DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention improves the probability of displaying one of the big hit symbol combinations on a symbol display device when a predetermined big hit symbol combination is obtained from a plurality of big hit symbol combinations. The present invention relates to a pachinko machine that is controlled to perform pachinko machines.

[0002]

2. Description of the Related Art Conventionally, when a combination of big hit symbols is displayed on a symbol display device, a big hit game state is established and a variable winning device is set in a predetermined mode (for example, until a predetermined time elapses, or a predetermined number of prizes are won). Until the ball occurs)
Based on the fact that a winning ball has won a continuous winning opening (also referred to as a V winning opening) formed in the variable winning device during the opening, a continuation right to reserve the next opening of the variable winning device is established. A large number of pachinko machines have been provided on the market that allow the continuation right to be established a predetermined number of times and repeatedly open the variable winning device in a short time. In such pachinko machines, those in which the probability that the combination of big hit symbols is displayed are dominant have been dominant, but in recent years, those that change the probability have been provided.

[0003]

In a pachinko machine in which such a probability is changed, one or three predetermined combinations of jackpot symbols are selected from among a plurality of combinations of jackpot symbols. Was changed to a high probability when was displayed, and the occurrence cycle of the next big hit gaming state was shortened to attract the interest of the player, but such a change condition is higher than the appearance probability of the big hit symbol At a low probability, and the probability cannot be changed unless a certain amount of time has passed since the opening of the store. Was. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a pachinko machine in which a probability change at the time of opening a store is highly likely to be executed.

[0004]

In order to achieve the above-mentioned object, according to the present invention, when a combination of a plurality of big hit symbols becomes a predetermined combination of big hit symbols, a symbol display device is provided. In a pachinko machine that is controlled so that the probability of displaying the combination of the jackpot symbols is improved, the number of hit balls or the number of power sources from the time of turning on the power to the starting winning opening that allows the variable display of the symbol display device. When the variation number of the symbol display device from is within a predetermined value, even when it becomes a predetermined symbol combination other than the predetermined jackpot symbol combination, the probability of displaying the combination of the big hit symbol The present invention is characterized in that a probability improving means for improving is provided.

[0005]

When the symbol displayed on the symbol display device is a combination other than the predetermined jackpot symbol combination, if the symbol combination is a predetermined symbol combination, the displayed symbol combination is turned on when the power is turned on, that is, the store is opened. If the number of start winnings or the number of changes from time is within a predetermined value, the probability is changed to a high probability. As the combination of the predetermined symbols, for example, a combination of all of the plurality of jackpot symbols or a combination including only a specific symbol can be considered. In any case, according to the present invention, when a symbol combination that appears relatively more frequently than before appears within a predetermined period from the power-on at the time of opening the store, the probability is changed to a high probability. The atmosphere of the amusement arcade.

The variable winning device 20 provided substantially at the center of the game area 3 has a mounting board 21 mounted on the surface of the game board 1, and a normal winning opening 22 is formed at the top of the mounting board 21. Have been. The hit ball that has won the winning opening 22 is guided to the back of the gaming board 1 and is processed as a normal winning ball. In addition, below the winning opening 22, a rectangular hitting ball entrance 23 is opened and the hitting ball entrance 23 is formed.
A guide projection 24 is provided along the lower edge of the projection. For this reason, the hit ball that has flown from the left and right sides of the game area 3 is received by the guide protrusion 24 and is taken into the hit ball entrance 23. The hit ball taken into the hit ball entrance 23 passes through the side of the variable winning device 20 and is discharged again to the front side of the game board 1 from the drop hole 26 formed at the lower portion of the variable winning device 20. I have.

The above-mentioned guide projection 24 is projected substantially in a rectangular shape except for the lower portion, and a symbol display device 25 is provided so as to be surrounded by the guide projection 24. In the present embodiment, the symbol display device 25 is configured by three dot matrix LEDs, and each dot matrix LED displays 15 symbols (for example, numerals from 0 to 9 and English characters from A to E). It can be displayed.
When a ball is hit in any of the start winning ports 4a to 4c, the dot matrix L of the symbol display device 25 is displayed.
The ED starts scrolling at a speed that cannot be visually recognized by the player, and after a lapse of a predetermined time (for example, 5 seconds), the fluctuation display is stopped and three symbols are stopped and displayed. When the combination of symbols stopped and displayed is a combination of big hit symbols, a big hit game state is set. The combination of the jackpot symbols is a case where the same symbol is displayed on three dot matrix LEDs. Therefore, the combination of the jackpot symbols is

Then, when the combination of the predetermined big hit symbols (for example, the 3rd, 7th, 9th, etc.) becomes a predetermined big hit symbol combination during the normal game out of the 15 big hit symbol combinations, The probability that a big hit symbol is displayed when the value changes is high (for example, 1/25)
Is set to change. Note that the normal probability before being changed to the high probability (hereinafter referred to as the low probability) is, for example, 1/250
Is set to

[0010] When the big hitting game state is reached, the opening and closing members 27a and 27b pivotally supported substantially at the center and left and right of the mounting board 21 are opened for a predetermined time (for example, 30 seconds). However, if the number of winning balls received by the open / close members 27a, 27b during opening is ten, the open / close members 27a, 27b are closed even before a certain time has elapsed. In addition,
The open / close members 27a and 27b are connected to a solenoid 28 (not shown; however, shown in the block diagram of FIG. 4) via a link member (not shown) so that the open / close members 27a and 27b are opened when the solenoid 28 is excited. It has become.

The hit ball received by the opening / closing members 27a and 27b rolls rearward in the winning space 29 formed substantially at the center of the mounting board 21. Behind the winning space 29,
Three fall openings for the winning ball to fall downward are formed, the center of which is a V winning opening 30 as a continuous winning opening, and the left and right are normal winning openings. V winning opening 30
A winning ball detection switch 31 (not shown; however, shown in the block diagram of FIG. 4) faces and detects a hit ball that has won the V winning opening 30. V winning ball detection switch 3
When 1 is turned on, the open / close members 27a and 27b are repeatedly opened for a certain period of time. That is, when the big hit game state is set, the opening and closing member 27
The winning prize ball accepted by the opening of the a and 27b wins the V winning opening 30 to establish the continuation right, and the variable prize winning device 20 corresponds to the number of times the continuation right is established.
Is repeatedly performed, so that a large amount of winning balls are generated in a short time. However, the number of repetitions described above is set to a maximum of 16 times on condition that a hit ball is hit into the V winning opening 30.

In order to count the number of hit balls received by the opening / closing members 27a and 27b, a winning ball number detection switch 32 (not shown; however, a block diagram of FIG. Is displayed). The winning ball number detection switch 32 wins not only the winning ball guided to the winning space 29 and won in the V winning opening 30 but also the normal winning opening formed on the left and right sides of the V winning opening 30. It is arranged at a position where a winning ball can be detected. The winning ball that has passed through the winning ball number detection switch 32 flows down along the back surface of the game board 1 and is processed as a winning ball.

In addition to the above-mentioned configuration, the variable winning device 20 has a start memory lamp for notifying that the hit ball has been stored in the starting winning ports 4a to 4c at the time of the big hit game state or the variable display of the symbol display device 25. 33 (symbol display device 25
Located below).

The game operation of the pachinko machine 1 is controlled by a control circuit formed on a control circuit board housed in a control circuit board box (not shown). The control circuit is shown in FIG. . FIG. 4 is a block diagram of the control circuit. The control circuit uses a microcomputer 50 as a control center. The microcomputer 50 has an external ROM 51, an external RAM 52
Is connected.

On the other hand, start winning ball detection switches 15a-15c for detecting winning balls in the start winning ports 4a-4c,
A V-prize ball detection switch 31 for detecting a prize ball in the V-prize port 30 and a prize-ball number detection switch 32 for detecting a prize ball received by the opening / closing members 27a and 27b are transmitted to the microcomputer 50 via a waveform shaping circuit 53. It is connected. The clock generation circuit 55 outputs an external interrupt signal to the INT terminal of the microcomputer 50 via the frequency divider 54. When power is supplied to the power supply circuit 57, the reset signal generation circuit 56 outputs a reset signal. The reset signal is supplied to the microcomputer 5
0 is input to the RST1 terminal, and an initial program (not shown) is started.

A display drive circuit 58, a display selection circuit 59, and a driver 60 are connected to each output port of the microcomputer 50. The symbol display device 25 and the starting memory lamp 33 are connected to the display drive circuit 58 and the display selection circuit 59. These displays are dynamically driven by outputting selected data and display data from the microcomputer 50 at regular intervals. That is, each display unit is selected by the display selection circuit 59 and displayed according to the output signal of the display drive circuit 58 at that time. The driver 60 operates in response to a signal from the microcomputer 50 to drive the open / close solenoid 28, the big hit lamps 11a and 11b, the operation lamps 13a and
Lighting operations of 13b, 14a, 14b, etc. are controlled respectively.

Next, of the game operations controlled by the above-described control circuit, an example of the probability improving process will be described with reference to the flowcharts of FIGS. First, as shown in FIG. 2, it is determined whether or not the start winning ball detection switch 33 has been turned on in step 110. If not, the start winning subroutine ends.
When it is determined in step 120 that the start storage counter C1
Is determined to be smaller than 4, and if it is smaller, the value of the start storage counter C1 is updated at step 130 by one. The start storage counter C1 is for allowing the symbol display device 25 to fluctuate, and when the value is 1 or more, the symbol display device 25 starts to fluctuate by a fluctuation routine (not shown). At the same time as the start of the fluctuation, the value of the start storage counter C1 is decremented by one. After the processing in steps 120 and 130 described above, in step 140, the value of the starting integration counter C2 is updated by one. The start accumulating counter C2 is provided with a start winning port 4a from power-on.
This is to count the number of winning balls hitting 4c.

Next, the probability improving subroutine shown in FIG. 1 will be described. At step 10, it is determined whether or not a big hit has occurred, and if not, the probability improving subroutine ends. If it is a big hit, it is determined in step 20 whether or not the value of the starting integration counter C2 is smaller than 51. When the value of the start integration counter C2 is greater than 51, it is considered that a predetermined period has elapsed since the power was turned on at the time of opening the store, and the jackpot determined in step 10 in step 30 is "3" or "7" or "9". It is determined whether or not any one of the two eyes is the one. If not, the probability improvement subroutine ends. On the other hand, when it is determined in step 20 that the value of the starting integration counter C2 is smaller than 51, or in step 30, it is determined that the big hit is any one of "3", "7", or "9". At times, a high probability flag is set in step 40. As a result, the cycle in which the big hit symbol appears in the subsequent fluctuations is shortened. The change of the probability is set based on the flag described above in a probability change subroutine (not shown).

As described above, in this embodiment, any combination of big hit symbols can be selected from when the power is turned on at the time of opening the store until the winning number of hit balls in the starting winning openings 4a to 4c reaches 50. Regardless of the big hit, the probability is improved, so that the atmosphere of the game hall at the time of opening the store can be excited. In addition, the starting winning opening 4a from the time of power-on.
When the number of winning balls hitting 4c exceeds 50, the time has elapsed since the store opened, and the condition for changing to the high probability is set to the normal state. The transition from the high probability to the low probability may be shifted to the low probability based on the occurrence of the first big hit, or based on the occurrence of the second big hit or the occurrence of the big hit more times. You may make it shift to a low probability.

In the above-described embodiment, the condition for improving the probability at the time of turning on the power has been described as being all combinations of the big hit symbols. However, other conditions, for example, the combination of the symbols displayed at the time of stoppage are specified. It is good also as a condition whether it is constituted only from a design. FIG. 3 shows an example of an operation under such conditions. Hereinafter, the flowchart of FIG. 3 will be described.

First, at step 210, it is determined whether or not the combination of the displayed symbols is composed only of "3" and "7". When it is determined that such a combination is composed, the symbol is determined at step 220. It is determined whether or not the value of the number-of-times-of-change counter C3, which counts the number of changes since the power-on of the display device 25, is smaller than 51. When it is determined that the variation counter C3 is greater than 51, it is considered that a predetermined period has elapsed since the power was turned on at the time of opening the store, and the probability improvement subroutine is terminated. Go to 250. On the other hand, if it is determined in step 210 that the display symbol is not composed of only “3” and “7”,
At 30 it is determined whether it is a big hit or not. If it is not a big hit, the probability improvement subroutine ends. If it is a big hit, the big hit is any one of "3" or "7" or "9". Is determined. If not, the probability improvement subroutine ends. Also,
If it is determined in step 220 that the value of the variation counter C3 is smaller than 51, or if it is determined in step 240 that the big hit is any one of “3”, “7”, or “9”, At step 250, the high probability flag is set. As a result, the cycle in which the big hit symbol appears in the subsequent fluctuations is shortened. The change of the probability is set based on the flag described above in a probability change subroutine (not shown).

Also in the above-described embodiment, when the display symbol is composed of only a specific symbol combination between the time when the power is turned on at the time of opening the store and the time when the symbol display device 25 changes 50 times, Since the probability is improved, the atmosphere of the game hall at the time of opening the store can be enhanced. In addition, the number of times the symbol display device 25 has changed 50 times since the power was turned on.
When the number of times has exceeded the number of times, since the time has elapsed since the opening of the store, the condition for changing to the high probability is set to the normal state. In this embodiment, the shift from the high probability to the low probability may be shifted to the low probability based on the occurrence of the first big hit, or the occurrence of the second big hit or more times may be performed. The transition to the low probability may be made based on the occurrence of a big hit.

Although the configuration and operation of the pachinko machine 1 according to the embodiment have been described above, according to the embodiment, a pattern which appears relatively well within the predetermined period after the power is turned on at the time of opening the store, compared to the prior art, is provided. When the combination appears, the probability is changed to the high probability, so that the atmosphere of the game hall at the time of opening the store can be excited. In the above-described embodiment, the number of winnings in the starting winning opening and the number of times the symbol display device fluctuates are shown as the predetermined period from when the power is turned on, but, for example, the predetermined time (for example, 30 minutes) has elapsed. May be used as a condition. Further, the values of the start winning number, the number of fluctuations, the high probability, and the low probability in the above-described embodiment are examples,
It can be set arbitrarily. In addition, in order to distinguish between power-on at the time of opening a store and power-on at the time of recovery from a failure, a change to a high probability based on power-on is performed only when a predetermined switch operation or a permission signal from the management computer is derived. The processing may be executed. Furthermore, in the above-described embodiment, the opening and closing members 27a and 27b are opened based on the display result of the symbol display device 25. However, a predetermined game value is given to the symbol display device based on the display result. A pachinko machine having any game content may be used.

[0024]

As is apparent from the above description, according to the present invention, when a symbol combination that appears relatively more frequently than in the past appears within a predetermined period after the power is turned on at the time of opening a store, the probability is increased. Is changed to a high probability, so that the atmosphere of the game hall at the time of opening the store can be excited.
