Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a ball-and-ball game machine such as a pachinko machine, and more specifically, a game ball fired on a game board is disadvantageous to a player in winning. The present invention relates to a ball game machine having a variable winning device formed so as to be convertible between a first state and a second state advantageous to a player.

[Prior Art] In a conventional pachinko gaming machine, a profit (prize ball) is given according to the number of gaming balls entering the variable prize device as described above. There is known a pachinko gaming machine in which a game different from a pachinko game is performed, and a player is given an opportunity to obtain a great profit according to the result. In this type of pachinko gaming machine, a display device that variably displays numbers and pictures is provided on the game board surface as a typical separate game, and a game ball fired on the game board surface wins a winning opening called a starting port. To change the variable prize device called a tulip or an attacker to a state advantageous to the player according to the result mode when the variable display is stopped by the player's stop operation or after a certain time has elapsed. Like that. Furthermore, in order to provide many players with an opportunity to obtain profits from another game, it has been considered that the result form of another game is made to appear based on a preset probability.

[Problems to be Solved by the Invention] However, as described above, even if the result mode of another game that brings great profit to the player appears with a certain probability, the another game starts unless the game ball enters the starting port. No prize in the starting opening is guaranteed. Like the conventional variable winning device, the winning at the starting port is highly dependent on the skill of the player. Also, in the conventional pachinko machine,
Adjusting the nail near the prize device or placing the prize device in a position where it is difficult for the game ball to win, especially for a specific player called a professional, is particularly disadvantageous for players with poor skills, Such a separate game as described above cannot be performed, and as a result, a large difference occurs in the number of prize balls obtained depending on the skill of the player, and there is a problem that the game intended for ordinary people lacks equality. .

Therefore, a ball game machine has been developed in which the number of game balls entering the variable prize device is adjusted according to the probability based on the detection of the shooting ball to equalize the chances of obtaining profits given to the player. A patent application has been filed by a human (Japanese Patent Application No. 1-109685).

When the first random number generated in response to the detection signal from the game ball detection means disposed on the game board surface is determined to be a predetermined value, the ball game machine switches the variable winning device to a disadvantageous game for the player. A first turbulence that converts and drives the variable winning device to the second state based on the determination result of the second random number generated in response to the detection signal from the launching ball detection means by converting and driving the first state to the advantageous second state. The probability of occurrence of a numerical value is changed, and the probability of state change of the variable prize device can be adjusted to evenly give a prize to the variable prize device and an opportunity to obtain profit accompanying it.

By the way, in the current pachinko machine, when the firing handle is operated, a predetermined number (for example, 100
(A) pachinko ball is generally employed. In this case, the sampling of random numbers for winning control as described above can be performed without actually detecting a shooting ball. That is, a random number is sampled each time a launch sphere is detected as described above, and when the random number is set to a predetermined value with a probability of, for example, 1/100, a predetermined value is set for 100 launch spheres. Is generated once, which is equivalent to generating a random number of a predetermined value once in 60 seconds in a pachinko machine equipped with the above-described launching device.

From this viewpoint, the present invention adjusts the number of game balls entering the variable prize device according to a probability based on sampling of random numbers, without actually detecting a shooting ball, thereby providing an opportunity to obtain a profit to be given to a player. It is an object of the present invention to provide a ball game flag that equalizes the flag.

[Means for Solving the Problems] The ball game machine of the present invention is driven so as to fire a predetermined number of ball game balls on a game board surface within a preset time in accordance with a shooting operation of a player. A launching device, a variable winning device configured to be convertible into a first state unfavorable to the player and a second state advantageous to the player with respect to winning of a game ball fired from the firing device, and launching by the player. A launch operation detecting means for detecting an operation; a game ball detecting means arranged on the game board surface; a first random number generated in response to a detection signal from the game ball detecting means; The variable winning device is converted to a second state when the value is a predetermined value, and a second random number is generated at predetermined time intervals in accordance with a detection signal from the firing operation detecting means to generate the second random number. Judge the value of the random number of 2, and according to the judgment result, the variable winning Characterized in that a control means for changing the probability of occurrence of the first random value to convert the location to the second state.

The ball game machine of one embodiment of the present invention further includes, in addition to the above configuration, a second game ball detection means for detecting a game ball waiting to be fired from the launch device, and the second game ball detection means The launching device can be driven only when is detecting a game ball.

In another embodiment, the control means includes: a first random number generation unit that generates a random number in accordance with a detection signal from the game ball detection means; and a predetermined random number in response to a detection signal from the firing operation detection means. A timer for outputting a clock signal, a second random number generator for generating a random number in accordance with the clock signal from the timer, and a first and a second for determining the values of the first and second random numbers. A determination unit; and a control signal generation unit that outputs a control signal for controlling the variable winning device based on a determination result of the first determination unit.

The game ball detecting means has a hole through which the game ball hit on the game board surface can pass, and can be constituted by a passing ball detector for detecting the game ball passing through the hole. Alternatively, a prize hole may be provided at a predetermined position on the game board surface for receiving a game ball, and a sensor for detecting the game ball entered therein may be used.

On the game board surface, there is provided a variable display for variably displaying numbers and the like in accordance with a detection signal from the game ball detection means, and the control means displays the variable display when the value of the first random number is determined to be a predetermined value. It is preferable to drive and control the variable display so as to stop at a specific result mode.

The control means changes the appearance probability of the first random number value for converting the variable winning device to the second state when the number of times that the second random number generated by the random number generation means is determined to be the predetermined value is equal to or more than a predetermined number. It is preferable to configure as follows.

Another aspect of the present invention is a launching device driven to launch a predetermined number of game balls on a game board surface within a preset time in response to a launch operation of a player, and a launching device from the launching device. A starting port for starting another game by winning a game ball, wherein the start port is configured to be convertible into a first state disadvantageous to the player and a second state advantageous to the player with respect to winning of the game ball, In a ball game machine having a separate gaming device for performing, a firing operation detecting means for detecting a firing operation by a player, a game ball detecting means arranged on the game board surface, and a game ball detecting means A first random number is generated in response to the detection signal of (i), and the value of the first random number is determined. When the value of the first random number is a predetermined value, the starting port is converted to the second state and is driven. Generates a second random number every predetermined time according to the detection signal Then, the probability of the first random number that converts the starting port into the second state is changed according to the result of the determination, and the third random number is changed every predetermined time. And determines the third random number value, and when it is a predetermined value,
A control means for controlling another game device so that another game started by winning the start opening ends in a predetermined result mode.

Here, the control means outputs a first random number generating unit for generating a random number in response to a detection signal from the game ball detection means, and a clock signal every predetermined time in accordance with the detection signal from the firing operation detection means. A timer, a second random number generator that generates a random number in response to a clock signal from the timer, and a third random number generator that generates a random number separately from the second random number in response to the clock signal from the timer. A first random number generator, first, second, and third determiners for determining the values of the first, second, and third random numbers, and the starting port is controlled by a determination result of the first determiner. And a second control signal generating unit that outputs a control signal for controlling another gaming machine based on the result of the determination by the third determining unit. be able to.

In addition, as another game, for example, a variable display device for variably displaying a plurality of numbers, characters, or graphics is provided on a game board surface, and when a game ball wins at the starting port, a number or the like is displayed by a signal from the control means. The variable display is performed, and the variable display is stopped in a result mode corresponding to the value of the third random number. Furthermore, when another game is completed in a specific result mode, the variable or variable winning device arranged on the game board may be converted to a state advantageous to the player.

[Operation] In the ball game machine of the present invention, when a player performs a shooting operation (for example, a steering wheel operation), a predetermined number of game balls are fired from a firing device within a set time. At this time, when the game ball detection means detects a game ball fired on the game board surface, the control means generates a first random number in accordance with the detection signal, and when the value of the random number is determined to be a predetermined value, Then, the variable winning device is converted and driven to the second state. This conversion drive
Not only the case where the second state is continued, but also the case where the first state and the second state are alternately repeated. The conversion drive of the variable prize device ends when the predetermined time elapses, or when a predetermined number of game balls have won, for example, returns the variable prize device to the first state.

On the other hand, when the player performs a firing operation, a firing operation detecting means (for example, a switch that is turned on in conjunction with a steering wheel 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 occurrence of the first random number value for converting the variable winning device to the second state based on the determination result. Thereby, the number of game balls entering the variable winning device can be adjusted.

Further, in a ball game machine equipped with a variable winning device as a starting port for starting a game different from a normal ball game when a game ball fired on the game board surface wins, the control means is a predetermined A third random number is generated every time, and when the random number is determined to be a predetermined value, the other gaming device is controlled such that another game started by winning a prize at the starting port ends in a predetermined result mode. That is, when a game ball wins at the starting port during the conversion drive as described above, another game is started. The result mode is determined by the value of the random number, and the other game ends in the result mode.

As mentioned above, in the case of a ball game machine that can play another game,
By determining the result mode of another game started by the conversion of the starting port to the second state and the winning in the starting port with a probability that a random number generated every predetermined time takes a predetermined value, the player can be given to the player. In the game field, a prize at the starting port and an opportunity to obtain a profit in accordance with the result mode of another game are equally given, and the prize rate can be managed without a conventional nail adjustment in a game hall.

The probability that the random number takes a predetermined value is determined, for example, by setting the time during which a predetermined number of game balls are fired from the launching device by the player's firing operation to 60 seconds, and the random number having the predetermined value is set to one time within the set time. In the case where random numbers are sampled, the probability is 1/60 if random numbers are sampled every 1 second, 1/12 if random numbers are sampled, and 1/12 if random numbers are sampled every 60 seconds. The probability is 1/1. By generating a random number having a predetermined value at every predetermined time in this manner, equivalent control can be realized without detecting a shooting sphere.

As described above, in the present invention, the second random number for changing the probability of the appearance of the first random number value that converts the variable winning device into the second state advantageous to the player is determined by the detection signal of the shooting sphere. Instead, it is generated every predetermined time in accordance with the detection signal of the shooting operation, so that the conventional shooting ball detection means and a counter for counting the number of shooting balls are unnecessary.

In one embodiment of the present invention, in addition to the game ball detecting means arranged on the game board surface, the game device further includes a second game ball detecting means for detecting a game ball waiting to be fired from the launching device, and the game ball detecting means detects the game ball. The firing device can be driven only when it is detected. For this reason, the detection signal from the game ball detection means is given to the drive unit of the launching device, and the drive unit operates only when the detection signal is given from the game ball detection means. This allows
A blank shot by the player can be excluded, and a correct firing operation can be realized.

Embodiment FIG. 1 is a front view of a pachinko gaming machine according to one embodiment of the present invention.

The pachinko gaming machine 1 is configured such that a game ball fired on the game board surface 2 wins a start port to play another game, and the game board surface 2 has a first state where a game ball cannot be won. A plurality of variable winning devices 3L, 3C, 3R that are converted to the winning second state are arranged as starting ports. Further, in the center of the game board surface 2, a variable display device 4 is arranged as another gaming device, and below it, a variable winning device 5 provided with a door that opens when a result of another game becomes a specific display mode is provided. Have been.

The variable display device 4 has a plurality (for example, three) in a rectangular window.
Are arranged in a seven-segment LED (light emitting diode) display for variably displaying the numbers of the above. Each LED display has a display drive controlled by an output signal from a control signal generator 30 shown in FIG. The circuit 34 is connected. The display may display characters, figures, and the like, in addition to numbers.

The variable winning device 5 is referred to as an attacker, and has a substantially identical door openably and closably mounted on the front side of an opening provided on an upper portion of a trapezoidal front plate, and has a winning opening in the opening. The door of the variable winning device 5 is opened and closed by a driving mechanism using a solenoid mounted on the back side of the front plate as a power source.

On the left and right sides of the variable display device 4, a passing chucker 6 is provided as a kind of a winning hole into which a game ball fired on the game board surface 2 enters.
L and 6R are arranged. Each chucker 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 for detecting a game ball passing through the hole with an appropriate cover. Passing ball detector, game board surface 2
The game ball emitted above is provided as a game ball detector 21 (FIG. 4) for detecting when a game ball has passed through a specific area. The game balls (winning balls) may be provided and detected by a suitable detector.

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

A number of nails are arranged on the game board surface 2 as guide means for guiding the fired game balls to the upper part of the variable winning device or the like, while a firing handle 20 is provided on the lower right side of the front face. When the player operates the game ball, a game ball is fired from a firing device, which will be described later, attached to the back side of the game board, and moves along the guide rail 8 on the game board surface 2.

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

As the game ball launching device, for example, the one shown in FIG. 2 is used. The launching device 9 uses an electromagnetic force to move the plunger 10
And a ball launching portion 11 including a solenoid that causes the game ball P to fly out by projecting the ball, and a hitting ball guide portion 12 provided on the plunger projecting side. The hitting ball guide portion 12 is formed of a cylindrical member having a notch at its tip for feeding the game ball P, and has a pair of guides on its inner bottom surface for guiding the game ball P hit by the tip of the plunger 10 forward. It has parallel ridges 13. The game ball P sent into the hitting ball guide 12 is:
It stops at a position (firing position) where it comes into contact with the tip of the plunger 10 on the ridge 13, and at the time of firing, it is repelled by the protruding plunger 10 by the bias of the solenoid and fired forward.

In order to detect each game ball P fired from the above-mentioned launching device 9, a launching ball sensor is provided in front of the launching device 9.
14 is arranged. The shooting sphere sensor 14 is formed of a magnetic sensor having a hole through which the shot game ball P can pass, and the output is sent to a timer 42 (FIG. 4) described later.

The launching ball sensor 14 is not limited to being placed in front of the launching device 9 as described above, but may be placed at the launching position of a game ball. In that case, when the launching ball sensor 14 detects a signal to activate the launching device 9 while detecting a game ball,
Outputs a launch sphere detection signal. According to this method, detection is performed only when the firing device 9 is operated in a state where the game ball is at the firing position, so that it is possible to reliably detect that the game ball has been correctly fired.

The game ball P fired from the firing device 9 passes through the shooting ball passage 15 as shown in FIG. 3 and rises along the guide rail 8 toward the game board surface 2, but is fired without reaching the game board surface 2. The returning ball P 'returning to the device 9 is a recovery path.
Fall to 16. The return ball sensor 17 that detects this is collected
The output of the return ball sensor 17 is provided in the middle of 16 and is sent to a return ball counter 43 (FIG. 4) described later. Thus, a game ball (return ball) that has returned to the launch device 9 without reaching the game board surface 2 is not counted as a launch ball.

In this embodiment, as described later, when the game ball detector 21 detects a game ball that has passed through the passage chucker 6L or 6R,
While the variable display 7 is driven so as to variably display the numbers 0 to 9, a random number is generated every predetermined time and its value is determined. After a predetermined time, a number corresponding to the value of the random number is displayed. Stop variable display. As a result of the random number determination, when the last display corresponds to a specific number (for example, 7), the variable winning devices 3L, 3C, and 3R, which are starting ports, are converted into the second state advantageous to the player and driven. When the time has elapsed, the conversion drive is stopped and each of the variable winning devices 3L, 3C, 3R is returned to the first state.

The conversion driving of the variable winning device as described above may be either continuous or intermittent. In addition, as a method of driving a plurality of variable winning devices, there is a method in which all the winning devices are simultaneously converted and driven, and each winning device is sequentially converted once and driven into two states. According to this method, the variable winning device to be converted circulates, and while the display is interesting, the variable winning device that is being driven for conversion is stopped when a predetermined number of game balls have won, so that all of the plurality of variable winning devices are changed. Compared to the case of stopping all at once, the overall change is small and visually desirable.

The variable prize devices 3L, 3C, and 3R are in a first state in which a game ball cannot be won or hard to win by closing a pair of movable pieces installed on the game board surface, and the game ball is opened by opening an integral movable piece. It is in the second state where a prize can be won or a prize can be easily won. The pair of movable pieces are configured to open by energizing a solenoid 44 (FIG. 4) disposed on the back side of the game board by exciting the solenoid, and to close when the energization is stopped and the solenoid is demagnetized.

In the present embodiment, the above-described variable winning device is used as a starting port for starting another game, but another winning device may be used. For example, a bar-shaped winning control member is made to protrude and emerge above a winning opening provided on a game board surface, so that the gaming ball cannot win or hardly wins the winning opening.
The state is converted into a second state in which the game ball can be won, or a winning port provided on the game board is provided with a position (first state) where the game ball cannot win or is difficult to win (the first state). For example, a member that can be freely moved between a winning position (second state) and the like can be used.

A starting port sensor 33 (FIG. 4) is provided to detect a game ball entering the starting port as described above.
Similar to the above-described shooting 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 generator 30 described later.

Next, the ball game machine of the embodiment generates a random number every predetermined time in accordance with the detection signal from the steering wheel operation detection switch 40, and sets the variable winning device to the second state according to the determination result. In order to change the probability of occurrence of the random value to be converted, the following control means is provided.

As shown in FIG. 4, the control means 41 is a circuit section that operates in accordance with a detection signal from the game ball detector 21 described above.
A first random number generating unit 22, a first determining unit 23 for determining the value of the generated random number, the variable display 7 and the variable prize device described above.
A first control signal generator 24 that outputs a control signal for controlling the driving of the solenoids 44 for 3L, 3C, and 3R. Here, the first
The determination unit 23 is configured to change the probability of occurrence of a first random number value that converts the variable winning device to the second state when the count value of a counter 29 described later is equal to or greater than a predetermined number.

When the game ball detector 21 outputs a detection signal, the first control signal generator 24 controls the variable display 7 via the display drive circuit 31.
And a signal for variably displaying the numbers 0 to 9 is sent, and after a predetermined time, the variable display is stopped at a number corresponding to the result of the random number determination. If the display hits a specific number "7",
By driving the solenoid 44 via the drive circuit 32, the variable winning devices 3L, 3C, 3R are converted to the second state advantageous to the player. Then, the variable winning devices 3L, 3C, 3R are configured to return to the first state when a condition for ending the conversion drive is achieved, for example, when a game ball wins or when a predetermined time has elapsed.

Further, the control means 41 is provided with the aforementioned steering wheel operation detection switch.
40, a circuit section that operates in response to the detection signals from the launching ball sensor 14 and the return ball sensor 17, a timing unit 42 that operates in response to the detection signals from the handle operation detection switch 40 and the launch ball sensor 14, and a return ball. A return ball counter 43 whose count value increases by one each time a detection signal from the sensor 17 is received, and a second which generates random numbers in accordance with an output signal a from the timer 42 and an output signal b from the return ball counter 43, respectively. And third random number generating units 25 and 26, second and third determining units 27 and 28 each determining a value of the generated random number, and a second determining unit
Counter that counts the number of times that the random number is determined to be the predetermined value in 27
29 and when the random number determined by the third determination unit 28 is a predetermined value,
A second control signal generation unit that controls the variable display device so that the display as another game started by winning the start opening ends in a predetermined result mode.

In this circuit section, the counter 29 counts the circuit in which the second random number is determined to be a predetermined value. If the value is equal to or more than a predetermined number (for example, 2), the counter 29 receives the count output and performs the first determination. The first random value determined by the unit 23 to be the specific display or the range thereof is changed.

The second control signal generator 30 sends a signal to the display drive circuit 34 in accordance with the detection signal of the above-described starting port sensor 33, and drives the variable display device 4. The starting port sensor 33 is a variable winning device.
When a game ball enters any of 3L, 3C, and 3R, it is detected, and in addition to a magnetic sensor, an optical sensor, a microswitch, or the like can be used.

In the variable winning device (attacker) 5, an attacker winning ball sensor 35 and a winning ball counter 36 are provided as means for detecting a ball game ball winning the internal winning opening. Winning ball sensor
Reference numeral 35 denotes a sensor similar to the start-up opening sensor 33, and is disposed in a winning ball discharge passage of the attacker. This winning ball sensor
The detection signal 35 is input to the winning ball counter 36, and the number of winning balls is counted. Further, a drive circuit 38 for driving a solenoid 37 for driving the attacker door is provided.

In the control means 41 of FIG. 4, when the ball game ball detector 21 outputs a detection signal, the first random number generation unit 22 generates a random number, and the first determination unit 23 determines the value. When the value of the random number reaches a predetermined number, the first control signal generator 24 stops the display of the variable display 7 in a specific manner as described above, and To the second state, which is advantageous for The probability is, for example, 1/20. That is, in the case of the embodiment of FIG.
A specific display "7" at a rate of one game ball after passing the 6R 20 times
Appears, and the variable winning devices 3L, 3C, 3R are converted to the second state.

Variable winning device during conversion drive (starting port in the case of the embodiment)
When the game ball wins and the starting port sensor 33 outputs, the second
Of the variable display device 4 for performing another game
To start variable display, and sends a signal to the counter 29 to decrement the count value by one.

On the other hand, when a detection signal is given from the steering wheel operation detection switch 40 and a detection signal is given from the shooting sphere sensor 14, the timing unit 42 starts a clock measurement and generates a pulse every predetermined time. It is composed of a generating circuit. For example, the launching device 9 moves the game ball for one minute (60 seconds)
When firing at a rate of 100, the timer 42 calculates 0.6 × n (n
= 1,2,3, ...) A timing pulse is output every second.

In this case, not only the detection signal from the handle operation detection switch 40 as the firing operation detecting means but also the detection signal from the firing sphere sensor 14 as the firing sphere detecting means is given to the timer 42, which excludes the blank hit. This is to confirm that the game ball has been fired.

However, the shooting ball sensor 14 is not located at the position shown in FIG. 2 but at a position for detecting a game ball at the above-described shooting position (that is, waiting for firing from the firing device 9). If the shooting operation is enabled only when the game ball is detected, the timer 42 only needs to be provided with the detection signal from the steering wheel operation detection switch 40. In this case, the shooting sphere sensor 14 is actually a game sphere detecting unit that detects a game sphere waiting for firing, instead of a shooting sphere. The detection signal from such a game ball detection means is transmitted to the reflection device 9.
, And the solenoid drive circuit is configured to operate only when a detection signal from the game ball detection means is given.

The return ball counter 43 increments 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 accordance with timing pulses generated by the timer 42 every predetermined time (for example, 0.6 × n seconds). However, return ball counter
On condition that the value of 43 is 0, if the count value is 1 or more, no random number is generated.

For example, when the count value of the return ball counter 43 is “2”, if the timer 42 generates a timing pulse every 0.6 seconds, the timing pulse is passed twice (no random number is generated). The second random number generator 25 or the third random number generator 26 outputs a signal c for counting down the return ball counter 43. If the timing unit 42 generates a timing pulse every 0.6 × 2 = 1.2 seconds, the timing pulse may be passed once.

The second determination unit 27 determines the value of the random number generated by the second random number generation unit 25, and if the value reaches a predetermined number, sends a signal to the counter 29 to add the number.
If the count value of the counter 29 is equal to or more than a certain number (for example, 2), the probability that the first determination unit 23 will make the specific display, for example, from 1/20 to 1/10 as described above. As a result, the number of game balls entering the variable winning device increases.

Further, as a result of determining the random number value by the third determination unit 28, if the random number value reaches a predetermined number, another game is terminated in a specific result mode (for example, a big hit).
The probability of a particular outcome mode is determined, for example, by a factor of 300. When the result mode of the separate game is a big hit, the second control signal generator 30 sends a signal to stop the variable display device 4 at the big hit display (for example, “777”) to the drive circuit 34 and the variable winning device 5 A signal is sent to the drive circuit 38 to open the door for a certain period of time.

In the case of a hit or a miss other than a big hit (the probability is determined by the range of the correspondingly set random number value), the variable display device 4 is stopped at the corresponding display, and in the case of a hit, a predetermined number Pay out prizes.

In the control means 41, the first to third random number generation units
22, 25, 26, first to third determination units 23, 27, 28 and first,
Each of the second control signal generators 24 and 30 may be configured as a single random number generator, a determination unit, and a control signal generator.
These can be constituted by known electronic circuits, but it is also possible to execute all the operations of the control means by a microcomputer.

In that case, the microcomputer is a game ball detector 21
Every time is detected, the first random number is assigned, and when the value is determined to be a lottery, that is, when the variable winning device is converted to the second state, the flag 1 is set. The variable winning devices 3L, 3C, and 3R are programmed to output a signal for intermittently or continuously converting and driving the variable winning devices 3L, 3C, and 3R to the second state advantageous to the player, and to stop the conversion driving when the end condition is achieved. You. If the variable prize device does not win even if the flag 1 is set,
With the flag generated in the next lottery set to 2, the variable prize device is converted and driven until the number of game balls plus the carryover is won. When two game balls are won when the flag 1 is standing, the flag is set to -1 and the flag is offset with the flag 1 generated in the next lottery.

When the second random number generated in response to the clock signal for each predetermined time hits a predetermined value, a flag corresponding thereto is set, and when the value becomes a predetermined value (for example, 2), the first random number is set. Try to change the probability of random numbers. Further, when the third random number generated in response to the detection of the shooting sphere hits a predetermined value, a flag corresponding thereto is set.

By the way, the variable winning devices 3L, 3C, and 3R of the embodiment change the state in which the game ball cannot be won by closing the pair of movable pieces in the first state.
Although the state is set, the first state of the variable winning device used in the present invention may be a state where it is difficult for a game ball to win (winning is not impossible but difficult). In this case, even when the variable winning device is in the first state, that is, when the flag indicating that the first random number has reached the predetermined value is not set, the game ball wins the variable winning device. However, such a prize is also detected by the starting port sensor 33. At this time, the microcomputer sets the flag to −1 and cancels the flag 1 generated in the subsequent lottery.

By using the microcomputer and setting the flag as described above, the state conversion of the variable winning device and the result mode of another game can be executed with a predetermined probability. When the next flag is set when the variable winning device is changed to the second state, when another game is being played, or when the attacker is open according to the result mode of another game, etc. After the display of the result of another game, it is possible to execute an operation according to the state of the flag when necessary or otherwise.

In the illustrated embodiment, the variable winning device is used as a starting port in order to perform another game. However, if there is no separate game, only the third random number generation is unnecessary in the above embodiment. Controlling the conversion of the variable winning device to the second state based on the first and second random numbers is similarly performed.

Although the embodiments have been described above, the present invention is not limited to the pachinko game machines, but can be applied to smart ball machines, sparrow ball game machines, and other ball game machines. In the case of providing a separate game device, any device other than the variable display device of the embodiment can be used, and the configuration and arrangement of the starting port are also arbitrary.

[Effects of the Invention] As described above, in the ball game machine of the present invention, when the first random number generated according to the detection signal from the game ball detection means arranged on the game board surface is determined to be the predetermined value The variable prize device is driven to be converted to the second state, and the variable prize device is set to the second state based on a determination result for the second random number generated every predetermined time in accordance with the detection signal from the firing operation detecting means. Since the probability of occurrence of the first random number value to be converted is changed, the probability of the state conversion of the variable prize device can be adjusted without detecting the shooting sphere, and the variable prize device can be controlled by the player. The opportunity to win a prize and the accompanying profit can be given equally. Therefore, the player can enjoy the ball game regardless of the skill of the player, and can manage the winning rate without adjusting the conventional nails in the game hall.

Further, in a ball game machine capable of performing another game, a result mode of another game started by winning in the starting opening is determined at predetermined time intervals or by a value of a third random number appropriately generated. Then, the probability of the state conversion of the starting port and the result mode of another game can be adjusted.
