Abstract

PURPOSE:To equalize the chance for obtaining profits given to a player by providing a variable prize-winning device formed so that it can be converted to a first state being disadvantageous to the player and a second state being advantageous to the player with regard to prize-winning of a game ball discharged onto the game board surface. CONSTITUTION:When a game ball detector 21 detects a game ball passing through a passing chucker 6L or 6R, it is driven so that numerals of 0-9 are displayed variably on a variable indicator 7, and on the other hand, a random number is generated at every prescribed time and its value is decided, and after a prescribed time, the variable display is stopped by displaying the numeral corresponding to the value of the random number. As a result of random number decision, in the case the final display corresponds to a specific numeral, variable prize-winning devices 3L, 3C and 3R being start ports are driven to convert to a second state being advantageous to a player, and when a prescribed time elapses, the conversion driving is stopped and each variable prize-winning device 3L, 3C and 3R is reset to a first state. The variable prize-winning devices 3L, 3C and 3R become a first state by closing a pair of movable pieces installed on the game board surface, and becomes a second state by opening the movable pieces. In such a way, a chance for prize-winning to the variable prize-winning device and obtaining profits which follow it can be given equally to the player.

Description

[Detailed Description of the Invention] "Industrial Application Field J The present invention relates to pinball game machines such as pachinko machines,
Specifically, a pinball game machine is provided with a variable winning device configured to be convertible between a first state disadvantageous to the player and a second state advantageous to the player regarding the winning of game balls fired onto the game board surface. Regarding.

[Prior Art] In conventional pachinko gaming machines, profits (prize balls) are given according to the number of game balls that enter the variable winning device as described above. 2. Description of the Related Art A pachinko game machine is known that provides players with an opportunity to play a game other than a pachinko game and earn a large profit depending on the result. In this type of pachinko game machine, a display device that variably displays numbers and pictures is installed on the game board surface as a representative game, and a game ball launched onto the game board surface enters a winning hole called a starting hole. A variable winning device called a tulip or an attacker is converted into a state advantageous to the player depending on the result when the variable display is stopped by the player's stop operation or after a certain period of time has elapsed. That's what I do. Furthermore, in order to give many players the opportunity to earn profits through different games, it is also considered that the results of different games appear based on preset probabilities.8 [Problems to be Solved by the Invention] However, As mentioned above, even if the outcome of another game that brings a large profit to the player appears with a certain probability, the other game will not start unless the game ball enters the starting hole,
Similar to the conventional variable winning device in which winning in the starting slot is not guaranteed, winning in the starting slot also highly depends on the skill of the player.

In addition, in conventional pachinko machines, adjusting the nails near the winning device or placing the winning device in a position where it is difficult for game balls to win, especially for a specific player, who is said to be a professional, can affect the skill of the player. Poor players are at a particular disadvantage, unable to play the other games mentioned above, and as a result, there is a large difference in the number of prize balls won depending on the skill of the player. The problem was that there was a lack of equality.

Therefore, a pinball game machine was developed in which the number of game balls that enter the variable winning device is adjusted according to the probability based on the detection of the fired balls, thereby equalizing the opportunity for players to earn profits. A patent application has been filed by a person (Patent Application Hei 1)
-109685).

In this pinball game machine, when a first random number generated in response to a detection signal from a game ball detection means arranged on the game board surface is determined to be a predetermined value, the variable winning device is activated to provide a disadvantageous system to the player. a first state that is driven to convert from one state to an advantageous second state, and converts the variable winning device to the second state based on a determination result regarding a second random number generated in response to a detection signal from the shot ball detection means; It is designed to change the probability of random numbers appearing, and by adjusting the probability of state conversion of the variable winning device, it is possible to give equal opportunities to win in the variable winning device and earn profits associated with it. .

By the way, in current pachinko machines, when the firing handle is operated, a predetermined number of balls are fired in a predetermined time (for example, 100 in 60 seconds).
A firing device that fires several pachinko balls has been adopted for shooting purposes. In this case, sampling of random numbers for prize winning control as described above can be performed without actually detecting a shot ball. In other words, if a random number is sampled each time a shot ball is detected as described above, and the random number is set to a predetermined value with a probability of, for example, 1/100, the predetermined value for 100 shot balls is set. This means that a random number of a predetermined value is generated once in 60 seconds in a pachinko machine equipped with the above-described firing device.

From this point of view, the present invention provides players with the opportunity to earn profits by adjusting the number of game balls that enter the variable winning device according to the probability based on random number sampling, without actually detecting the fired balls. To provide a pinball game machine that equalizes the following.

[Means for Solving the Problems] The present invention provides a firing device that is driven to fire a predetermined number of game balls onto a game board surface within a preset time in response to a player's firing operation; In a pinball game machine having a variable prize winning device configured to be convertible between a first state disadvantageous to the player and a second state advantageous to the player regarding winning of game balls fired from the firing device, firing operation detection means for detecting a firing operation by a person;

Alternatively, a winning hole into which a game ball can be received may be provided at a predetermined position on the game board surface, and a sensor may be used to detect the game ball that has entered the hole.

A variable display is provided on the game board surface to variably display numbers, etc. in accordance with the detection signal from the game ball detection means, and when the control means determines that the value of the first random number is a predetermined value, the variable display is It is preferable to drive and control the variable indicator so that it stops in a specific result manner.

The control means changes the probability of appearance of the first random number that converts the variable prize winning device into the second state when the number of times the second random number generated by the random number generation means is determined to be a predetermined value exceeds a certain number. It is preferable to configure it as follows.

Another aspect of the present invention provides a firing device that is driven to fire a predetermined number of game balls onto a game board surface within a preset time in response to a firing operation by a player, and The first thing that is disadvantageous to the player regarding the winning of game balls that are
A pinball game machine that is configured to be convertible between a state and a second state that is advantageous to a player, and has a starting port that starts a different game when a game ball wins, and a separate game device for playing a different game. A firing operation detection means for detecting a firing operation by a player;
A first random number is generated according to a detection signal from the game ball detection means arranged on the game board surface and the game ball detection means, and the value of the first random number is determined, and the value of the first random number is determined. when the starting port is driven to convert into a second state, a second random number is generated at predetermined time intervals according to a detection signal from the firing operation detection means, and the value of the second random number is determined; Changing the probability of appearance of the first random number that converts the starting port to the second state according to the result, further generating a third random number at predetermined time intervals, determining the value of the third random number, and determining the value of the third random number. is a predetermined value, the game apparatus is characterized by comprising a control means for controlling the separate game device so that the separate game that is started by winning the starting hole ends with a predetermined outcome.

Here, the control means includes a first random number generation section that generates random numbers in response to a detection signal from the game ball detection means, and outputs a timing signal at predetermined time intervals in response to a detection signal from the firing operation detection means. a timekeeping section, a second random number generation section that generates a random number in response to a timekeeping signal from the timekeeping section, and a third random number generation section that generates a random number separately from the second random number in response to a timekeeping signal from the timekeeping section.

In addition, as a separate game, for example, a variable display device that variably displays a plurality of numbers, letters, or figures on the game board surface is provided, and when a game ball enters the starting hole, the numbers, etc. are displayed by a signal from the control means. A variable display is performed, and the variable display is stopped in a result manner corresponding to the value of the third random number. Furthermore,
When a different game ends with a specific result, the player can use the variable or variable prize winning device placed on the game board! It may be converted to a 1 state.

[Function] In the pinball game machine of the present invention, the player can shoot and operate (
For example, when the user operates the handle, a predetermined number of game balls are fired from the firing device within a set time.

At this time, when the game ball detection means detects the game ball shot onto the game board surface, the control means generates a first random number according to the detection signal, and when the value of the random number is determined to be a predetermined value, the control means generates a first random number. , converts and drives the variable prize winning device to the second state. This conversion drive includes not only the case of continuing the second state but also the case of repeating the first state and the second state alternately.The conversion drive of the variable prize winning device is performed, for example, when a predetermined time has elapsed or When the number of game balls is won, the variable winning device is returned to the first state and the process ends.

On the other hand, when the player performs a firing operation, the firing operation detection means (for example, a switch that turns on in conjunction with the handle operation)
outputs a detection signal. In response to the detection signal, the control means generates a second random number at predetermined time intervals, and changes the probability of appearance of the first random number that converts the variable prize winning device to the second state based on the determination result. Thereby, the number of game balls that enter the variable winning device can be adjusted.

Further, in a pinball game machine equipped with a variable display device as a starting port for starting a game other than the normal pinball game when a game ball fired onto the game board wins a prize, the control means may A third random number is generated every time, and when the random number is determined to be a predetermined value, a separate game device is controlled so that a separate game started by winning a prize in a starting hole is ended in a predetermined result manner. That is, when a game ball enters the starting hole during the conversion drive as described above, another game is started, but the result mode is determined by the value of the random number, and the different game ends in the result mode.

As mentioned above, in the case of a pinball game machine that allows separate games, the result of the separate game that is started by converting the starting port to the second state and winning the starting port is determined by a random number generated every predetermined time. By determining the probability of each taking a predetermined value, players are given equal opportunities to win in the starting slot and to earn profits according to the results of other games. You can manage winning rates without making adjustments.

The probability that a random number takes a predetermined value is, for example, if the time for a predetermined number of game balls to be fired from a firing device by a player's firing operation is set to 60 seconds, and a random number of a predetermined value will be fired once within that set time. If the random number is sampled every second, the probability is 1/60, if it is sampled every 5 seconds, the probability is 1/12, and if it is sampled every 60 seconds, the probability is 1/12. The probability is l/l. By generating random numbers that take a predetermined value at predetermined intervals in this manner, the same control can be achieved even without detecting a shot ball.

[Example] FIG. 1 is a front view of a pachinko game machine that is an example of the present invention.

This pachinko game ML allows a different game to be played when a game ball fired onto the game board surface 2 enters the starting hole. A plurality of variable winning devices 3L, 3C, and 3R, which are converted into a second state in which the game is possible, are each arranged as a starting port. Further, in the center of the game board surface 2, a variable display device 4 is arranged as a separate game device, and below it, a variable prize winning device 5 is provided which has a door that opens when the result of a separate game becomes a specific display mode. It is being

The variable display device 4 has a 7-segment LED (light emitting diode) display that variably displays a plurality of numbers (for example, 3) within a rectangular window. A display drive circuit 34 controlled by an output signal from a control signal generating section 30 shown in FIG. Note that the display device may display not only numbers but also characters, figures, and the like.

The variable winning device 5 is called an attacker, and has a door of approximately the same shape attached to the front side of an opening provided in the upper part of a trapezoidal front plate so as to be openable and closable, and has a winning opening in the opening. The door of this variable prize winning device 5 is opened and closed by a drive mechanism whose power source is a solenoid attached to the back side of the front plate.

On the left and right sides of the variable display M4, there are passing chuck cars 6L as a type of winning opening into which game balls fired onto the game board surface 2 enter.
, 6R are arranged. Each chutker has a hole on the game board surface 2 through which a game ball can pass, and is formed by covering the front side of a passing ball detector that detects a game ball that has passed through the hole with an appropriate cover. The ball detector is provided as a game ball detector 21 (Fig. 4) for detecting when a game ball shot onto the game board surface 2 passes through a specific area, but it is used instead of a passing chucker. It is also possible to provide a winning hole into which balls are placed, and to detect game balls (winning balls) that have entered the hole with an appropriate detector.

Above the display section of the variable display device 4, a variable display 7 is arranged that variably displays numbers from 0 to 9 in accordance with a detection signal from a game ball detector 21, which will be described later. This display 7 is
For example, it is composed of a known 7-segment LED.

Incidentally, a large number of nails are arranged on the game board surface 2 as a guide means for guiding a single fired game ball to the upper part of the variable prize winning device, etc., and a firing handle 20 is provided at the lower right side of the front, When a person operates this, a game ball is fired from a later-described firing device attached to the back side of the game board and moves along a guide rail 8 on the game board surface 2.

Further, as firing operation detection means, a handle operation detection switch 40 (FIG. 4) is provided which is turned on in conjunction with the operation of the firing handle 20.

As the game ball firing device, for example, one shown in FIG. 2 is used. This firing device 9 uses a plunger 10 by electromagnetic force.
It consists of a ball launching part II including a solenoid that projects the game ball P and makes the game ball P fly out, and a ball hitting guide part I2 provided on the plunger protruding side. The ball-hitting guide part I2 is formed of a cylindrical member with a cut-out tip for feeding the game ball P, and has a pair of holes on its internal bottom surface that guide the game ball P bounced by the tip of the plunger 10 forward. parallel protrusions 1
It has 3. The game ball P sent into the batting ball guide 12 stops at a position (launching position) where it abuts the tip of the plunger 10 on the protruding ridge 13, and when firing, the plunger IO protrudes due to the urging of the solenoid. It is bounced off and fired forward.

In order to detect each time a game ball P is fired from the above-mentioned firing device 9, a firing ball sensor 1 is provided in front of the firing device 9.
4 is placed. This shot ball sensor 14 is composed of a magnetic sensor having a hole through which the shot game ball P can pass.
The output is sent to a clock section 42 (FIG. 4), which will be described later.

The firing ball sensor 14 is not limited to being placed in front of the firing device 9 as described above, but may be placed at the game ball firing position. In that case, when a signal for operating the firing device 9 is detected while the firing ball sensor 14 is detecting a game ball, a firing ball detection signal is output. According to this method, since detection is made only after the firing device 9 operates while the game ball is in the firing position, it is possible to reliably detect that the game ball has been correctly fired.

As shown in FIG. 3, the game ball P fired from the firing device 9 passes through the firing ball path I5 and rises along the guide rail 8 toward the game board surface 2, but does not reach the game board surface 2. The return ball P' that has returned toward the firing bag M9 falls into the recovery path 16. A return ball sensor 17 that detects this is placed in the middle of the recovery path 16, and the output of this return ball sensor 17 is sent to a return ball counter 43 (FIG. 4), which will be described later.

As a result, game balls (return balls) that return to the firing device 9 without reaching the game board surface 2 are not counted as fired balls.

In this embodiment, as will be described later, when the game ball detector 21 detects a game ball that has passed through the passing chuck car 6L or 6R, it drives the variable display 7 to variably display numbers 0 to 9. A random number is generated every predetermined time, its value is determined, and after a predetermined time, a number corresponding to the value of the random number is displayed and the variable display is stopped. As a result of random number judgment, if the last display hits a specific number (for example, 7), the variable winning devices 3L, 3C, and 3R, which are the starting openings, are driven to convert into the second state advantageous to the player, and a predetermined number is entered. When the time has elapsed, the conversion drive is stopped and each variable winning device 3L, 3C.

3R is returned to the first state.

The conversion drive of the variable prize winning device as described above may be continuous or intermittent. In addition, as methods for driving the plurality of variable prize winning devices, there is a method in which all of them are converted and driven at the same time, and a method in which each of the variable prize winning devices is sequentially converted and driven once into two states. According to this method, the variable winning device to be converted circulates and the display is interesting, but when a predetermined number of game balls have won, the variable winning device that is being converted stops, so all the variable winning devices compared to stopping all at once,
The overall change is small and visually desirable.

The variable winning devices 3L and 3C13R close a pair of movable pieces installed on the game board surface to enter a first state in which the game ball cannot win a prize or are difficult to win a prize, and open a pair of movable pieces (thereby causing the game ball to win a prize). It becomes the second state in which it is easy to win or win.

A pair of movable pieces are solenoid 4 located on the back side of the game board.
4 (Fig. 4) to open it and excite it, and close it when the solenoid is demagnetized by turning off the current.

In this embodiment, a variable winning device such as the one described above is used as a starting opening for starting another game, but other winning devices may be used.For example, above the winning opening provided on the game board By making the rod-shaped winning restriction member appear and disappear, the winning opening can be closed to the first place where the game ball cannot win or is difficult to win.
and a second state in which the game ball can win a prize, or a winning hole provided on the game board surface where the game ball cannot win or is difficult to win (first state) and a second state where the game ball can win. A device that is movable between the winning position (second state) and the like can be used.

A starting port sensor 33 (FIG. 4) is provided to detect the game ball that has entered the starting port as described above.
Similar to the above-described shot ball sensor 14, a magnetic sensor having a hole through which a game ball can pass can be used. The output of this sensor is sent to a second control signal generation section 30, which will be described later.

Next, the pinball game machine of the embodiment generates random numbers at predetermined time intervals according to the detection signal from the above-mentioned handle operation detection switch 40, and according to the determination result, sets the above-mentioned variable winning device to the second state. In order to change the probability of appearance of the random value to be converted, the following control means is provided.

As shown in FIG. 4, the control means 41 operates with a first random number generation section 22 as a circuit section that operates according to the detection signal from the game ball detector 21 described above, and determines the value of the generated random number. The first determination unit 23, the variable display 7 and variable winning devices 3L and 3C described above.

The first control signal generating section 24 outputs a control signal for driving and controlling the 3R solenoid 44.

Here, the first determination unit 23 is configured to change the probability that a first random value that converts the variable winning device to the second state will appear when the count value of a counter 29, which will be described later, is equal to or greater than a predetermined number. Ru.

When the game ball detector 21 outputs a detection signal, the first control signal generation unit 24 sends a signal to the variable display 7 to variably display numbers 0 to 9 via the display drive circuit 3I, and after a predetermined time. , the variable display stops at a number according to the result of random number determination. If the display corresponds to a specific number "7", the solenoid 44 is driven via the drive circuit 32 to convert the variable winning devices 3L, 3C, and 3R to a second state advantageous to the player. . Then, when the conditions for terminating the conversion drive are achieved, for example, when a game ball wins or when a predetermined period of time has elapsed, the variable winning devices 3L, 3C, and 3R are configured to return to the first state.

Further, the control means 41 is a circuit section that operates according to the detection signals from the handle operation detection switch 40, the launched ball sensor 14, and the returned ball sensor 17 as described above. A clock section 42 operates in response to a signal, a return ball counter 43 whose count value increases by 1 each time it receives a detection signal from the return ball sensor 17, and an output signal a from the clock section 42 and a return ball counter 43 that increases the count value by one each time it receives a detection signal from the return ball sensor 17. Second and third random number generators 25 and 26 that respectively generate random numbers according to the output signal; second and third determination units 27 and 28 that respectively determine the values of the generated random numbers; A counter 29 counts the number of times the random number has been determined to be a predetermined value by the determining section 27, and when the random number determined by the third determining section 28 is a predetermined value, a display is displayed as a separate game that is started by winning a prize in the starting slot. and a second control signal generating section 30 that controls the variable display device 4 so that the process ends in a predetermined manner.

In this circuit section, the counter 29 counts the number of times the second random number is determined to be a predetermined value, and if that value is a certain number (for example, 2) or more, then the counter 29 receives the counting specific power and returns the first random number. The first random number value or its range that is determined by the determining unit 23 to be a specific display is changed.

The second control signal generating section 30 includes the above-mentioned starting port sensor 33
A signal is sent to the display drive circuit 34 in response to the detection signal, and the variable display device 4 is driven. The starting port sensor 33 detects when a game ball enters any of the variable winning devices 3L, 3C, and 3R, and can use an optical sensor, a microswitch, etc. in addition to a magnetic sensor.

The variable winning device (attacker) 5 is provided with an attacker winning ball sensor 35 and a winning ball counter 36 as means for detecting game balls that have won in the internal winning hole. The winning ball sensor 35 is composed of a sensor similar to the starting port sensor 33, and is arranged in the winning ball discharge path of the attacker. The detection signal of this winning ball sensor 35 is inputted to a winning ball counter 36, and the number of winning balls is counted. Further, a drive circuit 38 is provided to drive a solenoid 37 for driving the attacker door.

In the control means 41 of FIG. 4, when the game ball detector 21 outputs a detection signal, the first random number generation section 22 generates a random number, and the first determination section 23 determines the value. and,
When the value of the random number hits a predetermined number, the first control signal generator 24 stops the display on the variable display 7 in a specific manner as described above, and also controls the starting port in a manner advantageous to the player. The second
Drive converts to state. The probability is, for example, 1/20. That is, in the case of the embodiment shown in FIG. 1, the specific display [7] appears once every 20 times the game ball passes the passing chuck car 6L or 6R, and the variable winning device! f3L, 3G
, 3R are converted to the second state.

When a game ball wins a prize in the variable winning device (starting port in the case of the embodiment) during conversion drive and the starting port sensor 33 outputs, the second
The control signal generating section 30 drives the variable display device 4 for playing another game to start variable display, while also controlling the counter 29.
sends a signal to subtract the counted value by 1.

On the other hand, the timer section 42 starts measuring one hour when a detection signal is given from the handle operation detection switch 40 and a detection signal is given from the shot ball sensor 14, and generates a timing pulse every predetermined time. Consists of a generating circuit. For example, the launcher 9 releases the game ball for 1 minute (60 seconds).
When firing at a rate of 100 in between, the timing section 42
Outputs a timing pulse every ゜6 Xyl (n=1.2, 3.-...) seconds.

In this case, not only the detection signal from the handle operation detection switch 40 but also the detection signal from the launched ball sensor 14 is sent to the timer unit 4.
2 is given to exclude blank hits and to confirm that the iM game ball was fired.

However, the firing ball sensor I4 is placed not at the position shown in Fig. 2, but at a position that detects the game ball at the firing position described above, and the firing operation is possible only when the firing ball sensor I4 detects the game ball. In this case, only the detection signal from the handle operation detection switch 40 needs to be given to the timer 42. In this case, the detection signal from the shot ball sensor 14 is 1.
The solenoid drive circuit is configured to operate only when a detection signal is supplied from the launch ball sensor 14.

The return ball counter 43 increases the count value by one each time the return ball sensor 17 shown in FIG. 3 detects the return ball P°.

The second and third random number generators 25 and 26 generate random numbers in response to timing pulses generated by the timer 42 at predetermined intervals (for example, the above-mentioned 0.6Xn seconds). However, the condition is that the value of the return ball counter 43 is O, and if the counted value is 1 or more, no random number is generated.

For example, if the count value of the return ball counter 43 is "2" and the timer 42 generates a timing pulse every 0.6 seconds, the timing pulse will be passed twice and no random number will be generated). , the second random number generator 25 or the third
The random number generator 26 outputs a signal C that counts down the return ball counter 43. Timing section 42 is 0.6X 2
= If a timing pulse is generated every 1.2 seconds,
The timing pulse only needs to pass once.

The second determining section 27 determines the value of the random number generated by the second random number generating section 25, and if the value matches a predetermined number, it sends a signal to the counter 29 to increment the number of times. If the count value of the counter 29 is equal to or greater than a certain number (eg, 2), the first determination unit 23 sets the probability of a specific display as described above, for example, from 1/20 to 1/10. This increases the number of game balls that enter the variable winning device.

Further, as a result of determining the random number value by the third determining unit 28, if the value hits a predetermined number, the separate game will be ended with a specific result pattern (for example, a jackpot).
The probability of a particular outcome is set to, for example, 1/300. When the result of another game is a jackpot, the second control signal generation unit 30 sends a signal to the drive circuit 34 to stop the variable display device 4 with a jackpot display (for example, “777”), and also sends a signal to the drive circuit 34 to stop the variable display device 4 with a jackpot display (for example, “777”). A signal is sent to the drive circuit 38 to open the door for a certain period of time.

In addition, in the case of a hit or miss other than a jackpot (probability is determined by the range of random numbers set correspondingly)
In this case, the variable display device 4 is stopped at a corresponding display, and in the case of a win, a predetermined number of prize balls are paid out.

In the above control means 41, the first to third random number generation units 22.25.26, the first to third determination units 23.27.2
8 and the first and second control signal generating sections 24 and 30 may be configured as a single random number generating section, a determining section, and a single control signal generating section, respectively. Further, although these can be constructed from known electronic circuits, it is also possible to execute all operations of the above-mentioned control means using a microcomputer.

In that case, the microcomputer detects the game ball detector 21
A first random number is thrown each time the variable prize winning device is detected, and when the value wins the lottery, that is, when it becomes a value that converts the variable prize winning device to the second state, a flag 1 is set. Then, the program outputs a signal for intermittently or continuously converting the variable winning devices 3L, 3C, and 3R to a second state that is advantageous to the player, and stops the conversion drive when the end condition is achieved. be done. Even if flag 1 is set, if the variable prize winning device does not win, the flag generated in the next lottery is set to 2, and the variable winning device is driven to convert until the number of game balls including the carryover ball is won. . Also, if, for example, two game balls win when flag l is set, the flag -
1 and cancels it with the flag 1 generated in the next lottery.

In addition, if the second random number generated in response to the clock signal every predetermined time hits a predetermined value, a flag corresponding to it is set, and when the value reaches a predetermined value (for example, 2), the second random number is set to a predetermined value. 1
Change the probability of a random number hitting. Furthermore, if the third random number generated in response to the detection of one shot ball matches a predetermined value, a flag corresponding to it is set.

By the way, the variable prize winning devices 3L and 3C of the embodiment.

In 3R, the first state is a state in which the pair of movable pieces are closed and the game ball cannot win, but the first state of the variable winning device used in the present invention is that the game ball is difficult to win (the winning is not possible). The situation may be difficult (though not impossible). In that case, even if the variable winning device is in the first state, that is, even when the flag indicating that the first random number has hit the predetermined value is not set, the game ball may win the variable winning device. may occur, but such winning may also occur if the starting port sensor 33
Detected in At that time, the microcomputer sets the flag to -1 and offsets it with the flag 1 generated in the subsequent lottery.

By using a microcomputer and setting flags as described above, it is possible to change the state of the variable prize winning device and execute the result pattern of another game with a predetermined probability. In addition, if the following flag is set while converting the variable winning device to the second state, when playing another game, or when the attacker is open due to the result of another game, etc. , it is possible to memorize it and execute an operation corresponding to the state of the flag after displaying the result of another game or at any other necessary time.

In the illustrated embodiment, the variable winning device is used as a starting port to play another game, but if there is no other game, the third random number generation is simply unnecessary in the above embodiment. , controlling the conversion of the variable prize winning device to the second state based on the first and second random numbers is performed in the same manner.

Although the embodiments have been described above, the present invention is not limited to pachinko gaming machines, but can be applied to smart pole machines, mahjong ball gaming machines, and other pinball gaming machines. Further, when a separate gaming device is provided, any variable display device of the embodiment can be used, and the configuration and arrangement of the starting port can be arbitrary.

[Effect of the invention 1 As described above, in the pinball game machine of the present invention, the first random number generated in response to the detection signal from the game ball detection means arranged on the game board surface is determined to be a predetermined value. When the variable winning device is driven to convert to the second state, the first random number value that converts the variable winning device to the second state appears based on the determination result for the value of the second random number generated every predetermined time. Since the probability is changed, the probability of changing the state of the variable prize winning device is adjusted even if a shot ball is not detected, giving the player the opportunity to win a prize in the variable winning device and earn profits associated with it. can be given equally. Therefore.

Players can enjoy the pinball game regardless of their skill, and the winning rate can be managed in the game hall without the conventional nail adjustment.

In addition, in a pinball game machine that allows separate games, the outcome of the separate game that is started by winning the starting slot is determined by the predetermined R#1@ or by the value of a third random number that is generated as appropriate. By doing so, it is possible to adjust the probabilities of the state change of the starting opening and the result pattern of the different game.
