Description

Description: TECHNICAL FIELD The present invention relates to a ball game machine that presents a specific game state in which a predetermined game value can be given to a player, and in particular, the appearance of the specific game state. The present invention relates to a ball game machine capable of changing the probability.

[Prior Art] Conventionally, as a ball game machine that presents a specific game state in which a predetermined game value can be given to a player, for example, a combination of displays when a plurality of variable display members is stopped is a predetermined display. When the mode (for example, all the display is "7"; hereinafter referred to as a big hit), it becomes a specific game state until the variable winning ball device provided on the game board has a predetermined time or a predetermined number of winning balls. The open form is known. In such a ball game machine, the occurrence probability of the specific gaming state depends on the occurrence probability of a large hit of the variable display member.

By the way, the probability of occurrence of the above-mentioned variable display member which is a big hit is set to be constant by the game control program. For this reason, the frequency of occurrence of the specific game state per unit time is large in the winning rate to the starting winning opening that allows the variable driving of the variable display member, that is, the adjusting condition of the obstacle nail planted near the starting winning opening. Will be affected.

[Problems to be Solved by the Invention] As described above, the frequency of occurrence of the specific game state in the conventional ball-playing machine largely depends on the degree of adjustment of the obstacle nail. Was required. Also, if the degree of adjustment of the nail is checked, it is easy for a skilled game player to determine whether or not the specific game state of the ball game machine is likely to occur. I was

Therefore, in order to eliminate the above-mentioned inconvenience, it is only necessary to change the game control program so that the probability of a big hit can be adjusted, but in this case, the probability setting made by the person in charge of the game hall before the start of business is set. , There is a problem that other employees collude with the player during business, and fraudulent acts that change it for the player's advantage occur, and with the adjustment properly made by the person in charge of the amusement hall Even if there is, there is a problem that doing it during business leads to a player's distrust.

The present invention has been made in view of the above-mentioned problems, and an object thereof is to adjust the occurrence rate of a specific game state without requiring a high level of skill in adjusting nails, and it is illegal. Another object of the present invention is to provide a ball-and-ball game machine that can prevent actions and that does not cause the player to feel distrust.

[Means for Solving the Problem] In order to achieve the above-mentioned object, the ball game machine according to the present invention operates a probability setting operation means for setting a probability of occurrence of a specific game state on a game hall side. Accordingly, the probability setting means that can be selectively set within the range of a plurality of types of probabilities prepared in advance, and until the predetermined period has elapsed, regardless of the probability changing operation by the probability setting operation means, the probability setting means Probability maintaining means for maintaining the set probability before the operation is provided.

[Operation] The probability of occurrence of a specific game state changes when the person in charge of the game hall operates the probability setting operation means. This probability of occurrence is set within a range of a plurality of types prepared in advance.
Therefore, it is possible to adjust the payout rate caused by adjusting the nails by the probability of occurrence of the specific game state,
Adjustment of nails does not require so high skill.

Even if the probability setting operation means is operated, the newly set probability is not immediately reflected by the action of the probability fiber means. The new probability due to the operation of the probability setting operation means operates when the predetermined period has passed. Therefore, even if the probability setting operation means is operated during business, its effect is not reflected, so there is no point in performing the operation during business, so that it may lead to misconduct of 4 employees and distrust of the player. It is possible to prevent such acts.

In this way, the setting probability before and after the operation of the probability setting switch 57 is displayed, even if the setting probability is changed by pressing the probability setting switch 57, the changed setting probability is reflected in the game. This is because, after a certain period of time has passed, the setting probability that is still continued and the setting probability that is changed after the certain period of time are displayed to eliminate erroneous operation.
If the probability setting operation means is not a push button type like the embodiment but a lever with a scale, the setting indicator 58b for the next time is not necessary.

On the other side of the probability setting switch 57, a variable display circuit indicator 59 is provided. This variable display counter 59
Indicates the number of times that the drum-shaped variable display members 68a to 68c of the variable display device 60 and the variable display 66 are variable, and at the time of being reset, a predetermined constant number (for example, 200
0) is displayed, and "1" is subtracted each time a variable operation is performed based on the detection signals from the starting prize winning ball detectors 36a to 36c. Then, when the display becomes "0", the next setting probability set by the probability setting switch 57 comes into effect. That is, in the case of this embodiment, the number of remaining times (number within 2000; displayed on the variable display number indicator 59 at the time when the person in charge of the game operates the probability setting switch 57)
Until the elapse of a predetermined period), the changed setting probability is not reflected in the game. Therefore,
The set probability set before operating the probability setting switch 57 is maintained for a period until the remaining number displayed on the variable display number display 59 becomes "0". In addition,
Current set value display 5a, next set value display 58b,
The data displayed on the variable display counter 59 is backed up and stored as is even when the power is turned off, and the data when the power is turned off is displayed when the power is turned on again. ing.

Next, by operating the probability setting switch 57 described above,
Variable display device 60 directly related to the probability of occurrence of a specific game state
With reference to FIGS. 2 and 4 to 6, the configuration of the variable display device will be described.

The variable display device 60 is divided into a mounting board 61 mounted on the front surface of the game board 13 and a storage box 70 for storing a drive mechanism portion mounted on the back surface of the game board 13.
Therefore, first, the mounting board that is mounted on the surface of the game board 13
The configuration of 61 will be described.

A normal winning opening 63 is formed on the top of the mounting board 61, and an upper decorative plate 62 is attached to the front surface of the normal winning opening 63. Further, a transparent front cover lens 64 is attached in an arc shape on the lower portion of the attachment substrate 61. The front cover lens 64 is selected to have a size such that three patterns drawn on the surfaces of the drum-shaped variable display members 68a to 68c can be seen, and in particular, the magnifying lens portion 65 is selected so that the central pattern can be seen larger. I am configuring.

A variable display 66 is provided above the front cover lens 64 and in the center of the upper decorative plate 62. This variable display
The 66 uses a 7-segment LED as an electrically variable display member to display five kinds of symbols of "7", "C", "E", "H", and "J", and the drum-shaped variable display. It is provided for displaying the big hit mode in cooperation with the members 68a to 68c. That is, when the combination of the display mode of the drum-shaped variable display members 68a to 68c and the display mode of the variable display 66 is a predetermined jackpot mode, the variable winning ball device 16 is advantageous to the player. It is something that changes into a state. The variable display 66 is used to display the number of times the opening / closing plate 17 of the variable winning ball device 16 has been opened when the specific game state is entered.

Further, on the upper decorative plate 62, start prize winning memory indicators 67a to 67d are provided below the variable indicator 66. The start prize winning memory display devices 67a to 67d are for displaying the winning prizes stored by winning the start prize winning openings 20a to 20c while the variable display device 60 is operating. To be done. Therefore, at the time when the operation of the variable display device 60 ends, if the start winning award memory indicators 67a to 67d are lit, the variable display device 60 operates again by the number of the lights, and each time the operation starts. Turn off the lights one by one.

By the way, a combination of the above-mentioned drum-like variable display members 68a to 68c and the display mode which is a big hit mode of the variable display 66 is set as follows. That is,
In order to become a big hit mode, the drum-shaped variable display member 68a
The display displayed in the central portion (the magnifying lens portion 65) of ~ 68c is "Zero eyes" (drum-shaped variable display member 68 as described later).
a to 68c display 10 kinds of numbers "0 to 9"),
When “7” is displayed on the variable display 66 out of the five types, the big hit mode is achieved. The drum-shaped variable display member 68
The probability of "Zoro eyes" appearing in a to 68c is (1/10 x 1/10 x 1/10) x 10 = 10/1000 = 1/100.

On the other hand, the probability that "7" is displayed on the variable display 66 is set in five steps as shown in FIG. 6 (a), and the step can be selectively set by operating the probability setting switch 57. Has become. So, in the setting, 10
Two pieces of the identification information are "7", three pieces of the identification information of 10 are "7" in the setting, and four pieces of the identification information of 10 are "7" in the setting. 7 ”, 5 out of 10 pieces of identification information are“ 7 ”in the setting, and 6 pieces out of 10 pieces of identification information are“ 7 ”in the setting. Therefore, the display of the drum-shaped variable display members 68a to 68c is "double eyes", and the variable display 66
The probability of occurrence of the big hit mode in which the display of "7" is "7" is as shown in FIG. 6 (b). That is, when the setting is selected with the probability setting switch 57, the probability of occurrence of the jackpot mode is 2/1000, and when the setting is selected, the probability of occurrence of the jackpot mode is 3/1000. When setting is selected, the jackpot mode occurrence probability is 4/1000, when setting is selected, the jackpot mode occurrence probability is 5/1000, and when setting is selected, The probability of occurrence of the big hit mode is 6/1000.

Therefore, the manager of the game hall can arbitrarily select and set the specific game state that appears with the above-mentioned occurrence probability, thereby adjusting the payout rate without performing advanced nail adjustment for the pachinko gaming machine 1. It can be carried out.

Next, a storage box attached to the back of the game board 13

And the rotation of the drum-shaped variable display members 68a to 68c is immediately stopped.

In this embodiment, the probability setting switch 57 does not change the setting probability of the drum-shaped variable display members 68a to 68c, but the setting probability may be changed. . For example, when two drums are stopped, the projector is turned on, and if there is a possibility that three drums will be aligned at this time, when the remaining one drum is rotating, the identification information that will be aligned will be the front side of the game board. Since a predetermined light receiver is momentarily turned on when passing through, the remaining one drum may be stopped at a predetermined timing after the light receiver is turned on. In this case, the contents of the data for determining whether to perform the hit stop control or the disengage stop control can be adjusted on the game card side. For example, in the setting, the number of hit command data; 1
4, the number of command data hits in the setting; 2 the number of command data deviations; 13, the number of specified data hits in the setting; 3 the number of command data deviations; 12, the number of command data hits in the setting; 4 In the setting, the number of hit command data: 5 and the number of deviant command data: 10, and each data may be randomly selected. However, in this case, the data that has been selected once is restored to the original data and is again selected.

Next, referring to the flow charts of FIGS. 8A to 8D,
The operation of the control circuit shown in the figure will be described.

When the control circuit is turned on, the microcomputer
100 initializes all values and waits for the next signal. When the initialization is completed, the microcomputer 100 is processed so that the interrupt routine shown in FIGS. 8A and 8B is always interrupted. This interrupt routine performs the processing of steps S1 to S4 and the processing of steps S5 to S7 based on the signal interrupted by the pulse frequency dividing circuit (interrupt pulse generation circuit) 129 every 4 mS. First,
In Figure 8A, the pachinko ball in the game is the starting winning opening 20
Start by checking whether you have won any of a to 20c Prize winning ball detector
It is determined based on the detection signals of 36a to 36c (step S1),
If one of the starting winning openings 20a to 20c has been won, it is determined whether or not the value of the starting winning storage counter stored in the RAM 103 is "4" (step S2),
If it is not "4", 1 is added to the numerical value stored in the starting winning prize memory counter (step S3) and the LED is displayed.
The start winning award memory indicators 67a to 67d are lit via the circuit 122 (step S4), and the interruption is ended. Meanwhile, step
If there is no detection signal from the starting prize detectors 36a to 36c in S1, and if the numerical value stored in the starting prize storage counter is "4" in step S2, the interruption ends.
Next, in FIG. 8B, it is judged whether or not the probability setting switch 57 of the control board box 50 is turned on (step S
5) If it is turned on, the next time the digital data displayed on the set value display 58b is changed to the next digital data (step S6), the current set value is displayed on the current set value display 58a. The newly set next set value is displayed on the next set display 58b, and the remaining number stored in the variable display number counter is displayed on the variable display number display 59 (step S7), and the interrupt processing is performed. To finish. In addition,
The variable display number counter is decremented by "1" based on the signal after the ball hitting the starting winning openings 20a to 20c and the drum motor 71 of the variable display device 60 is stopped.

On the other hand, returning to the main routine of FIG. 8C and explaining,
After the initialization, the game is started on the pachinko gaming machine 1, and a pachinko ball is driven into the gaming area 15 of the gaming board 13,
Whether or not the value of the starting winning prize memory counter is "0" is determined by the place where the pachinko balls that have been hit are processed by the interrupt routine (step S8). When the value of the starting winning prize memory counter is "0", the next process is not performed until the value is not "0".

On the other hand, if it is determined in step S8 that the value of the start winning award memory counter is not "0", the microcomputer 100 first subtracts 1 from the start winning award memory counter, and correspondingly, the start award memory is reduced. Display 68a-68d
One is turned off (step S9), and then a solenoid excitation signal is applied to the solenoid circuit 119 to set the drum solenoid 8
Turn on (excitation) 7a to 87c (step S10). Furthermore, after the drum solenoids 87a-87c are turned on, in order to completely release the engagement between the ratchet gears 78a-78c of the drum-shaped variable display members 68a-68c and the hook portions 92a-92c of the stop levers 91a-92c. After a lapse of a minute time (about 100 mS) (step S11), the drum rotation control signal and the digital variable display start signal are given to the motor circuit 118 and the digital display drive circuit 123, and the drum motor 71 and the variable display are displayed. 6
6 by rotating and variably driving the drum-shaped variable display member 68a.
~ 68c and variable display 66 variable display is started (step S12). Then, the fact that the display is variable is notified (step S13).

Next, the drum-shaped variable display members 68a to 68c and the variable display
After the variable display of 66 is started, it is determined whether or not the player has pressed the stop switch 9 (step S1).
4) If it is not pressed, the next step S15
At, it is determined whether or not a fixed time (for example, 5 seconds) has elapsed since the start of variable display. If the fixed time has not elapsed, the process returns to step S14. In step S14, the stop switch 9 is pressed, or after a certain time has elapsed from the start of the variable display without pressing the stop switch 9, one of 10 times is randomly selected.
After one time TR _{1 has} elapsed (step S16), the left variable display member 68a is stopped first (step S17). This is done by the microcomputer 100 sending an excitation stop signal to the solenoid circuit 119 to deactivate the drum solenoid 87a. At the same time, the amplifier 12
A voice signal is given to 4 to cause the speaker 8 to generate a voice indicating that the left variable display member 68a has stopped (step S18). After the variable display member 68a on the left is stopped, one time TR ₂ randomly selected from the 10 different times has elapsed (step S19), the drum solenoid
When 87b is turned off and the central variable display member 68b is stopped (step S20), a sound indicating that the central variable display member 68b is stopped is generated (step S20).
S21). In addition, after the variable display member 68b at the center is stopped, 1 is randomly selected from 10 times in the same manner.
After the lapse of one time TR ₃ (step S22), the drum solenoid 87c is turned off to stop the right variable display member 68c (step S23), and a sound indicating that the right variable display member 68c has stopped is generated. Allowed (Step S2
Four). Note that the selection of the minute time TR ₁ described above may be performed when the stop condition is satisfied, or may be performed when the start winning is achieved. Similarly, minute time TR ₂ , TR ₃ and TR ₄ described later
The time may be selected when the stop condition is satisfied, or may be selected when the preceding minute time TR _n-1 (n = 2 to 4) has elapsed.

After the three drum-shaped variable display members 68a to 68c are stopped, a control signal is applied from the microcomputer 100 to the light projecting circuit 117 to turn on the light projecting devices 83a to 83e (step S25). After the light projectors 83a to 83e are turned on, one minute time TR ₄ selected from the six times is passed (step S26). After the minute time TR ₄ has elapsed in step S26, the digital variable display of the variable display 66 is stopped (step S27), and the fact that it has stopped is notified (step S28). After all the drum-shaped variable display members 68a to 68c and the variable display 66 are stopped as described above, the display of the drum-shaped variable display members 68a to 68c is “Zero eyes”.
Then, it is determined whether or not the digital display of the variable display 66 is "7" (step S29). That is, it is determined whether or not a big hit mode is set.

In the step S29, when it is determined that it is not the big hit mode, the rotation of the drum motor 71 is stopped and the projectors 83a to 83c are turned off (step S3
0), "-1" is processed from the value of the variable display number counter (step S31), and then it is determined whether or not the value of the variable display number counter is "0" (step S32),
In the case of "0", the processing is changed to the new next set value set by the probability setting switch 57 (step S3
3) Furthermore, the value of the variable display counter is newly set to "200
It is set to "0" (step S34). Then, after that, the process returns to the first step S8. Further, in the step S32, when the value of the variable display number counter is not "0",
Return to the first step S8.

On the other hand, when it is determined in step S29 that it is the big hit mode, the rotation of the drum motor 71 is stopped and the light projectors 83a to 83c are turned off (step S35) in the same manner as described above. The value of the counter is processed by "-1" (step S36), and then it is judged whether or not the value of the variable display number counter is "0" (step S37). If it is "0", the probability setting is performed. The processing is changed to the new next set value set by the switch 57 (step S38), and the value of the variable display number counter is newly set to "2000" (step S39). Then, after that, the process proceeds to the process shown in FIG. 8D. In addition, the step S3
Even if the value of the variable display number counter is not "0" in 7, the process proceeds to the process shown in FIG. 8D. In this case, if the display mode of the variable display members 68a to 68c and the variable display 66 is not a big hit mode but a predetermined display mode, a value different from a big hit to the player as a small hit state. May be given. Of course, the occurrence probability of the small hit state may be changed.

Next, the operation of the variable winning ball device 16 in the specific game state, that is, when the jackpot is hit, will be described with reference to FIG. 8D. In the step S29, when the microcomputer 100 judges the big hit state, the sound signal is given to the amplifier 124 to generate the sound from the speaker 8 and the ramp signal is given to the lamp circuit 121 to obtain the game effect lamp 2
7a, 27b, 28a, 28b, etc. are blinked or lit to notify the player of the big hit state (step S40).

Then, in order to improve the feeling of intonation of the player by notifying that the big hit state has been reached with sufficient time, after a predetermined time (about 3 to 4 seconds) has elapsed (step S41), the variable winning ball The opening / closing plate 17 of the device 11 is opened (step S42). This is because the microcomputer 100 gives a control signal to the solenoid circuit 120 and the solenoid 33 turns on.
It is done by being N (excited). At this time, 1 is added to the opening number counter that counts the number of times the opening / closing plate 17 is opened, and a timer that controls the time for exciting the solenoid 33 is set. Then, the fact that the opening / closing plate 17 is opened is notified by the speaker 8 or a lamp, and the digital display 66 is displayed via the digital display drive circuit 123.
The number of times of opening is notified to (step S43).

Next, after the opening and closing plate 17 is opened, the variable winning ball device 16
It is determined whether or not a ball that has won a prize has won the specific winning opening 18 (step S44). This is the V winning ball detector 34
Is sent to the microcomputer 100 via the V winning ball detection circuit 114. When the microcomputer 100 determines that there is a detection signal from the V winning ball detector 34, it is determined whether or not the value of the opening / closing counter of the opening / closing plate 17 is "10" (step S45). . When the value of the opening number counter is not 10, it is further determined whether or not the V winning ball detector 34 has already been operated (step S46). This is determined by whether or not the V winning flag is set. V
When the winning flag is not set, the V winning flag is set (step S47), and the next process (step S47)
Proceed to 48). In the step S44, the V winning ball detector 34 is turned on.
If it is determined that the opening number counter of the opening / closing plate 17 is “10” in step S45, and the V winning flag is already set in step S46. If it is determined that the V winning flag is set, the process proceeds to step S48 without setting the V winning flag.

In step S48, the 10-count detector 35 that detects all winning balls in the variable winning ball device 16 is turned on.
Whether or not it is determined. Every time the 10 count detector 35 detects a winning ball, the detection signal is a 10 count detection circuit.
Sent to the microcomputer 100 via 115, RAM 103
"1" is incremented by 1 to the 10-count counter provided therein (step S49). Then, after that, it is determined whether or not the value of the 10-count counter is "10" (step S50). The value of the 10 count counter is "10".
If it is determined that the time is not set, it is further determined whether or not the solenoid timer has finished counting (step
S51), if not completed, the process returns to step S44 and repeats the processing from step S44 to step S51.

On the other hand, if it is determined in step S50 that the value of the 10-count counter is "10", or step S51
If it is determined that the solenoid timer has expired at, the microcomputer 100 determines that the solenoid circuit 120
To the solenoid 33 to turn off (demagnetize) the solenoid 33 (step S52). Therefore, the opening / closing plate 17 of the variable winning ball device 16 shifts from the open state to the closed state. Open / close plate 17
After closing, the microcomputer 100 allows a predetermined V reception waiting time to elapse (step S53). This is because the last ball that won the opening and closing plate 17 is the specific winning opening 18
This is because there is a time margin until the V winning detector 34 is activated after passing through. And after that waiting time,
Whether or not the V winning flag is set, that is, when the opening / closing plate 17 is opened, or when the opening / closing plate 17 is closed and before the V reception waiting time elapses, the effective winning of the specific winning opening 18 is confirmed. It is determined whether or not there is (step S54). If it is determined that the V winning flag is set, 10
The stored contents of the count counter and the V winning flag are cleared (step S55), the process returns to step S42, and the opening state of the opening / closing plate 17 is repeated for a certain time or until a predetermined number of winning balls are generated.

On the other hand, if it is determined in step S54 that the V winning flag is not set, the stored contents of the 10-count counter and the number-of-opening counter are cleared (step S56), and the process returns to the first step S8 and thereafter. Repeat the process.

As is clear from the above description of the operation, in this embodiment (first embodiment), by operating the probability setting switch 57 according to the intention of the game arcade, among the predetermined plural kinds of occurrence probabilities. Since one of them can be selected and set, it is possible to easily adjust the payout rate without resorting to nail adjustment, which requires high technology. Also, the change is not immediately reflected in the game even if the probability setting switch 57 is operated, and after the number of remaining winnings of the starting winning opening 20a to 20c displayed on the variable display number display 59 at the time of setting has elapsed. If it is not changed, there is an effect that the game hall side cannot perform an operation that causes the player to feel distrust, and the clerk of the game hall cannot perform cheating.

Is connected to the drive control board 157 by wiring.
The drive control board 157 has mounting holes 158a, 158b formed on the upper and lower sides of the drive control board 157, and mounting bosses 156a-156 are formed on the rear surface side of the drive unit storage box 142.
Some mounting bosses 156a, 15 of d (however, 156d is not shown)
6d is penetrated and supported, and the other side is tightly fixed to the rear surface of the drive unit storage box 142 by fastening with screws.

The mounting terminal bosses 156a to 156d are connected to the relay terminal board 16
1 is fixed. This relay terminal board 161 relays the wiring from the electrical parts provided in the entire variable display device 130, and the drive control board connection connectors 162a, 162 described above.
62b and motor connection connectors 163a to 163c are provided, a relay terminal board connection connector (not shown) for connecting to an external power source is provided, and the power supply connection connector for external wiring is connected to the relay terminal board connection connector.

The operation of the variable display device 130 having the above-described structure will be described with reference to FIGS. 10 and 11. First, a ball is inserted into the starting winning openings 20a to 20c and the starting switches 36a to 36c.
Is turned on (step S1), and when turned on, the randomly fetched data RD1 to RD3 are confirmed (steps S2, S2 ', S2 "). This data RD1 to RD3
Correspond to SP1 to SP3 motors respectively. The data RD1 to RD3 are also data for identifying the identification information to be displayed on the rotary drums 144a to 144c. Therefore, in this operation example, the combination of the identification information displayed on the rotary drums 144a to 144c is determined at the time when the ball hitting the starting winning openings 20a to 20c. The data
The method of selecting RD1 to RD3 will be described later in detail.

The following process is the same for each SP motor.
The processing procedure of the motor will be described. After the data RD1 is confirmed, the SP1 motor is driven (step S3).
When driving this SP1 motor, a signal with a large pulse width is given first and a signal with a small pulse width is given gradually so as to gradually increase the rotation speed. This is done because the starting torque of the SP1 motor is small. Also, when the SP1 motor is stopped, it is preferable that the SP1 motor is stopped so that the rotation speed is gradually reduced. This is because if stopped suddenly, the inertia of the drum becomes larger than the magnetic attraction, and the drum may rotate extra.

After the driving of the SP1 motor is started, it is judged whether or not the sensor 1 is turned on (step S4), and when it is turned on, the step counter SC1 is reset (step S5) and the step counter SC1 is started to be counted. (Step S6).

After the counting of the step counter SC1 is started, it is judged whether or not there is a stop command signal by the stop switch 9 or the timer (step S7). When there is a stop command signal, the value of the step counter SC1 and the data RD1 are judged. It is determined whether or not the values are the same (step S8). Then, when the values become the same, the SP1 motor is stopped (step S9). At this time, the identification information displayed on the rotary drum 144a is the identification information determined corresponding to the data RD1.

The processing in steps S3 to S9 is the same as steps S3 'to S9' and steps S3 "to S9" in the SP2 and SP3 motors, and the data RD2, R is stored in the rotary drums 144b and 144c.
The identification information corresponding to D3 is displayed.

By the way, in order to select the data RD1 to RD3,
For example, the method shown in FIG. 11 is used. That is, one cycle of data (for example, 2000 times)
Is divided into 5 blocks, one of which is further divided into 4 sub-blocks. Next, any one of the blocks and the sub-blocks is randomly combined to create data for 500 times. Then, data is sequentially selected for each variable display from the created data for 500 times (at the time of winning a prize), and if the selected data is big hit data, it may be stopped in the big hit display mode. If it is data, the data RD1 to RD3 are fixed so that it is stopped in a display mode other than the big hit. In addition,
It is preferable not to return the data once selected to the data for 500 times, but it may be returned.

On the other hand, when all the data for 500 times are selected (when the variable display is performed 500 times), any one of the remaining three sub-blocks except the sub-block combined with the block is randomly selected as a block. Combine and create the data for the next 500 times. Below, combine the block and one of the remaining two sub-blocks to create the data for the next 500 times, and then combine the block and the remaining sub-block to create the data for the next 500 times. When all the data is created and selected, one cycle ends and the process returns to the block. By the way, if five cycles are prepared in which the number of big hits in one cycle is different, and the probability can be arbitrarily selected from among the five cycles by operating the probability setting switch 57, the occurrence probability of the big hit mode can be obtained. Can be changed. For example, the eleventh
As shown in the figure, the setting should include 6 jackpots in one cycle, the setting should include 8 jackpots in one cycle, and the setting should include 9 jackpots in one cycle. , The setting includes 10 jackpots in one cycle, and the setting includes 12 jackpots in one cycle.
It suffices that the setting be made by the operation of 57. However, at the end of one cycle, if the next set value is the same as the current set value, the block corresponding to the same set probability again (however, the sub-blocks combined at that time are randomly selected, so It is not always combined with the same sub-block), and the above-mentioned control for one cycle is performed, and if different, the control for one cycle is performed from the block for the setting probability corresponding to the next setting value.

As a matter of course, the setting probability does not change at the time when the probability setting switch 57 is operated, and is changed when the above-mentioned one cycle (variable display of 2000 times) ends. .

The method shown in FIGS. 12 to 14 may be used to select the data RD1 to RD3 of the variable display device 130.
First, the method shown in FIG. 12 will be described. In the control circuit, a second variable display number counter that is reset each time a big hit display state (hereinafter, referred to as a specific display state) occurs is provided. If the specific display state does not occur until the value of the display count counter reaches the predetermined value (from the occurrence of the previous specific display state to the variable display count reaches the predetermined number), at the time of the variable display of the predetermined number of times. The data RD1 to RD3 are confirmed so that the specific display state is achieved. For example, as shown in FIG. 12, when the variable display count has reached 500 times since the occurrence of the previous specific display state, but the specific display state has not been reached during that time, the variable display for the 500th time is displayed. RD1 to R for combination data that sometimes becomes a specific display state
Give it to D3 to force the specific game state to appear. Then, if the predetermined value described above, that is, the maximum variable display count for achieving the specific display state is made different according to the setting content and the setting content can be arbitrarily selected by the probability setting switch 57, the specific game state The occurrence probability of can be changed. For example, as shown in FIG. 12, in the setting, the predetermined value is set to 500, in the setting, the predetermined value is set to 400, and in the setting, the predetermined value is 3
Is set to 00, in the setting the predetermined value is set to 250,
In the setting, the predetermined value is set to 200. The variable display control until reaching the predetermined value is controlled based on a certain probability.

In addition to the method shown in FIG. 12, the method shown in FIG. 13 uses data RD1 so that the specific display state does not occur until the value of the second variable display number counter reaches the second predetermined value.
Control to confirm ~ RD3 is added. Therefore, in this case, control is performed such that the next specific display state occurs in the variable display between the minimum variable display number and the maximum variable display number for achieving the specific display state. Then, if the minimum variable display number and the maximum variable display number for achieving the specific display state are made different according to the setting content and the setting content can be arbitrarily selected by the probability setting switch 57, the specific game state The occurrence probability of can be changed. For example, as shown in FIG. 13, in the setting, the minimum variable display number (second predetermined value) is set to 101, and the maximum variable display number (predetermined value) is set to 400.
The second predetermined value is set to 76 and the predetermined value is set to 350. In the setting, the second predetermined value is set to 51 and the predetermined value is set to 300. In the setting, the second predetermined value is set to 26. ,
The predetermined value is set to 250, and the second predetermined value is set to 1 and the predetermined value is set to 200 in the setting. Note that the variable display control from the second predetermined value to the predetermined value is controlled based on a certain probability.

Further, in addition to the method shown in FIG. 13, the method shown in FIG. 14 has both predetermined values as shown in FIG. 14 (A) (the minimum variable display number and the maximum variable display number for the specific display state). )
5 patterns to are prepared in advance are prepared, and 10 patterns are arbitrarily gathered to create a pattern. Then, one pattern is randomly selected from the 10 patterns each time the specific display state occurs, and control is performed based on the pattern. Then, the above 5
When 10 patterns ~ are gathered together, if the combination of patterns is changed according to the setting and the setting contents can be arbitrarily selected by the probability setting switch 57, the probability of occurrence of a specific game state can be changed. it can. For example, as shown in FIG. 14 (B), it is created so as to include many patterns and the like that increase the probability of occurrence of the specific display state as the setting proceeds. Note that also in this case, the variable display control from the second predetermined value to the predetermined value is controlled based on a certain probability.

Further, in order to select the data RD1 to RD3 of the variable display device 130, it is not based on the method shown in FIG. 11 and FIG. 14 described above, but based on the probability controlled by an ordinary electronic random number generating means. You may In this case, a plurality of different probabilities depending on the settings may be prepared.

As is clear from the above description of the operation, also in this embodiment (second embodiment), by operating the probability setting switch 57 according to the intention of the game arcade, among the predetermined plural kinds of occurrence probabilities. Since one of them can be selected and set, it is possible to easily adjust the payout rate without resorting to nail adjustment, which requires high technology. Further, the change is not immediately reflected in the game even if the probability setting switch 57 is operated, and is not changed until after the number of remaining times (variable display number) of one cycle at the time of setting is changed, so on the game side. Also, there is an effect that an operation that causes a distrust of the player and an illegal act of a clerk at the game hall cannot be performed.

The case where the method according to FIGS. 12 to 14 described above is applied to the variable display device 130 of the second embodiment has been described, but this method is also applied to the variable display device 60 of the first embodiment. good. In this case, until the variable display count reaches the minimum variable display count, or after reaching the maximum variable display count, the control for turning on the above-mentioned projector at the time when the two drums are stopped (there is a possibility that there are three If so, when the remaining one drum is rotating, when the identification information to be aligned passes through the front of the game board, a predetermined light receiver is momentarily turned on. Therefore, this light receiver is After turning it on, the control is switched to control for stopping the remaining one drum at a predetermined timing. After the variable display count reaches the minimum variable display count, stop control of the remaining one drum is performed so as to be off until the variable display count reaches the minimum variable display count.

In the embodiment described above, the variable display device 60,
Although the 130 and the variable winning ball device 16 are provided separately, they may be provided integrally, and the configurations of the variable winning ball device 16 and the variable display devices 60, 130 are not limited to those shown in the figures. . For example, as a variable winning ball device, an opening / closing plate 17
It is also possible to use a pair of opening and closing blades or sliding pieces instead of the LCD, EL, roulette type, leaf type, belt type, instead of a drum type variable display member as a variable display device.
It is also possible to use a dot display device or other display device. Further, the stop switch 9 for stopping the variable display of the variable display devices 60, 130 may be omitted and only the automatic stop may be performed by the timer. Further, the stop order is not limited to the embodiment. Furthermore, the variable display member (including the rotating drum) and the variable display of the variable display may be configured to be started when the power is turned on, and to be variably started again by a winning start. In this case, it is preferable to switch the brightness of the variable display of the variable display member or the variable display or to change the speed of the variable display in order to clarify that the variable start is started by the winning a prize. Further, the variable display member and the variable display of the variable display off may be variably displayed in the normal state so as to be stopped by the start winning.

As a condition for changing the occurrence probability of the specific game state, the variable display number is set in the above-mentioned two embodiments, but various factors that function in the game can be selected. For example, when a certain time (for example, 24 hours) has elapsed, when the number of times of a specific game state reaches a predetermined number, when the number of out balls reaches a predetermined number, and so on.

Further, as the specific game state, the state in which the variable winning ball device can be opened under a predetermined condition is illustrated, but the condition that the variable winning ball device can be repeatedly opened, that is, the so-called V continuation condition is adjusted by, for example, a variable display. As long as it is configured to be possible, the V continuation may be defined as a specific game state and the continuation rate may be adjusted. Furthermore,
The range or step in which the occurrence probability can be adjusted is not limited to the above-mentioned embodiment, and the adjustment direction does not change the switch by pressing, but may be one that can be set by a complicated operation. Further, the setting means may be provided not in the ball game machine but in the central control room of the game hall so that it can be operated remotely. Furthermore, the game content may be any as long as the probability of occurrence of the specific game state can be adjusted on the game hall side. In addition, as the game value given by the occurrence of the specific game state, a certain number of prize balls are paid out due to the occurrence of the specific game state, or in the following card type ball game machine, a predetermined score May be given.

Further, in the above-described embodiment, as a ball game machine,
