The coin inserted from the coin insertion slot 18 is detected by the inserted coin sensor 36, and the detection output is input to the I / O port 49 via the switch / sensor circuit 55. When a coin is paid out by the coin payout motor 38 (see FIG. 2), the payout coin is detected by the payout coin sensor 39, and the detection output is input to the I / O port 49 via the switch / sensor circuit 55. Is done.
When the surplus coin storage tank 41 becomes full with the stored coins, the fact is detected by the full tank sensor 42, and the detection output is input to the I / O port 49 via the switch / sensor circuit 55. The left reel 6L, the center reel 6C, and the right reel 6R rotate, and the reference position value (notch or the like) of each reel is set to the left reel position sensor 8L,
If detected by the middle reel position sensor 8C and the right reel position sensor 8R, respective detection signals are input to the I / O port 49 via the switch / sensor circuit 55.

The control unit 45 outputs a control signal to the following various devices. First, a reel drive control signal (step signal for a stepping motor) is output to the left reel drive motor 7L, the middle reel drive motor 7C, and the right reel drive motor 7R via the motor circuit 56. A coin payout control signal is output to the coin payout motor 38 via the motor circuit 57. A solenoid excitation control signal is output to the flow path switching solenoid 33 via the solenoid circuit 58. The display control signal is output to the game number display 25, the credit display 26, and the number-of-payouts display 27 via the LED circuit 59, respectively. Through the lamp circuit 60, the game effect lamp 24, the insertion instruction lamp 19, the effective line display lamps 21, 22, 23, the left operation effective lamp 11L, the middle operation effective lamp 11C, the right operation effective lamp 11R, the game over lamp 20, A lamp control signal is output to each of the game display lamps 64. Sound generator 5
0, and outputs a sound generation control signal to the speaker 28 via the amplifier 61.

The controller 45 is electrically connected to a card processor controller 80 provided in the card processor 76. A coin lending mode signal for designating whether or not coin lending is possible is output from the I / O port 49 to the card processing device controller 80 via the information output circuit 67. In response to the signal, the card processing device controller 80 turns on or blinks the lending permission indicator 70 when the lending mode is set. When the player presses the lending button 71, an operation signal is input from the lending switch 72 to the card processing device control unit 80, and a coin lending command signal is sent from the card processing device control unit 80 via the information input circuit 66. Input to the I / O port 49. In response to the signal, the control unit 45 outputs a control signal for paying out a predetermined number of coins to the coin payout motor 38 to perform control of renting out a predetermined number of coins. If a predetermined number of coins are lent, I / O port 4
9 outputs a coin lending signal indicating that a predetermined number of coins have been lent to the card processing device control unit 80 via the information output circuit 67. If the common card is inserted into the common card insertion / ejection port 79 and read by the card reader / writer 78, a control signal for displaying the value (remaining balance) of the player specified based on the read data is transmitted to the card. The data is output from the processing device controller 80 to the balance indicator 75. Further, provided that the card processing device control unit 80 and the control unit 45 are electrically connected, a card processing device connection signal is sent from the card processing device control unit 80 via the information input circuit 66 to the I / O port. 49 is input. The control unit 45 activates the game on condition that the card processing device connection signal is input. That is,
If this card processing device connection signal is not input,
The game is deactivated by not controlling the drive of the reel drive motors 7L, 7C, 7R, or not lending coins even if the lending button 71 is pressed. Note that a predetermined DC current is supplied from the power supply circuit 62 to the various devices and control circuits described above. Also,
The RAM 48 is configured to be supplied with a current for holding the memory from the backup power supply 63. Even if the supply of the current from the power supply circuit 62 is stopped due to a power failure or the like, the probability set value and the game state are determined. It is configured so that it can be stored for a period.

FIGS. 6 to 9 and FIGS. 12 to 17
6 is a flowchart for explaining the operation of the control circuit shown in FIG.

FIG. 6A shows a processing program executed when the power is turned on. The power-on of the slot machine is performed at the start of the operation of the game arcade, and during the operation of the game arcade, for example, when the power supply once falls due to a power outage and the power outage is restored again during the business operation of the game arcade. Can be considered. In FIG. 6, first, in step S (hereinafter simply referred to as S) 1, it is determined whether or not the reset switch is ON. The reset switch 4 is used to select whether the game over (stop) is set to function or not to function. If the reset switch 4 is turned on, the game over is started from S3. The mode is set to the null mode and the game over (stop) is set so as not to function. On the other hand, if the reset switch 4 is OFF, the mode is set to the game over mode in S2 and the game over (stop) is set to function. It should be noted that selection of whether or not to hit may be set by a dedicated switch. Next, the process proceeds to S4, where it is determined whether or not the key switch is ON. When the key switch 43 is ON, the mode is the probability setting mode and the key switch 43 is turned off.
In the case of F, the game mode is set, and when the key switch is OFF, the process proceeds to S5,
It is determined whether or not the AM is normal. If the AM is normal, the slot machine returns to the gaming state at the time of power-off. That is, since the RAM 48 shown in FIG. 4 is backed up by the backup power supply 63 at the time of a power failure or the like, the RAM 48 is executed at the time of a power fall such as the time of the occurrence of a power failure among the steps S33 to S200 described later. The steps of the program are stored in the RAM 48, and if YES is determined in S5, the program control returns to the stored step at the time of power-off.

On the other hand, when the program runs out of control,
A determination of NO is made in S5 and the process proceeds to S6, where the RAM is initialized and the set value of the winning probability is initialized. The initialization of the winning probability in S6 is initialized to a set value "3", for example. As will be described later, the setting values are prepared in six steps from “1”, which is the lowest probability, to “6”, which is the highest probability. Initialized to a certain “3”. As a result, when the slot machine is initialized due to a program runaway, etc., the probability is set to an approximately average probability, so that the winning probability is extremely high after the initialization due to the program runaway, etc. There is an advantage that it is possible to prevent an extreme change such as switching to an extremely low setting value.

On the other hand, if the key switch 43 is ON, that is, if it is operated in the probability setting mode, the process proceeds to S7, where the inserted coin flow path is switched to the return side, and the inserted coin is returned. Next, the process proceeds to S8, where it is determined whether or not a start operation has been performed. If not, the process proceeds to S10. In S10, it is determined whether or not a door switch operation has been performed. If there is no door switch operation, the current set value of the probability is displayed in, for example, the number-of-payouts display 27 in S13 and S8.
Return to Note that a dedicated set value display may be provided.

During the patrol in steps S8 to S13, the manager of the game hall or a staff member operates the door switch 44 (see FIG. 1) by one.
If the operation is performed twice, YES is determined in S10 and S
Proceeding to 11, the set value of the probability is incremented by "1". Then S
Proceeding to 12A, it is determined whether the current set value is “7”. Since the upper limit of the set value of the probability is set to “6”, when the set value becomes “7”, the process proceeds to S12B, the process of setting the set value to “1” again is performed, and the process proceeds to S13. move on. On the other hand, when the set value is not “7”, the process directly proceeds to S13, and the set value at the present time is displayed. The staff at the game arcade operates the door switch 44 so that the desired setting value is obtained while watching the display of the setting value of the probability in S13. When the desired set value is reached, the key switch 43 is turned off to switch to the game mode, and then the start lever 13 (see FIG. 1) is operated to turn on the start switch 13 so that S8 is performed.
Is determined as YES. As a result, since the key switch 43 has already been turned off, the process proceeds to S14, where processing of initializing the RAM, fixing the set value of the probability, and clearing the setting display is performed. Next, in S14A, the cumulative number of coins inserted and the number of coins paid out are set to “100” and “50” as initial values, respectively. This allows
The standard payout rate of the small role in the base game is 50/100
× 100% = 50%. Next, the process proceeds to a game start process.

FIG. 6B is a flowchart showing an interrupt program for the random counter updating process. This figure 6
The interrupt program shown in (b) is performed based on a pulse signal periodically input from the above-described pulse dividing circuit 53, and is executed, for example, once every 4 msec. First, at S15, the value R of the random counter is calculated.
Is updated by a predetermined number N. Then S1
Then, it is determined whether or not the value R of the random counter has become equal to or greater than a predetermined maximum value. Is determined. If one coin is not paid out as a result of display when the variable display device is stopped, the one game ends at the time when the variable display device is stopped. Ends. If one game has not ended, the interrupt program is ended as it is, and the next interrupt is awaited.

On the other hand, if the value R of the random counter is equal to or greater than the maximum value, the process proceeds to S17, and after the process of subtracting and updating the value R of the random counter by the maximum value is performed, the process proceeds to S18. Next, if the current interrupt program is to be executed at the timing when one game ends, S18
Is determined as YES, the process proceeds to S19, and a process of changing the value N to be added and updated in S15 based on the value R of the random counter is performed. This addition number N is selected from a plurality of types of prime numbers set in advance and one of prime numbers whose quotient is not an integer when the maximum value is divided by the prime number, and is changed by S19. By setting the addition number N in this way, the value R of the random counter
Will be able to take any number of values. Also,
Every time one game is over, the addition number N is changed to another prime number in S19, so that the value R of the random counter becomes a random value, and based on the value of this random counter, it is determined whether or not a winning will be described later. There is the advantage that a random decision can be made when making it.

FIG. 7A is a flowchart of an interrupt program showing an error check process. First, S20A
Is determined as to whether or not the card processing device 76 is connected. If the card processing device connection signal is not input, the process proceeds to S20B, and an error code "CC" indicating the error is displayed on the payout display 27. Is done. If the card processing device 76 is connected, the process proceeds to S20C, and it is determined whether or not the coins to be paid out are in a state of running out of coins. When it is determined that the coin is not out of coins, the process proceeds to S21, and it is determined whether or not the inserted coin is jammed. S if the inserted coins are not clogged
22 and the inserted coins are stored in the surplus coin storage tank 41.
A determination is made as to whether or not the tank is full (see FIG. 2). If the tank is not full, the process proceeds to S23, and whether or not coins paid out from the coin hopper 37 (see FIG. 2) are jammed. Is determined, if it is not clogged, the process proceeds to S24, where it is determined whether or not an error is occurring. If not, the interrupt program ends.

The number of coins paid out does not reach the expected number of coins to be paid out as a result of the end of one game, and the coin payout motor 38 is rotating. If no coin is paid out within a certain period of time, it is determined that the coin has run out and S2
A determination of YES is made by 0C, and an error code "HE" is displayed by the number-of-payouts display 27 (see FIG. 1) at S25. On the other hand, the inserted coin is jammed in the coin receiving path 35, and the inserted coin sensor 36 (see FIG. 2)
Is in a state where coins are continuously detected for a certain period of time or longer, a YES determination is made in S22, and S
26 displays an error code “CE”. Also,
When the coins inserted into the surplus coin storage tank 41 are full and the full tank sensor 42 (see FIG. 2) detects the full tank,
A determination of YES is made in S22, the process proceeds to S27, and an error code “CO” is displayed on the number-of-payouts display 27. If coins to be paid out from the coin hopper 37 are jammed and the paid-out coin sensor 39 (see FIG. 2) continuously detects coins for a certain period of time or longer, a YES determination is made in S23 and the process proceeds to S28. The error code “HJ” is displayed by the number-of-payouts display 27. If a motor error occurs as a result of the determination in S85H to be described later, a determination of YES is made in S23A, the process proceeds to S28A, and an error code “EE” is displayed on the number-of-payouts display 27. Further, after the error is determined in steps S20 to S23, during the period until the error code is cleared in step S32 described later, step S24 is performed.
Is determined to be YES, the process proceeds to S29, and S2 is performed.
The display of the error code displayed by any one of 5 to S28A is continued. That is, the display of the error code in S29 is performed until the front frame 1B in the open state is closed and the error code is cleared in S32 described later even after the cause of the error is removed by the staff at the game arcade. The display of the error code continues.

S25, S26, S27, S28, S28
After the processing of A or S29 is performed, the processing proceeds to S30, in which processing of interrupting the game of the slot machine and generating an error sound from the speaker 28 is performed.

When the staff at the game hall hears that the error sound is emitted from the speaker 28, the staff at the game hall opens the front frame 1B to remove the cause of the error of the slot machine, and further pays out. The type of the cause of the error that has occurred is identified from the error code displayed by the numerical display 27, and the operation that corresponds to the type of the cause of the error is performed to remove the cause of the error that has occurred. Then, after the work is completed, the staff at the game hall closes the front frame 1B. Then, the door switch 44 detects that the front frame 1B has been closed, and accordingly, a YES determination is made in S31. As a result, the control proceeds to S32, where the error code displayed by the number-of-payouts display 27 is cleared, the error sound is stopped, and the game is restarted from the game state at the time of occurrence of the interruption. Note that the detection output may be derived from the door switch 44 by pressing the door switch 44 with a finger or the like instead of actually closing the front member 1B, and the determination of YES may be made in S31.

FIGS. 7B and 8 are flowcharts showing the game start processing. At S33, a process of controlling the flow path switching solenoid 33 (see FIG. 2) to switch the flow path of the inserted coin to the take-in side is performed, and the process proceeds to S34 to determine whether or not a game switching operation has been performed. If there is no game switching operation, the process proceeds to S40, but if the player presses the game switching button 16, the process proceeds to S40.
The process proceeds to step S35, where it is determined whether or not the current mode is the credit game mode.
The processing for setting the credit game mode is performed by 6. On the other hand, if the credit game mode has already been set, the process proceeds to S37, a process for setting the coin game mode is performed, and the process proceeds to S38, where the credit counter is set to "0".
Is determined. This credit counter is used to count and store the number of coins given as a prize or the number of coins inserted by a player during a credit game.
The values are incremented and updated by “1” by 0 and S179, and are subtracted and updated by “1” by S39 and S56 described later. If this credit counter is "0", S4
The process proceeds to 0, but if it is "1" or more, the process proceeds to S39, where a process of paying out one coin and subtracting and updating the credit counter by "1" is performed, and the process returns to S38. The process of S39 is repeated until the credit counter becomes "0", and the payout of the number of coins corresponding to the count value of the credit counter is controlled. In other words, when the player switches to the coin game mode in the credit game mode, the player enters a coin number corresponding to the value of the credit counter added and stored during the credit game. Since it is necessary to pay out to the side, payout control is performed in S39. On the other hand, if the player presses the game switching button in the coin game mode at the present time, S3
Proceeding to 6, the credit game mode is set.

Then, the program proceeds to S40, in which it is determined whether or not a start operation has been performed. If the start lever 12 (see FIG. 1) has not yet been pressed, the process proceeds to S41A. In S41A, it is determined whether or not there is a coin lending command signal, and if not, the process proceeds to S41H. on the other hand,
When the player presses the lending button 71, the operation signal is input from the lending switch 72 to the card processing device control unit 80, and a coin lending command signal is sent from the card processing device control unit 80 to the control unit 45 of the slot machine 1. Is entered.
Then, the control proceeds to S41B, where a coin lending signal is output from the control unit 45 to the card processing device control unit 80, and the lending number is set to “50”. On the other hand, in response to the coin lending signal, the card processing device control unit 80 reduces the value (remaining amount) of the player specified by the record information of the inserted common card by 1,000 yen. In this embodiment, the lending unit of the coin is 1000.
Although the lending unit is 100 yen, the lending unit may be 100 yen, and the amount may be reduced by 100 yen every time 5 coins are paid out, and by performing this process ten times, 1000 yen worth of coins may be lent. In this way, the remaining amount of the common card is 1
Even if there is a fraction less than 000 yen, you will be able to lend the entire balance.

Next, the process proceeds to S41C, where it is determined whether or not the credit game mode is set. If the credit game mode is not set, S41F is executed.
A process of paying out one coin and a process of subtracting “1” from the number of loans are performed, and the process proceeds to S41G. On the other hand, if the player has pressed the credit operation button 14 to switch the slot machine 1 to the above-described credit game state, a determination of YES is made in S41C, the process proceeds to S41D, and the credit counter becomes “50”. A determination is made as to whether or not they are present. The credit counter is for counting the value of the player's possession (the number of coins, etc.) stored in advance for playing the credit game, and is incremented by "1" in S41D and S60 described later, and in S56. Is subtracted by “1” at a time. If the credit counter has reached the upper limit value of "50", the value of the player's possession cannot be stored in the credit counter any more. It is. On the other hand, the credit counter indicates the upper limit “5”.
If it is not "0", the process proceeds to S41E, where "1" is added to the credit counter and the number of loans is "1".
Perform subtraction processing.

In S41G, it is determined whether or not the number of loans is "0".
Returning to 1C, payout of coins or addition processing to the credit counter is performed again. By repeating this process, if the number of loans becomes "0", the process proceeds to S41H.

Next, in S41H, it is determined whether or not the number-of-insertion counter is "3". The number-of-insertion counter is used to count the number of coins inserted by the player from the coin insertion slot 18 or the number of times the player has pressed the credit operation button 14 during the credit game when playing one game, and This is for setting the number of bets to be bet on the game result, and is incremented and updated by “1” in S57 described later, and is cleared at step S33 at the start of the next game, although not shown. The bet amount is input and set in accordance with the count value of the insertion number counter, and when the bet number, that is, the count value of the insertion number counter is "1", an effective line (hit line) which is valid is set to one. When the count value is "2", the number is set to three, and when the count value is "3", the number is set to five. The upper limit of the count value of the insertion number counter is set to “3.” If the count value of the insertion number counter has not reached the upper limit “3” in S41, the process proceeds to S42, and the bonus game flag is set. It is determined whether or not it is set. The bonus game flag is set when the bonus game (regular bonus game) is actually started based on the display result when the variable display device is stopped in steps S162 and S169.
And is cleared in S188 when the bonus game is over. If the bonus game flag has not been set, S4
The process proceeds to step S7, but if set, the process proceeds to step S43.
It is determined whether or not the number-of-inputs counter is "0". That is, in the case of the bonus game, only one valid line of the combination of the variable display devices is valid as described above, so that only one bet game is permitted. Is controlled so as not to exceed the value. In S44, it is determined whether or not the game mode is the credit game mode. If the game mode is not the credit game mode, the process proceeds to S46, in which the coin flow path is switched to the return side and the coins inserted thereafter are returned. S after processing is performed
Proceed to 40. On the other hand, if it is in the credit game mode, the process proceeds to S45, where it is determined whether or not the credit counter has already reached its upper limit value of "50". Since the addition and updating of the credit counter cannot be performed any more, the process proceeds to S46, and a process of returning the inserted coin is performed.

In S47, it is determined whether or not a coin has been inserted. If so, the flow advances to S48 to determine whether or not the inserted number counter has already reached its upper limit of "3". If it is already "3", the process proceeds to S60, where a process of adding "1" to the credit counter is performed, and the process returns to S40. On the other hand, if the insertion number counter is not "3", the flow proceeds to S49, and it is determined whether or not the bonus game flag is set. If the bonus game flag is not set, the flow proceeds to S57. Since there is still room in the count value of the input number counter, a process of adding "1" to the count value is performed. If the bonus game flag has been set, the process proceeds to S50, where it is determined whether or not the insertion number counter is "0". In the case of the bonus game, since the upper limit value of the insertion number counter is "1" as described above, if the insertion number counter is "1", S6 is executed.
The process proceeds to 0, and a process of adding “1”, which is the number of coins inserted into the credit counter, is performed.
Next, the process proceeds to S58, in which a process of retrieving and storing the value R of the random counter updated and added according to the above-described random counter updating process is performed. This random value R
May be stored when it is determined in S40 that the start operation has been performed. Next, the process proceeds to S59A, a process for setting the expected payout number and the payout number to “0” is performed, and then proceeds to S59B. The number of coins to be paid out is the number of coins to be paid out to the player according to the type of the prize when a prize is determined based on the display result when the variable display device is stopped. , The number of coins actually paid out based on the winning.

At S59B, it is determined whether or not the number-of-insertion counter is "0".
Proceeding to C, the payline corresponding to the number of coins inserted in the previous one game is lit, and the process returns to S40.
On the other hand, if a coin has been inserted when the current one game is played, the inserted number counter is not “0”, so that S5
The program proceeds to 9D, in which an effective line is displayed according to the input number counter, and the process returns to S40. The display of this activated line is
If the value of the input number counter is "1", the center side 1
Only the effective line display lamps 21 for displaying the columns are lit, and when the insertion number counter is "2", the effective line display lamps 21 and 22 for displaying the three horizontal lines are displayed, and the insertion number counter is set to "2". In the case of "3", all of the effective line display lamps 21 to 23 for displaying five effective lines in two rows on three horizontal lines and two diagonal lines are lit.

Next, if it is determined in S47 that no coin has been inserted, the flow advances to S51 to determine whether or not the credit counter is "0". If not, the flow advances to S52. The process proceeds to determine whether or not a credit operation has been performed.
Proceed to 9B. On the other hand, if the credit counter is "0", the process directly proceeds to S59B without making a determination in S52. This is because when the credit counter is "0", no matter how much the player performs the credit operation by pressing the credit operation button 14, the game using the count value of the credit counter can be performed. This is because it is useless to determine whether or not a credit operation has been performed. Next, if there is a credit operation, the process proceeds to S53, where it is determined whether or not the number-of-insertion counter has reached "3". Ignore the operation and proceed to S59B. On the other hand, if it is not "3", the flow proceeds to S54, and it is determined whether or not the bonus game flag is set. If the bonus game flag is set, the flow proceeds to S55, and the insertion number counter is set. Is determined to be "0", and when the insertion number counter is "1", which is the upper limit in the bonus game, the credit operation is ignored and the process proceeds to S59B. On the other hand, when the insertion number counter is “0” or when the bonus game flag is not set, the process proceeds to S56, and after the credit counter is decremented by “1”, the process proceeds to S57, and “1” is added to the insertion number counter. Is performed.

As described above, the random value R of the random counter is read out in S58 every time a player inserts a coin from the coin insertion slot 18 in order to input and set the number of bets to bet on the game result in one game. When the player starts one game by inserting only one coin into the coin insertion slot 18, the random value R read based on the one inserted coin is stored and the random value R is stored. R is used to determine in advance what value is to be given when the variable display device is variably stopped. On the other hand, if the player inserts two coins from the coin insertion slot 18, the random value R read out based on the insertion of the first coin is erased and read out based on the insertion of the second coin. The updated random value R is stored, and the updated random value R is stored. Then, when the player performs a start operation, the value added content at the time of variable stop of the variable display device is determined in advance using the stored random value R. Further, if the player inserts three coins from the coin insertion slot 18, 1
Random value R read based on insertion of the second coin
Is updated to the random value R read based on the insertion of the second coin, and the updated random value R is further updated to the random value R read based on the insertion of the third coin, The finally updated random value R is stored and used for predetermining the content of value addition when the variable display device is variably stopped. Note that the extraction of the random value R may be performed by a start operation. On the other hand, at the time of the credit game, the random value R of the random counter is read and stored in S58 up to three times each time the player presses the credit operation button 14 to set and input the number of bets. The storage of the random value R is also performed by reading the random value R twice, as described above.
The first read random value R is updated and stored as the second read random value R, and the random value R becomes 3
If the random value R is read twice, the random value R read second time is updated to the random value R read third time, and the last random value R is stored.

Next, if the player presses the start lever 12, YES is determined in S40 and S61 is reached.
It is determined whether or not the number-of-inputs counter is "0". If it is "0", the flow proceeds to S41. The coin flow is controlled to switch the coin flow path to the return side, and the process proceeds to reel rotation control thereafter. As a result of the processing in S62, coins inserted thereafter are returned to the coin storage tray 30.

FIGS. 9 and 12 are flowcharts showing a program for reel rotation processing. First, it is determined from S63 whether one game timer has expired. The one game timer is for measuring a minimum time (for example, 4.1 seconds) that must elapse from the start of one game to the end thereof.
Set by S65. In addition, the time set in one game timer is changed according to the bet amount, and the bet amount is one bet,
In the case of two bets, a shorter time may be set than in the case of three bets. If the one game timer has not expired, the process proceeds to S64, where a timer end waiting sound is generated from the speaker 28 to notify the player that the one game timer has not expired. On the other hand, if the one game timer expires, the process proceeds to S65, where the one game timer is newly set, the operation invalidation timer is set, and the rotation of all reels is started. This operation invalidation timer is, as described above,
This is a timer for measuring the time for invalidating the operation of the stop buttons 9L, 9C, 9R even when the stop buttons 9L, 9C, 9R are operated.

Next, the flow proceeds to S66, in which a predetermined operation is performed using the stored random value R. The predetermined calculation means adding, subtracting, multiplying, or dividing a predetermined value to the random value R, squaring or squaring the random value R, or substituting the random value R for a predetermined function. To calculate the answer.
Next, the process proceeds to S67, in which the result of the calculation is represented by the number of inputs, the set value,
A process of comparing with the winning allowable value according to the probability variation counter / small winning combination determination mode is performed.

This winning allowable value is, for example, as shown in FIG.
As shown in (c), (d) and FIG. 11, the big bonus game (BB) winning allowable value, the regular bonus game (RB) winning allowable value, the re-game winning allowable value, and the small role winning allowable value are set. It is composed of four types. These winning allowable values are stored in the ROM 47 in the form of a table. The winning allowable value shown in FIG. 10 (c) is a three-bet bet, the small winning combination determination mode is “normal”, and the probability variation counter is “0”.
Shows a case where the probability set value is “4”. This small role determination mode is set to “normal” when the value grant status to the player by the slot machine 1 is higher than the predetermined standard value, and is set to “normal”. If it is low, it is set to "at the time of high probability", and is used for feedback control of the small-part occurrence probability according to a standard value. Also, "at the time of the big bonus"
Is controlled such that a small win occurs with a high probability. The probability variation counter is for storing how many times the occurrence probability of the big bonus game is to be improved, and is set to “2” by S195N described later, and is set to “1” by S195P. When the probability is not improved, “0” is stored. "Probability setting"
Is a value set according to the operation of the key switch described above (see S9 to S13).

As shown in FIG. 10C, when the calculated value in S66 is less than the big bonus winning allowable value b ₀ , it corresponds to the big bonus game winning, and when the calculated value is more than b ₀ , the regular bonus game winning allowable b is applicable to the regular bonus game in the case of less than _1, corresponds to the re-game winner in the case of a re-game winning less than the allowable value b ₂ in b ₁ or more,
If b ₂ or more than 15 pieces of Small Win winning tolerance b ₃ may correspond to small combination winning be paid 15 coins, in the case of 8 pieces of Small Win winning than the permissible value b ₄ in b ₃ or more coins Is equivalent to the small part winning where 8 pieces are paid out, and 6 pieces of small part winning allowance b ₅ when b ₄ or more.
If it is less than this, it corresponds to the small role election that pays out 6 coins,
In the case of b ₅ less than 3 pieces of Small Win winning tolerance b ₆ above may correspond to a small win prize be paid 3 coins, corresponding to off in the case of more than b _6. In addition, A ₃₄ , shown in FIG.
B ₃₄ , C ₃₁ , D ₃₁ , E ₃₁ , F ₃₁ and G ₁₁ are shown in FIG.
These are the values shown in (a) and (b). Also, R _MAX is
This is the upper limit value that the calculation result using the random value R can take.

Numerals 1 to 6 shown in the leftmost column of FIG. 10A indicate probability setting values, and numerals 1, 2, and 3 shown in the top row are coins. The inserted number, that is, the number of bets, is shown, BB is a big bonus game, and RB is a regular bonus game. "Normal time" indicates that the occurrence probability of the big bonus game is in the normal state, and "fluctuation" indicates that the occurrence probability of the big bonus game has improved. The numbers 1, 2, and 3 shown in the top row of FIG. 10B indicate the number of coins inserted, that is, the number of bets, and "normal", "high probability", and "BB" shown in the row below. "
Indicates whether the small role determination mode is normal, high probability, or big bonus.

In the case of FIG. 10C, the bet is three, the small win determination mode is normal, and the value of the probability variation counter is "0".
Since the probability setting is “4” in FIG.
Numbers set-up number "4" is "3" in the probability of occurrence of big bonus game is described in the column corresponding to "normal" in (a), i.e., the A ₃₄ as big bonus game winning tolerance, B ₃₄ is used as a regular bonus game winning tolerance. In FIG. 10B, the number of insertions is “3”, and the small combination determination mode is the value described in the normal column, that is, the small combination winning allowable value for paying out 15 coins is C ₃₁ , 8. D ₃₁ as a small part winning allowable value for paying out three coins, E ₃₁ as a small part winning allowable value for paying out six coins, and F as a small part winning allowable value for paying out three coins.
_31, G ₁₁ as a re-game winning allowable value is used. Note that the data shown in FIGS. 10A and 10B is stored in the ROM 47 in the form of a table.

FIG. 10D shows a small-coin judgment mode in which three bets are placed.
Is "high probability" and the value of the probability fluctuation counter is "0"
Shows a case where the probability setting value is “4”. in this case
According to FIGS. 10A and 10B, the big bonus
Game winning tolerance b₀= A₃₄, Regular Bonus Game
Winning tolerance b₁= B₀+ B₃₄, Re-game winning tolerance b
_Two= B₁+ G₁₁, Pay out 15 coins, small-lot winning allowance
b_Three= B_Two+ C₃₂, Pay out 8 coins, small-lot winning allowance
b_Four= B_Three+ D₃₂, Paying 6 coins, small-lot winning allowance
b_Five= B_Four+ E₃₂, Paying 3 coins, small-lot winning allowance
b₆= B_Five+ F₃₂Becomes

FIG. 11 (a) shows a three-betting and small-course determination mode.
Is “normal” and the value of the probability fluctuation counter is other than “0”
In this case, the case where the probability setting value is “4” is shown. This place
In this case, according to FIGS. 10 (a) and 10 (b),
Game winning allowance b₀= A ₄₄, Regular bonus game
Team winning allowance b₁= B₀+ B₃₄, Re-game winning allowance
b_Two= B₁+ G₁₁, Pay small coins to pay 15 coins
Value b_Three= B_Two+ C₃₁, Paying 8 coins is allowed
Value b_Four= B_Three+ D₃₁, Paying 6 coins, small role winning allowed
Value b_Five= B_Four+ E₃₁, Paying 3 coins, small part winning allowed
Value b₆= B_Five+ F₃₁Becomes

FIG. 11 (b) shows a case where the bet is three, the small win determination mode is "high probability", the value of the probability variation counter is other than "0", and the probability set value is "4". 11 (b) according to the tables of FIGS. 10 (a) and 10 (b).
As shown in the table, each winning allowable value is determined. FIG.
(C) is a three bet and the small part determination mode is “high probability”
Indicates that the big bonus game winning flag is set or the regular bonus game winning flag is set. In this case, there is no big bonus game winning allowable value and no regular bonus winning allowable value. FIG. 11D shows a case in which the small winning combination mode is “Big Bonus” with three bets. In this case, there is no big bonus winning allowable value and no re-game winning allowable value. In this case, as the bonus game winning allowable value, the numerical value in the bottom row of FIG. 10B is used.

With the above-described configuration, the probability of occurrence of small wins is higher when the small win determination mode is “high probability” than in “normal”, and the small win determination mode is “big bonus”. In the case of "time", the small-combination occurrence probability further increases and the bonus game occurrence probability also increases. Also,
The big bonus game occurrence probability, the bonus game occurrence probability, the small role occurrence probability, and the re-game occurrence probability are higher for the two bet than the one bet and the three bet than the two bet. In addition, the occurrence probability of the big bonus game is higher when the value of the probability variation counter is other than “0” than when the value is “0”. As shown in FIG. 10A, in this embodiment, when the value of the probability variation counter is not “0” and the probability of occurrence of the big bonus game is improved, the number of coins inserted is three, ie, Limited to the case of three bets. By setting the data shown in FIGS. 10A and 10B to appropriate values, the small-part payout rate, that is, (each small-part winning probability ×
(Coin payout number) / coin insertion number × 100% can be set to an appropriate value. For example, 50% when the small role determination mode is “normal”, and 10% when “high probability”
0%, 150% at the time of "Big Bonus" and so on.

Next, the process proceeds to S68, where it is determined whether or not the bonus game flag is set. If the bonus game flag is not set, the process proceeds to S71 to determine whether or not the big bonus game flag is set. Is determined, and if the big bonus game flag is not set, the process proceeds to S74. In S74, a reel rotation sound is generated from the speaker 28, and then S
The process proceeds to 75, where it is determined whether or not the big bonus winning flag or the bonus winning flag has been set. If the flag has already been set, the process proceeds to S81, but if not, the process proceeds to S76.

In S76, the result of comparison in S67 is
Whether or not the calculation result using the random value R is included in the big bonus winning allowable value, that is, 0 ≦ calculation result <b ₀
Is determined, and if it is included, S
Proceeding to 77, the big bonus winning flag is set and proceeding to S80. On the other hand, if the result of the comparison in S67 is that the calculation result using the random value R is not the big bonus winning allowable value but is included in the bonus winning allowable value (b
_{In the case of 0} ≦ calculation result <b ₁ ), YES is determined in S78, the process proceeds to S79, a bonus winning flag is set, and the process proceeds to S80. In S80, the game effect lamp 24
(See FIG. 1) is turned on, and then S8
Go to 5. By the processing of S80, a notification that a big bonus or a bonus has been won is issued. Note that S8
Instead of turning on the game effect lamp 24 by 0, a dedicated indicator may be provided to notify that a big bonus has been won or that a bonus has been won. Further, a predetermined sound is generated from the speaker 28. The notification may be made. As a result of the processing in S80, the player is in a state of recognizing that the big bonus has been won or the bonus has been won. Since the reach sound is not generated unless the bonus is won (S108 to S110), the player is notified of the reach state despite the possibility of becoming a big bonus game or a bonus game. Can prevent discomfort.

If NO is determined in S78, the process proceeds to S81, in which it is determined whether or not the comparison result in S67, the calculation result using the random value R is included in the re-game winning allowable value, and the determination is made. If not, the process proceeds to S83, but if it is included (b ₁ ≤ operation result <b ₂ ), S
Going to 82, the re-game winning flag is set and S85
Proceed to. According to the setting of the re-game winning flag in S82, as described later, control is performed so that the variable display device is automatically variably started by a start operation without inserting a coin and a game can be re-started. In S83, S6
As a result of the comparison of 7, it is determined whether or not the calculation result using the random value R is included in each of the small winning combination allowable values. If the calculation result is not included, the process directly proceeds to S85. (B ₂ ≦ calculation result <b ₃ , b ₄ , b ₅ , b ₆ )
Proceeds to S84, a winning flag corresponding to the type of the included small win is set, and the process proceeds to S85.

Next, if the bonus game flag has been set, a YES determination is made in S68 and S
Proceeding to 69, it is determined whether or not the comparison result of S67 and the calculation result of the random value R are included in the JAC winning allowable value. In other words, the determination of YES in S68 means that the game state of the slot machine is in the bonus game, and the display result when the variable display device is variably stopped during the bonus game is "JAC". In this case, as described above, a prize is generated during the bonus game and 15 coins can be paid out, and it is determined in S69 whether or not a prize is generated during the bonus game. It is. When the determination at S69 is NO, the process proceeds directly to S85, but when the determination is YES, the process proceeds to S85.
Proceeding to 70, the JAC winning flag is set. As a result, as will be described later, control for generating a winning during the bonus game is performed.

On the other hand, when the big bonus game flag is set instead of the bonus game flag, S
A determination of YES is made by 71 and the process proceeds to S72, and S6
7, it is determined whether or not the calculation result using the random value R is included in the bonus game allowable value. When the game state of the slot machine is during the big bonus, the display result when the variable display device is variably stopped is "J.
If the combination of the stop symbols of "AC" is reached, the bonus game in the big bonus game is started as described above. Therefore, in S72, whether or not to generate the bonus game in the big bonus game is determined. Is determined. And S7
If NO is determined in S2, the process proceeds to S83, but if YES is determined, the process proceeds to S73 and J
The AC winning flag is set, and the routine proceeds to S85.

Next, in S85, it is determined whether or not the operation invalidation timer has expired, and the process waits until the operation invalidation timer expires. The time set in this operation invalidation timer is from S68 to
This is a time (for example, 1 second) longer than the time required for performing the process of S84. When the operation invalidation timer expires, the process proceeds to S86, in which the reel stop timer is set, and control for turning on the operation effective lamps 11L, 11C, 11R (see FIG. 1) is performed.

Next, in S85A, it is determined whether or not the left reel reference position has been detected. If not detected, the flow proceeds to S85C, where it is determined whether or not the middle reel reference position has been detected, and not detected. In this case, the process proceeds to S85E to determine whether or not the right reel reference position has been detected. If not, the process proceeds to S85G to determine whether the left, middle, and right reference position detection flags have been set. If not set, the process proceeds to S85H,
It is determined whether or not the operation invalidation timer has expired, and if not, the process returns to S85A. In the course of the loop of S85A to S85H, the left reel reference position 6
If La is detected by the left reel position sensor 8L, S
Proceeding to 85B, the left reference position detection flag is set.
Also, the middle reel reference position 6Ca is the middle reel position sensor 8
If detected by C, the process proceeds to S85D, where a middle reference position detection flag is set. Also, the right reel reference position 6R
If a is detected by the right reel position sensor 8R, S8
Proceeding to 5F, the right reference position detection flag is set. If all of the left, middle, and right reference position detection flags are set, YES is determined in S85G, and S85 is performed.
Proceed to 85I. On the other hand, if the operation invalidation timer set in S65 expires without detecting the left, middle, and right reel reference positions, the reel is not rotating or the reel position sensor has failed. Is assumed, a motor error occurs and the operation shifts to an operation when an error occurs.

At S85I, the operation waits until the operation invalidation timer expires, and at the stage when the operation invalidation timer expires, the process proceeds to S86, where the reel stop operation is validated. As described above, the stop operation is enabled after the operation invalidation timer expires after the reference position of each reel is detected. Also, instead of S85I, it may be determined whether the number of steps of the stepping motor for rotating the reel has reached a predetermined value as in S85J, wait until the number of steps reaches S85I, and proceed to S86 when the number is reached. In S86, a reel stop timer is set, and control is performed to turn on the operation valid lamps 11L, 11C, and 11R (see FIG. 1). The reel stop timer is a timer for measuring a predetermined time and automatically stopping the reel when the player does not operate the stop buttons 9L to 9R at all. Next, the process proceeds to S87, in which it is determined whether or not all the reels have stopped. If the reels have not yet stopped, the process proceeds to S88, in which it is determined whether or not the reel stop timer has expired. If it is determined that the reel stop timer has expired, the flow proceeds to S95, where the left, middle, and right reel stop flags are set, and the flow proceeds to S96. On the other hand, if the reel stop timer has not expired, the flow proceeds to S89 and
A determination is made as to whether or not a left reel stop operation has been performed. If not, a determination is made in S91 as to whether or not a middle reel stop operation has been performed. If not, a determination is made in S93 whether or not a right reel stop operation has been performed. , Otherwise S
Go to 96. On the other hand, if the player presses the left stop button 9L, a determination of YES is made in S89, the process proceeds to S90, the left reel stop flag is set, and the left reel is controlled to stop. Next, if the player presses the middle stop button 9C, a determination of YES is made in S91, the process proceeds to S92, a middle reel stop flag is set, and the middle reel is stopped and controlled. If the player presses the right stop button 9R, a determination of YES is made in S93, the process proceeds to S94, the right reel stop flag is set, and the right reel is controlled to stop. Next, the player operates the stop buttons 9L, 9C,
A case where two or more of the 9Rs are simultaneously pressed will be described.
For example, when the player sets the left stop button 9L and the middle stop button 9L
If C is pressed simultaneously, a determination of YES is made in S89, the process proceeds to S90, a left stop flag is set, and the left reel is controlled to stop as described later, and a determination of YES is made in S91. In S92, the middle reel stop flag is set, and the middle reel is controlled to stop as described later. Even if the player presses a plurality of stop buttons at the same time, the reel corresponding to the pressed stop button is controlled to be stopped, and the stop operation of one of the buttons is invalidated. There is no inconvenience. This is the stop button 9L, 9
The same applies to the case where three of C and 9L are simultaneously pressed.

Next, in S96, it is determined whether or not the left reel stop flag is set. If not, in S100, it is determined whether or not the middle reel stop flag is set. If not, it is determined in S104 whether or not the right reel stop flag is set, and if not, the process proceeds to S108. If the left reel stop flag is set, the process proceeds to S97, where it is determined whether or not the left reel is rotating. If the left reel is rotating, S9 is performed.
After the reel stop control is performed by step 8, the process proceeds to S99, and the left reel stop flag is cleared. On the other hand, if the left reel has already stopped, the determination of NO is made in S97, and the process directly proceeds to S99. Since the same processing as that of S96 to S99 described for the left reel is performed for the center reel and the right reel, the description is not repeated here. Next, at the stage when all the reels have stopped, S87
Is determined as YES, and the process shifts to the winning determination process shown in FIG.

On the other hand, if NO is determined in S104, the process proceeds to S108, and it is determined whether or not the symbol displayed by any of the two stopped reels is a symbol in the reach state. You. The reach state is a state in which any one of the plurality of variable display units 5L, 5C, 5R is still variably displaying, and the display results of the already stopped variable display units are "AAA", "BBB". "Means a predetermined display state that satisfies a condition for a combination of specific identification information such as"". If it is determined in step S108 that the vehicle is not in the reach state, the process proceeds to step S87. If it is determined that the vehicle is in the reach state, the process proceeds to step S109.
It is determined whether or not the big bonus winning flag or the bonus winning flag is set. If neither is set, the process proceeds to S87, but if any is set, the process proceeds to S110. After the reach sound is generated from the speaker 28, the process proceeds to S87.
By issuing the reach sound, the player's expectation that the combination of the specific identification information may be established depending on the display result when the variable display unit currently variably displaying the variable display is stopped is effective. It can be lively.
In addition, in addition to or instead of generating the reach sound from the speaker 28, a display indicating that the reach state has occurred may be performed. In addition, the notification at the time of the reach may be performed only when the big bonus winning flag is set, or the notification may be performed only at the time of the reach of which one of the winning flags is set.

FIGS. 13 to 15 show steps S98 and S10.
2 is a flowchart showing specific contents of reel stop control defined in S106. First, in S111, a process of confirming the current symbol number is performed. This symbol number is 0-20 (see FIG. 3) 21 as described above.
There are reel drive motors (stepping motors) 7
L, 7C, 7R feeding steps and reel position sensor 8
It is confirmed based on the L, 8C, and 8R reference position detection signals. Next, it is determined in S112 whether the bonus game flag is set. When the bonus game flag is set, the process proceeds to S113, and it is determined whether or not the other two reels are stopped. The other two reels mean reels other than the reel for which the stop control is currently being performed. And
At the stage where the other two reels have not stopped yet, S12
The process proceeds to 0, control is performed to stop the JAC symbols within four symbols from the current symbol number confirmed in S111 on the activated pay line, and the process proceeds to S152. In the case of a slot machine, a limited very short time of about 0.2 seconds after the player presses the stop buttons 9L, 9C, 9R in order to prevent the stop control manner from becoming unnatural. The corresponding reel must be stopped within a predetermined time, and the rotation angle at which the reel can rotate within a very short predetermined time is about four symbols. Therefore, it is impossible to stop-control a JAC symbol that is four or more symbols ahead of the stop button on the effective activated line after the stop button is pressed. Then, the JAC symbol is controlled to stop on the activated line. Note that FIG.
As shown in the figure, when the current symbol number is not a JAC symbol, the symbol array is configured such that the JAC symbol always exists within a range of four symbols away from the current symbol number. As described above, if the reel to be stopped is not the last reel, the JAC symbol is controlled to be stopped on the activated pay line regardless of whether the JAC winning flag is set or not. Yes, this allows the player to look closely at subsequent reel stops with hope. Next, the process proceeds to S152, in which the operation valid lamp corresponding to the stopped reel among the operation valid lamps 11L, 11C, 11R is turned off, and control for emitting a reel stop sound from the speaker 28 is performed.
It returns to either 103 or S107.

If the bonus game flag is set and the other two reels are stopped, the process proceeds to S104, where it is determined whether or not the JAC winning flag is set. The process proceeds to S115 if it is not set. S1
At 15, JA which is within 4 symbols from the current symbol number
The C symbol is removed from the active line where the symbol is valid, and the process is stopped. Then, the process proceeds to S152. In other words, since the JAC winning flag is not set, it is not possible to establish a combination of JAC symbols on the activated line that is activated, and thus the JAC symbol is forcibly shifted from the activated line that is activated. And stop it.

Next, if the bonus game flag has not been set, the process proceeds to S116, where it is determined whether or not the big bonus game flag has been set.
If the big bonus game flag has been set, the process proceeds to S117, and it is determined whether the JAC winning flag has been set. If the JAC winning flag has been set, the process proceeds to S118, and another reel A determination is made as to whether it is stopped. When the other reels are not stopped, the process proceeds to S120, and the control for stopping the JAC symbol on the activated line is performed as described above. On the other hand, if the other reels have already stopped, the process proceeds to S119, and 4 reels are counted from the current symbol number.
J of the reel that stops the JAC symbol within the symbol tip
The stop is performed on the activated line of the AC symbol, and the stop control is performed so that the combination of the JAC symbols is established on the activated activated line, and then the process proceeds to S152.

On the other hand, if the big bonus game flag has not been set or if the JAC winning flag has not been set, the flow advances to S121 to determine whether or not the re-game winning flag has been set. If the re-game winning flag is set, the process proceeds to S122, where it is determined whether or not another reel is stopped. If the other reel is not yet stopped, S123 is performed.
Go to the JAC within 4 symbols from the current symbol number
Control is performed to align and stop the symbols on the active line of the stopped JAC symbol, and the process proceeds to S152. On the other hand, when the other reels are stopped, the process proceeds to S124, in which control is performed so that the JAC symbols within four symbols from the current symbol number are aligned and stopped on the active line of the stopped JAC symbol, and S152 is performed. Proceed to.

On the other hand, if the re-game winning flag has not been set, the flow advances to S125 to determine whether the big bonus winning flag has been set. S if the big bonus winning flag is set
Proceeding to 126, it is determined whether or not another reel is stopped. If the other reel is not stopped yet, S
In step 127, it is determined whether or not there is a big bonus symbol (A in this embodiment) within four symbols from the current symbol number, and if so, the big bonus symbol is stopped on the activated line by S128. After that, the process proceeds to S152. On the other hand, when there is no big bonus symbol within four symbol destinations from the current symbol number, the start of the big bonus game in the current game is abandoned, and the process proceeds to S139. Note that S1
Even if the determination is NO at 27, the control to stop the big bonus symbol on the activated line again in the next game is attempted because the big bonus winning flag is still set. The attempt is repeatedly executed until the big bonus symbol actually stops on the activated line.

Next, if it is determined in S126 that another reel is stopped, the flow advances to S129 to determine whether or not there is a big bonus symbol on the activated line. It is determined whether or not the big bonus symbol that can be stopped on the active line of the stopped big bonus symbol is within four symbols from the current symbol number. Control is performed to stop the stopped reel on the activated line of the big bonus symbol. on the other hand,
If it is determined in S130 that the big bonus symbol that can be stopped on the active line of the stopped big bonus symbol is not within four symbols ahead, the start of the current big bonus game is abandoned as described above. Proceeding to S139, an attempt is made to stop the variable display device so that the big bonus game is started again in the next game.

When the big bonus winning flag is not set, the process proceeds to S132, and it is determined whether the bonus winning flag is set. When the bonus winning flag is set, the process proceeds to S133,
A determination is made as to whether another reel is stopped. When the other reels are not stopped, the process proceeds to S134, and it is determined whether there is a bonus symbol (B in this embodiment) within four symbols from the current symbol number, and if there is, the process proceeds to S135. Control is performed to stop the bonus symbol on the activated pay line, and the process proceeds to S152.
On the other hand, if it is determined in S134 that there is no bonus symbol, the process proceeds to S152. Next, if it is determined in S133 that another reel is already stopped, the process proceeds to S136.
It is determined whether or not there is a bonus symbol on the activated line, and if not, the process proceeds to S139. On the other hand, if there is a bonus symbol on the activated line, the process proceeds to S137, and it is determined whether or not a bonus symbol that can be stopped on the activated line of the stopped bonus symbol is within four symbols from the current symbol number. If not, the process proceeds to S139. If there is, the process proceeds to S138. Control is performed to stop the bonus symbol on the activated line of the bonus symbol of the stopped reel, and the process proceeds to S152.

On the other hand, if it is determined in S132 that the bonus winning flag has not been set, the flow advances to S139 to determine whether or not the small role winning flag has been set, and the small role winning flag has been set. If it is determined that the other reel is stopped, it is determined whether or not another reel is stopped. If the other reel is not stopped yet, the process proceeds to S144. In S144, it is determined whether or not the small symbol corresponding to the type of the set small winning flag is within four symbols from the current symbol number. If not, the process proceeds to S146 to immediately stop the reel. To S152. On the other hand, if it is determined in S144 that there is a small combination symbol, the process proceeds to S145, and control is performed to stop the small combination symbol on the activated line, and S1 is performed.
Go to 52. Next, when the other reels are stopped, a determination of YES is made in S140, and the process proceeds to S141.
It is determined whether there is a small symbol on the activated line,
If not, the process proceeds to S147. If there is, the process proceeds to S142, and it is determined whether or not the small symbol that can be stopped on the active line of the stopped small symbol is within four symbols from the current symbol number. If not, the process proceeds to S147. If there is, the process proceeds to S143, and control is performed to stop the small symbol on the activated line of the small symbol of the stopped reel, and then the process proceeds to S152.

If it is determined in S139 that the small winning combination flag is not set, the flow advances to S147. S1
At 47, it is determined whether or not the other two reels are stopped. If not stopped, the process proceeds to S149, where it is determined whether the reel currently stopped is the left reel. If the reel is not a reel, the stop control is immediately performed in S150, and then the process proceeds to S152. If the reel is a left reel, the process proceeds to S151. After the stop control is performed so that the single symbol F does not stop on the activated line, the process proceeds to S152. That is, even if it is determined in S139 that the small win flag is not set, if the single symbol F is stopped on the activated line, the small symbol prize is won. Therefore, the single symbol F is set in S151. It is forcibly shifted and stopped so as not to stop on the active line. At the stage where the other two reels have already stopped, the process proceeds to S14.
7 is determined to be YES, the process proceeds to S148, and after stopping control so that none of the symbols are aligned on the active line, the process proceeds to S152. In this way, if no winnings are made, the first and second stopped reels are:
When the stop operation of the player is detected (S89, S
91, S93) Since the stop is almost instantaneous, in the case of a player who is excellent in the technology of operating the stop buttons 9L, 9C, 9R while timing, the first and second stopped reels are frequently switched. It is possible to stop in the reach state. Then, when the reach sound is generated each time, it becomes noisy and harsh, but in this embodiment,
As shown in S109, since the reach sound is generated only when the big bonus and the bonus winning flag are set, there is no inconvenience to be annoying. If the small win flag is set, a process of clearing the small win flag at the end of one game is performed (S
200). Therefore, despite the fact that the small win flag is set, it is not possible to align small win symbols corresponding to the type of the small win flag in the active line due to the arrangement of reel symbols in the current game. In that case, the small role winning flag is cleared and the small role winning is invalidated, and the small role winning flag is taken over in the next game, and the small role symbol is aligned on the activated line in the next game No control is performed.

The variable display control means for controlling the variable display device is constituted by S63 to S152.

FIG. 16 is a flowchart showing a program of the winning determination processing. First, in S153, it is determined whether or not the bonus game flag is set. If not, the process proceeds to S159, in which it is determined whether or not the big bonus game flag is set, and the flag is not set. In this case, the process proceeds to S163, and it is determined whether or not a winning has been made on the activated line. When there is no winning on the activated line, the process proceeds to S164, where the expected payout number is set to “0”, and thereafter, the process proceeds to the coin payout control shown in FIG. On the other hand, if it is determined in S163 that there is a winning on the activated line, S1 is executed.
Proceeding to 65, the activated line display lamp corresponding to the activated activated line blinks. When a winning occurs on a plurality of activated lines, the activated activated line is blinked. Next, in S166, it is determined whether or not the winning is a big bonus winning. If it is determined that it is not a big bonus prize, the process proceeds to S168, and it is determined whether or not the prize is a bonus prize. If it is determined that the prize is not a bonus prize, it is determined whether or not it is a re-game prize in S170. Is determined. S170
If it is determined that the winning is not a re-game winning, the winning is a small winning combination, so the flow proceeds to S175A, the expected payout number is set to a value corresponding to the small winning, and the flow proceeds to S175B.

If it is determined in S166 that the big bonus has been won, the process proceeds to S167, in which each small role winning determination value is set to the value at the time of the big bonus, the big bonus game counter is set to "30", and the bonus number counter is set. Is set to "3", the big bonus winning flag is cleared, the scheduled payout number is set to "15", the big bonus game flag is set, the game effect lamp is flashed in the first mode, and the big bonus sound is played. A process of generating from a speaker is performed. Since the control for setting each of the small role winning determination values to the value at the time of the big bonus is performed to greatly increase the number of each small role winning determination value, the probability of each small role winning is greatly improved, and the big bonus At the time of the game, control is performed such that small winning symbols are arranged with a high probability. During the big bonus game, a predetermined one of a plurality of types of small role winning flags may be set for each game without making a special determination of the small role winning. On the other hand, S1
If it is determined that the bonus is awarded by 68,
Go to 169, set the bonus game counter to "12", set the JAC winning counter to "8", clear the bonus winning flag, set the expected payout number to "15", and set the bonus game flag Then, a process of blinking the game effect lamp in the second mode and generating a bonus sound from the speaker is performed.

Next, if the bonus game flag is set, the CPU makes a determination of YES through S153 and advances to S154, decrements the bonus game counter by "1", advances to S155, and wins the JAC on the activated line. It is determined whether or not there is, and if not, the expected payout number is set to “0”, and the processing shifts to coin payout control. On the other hand, if there is a JAC winning on the activated line, S156
Then, the payout expected number is set to "15", the JAC winning counter is decremented by "1", and in S157, the activated line display lamp corresponding to the activated activated line is blinked, and thereafter, the flow proceeds to coin payout control.

Next, if the big bonus game flag is set, a YES determination is made in S159 and the process proceeds to S160, in which the big bonus game counter is decremented by "1". A determination is made as to whether or not S163 is satisfied.
, But if there is, the process proceeds to S162. In S162, the bonus game counter is set to “12”, and J
Set the AC winning counter to “8”, set the bonus game flag, set the expected payout number to “8”,
The game effect lamp blinks in the second mode, and a bonus sound is generated from the speaker. As described above, S169 is a process performed when the bonus game is started in the base game other than the big bonus game.
The process 62 is performed when the bonus game is established at the stage when the big bonus game is started.

On the other hand, if it is determined in S170 that the game has been re-winned, the flow advances to S171 to perform processing for storing a random value R (see FIG. 6) of a random counter. A process of turning on or blinking to display a game again and generating a game sound again from the speaker 28 is performed. Next, the process proceeds to S173, where it is determined whether or not a start operation has been performed, and the process waits until there is. Then, when the player operates the start lever 12, the control proceeds to S174, and after the re-game winning flag is cleared, the process proceeds to a reel rotation process shown in FIG. As a result, since the reel rotation control is performed without executing the programs shown in FIGS. 7 and 8, the previously input bet amount is carried over without receiving the additional input of the bet amount. A re-game is performed.

At S175A, after the expected payout amount is set to the value corresponding to the small combination (15, 8, 6, or 3 in FIG. 11), the flow proceeds to S175B to determine whether or not the bonus game flag is set. If it is set, the flow shifts to coin payout processing shown in FIG. on the other hand,
If it is not set, the process proceeds to S175C, and it is determined whether or not the big bonus game flag is set. If it is set, the flow shifts to coin payout control shown in S17. If the big bonus game flag has not been set, the process proceeds to S175E. Note that S175D is a step inserted in the case of another embodiment described later. In S175E, a process is performed in which the value of the number-of-insertions counter is added to the cumulative number of inputs, and the value of the scheduled number of payouts is added to the cumulative number of payouts. Next, S175
Proceeding to F, a process of calculating the cumulative number of payouts / cumulative input is performed, and a process of calculating the value grant status by the slot machine 1 is performed.

Next, the flow proceeds to S175G, and it is determined whether or not the small role determination mode is "high probability". If not, the flow proceeds to S175H, and the value calculated in S175F is 0. It is determined whether the value is less than 4 (lower limit value in normal time). If the value is less than 0.4, the small combination determination mode is set to “high probability” in S175I, and then the process proceeds to S175L. On the other hand, if the calculated value is 0.4 or more, the process directly proceeds to S175L. S1
As a result of the 75G determination, if the small combination determination mode is “high probability”, the process proceeds to S175J, and it is determined whether the value calculated in S175F is equal to or more than 0.5 (the upper limit in the high probability). Is determined. If the value is equal to or greater than 0.5, the flow proceeds to S175K, the small combination determination mode is set to “normal time”, and then the flow proceeds to S175L. On the other hand, S175
If it is determined by J that the calculated value is less than 0.5, the process directly proceeds to S175L. As described above, when the payout rate of the small win is less than 40% when the small win determination mode is normal, the small win determination mode is updated to “high probability”. When the payout rate of the small win reaches 50% when the small win determination mode is “high probability”, control is performed to return the small win determination mode to “normal”.

Next, in S175L, the cumulative number of inputs is “30”.
It is determined whether or not the number is equal to or greater than "0". If not, the flow directly proceeds to the coin payout control shown in FIG. After the process of correcting (rounding up to the decimal point) the value of / 2 is performed, the process shifts to coin payout control. The processing of S175L and S175M is processing for preventing the cumulative input number and the cumulative payout number from becoming too large when the number of games increases.

The method of calculating the coin payout status, that is, the value grant status, is not limited to the embodiment shown in S175F. For example, (cumulative input-cumulative payout) /
The number of games may be calculated. Also, the cumulative number of coins may be used instead of the cumulative number of coins,
Alternatively, it may be calculated using both the cumulative number of payouts and the cumulative number of payouts. Further, an addition / subtraction counter may be provided to add according to the number of coins inserted and subtract according to the number of coins paid out, and the value of the addition / subtraction counter may be used as a calculated value. In the present embodiment, only the small combination occurrence probability is controlled by comparison with the standard value. Therefore, while the payout rate in the base game is kept within a predetermined range, the generation of the big bonus and the regular bonus is controlled by the random value R. It is controlled by the extraction timing and the set value, and even if the setting is high, the number of bonus occurrences is not always large, and even if the setting is low, the number of bonus occurrences is not always small, and the gaming machine can maintain the interest of the game for the player It can be.

In the embodiment shown in FIG. 16, when calculating the payout rate in S175F, the payout rate is calculated based on the number of coins inserted and the number of coins paid out in a normal game excluding the big bonus game and the regular bonus game. But instead, the big bonus game,
The calculation may include the number of coins inserted and the number of coins paid out in the regular bonus game. Also,
The calculation of S175F and the determination of S175H, S175J
It may be performed only when the accumulated number of coins reaches a predetermined value.

Next, another embodiment in which the step of S175D is inserted will be described. In this alternative embodiment, in the base game, the small hand probability control is performed only when three bets are placed. In S175D, the process proceeds to S175E only when the inserted number counter is "3". The probability control of the hand is performed, and if the inserted number counter is not “3”, the process directly proceeds to the coin payout control. In the case of this alternative embodiment, each of the small role winning allowable values C ₁₂ , D ₁₂ , E ₁₂ , and the “High probability” column in the case of the number of inserted coins “1” and “2” in FIG. _{F 12, C 22, D 22} , E 22, F 22 becomes unnecessary. In steps S175E to S175M, it is calculated based on at least one of the cumulative value of the input number input by the bet amount input means, the cumulative value of the valuable value provided by the value providing means, and the cumulative value of the number of times the valuable value is provided. Probability control means is configured to compare the value provision status with a predetermined standard value and to control the probability that the display result of the variable display device has a specific display mode based on the comparison result.

FIG. 17 is a flowchart showing a coin payout control program. First, in S176, it is determined whether or not the number of payouts has reached the expected number of payouts. If not, the process proceeds to S177, and it is determined whether or not the game mode is the credit game mode. Proceeds to S180, pays out one coin, increases the payout number by "1", and returns to S176. On the other hand, if it is in the credit game mode, the process proceeds to S178, and it is determined whether or not the credit counter has reached its upper limit value of "50". If so, the process proceeds to S180 to pay out coins. If not, that is, if there is still room for storing the credit counter, the flow advances to S179 to increment the credit counter by "1", and accordingly, the payout number is incremented by "1", and then to S176. Return to This S177
Steps S180 to S180 are repeatedly executed until the number of payouts reaches the expected number of payouts, and each time coins are paid out or added to the credit counter, the process proceeds to S181 when the number of payouts reaches the expected number of payouts. .

In S181, it is determined whether or not the bonus game flag has been set. If the bonus game flag has not been set, the process proceeds to S182,
It is determined whether or not the big bonus game flag is set. If the big bonus game flag is not set, the process proceeds to S200, the JAC winning flag is cleared, the small role winning flag is cleared, and Is updated to the value of the insertion number counter, the insertion number counter is cleared, and the process returns to the game start processing shown in FIG. 7B. On the other hand, if the bonus game flag has been set, the process proceeds to S185, and it is determined whether or not the JAC winning counter has become “0”. If so, the bonus game counter has been cleared in S186. , S18
By means of 8, the JAC winning counter is cleared and the bonus game flag is cleared. On the other hand, if the JAC winning counter is not "0", the process proceeds to S187, and it is determined whether or not the bonus game counter is "0".
If it is "0", the process proceeds to S188. If it is not "0", the process proceeds to S200, where the JAC winning flag is cleared.
The small win winning flag is cleared, and the process returns to the game start processing shown in FIG. As described above, when the bonus game counter becomes “0” or when the JAC winning counter becomes “0”, the bonus game flag is cleared and the bonus game ends.

Next, in S189, it is determined whether or not the big bonus game flag is set. If not, the process goes to S190 to turn off the game effect lamp 24, and the process proceeds to S200. On the other hand, when the big bonus game flag is set, the process proceeds to S191, and the bonus number counter is set to “1”.
A process of decrementing is performed, and it is determined in S192 whether or not the bonus number counter has become “0”. When the bonus number counter is not "0", the process proceeds to S193, in which the game effect lamp is caused to blink in the first mode, and the big bonus sound is generated from the speaker 28, and the process proceeds to S200. On the other hand, if the bonus number counter is "0", the process proceeds to S194, and after clearing the big bonus game counter, the process proceeds to S1.
Go to 95.

On the other hand, if the bonus game flag has not been set and the big bonus game flag has been set, the flow advances to S183 to determine whether or not the big bonus game counter is "0".
If it is not "0", the process proceeds to S200, but if it is "0", the process proceeds to S184, where a process of clearing the bonus number counter is performed, and the process proceeds to S195A. In S195A, the big bonus game flag is cleared to end the big bonus game, the small role determination mode is set to "normal time", the cumulative insertion number is set to "100", the cumulative payout number is set to "50", and the gaming effect is set. A process for turning off the lamp is performed. In other words, the big bonus game ends when the big bonus game counter becomes “0” or when the bonus number counter becomes “0”. Since the game becomes a normal game thereafter, the small role winning determination mode Is returned to the “normal time”, and control is performed to return the cumulative number of inputs and the cumulative number of payouts to the initial values (see S14A).

Then, the process proceeds to S195B, in which a process of storing the current random value R is performed, and in S195C, a process of performing a predetermined operation using the stored value is performed. This predetermined operation is, for example, subtracting, adding, multiplying, or dividing a predetermined numerical value to a stored random value R, squaring or squaring the random value R, and further, This is an operation such as calculating the answer by substituting the value R into a predetermined function. Next, S195D
Then, a process of comparing the calculation result with the probability variation winning allowable value is performed. The probability variation winning allowable value is an allowable value that can improve the big bonus game occurrence probability. Two types of the probability fluctuation winning allowable value are defined: a probability fluctuation twice winning allowable value for generating the probability fluctuation state twice, and a probability fluctuation once winning allowable value for generating the probability changing state only once. . By S195E, if the calculation result is within the range of the probability variation twice winning allowable value, S
Proceeding to 195F, a process of setting the scheduled stop symbol of the number-of-games / variable display 25 to “77” is performed, and S19 is performed.
Proceed to 5J. On the other hand, if the calculation result is within the range of the one-time winning variation allowable value, the determination of NO is made in S195E, and the determination of YES is made in S195G.
Proceeding to 195H, a process of setting the scheduled stop symbol of the number-of-games / variable display 25 to "33" is performed, and S195
Go to J. On the other hand, if the calculation result is not within the range of the probability fluctuation twice winning allowable value and is not within the range of the probability fluctuation once winning allowable value, the process proceeds to S195I, and the scheduled stop symbol of the game number / variable display 25 is changed. A process of setting a missing stop symbol is performed.

Next, in S195J, a timer for variably displaying the number-of-games / variable display 25 is set, and the variable display is controlled to start. Next, the process proceeds to S195K, where it is determined whether or not the set timer has expired. The process waits until the timer expires, and continues to variably display the game count / variable display 25. Then, when the timer has expired, the flow proceeds to S195L, where the number of games / variable display 25
Is controlled so as to achieve the stop symbol set in S195F, 195H or 195I. Next, the process proceeds to S195M, and it is determined whether or not a special game state in which the stop symbol is “77” has occurred.
If so, the process proceeds to S195N, where a process of setting the probability variation counter to “2” is performed, and the process proceeds to S195Q.
On the other hand, when the special game state in which the stop symbol is "33" has occurred, the determination of YES is made in S195O, the process proceeds to S195P, the process of setting the probability variation counter to "1" is performed, and the process of S195Q is performed. Proceed to. If the stop symbol is a lost symbol, S195N, S195
The processing of P is not performed. Next, the process proceeds to S195Q, where it is determined whether or not the value of the probability variation counter is “0”. If the value is “0”, the process proceeds to S196. After blinking the lamp in the third mode and displaying to the player that the probability of occurrence of the big bonus game is improved is S <b> 19.
Proceed to 6. Note that the step of S195S may be inserted after this S195R. This S195S is a process for setting the small combination determination mode to “high probability”. As a result, if the probability variation counter is not “0”, the small role determination mode is set to “high probability”. By performing the processing of S175A and S195S, when the probability fluctuates, the big bonus winning probability is improved and the small role payout rate at the time of “high probability” becomes 100% (so-called equal return). The game can be played without reducing the number of coins until the player is elected. In this embodiment, the variable display for randomly selecting whether or not to enter the probability fluctuation state is configured by the game number / variable display 25 for displaying the number of games, but a variable display dedicated to the lottery may be provided. Good. Also, reels 6L, 6C,
The lottery display may be performed using 6R. Further, the number of times of probability change is not limited to two types, and may be one type or three or more types. Alternatively, instead of or in addition to changing the number of times of the probability change, the winning probability of the big bonus at the time of the probability change may be changed. In addition, S195N and S195
In P, the process of setting the probability variation counter to “2” and “1” is performed, but instead, it may be set to +2 and +1 each time these steps are executed. When the probability variation counter is not “0”, the winning may be invalidated, or the lottery may not be performed.

Further, the lottery timing for determining whether or not to perform the probability change is not limited to the embodiment. For example, when the big bonus is won, when the big bonus occurs, the next game after the big bonus game ends, when a specific small role occurs, when the game is replayed, when the bonus is won, when the bonus occurs, the next game after the bonus game ends, etc. It may be time. By the above-mentioned S176 to S200, the coin hopper 37, the coin payout motor 38, and the payout coin sensor 39, a value that gives a predetermined value when the display result of the variable display device has a predetermined specific display mode. An application unit is configured. Further, S195B to S195B
195P, S77A, S77B, S67, FIG.
According to the table data shown in (a), (b), and FIGS. 11 (a), (b), when the gaming state of the gaming machine has reached a predetermined special gaming state, the variable display device Probability variation control means for varying the probability that the display result is the specific display mode is configured.

Next, the flow proceeds to S196, where it is determined whether or not game over is set. If the reset switch 4 is turned on when the power is turned on, the game is not over as described above (S3).
When the reset switch 4 is turned OFF, the game is over as described above (see S2). In S196, it is determined whether or not the game is over. Has S2
00, and thereafter returns to the game start shown in FIG. 7B, and the game start process is started. On the other hand, when it is determined that the game is over, the process proceeds to S197, and a process of displaying the code “OF” on the number-of-payouts display 27 and generating the game over sound from the speaker 28 is performed. As a result, the game of the slot machine is over (a hit state). The process advances to S198 to determine whether or not there is a reset operation.
The process at 97 is continued. Then, if a staff at the game arcade inserts a predetermined key into the reset keyhole 3b and operates the reset switch 4, a YES determination is made in S198, the process proceeds to S199, and the "OF" code display is cleared. After the game over sound is stopped, the process proceeds to S200.
With this configuration, according to the mode of operation of the game arcade, in the game arcade where the prize exchange is performed each time the slot machine reaches the knocked down state, the hitting means functions as the hitting selection means. On the other hand, if the gaming machine adopts a so-called non-quantitative method in which the game is continued without prize exchange even if the slot machine reaches the stop state, the stop selection means May be selected so that the hitting means does not function.

As another method of controlling the stop of the slot machine in accordance with the business mode of the game arcade, there is the following method.

After the processing of S195 shown in FIG. 17, for example, an automatic reset timer is set, and then a processing of displaying a code "OF" and generating a game over sound is performed. A determination step is provided. If it is determined that the game is not over, the process proceeds to a step of determining whether or not the automatic reset timer has expired. If the timer has not expired, the code “OF” is displayed again and The process returns to the step of generating the game over sound. Then, when the timer for automatic reset has expired, a process of clearing the code display and stopping the game over sound is executed, and then the process returns to S200 shown in FIG. On the other hand, when it is determined that the game is over in the step of determining whether the game is over, the process proceeds to a step of determining whether a reset operation is performed. If it is determined that there is no reset operation, the code "OF" is displayed and the process returns to the process of generating a game over sound. When it is determined that the reset operation is performed, the process proceeds to the process of clearing the code display and stopping the game over sound, and then proceeds to S200 in FIG.

In other words, if the game has not been set in S1 to S3, the system waits until the automatic reset timer expires, and displays a code indicating that the game is over automatically at the end of the timer. Clear the game over sound and return to the game start process. If the game over is set, the code indicating the game over is displayed until the reset switch 4 is operated, and the game over sound is displayed. The stopping state generated from the speaker is maintained. The step of determining whether or not there is the reset operation and the processing step of clearing the code display and stopping the game over sound constitute a manual stop release means for releasing the stop by manual operation. I have.
In addition, S1 to S3 constitute a striking release mode selecting means for selecting one of striking cancellation by the automatic striking releasing means and striking cancellation by the manual striking releasing means. According to this alternative embodiment, when the game is in the no-game-over mode, once the big bonus game is over, the game is temporarily over (stop state), and the game-over is automatically performed after a predetermined time has elapsed. Since the game is released, the game is not played for a predetermined time during which the game is over. As a result, when the profit management information such as inserted coins and the disadvantage information such as premium coins are totaled by the hall management computer, a game over state in which the game is not performed is separated from a game over release to the next game over or a big game over. It is also possible to perform the totalization of information in a unit from the start of the bonus game to the game over.

Although the lending of coins is not performed during the period from the start of reel rotation to the end of payout of coins, lending may be performed at all times. Further, the present invention may be a slot machine of a type in which a game is played using a pachinko ball instead of a coin. In this case, the bet amount input means detects the number of pachinko balls inserted by the player as the bet amount. Further, a slot machine in which a game is played by inserting a recording medium such as a card and using a value owned by the player specified by the recording information of the recording medium may be used. In this case, the operation detecting means for detecting an operation of the player for using a part of the value of the player as the bet amount becomes the bet number input means. Further, the variable display device may automatically stop when a predetermined time elapses without the stop button, or the variable display device may be variably started by inputting a bet amount without the start lever. S176 to S200,
The coin hopper 37, the coin payout motor 38, and the payout coin sensor 39 constitute a value giving means for giving a predetermined value when the display result of the variable display device becomes a predetermined specific display mode. I have. Instead of paying out coins as a prize, the value providing means may pay out pachinko balls or add a score and pay out a recording medium on which the score is recorded at the end of the game. In addition, the variable display device is not limited to a rotating reel type, but may be a device that variably displays a pattern by an electric display device including a CRT, a liquid crystal, an LED, electroluminescence, or the like, or a plurality of disks on which the pattern is drawn. Any type of variable display device may be used, such as one that rotates and variably displays, one in which a belt on which a pattern is drawn moves, or a so-called leaf type. Further, the number of variable display units is not limited to three.

The bet number for inputting within a predetermined range a bet number, which is a number corresponding to the value of the value owned by the player who bets on the game result of the one game, by the coin slot 18 or the credit operation button 14. An input means is configured.

The symbols shown in FIG. 3 constitute a plurality of types of identification information. The symbols "AAA" and "BBB" constitute predetermined special game state identification information. Further, in addition to the big bonus game and the bonus game, the display result of generating the small combination constitutes a predetermined specific display mode of the display result of the variable display device.

The control section 45 derives and displays the special game state identification information on the variable display device, thereby forming a game control means capable of controlling a special game state that is advantageous to the player.

In the above embodiment, when the value of the probability variation counter is not “0” and the probability of occurrence of the big bonus game is improved, the number of coins inserted is limited to three, that is, the case of three bets. With this configuration, the probability variation control unit sets the bet number input by the bet number input unit to
It is disclosed that the probability change is performed only when the maximum bet number is within the predetermined range that can be input.

By performing the processing of S175A and S195S, if the probability fluctuates, the big bonus winning probability is improved, and the small role payout rate at the time of “high probability” is 100% (so-called equal return). Accordingly, it is disclosed that during the probability fluctuation by the probability fluctuation control means, the payout rate calculated by the number of valuable values provided by the value providing means with respect to the bet amount by the bet number input means is maintained at almost 100%. Have been.

Instead of or in addition to changing the number of times of the probability change, the description that the probability of winning the big bonus at the time of the probability change may be changed may be made.
It is disclosed that the special game state identification information is derived and displayed by the variable display device while the probability change is being performed, so that there are a plurality of types of the probability of being in the special game state. I have.

Next, another embodiment of the present invention will be described. (1) As a special game state in which the probability change start condition is satisfied, when the calculation result in S66 is, for example, a part or all of the values within the range of the big bonus winning allowable value, the regular bonus winning allowable When it becomes a part or all of the value within the range of the value, when it becomes a part or all of the value within the range of each small role winning allowable value, or part or all of the range of the re-game winning allowable value May occur when the value becomes a part of the value within the range of the deviation.

(2) The special game state may be generated when the big bonus game and the regular bonus game end in a specific pattern. For example, a case where a bonus game occurs at a specific game number in the big bonus game or a case where a JAC winning occurs at a specific game number in the bonus game can be considered. A special game state may be generated when the combination of the number of games when the bonus game occurs and the number of games when the JAC winning occurs becomes a specific pattern.

(3) A special game state may be generated when the variable display device including the reels 6L, 6C, and 6R has a display result determined to start a probability change. For example, when a special symbol is provided in the symbol array of the reel and the symbol is stopped on an effective line (hit line), or a part of a symbol combination (for example, “AAB”) which is lost is determined as a start of probability fluctuation. It is conceivable that a special game state is set when the combination of symbols is stopped on an active line (hit line) or the like.

(4) A special game state may be set when a big bonus game does not occur for a predetermined period (a predetermined number of games or a predetermined cumulative number of coins). For example, when a big bonus game and a regular bonus game do not occur for a predetermined period, when a big bonus game does not occur for a predetermined period, or when a regular bonus game occurs a predetermined number of times without a big bonus game for a predetermined period, a special game state is set. You may make it become.

(5) A special gaming state may be set when the difference between the gaming machines and the payout rate reach a predetermined value.
In this case, it is conceivable that the difference number and the payout rate are counted from the time of opening the game hall, from the end of the previous big bonus game, or from the time of changing the setting of the probability.

(6) In performing the probability variation control, the number of symbol combinations of the variable display device in which the big bonus game occurs may be increased. With this configuration, when the actual occurrence probability is improved, the display occurrence probability of the variable display device is also improved.

(7) When the state of probability change occurs,
Only the big bonus game occurrence probability, the regular bonus game occurrence probability only, each small role occurrence probability only,
Only the re-game occurrence probability may be fluctuated. Alternatively, the probability variation control may be performed by selecting two or more of the above items. When the probability variation is performed by selecting the two or more objects, the trigger of the probability variation may be the same for each probability variation object or may be different. As mentioned above,
According to the description that the occurrence probability of the re-game is fluctuated, identification information for the re-game that can execute the game without inputting the bet amount by the player is derived and displayed in the predetermined display mode. Is disclosed.

(8) As a condition for terminating the probability fluctuation state, the condition may be terminated when the same condition as the start condition in (1) is satisfied. In this case, the specific value with which the calculation result of S66 is compared may be the same value as the start condition of (1) or may be a different value.

(9) The probability change may be terminated when the same condition as the probability change start condition shown in (2) is satisfied. In this case, the number of games and the specific pattern shown in the above (2) may be the same as or different from the probability variation start condition. Further, the probability variation state may be ended when a bonus game does not occur at a specific game number during the big bonus game or when a JAC winning does not occur at a specific game number during the bonus game. Furthermore, the probability variation state may be ended when the combination of the number of games in which the bonus game has occurred and the number of games in which the JAC winning has occurred does not form a specific pattern.

(10) The probability variation state may be ended when the variable display device from the reels 6L, 6C, 6R has a display result determined to end the probability variation. Specifically, a special symbol is provided in the symbol array of the reel, and when the symbol is stopped on an effective line, or a part of a combination that becomes a symbol of loss is determined as a display result that ends probability fluctuation, It is conceivable that the symbol combination stops on the activated line. In these cases, some of the special symbols and combinations may be the same as or different from the symbols and combinations determined by the start condition of (3). Furthermore, the probability fluctuation state may be terminated when the display result in which a regular bonus occurs or the display result in which a specific small combination occurs.

(11) The probability fluctuation state may be ended when a predetermined period has elapsed after the start of the probability fluctuation. According to this description, the probability variation control means allows the display result of the variable display device to be in the predetermined display mode when the gaming state of the gaming machine is in a predetermined special gaming state. Performing a probability variation in which the probability that is determined, and the probability variation control means,
It is disclosed that the probability change ends when a predetermined period elapses. For example, after the probability variation state starts, the game may be terminated when a predetermined number of games has been reached or when a predetermined number of coins have been inserted. According to this description, it is disclosed that the predetermined period is a period until the execution of a predetermined number of games is completed. Or,
The probability variation state may be terminated when the role subject to the probability variation control shown in (7) occurs a predetermined number of times. Further, the probability fluctuation state may be ended when the earlier condition of the above or any of the above is satisfied. According to this description, the predetermined period is the earlier of the period until the execution of the predetermined number of games is completed or the period until the prize is generated a predetermined number of times in the predetermined display mode performing the probability change. It is disclosed that this is a period until elapses.

(12) The probability variation state may be ended when the difference number of the gaming machines and the payout rate reach predetermined values. It is conceivable that the difference number and the payout rate are counted from the opening of the game hall, from the change of the probability setting, or from the start of the probability change.

According to the first aspect, the probability variation ends when a predetermined period elapses while the probability variation is being performed. When the predetermined period elapses, the probability change ends regardless of the presence or absence of the predetermined display mode, so that the game is changed and the interest of the game is improved.

According to the second aspect, in addition to the effect of the first aspect, the probability fluctuation ends when the period until the execution of the predetermined number of games ends, so that the period until the end of the probability fluctuation is determined by the player. This has the effect of being easy to understand.

According to the third aspect, in addition to the effect of the second aspect, the execution of a predetermined number of games is completed, or a predetermined number of prizes in the predetermined display mode in which the probability is fluctuating are generated or early. If this is true, the probability change ends. Probability fluctuation does not take place over a long period of time, the value can be assigned to an appropriate level, and an appropriate ejaculation can be maintained.

According to the fourth aspect, in addition to the effects of the first to third aspects, it is not necessary to prepare a plurality of probability variation tables according to the probability variation according to various bet numbers, and the storage area required for control is not required. Can be saved.

According to the fifth aspect, in addition to the effects of the first to fourth aspects, the possibility that the value owned by the player is reduced by the occurrence of the next special game state during the probability fluctuation is extremely small. , The interest of the game can be improved.

Regarding the sixth aspect, in addition to the effects of the first to fifth aspects, a change occurs in the game at the time of the probability fluctuation, and the interest of the game can be further improved.

According to the seventh aspect, in addition to the effects of the first to sixth aspects, there is a possibility that the winning probability of the re-game will fluctuate during the probability fluctuation, and the value owned by the player will decrease during the probability fluctuation. Can be further reduced, and the interest of the game can be improved.
