SOLUTION: The picture pattern display device 13 provided on the game panel 1 of a pachinko machine is capable of variable-displaying the appearing probability of a bib winning pattern depending on a low probability mode and a high probability mode to stop varying after the lapse of a fixed time by a timer in the low probability mode after the starting of varying and to stop varying also by the pressurizing operation of the timer or a stopping switch 28 before the lapse of the fixed time by the timer in the high probability mode. Thus, it is impossible to intentionally make the big winning picture pattern appear at the right moment of the periodicity of the variation of a picture pattern in the low probability mode, it is possible to reduce the varying time in the high probability mode which does not frequently require the intentional appearance of the big winning pattern and the number of wasteful starting prize winning.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine such as a pachinko machine.

[0002]

2. Description of the Related Art Hitherto, a large number of pachinko machines have been introduced into the market in which a large hitting game state is developed based on the display of a big hit symbol as a result of a variable display of a symbol display device so that a large number of winning balls can be obtained in a short time. Had been provided. Most of such pachinko machines have the appearance probability of the big hit symbol as a fixed value, but in recent years there have been some proposals to change the appearance probability of the big hit symbol from a low probability to a high probability. I have. Then, such a pachinko machine automatically stops the fluctuation display when a certain time (for example, 6 seconds) elapses after the start of fluctuation, regardless of whether the appearance probability of the big hit symbol is low probability or high probability, Alternatively, the variable display time is reduced based on the fact that the player has operated the stop switch before the fixed time has elapsed.

[0003]

Since the symbol display is performed based on a certain probability, when the appearance of the big hit symbol has a certain degree of periodicity, the symbol display device stops the variable display. In the case where a stop switch is provided to reduce the fluctuation display time,
There has been a case where an operation to intentionally increase a possibility of the appearance of the big hit symbol is performed by giving an aim to the cycle in which the big hit symbol appears. In particular, there is a problem that such an operation is disadvantageous to the game arcade when the probability is low. For this reason, in recent years, pachinko machines that automatically stop variable display only with a timer without providing a stop switch are becoming mainstream. on the other hand,
The automatic stop by the timer alone has a disadvantage that the fluctuation time in the game time becomes relatively long, and also generally has a disadvantage that the start winning that allows the start of the fluctuation of the symbol display device is often invalidated. there were. In particular, when the variable display time is long at the high probability, the irritability of the player increases, and when the start winning is invalid at the high probability that there is no need to intentionally display the big hit symbol, the player is dissatisfied. There was a problem. Further, if the state of the jackpot does not easily reach the big hit state, the game balls are gradually consumed, and there is a possibility that the added value of the high probability cannot be fully enjoyed. The present invention has been made in view of the above-described problems, and has as its object to reduce the consumption of game balls as much as possible in a high probability state, thereby enabling the player to fully enjoy the added value of high probability. To provide machines.

[0004]

In order to achieve the above-mentioned object, in the present invention, it is necessary that a symbol display means capable of changing and displaying a symbol and that a fixed symbol of the symbol display means be a specific symbol. As a special game state generating means for generating a special game state advantageous to the player, and a probability switching means capable of switching the occurrence probability of the special game state to a plurality of stages, a relatively high probability state by the probability switching means When switched, the expected acquisition value of the prize ball given to the player is made higher than in the case of the relatively low probability state. Also, in this case, a prize device is provided in which a predetermined number of prize balls are paid out in accordance with a prize of the game ball, and in the case of the relatively high probability state, the prize probability to the prize device is changed to the relatively low probability state. It is preferable to increase the expected value of the prize ball given to the player by increasing the value higher than the case. Further, in this case, whether or not to generate the special game state is determined by a random number value obtained by a random factor from a random number counter provided inside the gaming machine, and the switching of the probability generates the special game state. It is preferable to configure so as to be performed by changing the probability of obtaining a random number value to be performed.

[0005]

[Action] The operation to increase the probability of occurrence of the special game state is originally
This is done to make it easier for the next special game state to occur and to give the player sufficient satisfaction, but even in this case, if the prize balls are not refunded, the state is high probability Nevertheless, a large amount of game balls are consumed, and there is a possibility that the satisfaction of the player due to the added value of the high probability state may be reduced. In this regard, according to the present invention, the prize ball can be expected to increase in the case of the high probability as compared with the case of the low probability, so that the above-mentioned satisfaction is prevented from decay and the added value of the high probability is sufficiently provided as originally intended. You can enjoy.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. First, a configuration of a game board 1 of a pachinko machine according to an embodiment will be described with reference to FIG. In the figure, a special winning device 4 is arranged substantially at the center of a game area 3 surrounded by a guide rail 2 of a game board 1. The special prize winning device 4 has a plurality of passing areas 5, 6 a, 6 b including a special device operating area 5, turns a hit ball received from above using a spiral disk, and passes any one of the passing balls during the turning. It is to be dropped on the areas 5, 6a, 6b. The left and right passing areas 6a and 6b are configured as a winning passing area in which a predetermined number (for example, 15) of prize balls are discharged by dropping a hit ball. The special device operating area 5 in the center is guided downward as it is when the hit ball falls, and the special winning opening 7 arranged below the special winning device 5 is made to win. When a ball is hit in the special winning opening 7, a predetermined number of prize balls are discharged in the same manner as described above, and the special winning ball detecting switch 24 (see FIG. 2) built in the special winning opening 7 is turned on.
Let it. The ON signal of the special winning ball detection switch 24 is used as a signal for detecting occurrence and disappearance of the right generation state. In the illustrated embodiment, only a hit ball guided by an electric winning device 16 described later is guided to the special winning device 4.

Below the special winning device 4, a variable winning device 8 is arranged. This variable winning device 8
It has an attacker opening / closing plate 9 driven to be opened and closed by an attacker solenoid 9a (see FIG. 2), and receives a hit ball falling in the game area 3 with the attacker opening / closing plate 9 opened. However, the opening of the attacker opening / closing plate 9 is executed based on the fact that the right generation state is continued and a hit ball is won in the starting winning opening 11 described later, and one opening is performed by a predetermined number (for example, Until ten winning balls are generated, or for a certain period of time (for example, 9.7)
Seconds) has elapsed. In order to count the above-mentioned predetermined number, the variable winning device 8 is provided with a winning ball number detecting switch 26 (see FIG. 2), and detects the number of winning balls detected by the winning ball number detecting switch 26. A winning number indicator 10 is built in for displaying.

[0008] Below the variable winning device 8, there is a starting winning opening 1
1 is provided. The start winning opening 11 is for opening the attacker opening / closing plate 9 based on the fact that the right generation state is continued as described above and a hit ball is won. Board 9
Therefore, when the attacker opening / closing plate 9 is open, it is difficult for a hit ball to win the starting winning opening 11. The start winning opening 11 is provided with a start winning ball detection switch 25 (see FIG. 2) for detecting a winning of a hit ball. Furthermore, during the right generation state, the starting winning opening 1
The number of balls that have won 1 is displayed on a start winning number display 17 provided on one side (the right side in the figure) of the special winning device 4. The start winning number display 17 indicates the number equal to the number of times the attacker opening / closing plate 9 is opened in many cases. When the numerical value displayed on the start winning number display 17 becomes 16, the right generation state ends. Note that the number of prize balls discharged by hitting the starting winning opening 11 with a hit ball is set to a smaller number (for example, seven) than the number of prize balls discharged by other winning holes.

[0009] Gate winning ports 12a and 12b are arranged substantially at the center and left and right of the game area 3, respectively. The gate winning ports 12a, 12b are not configured to discharge prize balls merely because a hit ball falling in the game area 3 passes therethrough, but the gate winning ports 12a, 12b.
This is expressed as a winning opening in the sense that the variable display of the symbol display device 13 provided on one side (the left side in the drawing) of the special winning device 4 is controlled by the passing of the hit ball through b. Of course, in this case, a winning opening from which a prize ball is discharged may be used. The gate winning ports 12a and 12b are provided with a gate winning ball detection switch 23 (see FIG. 2), and the symbol display device 13 performs variable display based on the detection signal.

The symbol display device 13 includes a plurality of (two in the illustrated embodiment) symbol indicators 14a and 14b (consisting of 7-segment LEDs) and a gate prize storage indicator 15.
It is comprised including. Symbol display 14a, 14b
Is the gate winning opening 12 at a low probability described later.
The variable display is started based on the fact that the hit ball has won a and 12b, and after a predetermined time (for example, 6 seconds) elapses, the left symbol display 14a stops, and then the right symbol display is delayed with a slight delay. 14b is controlled to stop. Also, after the start of fluctuation at the high probability described below,
Even before the predetermined time elapses, when the player operates the stop switch 28 provided on the front surface of the pachinko machine, the pachinko machine sequentially stops as described above.

The symbols displayed on the left symbol display 14a are, for example, ten types of numeric symbols from 0 to 9 being variably displayed, and the symbols displayed on the right symbol display 14b are, for example, 0-9, A, C, E, F, H, J, L,
Nineteen numbers and alphabetic symbols from P to U are displayed in a variable manner. And both symbol display 14
When the combination of symbols at the time of stop of a and 14b is a combination of "3, 3" or "7, 7", it is determined that a hit has occurred, and an electric winning device 16 described later is opened and driven. . In addition, the symbol indicators 14a and 14b use two-color light emitting segment LEDs. For example, when the variable display is performed with low probability, for example, the display is displayed in red, and when the variable display is performed with high probability, for example, The display is controlled so that the display is fluctuated in green. In this way, the player can immediately know at what probability the symbol display device 13 is variably displaying.

Further, the gate winning storage display 15 provided in the symbol display device 13 is provided with the gate winning opening 12a, 1
This informs that up to four hit balls that have passed through 2b have been stored. Even if the hit balls pass through the gate winning openings 12a and 12b with all four of the gate winning storage indicators 15 lit, it does not matter. Treated as invalid.

By the way, the symbol indicators 14a, 14b
When the combination at the time of stop becomes a winning symbol combination, the electric winning device 16 arranged above the special winning device 4 is opened for a predetermined time (for example, 6 seconds). The illustrated electric winning device 16 is a so-called tulip-type winning device, and is opened and driven by a tulip solenoid 16a (see FIG. 2). Thus, when the tulip solenoid 16a is excited and the electric winning device 16 is opened, the hit ball falling in the game area 3 is easily accepted, and the hit ball received by the electric winning device 16 is guided to the special winning device 4. , Falls into one of the plurality of passing areas 5, 6a, 6b. It should be noted that when one hit ball is won in the electric winning device 16, the tulip solenoid 16a is turned off and closed even before a certain time has elapsed. Further, in the illustrated electric winning device 16, an obstacle nail is provided so that a hit ball does not win at all when the electric winning device 16 is closed, but the electric winning device 16 is closed. At any time, a hit ball may be won.

Further, in addition to the above-described configuration, a plurality of winning ports 18, 19a, 19b, 2
0a, 20b, operation lamps 21a, 21b, and out port 2
2 are provided. Of these, the operation lamps 21a, 21
b mainly informs that the right is in the right generation state, and a lamp group (not shown) that informs that the illustrated display device 13 and the variable prize winning device 8 are being driven is provided by each of the prize devices and the prize. Mouth 19a, 19b, 20a, 20b
And so on.

The configuration of a control device for controlling the operation of the symbol display device 13, the special prize device 4, the variable prize device 8 and the like as the symbol display means described above will be described with reference to FIG. FIG. 2 is a block diagram showing an electrical configuration of the control device. The control device uses a microcomputer 30 as a special game state generating means and a probability switching means. An external ROM 31 and an external RAM 34 are connected to the microcomputer 30. The ROM 31 has an outlier numerical value table 32 for determining numerical values to be displayed on the symbol displays 14a and 14b in the off mode shown in FIG. 8, and a symbol display 14a and 14b in the hit mode shown in FIG. A hit numerical value table 33 for determining a numerical value to be displayed is set.

Has a memory for the number of reserved winning balls of the gate winning ports 12a and 12b + 1. The numerical value for mode determination for each retained winning prize ball is determined at the time of winning (passing), and the numerical value is stored in each determination memory 38. As described later, the maximum value of the mode determination counter 35 is changed to change the occurrence probability of the hit mode.

On the other hand, a gate winning ball detection switch 23 for detecting a passing ball in the gate winning opening 12a, 12b, a special winning ball detecting switch 24 for detecting a winning ball passing through the special device operating area 5, a winning in the starting winning opening 11. Start winning prize ball detecting switch 25 for detecting a ball, winning prize ball detecting switch 2 for detecting a winning ball on the attacker opening / closing plate 9
6. The tulip detection switch 27 for detecting a winning ball in the electric winning device 16 and the stop switch 28 for stopping the fluctuation at a high probability are controlled via a waveform shaping circuit 39 comprising a flip-flop for preventing chattering. It is connected to a computer 30.

The clock generation circuit 41 outputs an external interrupt signal via the frequency divider 40 to the IN of the microcomputer 30.
Output to T terminal. Then, the microcomputer 30 executes the main program shown in FIGS. 3 to 5 in synchronization with the external interrupt signal. A timing signal output from the timing signal generation circuit 42 is input to an RST1 terminal of the microcomputer 30, and a numerical value generation program shown in FIG. 7 is started in synchronization with the timing signal. The reset signal output from the reset signal generation circuit 43 by the ON operation of the power supply circuit 44 is input to the RST2 terminal of the microcomputer 30, and the reset signal starts the initial program shown in FIG.

A display drive circuit 45, a display selection circuit 46, and a driver 47 are connected to each output port of the microcomputer 30. The display drive circuit 45 and the display selection circuit 46 include the symbol displays 14a and 14 described above.
b, gate winning memory display 15, winning number display 10,
The start winning number display 17 is connected. These displays are dynamically driven by outputting selected data and display data from the microcomputer 30 at regular intervals. That is, each display unit is selected by the display selection circuit 46 and displayed according to the output signal of the display drive circuit 45 at that time. The driver 47 includes a tulip solenoid 16a, an attacker solenoid 9a, and an operation lamp 2 according to a signal from the microcomputer 30.
1a, 21b and a lamp group (not shown) are driven and controlled.

Next, the operation controlled by the above-described control device will be described with reference to a flowchart showing a processing procedure of the microcomputer 30. (1) Initial setting at power-on When the power supply circuit 44 is turned on, power is supplied to the microcomputer 30 and the reset signal generation circuit 43
Outputs a reset signal to the RST2 terminal. Then
Microcomputer 30 (hereinafter referred to as CPU 30)
Executes the processing shown in FIG. That is, the symbol display 14
The two-digit numerical registers X1 and X2 displayed on a and 14b are set to the initial values (1, 5). In addition, gate winning opening 12
The gate winning counter C for counting the number of reserved balls awarded to the a and 12b is set to “0”, and the starting winning ball counter D for counting the number of winning balls to the starting winning opening 11.
To “0”, a winning ball counter E for counting the number of balls winning the attacker opening / closing plate 9 to “0”, a tulip winning counter B for detecting a ball winning to the electric winning device 16 to “0”, An opening number counter G for counting the number of times the attacker opening / closing plate 9 is opened is initialized to "0", and an operation number counter L for counting the number of operating times of the special device is initialized to "0". Also, status registers F, which store the control status,
H is set to "0" and timers T1, T2, T3 and T4 are set to "0".
Initialize to. Then, the numerical value I of the mode determination counter 35 is set to the initial value “1”, and the outlier numerical value table 3
The address J of No. 2 and the address K of the hit numerical value table 33 are each set to the initial value “1”. Although not shown, the probability increase flag and the right generation flag are reset at the time of the initial setting, and the green flag is also reset.

(2) Step of the mode determination counter and rotation of the numerical value table The numerical value generating program shown in FIG. 7 is started in synchronization with the timing signal input from the RST1 terminal. That is, it is determined in step 300 whether or not the probability increase flag is set. If not, Imax = 190 is set in step 302 as the final value of the numerical value incremented by the mode determination counter 35. , If set, the final value of the numerical value incremented by the mode determination counter 35 is set to
x = 19 is set. Then, in the next step 306, it is determined whether or not the value is equal to or more than the set final value.
The value I of 5 is incremented by one. Step 306
When it is determined that the numerical value I of the mode determination counter 35 is equal to or more than the final value, the routine proceeds to step 310, where the numerical value I of the mode determination counter 35 is set to 1 as the initial value. In this way, the mode determination counter 35 generates a mode determination numerical value that is sequentially incremented in the range from the initial value 1 to the final value at an arbitrary time after the power is turned on. The generation speed of the numerical value at this time is determined by the timing signal output from the timing signal generation circuit 42.

Similarly, in step 312, the numerical value stored at the address J is read from the numerical value table 32 for display in the deviating mode, and the numerical value is stored in each of the two digits of the deviating numerical value memory 37. It is memorized. Then, in the next step 314, it is determined whether or not the value of the address J is out of range and the final value of the address in the numerical value table 32. If not, the address J is incremented by 1 in step 316. If it is determined in step 314 that the value of the address J is the final value, the process proceeds to step 318, where the value of the address J is set to 1 as the initial value. Similarly, in steps 320 to 326, the numerical value stored in the address K of the hit numerical table 33 for display in the hit mode is stored in the hit numerical memory 37 as the hit mode display numerical value, and the address K is updated. When the value exceeds the final address of the hit numerical value table 33, the process of setting the initial value 1 is performed. In this way, every time a timing signal is input, the numerical value for display in the out-of-off mode is stored in the out-of-value memory 36, and
The display numerical value in the hit mode is stored. Each memory may store the address of the table so that the numerical value of the table at that address is read at the time of display.

(3) Main Program After the initial setting, each time an external interrupt signal output from the frequency divider 40 is input, the CPU 30 executes the main program shown in FIGS. In FIG. 3, at step 100, a timer updating process is performed, and at step 102, the state signals S1, S2, S3, S4, S5 of the switch group are read. These status signals are configured by negative logic, and when the signal is at a low level, the switch is in the ON state, indicating that a winning ball has been detected.

When the falling of the gate winning signal S1 is detected in step 104, step 106
It is determined whether or not the number of pending winning balls is smaller than four. Only when the number is smaller, the gate winning counter C is determined in step 108.
Is updated by 1 and the value of the mode determination counter 35 at that time is stored in the determination memory M (c) 38 at step 110. That is, when there is no pending winning ball, the gate winning opening 12
When a prize is detected in a or 12b, the gate prize counter C becomes 1, and the value of the mode determination counter 35 at that time is stored in the determination memory M (1). When the gate winning counter C is 1 or more, the gate winning port 12 is further increased.
When the player wins a or 12b, the winning ball becomes a reserved winning ball, and the gate winning counter C is incremented by one. Then, the value of the mode determination counter 35 at the time of winning is stored in the determination memory M (c) corresponding to the held winning ball. In this way, when the winning in the gate winning openings 12a and 12b is achieved, the numerical value for determining the winning mode is determined.

In step 112, a special winning signal S2
Is detected, it is determined in step 114 whether or not the right generation flag has been set. If not, the right generation flag is set in step 116. As a result, a right is generated. Then, when the right is generated, step 11 is executed.
If it is determined in step 8 that the probability increase flag is set, the probability increase flag is reset in step 120, and the green flag is reset in order to indicate that the symbol displays 14a and 14b are to be displayed with a low probability. This allows
The symbol display displayed on the symbol indicators 14a and 14b is displayed in red, thereby informing the player that the probability that the symbol is displayed is low. Then, thereafter, in step 122, the operation number counter L is incremented by one. On the other hand, when it is determined in step 114 that the right occurrence flag has already been set, the special winning signal S2 is treated as a signal for extinguishing the right occurrence state, and the process proceeds to step 132 described later.

In step 124, the start winning signal S3
Is detected, it is determined in step 126 whether or not the right generation flag is set. If the right generation flag is not set, the following steps 128 to 136 are not performed. On the other hand, when the right occurrence flag is set, the start winning ball counter D is incremented by 1 in step 128, and thereafter, in step 1
At 30, it is determined whether the value of the starting winning ball counter D is greater than 15. If the value is greater than 15, the right generation flag is reset in step 132 to end the right generation state, and it is determined in step 134 whether the value of the operation counter L at that time is an odd number. When the value of the number-of-operations counter L is an odd number, step 136
At the same time, a green flag is set to indicate that the symbol displays 14a and 14b are to be changed with a high probability. As a result, the symbol displayed on the symbol indicators 14a and 14b is displayed in green, thereby notifying the player that the probability that the symbol is displayed is high.

Steps 112 to 122 described above
And Steps 132 to 136 are executed when the right generation state ends based on the passage of a hit ball to the special device operation area 5 and the predetermined number of hit balls to the starting winning opening 11 during the right generation state, and the end is an odd number. This indicates that the probability of the winning mode of the symbol display device 13 at the end of the round increases, and that the probability increase state is resolved at the start of the next right generation state. Since there is a tendency that the gaming state in which the right is generated and the gaming state in which the right is not continuously generated tend to occur alternately, the game can be inflected and the interest of the player can be attracted. Further, since the change in the probability of the hit mode can be distinguished by the color of the variable display of the symbol indicators 14a and 14b, the player can immediately know at what probability the symbol display device 13 has the variable indicator. Can be.

Further, in step 138, the winning ball number signal S4
Is detected, at step 140, the winning ball counter E is incremented by one. Step 1
When the falling of the tulip winning signal S5 is detected at 42, the value of the tulip winning counter B is set to 1 at step 144.

Steps 146 to 146 shown in FIGS.
The processing of 180, 212 to 218 is performed by the symbol display device 1
Steps 182 to 218 are processing steps corresponding to the states of the variable prize apparatus 8 during the right generation state. Then, the symbol display device 13 and the electric winning device 16
Is performed regardless of whether or not the right is being generated.

First, processing steps corresponding to the states of the symbol display device 13 and the electric winning device 16 will be described. (A) Processing when there is no gate winning ball When there is no gate winning ball, that is, when the gate winning counter C is 0, steps 100 to 150 and 18 are executed.
Steps 2 to 218 are performed. At this time, step 21
The processing of the symbol display devices 14a, 14b, lamp groups, and the solenoids 9a, 16a of 2 to 218 performs predetermined display or driving according to the state of flags, registers, and the like.

(B) Variation display processing In step 150, the value of the counter C is determined. When a winning is detected, the value of the counter C is decremented by one, and a register F is set to 1 to indicate the variation display state. The timer T1 is set to a predetermined value (for example, 6 seconds) (steps 152, 1
54). Then, as the gate winning counter C is decremented in step 156, the contents of the determination memory M (c) 38 are incremented by one and updated. Then step 15
In step S8, it is determined whether or not the timer T1 has timed out. If it is determined that the time has not expired, it is determined in step S160 whether or not the probability increase flag has been set. If the probability increase flag has been set, it is determined in step 162 whether or not the stop switch 28 has been depressed. The value of 35 is stored in the determination memory M (0), and the numerical value temporarily determined in the determination memory M (0) is rewritten by the finally determined numerical value. Further, when the probability increase flag is not set, the fluctuation stop control is performed only by the time-up of step 158. In this case, however, step 1 is performed by the time-up of the timer T1.
The routine proceeds to 66, where the temporary numerical value stored in the determination memory M (0) is determined as the final mode determination value.

If it is determined that the stop switch 28 has been depressed when the predetermined time has elapsed or at a high probability, the hit mode is determined in step 166 from the numerical value stored in the determination memory M (0). For example, when the value of the mode determination counter is “3”, it is determined that a hit has occurred, and when the value is any other value, it is determined that the hit has occurred. And
If it is determined in step 168 that it is not a hit, the flow proceeds to step 170 in which the values of the respective digits of the out-of-office memory 36 storing the display values in the out-of-off mode are set in the number display registers X1 and X2. As a result, on the symbol displays 14a and 14b, the display numerical values in the off mode stored in the off value memory 36 are displayed.
On the other hand, if it is determined that a hit has occurred, then step 17
The value of each digit of the hit value memory 37 storing the display value in the hit mode in the hit mode is stored in the numerical display registers X1, X
2, the symbol displays 14a, 14b
The display numerical value in the hit mode stored in the hit numerical value memory 37 is displayed in.

In this way, the symbol indicators 14a, 14
In b, a numerical value for display generated by a numerical value table for exclusive use and a numerical value table for hitting, which is different from the numerical value generating means for determining the mode, is displayed. Also,
Since the maximum value of the mode determination counter 35 is changed as shown in FIG. 6, the probability that the numerical value stored in the determination memory M (c) is a hit value is determined when the probability increase flag is set. It is 1/19, and when the probability increase flag is not set, it is 1/190. Until the timer T1 expires, steps 100 to 1 are executed.
46, 158, 160, 182 to 218 are repeated, and the steps 100 to 146, 158, 160, 162, 182 to 182 are executed until the timer T1 times out or the stop switch 28 is depressed at a high probability.
Step 218 is repeated.

(C) Processing at the time of hit When the result of the determination at step 168 is a hit, the tulip solenoid flag is set at step 174 to indicate that the tulip is being opened.
And a predetermined time (for example, 6 seconds) is set in the timer T2. The tulip solenoid 16a is energized until it is determined in step 176 that the timer T2 has expired or in step 178 that the value of the tulip winning counter has become 1, so that the hit ball is electrically driven. The winning device 16 is kept in a state where it is easy to win. When the predetermined time has elapsed or when the value of the tulip winning counter B is set to 1, the tulip solenoid flag is reset in step 180, and the status register F and the tulip winning counter B are set to zero. As described above, when it is determined that a hit has occurred, the electric winning device 16 accepts one hit ball or opens the ball until a certain time elapses. Therefore, the possibility that the hit ball is guided to the special winning device 4 is increased. The likelihood that the hit ball passes through the special device operation area 5 to generate a right is also increased. In addition, after the open state of the electric winning device 16 ends, after a predetermined interval, the variable display of the next symbol display device 13 may be started. Here, when the probability is high, the chance of hitting the electric prize winning device 16 with the electric prize device 16 is increased, so that the expected value of the prize ball given to the player before the right is generated is higher than that at the time of the low probability. .

Next, the processing steps of the variable winning device 8 will be described. (D) Processing in the Right Generation State When it is determined in step 186 and step 188 that the value of the starting winning ball counter D is 1 or more and smaller than 17 and larger than the value of the opening counter G, the attacker solenoid is determined in step 190. The flag is set, and the status register H indicating that the attacker opening / closing plate 9 is being opened is set to 1. Thereafter, the opening counter G is increased by 1 in step 192. Then, in step 194, a timer T3 for regulating the opening time of the attacker opening / closing plate 9 is set to a predetermined value (for example, 9.7 seconds).
Until it is determined that the time is up in step 6, or step 198
, The attacker solenoid 9a is excited until the winning ball counter E reaches 10. Thereafter, when a predetermined time has elapsed or when the winning ball counter E reaches 10, in step 200, the attacker solenoid flag is reset to release the excitation state of the attacker solenoid 9a, and the winning ball counter E is reset. Set to 0.

When one open / close state of the attacker opening / closing plate 9 is completed, an interval time is provided until the next opening / closing.
Steps 202 and 204 are performed. Then
If the interval time has elapsed, step 206
The register H is set to 0 at step 208, and at step 208, it is determined whether or not the right generation flag is set. If the right occurrence flag is set, the process immediately proceeds to step 212. If not, the value of the starting winning ball counter D and the number of open counters G is set to 0 in step 210 and the process proceeds to step 212. I do.

In steps 212 to 218, the symbol indicators 14a and 14b, the lamp group including the operation lamps 21a and 21b, the tulip solenoid 16a, and the attacker solenoid 9a are driven according to the state of the flag or the register. During the variable display of the symbol indicators 14a and 14b, the contents of the out-of-place numerical value table 32 are displayed in a variable manner at a speed that cannot be identified in order.

The embodiment has been described above.
In the above embodiment, the segment LEDs are illustrated as the symbol indicators 14a and 14b, but other indicators may be used, and the numerical values of the high probability and the low probability may be set arbitrarily. In addition, the number of times of changing to the high probability may be not only at the end of the odd number, but also at the end of an arbitrary number or a random number, or a right generation state with a high probability may be repeated plural times. . Furthermore, although the pachinko machine in which the right-winning game state is set to the right generation state is shown, the so-called digital pachinko machine in which the variable winning device is driven in a predetermined manner when the combination of the symbol display devices becomes a combination of the big hit symbols. Machine.

[0039]

As is apparent from the above description, the operation for increasing the probability of occurrence of the special game state is intended to make it easier to generate the next special game state and to give the player sufficient satisfaction. This is done for a reason, but in this case, if the prize ball is not refunded, a large amount of game balls will be consumed despite the high probability state. There is a possibility that the satisfaction of the person is attenuated. In this regard,
According to the present invention, the prize balls can be expected to increase in the high-probability state compared to the low-probability state, so that the above-mentioned satisfaction is prevented from decay and the added value of the high probability is fully enjoyed as originally intended. be able to.
