The winning prize flowing down substantially at the center of the prize is highly likely to be the winning prize ball stored in the storage section 32 and released. Therefore, in order to enter the specific game state or to establish the continuation right, it is necessary that the winning balls received by the ball receiving members 25a and 25b be stored in the storage unit 32, as described above. Since a storage state appears during the opening / closing cycle, it is only necessary that the winning prize be stored during the storage state.

Although the structure of the variable winning ball device 20 in the winning space 23 is generally the same as that described above, the variable winning ball device 20 includes a number of accessory lamps 45 (not shown).
And a decorative LED 46 (not shown; however, shown in the block diagram of FIG. 3).

The configuration of the gaming board 1 of the pachinko gaming machine including the variable winning ball device 20 has been described above. The gaming machine provided on the gaming board 1 is controlled by a game control circuit shown in FIG. FIG. 3 is a circuit diagram showing a block diagram of a game control circuit formed on the control board, which is controlled by a basic circuit 50 including an MPU, a ROM, a RAM, and an input / output circuit. Thus, the basic circuit 50

a, 7b, specific winning ball detector 40, winning ball detector 30
a, 30b, a photo sensor 44, and a detection signal from a setting switch 62 for changing a probability, which will be described in detail later, are inputted, and a chip select signal is supplied from an address decode circuit 52 to a basic circuit 50 and a switch circuit 51. When the power is turned on, the initial reset circuit 53 outputs the basic circuit 5.
A reset signal is provided to 0, and a periodic reset signal is provided from the periodic reset circuit 54 to the basic circuit 50 at predetermined time intervals.

On the other hand, a control signal is supplied from the basic circuit 50 to the following devices and circuits. That is, the motor circuit 55
A drive signal is given to the movable motor 42 and the decoration motor 43 through the
7, a display control signal is given to the winning number display 28 and the decoration LED 46, and a drive signal is given to the ball receiving member solenoids 26a and 26b via a solenoid circuit 57. In addition, the shoulder lamps 10a, 1
0b, sleeve lamps 11a, 11b, windmill lamps 12a, 1
A display control signal is sent to 2b, side lamps 13a and 13b, rail decoration lamp 14, game effect lamp 16, and accessory lamp 45. Further, a sound signal is given to a speaker via a sound circuit 59, and a driving signal is output to an information output circuit 60 for deriving a big hit signal and an effective start winning signal. Note that power having various voltages is supplied from the power supply circuit 61 to the above-described devices and circuits.

Next, the operation of the variable winning ball device 20 controlled by the basic circuit 50 described above will be described with reference to FIGS. FIG. 4 shows the symbols displayed on the number-of-openings indicator 27 variably displayed when the specific winning ball detector 40 is turned on when a winning ball at the time of starting winning is turned on, the number of continuations, and the probability of appearance of the number of continuations. FIG. 5 is a timing chart showing a state in which the probability of a big hit game state fluctuates.

In FIG. 4, the ball receiving members 25a and 25b of the variable prize ball device 20 perform opening and closing operations once or twice by the start winning, and the winning balls received during the opening and closing operations are guided to the specific winning area 38. When the special winning ball detector 40 is turned ON, a jackpot game state occurs, the opening number indicator 27 fluctuates, and stops after a certain period of time. When the symbol at the time of the stop is "7", the number of continuations is determined to be "16", and when the symbol to be stopped is "F", the number of continuations is determined to be "8". When it is “3”, the number of continuations is determined to be “3” times, and when the stop symbol is other than the above, the number of continuations is determined to be “2” times. Then
The probability that each symbol appears is determined by the setting switch 6
It differs depending on the setting of 2. That is, FIG.
When the setting switch 62 is set to “1”, the probability that the symbols “7”, “F” and “3” appear is 5/55, respectively, and other symbols appear. The probability of performing is 40/55. The setting switch 62
Is set to “2”, the symbols “7” and “F”
The probability that “3” appears is 4/55, and the probability that other symbols appear is 43/55. Further, when the setting switch 62 is set to “3”, the probability of appearance of the symbols “7”, “F”, and “3” is 3/55, and the probability of appearance of other symbols is 3/55. ,
46/55.

As described above, the number of continuations is set to be different depending on the symbol displayed when the big hit game state occurs, and the appearance probability of the symbol is set by the setting switch 6.
Since the setting can be changed by setting 2, the payout rate in the specific gaming state can be changed, and the change can be set so as to surely lower or raise the payout rate. The ball rate can be brought close to a desired value, which makes the technically difficult starting winning openings 4, 5
A desired payout rate can be obtained even if the adjustment of the obstacle nails in the vicinity of the a and 5b and the ball receiving members 25a and 25b is somewhat rough.

In this embodiment, when the first big hitting game state is completed as shown in FIG. 5, the symbol "7" corresponding to the maximum number of times of continuation until the time T1 elapses from the end point. Is a high probability state in which the appearance probability of is greatly improved. For example, as shown in FIG. 4, the appearance probability of the symbol “7” is 50/50 regardless of the setting value of the setting switch 62.
55. Therefore, if the next big hit gaming state occurs within the T1 time, the next big hit gaming state is:
There is a high possibility that the jackpot game state will be reached with the maximum number of continuations. In the embodiment of FIG. 5, the time T1 is shown as a time interval before the second big hitting game state occurs.
The time T1 may be set to the time when the next big hit game state occurs. The timing at which the probability becomes high and the timing at which the probability returns from the high probability to the low probability may be arbitrarily designed.
Furthermore, even at the time of the high probability, the appearance probability of the symbol corresponding to the maximum continuation number may be set to be different depending on the value of the setting switch 62.

In the above description, the number of continuations is different depending on the symbol, but the number of continuations is the same (for example, 16
), And the number of winning balls allowed during one opening / closing cycle may be changed depending on the symbol. For example,
The number may be ten for the symbol "7", eight for the symbol "F", five for the symbol "3", and three for the other symbols. Also in this case, the payout rate in the specific gaming state can be changed, and the change can be set so as to surely lower or raise the payout rate. , So that a desired payout rate can be obtained even if the adjustment of the obstacles near the starting winning prize holes 4, 5a, 5b and the ball receiving members 25a, 25b is technically difficult. . Similarly, the number of opening and closing operations of the ball receiving members 25a and 25b in one opening and closing cycle may be changed.

In the above description, the number of open / close cycles or the number of winnings in the big hit game state is determined by the display result of the variable display device, and the desired payout ratio is set by changing the derivation probability of the display result. Although what can be obtained is shown, the ball receiving member 25 at the time of the starting prize is shown.
The same object as described above can be achieved by changing and setting the winning rate of the winning prize in the open state of a or 25b once or twice. Such an embodiment will be described with reference to FIGS. FIG. 6 shows a setting switch 62.
FIG. 7 shows the ball receiving members 25a and 25 controlled by the set winning rate.
It is a flowchart which shows the operation subroutine of b. Here, the winning rate in the present embodiment is a ratio of the winning number of hit balls to the ball receiving members 25a, 25b to the effective starting winning (starting winning in which the ball receiving members 25a, 25b are actually operated).

In FIG. 7, in step 10, the ball receiving member 2
It is determined whether or not 5a, 25b (hereinafter referred to as "accessories") has been started. If not, the subroutine is terminated. If started, the start number counter is updated in step 20. Since the starting number counter is updated when the accessory is started in this way, the effective starting winning is counted.
Thereafter, it is determined in step 30 whether or not a hit ball has been won in the role. If there is no prize, the process skips to the next step 40 and proceeds to step 50. If there is a prize, the process proceeds to step 40. Update the winning ball counter. The bonus prize ball number counter counts the number of prize balls that are actually received by the ball receiving members 25a, 25b and detected by the prize ball detectors 30a, 30b by the opening / closing operation based on the starting prize. Thus, after the processing in step 40, in step 50, the bonus winning rate is calculated.
This prize winning rate is based on the value of the start counter as a denominator,
The value of the number of the winning prize ball counter is obtained as a numerator.

At step 60, it is determined whether or not the thus determined bonus prize rate is smaller than the prize rate set by the setting switch 62. Setting switch 62
As shown in FIG. 6, the winning rate set in the case of setting 1 is "1.00" in the case of setting 1, and the winning rate is "0.75" in the case of setting 2. In the case of the setting 3, the winning rate is “0.50”. That is, the winning rate “1.00” is set to 100 every time there is an effective starting prize.
% Of the ball is won, and the winning rate is "0.7
The setting of "5" means that a hit ball wins with a probability of 75% each time there is an effective start prize, and the setting of the winning rate "0.50" sets a probability of 50% every time there is an effective start prize. The hit ball is to win. If it is determined in step 60 that the bonus winning rate is smaller than the set winning rate, it is determined in step 70 whether or not the bonus operation time is shorter than the maximum 0.9 seconds. Then, in step 90, the value of the accessory operation time is increased by 0.1 second to increase the accessory winning rate, and the subroutine is terminated.

On the other hand, if it is determined in the step 60 that the bonus winning rate is not smaller than the set winning rate, it is determined in a step 90 whether the bonus winning rate is larger than the set winning rate. If determined, step 1
At 00, it is determined whether or not the accessory operation time is longer than the minimum 0.5 second. If it is larger, the value of the accessory operation time is reduced by 0.1 second at step 110 in order to reduce the bonus winning rate. End the subroutine. If the value of the winning prize rate calculated in step 50 is the same as the set prize rate, step 6
Since it is determined as “NO” at 0 and 90, no change of the accessory operation time is performed.

In the above-described operations from step 10 to step 110, the opening time of the one or two times of the accessory at the time of the starting prize is always finely adjusted between 0.5 seconds and 0.9 seconds. The winning rate of the ball hitting the character with respect to the effective starting winning is brought close to the winning rate set by the setting switch 62, whereby the probability that the winning ball is guided to the specific winning area 38 is increased according to the set value, or Or it can be reduced. This indirectly sets the occurrence rate of the jackpot game state itself to a desired value. Therefore, the adjustment of the obstacle nail near the ball receiving members 25a and 25b and the vicinity of the starting winning openings 4, 5a and 5b are performed. Even if the adjustment of the obstacle nail is somewhat loose, a desired payout rate can be obtained as a whole. It should be noted that, instead of comparing the winning rate of a ball hitting the character with respect to the effective starting prize to the set winning rate, the winning rate of a ball hitting the character with respect to the total starting prize may be compared with the set winning rate. good.

In the above-described embodiment, an example has been described in which the winning object set with the winning rate is the ball receiving members 25a, 25b. However, as shown in FIG. 8, a pair of opening / closing members 73a, The electric start winning opening 72 driven to be opened and closed by a solenoid (not shown) may be configured as the starting winning opening 73b, and this may be regarded as an accessory. In this case,
The passage of the hit ball to the passage 70 is detected by the passing switch 71, and based on the detection, the opening / closing members 73 a and 73 b are opened for a very short time, and the winning prize ball received during the opening is detected by the starting prize ball detector 74. By detecting, it is possible to detect the number of effective passages and the number of hit balls hitting the electric start winning port 72 as an accessory. Thus, the role shown in FIG. 7 is set as the electric starting winning port 72, and the operation shown in FIG. 7 is performed by replacing the starting number counter with a passing number counter that counts the effective passage of the hit ball to the passing port 70. As a result, the winning rate of the hit ball to the electric start winning port 72 is brought close to the set winning rate set by the setting switch 62, thereby increasing the probability that the hit ball is guided to the variable winning ball apparatus 20 according to the set value. Or it can be reduced.
This means that the occurrence rate of the big hit game state itself is indirectly set to a desired value.
a, adjustment of obstacle nail near 25b and electric start winning port 72
Even if the neighboring nails are slightly adjusted, a desired payout rate can be obtained as a whole. In FIG. 8, the winning openings 5a and 5b arranged on the left and right of the electric starting winning opening 72, respectively.
May be configured as a normal winning opening.

In the above-described embodiment, the variable display device that also serves as the opening number display 27 is shown, but a dedicated variable display device may be used. In addition, it is only necessary to arbitrarily set a plurality of stages of sections by the change setting means, and the invention is not limited to three stages as in the embodiment.

[0033]

As is apparent from the above description, in the invention according to the first aspect, the number of times of repeating the first state of the ball receiving member in the second mode in the specific game state is the number of times the ball receiving member is continued. Since the number of possible times is determined based on the determination result of the variable display device, the amount of prize balls that can be obtained even in the specific game state is different for each specific game state, and when a predetermined condition is satisfied, the maximum Since the probability of deriving the display result that is the number of continuations is improved, the chance of acquiring a large number of prize balls also increases, and the interest of the player can be attracted. Furthermore, since the probability of deriving the display result having the maximum number of times of continuation can be changed and set in a plurality of stages, it is possible to adjust to a desired payout rate.
