Recent pachinko machines have a jackpot probability within a certain range in order to comply with the legally specified ball-off rate. Thereby, gambling is moderately suppressed, and the soundness of the game is improved.
However, even if the jackpot occurrence probability is set within a certain range, if the jackpot occurrence probability is designed to be low and there is a high possibility that the jackpot will be continuously generated due to probability change or the like, there is a possibility that the frequency of jackpot occurrence will be biased. In this case, it is conceivable that the actual launch test may or may not conform to the legal launch rate.
In such a case, there is a possibility that problems such as disadvantage to the player and excessive profit to the player may occur.

The present invention was made to make the gaming machine more sound, and the gaming machine according to claim 1 is a special symbol start in which a special symbol starts to fluctuate as a random number is acquired by passing a game ball. A special success / failure determination means for determining whether or not a special hit is made based on the acquired random number, and a special electric accessory that can be opened and closed is determined in advance by the determination result of the special success / failure determination means. A first special winning gaming means that opens and closes a predetermined number of times, and a second special winning gaming means that opens and closes the special electric accessory less than the predetermined number of times according to a determination result of the special success / failure determination means, In a gaming machine in which the probability of generating a special game by a special hit gaming means is 1 / N, and the probability of generating a special game by the second special hit gaming means is 1 / M,
If the number of times that the second special winning game means is opened and closed is a natural number that is less than 1/4 of the predetermined number, the probability of generating a special game is 1 / N,
When the number of times of opening and closing the special electric accessory by the second special hit gaming means is a natural number that is 1/4 or more of the predetermined number of times and less than the predetermined number of times, the probability of generating a special game is 1 / N + 1 / M,
It is characterized by the design of the launch rate.
The predetermined number of times is preferably 14 to 16 times.

The gaming machine according to claim 2 acquires a random number by passing a game ball and determines whether or not a special symbol is started based on the special symbol starting port where the special symbol starts to fluctuate and the acquired random number. According to the determination result of the special success / failure determination means, the first special hit game means for opening the special electric accessory that can be opened and closed by a predetermined time based on the determination result of the special success / failure determination means, and the determination result of the special success / failure determination means Second special hit gaming means for opening and closing the special electric accessory for a time shorter than the time, wherein the probability of generating a special game by the first special hit gaming means is 1 / N, and the second special hit gaming means In a gaming machine with a 1 / M probability of generating a special game by
If the time for opening the special electric accessory by the second special hit gaming means is less than ¼ of the predetermined time, the probability of generating a special game is 1 / N,
When the time for opening the special electric accessory by the second special hit gaming means is 1/4 or more of the predetermined time and less than the predetermined time, the probability of generating a special game is 1 / N + 1 / M,
It is characterized by the design of the launch rate.
The predetermined time is preferably 20 seconds to 30 seconds, and a configuration in which the game is closed when ten game balls are awarded to the opened electric game object is preferable.

According to the first aspect of the present invention, when the number of times of opening and closing the special electric accessory by the second special hit gaming means is a natural number less than 1/4 of the predetermined number, the probability of generating a special game is 1 / Since the pitching rate is designed as N, the probability 1 / N cannot be made extremely small. As a result, the number of times that the special game is continuously generated due to the probability change cannot be increased, so that the frequency of generating the special game is less biased. If the probability is not 1 / N small and a special game is generated continuously, it will not be possible to comply with the legal pitch rate.
Even if the probability of generating a special game is set to 1 / N, the number of times that the special electric combination is opened and closed by the second special hit game means is a natural number less than 1/4 of the predetermined number. 2 The number of prize balls won by special game means is small. For this reason, there is little influence on an actual pitching rate.

According to the second aspect of the present invention, when the time for opening the special electric accessory by the second special winning game means is less than ¼ of the predetermined time, the probability of generating the special game is set to 1 / N, and the ball-out rate is obtained. Since it is designed, the probability 1 / N cannot be set to a very small value. As a result, the number of times that the special game is continuously generated due to the probability change cannot be increased, so that the frequency of generating the special game is less biased. If the probability is not 1 / N small and a special game is generated continuously, it will not be possible to comply with the legal pitch rate.
Also, even if the probability of launching is set with 1 / N as the probability of generating a special game, the time for opening the special electric accessory by the second special hit game means is less than 1/4 of the predetermined time, so the second special The number of winning balls won by winning game means is small. For this reason, there is little influence on an actual pitching rate.

The opening and closing of the start port 12 is controlled. In addition, the ordinary electric utility means an ordinary electric accessory (also referred to as an electric tulip).
In addition to the above, the output signal from the main control device 80 is a test signal terminal, and management signals such as symbol variation and jackpot are output to the external connection terminal board 78 and sent to the hall main computer.

The main control device 80 and the payout control device 81 can perform bidirectional communication.
The payout control device 81 operates the payout motor 20 in accordance with a command sent from the main control device 80 and pays out a prize ball. In the configuration of FIG. 4, the payout control device 81 is configured to control the payout motor 20 via the back wiring relay terminal plate 75 and the payout relay terminal plate 76. In the present embodiment, the detection signal of the payout switch 21 for counting game balls to be paid out as winning balls is input to the payout control device 81, and the payout control device 81 counts the winning balls. . In addition, it is also conceivable to use a configuration in which the detection signal of the payout switch 21 is input to the main control device 80 and the payout control device 81 and both the main control device 80 and the payout control device 81 count the prize balls.

The payout control device 81 is configured to receive signals from the full switch 22 and the ball-out switch 23, and when the signal indicating that the lower plate 63 is full is input from the full switch 22 and from the ball-out switch 23. When a signal indicating that there are few or no game balls is input to the ball tank 71, the payout motor 20 is stopped, and the payout operation of the prize ball is stopped. Note that the full switch 22 and the ball break switch 23 are also configured to continue outputting signals until the state is cleared, and the payout control device 81 causes the payout motor 20 to stop being output. Restart the drive.
In addition, the payout control device 81 communicates with the CR unit 56 (also referred to as a game ball lending device) via the CR unit terminal plate 24 (also referred to as a game ball lending device connection terminal plate), thereby causing the payout motor 20 to communicate. Operate and discharge the rental balls. The paid-out lending ball is detected by the payout switch 21, and the detection signal is input to the payout control device 81. The CR unit terminal board 24 is also connected to the settlement display device 25 so as to be capable of two-way communication. The settlement display device 25 has a ball switch 57 for requesting a game ball to be rented, and a request for payment. A return switch 58 is connected.

The payout control device 81 transmits information relating to the winning ball, information indicating the open / closed state of the frame (inner frame 70, front frame 52), etc. to the hall computer 87 via the external connection terminal board 78, and also to the launch control device 84. In response to this, a fire stop signal is transmitted.
The launch control device 84 controls the launch motor 30 to launch the game ball into the game area 3.
In addition to the payout control device 81, a rotation amount signal from the launch handle 64, a touch signal from the touch switch 28, and a launch stop switch signal from the launch stop switch 29 are input to the launch control device 84.

If the touch signal is not input to the launch control device 84, the game ball cannot be fired, and if the launch stop switch signal is input, the game ball can be launched even if the player touches the launch handle 64. There is no such thing.

The sub-integrated control device 83 receives data and commands transmitted from the main control device 80, distributes them to data for effect display control, sound control, and lamp control, and so on. Is transmitted to the production symbol control device 82, and the sound control and lamp control are distributed to each control part (function unit as a sound control device and a lamp control device) included in itself. Then, the function unit as the sound control device controls the sound output from the speaker 66 by operating the sound LSI based on the data for sound control, and the function unit as the lamp control device converts the data for the lamp control. Based on the operation of the lamp driver, various LEDs and various lamps are controlled. As for audio output, the volume can be adjusted by the volume adjustment switch 83a.
In addition, an effect button 67 is connected to the sub integrated control device 83, and when the player operates the effect button 67, a signal is input to the sub integrated control device 83.

Bi-directional communication is possible between the sub integrated control device 83 and the production symbol control device 82. Of course, the structure of the one-way communication from the sub integrated control apparatus 83 to the effect design control apparatus 82 may be sufficient.
The effect symbol control device 82 displays the effect symbol display based on the data and commands received from the sub integrated control device 83 (both those transmitted from the main control device 80 and those generated by the sub integrated control device 83). The device 6 is controlled to display an effect image such as a pseudo symbol on the screen 6a.

Next, the operation of the power-on process of the main control CPU of the main controller 80 will be described in detail.
As shown in FIG. 5, after a security check (not shown) is completed, the main control CPU first executes a power-on process.
Here, after the RAM initial setting process (S1) is performed, it is determined whether or not the RAM clear signal is input, that is, whether or not to erase the RAM (S2). If the determination is affirmative (S2: yes), the RAM is erased. (S6) is performed, and an initial screen designation command is transmitted to the sub integrated control device 83 (S8).

If the determination is negative (S2: no), it is determined whether or not the RAM guarantee value is 1 (S3). If the RAM guarantee value is not 1 (S3: no), the RAM is erased (S6), the initial screen designation command is transmitted (S8), and if the RAM guarantee value is 1 (S3: yes), the SUM value creation process (S4) is performed. It is determined whether or not the SUM value is 0 (S5).
If the SUM value is not 0 (S5: no), the RAM is erased (S6), and the initial screen designation command is transmitted (S8).
If the SUM value is 0 (S5: yes), a power recovery process (S7) is performed to return to the gaming state before the power interruption based on the data stored in the RAM. When the power is restored by the power restoration process, the standby screen is displayed without transmitting the initial screen designation command.
In the present embodiment, the power-on process is terminated by executing S8 or S7, and the remaining process is started.

Subsequently, the description of the residual process is started.
Here, interrupts are prohibited (S9), and it is determined whether the NMI flag is 0 (S10).
If the NMI flag is 0 (S10: yes), the initial value random number update process 1 (S11), the initial value random number update process 2 (S12), and the initial value random number update process 3 (S13) are executed to release the interrupt inhibition. (S14). In this embodiment, the initial value random number 1 is a process for updating the initial value of the jackpot symbol determination random number acquired by the first start port switch 11a, and the initial value random number 2 is set by the second start port switch 12a. The initial value random number 3 is a process for updating the initial value of the winning symbol determination random number acquired by the normal symbol operation switch 17a.
If there is an INT interrupt during the remaining process, the interrupt prohibition is canceled (S14), and then the process jumps to the interrupt (INT) process shown in FIG.

  In this process, various random numbers used for the special symbol success / failure determination are updated (S21), the timer count is updated (S22), and a game ball detection signal or a frame from a detection switch installed at a winning opening or the like is updated. Input processing of signals and the like from switches provided in the apparatus (S23), special symbol game processing (S24) relating to the execution of the success / failure notification and jackpot game, normal symbol success / failure determination and normal electric accessory (second start Mouth) Normal symbol game processing (S25) related to the control of 12, production effect command display processing to the sub-integrated device 83 that controls display of effect images, electrical decoration, audio output, etc. (S26), special symbol display device 9 Data output processing (S27) is performed for display control and opening / closing control of the variable winning opening (ordinary electric accessory 12, large winning opening 14).

Then, the interrupt count counter is incremented by 1 (S28), and it is determined whether or not the interrupt count exceeds a predetermined number (S29).
Since the INT interrupt is performed periodically (every 2 ms or every 4 ms) by the timer, counting the number of interrupts is the same as measuring the elapsed time after the power-on processing (see FIG. 5) is performed. It will be.
If the number of interruptions exceeds the predetermined number (S29: yes), that is, "the time measurement by the timer means has passed the predetermined time".
The predetermined time (predetermined number of times) is set to be equal to or longer than a time obtained by subtracting the time required for the security check of the main control CPU from the time required for the security check of the prize ball control CPU 31a.
If the interrupt count exceeds the predetermined count (S29: yes), a prize ball command is transmitted to the payout control device 81 (S30).

The prize ball command is a command generated based on a game ball detection signal (see S23) from a detection switch installed at a winning opening, and has a data configuration that can specify the number of payouts (number of prize balls). Yes.
When the prize ball command is sent from the main controller 80, the prize ball control CPU of the payout control device 81 drives the payout motor 20 via the payout relay terminal board 76, and the number specified by the prize ball command. The prize ball is paid out.

When the interrupt count does not exceed the predetermined count (S29: no), the prize ball command generated as described above is stored in, for example, the RAM (S31).
Here, instead of storing the prize ball command, the number of prize balls may be stored, or the number of prize balls for a plurality of winning prizes may be added and stored.
When S30 or S31 is executed, the process returns from the interrupt (INT) process to the remaining process.

On the other hand, the power failure detection circuit 110 provided in the power supply device 85 (see FIG. 8) detects a power failure and outputs a power failure detection signal 111. When this signal is input to the main controller 80, a reset signal is sent to the main control CPU. (NMI signal) 112 is provided. In this embodiment, NMI (non-maskable interrupt) is used as the reset signal, and hence the reset signal is hereinafter referred to as an NMI signal.
When there is an NMI signal 112, the main control CPU immediately interrupts the current program regardless of the residual process and the main process, and jumps to the interrupt (NMI) process shown in FIG. Forcible interrupt processing is performed by jumping to interrupt (NMI) processing without shifting to the next step.
In this interrupt (NMI) process, the address of the current program is stored in the register (S35), the NMI flag is set to 1 (S36), and the process is restarted from the address stored in the register (S37).

If S9 is executed in the remaining process after the restart of this process, the NMI flag is 1 (S10: no), so the process proceeds to the backup process to create a SUM value (S15) and set the RAM guaranteed value to 1. In this manner (S16), the RAM write protection process (S17) prohibits the writing of the RAM.
If power is restored after backup processing is performed in this way, power-on processing is performed. However, since the RAM guarantee value is 1 here (S3: yes), the above-described S4 and S5 are executed, and Since the SUM value is not 0 (S5: yes), a power recovery process (S7) is performed.

If there is an INT interrupt during the remaining process executed after the power-on process, the interrupt prohibition is canceled (S14) and the process jumps to the interrupt (INT) process and performs this process. When there are winnings at various winning openings, the payout cannot be made immediately, but the main controller 80 can detect and store the winning.
With respect to the detected winning, since the winning ball command is transmitted from the main control device 80 to the paying control device 81 after the time required for the winning ball control CPU of the payout control device 81 to elapse, the winning ball command is paid out. The control device 81 is not missed.
Therefore, the player does not suffer the disadvantage that the winning ball is not paid out even though the player has won.

FIG. 8 is a block diagram showing power supply of the power supply device 85.
As shown in FIG. 8, the power supply device 85 includes a power supply circuit 113, a power failure detection circuit 110, a backup power supply circuit 114, a power reception circuit 116, a power switch 117, and a RAM clear switch 115.
The power supply circuit 113 generates and supplies operating power for each control device, actuator, and the like based on the main power supply AC24V supplied via the power receiving circuit 116. In addition, a power switch 117 is connected to the power receiving circuit 116 to switch the supply of the main power AC 24V from the power receiving circuit 116 to the power circuit 113 to conduction / non-conduction.

The backup power supply circuit 114 charges the DC5V generated by the power supply circuit 113 and supplies it as a backup power supply (DC5V) to the backup target. The power failure detection circuit 110 outputs a power failure detection signal 111 and a reset signal (NMI signal) 112 to the main control device 80 and the payout control device 81 when the voltage (24V) of the main power supply drops below a predetermined voltage. Note that when the voltage of the main power source rises above a predetermined voltage, the output of both the power failure detection signal 111 and the reset signal 112 is stopped.
In the present embodiment, the power failure detection signal 111 and the reset signal 112 are transmitted to the main control device 80 and the payout control device 81, but this configuration is not necessarily required. The main controller 80 may transmit only to the main controller 80, and the main controller 80 may transmit a power failure command to the payout controller 81, or vice versa.

  The RAM clear switch 115 outputs a RAM clear switch signal according to the operation. Note that the RAM clear switch signal generation circuit for outputting the RAM clear switch signal by the operation of the RAM clear switch 115 is not necessarily provided in the power supply device 85, and either the main control device 80 or the payout control device 81. It is also possible to provide the main control device 80 and the payout control device 81, respectively. In that case, the RAM can be cleared only for the main control device, or only the payout control device 81 can be cleared.

In the start winning confirmation process shown in FIG. 9, the main control device 80 places a game ball on the first start port 11 or the second start port 12 based on the detection signal of the first start port switch 11a or the second start port switch 12a. It is determined whether or not the ball has entered (S40). In this embodiment, since the game configuration has the special symbol 1 and the special symbol 2, each of them has the start winning confirmation process shown in FIG.
If the determination is positive, the jackpot determination random number, the jackpot symbol determination random number, the reach determination random number, the fluctuation pattern determination random number, etc. are read from the corresponding counters, and the special symbol hold memory is full (four in this embodiment). Whether or not (S41). As described with reference to FIG. 2, the special symbol on-hold storage display device 10 uses the four on the left side for the special symbol 1 and the four on the right side for the special symbol 2.
If the reserved memory is not full (S41: no), each random number is stored as the special symbol reserved memory, and the number of lighting of the special symbol reserved memory display device 10 is increased by 1 (S42). If there are already four reserved memories (S41: yes), no reserved memories are stored, and the number of lighting of the special symbol reserved storage display device 10 is not increased.
In addition, the increase / decrease in the number of reserved symbols of the special symbol is transmitted to the effect symbol control device 82 via the sub integrated control device 83, and the number of lighting of the special symbol reservation memory display device 10 is displayed on the screen 6 a of the effect symbol display device 6. The same number of pseudo-hold indications are displayed. Of course, the pseudo hold display is not necessarily required.

In the success / failure determination process shown in FIG. 10, main controller 80 determines whether or not the condition device is operating based on the jackpot flag (S50). If the determination in S50 is negative, the special symbol is not changing (S51: no), and the confirmed symbol is not being displayed (S52: no), whether or not there is a special symbol hold memory (the hold memory in S42). Is determined (S53).
If there is this reserved memory (S53: no), the oldest one of the special symbol reserved memories is read and the special symbol reserved memory is deleted from the reserved memory. It is determined whether (high probability state) or not (S54).
If the determination is affirmative (S54: yes), the read jackpot determination random number is checked against the hit value recorded in the probability variation table (S56). If the determination is negative, the read jackpot determination random number is stored in the normal table. It collates with the recorded hit value (S55).
In this embodiment, the player wins with a probability of 1/350 in the normal probability state and wins with the probability of 1/35 in the high-probability gaming state.

If the determination in S55 or S56 is successful (S57: yes), the winning symbol is determined by the winning symbol determining random number (S58), and the variation pattern is determined by the variation pattern determining random number (S59).
If it is off (S57: no), it is next determined whether or not it is a small hit (S61). If the determination is successful (S61: yes), the small winning symbol is determined, and the variation pattern is determined by the variation pattern determination random number (S62). In the present embodiment, since only one symbol for winning a small winning is provided, there is no need to perform symbol determination processing. Of course, it may be configured to perform the symbol determination process.
When the small hit is off (S61: no), the variation pattern is determined based on the reach determination random number and the variation pattern determination random number (S63). In the case of the present embodiment, since there is only one type of special symbol “-” in the case of detachment, it is not necessary to determine the detachment symbol.

Subsequent to S59, S62, or S63, data indicating the above-mentioned lottery result, specifically, one of normal jackpot, probability variation jackpot, missed reach (missed but with reach display), or missed with no reach display. A variation start command (display control command) including variation pattern data specifying data and variation time is output to the sub-integrated control device 83, and the special symbol display device 9 is controlled to start variation display of the special symbol. (S60).
Accordingly, the sub-integrated control device 83 can determine the jackpot symbol or the off symbol (hereinafter collectively referred to as a fixed symbol), the presence / absence of reach, and the variation time based on the variation start command.
Receiving the variation start command, the sub integrated control device 83 performs sound and lamp effect control in response to the special symbol variation display, and sends a variation start command to the effect symbol control device 82.

If the special symbol is changing (S51: yes), main controller 80 determines whether or not a predetermined symbol change time (based on the change pattern of S59 or S62, S63) has elapsed as shown in FIG. Judgment is made (S64).
If the determination is affirmative (S64: yes), a symbol stop command is output to the sub-integrated control device 83 (S65), and the special symbol display device 9 is controlled to display the confirmed symbol.
Receiving the symbol stop command, the sub integrated control device 83 ends the sound and lamp effects in response to the special symbol variation display, and sends a symbol stop command to the effect symbol control device 82.

If the special symbol that has been confirmed and displayed is a jackpot (S66: yes), main controller 80 sets the symbol to be displayed (S67), and sets the jackpot flag through the conditional device operation start process (S68). To do.
Subsequently, it is determined whether or not the probability variation flag is set (S69). If the determination is affirmative, the probability variation flag is cleared (S70). If the determination is negative (S69: no), it is determined whether or not the time reduction flag is set (time reduction state) (S71). If the determination is affirmative, the time reduction flag is cleared (S72).

If the special symbol that has been confirmed and displayed is not a big hit (that is, missed) (S66: no), it is determined whether the combination is a small hit as shown in FIG. 12 (S73).
If it is a small win (S73: yes), the determined symbol display setting process (S75) is performed in the same way as the big win, and then it is determined whether or not the hourly flag is 1 (S76).
When the time reduction flag is 1 (S76: yes), 1 is subtracted from the open extension operation count (S77).
If the number of times that the opening extension can be performed becomes 0 by subtracting 1 (S78: yes), the operation of the opening extension function is set to end by setting the time reduction flag to 0 (S79), and after the small hit game processing described later is completed Stop the open extension function. Since the small hit game according to the present embodiment is not handled as a cause of changing the game state, the number of times that the open extension can be extended is not increased, reduced, started, stopped, etc. due to the small hit.
When the time reduction flag is not 1 (S76: no), when the number of times of release is not 0 (S78: no), the process directly proceeds to the special game process.

  Returning to FIG. 10, when the confirmed symbol is being displayed (S52: yes), it is determined whether the defined symbol display time has ended as shown in FIG. 13 (S80), and when it is completed (S80: yes), it is confirmed. The symbol display is terminated (S81). If the display time has not ended (S80: no), the process proceeds to the special game process.

In the special game process shown in FIG. 14, the main controller 80 determines whether or not the condition device is operating based on the jackpot flag (S91).
If the condition device is operating (S91: yes), it is determined whether or not the special winning opening 13 is open (S92). In addition, although the game structure of a present Example is provided with two special symbols, it has demonstrated by the structure shared by one big prize opening. Of course, it may be configured to have a dedicated prize opening for each, or may be used according to the number of open jackpots and is optional.

If the big prize opening 13 is not being opened (S92: no), it is determined whether the big hit game start effect is being produced (S93). The jackpot is also described as a special hit and a special symbol hit, and refers to the same thing. It is arbitrarily selected and described in the explanation flow.
When it is not during the jackpot game start effect (S93: no), it is next determined whether or not the big winning opening 13 is closed during the jackpot interval (S94). If it is not during the jackpot interval (S94: no), it is determined whether the jackpot end effect is being performed (S95).
If this is also a negative determination (S95: no), it is determined that the state of starting the jackpot game is now started, so the jackpot symbol and the jackpot game state are stored (S96), and the jackpot game start effect process (S97) ), A jackpot start command is transmitted to the sub integrated control device 83, and the special winning opening 13 is opened.
The sub-integrated control device 83 starts a jackpot voice and lamp effect, and sends a jackpot start command to the performance symbol control device 82. The effect symbol control device 82 that has received the jackpot command controls the effect symbol display device 6 to display a jackpot start effect (so-called fanfare screen). The big winning opening 13 is opened after the jackpot start effect.
When the condition device is not in operation (S91: no), during the jackpot start effect (S93: yes), during the jackpot interval (S94: yes), when the jackpot end effect (S95: yes) The process proceeds to the small hit game processing.

When the big winning opening 13 is open (S92: yes), it is determined whether ten game balls have won the big winning opening 13 (S98). In this embodiment, the number is 10, but it may be 9 or 8, and is not particularly limited.
When ten game balls are won in the big winning opening 13 (S98: yes), the big winning opening closing process is performed (S100).
If the number of winnings is less than 10 (S98: no), it is determined whether the opening time of the big winning opening is over (S99). In this embodiment, in the case of a big hit in 15 rounds, the maximum opening time of each round is set to 28 seconds. Of course, it is not limited to this number of seconds.
When the opening time has expired (S99: yes), a special winning opening closing process (S100) is performed, and then it is determined whether it was the final round (101). If it is not the final round (S101: no), the jackpot interval process (S102) transmits an interval command to the sub-integrated control device 83, and the control of the effect symbol control device 82 that has received the interval command from the sub-integrated control device 83. Waiting for the screen display of the effect symbol display device 6 to be changed, the first big prize opening 13 is opened.
If the opening time has not ended (S99: no), the process directly proceeds to the small hit game process.

If the affirmative determination is made in S101, the jackpot operation is not continued, so the jackpot end effect process (S103) is executed as shown in FIG. 15, and then the condition device is stopped by the condition device stop process (S104) (the jackpot flag is set). clear).
Then, if the winning symbol that is confirmed and displayed on the special symbol display device 9 in S67 and stored in S96 is a probability variation symbol (S105: yes), the probability variation flag is changed to 1 (S106). When the probability variation flag is set to 1, in this embodiment, the winning probability of the special symbol is improved, the average variation time of the special symbol is shortened, the opening extension function of the ordinary electric accessory 12 is set, and the value of the opening extension counter is set to 10,000.
If it is not a probable variation symbol (S105: no), the hourly flag is changed to 1 (S107). When the time-short flag is set to 1, in this embodiment, the average change time of the special symbol is shortened, the opening extension function of the ordinary electric accessory 12 is set, and the opening extension counter value is set to 100.
The set content is an example. For details such as the latent effect performed in conjunction with the small hit game, which will be described later, a probability variation flag = 2 is provided. When the flag is 2, a special symbol winning probability improvement only is given. It is conceivable to set the flag to 1 on the condition that the flag 2 is selected again in the state of.

After each flag is set, the priority digest target, which is a feature of the present invention, is set. After setting each flag, it is determined whether the priority object is the special symbol 1 corresponding to the first start port 11 or the special symbol 2 corresponding to the second start port 12, and it is referred to whether the special symbol 1 is the target ( S108). For example, as shown in FIG. 17A, probability fluctuations and priority targets are assigned to symbols, and determination is made according to the setting.
If the determination is affirmative, the special symbol 1 is set as a priority digestion target (S109). If the determination is negative, the special symbol 2 is set as a priority digestion target (S110). For example, in the case of a big hit with symbol 5 in the setting of FIG. 17A, since it is a probability variation symbol (S105: yes), the probability variation flag is set to 1 (S106), and the priority target is not 1 (S108: no) ), Special symbol 2 priority digestion setting is performed (S110).
After the process of S109 or S110, a jackpot end command is transmitted to the sub integrated control device 83 (S111).
The above is the special game process.

Next, the small hit game process shown in FIG. 16 will be described.
First, it is determined whether or not the special winning opening 13 is open (S112). In the case of negative determination (S112: no), it is determined whether a small hit start effect is being performed, and in the case of negative determination (S113: no), it is determined whether it is during the interval between small hit games (S114).
If it is not an interval between the small hit games (S114: no), and if it is not in the small hit game end effect (S115: no), it is determined that the small hit game is now started. The small winning game state is stored (S116), and the small winning start command is transmitted to the sub-integrated control device 83 by the small winning game start effect process (S117), and the special winning opening 13 is opened.
The sub-integrated control device 83 starts the sound of the small hitting sound and the lamp, and sends a small hitting start command to the effect symbol control device 82. Receiving the small hit command, the effect symbol control device 82 controls the effect symbol display device 6 to display a small hit start effect (so-called fanfare screen). The large winning opening 13 is opened after waiting for the small hitting start effect.

If the big prize opening 13 is open (S112: yes), it is determined whether ten game balls have won the big prize opening 13 (S118). In the case of a small win, it is conceivable that the maximum winning number is not set because the opening time is very short.
When the maximum number of winning prizes has been reached (S118: yes), the closing process of the special winning opening 13 is performed (S120).
If the number has not reached 10 (S118: no), it is determined whether the maximum opening time of the special winning opening 13 has been reached (S119). In this embodiment, the maximum opening time is 0.8 seconds. Therefore, the maximum number of winnings 10 is a number that is impossible. This is based on the idea that there is no need to give a prize ball, mainly because it is used as an opportunity to switch production.
When performing the so-called latent production described above, the opening time at the time of the second round big hit is also the same, so that the player can not determine whether it is a big hit or a small hit just by looking at the opening action of the second big prize opening It has become.
If the opening time has been reached (S119: yes), the special winning opening 13 is closed (S120), and if not reached (S119: no), the process returns.

After closing the big winning opening 13, it is determined whether it was the final round (S121). In this embodiment, the small hit game is set to 2 rounds. In particular, it is not limited to two rounds.
If it is the final round (S121: yes), the small hitting operation is not continued, so the small hitting end effect process (S123) is executed and a small hitting end command is transmitted to the sub integrated control device 83 (S124).
If it is not the final round (S121: no), an interval process between small games is performed (S122), and the process returns to the return.
The above is the small hit game processing. In the case of a small hit, the condition device does not operate, so the probability variation flag, the short time flag, etc. are not set, and only the gaming state at the small hit is returned.

FIG. 17 shows three characteristic patterns of allocation of priority digest targets in the probability variation function and priority digest target allocation for special symbols.
As shown in FIGS. 9 and 10, the stop mode of the symbol at the time of jackpot is determined by the jackpot symbol determination random number acquired when the game ball wins each starting port. The setting contents of the priority object are set in advance together with the setting contents of the flag. Thereby, only by determining the stop mode of the jackpot symbol, the gaming state and the priority digest target are determined.

FIG. 17A is a classification table in which priority digest targets are equally distributed.
In this embodiment, the probability variation and the priority digest target are set in a distributed manner. Probability variation not activated and priority special symbol 1,2. Stochastic operation and priority special symbols 1,3. Probability variation not activated and priority special symbol 2,4. Four game states of the probability variation operation and the priority target special symbol 2 are formed.
Of course, as described above, in the case of a game configuration that performs a latent production, adding `` open extension function '' and `` variable time reduction function '' as a division, it will form more diverse game states, In the case of a game configuration in which the operation condition of the release extension function is special, such as when the flag 2 is acquired again in the state of the probability change flag 2 described in the paragraph 0059, the “open extension function” is added. It will be.
FIG. 17B is a set division table in which priority digestion targets are not uniform and are biased toward the special symbol 2. By doing in this way, while special symbol 2 is basically a priority object, sometimes special symbol 1 is sometimes a priority object, and other game states are randomly generated while forming a basic game structure. It is possible to prevent the game from becoming rutted.
FIG. 17 (c) does not perform preferential digestion. It is a division table to which the gaming state is added. The fact that priority digestion is not performed means that the validity determination process shown in FIGS. 10 to 13 is performed, which means that digestion is performed from the oldest retained memory regardless of the first start suspension and the second start suspension.
By doing so, 1. No priority. Special symbols for priority digestion 1,3. Three gaming states of the special digest target special symbol 2 can be formed. Of course, as described above, by adding the “open extension function” and the “variable time shortening function”, a plurality of game states can be generated.

FIG. 18 is a special 1 priority determination process performed in place of FIG. 10 when the special symbol 1 becomes a priority target due to the special symbol stop mode that is a big hit (S109). Note that the same processes as those in FIG. 10 are denoted by the same reference numerals and description thereof is omitted, and different points are newly described by adding reference numerals.
As in FIG. 10, if the condition device is not operating (S50: no), the symbol is not changing (S51: no), and the final symbol is not displayed (S52: no), the special symbol 1 is suspended. It is determined whether the memory is 0 (S150). If the special symbol 1 has a start-up storage (S150: no), the oldest memory of the special symbol 1 is read, the probability variation flag determination (S54), the big hit determination (S57), the small hit determination (S61) are performed, and the variation pattern is displayed. Determination (S59, S62, S63) is performed, and a change start command is transmitted to the sub-control device 83 (S60).
If the special design 1 start hold memory is 0 (S150: yes), the process proceeds to FIG. 19A to determine whether the special design 2 start hold memory is 0 (S151). If the start hold memory is 0, the process proceeds to the special game process.
If there is a start-pending memory for special symbol 2 (S151: no), returning to FIG. 18, as in the case of special symbol 1, the oldest memory of special symbol 2 is read and the probability change flag determination (S54), jackpot determination ( S57), a small hit determination (S61) is performed to determine a variation pattern (S59, S62, S63), and a variation start command is transmitted to the sub-control device 83 (S60).
The above is the determination processing of whether or not the special symbol 1 is selected as the priority object in S109.

FIG. 20 shows a special 1 priority determination process performed in place of FIG. 10 when the special symbol 2 becomes a priority target (S110). In this case, the same processes as those in FIG. 10 are denoted by the same reference numerals and description thereof is omitted, and different points are newly described by adding reference numerals.
As in FIG. 10, if the condition device is not operating (S50: no), the symbol is not changing (S51: no), and the final symbol is not being displayed (S52: no), the special symbol 2 is suspended. It is determined whether the memory is 0 (S201). If the special symbol 1 has a start-up memory (S201: no), the oldest memory of the special symbol 2 is read, the probability variation flag determination (S54), the big hit determination (S57), the small hit determination (S61) are performed, and the variation pattern is displayed. Determination (S59, S62, S63) is performed, and a change start command is transmitted to the sub-control device 83 (S60).
If the special symbol 2 start hold memory is 0 (S201: yes), the process proceeds to FIG. 19B, and it is determined whether the special symbol 1 start hold memory is 0 (S202). If the start hold memory is 0, the process proceeds to the special game process.

If there is a start-up storage of special symbol 1 (S202: no), returning to FIG. 20, as in the case of special symbol 2, the oldest memory of special symbol 1 is read and the probability change flag determination (S54), jackpot determination ( S57), a small hit determination (S61) is performed to determine a variation pattern (S59, S62, S63), and a variation start command is transmitted to the sub-control device 83 (S60).
The above is the determination process of whether or not the special symbol 2 is selected as the priority object in S110.

The above is the configuration of the first embodiment, but by changing the target of priority digestion in the special symbol stop mode, the priority digestion target is involved in addition to the operation of the probability variation and the open extension function, so the player Will be interested in which stop mode will be hit, and the fun of the game will improve.
In addition, when the selection rate is different between the special symbol 1 and the special symbol 2, one of them is arranged as a base of the game and the other game is given by the uncertain element of pulling the stop mode. While maintaining the outline, it is possible to randomly generate different game characteristics to prevent the game from becoming rutted and to give unexpectedness.
Moreover, priority digestion is not performed. By having this option, it is possible to provide a variety of game playability to the player. In particular, the combination of the priority digestion OFF, the special symbol 1 priority digest, the special symbol 2 priority digestion, the probability variation, the opening extension function, and the like can set various advantages of the player.

[Second Example A]
The second embodiment is configured such that when the same special symbol is selected for a predetermined number of times in the priority target selection method of the first embodiment, another special symbol is forcibly set as a priority target. Therefore, the same parts and the same processing contents as those in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and different points are described. Further, in order to explain patterns that are the same in large configuration but differ in control content, the second embodiment is divided into three parts, A to C, for explanation.

The process shown in FIG. 21 shows the special game process of the second embodiment A by modifying the special game process of the first embodiment shown in FIGS. 14 to 15 and the process shown in FIG.
As shown in FIG. 14, when the condition device is in operation (S91: yes), and the closing process is performed after the special winning opening is opened (S92: yes) (S100), when it is the final round (S101: yes) Moves to FIG. 21 and performs a jackpot end effect process (S103).
After stopping the condition device (S104), it is determined whether the jackpot stop mode (FIG. 14, S96) is a probable change (S105), and then it is determined whether the priority object is the special symbol 1 (S108).
When the special symbol 1 is the target of preferential digestion (S108: yes), it is referred to whether the special symbol 1 which is a process peculiar to the second embodiment is selected five times in succession (S301). When it reaches 5 times (S301: yes), the reverse special symbol 2 is set as the priority digestion target (S110). In this case, since it is different from the stop mode of the special symbol, it is desirable to notify the effect symbol display device 6. In addition, as shown in FIG. 27B, it can be considered that the limiter is activated at the next hit at the fourth stage. In this example, the display is performed so that the character 96 describes the state comment 95.

If the number has not reached 5 (S301: no), the special symbol 1 is set as a priority digestion target (S109).
When the priority digest target is the special symbol 2 (S108: no), it is referred to whether the special symbol 2 has been selected five times in succession (S302). When it reaches 5 times (S302: yes), the reverse special symbol 1 is set as the priority digestion target (S109). If the number has not reached 5 (S302: no), the special symbol 2 is set as a priority digestion target (S110).
When the priority digest target setting is completed (S109, S110), a jackpot end command is transmitted to the sub-control device 83 (S111), and the special game process is terminated.
The above is the second embodiment A, but if the priority digestion target is the same continuously up to a predetermined number of times, it is possible to prevent biasing to each gaming state by operating the limiter and changing the priority digestion target to the other. Can do. As a result, even in gaming machines having various gaming states, the player can increase the chances of enjoying each gaming state evenly.

[Second Example B]
Subsequently, in the second embodiment B, the basic control content is the same as A. However, it differs from A in that an option of not setting a priority digest target is provided.
The process shown in FIG. 22 shows the special game process of the second embodiment B by modifying the special game process of the first embodiment shown in FIGS. 14 to 15 and the process shown in FIG.
As shown in FIG. 14, when the condition device is in operation (S91: yes), and the closing process is performed after the special winning opening is opened (S92: yes) (S100), when it is the final round (S101: yes) Moves to FIG. 21 and performs a jackpot end effect process (S103).
After stopping the condition device (S104), it is determined whether the jackpot stop mode (FIG. 14, S96) is a probable change (S105), and then it is determined whether the priority object is the special symbol 1 (S108).
When the special symbol 1 is the target of preferential digestion (S108: yes), it is referred to whether the special symbol 1 which is a process peculiar to the second embodiment is selected five times in succession (S301). When it reaches 5 times (S301: yes), a setting is made so that neither of them is subject to priority digestion (S303). Also in this case, since it is different from the stop mode of the special symbol, it is desirable to notify the effect symbol display device 6. By the way, when the special symbol is changing, it is better to display the priority digest target as shown in FIG. Of course, it is good to notify also when priority digest is not performed like S303.

If the number has not reached 5 (S301: no), the special symbol 1 is set as a priority digestion target (S109).
When the priority digest target is the special symbol 2 (S108: no), it is referred to whether the special symbol 2 has been selected five times in succession (S302). When it reaches 5 times (S302: yes), a setting is made so that neither of them is subject to priority digestion (S304). If the number has not reached 5 (S302: no), the special symbol 2 is set as a priority digestion target (S110).
When the priority digest target setting is completed (S109, S110, S303, S304), a jackpot end command is transmitted to the sub-control device 83 (S111), and the special game process ends.
Although the above is 2nd Example B, when the priority digest object is the same continuously for a predetermined number of times, it can prevent biasing to each game state by operating a limiter and ending preferential digestion. In addition, it is possible to create a relatively gentle game in order to prevent the preferential digestion function from continuing a significantly advantageous state.

[Second Example C]
In the second embodiment C, unlike A and B, the determination is made with reference to the number of consecutive points at the point where the jackpot symbol is determined.
FIG. 23 shows the success / failure determination process of the second embodiment C based on FIG. Therefore, FIGS. 11, 12, and 13 are shared.
If the condition device is not operating (S50: no), and neither the change nor the fixed symbol display is being displayed (S51: no, S51: no), the reserved storage is referred to, and if it is not 0 (S53: no), the probability change flag is set. Reference is made (S54). If it is determined whether or not the table is correct and normal and it is a big win (S57), the priority target continuous number reference, which is a process peculiar to the second embodiment C, is performed (S350).
In the present embodiment, as in the second embodiment A and B, in order to limit up to 5 times continuously, in S350, it is referred to whether the object is the same continuously 4 times.
For example, if the determination is made with only the jackpot symbol determination random number, the symbol “7” in FIG. Then, since it is desired to set the priority object to the special symbol 1 while maintaining that the probability variation function operates, the jackpot symbol is determined by changing to the symbol “1” or “3” (S58).
After that, the variation pattern is determined (S59), and a variation start command is transmitted to the sub-control device 83 (S60).
The above is the control of the second embodiment C, but since the change is made in advance at the point of the stop pattern of the jackpot symbol as compared with A and B, the jackpot symbol for the player while achieving the same effect as A and B. Since the stop mode and the gaming state to be given match, there is an effect that does not cause confusion.

[Third Example A]
The third embodiment has a configuration in which, when the number of changes in the special symbol reaches a predetermined number in the priority object selection method of the first embodiment, another special symbol is forcibly set as a priority object. Therefore, the same parts and the same processing contents as those in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and different points are described.
Further, in order to explain patterns that are the same in large configuration but differ in control content, the third embodiment is divided into two parts A and B for explanation.

FIG. 24 shows the success / failure determination process of the third embodiment A, and FIG. 24 and FIG.
If the condition device is not operating (S50: no), and neither the change nor the fixed symbol is displayed (S51: no, S51: no), the reserved memory of the special symbol 1 is referred, and if it is other than 0 (S150: no) ) Add 1 to the number of fluctuations, which is a process unique to the third embodiment A (S401).
After 1 is added to the number of changes, it is determined in this embodiment whether the number of changes has reached 200 (S402). Here, it is 200 times, but the number of times setting is arbitrary.
If it has not reached 200 times (S402: no), the process proceeds to FIG. 25 to perform a probability variation determination (S54), a success / failure determination (S57), a small hit determination (S61), and the like to determine a variation pattern (S59, S62). , S63) A change start command is transmitted to the sub-control device 83 (S60).
If it has reached 200 times (S402: yes), the priority object is changed to the special symbol 2 (S403), and the success / failure determination process ends.
In addition, while counting 200 times, it is good to display so that the frequency | count of a fluctuation | variation from which a limiter will act | operate like FIG.27 (c) can be known.
The above is the processing of the third embodiment A, but unlike the second embodiment, it is changed according to the number of fluctuations, so that the priority digest target can be switched in the process up to the jackpot game, giving the player a variety of playability If given, it can make it possible to aim for a big hit.

[Third Example B]
Subsequently, in the third embodiment B, the basic control content is the same as A. However, it differs from A in that an option of not setting a priority digest target is provided.
If the condition device is not operating (S50: no), and neither the change nor the fixed symbol is displayed (S51: no, S51: no), the reserved memory of the special symbol 1 is referred, and if it is other than 0 (S150: no) ) Add 1 to the number of fluctuations (S401).
After 1 is added to the number of changes, it is determined in this embodiment whether the number of changes has reached 200 (S402).
If it has not reached 200 times (S402: no), the process proceeds to FIG. 25 to perform a probability variation determination (S54), a success / failure determination (S57), a small hit determination (S61), and the like to determine a variation pattern (S59, S62). , S63) A change start command is transmitted to the sub-control device 83 (S60).
When it has reached 200 times (S402: yes), the setting specific to the third example B is set so that priority digestion is not performed in either (S503), and the success / failure determination process ends.
The above is the processing of the third embodiment B. With this, a gaming state in which the preferential digestion is executed only a predetermined number of times, so that the performance by the preferential digestion can be improved as compared with the prior art.
As the degree of advantage is improved, the gaming state is highly interesting for the player, and the function increases the game value along with the probability variation and variation shortening functions.
In the present embodiment, the description has been made by unifying 200 times. However, as shown in FIG. 17, a special symbol may be provided with a number of limiters in advance, and a plurality of limiters may be provided. In that case, the number of times of reference in S402 in FIG. 26 varies depending on the stop pattern of the jackpot symbol.
If you do this, how much priority digestive function is given? Which is the subject of priority digestion? This will create an excitement that will give more fun to the player.

[Fourth Embodiment A]
Next, a fourth embodiment A will be described.
In the fourth embodiment, only the first start port 11 is used as a start port for determining whether or not to play a special game, and the ordinary electric accessory 12 does not function as a second start port. Therefore, the special game that is a big hit is executed only when the game ball wins the chucker 11 as the first starting port and a predetermined success / failure random number value is extracted.
When a game ball wins the first starting port 11, the value of the counter is extracted, which is incremented by 1 every 2 ms and an integer of 0 to 399 is repeatedly created. Since the timing at which the game ball wins at the first starting port is random, the extracted counter value functions as a real random number.
If the value of the extracted counter is “1”, “333” or “777” is displayed on the screen 6a, and the big winning opening 13 is opened for 30 seconds or until 10 game balls are won. The first special game that is an opening and closing operation that repeats 16 times is executed.
When “777” is displayed on the screen 6a, a high probability (probability change) is obtained after the special game is executed. Specifically, the first special game that displays “777” on the screen 6a is executed even if the value of the extracted counter is [1], “13”, “17”, [19], or [21].
If the extracted counter value is “11”, a combination of the same three-digit symbols other than “333” and “777” is displayed on the screen 6a, and the winning prize opening 13 is opened for 1 second. A second special game that is executed only once is executed.
In addition, when one game ball is won in the big winning opening 13, 15 game balls are paid out to the player as prize balls.

  In the present embodiment, in order to comply with the legal ball-off rate, the probability of occurrence of a special game is set to 1/400, and the ball-entry rate (winning rate), the probability variation continuation rate, etc. of the first start port 11 are determined. . The entrance rate is determined by adjusting the interval and angle between the two game nails just above the start port 11. In this embodiment, 99 game balls are fired per minute. The measurement of the entrance rate is performed by adjusting the launch force so that the game ball wins the most at the start port 11.

In this embodiment, since the number of prize balls acquired by the second special game is very small, the pitch rate is designed based on the probability of generating the first special game. As a result, it is possible to reduce the occurrence of special games.
For example, if the probability of occurrence of the first special game is 1/500, the probability of occurrence of the second special game is 1/300, the probability of occurrence of the average special game is 1/400, and the pitch rate is designed, In 2 special games, a real prize ball could not be obtained, and the occurrence frequency of the first special game could be biased.
The present invention solves this problem and exhibits the effect of making the pachinko gaming machine more sound.

[Fourth embodiment B]
A fourth embodiment B will be described.
In the fourth embodiment B, if the value of the extracted counter is “11”, a combination of the same three-digit symbols other than “333” and “777” is displayed on the screen 6a, and the winning prize opening 13 is 7 seconds. The second special game is executed in which the release operation is repeated 10 times. The first special game is the same as in the fourth embodiment A.

In the present embodiment, in order to comply with the legal ball-off rate, the probability of occurrence of a special game is set to 1/200, and the ball-entry rate (winning rate), the probability variation continuation rate, etc. of the first start port 11 are determined. .
In this embodiment, the number of prize balls acquired by the second special game is not less than that of the first special game. For this reason, as in the prior art, the pitching rate is designed based on the probability of generating the first special game and the second special game.

Although the second specific example of the present invention has been described above, the number of times and the time can be appropriately changed within the scope not departing from the gist of the present invention. For example, in the opening operation of the second special game, the opening time may be 6 seconds or less and the opening / closing frequency may be two. However, even the second special game may be regarded as the first special game if the next jackpot is guaranteed by so-called “accuracy”. In short, if the number of award balls that can be acquired by the second special game is extremely small compared to the first special game, it may be configured to calculate the pitch rate based on the occurrence probability of the first special game.
In the present embodiment, the first special game and the second special game are distinguished by the difference in the extracted random number value. However, the extracted random number value is used in common, and other random numbers, for example, jackpots are used. You may distinguish by the difference of a design random number.
Furthermore, in the fourth embodiment A, when the probability of occurrence of a special game combining the first special game and the second special game is 1/400, and the ratio of the second special game is 20% of the total special game, The probability of occurrence of a special game for calculating the pitch rate may be designed as 1/400 × (80/100) = 1/500.
