of winning the Replay 1 or at the time of the bell winning, or even if the low-speed stop control was won, the number of sliding frames per frame was not selected, so the low-speed stop Even if the control is not performed, it is possible to infer whether or not the low speed stop control has been won from the difference in the aspect of the winning effect, so the interest by providing the low speed stop control is effective. Can be increased.

  Further, in this embodiment, the winning effect C among the winning effects B and C is determined so that it can be selected only when the low speed stop control is won. Since the winning effect C is performed at the time of the bell winning allowed by the bell, it is suggested that the low-speed stop control is won. Therefore, the low-speed stop control is performed at the time of winning the replay 1 or at the bell winning. The winning effect C is executed even if it is overlooked whether or not it has been performed, or even if the low speed stop control is won and the low speed stop control is not performed because the number of sliding frames of one frame is not selected. As a result, it is possible to recognize that the low-speed stop control has been won.

  In this embodiment, when the low-speed stop control is won and the ratio at which the low-speed stop control is not performed is equal to or less than a predetermined ratio, it is allowed by the replay A as compared with the case where the predetermined ratio is exceeded. Winning effects B and C suggesting the possibility of winning the low-speed stop control at the time of replay 1 winning or at the time of the bell winning allowed by the bell are easy to be performed, and the game where the low-speed stop control was won in the past When the low-speed stop control falls below a certain ratio, the accuracy of determining whether or not the low-speed stop control due to the winning effects B and C has been won increases, so the low-speed stop control is difficult to perform. Therefore, the player who is performing the stop operation can be made to recognize the possibility of having won the stop control.

  In this embodiment, the low-speed stop control is performed on the condition that the number of sliding symbols is 1 when the Replay A or the bell that won't be missed regardless of the timing of the stop operation is selected. However, as in Example 2, which will be described later, in the configuration in which the low speed stop control is performed on the condition that the stop operation is performed within the drawing range of these configuration symbols at the time of winning of the watermelon A, watermelon B, etc. where the overshoot occurs. The rate at which the low speed stop control is performed varies greatly depending on the skill of the player. However, as in this embodiment, the low speed stop control has fallen below a certain rate in the game where the low speed stop control has been won in the past. In such a case, the accuracy of determining whether or not the low-speed stop control is won due to the winning effects B and C being increased can be adjusted according to the skill of the player. Winning director B at the exact probability, C is carried out. That is, to a low-skilled player, that is, a player who has a low probability of performing low-speed stop control because the combination of watermelon A and watermelon B cannot be prepared even if the watermelon A or watermelon B is won. On the other hand, whether or not the low-speed stop control is won can be grasped from the prize-winning effect by increasing the accuracy of determining whether or not the low-speed stop control due to the winning effects B and C being won.

  Also, in this embodiment, among the replays A and bells that can be controlled at a low speed stop, the replay A having a low value given by the winning of the winning combination (eight at the time of winning the bell allowed by the bell) Is awarded when the Replay 1 allowed by Replay A is a replay game equivalent to three medals). Since the ratio of selection of winning effects B and C at the time of winning the low speed stop control is set higher than sometimes, the value given compared to the bell is low, and the player may not pay attention In a high situation, it becomes easier to guess whether or not the low speed stop control has been won depending on the type of winning effect.

  In the present embodiment, the winning effect using the reel LED 55 is applied as the post-derivation effect, but this is executed when the stop state can be stopped at least in the internal lottery result in which the low speed stop control can be performed. An effect may be used, and an effect produced by an image or video displayed on the liquid crystal display 51, an effect produced by sound, or an effect produced by combining these effects may be applied.

  Also, in this embodiment, the low-speed stop control was won in the game regardless of whether the low-speed stop control was performed at the time of replay A winning or the bell winning where the low-speed stop control might be performed. Either of the winning effects A to C is selected with a probability depending on whether or not, but the low speed stop control at the time of replay A winning or the winning of the bell where the low speed stop control may be performed Regardless of whether a low-speed stop control is won or not in the game, the probability of the low-speed stop control may be performed at the time of Replay A winning or the bell winning A stop lottery that determines whether or not to perform a stop stage presentation that can be executed after reeling is performed, and when the stop stage lottery is won, a stop stage presentation is performed. If the low-speed stop control is not won, it is determined that the execution probability of the stop-time effect is higher, so that the replay 1 allowed by the replay A or the bell It may be a configuration that suggests that there is a high possibility that the low-speed stop control has been won by performing an allowed stop-time effect at the time of winning the bell, and even in such a configuration, the replay 1 The low-speed stop control is not performed because it was overlooked whether the low-speed stop control was performed at the time of winning a prize or at the time of the bell winning, or even if the low-speed stop control was won, the number of sliding frames of one frame was not selected. In this case, it is possible to infer whether or not the low-speed stop control has been won depending on whether or not the stop-time effect is executed, so that the interest by providing the low-speed stop control is effectively enhanced. Door can be.

  Further, in the configuration in which it is suggested that there is a high possibility that the low-speed stop control has been won by performing the stop-time effect as described above, the low-speed stop control is won and the low-speed stop control is performed. If the percentage that was not present is less than or equal to the predetermined percentage, the low-speed stop control is won at the time of winning the replay 1 permitted by the replay A or at the time of the bell winning permitted by the bell, as compared to the case where the predetermined percentage is exceeded. It is preferable that the stop-time effect that suggests that there is a high possibility that the player has been playing is executed at a high rate. If it falls below, the accuracy of determining whether or not the low-speed stop control was won because the stop effect was performed increases, so stop operation is performed at a timing when low-speed stop control is difficult to perform. That even the player, it is possible to recognize accurately it may have been elected to the stop control.

  In this embodiment, the low-speed stop control is performed on the condition that the number of sliding symbols is 1 when the Replay A or the bell that won't be missed regardless of the timing of the stop operation is selected. However, as in Example 2, which will be described later, in the configuration in which the low speed stop control is performed on the condition that the stop operation is performed within the drawing range of these configuration symbols at the time of winning of the watermelon A, watermelon B, etc. where the overshoot occurs. The rate at which the low speed stop control is performed varies greatly depending on the skill of the player, but as described above, when the low speed stop control falls below a certain rate in a game in which the low speed stop control has been won in the past, Is configured to increase the accuracy of determining whether or not the low-speed stop control has been won due to the effect at the time of stoppage. When stopped at a rate production is carried out. That is, to a low-skilled player, that is, a player who has a low probability of performing low-speed stop control because the combination of watermelon A and watermelon B cannot be prepared even if the watermelon A or watermelon B is won. On the other hand, whether or not the low-speed stop control is won can be grasped from the stop-time effect by increasing the accuracy of determining whether or not the low-speed stop control is won due to the stop-time effect.

  In addition, in the configuration in which it is suggested that there is a high possibility that the low-speed stop control is won by performing the stop-time effect as described above, among the replay A and the bell that can perform the low-speed stop control, Replay A of low value given by winning an allowed combination (8 medals are awarded when a bell is allowed by a bell, whereas Replay 1 is allowed by a replay A (Replay game equivalent to 3 medals is sometimes given) is more likely to be performed at the time of low speed stop control than at the time of winning the bell In such a situation, the value given compared to the bell is low, and in the situation where the player is not likely to pay attention, the presence or absence of the stop effect is determined. Yo Whether the slow stop control had been elected Te becomes more easily guessed.

  Further, in the above description, when the low speed stop control is won, the replay A is allowed by the replay A by determining that the execution probability of the stop effect is higher than when the low speed stop control is not won. Although the replay 1 is won and the stop effect at the time of the bell winning allowed by the bell is performed, the configuration suggesting that there is a high possibility that the low-speed stop control has been won is exemplified. Replay 1 winnings allowed by Replay A by determining that the execution probability of the stop effect is lower when the low speed stop control is won than when the low speed stop control is not won It may be configured that it is suggested that there is a high possibility that the low-speed stop control has been won by not performing the stop effect at the time of the bell winning allowed by the time or the bell.

  In this embodiment, the sub-control unit 91 performs an effect that suggests the possibility of winning the special role over a plurality of games, triggered by the winning of the general role that can be expected to win the special role, and finally wins the special role. A continuous effect that leads to an effect result indicating whether or not there is is executed. In addition, the sub-control unit 91 executes a precursor effect that suggests that a continuous effect is executed over a plurality of games when a continuous effect is executed for some of the general roles that can be expected to win the special role. .

  FIG. 50 is a diagram showing a flow of execution of a continuous effect and a precursor effect.

  First, if you win a watermelon A, watermelon B, cherry A, or cherry B that you can expect to win special roles in the normal gaming state, you will perform a continuous production lottery that determines whether or not to perform a continuous production. By winning the continuous effect, the continuous effect is executed from the next game, and it is notified whether the special role is won or not.

  On the other hand, when replay B1, replay B2 or replay C that can be expected to win a special role in the normal gaming state is won, a prelude effect lottery is performed to determine the number of predecessor games.

  Predictive effects are executed over the number of games won in the prelude production lottery, and the continuous production lottery is performed at the end of the prelude production, and the continuous production is executed following the prelude production by winning the continuous production in the continuous production lottery. Whether or not the special role is won is notified.

  As described above, when the continuous effect is executed, there are a case where the continuous effect is executed without the precursor effect and a case where the continuous effect is executed after the precursor effect.

  In this embodiment, the sign production and the continuous production are determined by individual lottery, and the continuous production can be determined according to the state of the sign production. The structure which determines a continuous effect collectively may be sufficient, and it can determine a precursor effect and a continuous effect as a more relevant effect by setting it as such a structure.

  The sign effect is an effect suggesting the possibility that the continuous effect is executed by continuously executing the chance effect indicating the possibility of winning the special role over the period of the sign effect.

  In the chance effect, as shown in FIG. 51 (a), “?” Is displayed on the liquid crystal display 51 simultaneously with the start of the game accompanying the operation of the start switch 7, as shown in FIGS. 51 (b) and 51 (c). In addition, by displaying an item indicating the possibility of winning the special role at the timing when the reel stops, this is an effect suggesting the possibility of winning the special role.

  Items indicating the possibility of winning the special role include a “normal pattern” shown in FIG. 51B and a “sakura pattern” shown in FIG. 51B.

  The sub-control unit 91 performs a chance effect execution lottery to determine whether or not to execute a chance effect in the normal gaming state, and executes the chance effect of the selected type by winning. In the chance production lottery, as shown in FIG. 52, the chance production is won with a higher probability when the special role is won than in the case where the special role is not won, in a state other than the sign production (normal time in the figure). In addition, among the “normal pattern” and “cherry blossom pattern” items that indicate the possibility of winning the special role at a higher ratio when the special role is won than when the special role is not won. It is determined that the chance effect that the item of “sakura pattern” is displayed will be won.

  For this reason, in the state other than the sign production, the chance production is executed, which suggests that there is a high possibility that the special role has been won. When a chance effect is displayed in which a “sakura pattern” item is displayed among “normal pattern” and “sakura pattern” as an item to be displayed, a chance effect is displayed in which a “normal pattern” item is displayed It is suggested that the possibility of winning special roles is higher than the case.

  In the chance effect execution lottery, it is determined that the chance effect is won with a probability of 100% during the sign effect, and the chance effect is executed every game during the sign effect period. At this time, as in the case where the special role is elected, the item “normal pattern” and “sakura pattern” is selected as an item indicating the possibility of winning the special role at a higher ratio when the special role is elected than when the special role is won. Since it is determined that the chance effect that the item of “Sakura pattern” is displayed will be won, the item of “Sakura pattern” of “Normal pattern” and “Sakura pattern” is shown as an item indicating the possibility of winning the special role When a chance effect is displayed, a special role is more likely to be won than when a chance effect with a “normal pattern” item is displayed. Yes.

  When the replay B1, the replay B2, and the replay C are won in the normal gaming state, the sub-control unit 91 performs a sign effect lottery that determines the number of sign effects. In the sign production lottery, as shown in FIG. 53, whether Replay B1 is won alone, Replay B1 + special role is won, Replay B2 is won alone, Replay B2 + special role is won Whether the replay C is won alone or the replay C + special role is won is determined from the number of games of 2, 3, or 4 with the probability depending on whether the game is a replay C + special role. .

  Specifically, the winning rate when Replay B1 is selected alone is 20% for 2 games, 60% for 3 games, and 20% for 4 games. 3 games.

  The winning rate at the time of winning Replay B1 + special role is 10% for 2 games, 40% for 3 games, and 50% for 4 games, and the average number of prelude effects executed when winning Replay B1 + special role is 3 .4 games.

  The winning rate when Replay B2 is selected alone is 50% for 2 games, 40% for 3 games, and 10% for 4 games. It is a game.

  The winning rate at the time of winning Replay B2 + special role is 20% for 2 games, 40% for 3 games, and 40% for 4 games. .2 games.

  The winning rate when Replay C is alone won is 10% for 2 games, 40% for 3 games, and 50% for 4 games, and the average number of predictive effects executed when Replay C is alone won is 3.4. It is a game.

  The winning rate at the time of winning Replay C + Special Role is 10% for 2 games, 40% for 3 Games, and 50% for 4 Games, and the average number of games of the prelude effect executed when Winning Replay C + Special Role is 3 .4 games.

  In this way, in the sign production lottery, a larger number of games are more likely to be selected as the number of games of the sign production when the replay B1 and replay B2 are won at the same time as the special role than when the replay B1 is won alone. The number of games increases. For this reason, it is suggested that the more the number of games of the prelude effect executed after winning the replay 2 permitted by the winning of the replay B1 and the replay B2, the higher the possibility of winning the special role. .

  In addition, among Replay B1 and Replay B2, the number of games with a high simultaneous expectation degree, that is, Replay B1, which can be expected to win a special role, is more likely to be selected as the number of games of precursor effect, and the average number of games increases. For this reason, the possibility of winning a special role suggested by the number of games of a prelude effect executed after winning Replay 2 allowed by winning Replay B1 and Replay B2, and the symbols arranged at the time of winning Replay B1 and Replay B2 The possibility of winning a special combination suggested by the type of winning combination suggested by the combination is easily matched.

  As for Replay C, it will be won almost simultaneously with the special role, and even if the special role is not won, the advantageous RT will be decided. Regardless of whether there is a winning combination with a special role or not, it is easy to select a large number of games as the number of games for the prelude effect.

  As shown in FIG. 54, the continuous production consists of six types of production patterns 1 to 6, and each of the production patterns 1 to 6 includes a production pattern of “−1” indicating the non-winning special role, and a special role. The production pattern of “−2” indicating the winning of is determined.

  In the effect pattern 1-1, after the effect start screen (normal) shown in FIG. 55 (a) is displayed in the first game, the normal pattern is shown in the second game as shown in FIGS. 55 (c) and (d). Fireworks production production (normal) for producing fireworks is performed, and in the third game, as shown in FIGS. 56 (f), (g), and (i), a fireworks launch production that fires fireworks without a cut-in production ( (No cut-in) is executed, and finally, as shown in FIG. 56 (k), the launch failure effect is executed to notify the non-winning special role. The production pattern 1-2 is the same as the production pattern 1-1 except for the production result, but it is not a launch failure production as a final result, and a special launch execution production is performed as shown in FIG. 56 (j). This is a pattern for informing the winning of a role.

  In the effect pattern 2-1, after the effect start screen (sakura pattern) shown in FIG. 55 (b) is displayed in the first game, as shown in FIGS. Fireworks production production (normal) that produces fireworks with a pattern is performed, and in the third game, as shown in FIGS. 56 (f), (g), and (i), a fireworks launch production that fires fireworks without a cut-in production. (No cut-in) is executed, and finally, as shown in FIG. 56 (k), the launch failure effect is executed to notify the non-winning special role. The production pattern 2-2 is the same as the production pattern 2-1 except for the production result, but the final result is not a launch failure production, but a special launch execution production is performed as shown in FIG. 56 (j). This is a pattern for informing the winning of a role.

  In the effect pattern 3-1, the effect start screen (normal) shown in FIG. 55 (a) is displayed in the first game, and then the cherry pattern is shown in the second game as shown in FIGS. 55 (c) and (e). Fireworks production effect (cherry blossom pattern) to produce fireworks is performed, and fireworks launch effect in which fireworks are launched without a cut-in effect, as shown in FIGS. 56 (f) (g) (i), in the third game (No cut-in) is executed, and finally, as shown in FIG. 56 (k), the launch failure effect is executed to notify the non-winning special role. The effect pattern 3-2 is the same as the effect pattern 3-1, except for the effect result. However, as shown in FIG. This is a pattern for informing the winning of a role.

  In the effect pattern 4-1, after the effect start screen (normal) shown in FIG. 55 (a) is displayed in the first game, the normal pattern is shown in the second game as shown in FIGS. 55 (c) and (d). Fireworks production effect (normal) for producing fireworks is performed, and fireworks with a cut-in effect that interrupts an image on the display screen as shown in FIGS. 56 (f) (h) (i) in the third game Is a pattern in which a firework launch + cut-in effect is executed, and finally, the launch failure effect is executed to notify that the special role is not won, as shown in FIG. 56 (k). The effect pattern 4-2 is the same as the effect pattern 4-1 except for the effect result, but the final result is not a launch failure effect, but a special successful launch effect as shown in FIG. 56 (j). This is a pattern for informing the winning of a role.

  In the effect pattern 5-1, the effect start screen (sakura pattern) shown in FIG. 55 (b) is displayed in the first game, and then in the second game, as shown in FIGS. 55 (c) and (d). A fireworks production effect (usually) is created to produce a pattern firework, and a cut-in effect that interrupts the image on the display screen as shown in FIGS. 56 (f), (h), and (i) is performed in the third game. In this pattern, the fireworks launch + cut-in effect for launching the fireworks is executed, and finally, as shown in FIG. 56 (k), the launch failure effect is executed to notify the non-winning special role. The effect pattern 5-2 is the same as the effect pattern 4-1, except for the effect result. However, as shown in FIG. This is a pattern for informing the winning of a role.

  The effect pattern 6-1 displays the effect start screen (normal) shown in FIG. 55 (a) in the first game, and then displays the cherry pattern in the second game as shown in FIGS. 55 (c) and (e). A fireworks production effect (cherry blossom pattern) is produced to produce a firework, and a cut-in effect that interrupts the image on the display screen is shown in the third game as shown in FIGS. 56 (f) (h) (i). In this pattern, the fireworks launch + cut-in effect for launching the fireworks is executed, and finally, as shown in FIG. 56 (k), the launch failure effect is executed to notify the non-winning special role. The effect pattern 6-2 is the same as the effect pattern 4-1, except for the effect result. However, as shown in FIG. This is a pattern for informing the winning of a role.

  In the continuous effect lottery, as shown in FIGS. 57 (a) to (c), when there is a probability according to the presence or absence of the warning effect and the warning effect, the chance effect that the cherry pattern item is displayed during the warning effect. Whether or not to execute a continuous effect with a probability corresponding to whether or not is executed and one of effect patterns 1 to 6 is determined when executing a continuous effect.

  Specifically, in the case of continuous production lottery that is performed without winning indication, that is, when watermelon A, watermelon B, cherry A, and cherry B are selected, 70% of the non-winning (none) pattern is given when watermelon A is selected alone. 1 is 26%, Pattern 2 is 1%, Pattern 3 is 1%, Pattern 4 is 1%, Pattern 5 is 0.5%, and Pattern 6 is 0.5%. Winner (None) 50%, Pattern 1 16%, Pattern 2 8%, Pattern 3 8%, Pattern 4 9%, Pattern 5 5%, Pattern 6 5% At the time of winning, non-winning (none) is 40%, pattern 1 is 52%, pattern 2 is 2%, pattern 3 is 2%, pattern 4 is 2%, pattern 5 is 1%, pattern 6 is 1%, When winning the watermelon B + special role Non-winning (None) 20%, Pattern 1 15%, Pattern 2 15%, Pattern 3 15%, Pattern 4 15%, Pattern 5 10%, Pattern 6 10%, Cherry A In the single winning of 70%, non-winning (none) is 70%, pattern 1 is 26%, pattern 2 is 1%, pattern 3 is 1%, pattern 4 is 1%, pattern 5 is 0.5%, pattern 6 is 0 .5%, 50% for non-winning (none) at the time of winning the Cherry A + special role, 16% for pattern 1, 8% for pattern 2, 8% for pattern 3, 9% for pattern 4, and 5 for pattern 5 5%, Pattern 6 is 5%, Cherry B + special role is not elected (None) is 0%, Pattern 1 is 10%, Pattern 2 is 20%, Pattern 3 is 20%, Pattern 4 is 20 %, Pattern 5 is 20%, Pattern Down 6 is 20%.

  In the case where the sign effect is accompanied, that is, when the replay B1, the replay B2 and the replay C are won, the chance effect that the cherry blossom pattern is displayed as an item during the sign effect is not executed. When Replay B1 is selected alone, non-winning (none) is 50%, pattern 1 is 50%, pattern 2 is 0%, pattern 3 is 0%, pattern 4 is 0%, pattern 5 is 0%, and pattern 6 is 0%, 40% for non-winning (none) at the time of replay B1 + special role, 40% for pattern 1, 5% for pattern 2, 5% for pattern 3, 5% for pattern 4, 5 for pattern 5 %, Pattern 6 is 2%, and when Replay B2 is selected, 60% is not selected (None), Pattern 1 is 40%, Pattern 2 is 0%, Pattern 3 is 0%, Pattern 4 is 0 , Pattern 5 is 0%, pattern 6 is 0%, replay B2 + special role is elected, 50% is not elected (none), pattern 1 is 34%, pattern 2 is 4%, pattern 3 is 4%, Pattern 4 is 4%, Pattern 5 is 2%, and Pattern 6 is 2%. When Replay C is selected alone, non-winning (none) is 0%, Pattern 1 is 80%, Pattern 2 is 5%, Pattern 3 Is 5%, pattern 4 is 5%, pattern 5 is 3%, pattern 6 is 2%, non-winning (none) is 0%, pattern 1 is 80%, and pattern 2 5%, pattern 3 is 5%, pattern 4 is 5%, pattern 5 is 3%, and pattern 6 is 2%.

  In the case where a prelude effect is accompanied, that is, a continuous effect lottery executed at the time of winning Replay B1, Replay B2, and Replay C, and a chance effect that a cherry pattern is displayed as an item during the predecessor effect is executed. 50% non-winning (none) at replay B1 single win, pattern 1 50%, pattern 2 0%, pattern 3 0%, pattern 4 0%, pattern 5 0%, pattern 6 0 When Replay B1 + special role is elected, 40% is not elected (None), Pattern 1 is 60%, Pattern 2 is 0%, Pattern 3 is 0%, Pattern 4 is 0%, Pattern 5 is 0% Pattern 6 is 0%, and when Replay B2 is selected alone, 60% is not selected (None), Pattern 1 is 40%, Pattern 2 is 0%, Pattern 3 is 0%, Pattern 4 is 0%, 5% is 0%, pattern 6 is 0%, replay B2 + special role is elected 50% non-winning, pattern 1 50%, pattern 2 0%, pattern 3 0%, Pattern 4 is 0%, Pattern 5 is 0%, and Pattern 6 is 0%. When Replay C is selected alone, non-winning (none) is 0%, Pattern 1 is 100%, Pattern 2 is 0%, Pattern 3 Is 0%, Pattern 4 is 0%, Pattern 5 is 0%, and Pattern 6 is 0%. When Replay C + Special Role is selected, non-winning (none) is 0%, pattern 1 is 100%, and pattern 2 is 0%, pattern 3 is 0%, pattern 4 is 0%, pattern 5 is 0%, and pattern 6 is 0%.

  As described above, in this embodiment, in the continuous production lottery, regardless of whether or not the sign production is accompanied, the ratio of winning the continuous production higher when the special role is won than when the special role is not won. It is suggested that the possibility that the special role is won is high by executing the continuous performance.

  In addition, when there is no sign effect, or when the chance effect that the sign pattern is displayed but the cherry pattern is displayed as the item during the sign effect is not executed, the effect start effect (cherry blossom) Patterns 2 and 5 or fireworks production effects (cherry blossom) production patterns 3 and 6 are more likely to be won when the special role is won than when the special role is not won In the case of a cherry blossom pattern in a fireworks production effect or a fireworks production effect, the possibility of winning a special role is higher than in the case of a normal pattern.

  Also, when there is no sign effect, or when there is no chance effect that the cherry pattern is displayed as an item during the sign effect but with the sign effect, among the effect patterns 1 to 6, fireworks rise + cut-in The ratio of the production patterns 4 to 6 to be won is higher when the special role is won than when the special role is not won. It is more likely that you have won a special role than if you were not accompanied.

  Also, when there is no sign production, compared to the case with the sign production, the production pattern or fireworks launch production that will be a cherry pattern that can be expected to win a special role than the normal pattern in the firework production production or fireworks production production The ratio of production patterns with cut-in that can be expected to win special roles is higher than the case without cut-in in, and in continuous production without sign production, compared to continuous production with sign production, Fireworks production production or fireworks production production that becomes a cherry blossom pattern that can be expected to win special roles over normal patterns is easier to perform, and fireworks launch production with cut-in that can be expected to win special roles than without cut-in Is easier to execute.

  On the other hand, when a chance effect is displayed during which the cherry blossom pattern that can be expected to win a special role is displayed as an item during the sign production, it is normal in the fireworks production production or fireworks production production in the continuous production following the sign production. The production pattern with the cherry blossom pattern that can be expected to win the special role rather than the pattern and the production pattern with the cut-in that can be expected to win the special role are not won than the case without the cut-in in the fireworks launch production In such a case, there will be no fireworks production production or fireworks production production that will be a cherry blossom pattern that can be expected to win a special role over the normal pattern, and it will be more special than the case without cut-in There will be no fireworks display with cut-in that you can expect to win.

  Further, in this embodiment, during the continuous production of production pattern 1, that is, the fireworks production production or the fireworks production production without the cherry blossom pattern and the continuous production without the cut-in in the fireworks display production, the special role can be won simultaneously. If the general role is won, the fireworks production production (normal) will be the second game if it is won, and the fireworks production production (sakura pattern) can be expected to win the special role more than that. There will be a chance-up effect that replaces “no cut-in” with fireworks launch and cut-in production that can be expected to win a special role.

  Whether or not to perform a chance-up effect is determined by a chance-up lottery executed by the sub-control unit 91 when a general combination that can be won simultaneously with the special combination is won during the continuous production of the production pattern 1.

  As shown in FIG. 58 (a), the winning rate of the chance-up lottery is 5% in the case of non-special role winning at the time of winning the watermelon A if it is in the continuous production based on the production pattern 1 without the sign production. 15% if special role is elected, 10% if special feature is not elected when watermelon B is elected, 30% if elected special role, 5% if special role is not elected when Cherry A is elected 15% in the case of winning, 50% in the case of special winning in the Cherry B winning (special role confirmed), 0% in the case of non-special winning in the replay B1 winning, 5% in the case of special winning When replay B2 is won, it is 0% when the special role is not won, 5% when the special role is won, 5% when the special role is not won when replay C is won, and 5% when the special role is won.

  In addition, as shown in FIG. 58 (b), in the case of a continuous production based on the production pattern 1 accompanied by the sign production, and the chance production in which the cherry blossom pattern is displayed as the item during the production of the sign production is not executed, 1% if the special role is not selected when the watermelon A is won, 3% if the special role is won, 2% if the special role is not selected when the watermelon B is won, 6% if the special role is won, Cherry A 1% if the special role is not elected at the time of winning, 3% if the special role is elected, 10% if the special role is elected when Cherry B is elected (special role is confirmed), and when the replay B1 is elected (special role is confirmed) 1% in the case of special role winning, 0% in the case of non-special winning in Replay B2, 1% in the case of special winning, and in the case of special winning in replay C winning (special role confirmed) 5%.

  In addition, as shown in FIG. 58 (c), when the stage effect is being performed based on the effect pattern 1 with the sign effect, and the chance effect in which the cherry blossom pattern is displayed as the item during the sign effect is performed, the watermelon 0% if the special role is not selected at the time of winning A, 0% if the special role is won, 0% if the special role is not selected when winning the watermelon B, 0% if the special role is won, Cherry A won 0% if no special role is won, 0% if a special role is won, 0% if a special role is won when Cherry B is won (special role is confirmed), if a replay B1 is selected (special role is confirmed) 0% for special role winning, 0% for non-special winning in replay B2 win, 0% for special winning, 0 for special winning in replay C winning (special role confirmed) %.

  In this way, in the chance-up lottery, it is being continuously produced based on the production pattern 1 with the sign production, and it is further won for the special role except when the chance production in which the cherry blossom pattern is displayed as the item is executed during the sign production. The ratio of winning the chance-up lottery is higher than the case where the special role is not won when the special role is won, except for Replay C where the advantageous RT is fixed even if it is not, When a general role that can be elected at the same time as a special role is elected, it was suggested by the election of a general role that can be elected at the same time as a special role by performing fireworks production production (sakura pattern) and fireworks launch + cut-in production The possibility of winning a special role will be further increased.

  In addition, during the continuous production with the sign production, even if the general role that can be elected simultaneously with the special role is won, the chance of winning the chance up lottery is low compared to the case without the sign production, It has become difficult to execute. In particular, if a chance effect with a cherry blossom pattern displayed as an item during the sign effect is executed, the chance up effect will not be executed. In such a case, the chance up effect will not be executed. Yes.

  As described above, in the slot machine 1 according to the present embodiment, when performing a continuous performance that suggests the possibility of winning a special role, the continuous performance is performed through a precursor effect that suggests the possibility of winning a special role. Is executed, and there is a case where a continuous effect is executed without a precursor effect.

  For this reason, when a continuous production is performed without a warning effect, the expectation of winning the special role can be sufficiently increased as compared with a case where a continuous performance is executed after the warning effect. It becomes difficult.

  On the other hand, in this example, when there is no sign production, compared to the case with the sign production, the cherry blossom pattern that can be expected to win a special role than the normal pattern in the fireworks production production or fireworks production production. The production pattern with cut-in that can be expected to win a special role is higher than the case without cut-in in the production pattern and the fireworks launch production, and the continuous production without the sign production is accompanied by the sign production Compared to continuous production, fireworks production production or fireworks production production that becomes a cherry blossom pattern that can be expected to win special roles over normal patterns is easier to be executed, and special characters can be expected to win than when there is no cut-in Fireworks launch effects with cut-in are easier to execute.

  For this reason, in the continuous performance that was executed through the warning effect, the expectation for the winning of the special role suggested by the continuous performance can be enhanced by the warning effect, while in the continuous performance that was executed without the warning effect. , The cherry blossom pattern and the production pattern with cut-in suggesting that the possibility of winning the special role is high at a high rate compared to the case where the sign production was passed, so the continuous execution was carried out without the sign production Even if it is a production, the expectation that the special role is elected can be sufficiently enhanced.

  Also, in this embodiment, it is determined whether to execute a continuous effect without a precursor effect or to execute a continuous effect after a precursor effect according to the type of general role won in the internal lottery. It has become. That is, among the general roles that can be expected to win the special role, when the watermelon A, watermelon B, cherry A, and cherry B are selected, the continuous performance is executed without the warning effect, and when the replay B1, replay B2, and replay C are selected. The continuous production is executed after the sign production.

  In particular, in this embodiment, replay B1, replay B2, and replay C that shift to the RT or advantageous RT by winning even if the special role is not won, that is, the replaying role that cannot be won to win the special role. As the winning probability increases, it becomes difficult to determine whether the special role is won or not until it is informed whether the special role is won or not based on the result of the continuous production. At the time of winning, a continuous production with a prelude effect is executed, so even if the expectation for the special role winning is long-termed by both the prelude production and the continuous production, the expectation for the special role winning to the end Watermelon A, Watermelon B, Cherry A, Cherry B, Suna that can be sustained, but will not shift to production RT, etc. if they are not selected for special roles In the case of a general role winning that can determine whether or not a special role has been won to some extent by a player's stoppage aiming at the special role and the player performing a stop operation aiming at the special role, a continuous performance will be performed without a warning effect In this way, it is possible to prevent the sign production and the continuous production from continuing for a long period of time, although it is clear that the special role has not been won.

  Also, in this embodiment, when a chance effect is displayed during which the cherry blossom pattern that can be expected to win a special role is displayed as an item during the sign effect, a fireworks production effect or a firework is displayed in the continuous effect following the sign effect. The production pattern with a cherry blossom pattern that can be expected to win a special role over a normal pattern in production production and the production pattern with a cut-in that can be expected to win a special role than without a cut-in in a fireworks launch production will not win In such cases, there will be no fireworks production or fireworks production production that will be a cherry blossom pattern that can be expected to win special roles over normal patterns, and there is no cut-in. However, there will be no fireworks launch with cut-in that can be expected to win special roles. For this reason, the sign production with the cherry blossom pattern and the production pattern with the cherry blossom pattern and cut-in are executed excessively. It can prevent the expectation for winning from fading.

  Also, in this embodiment, when a general role that can be simultaneously elected with a special role is won during the continuous performance, if the second game, the firework production effect (normal) can be expected to win the special role more than that. In the production production (sakura pattern), if it is the third game, a fireworks launch production (no cut-in) will be given, and a chance-up production will be provided to replace the fireworks launch + cut-in production that can be expected to win a special role. That is, in the situation where the winning of the general role that suggests the winning of the special role is permitted, the production pattern with the cherry blossom pattern and the cut-in is executed, so that the player's expectation can be effectively enhanced.

  In addition, the chance-up production is performed at a higher rate in the continuous production without the warning effect than the continuous production with the warning effect. It is possible to effectively increase the expectation for winning.

  On the other hand, even when a general role that can be elected simultaneously with a special role during a continuous performance is won, it has already been decided that a performance pattern with cherry blossom pattern or cut-in will be executed during the same continuous performance. If a chance effect with a cherry blossom pattern is being performed during the sign production, the chance up production is not performed, and excessively, the sign production with the cherry blossom pattern, the cherry pattern or cut Execution of the effect pattern accompanied with in can prevent the expectation for winning the special role by the effect of the sign with cherry blossom pattern or the pattern with cherry pattern or cut-in.

  In this embodiment, as a right that is advantageous to the player, a special role that accompanies a transition to a bonus, that is, a right that enables the player to make a transition to a gaming state that is advantageous to the player is applied. In addition, an effect that expects the winning of a special role is applied as a continuous effect as a specific effect. However, the present invention is not limited to this, and as a right advantageous to a player, a game state advantageous to a player other than a bonus, for example, normal Information that is advantageous to the player, such as an increase in the winning probability of the specific role and an operation mode for deriving a stop mode (a winning mode or a non-winning mode) that is advantageous to the player For example, it is possible to win an advantageous player with a transition to a gaming state that can be expected to acquire more gaming value than usual, and to control these advantageous gaming states. Applying the right that can be operated (winning the lottery to determine whether to control to the advantageous state) or the right to be notified of the operation mode for deriving a display result advantageous to the player In this case, it is only necessary to apply an effect suggesting the possibility that these rights are given as a precursor effect and a specific effect.

  Further, in this embodiment, a continuous effect that continues over a plurality of games is applied as the specific effect, but an effect that is completed within one game may be applied as the specific effect. Similarly, in this embodiment, the sign effect that continues over a plurality of games is applied as the sign effect, but an effect that ends within one game may be applied as the specific effect.

  In addition, in this embodiment, the chance effect continues during the sign effect as the sign effect, but the effect that is connected before and after such as the effect that the story progresses step by step for each game is applied as the sign effect. Also good.

  In addition, in this embodiment, a sign production or a continuous production is executed when a general role that can be expected to win a special role is elected, and the expectation accompanying the execution of the sign production or the continuous production is further enhanced. This is preferable, but it is not triggered by the fact that a general role that can be expected to win a special role is won, and a sign production or a continuous production is executed depending on the result of a lottery depending on whether or not a special role is won. But it ’s okay.

  As described above, the first embodiment of the present invention has been described with reference to the drawings. However, the present invention is not limited to the first embodiment, and the present invention can be modified or added without departing from the gist of the present invention. Needless to say, it is included.

  In the first embodiment, it is a configuration that suggests the possibility of winning the special role by performing the low speed stop control, but any configuration that suggests some information to the player by performing the low speed stop control may be used. A configuration that suggests the possibility that the right to shift to an advantageous gaming state is granted or the possibility that the lottery of whether or not to shift to an advantageous gaming state is preferentially given more than usual may be adopted. Furthermore, it may be configured to suggest that a setting value that is more advantageous to the player among a plurality of setting values is set for the player.

  In the first embodiment, as the special derivation control, the low speed stop control is applied to stop the reel at the target stop position more slowly than the normal stop control after detecting the stop operation. Any control may be used as long as it performs control for deriving the display result in a special stop mode. For example, control that stops the reel while vibrating it up and down (so-called bound stop) may be applied as the special derivation control. .

  In the embodiment, one frame is applied as the number of sliding frames suitable for special derivation control. However, the number of sliding frames suitable for special derivation control is not limited to this, and is more suitable for special derivation control. A plurality of sliding symbols may be used.

  In the embodiment, an example is described in which three reels 2L, 2C, and 2R are applied as variable display devices. However, only one reel is provided, and a winning is determined according to the display result of the one reel. Alternatively, two reels may be provided, and winning may be determined according to the combination of display results of the two reels, or four or more reels may be provided, and winning may be determined according to the combination of display results of these reels. May be determined.

  In the first embodiment, three reels 2L, 2C, and 2R are applied as variable display devices. When all the reels are stopped, one game is finished, and a prize is awarded according to a combination of display results derived to the three reels. Although a slot machine in which a game is generated is described, a game can be started by setting a predetermined number of bets for one game using the gaming value, and a plurality of types of identification that can be distinguished from each other Even in a slot machine in which one game is completed when a display result is derived to a variable display device capable of variably displaying information, and a winning can be generated according to the display result derived to the variable display device A variable display device capable of deriving a display result in each of a plurality of variable display areas capable of variably displaying a plurality of types of identification information each identifiable, The game can be started by setting a predetermined number of bets for one game using, and the display result is derived and displayed in all of the plurality of variable display areas. It may be a slot machine in which a winning can be generated according to a combination of the display results derived and displayed in each of the plurality of variable display areas as a result of one game.

  In the first embodiment, an example in which the present invention is applied to a slot machine in which bets are set using medals and credits as game values has been described. However, slots for setting bets using game balls as game values are described. 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.

  Next, a slot machine according to a second embodiment to which the present invention is applied will be described. Since the slot machine of the present embodiment has a configuration similar to that of the first embodiment, detailed description of the same configuration is omitted, and different points are mainly described here.

  In the first embodiment described above, the main control unit 41 is configured such that the low speed stop control can be executed when the replay A is won during RT1 or RT4, and when the bell is won during BB1 or BB2. Then, at the time of winning of watermelon A or watermelon B in the normal gaming state, RT1 to 4, low speed stop control can be executed when BB1 or BB2 is won and no general role is won. Yes.

  FIG. 59 is a flowchart showing the control content of the low-speed stop determination process performed by the main control unit 41 in this embodiment.

  In the low-speed stop determination process of the present embodiment, first, it is determined whether or not it is BB (Si1051). Next, if it is not in BB, it is determined whether or not watermelon A or watermelon B has been won (Si1052). If watermelon A or watermelon B has been won, the process proceeds to step Si1055.

  If neither watermelon A nor watermelon B is elected in the step of Si52, it is determined whether or not BB1 or BB2 is elected (Si1053). (Si 1054), and if no general combination is won, the process proceeds to Si 1055.

  In the step of Si1055, it is determined whether or not the special role confirmation notification has already been performed. If it is determined that the special role determination notification has not been performed, the low speed stop is performed with the probability shown in FIG. A low speed stop lottery for determining whether or not to perform control is performed (Si1056).

  Then, it is determined whether or not the low speed stop control is won (Si1057). When it is determined that the low speed stop control is won, a low speed stop control flag indicating the low speed stop control is set (Si1058).

  In addition, when BB is in the step of Si1051, when BB1 and BB2 are not won in the step of Si1053, when any of the general roles is elected in the step of Si1054, after confirming the special role in Si1055 If the low-speed stop control is not won in the step of S1057, the process is terminated at that time, and the low-speed stop control is not performed in the game.

  In the low speed stop decision process, when BB1 or BB2 is won at the time of winning of a watermelon A or watermelon B that can be expected to win a special role in the normal gaming state, RT1 to 4, and no role is won The low-speed stop lottery is performed on the condition that the special role confirmation notification is not performed, and the low-speed stop lottery is performed, so that the low-speed stop control can be performed in the game.

  In the low-speed stop lottery, as shown in FIG. 60, the probability of winning the low-speed stop control in the normal gaming state, when watermelon A or watermelon B in RT1 to 4 is selected alone (settings 1-3: 3.9%, setting 4) 5: 4.7%, setting 6: 5.5%) than the normal gaming state, the probability of winning the low-speed stop control at the time of simultaneous winning of watermelon A or watermelon B and special role in RT1-4 6: 19.5%) is set high. In addition, the probability of winning the low-speed stop control in the normal gaming state, when the watermelon A or watermelon B in the RT1 to 4 is selected alone is higher than the low setting range (settings 1 to 3) (settings 4 to 6). Is higher.

  In addition, when BB1 or BB2 is elected and neither general role is elected, there is a low probability (setting 1 to 6: 3.1%), but low speed stop control is won. It has become. In other words, when the special combination is won and no general combination is won, the low-speed stop control is performed, so that the most advantageous BB1 or BB2 of the BBs is confirmed.

  When the low-speed stop control flag is set in the low-speed stop determination process, the low-speed stop control is applied if one frame is selected as the number of sliding frames when the reel is stopped by a stop operation thereafter.

  In addition, when the low speed stop control flag is not set or when the low speed stop control flag is set, but 0, 2, 3, and 4 are selected as the number of sliding frames, the reel is stopped by the stop operation. In this case, the normal stop control is applied.

  As described above, since the low speed stop control flag is not set during the BB or after the special role is confirmed, the low speed control flag is not set even during the BB or after the special role is confirmed. Stop control is never performed.

  FIG. 61 is a flowchart showing the control contents of the stop switch process executed in the timer interrupt 4 of the timer interrupt process described above by the main control unit 41 of the present embodiment.

  In the stop switch process, first, for all reels in the order of left, middle, and right, it is determined whether or not a stop operation position has been set for the work on the corresponding reel, that is, whether a stop operation has been detected (Sk1101, Sk1102) If stop operation is not detected for all reels, the stop switch process is terminated and the process returns to the flowchart of FIG.

  If any reel stop operation is detected in step Sk1101, the process proceeds to step Sk1103.

  In the step of Sk1103, the virtual sliding frame table corresponding to the reel is referred to, and the region number serving as the stop position is identified from the region number including the step number of the stop operation position set for the work corresponding to the stop reel. .

  Next, it is determined whether or not the low speed stop control is won in the low speed stop lottery, that is, whether or not the low speed stop control flag indicating the low speed stop control is set (Sk1104). If it is determined in step Sk1104 that the low speed stop control has not been won, the stop switch process is terminated and the process returns to the flowchart of FIG.

  If it is determined in step Sk1104 that the low speed stop control has been won, it is determined whether or not watermelon A or watermelon B has been won (Sk1105), and watermelon A or watermelon B has been won. It is determined whether or not it is the third stop (Sk1106), and if it is the third stop, whether or not the combination of watermelon A or watermelon B is a balance, that is, the combination of watermelon A or watermelon B Are determined to be on the same winning line except for the reel (Sk1107). If the combination of watermelon A or watermelon B is a balance, the combination of watermelon A or watermelon B Whether or not the combination is a stop operation position on the winning line, that is, a combination of watermelon A or watermelon B It is determined whether or not it is a stop operation position where the remaining symbols of watermelon A or watermelon B can be drawn on the winning line where the balance is tempered (Sk1108), and the combination of watermelon A or watermelon B is the winning line. If the stop operation position is aligned upward, the process proceeds to step Sk1109.

  Note that if the stop is not the third stop in the step of Sk1106, the stop operation in which the combination of watermelon A or the combination of watermelon B is aligned in the step of Sk1108 if the combination of watermelon A or the combination of watermelon B is not completed in the step of Sk1107 If it is not the position, the stop switch process is terminated and the process returns to the flowchart of FIG.

  Further, when watermelon A or watermelon B has not been won in the step of Sk1105, that is, when BB1 or BB2 has been won and neither general role has been won, the reel to be stopped is the right reel. (Sk1111), if it is the right reel, it is determined whether the left reel has already been stopped and whether “cherry” is stopped on the winning line of the left reel (Sk1112). If the left reel has already been stopped and “Cherry” is stopped on the winning line of the left reel, whether or not the stop operation position is within the “Cherry” drawing range, that is, “Cherry” is displayed on the winning line. "Is a stop operation position that can be pulled in" (Sk1113). No.

  If the reel to be stopped in the step of Sk1111 is not the right reel, if the left reel is not stopped in the step of Sk1112 or if “cherry” is not stopped on the winning line of the left reel, in the step of Sk1113 If it is not within the “cherry” pull-in range, the stop switch process is terminated and the process returns to the flowchart of FIG.

  In the step of Sk1109, it is determined whether or not the number of steps specified in the step of Sk1103 is the number of steps (22 to 37) corresponding to one frame. If the number of steps does not correspond to one frame in the step of Sk1109, the stop switch process is terminated and the process returns to the flowchart of FIG.

  If the number of steps corresponds to one frame in the step of Sk1109, a low-speed stop execution flag for instructing execution of the low-speed stop control is set in the RAM 507 (Sk1110), the stop switch processing is ended, and the flow returns to the flowchart of FIG. To do.

  When the low speed stop execution flag is set in the stop switch process, the excitation time is controlled according to the low speed stop control in the subsequent stop process.

  Further, in the stop switch process, even when the low speed stop control flag is set, if the low speed stop control is already executed in the game, the low speed stop control is not instructed. Thus, when the low speed stop control is executed on any of the reels, the low speed stop control is not executed on the subsequent reels. Note that when low-speed stop control is executed, if the low-speed stop control flag is cleared and the low-speed stop control is executed for any reel, the low-speed stop control is not executed for the subsequent reels. It is good also as a structure to do.

  As described above, in this embodiment, when the watermelon A or the watermelon B is won, when the BB1 or BB2 is won and any general combination is not won, the low speed stop control is applied.

  And when watermelon A or watermelon B is won, if the low-speed stop lottery is won, the combination of watermelon A or watermelon B has been tempered by the second stop, and the combination of watermelon A being tempered or In order to align the combinations of watermelon B, it is necessary to perform a stop operation at the timing when the structural symbol is within the pull-in range, that is, the structural symbol is retracted at the time of the third stop, which may be missed if not pressed. The low-speed stop control is performed on the condition that the stop operation is performed at a timing within the range.

  On the other hand, if BB1 or BB2 is won and no general combination is won, the left reel has already stopped and “cherry” appears on the winning line of the left reel when the low speed stop lottery is won. In a situation where a reach can be established by stopping, it is necessary to perform a stop operation at a timing when “cherry” is within the pull-in range in order to determine whether or not the reach is established. The low speed stop control is performed on the condition that the stop operation is performed at the timing when the “cherry” is within the pull-in range in the right reel that needs to be pushed to determine whether or not

  Further, in this embodiment, the sub-control unit 91 has a timing of any one of game start, first stop, second stop, and third stop by operating the start switch 7 on condition that the watermelon A or watermelon B is won. A watermelon winning suggestion effect is executed to suggest that watermelon A or watermelon B has been won. At this time, the sub control unit 91 is higher when the watermelon A or the watermelon B is won in the main control unit 41 and is also won for the low speed stop control than when the low speed stop control is not won. The watermelon winning suggestion effect is executed with probability, and in this case, the ratio at which the watermelon winning suggestion effect is executed before the second stop at which the low speed stop control can be executed is high.

  As described above, in the slot machine 1 according to the present embodiment, the combination of the watermelon A or the combination of the watermelon B has reached the balance until the second stop, and the combination of the watermelon A or the combination of the watermelon B that is the balance is prepared. In order to achieve this, it is necessary to perform a stop operation at a timing when the structural symbol is within the pull-in range, that is, at the third stop, which may be missed if not pressed, or when the left reel has already stopped, In order to determine whether or not a reach eye can be established by stopping “Cherry” on the winning line, a stop operation is performed when “Cherry” is within the pull-in range. Low-speed stop control is performed on the right reel that needs to be performed, i.e., that must be pushed to determine the reach. You have me. That is, a specific display that does not stop if the stop operation is performed at a timing other than this timing by performing the stop operation at a timing that becomes the drawing range of the target symbol for the reel that is rotating before the stop operation is performed. When a specific event (the combination of watermelon A or watermelon B, the “cherry” stop on the left reel) stops suggesting that the result may be derived, that is, when the specific event does not occur In comparison, when attention is paid to reel fluctuations in order to perform a stop operation at a specific operation timing, low-speed stop control is performed, and it is effective for the player that the low-speed stop control is performed. Therefore, the interest by the low speed stop control can be effectively enhanced.

  In the present embodiment, the stop operation is performed at a timing that becomes the drawing range of the target symbol for the reel that is rotating before the stop operation is performed, and the operation is stopped when the stop operation is performed at a timing other than this timing. As specific events that suggest that a specific display result may be derived, a combination of watermelon A or watermelon B, a “cherry” stop on the left reel, that is, a stop of a stopped reel When the position is applied, but the number of sliding frames when the previous reel stops is a specific value (for example, 4 frames), the number of sliding frames when the previous reel stops is a specific value, When stopping at a stop position or when low-speed stop control is performed at the time of previous reel stop, the stop mode at the previous reel stop is a specific stop mode It may be applied as a specific event to become. Furthermore, execution of a specific effect may be applied as a specific event. In this case, it may occur even when all reels are rotating.

  Further, in this embodiment, when the stop operation is performed at a timing other than this timing by performing the stop operation at a timing that becomes the drawing range of the target symbol with respect to the rotating reel before the stop operation is performed, the reel is stopped. If a specific event has occurred that suggests that a specific display result may be derived, the stop operation is performed at a timing that is within the drawing range of the target symbol. When control is to be performed and the stop operation is performed at a timing other than the drawing range of the target symbol, that is, when the stop operation is performed at a timing at which a specific display result cannot be derived Since the low-speed stop control is not performed, the relationship between the specific stop control being performed and the specific display result being derived becomes clearer.

  In addition, the combination of watermelon A and watermelon B may be missed in all reels after the second stop, but when watermelon A or watermelon B is won, the third stop, that is, the combination of watermelon A or The combination of the watermelons B makes the low speed stop control in the situation where the winning of the watermelon A or the watermelon B is suggested, that is, the situation where the player pays the most attention. Can be recognized more effectively by the player.

  When a specific event occurs while all reels are rotating or when two or more reels are rotating, it is preferable that low-speed stop control is performed on the reel that stops after the specific event occurs. Even in such a case, the low speed stop control is performed in the situation where the player pays most attention, and the player can be more effectively recognized that the low speed stop control has been performed.

  Also, in this embodiment, when watermelon A or watermelon B is elected and is also elected for the low speed stop control, the watermelon elective suggestion effect is more likely than the case where the low speed stop control is not elected. In this case, the ratio at which the watermelon winning suggestion effect is executed before the second stop at which the low speed stop control can be executed is high. For this reason, when the low speed stop control is won at the time of winning the watermelon A or the watermelon B, the low speed stop control is realized by prompting the stop operation for winning the watermelon by the watermelon winning suggestion effect so as to pay attention to the fluctuation state of the reel. Can be effectively recognized by the player.

  As described above, the second embodiment of the present invention has been described. However, the present invention is not limited to the second embodiment, and changes and additions within the scope of the present invention are included in the present invention. Needless to say. Further, the same or similar configuration as the first embodiment has the same effect as that described in the first embodiment. Further, the modified example illustrated for the first embodiment is also applicable to the second embodiment.

  A third embodiment of the slot machine to which the present invention is applied will be described. The configuration of the slot machine according to the present embodiment includes the same configuration as that of the first embodiment described above, and therefore, different points will be mainly described here.

  There are two types of reel motor control when the reel is stopped in this embodiment, normal stop control and low-speed stop control. The former is a control for stopping the reel at the target stop position as soon as possible after detecting the stop operation. That is, the reel is stopped in a normal stop mode that requires a time that increases in proportion to the increase in the number of sliding frames as the time until the reel stops. The latter is the normal stop after the stop operation is detected. As compared with the control, the reel is slowly stopped at the target stop position, that is, as the time until the reel stops, the reel is stopped at a specific number of sliding frames (two frames in this embodiment) in the normal stop control. Time (114.24 to 147.84 ms or 152.32 in this example) exceeding the time required for stopping (71.68 to 105.28 ms in this example) 185.92) is a control to stop the reels at a special stop mode requiring. For this reason, in the latter case, even when the stop operation is performed at the same timing as the normal stop control and stopped at the same stop position, the time required for the reel to stop after the stop operation is increased.

  In the normal stop control, as shown in FIG. 63 and FIG. 64, the constant speed rotation step rate (2.24 ms) is maintained until the brake start position corresponding to the stop position is reached after the stop operation is detected. When the brake start position is reached, a step rate (3.36 ms) longer than the step rate (2.24 ms) during constant speed rotation is applied, the brake is applied to decelerate the rotor 32a, and the next step (4 In the step before step), all-phase excitation for exciting all excitation phases φ1 to φ4 is started. As a result, sudden braking is applied to the rotor 32a, and as a result of overshoot (step out), the rotor 32a stops at the stop position.

  In this embodiment, after all-phase excitation is performed in the normal stop control, it slips by overshooting for 5 steps. Therefore, as shown in FIG. 64, the brake is applied at a step 6 steps before the stop position in the rotation direction. And all-phase excitation is started 5 steps before the stop position.

  In the normal stop control, as shown in FIG. 62, when the stop operation is performed at the timing of 38 to 53 steps before the stop position, that is, the two-frame slip in which the low-speed stop control described later is performed, After the detection, the step rate is controlled to the same 2.24 ms step rate as the constant speed rotation for 32 to 47 steps, and the next step is controlled to a step rate of 3.36 ms longer than the constant speed rotation, Since it is controlled by excitation, it takes 71.68 to 105.28 ms from the detection of the stop operation to the excitation of all phases.

  The low-speed stop control further includes a low-speed stop control 1 and a low-speed stop control 2. Both the low-speed stop controls 1 and 2 are controls for slowly stopping the reel at a target stop position after detection of the stop operation, compared to the normal stop control. Even when the stop operation is performed at the same timing and stopped at the same stop position, the time required for the reel to stop after the stop operation is further increased.

  In this embodiment, the low-speed stop control 1 and the low-speed stop control 2 are applied only when two frames are selected as the number of sliding frames when the stop operation is performed. This is because if the low-speed stop control 1 or 2 is applied when the number of sliding frames is small, the rotation speed is suddenly reduced, and the vibration of the reel becomes conspicuous. On the other hand, the speed is low when the number of sliding frames is large. This is because when the stop control 1 and the low speed stop control 2 are applied, it becomes difficult to understand the difference from the normal stop control, and in the weight of the stepping motor and the reel applied in the present embodiment, two frames are described above. This is because it is most suitable in terms of points.

  In the low speed stop control 1, as shown in FIGS. 66 and 69, after the stop operation is detected, the constant speed rotation step rate (2) is reached until the brake start position corresponding to the stop position is reached in the same manner as in the normal stop control. .24 ms), but a step rate (3.24 ms) longer than the step rate (2.24 ms) at constant speed rotation from the brake start position positioned further forward than the brake start position in the normal stop control. .36 ms) is applied and the brake is applied to start the deceleration of the rotor 32a. At this time, instead of increasing the step rate uniformly as shown in FIG. 65, the rotor is smoothly applied by gradually applying a long step rate while alternately interlacing a long step rate and a short step rate. 32a is decelerated.

  Then, the step rate of 3.36 ms, which is 1.5 times the step rate of constant speed rotation (2.24 ms), is maintained up to the step before the start position of all phases, and the entire speed before the stop position in the rotation direction is maintained. All phase excitation is started at the phase start position (step before 2 steps). As a result, sudden braking is applied to the rotor 32a, and as a result of overshoot (step out), the rotor 32a stops at the stop position.

  In the low-speed stop control 1, since the rotational speed of the rotor 32a when starting full-phase excitation is slower and the inertial force is weaker than in the normal stop control, the all-phase start position of the low-speed stop control is the normal stop control. It is determined at a position closer to the stop position than the all-phase start position.

  In this embodiment, after performing all-phase excitation in the low-speed stop control 1, since it slips by overshooting by two steps, as shown in FIG. 69, all phases are two steps before the stop position in the rotational direction. Excitation will be started.

  In the low speed stop control 1, as shown in FIG. 65, after the stop operation is detected, the step rate is controlled to the same step rate of 2.24 ms as the constant speed rotation for 0 to 15 steps. .36 ms × 1, 2.24 ms × 3, 3.36 ms × 2, 2.24 ms × 2, 3.36 ms × 1, 2.24 ms × 1, 3.36 ms × 26 Since it is controlled by phase excitation, it takes 114.24 ms to 147.84 ms from the detection of the stop operation to the excitation of all phases. When stopping with two-frame slip in normal stop control, the time required for all-phase excitation after detecting the stop operation is 71.68 to 105.28 ms, even when stopping at the same stop position with the same two-frame slide As compared with the normal stop control, it takes a long time to stop after the stop operation is detected.

  In the low speed stop control 2, as shown in FIG. 67, after the stop operation is detected, the constant speed rotation step rate (2.24 ms) is reached until the brake start position corresponding to the stop position is reached as in the normal stop control. However, as with the low-speed stop control 1, the step rate (2.24 ms) at the constant speed rotation from the brake start position positioned further in front of the rotation direction than the brake start position of the normal stop control is maintained. A long step rate (3.36 ms) is applied and the brake is applied to start the deceleration of the rotor 32a. At this time, as shown in FIG. 67, the step rate is not uniformly increased, but a long step rate is applied alternately while alternately interlacing a long step rate and a short step rate, thereby smoothly rotating the rotor. 32a is decelerated.

  Then, after maintaining the step rate of 4.48 ms, which is twice the step rate of constant speed rotation (2.24 ms), until the step before the all-phase start position, all-phase excitation is started at the stop position. Thus, the rotor 32a sufficiently decelerated stops at the stop position without overshooting (step out).

  In the low-speed stop control 2, the brake is started at the same timing as the low-speed stop control 1. However, by making the step rate after deceleration longer than the low-speed stop control 1, the brake is stopped from the start of the brake rather than the low-speed stop control 1. It will take longer time.

  In the present embodiment, after all-phase excitation is performed in the low-speed stop control 2 as described above, all-phase excitation is started at the stop position in order to stop without overshoot.

  In the low speed stop control 2, as shown in FIG. 67, after the stop operation is detected, the step rate is controlled to the same step rate of 2.24 ms as the constant speed rotation for 0 to 15 steps. .36 ms × 1, 2.24 ms × 3, 3.36 ms × 2, 2.24 ms × 2, 3.36 ms × 1, 4.48 ms × 28 step rate, then all phase excitation Therefore, it takes 152.32 ms to 185.92 ms from the detection of the stop operation to the excitation of all phases. When stopping with two-frame slip in normal stop control, the time required for all-phase excitation after detecting the stop operation is 71.68 to 105.28 ms, even when stopping at the same stop position with the same two-frame slide As compared with the normal stop control, it takes a long time to stop after the stop operation is detected. Further, when stopping by two-frame sliding in the low-speed stop control 1, the time required for all-phase excitation after detection of the stop operation is 114.24 ms to 147.84 ms. It will take a long time to stop.

  As described above, in this embodiment, even when the stop operation is performed at the same timing and the stop operation is performed at the same position, when the low speed stop control is performed, the reel is decelerated compared to the normal stop control. The time required from the start to the stop becomes longer, and the stop position is reached slowly, so that the stop mode can be diversified.

  In addition, the low-speed stop control further includes a plurality of types of low-speed stop controls with different time required for stopping after detection of a stop operation, and the stop mode can be further diversified.

  In addition, when performing low-speed stop control, all-phase excitation starts at a position closer to the position where all-phase excitation starts in normal stop control, so that deceleration starts earlier than in normal stop control. Even if low-speed stop control with weak inertia force is performed, it is possible to stop at the same stop position as normal stop control, and the stop position varies depending on whether normal stop control or low-speed stop control is performed. Can be prevented.

  Even when low-speed stop control is performed, control is performed at the same step rate as constant-speed rotation until the brake start position is reached after a stop operation is detected. Regardless of the number of steps in which the operation is detected, if the number of sliding frames is the same, low-speed stop control can be performed with common control, and control can be prevented from becoming more complicated than necessary.

  The low-speed stop control shown in the present embodiment is a control method other than the above-excited control method as long as it is a control for slowly stopping the reel at a target stop position as compared with the normal stop control after detecting the stop operation. It may be performed by the control. For example, by making the excitation pattern different from the constant speed rotation at a stage earlier than the normal stop control, for example, by exciting the three excitation phases while keeping the excitation phase to be demagnetized originally excited, After decelerating the reel, it may be possible to lengthen the time required to stop than usual by performing all-phase excitation.

  In this embodiment, both the normal stop control and the low-speed stop control are configured to continue all-phase excitation for the same time after the start of all-phase excitation. The inertial force at the start of all-phase excitation is also weak, and the reel can be stopped reliably without continuing all-phase excitation for the same time as the normal stop control. The time until all the excitation phases are turned off after the start of all-phase excitation may be set shorter than the control. Moreover, if all phases are excited as in the case of the low speed stop control 2, it is sufficiently decelerated, and if it stops naturally, all phases are not excited and only all excitation phases are turned off. But it ’s okay.

  For example, when the hopper motor 34b is accompanied by a medal payout, the voltage is insufficient and the medal payout is waited until the all-phase excitation is released. As described above, the normal stop control is performed in the low speed stop control. By setting the all-phase excitation time shorter or not performing all-phase excitation, the time until the medal payout operation can be shortened when performing the low-speed stop control.

  In the first embodiment, the cherry combination is “ANY-ANY-cherry”. However, as shown in FIG. 70, the cherry of this embodiment has a “cherry” on one of the winning lines on the left reel. -When the combination of "BELL-ANY" is complete, that is, the symbol "CHERRY" is derived on one of the winning lines on the left reel, and "BELL" appears on the winning line where "CHERRY" stops on the left reel. When the symbol is derived, the game is won, and if the gaming state is the normal gaming state, RT1 to 4, one medal is paid out, and if the gaming state is RB1 to 3, 15 medals are paid out. It is.

  Further, in the above-described first embodiment, when the cherry is won, the stop control by the table method is applied at the first stop, and the stop control by the control method is applied after the second stop. In the cherry winning, only the left reel at the first stop applies the table type stop control, that is, the middle reel and the right reel at the first stop, all the reels at the second stop and the third stop For, stop control by the control method is applied.

  In addition, when the stop control is performed by the control method at the time of cherry winning, that is, when the stop control is performed for all reels at the time of the first stop, the middle reel and the right reel, and at the time of the second stop and the third stop, the stop is performed. The position is searched in the order of 2 → 0 → 1 → 3 → 4.

  FIG. 71 is a flowchart showing the control content of the low-speed stop determination process performed by the main control unit 41 in this embodiment.

  In the low-speed stop determination process of the present embodiment, first, it is determined whether or not the BB is being performed (Si2051) and whether or not the special combination confirmation notification has already been performed (Si2052).

  If it is determined in step S2051 that a bonus is being given, or if it is determined in step S2052 that a special role has been confirmed, the process is terminated. Control does not apply.

  On the other hand, if it is determined in step S2051 that the BB is not in progress, and it is determined in step S2052 that the special combination is not confirmed, it is determined whether cherry A is won in the internal lottery. However, even if it is determined that the cherry A is not won, the low speed stop control is not applied.

  If it is determined in step S2053 that cherry A is won in the internal lottery, the low speed stop control 1 is performed with the probability shown in FIG. 72, the low speed stop control 2 is performed, or the normal stop control is performed. A low speed stop lottery is performed (Si2054).

  Then, it is determined whether or not the low speed stop control 1 or the low speed stop control 2 is won (Si2055). When the winning of the low speed stop control 1 is determined in the step of Si2055, the low speed stop control flag indicating the low speed stop control 1 is set. When the winning of the low speed stop control 2 is determined, the low speed stop control 2 is set. Is set (Si2056), and if neither the low speed stop control 1 nor the low speed stop control 2 is won, the low speed stop control flag is not set.

  In the low speed stop lottery, as shown in FIG. 72, when only Cherry A is won, the probability of winning either of the low speed stop controls 1 and 2 (low speed stop control 1: 10%, low speed stop control 2: 5 %), The probability of winning either low speed stop control 1 or 2 when cherry A is selected with a special role (low speed stop control 1: 30%, low speed stop control 2: 30%) is set higher. ing.

  Further, when only Cherry A is elected, Cherry A together with the special role is more than the ratio (1/3 (5% / (5% + 10%)) of the slow stop control 2 among the slow stop controls 1 and 2 is won. The ratio (1/2 (30% / (30% + 30%)) that the low-speed stop control 2 of the low-speed stop controls 1 and 2 wins is set high.

  When the low-speed stop control flag indicating the low-speed stop control 1 is set, when two reels are selected as the number of sliding frames when the reel is stopped by a stop operation thereafter, the low-speed stop control 1 is applied. Become. When the low speed stop control flag indicating the low speed stop control 2 is set, the low speed stop control 2 is applied when two frames are selected as the number of sliding frames when the reel is stopped by a stop operation thereafter. It will be.

  If the low-speed stop control flag is not set, or if the low-speed stop control flag is set, but 0, 1, 3, or 4 is selected as the number of sliding frames, the reel is stopped by a stop operation. In this case, the normal stop control is applied.

  As described above, since the low speed stop control flag is not set during the BB or after the special role is confirmed, the low speed is not set even when the cherry A is elected during the BB or after the special role is confirmed. Stop control is never performed.

  FIG. 73 is a flowchart showing the control content of the stop switch process executed in the timer interrupt 4 of the timer interrupt process described above by the main control unit 41 in this embodiment.

  In the stop switch process of this embodiment, first, for all reels in the order of left, middle, and right, it is determined whether or not a stop operation position is set for the work on the corresponding reel, that is, whether a stop operation has been detected. If no stop operation is detected for all reels (Sk2101, Sk2102), the stop switch process is terminated and the process returns to the flowchart of FIG.

  On the other hand, if any stop operation of the reel is detected in the step of Sk2101, the process proceeds to the step of Sk2103.

  In step Sk2103, the virtual sliding frame table corresponding to the reel is referred to, and the region number serving as the stop position is specified from the region number including the step number of the stop operation position set for the work corresponding to the stop reel. .

  Next, it is determined whether or not the low speed stop control has already been executed in the game (Sk2104). Whether or not the low-speed stop control has already been executed is determined based on whether or not an executed flag to be described later is set. If it is determined in step Sk2104 that the low speed stop control has already been executed, the stop switch process is terminated and the process returns to the flowchart of FIG.

  If the low speed stop control has not been executed in the step of Sk2104, it is determined whether or not the number of steps specified in the step of Sk2103 is the number of steps (38 to 53) corresponding to two frames (Sk2105). If it is not the number of steps corresponding to two frames, the stop switch process is terminated and the process returns to the flowchart of FIG. 47. If the number of steps corresponds to two frames, is the low speed stop control 1 selected in the low speed stop lottery? That is, it is determined whether or not the low speed stop control flag indicating the low speed stop control 1 is set (Sk2106).

  If the low-speed stop control 1 is elected, the low-speed stop execution flag 1 for instructing the execution of the low-speed stop control 1 is set in the RAM 507, and an executed flag indicating that the low-speed stop control has been executed is set in the RAM 507. (Sk2107, Sk2108), the stop switch process is terminated, and the process returns to the flowchart of FIG.

  On the other hand, if the low speed stop control 1 is not won in the step of Sk2106, it is determined whether the low speed stop control 2 is won in the low speed stop lottery, that is, whether the low speed stop control flag indicating the low speed stop control 2 is set. Determination is made (Sk2109).

  If the low-speed stop control 2 is elected, the low-speed stop execution flag 2 for instructing the execution of the low-speed stop control 2 is set in the RAM 507, and the executed flag indicating that the low-speed stop control has been executed is set in the RAM 507. (Sk2110, Sk2108), the stop switch process is terminated, and the process returns to the flowchart of FIG.

  If the low speed stop control 2 is not selected in step Sk2106, the stop switch process is terminated as it is, and the process returns to the flowchart of FIG.

  When the low speed stop execution flag 1 is set in the stop switch process, the excitation time is controlled according to the low speed stop control 1 in the subsequent stop process, and the low speed stop execution flag 2 is set in the stop switch process. In such a case, the excitation time is controlled in accordance with the low-speed stop control 2 in the subsequent stop process.

  Further, in the stop switch process, even when the low speed stop control flag is set, if the low speed stop control is already executed in the game, the low speed stop control is not instructed. Thus, when the low speed stop control is executed on any of the reels, the low speed stop control is not executed on the subsequent reels.

  Next, the number of sliding symbols selected for each reel stop operation position at the time of cherry winning in which low speed stop control can be performed will be described.

  FIG. 74 is a diagram showing the number of sliding symbols for each reel that is selected when Cherry A is elected in a state where no special combination is carried over.

  The number of sliding frames on the left reel applied at the time of the first stop is the number of sliding frames developed using the sliding frame number data corresponding to the cherry. As shown in FIG. Slide pieces that draw “cherry” into the winning lines L2 to L5 with respect to the winning lines L2 to L5, that is, the area numbers 0 to 6 and 8 to 14 that can be drawn into the upper or lower stage, that make up the cherry in the range The number of the stop operation positions at which “Cherry” can be drawn into the pay lines L2 to L5 is determined by two frames.

  In addition, “cherry” cannot be drawn into the pay lines L2 to L5 in the drawing range of up to 4 frames, and the area numbers 7 and 15 to 20 are set to 2 frames. For this reason, when the left reel is the first stop reel when the cherry is won, two frames that can be controlled at a low speed at a rate of 11/21 are selected as the number of sliding frames. It has become.

  The number of sliding frames of the middle reel applied at the time of the first stop is the number of sliding frames specified by the stop position search process, and the “bell” constituting the cherry in the order of 2, 0, 1, 3, 4 is won. As a result of searching for the number of sliding frames to be drawn into the line, as shown in FIG. 74 (b), region numbers 2 to 4 are set as the number of sliding frames to be drawn into any of the winning lines L1 to L5, as shown in FIG. Two frames are specified for 6 to 11, 14 to 16, and 18 to 20, and 0 frames are specified for area numbers 0, 1, 5, 12, 13, and 17. For this reason, when the middle reel becomes the first stop reel when the cherry is won, two frames capable of performing the low speed stop control at a ratio of 15/21 are selected as the number of sliding frames. It has become.

  The number of sliding frames on the right reel applied at the time of the first stop is the number of sliding frames specified by the stop position search process, and any symbol is drawn into the winning line in the order of 2, 0, 1, 3, 4 As a result of searching for the number of sliding frames, two frames are specified for the region numbers 0 to 20, as shown in FIG. 74 (c). Therefore, when the right reel becomes the first stop reel when the cherry is elected, the ratio of 21/21, that is, two frames that can reliably perform the low speed stop control, is the number of sliding frames. It is to be selected.

  As described above, when the cherry A is selected, the low-speed stop control is performed at a rate higher than the number of sliding frames of the left reel and the middle reel selected as the number of sliding frames of the right reel at the first stop. Two frames that can be selected are selected.

  Although not specifically shown, the low-speed stop control can be performed at a rate greater than the number of sliding frames for the right reel and the number of sliding frames for the left reel and the middle reel even after the second stop. Two possible frames are selected.

  For this reason, in this embodiment, when Cherry A is elected, the ratio of stopping at two frames when the right reel stops is higher than that of the left reel or the middle reel.

  As described above, in the slot machine 1 according to the present embodiment, it is possible to perform the low-speed stop control for slowly stopping the reel at the target stop position after detecting the stop operation as compared with the normal stop control. If the number of sliding frames is small, the rotation speed will drop rapidly and the reel vibration will be noticeable. On the other hand, if the number of sliding frames is large, the difference from normal stop control will be difficult to understand. The number of sliding frames suitable for is limited.

  In this embodiment, the low speed stop control is performed only when two frames suitable for the low speed stop control are selected as the number of sliding frames, but the number of sliding frames is determined when the reel is stopped. The number of sliding symbols is limited to the number of sliding symbols suitable for low-speed stop control depending on the timing of the stop operation, and low-speed stop control is performed. Since opportunities are reduced, it is impossible to sufficiently enhance the interest of the player by providing low-speed stop control.

  For this reason, in this embodiment, the symbols (the left reel cherry and the middle reel bell) subject to winning determination in a specific reel (left reel, middle reel) only stop on one winning line and remain. When winning Cherry A, which accepts cherries that will win a prize regardless of the symbols stopped on the reels, low-speed stop control is performed, and when winning Cherry A, reels other than a specific reel, that is, winning cherries It is possible to perform low-speed stop control at a higher rate than a specific reel, that is, a reel in which the number of sliding frames is limited to draw “cherry” or “bell”. The number of sliding tops of the tops is selected, and the opportunity for low-speed stop control can be increased. It is possible to enhance the results basis.

  When there is an area where stop operation positions where two frames capable of performing the low speed stop control are selected and a stop operation position where two frames are selected are sparse in any reel May be arranged such that a symbol (a conspicuous symbol) is placed in an area where the stop operation position where two frames are selected is concentrated, and the symbol that is the indicator is notified. As a result, it is possible to prompt the user to perform a stop operation aiming at a region where the stop operation positions where two frames are selected are concentrated, thereby further increasing the chance of performing the low speed stop control.

  In addition, in this embodiment, as a special prize that will be awarded regardless of the symbols stopped on the remaining reels, the symbols subject to winning determination on a specific reel only stop on one winning line. One of the reels has a symbol for winning determination beyond the draw range (cherry on the left reel), and the other reel has a symbol for winning determination within the draw range. On the other hand, in the case of one reel among the specific reels, in order to stop the target symbol on the winning line, it is necessary to perform a stop operation at the timing of the drawing range of the symbol, For other reels, cherries that can stop the target symbol regardless of the timing of the stop operation are applied as special prizes. , One of the specific reels, that is, the symbol that is subject to winning determination is placed beyond the pulling range, and within the maximum pulling range to pull the target symbol to the maximum within the maximum pulling range depending on the operation timing The number of sliding frames of 2 frames capable of performing the low speed stop control is selected at a higher rate than the reels that need to select the number of sliding frames other than 2 frames of 0 to 4 frames of Therefore, even when the special prize having the above-described configuration is applied, it is possible to surely increase the opportunities for performing the low speed stop control.

  Also, in this embodiment, when winning Cherry A, the top priority is given to two frames that can be controlled at low speed for the reels other than the specific reel, that is, the right reel whose stop symbol does not affect the winning of cherry. The number of sliding frames is selected by a control method that searches for the number of frames, and the number of sliding frames is selected so that two frames are selected as the number of sliding frames as much as possible depending on the stop status and stop position of other reels. It is preferable because the ratio of the number of sliding frames of two frames can be increased without preparing in advance, but the number of sliding frames of two frames is also good for reels other than a specific reel when winning a cherry. The number of sliding frames with a high ratio is prepared in advance, and stop control is performed using these sliding frame number data. A configuration to enhance the case may be.

  Also, in this embodiment, when Cherry A is elected, when a special role with a transition to BB advantageous to the player is won, the speed is lower with a higher probability than when a special role is not won. If the stop control is won and the low-speed stop control is applied, that is, if the reel stops more slowly than usual after the stop operation, the possibility of winning the special role increases. It is possible to increase the player's expectation for winning the special role.

  In addition, Cherry A is a role that may be elected simultaneously with the special role, so the player's expectation due to the possibility of winning the special role suggested by the winning of Cherry A is controlled by the subsequent slow stop control. It can be further increased.

  In addition, when the special combination with the transition to BB advantageous for the player is selected among the low-speed stop control 1 and the low-speed stop control 2 that stops more slowly than the low-speed stop control, the special combination is not won. The low-speed stop control 2 is elected at a higher rate than the case, and when the reel stops more slowly than usual after the stop operation, the low-speed stop control 1 is slower than the case where the low-speed stop control 1 is applied. When control 2 is applied, that is, when the reel stops more slowly, the possibility of winning the special role increases, and when low-speed stop control is applied, pay attention to the speed. Can do.

  In this embodiment, when Cherry A is elected and it is determined that the low speed stop control is to be performed, if the low speed stop control is performed for any of the reels, then the remaining reels are stopped. Even when the number of sliding frames of two frames is selected as the number of sliding frames at that time, the low speed stop control is not performed. This is because, for example, when low speed stop control is similarly performed on all reels, it is difficult to identify whether low speed stop control is performed or normal stop control is performed. When the low speed stop control is performed on any of the reels as described above, the normal stop control and the low speed stop control are always mixed by not performing the low speed stop control for the remaining reels. By doing so, the difference becomes clear and the player can be surely recognized that the low-speed stop control has been performed.

  In this embodiment, when the low speed stop control is performed on any one of the three reels, the low speed stop control is not performed on the other reels, but the low speed stop is performed on a plurality of reels. The configuration may be such that the control is performed, and in such a configuration, the possibility of winning the special role suggested according to the number of reels for which the low speed stop control is performed may be changed.

  Also, in this embodiment, during the BB or after the special role is confirmed and notified, the period until the special combination wins, that is, the period during which no low speed stop control is performed suggests that the low speed Stop control is not performed, and it is possible to prevent the digestion efficiency of the gaming state from being reduced by performing the low speed stop control during such a period.

  In this embodiment, when the sub control unit 91 receives a reel stop command indicating the stop of the reel from the main control unit 41, a reel stop effect such as output of a reel stop sound is executed. On the other hand, it is possible to specify whether the main control unit 41 is the normal stop control, the low-speed stop control 1 or the low-speed stop control 2 from the reel stop command transmitted to the sub-control unit 91 when the reels are stopped. The sub-control unit 91 receives the reel stop command, and executes the reel stop effect different from the normal stop control when the low speed stop control 1 or 2 is specified from the received reel stop command.

  In the reel stop effect, for example, in the case of the normal stop control, the first stop sound having a predetermined length is output, whereas in the case of the low speed stop control 1, the second longer than the predetermined length is output. It is sufficient to output a stop sound. In this case, in the case of the low speed stop control 2, it is preferable to output a second stop sound that is longer than the second stop sound output in the case of the low speed stop control 1. Also, in the case of low speed stop control, the same sound effect as in normal stop control may be extended and output slowly, and in this way, the time until stop at the same number of sliding frames becomes longer. Can be recognized intuitively.

  Note that these reel stop effects are not limited to voice effects, but may be recognized as a longer time to stop at the same number of sliding frames depending on images, moving images, and LED lighting modes.

  Further, in this embodiment, the sub control unit 91 indicates the result of the low speed stop lottery, that is, the low speed stop control 1 is executed, the low speed stop control 2 is executed, or the low speed stop control is not executed. When the stop determination command is received, the result of the low speed stop lottery indicated by the low speed stop determination command is stored, and all the games in which the low speed stop control 1 or the low speed stop control 2 is stored are stored. If a reel stop command is received for a reel, and the low speed stop control 1 or 2 is not specified from any of the received stop commands, that is, even though a low speed stop lottery is won, two sliding frames are selected. If low-speed stop control is not performed because it was not selected, it is not determined that low-speed stop control is to be performed. Performing a slow stop suggesting effect never be executed when the quick stop control has been performed.

  In the low speed stop suggestion effect, the lighting mode of the reel LED 55 that irradiates the reels 2L, 2C, and 2R from behind is changed to a special mode.

  Note that the low speed stop suggesting effect is not limited to the effect mode in which the lighting mode of the reel LED 55 is changed, and it is possible to recognize that the low speed stop control is not performed although it is determined that the low speed stop control is performed. An effect mode may be used, and a display mode of the liquid crystal display 51, an audio output mode, and a lighting mode of a part or combination of LEDs may be applied.

  Further, in this embodiment, an effect that is not executed when low speed stop control is not determined as a low speed stop suggesting effect or when low speed stop control is performed on any reel is applied. However, for example, it may be configured to execute the low speed stop suggestion exceptionally when the low speed stop control is performed on the condition that the special role is elected. The low speed stop suggestion effect that is normally executed only when the low speed stop control is not performed is executed when the low speed stop control is performed, thereby indicating that the special role is won. It becomes possible.

  In the present embodiment, the number of sliding frames suitable for low-speed stop control is set to 2 frames with some margin in order to surely eliminate the possibility that the vibration of the reel will be greatly noticeable due to a sudden drop in the rotational speed. However, one frame may be applied as in the first embodiment as the number of sliding frames as a condition for performing the low speed stop control. If the number of sliding frames is less than one frame, the rotational speed is drastically reduced, causing vibration of the reel. Although it is difficult to suppress, if one frame is used, the vibration from the reel can be suppressed and the difference from the normal stop control can be made clearer.

  In addition, in this embodiment, when a cherry stops on the left reel on one of the winning lines and a bell stops on the middle reel, the cherry that wins regardless of the symbols stopped on the right reel is applied as a special prize. However, in any one of the reels, the special symbol stops on the winning line, and the winning combination (for example, Cherry-ANY-ANY, ANY-ANY-Cherry, etc.) is won regardless of the symbols stopped on other reels. It may be applied as a special prize.

  In addition, as a special prize, Cherry 1 consisting of a combination of “Cherry-Bell-ANY” (“Bell” in the middle reel is a pattern placed in the pull-in range) and “Cherry-Red 7-ANY” (in the middle reel) “Red 7” has a cherry 2 consisting of a combination of symbols placed beyond the pull-in range), and as a lottery subject for internal lottery, only a cherry 1 is won alone, and cherry 1 It is controlled so that only “Cherry-Bell-ANY” can be aligned on the winning line when a weak cherry is won, while a strong cherry is won. If “Reel 7” is stopped within the range that can be pulled into the winning line, “Cherry-Red 7-ANY” can be aligned on the winning line. Control is made so that “Cherry-Bell-ANY” can be aligned on the winning line when a stop operation is performed outside the range where “red 7” can be drawn into the winning line in the middle reel. The cherry 2 having such a configuration may be applied as a special prize.

  In this way, in the plurality of specific reels, the symbols that are subject to the winning determination are arranged beyond the drawing range (the cherry on the left reel, the red 7 on the middle reel), and are the targets on the plurality of specific reels. Even when the cherry 2 that needs to be stopped at a timing that becomes the drawing range of the symbol to stop the symbol on the winning line is applied as a special prize, a plurality of specific reels, That is, at a higher rate than the reels that need to select the number of sliding frames other than 2 frames out of 0 to 4 frames in the maximum drawing range in order to draw the target symbol to the maximum within the maximum drawing range depending on the operation timing, By increasing the number of sliding frames that can perform stop control, the number of sliding frames that can be selected is selected, thereby increasing the chances of low-speed stop control. It can be.

  In addition, when applying weak cherries and strong cherries as described above, the ratio of strong cherries winning at the same time as special roles is higher than weak cherries, or it provides benefits that are advantageous to players. In this case, it is preferable that the strong cherry win is given preference over the weak cherry win, so that even if the cherry is the same, the player's expectation will be sharpened by the difference in the display mode. Can be put out.

  As described above, the third embodiment of the present invention has been described. However, the present invention is not limited to the third embodiment, and modifications and additions within the scope of the present invention are included in the present invention. Needless to say. Further, the same or similar configuration as in the first and second embodiments has the same effect as that described in the first and second embodiments. Further, the modified example illustrated for the first and second embodiments can also be applied to the third embodiment.
