Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine which typifies a pachinko machine and shoots a game ball to play a game. This allows the game shop to make adjustments without making any adjustments.

[0002]

2. Description of the Related Art A pachinko machine is well known as a typical game machine that shoots a game ball and plays a game. In this pachinko machine, an innumerable obstacle nail is implanted on the surface of the game board, By finely adjusting the angle intervals of the obstacle nails, the flow direction of the hit ball is changed subtly, and thereby the winning probability of the hit ball is adjusted.

[0003]

However, a fine technique is required to finely adjust the obstacle nail, and a skill is required to acquire this technique. In addition, in the game store, the ratio of profits to the player for each pachinko machine (so-called ball-out rate, divisor, base value, etc.) is assumed, and the obstacle nail is adjusted for each pachinko machine according to this ratio. For example, the base value (normal return rate) is a normal game state (base game state) excluding a game (special game or jackpot game) in a state in which a variable winning device such as an attacker is opened to significantly increase the winning probability. ) Is the ratio of the number of prize balls discharged (the number of balls that are beneficial to the player) and the number of effective launch balls (the number of balls that are beneficial to the game store). Therefore, for example, if the base value is "46",
In the normal game state, the player shoots 100 balls to play the game, and as a result, 46 prize balls can be won. If the base value is high, the number of prize balls is relatively large relative to the number of balls shot even if a special game is not performed, so the game continues for a relatively long time relative to the number of balls borrowed. On the contrary, when the base value is low, the number of prize balls is relatively small with respect to the number of balls shot, so the game ends in a short time for the number of balls borrowed. Therefore, the game store sets the base value of each pachinko machine according to the model of the pachinko machine and the business policy. Then, if the base value is set to a predetermined numerical value in advance, the obstacle nail related to winning must be adjusted according to this numerical value. However, the adjustment of the obstacle nail is delicate, and a large difference often occurs between the preset base value and the actual business result. The fact that this difference is large means that it was not possible to operate according to the sales policy, which is inconvenient for operation. Therefore, there has been a demand for the development of a gaming machine capable of adjusting the balance between the profit of the game shop and the profit of the player without adjusting the obstacle nail.

[0004]

The present invention has been proposed in view of the above, and has a game board (3) having a game section (5) having a winning area (eg, a winning opening 43), and the above game board. A ball ejecting device (17) capable of ejecting a prize ball based on the hitting of a ball into the winning region of (3), and a specific winning region (for example, the first variable winning device 7) provided on the game board (3).

And a variable prize device (for example, a second variable prize device 9) which is provided on the game board (3) and can be converted into a first state that is disadvantageous to the player and a second state that is advantageous to the player.
A variable prize winning device operating condition forming means (for example, second variable winning device operating condition forming means 72) that forms an operating condition of the variable winning device (9) by the specific winning signal from the specific winning signal generating means (30), and a player. Special game right generation condition formation rate setting means (78) for setting the right generation condition formation rate of special games performed under favorable game conditions, and game disadvantage detection means (for detecting the disadvantage required for the player to play the game) For example, the effective firing ball number calculation means 51), a game profit detection means (for example, base value calculation means 52) for detecting a profit obtained by the player as a game result, and the game disadvantage detection means (51).
Ordinary return rate detecting means (for example, base value calculating means 52) for obtaining the ordinary return rate of the profit to the player from the disadvantage signal from the above and the profit signal from the above-mentioned game profit detecting means (52).
And a normal return rate comparison means (for example, base value comparison determination means 53) for comparing the predetermined normal return rate with the return rate obtained from the game result by the normal return rate detection means (52), and the normal operation Based on the comparison result of the return rate comparison means (53), the ball return device (17) intervenes in the control of the prize ball discharge operation to bring the normal return rate to the player close to the set normal return rate. The game machine (1) is provided with a correction means (for example, the prize ball number determination means 62).

[0005]

When a game ball is shot and a game is played, the normal return rate of the profit to the player is detected by the normal return rate detection means from the disadvantage signal from the game disadvantage detection means and the profit signal from the game profit detection means. Is calculated, and the normal return rate comparison means compares the normal return rate with a predetermined normal return rate. Then, when it is determined that the normal return rate calculated by the normal return rate detecting means is higher than the predetermined normal return rate,
By reducing the number of prize balls discharged by the normal return rate correction means, the actual normal return rate is increased. On the other hand, when it is determined that the normal return rate calculated by the normal return rate detecting means is lower than the predetermined normal return rate, the normal return rate correcting means increases the number of prize balls discharged. , The actual normal return rate can be suppressed.

[0006]

For example, a firing rod having a resilient portion at the tip may be rotated by driving a motor or a rotary solenoid, or may be one that causes the resilient portion at the tip to reciprocate linearly by driving a plunger solenoid.

The batted ball shot by the batted ball launching device 11 reaches the upper end portion in the game section 5 from the launch rail 21 through the guide rail 4 and is used for an actual game, but reaches the game section 5. It acts on the launch ball sensor 22 on the way. The launch ball sensor 22 detects a disadvantage required by the player and sends a disadvantage signal, and detects a hit ball emitted by the hit ball launching device 11 and sends a signal to an electric control device 23 described later. Any structure may be used as long as it has a function to perform. For example, a photo sensor type detector, a non-contact type detector or the like may be provided so as to face the launch rail 21, and the passage of a hit ball may be detected by the detector.

Further, the batted ball shot by the batted ball launching device 11 does not always enter the game section 5 and is used for a game, and may return from the middle to become a foul. For this reason, a foul ball sensor 25 is provided in the middle of a foul ball collection path 24 that extends downward from the upper end of the slope of the launch rail 21 and communicates with the lower plate 13. A foul ball is detected by 25 and a foul signal is sent to the electric control device 23. The foul ball sensor 25 is

In this embodiment, the number of balls passing through the winning gates 8, 8 provided in the game section 5 is collected as specific game data, and the first variable winning device 7 is taken by the player. It is used to determine the condition for converting and driving from the disadvantageous first state to the advantageous second state for the player. Therefore, gate passing ball detectors 26, 26 for detecting a passing ball which the hitting ball passes from the upper side to the lower side and sending a signal to the electric control device 23 are provided in the respective winning gates 8, 8 (see FIG. 4). ). That is, the gate passing ball detector 26 functions as a specific game data collecting means for collecting the number of gate passing balls as specific game data related to the player playing a game.

It should be noted that the ball that has flowed down in the game section 5 passes through the winning gate 8 and wins, and after being detected by the gate passing ball detector 26, this ball passes through the winning gate opening 8 and the gaming section 5 again. Run down. Therefore, the winning balls based on the winning balls that have passed through the winning gate 8 are not discharged. Further, the winning gate 8 may have any configuration as long as it can detect a hit ball by the gate passing ball detector 26 and send a signal, and the structure and the mounting position of the gate passing ball detector 26 are not limited, and the detected hit ball is detected. May be taken in as a prize ball and discharged as a prize ball.

The number of balls passing through the winning gate 8 is displayed on the gate passing ball number display 10, and the number of passing balls moves the first variable winning device 7 to the second state. When the first variation winning device 7 is converted to the second state under the control of the electric control device 23, which will be described later, and satisfies the determination condition for conversion, the number of balls passing through the gate is once reduced to zero, and then again. It is intended to display the integrated value of the number of balls passing through the gate. The gate passing ball number display 10 shown in the drawing is constituted by a 7-segment display.

The first variable winning device 7 is a winning device having a structure capable of converting a first state, which is disadvantageous to the player, and a second state, which is advantageous to the player. As shown in FIG. 5, the first variable winning device 7 shown in the drawing has a pair of left and right movable members 29, 29 axially mounted in an upper open pocket frame 28 provided on the surface of the mounting board 27. By rotating the movable members 29, 29 by driving an electric drive source such as a solenoid (not shown) provided on the back side of the movable members 29, 29, the movable members 29, 29 are substantially upright and the interval between the upper ends is narrow, resulting in a hit ball. It is configured so that it can be converted into a first state in which it is difficult to enter and a second state (FIG. 5) in which the upper ends of the movable members 29, 29 are tilted outwardly to widen the upper end intervals and a ball can easily enter.

Further, in this embodiment, the inside of the first variable winning device 7 is set as a specific winning area, and a hit ball hit in the first varying winning device 7 is detected to generate a specific winning signal. The special symbol starting winning detector 30 as the specific winning signal generating means is provided so as to face the ball passage in the first variable winning device 7 (see FIG. 4). The specific winning signal emitted by the special symbol starting prize winning detector 30 is supplied to the electric control device 23, and based on the input of the specific winning signal, the special symbol display device 6 operates. is there. That is, the specific winning signal issued based on the special symbol start winning detector 30 detects the specific winning ball,
The special symbol display device 6 becomes the starting condition.

Accordingly, when the hit ball is won when the first variable winning device 7 is in the first state or the second state, the special symbol starting winning detector 30 as the specific winning signal generating means detects the winning ball and electrically. A specific winning signal is sent to the control device 23, the hit ball that has won is processed as a winning ball, the ball ejecting device 17 operates, and a predetermined number (7 in this embodiment) of balls on the ball supply tray 15 are prize balls. Is discharged. In this way, when the hit ball is won in the first variable winning device 7, a predetermined number of award balls are given, and the same award is given based on the specific award signal from the special symbol starting award detector 30. However, when the first variable winning device 7 is in the second state, the winning probability of hitting the ball is higher than in the first state. Therefore, when the first variation winning device 7 is converted to the second state, the return rate to the player is increased.

Further, in this embodiment, as a privilege of winning in the first variable prize device 7, another game can be played by the special symbol display device 6, and when the prize mode is formed in this another game, the prize is won. A special game right with a very high probability is generated.

The special symbol display device 6 converts and displays symbols (numerals) such as symbols and numbers at a speed that cannot be discerned with the naked eye, and presets a stop display mode by a combination of symbols when the conversion display is stopped. If it is in a certain mode, a privilege is given to the player. The special symbol display device 6 shown in the drawing is a display device 31a, 31b, in which a large number of LEDs are arranged vertically and horizontally and numbers and the like can be scrolled vertically.
31c are attached to the substrate 32, and three cases are provided side by side in the case 33. When the special symbol display device 6 is activated by the signal from the electric control device 23, the three display devices 31a, 3
The numbers "0" to "9" are converted and displayed at high speed on 1b and 31c, respectively, and after a predetermined time elapses, the converted display on each display unit 31 is sequentially stopped. And the three indicators 31
The combination mode of the numbers displayed on a, 31b, 31c is a prize mode, for example, "3,3,3", "5,5,5",
If it is "7, 7, 7", a special game right is generated. In addition, as will be described later, the probability that the prize mode is formed is configured in this embodiment so that it can be appropriately selected from the probabilities of several stages and set in advance.

The special symbol display device 6 is not limited to the above-mentioned structure, and may have any structure as long as it can convert and display a plurality of identification symbols at an unrecognizable speed.
For example, as in the special symbol display device 6'shown in FIGS. 7 and 8, the drums 34a, 3 having a plurality of symbols written on the outer peripheral surface thereof.
4b and 34c may be rotated by driving a pulse motor.

In the special game, the second variable winning device 9 is changed from the first state which is disadvantageous to the player to the second state which is advantageous to the player.
By converting into a state, a game condition that is advantageous to the player is established, and the game is performed until a predetermined ending condition is established.

The second variable prize device 9 shown in FIG. 9 is a so-called attacker, which is a variable prize device, and the mounting board 3
5, a horizontally long ball entrance 36 is opened as a winning area, a horizontally long door member 37 is rotatably attached to the ball entrance 36, and a front surface communicates with the ball entrance 36 on the back side of the mounting substrate 35. 38, a continuous winning opening 39 and general winning openings 40, 40 are provided in the concave chamber 38, and a solenoid (not shown) is provided as an electric drive source on the back side of the mounting substrate 35. The door member 37 is opened and closed by driving so as to be converted into a first state in which a hit ball is not accepted and a second state in which a hit ball is easily accepted. That is, when the solenoid is demagnetized, the door member 37 is biased by a spring or the like.
Stands up and closes the ball entrance 36 to keep the ball from being received (the first state which is disadvantageous to the player), and when the solenoid excites the signal from the electric control device 23, the door member 37 moves the upper end forward. The ball entrance 36 is opened by pivoting in the direction of tilting to the second state (the state shown in FIG. 9) in which it is easy to receive a hit ball. Also, a counting detector 41 that detects all the balls that have won the second variable winning device 9 and sends a signal to the electrical control device 23, and an electrical control device that detects the balls that have won the continuous winning opening 39. 23 is provided with a continuation detector 42 that sends out a continuation signal. In addition, the second variable winning device 9,
The present invention is not limited to the so-called attacker type described above, and may have any configuration as long as it can be converted into a first state that is disadvantageous to the player and a second state that is advantageous to the player. For example, the state of receiving a hit ball may be changed by rotating a pair of left and right movable members.

The special game is performed by converting the second variable winning device 9 from the first state, which is disadvantageous to the player, to the second state, which is a game for the player, and whether a predetermined time (for example, 28 seconds) elapses. Alternatively, one cycle is defined as one of the conditions until a predetermined number (for example, 10) of hit balls is won, and the cycle is updated on the condition that the hit balls enter the continuous winning opening 39 during this cycle. However, this cycle can be updated up to a predetermined number of times (for example, 16 times).

Next, the game will be described, and the control operation mainly related to the base value control will be described with respect to the electric control device 23 having a microcomputer structure for controlling the game. When the player operates the hitting ball launching device 11 by operating the shooting operation handle 12, one ball introduced from the ball supply tray 15 is shot and supplied to the upper part in the game section 5 for an actual game. Be served. In this way, the hitting ball launching device 11 launches balls one after another (for example, 10 minutes per minute).
Then, the launch ball sensor 22 detects one ball and sends a launch ball signal to the effective launch ball number calculating means 51 of the electric control device 23 each time, and when the hit ball becomes a foul, Every time the foul ball sensor 25 detects a foul ball, the foul ball signal is sent to the effective firing ball number calculation means 51.
To send to.

Upon receiving the launch ball signal and the foul ball signal, the effective launch ball number calculating means 51 calculates the effective launch ball number based on these signals and sends the calculated value to the base value calculating means 52. The base value calculation means 52
To calculate the actual base value. Therefore, by comparing the calculated base value (current base value) with a preset reference base value in the base value comparison / determination means 53, it is possible to determine whether or not the operation of the gaming machine 1 is on schedule. You can

When the hit ball fired in the game section 5 hits an obstacle nail and flows down while changing the direction of the hit, and when this hit ball passes through the winning gate 8 and wins, the gate passing ball detector 26
Detects the gate passing sphere and sends a gate passing sphere detection signal to the electric control device 23.

When the electric control unit 23 receives the gate passing ball detection signal, the gate passing ball number counting means 54 adds "1" to the gate passing ball number, and the ball number signal corresponding to the counted gate passing ball number. Is supplied to the gate passage sphere number display control means 55, and the gate passage sphere number display control means 55 operates the gate passage sphere number display 10 to visually display the number of gate passage spheres.

On the other hand, the gate passing ball number counting means 54 also sends a ball number signal to the ordinary electric accessory opening / passing number determining means 56, and the ordinary electric accessory releasing / passing number determining means 56 is provided therein. Whether the preset memory number for comparison and determination (an arbitrary natural number, for example, "3") matches the gate passing ball number corresponding to the ball number signal supplied from the gate passing ball number counting means 54. The normal electric accessory opening passing ball number determination means 56 always determines whether or not. Then, when the number of balls passing through the gate coincides with the memory number for comparison and determination, the normal electric auditors product opening passage number judging means 56 causes the ordinary electric auditors driving control means 5 to operate.
7, the drive control command is sent to the normal electric auditors product driving control means 57, and the first variable winning device 7 is set to the second.
It is converted into a state and driven.

That is, in this embodiment, the number of gate passing balls is set as the specific game data related to the player playing the game, and the game data collected by the gate passing ball detecting means 26 is predetermined. Based on whether or not the condition is met (whether or not the number of memory for comparison determination is matched), the first variable winning device operating condition determining means 58 for determining the condition for converting the first variable winning device 7 to the second state. Is constituted by the gate passing ball number counting means 54 and the ordinary electric accessory opening passing ball number judging means 56. In addition, when the normal electric auditors product opening passing ball number determining unit 56 determines that the comparison determination memory number and the gate passing ball number match, the normal electric auditors object opening passing ball number determining unit 56 determines the gate passing ball number counting unit. By sending a reset signal to 54, the count value of the gate passing ball number counting means 54 is reduced to zero, and from this time point, the first variable winning device operating condition determining means 58 newly passes the gate passing ball detector 26 through the gate. The sphere detection signal is counted.

Further, when the ordinary electric auditors product drive control means 57 converts the first variable winning device 7 into the second state, it sends an opening signal to the ordinary electric prizes opening display control means 59, and the ordinary electric prize winning device 7 is displayed. The accessory release display control means 59 emits a normal electric accessory release display 60 such as an LED to visually display to the player. A timer 61 is provided as a time measuring means for measuring the opening time of the first variable winning device 7 by the ordinary electric auditors product drive control means 57, and for example, the ordinary electric auditors object open passage number determining means 56. When the drive control command is further received, the time counting cycle of the predetermined time counted by the timer 61 is counted, and the timing for closing the first variable winning device 7 is determined depending on how many time counting cycles of the timer 61 have elapsed. You may do so. Alternatively, the driving control command is also sent from the ordinary electric accessory opening number determining means 56 to the timer 61 (indicated by a broken line in FIG. 10), and the driving command signal is received to cause the timer to operate. 61 starts the clocking of a predetermined time set in advance, and when the timer 61 clocks the predetermined time, based on the opening end command signal sent to the ordinary electric auditors product drive control means 57 by the timer 61, the ordinary electric auditors product drive control means 57 may reconvert the first variable winning device 7 into a first state that is disadvantageous to the player.

As described above, when the first variable prize device 7 is converted into the second state which is advantageous to the player, the probability of winning the first variable prize device 7 is increased, and the first variable prize device 7 is won. Winning balls are relatively easy to generate. Then, the sphere that has won the first variable winning device 7 is detected as a specific winning sphere by the special symbol starting winning detector 30, and based on the fact that the specific winning sphere can be detected, a prize sphere ejected (not shown) is discharged. By the operation of the operation control unit, a predetermined number (eg, 7) of prize balls are discharged from the prize ball discharging device 17.

The base value comparison / determination means 53 described above is used.
When the award ball number determining means 62 determines that the discharged award ball number should be adjusted based on the determination result of, the award ball number determining means 62 discharges according to the determination result of the base value comparison determination means 53. The number of prize balls is supplied to the ball discharge device drive control means 63.
Then, the ball ejection device drive control means 63, which has received the number of discharged prize balls from the prize ball number determination means 62, invalidates the discharged prize ball number instructed by the prize ball discharge operation control section, and is determined by the prize ball number determination means 62. The number of prize balls corresponding to the number of supplied discharge prize balls is discharged from the ball discharging device 17. In this way, when the prize balls are discharged from the ball discharging device 17, the discharge ball number signal corresponding to the number of discharged prize balls is supplied from the prize ball discharging device 17 to the base value calculating means 52, and a new base value is obtained. It is calculated.

When the number of discharged prize balls is set to be smaller than the preset number of discharged prize balls by the control of the prize ball number determining means 62 as described above, the first variable winning device 7 is hit. The game profit received by the player when a prize is won is reduced, and the base value as the normal return rate calculated by the base value calculation means 52 becomes low.

On the other hand, when the number of discharged prize balls is changed to be larger than the preset number of discharged prize balls by the control of the prize ball number determination means 62, the hit ball is won in the first variable winning device 7. The game profit received by the player at that time increases, and the base value as the normal return rate calculated by the base value calculation means 52 increases.

Therefore, when the base value comparison / determination means 53 determines that the actual base value is higher than the preset base value, the prize ball number determination means 62 is preset in the prize ball discharge operation control section. By selecting the number of discharged prize balls less than the number of prize balls and supplying the number of discharged prize balls to the discharge device drive control means 63, the base value calculated thereafter can be lowered. Similarly, when the base value comparison determination unit 53 determines that the actual base value is lower than the preset base value, the prize ball number determination unit 62 causes the prize ball discharge operation control unit to preset the prize ball. It is possible to increase the base value calculated thereafter by selecting the number of discharge prize balls larger than the number and supplying the number of discharge prize balls to the discharge device drive control means 63. That is, the prize ball number determination means 62 functions as a normal return rate correction means that brings the base value as the normal return rate to the player close to the set value.

The forced change control of the number of discharged award balls by the award ball number determining means 62 is performed by the base value comparison / determination means 5.
Each time the judgment result from 3 is received (in other words, every time the effective firing ball number calculating means 51 calculates the effective firing ball number and the base value calculating means 52 calculates the current base value), the prize ball discharging device is driven. Instead of supplying a new number of discharged prize balls to the control unit 63, the forced control activation unit 64 including the base value calculation unit 52, the base value comparison determination unit 53, and the prize ball number determination unit 62 outputs the determination result. Forced when the specified number of times is reached (when the number of samplings reaches the specified number), or when the absolute value of the difference between the set reference base value and the actual current base value exceeds the specified range. You may make it control dynamically.

Further, when the determination result of the base value comparison / determination means 53 indicates that forced control is required, the award ball number determining means 62 sets the newly set award number of discharged award balls to the ball discharge device drive control means 63. The number of newly ejected prize balls is not limited to that which is continuously supplied to the prize ball ejector drive control means 6
3, the number of discharged prize balls of the ball discharge device drive control means 63 is fixed to a new numerical value, and the number of discharged prize balls from the prize ball discharge operation control unit is influenced in the discharge operation performed thereafter. Alternatively, when the discharge operation command is received from the prize ball discharge operation control unit, the discharge operation for the number of prize balls determined by the prize ball number determination means 62 may be performed. in this case,
The number of prize balls fixed to the ball discharge device drive control means 63 may be released after continuing the prize ball discharge operation based on the changed number of prize balls up to a predetermined number of times. Until the determination means 62 supplies another number of discharged prize balls, or until the prize ball number determination means 62 sends a prize ball number change cancel command based on the determination result from the base value comparison determination means 53. You can In addition, the ball discharge device 1
When 7 is configured to be capable of discharging independently,
It is not necessary to provide the ball discharging device drive control means 63, and the number of prize balls discharged by the ball discharging device 17 is changed to the newly set discharge prize ball number by the prize ball number determining means 62.
A control means for sending a prize ball number changing command to the ball discharging device 17 may be provided in the electric control device 23.

Furthermore, the number of prize balls determining means 62 changes the number of discharged prize balls not only for the number of prize balls for a specific prize ball to the first variable prize device 7, but for any prize ball. Also, the number of discharged prize balls may be controlled. In such a case, it is not necessary to separately provide a prize ball discharge operation control unit, and the prize ball number determination means 62 may be configured to constantly manage the discharged prize ball number.

When the first variable winning device 7 is converted into the second state, the hit ball that has flowed down easily enters the first variable winning device 7, and when the hit ball actually wins, this hit ball is a specific winning signal generating means. The special symbol start winning a prize detector 30 as is detected and sends the specific winning signal to the ordinary electric auditors product drive control means 57 and the starting memory control means 66 of the electric control device 23.
Further, the special symbol start winning detector 30 also sends the specific winning signal to the base value calculating means 52, and the base value calculating means 52 calculates the base value at the timing when the external signal is input. good.

When the normal electric auditors product drive control means 57 receives the specific winning signal from the special symbol starting winning award detector 30, even before the timer 61 measures a predetermined time, the solenoid of the first variable winning device 7 Is demagnetized, and the first variable winning device 7 is returned from the second state where the hit ball is easy to win to the first state where the hit ball is hard to win. In addition, the first variable winning device 7 is the first
Even if the ball returns to the state, there is a possibility of winning the ball, and even when the ball hits the first variable winning device 7 in the first state, the special symbol starting prize detector 30 is the winning ball as in the case of the winning. Is detected and a specific winning signal is transmitted.

When the starting memory control means 66 receives a specific winning signal from the special symbol starting winning detector 30, the special winning signal is stored and the special symbol display device is started in the starting memory display controlling means 66 based on this memory. The right signal is sent, and the start memory display control means 66 causes the start memory indicator 67 composed of an LED or the like to emit light so that the player can visually display the number of memories of the special symbol display device start right. Therefore, when the hit balls successively win the first variable winning device 7, the starting memory control means 66 stores the specific winning signals one after another, and the number of memories is visually displayed on the starting memory display 67.

Further, when the starting memory control means 66 receives and stores the specific winning signal from the special symbol starting winning award detector 30, the signal is sent to the special symbol display device display controlling means 68 and the random number extracting means 69 based on this memory. .

When the special symbol display device display control means 68 receives a signal from the starting memory control means 66, the operation of the special symbol display device 6 is started based on this signal, and the numbers can be changed on the three display devices 31a to 31c. indicate.

The random number extracting means 69 is the starting memory control means 6
When the signal is received from 6, the random number is picked up from the random number table set by the set random number selecting means 70 and sent to the big hit judging means 71, and the big hit judging means 71 judges whether or not the random number corresponds to the big hit. If it is a "big hit", a special game (detailed later) for converting the second variable winning device 9 from the first state, which is disadvantageous to the player, to the second state, which is advantageous to the player, is started. .. That is, the starting memory control means 66 for storing the starting winning ball detection signal from the special symbol starting winning award detector 30, the random number extracting means 69 for taking out a random number based on the starting memory of the starting memory control means 66, the random number being a big hit. The jackpot determination means 71 for determining whether or not they correspond to each other function as the second variable winning device operating condition forming means 72 for forming the operating condition of the second variable winning device 9.

In the present embodiment, the probability of winning the prize mode in another game performed using the special symbol display device 6 can be preset to, for example, 6 levels, 6
There is provided a random number table of a kind (detailed later), and by performing another game based on the set random number table, the second variable winning device 9 is converted into a second state advantageous to the player. The probability of the special game being played is adjustable.

In the case of setting the probability that a special jackpot mode is formed on the special symbol display device 6, first, the setting operation unit 1
Insert the key into the key hole of 9. When the key is inserted, the key insertion detector 73 detects the insertion of the key and sends an activation signal to the special symbol probability setting storage control means 74 and the setting display control means 75, and the special symbol probability setting storage control means. While making 74 a state in which the signal from the special symbol probability setting switch 76 can be effectively received, the setting display control means 75 operates to start displaying on the setting display 77 which is a 7-segment display.

By operating the special symbol probability setting switch 76 by the administrator, the special symbol probability setting storage control means 74
When the signal is sent to, the special symbol probability setting storage control means 74 which receives this signal sends a signal to the setting random number selecting means 70 and also sends a signal to the setting display control means 75. The special symbol probability setting switch 76 may be turned on / off by rotating the key, or may be configured by a dial type switch provided separately from the key.

Upon receiving the signal from the special symbol probability setting storage control means 74, the set random number selecting means 70 is special in accordance with the signal from the special symbol display device random numbers 1 to 6 stored in advance for each probability. Select one random number for symbol display device. These special symbol display device random numbers is a random number table in which the probability of winning (forming a prize mode) is changed stepwise, for example, the special symbol display device random number 1 is 1/15.
0, special symbol display device random number 2 1/200, special symbol display device random number 3 1/220, special symbol display device random number 4 1/250, special symbol display device random number 5 1/3
00, the special symbol display device random number 6 is adjusted to a probability of 1/350. Therefore, for example, when the dial type special symbol probability setting switch 76 is set to "1", the set random number selecting means 70 selects the random number 1 for the special symbol display device with the probability 1/150, and the setting display 77 in accordance therewith. To "1"
Is displayed, and when the special symbol probability setting switch 76 is set to "2", the set random number selecting means 70 selects the special symbol display device random number 2 with a probability of 1/200, and the setting indicator 77 is accordingly displayed. “2” is displayed, and so on, by operating the special symbol probability setting switch 76, it is possible to freely select any random number from among the special symbol display device random numbers prepared in advance, and the selected random number Types are displayed visually on the setting display 77.

When a random number with a desired probability (for example, a random number 2 for special symbol display device with probability 1/200) is selected and operated according to the business policy, the key is pulled out, whereby the selected random number is fixed. Thus, the business of the day can be performed in this state. That is, while storing the occurrence probability of the special symbol set through the special symbol probability setting switch 76, special symbol probability setting control means for controlling the set random number selecting means 70 so as to select a random number according to the occurrence probability 73, the special symbol probability setting control means 73
Based on the operation control of the special symbol display device random numbers 1 to 6 set random number selection means 70 for selecting a random number table according to the occurrence probability of the special symbol, special symbol display device random number 1 set to a predetermined probability 6 to 6 constitute the special game right generation condition formation rate setting means 78 for setting the prize mode formation rate of the special symbol display device 6 which is the right generation condition for the special game by mutually functioning.

After setting in this way, when the random number extracting means 69 receives a signal from the starting memory controlling means 66, the random number for the special symbol display device with the probability 1/200 selected by the setting random number selecting means 70 is thereby generated. One random number is picked up from 2 and sent to the jackpot judging means 71 for judgment.

When the big hit determination means 71 determines that "there is no", that is, the prize mode is not formed, a signal is sent to the stop symbol selection means 79, and the stop symbol selection means 79 is removed from the removal symbol generation means 80 (for example, a symbol). , "3, 1, 5"), so that the variable display of the special symbol display device 6 is stopped with this symbol, a signal is sent to the special symbol display device display control means 68, and thereby the special symbol display device. The display control means 68 changes the variable display of the special symbol display device 6 to "3, 1, 5".
Stop at.

On the other hand, when the big hit judging means 71 judges that a "hit", that is, a prize mode is to be formed, a big hit signal is sent to the big hit control means 81, and a signal is sent to the stop symbol selecting means 79 to stop it. The symbol selecting means 79 is a winning symbol from the winning symbol generating means 82 (for example, "7, 7,
7 ”) is selected and a signal is sent to the special symbol display device display control means 68 so that the variable display is stopped in this symbol, whereby the special symbol display device display control means 68 causes the special symbol display device 6 to variably display. Stop at "7, 7, 7".

When the big hit control means 81 receives the big hit signal, it sends a signal to the base value calculation means 52 to temporarily stop the calculation of the base value until the special game ends. As a result, the number of effective shot balls and the number of discharged prize balls during the special game are invalidated, and the significance of calculating the base value can be maintained.

During the special game started as described above, the base value calculation means 52 does not calculate the current base value, so the prize ball number determination means 62 also temporarily stops its operation and the prize ball discharge operation control. Based on the control of the unit, the ball ejection device drive control means 63 causes the ball ejection device 17 to eject a predetermined number of prize balls. The number of prize balls determination means 6
If 2 is configured to determine all prize balls,
For example, while the jackpot control means 81 is performing special game control, a signal is output to the award ball number determining means 62, and while the signal is being input, a normal award by the award ball number determining means 62 is performed. The ball discharging operation may be performed on the ball discharging device drive control means 63.

Further, when the big hit control means 81 receives the big hit signal, it sends a signal to the big winning opening drive control means 83, and based on this signal, the big winning opening drive control means 83 causes the door member of the second variable winning device 9. By energizing the solenoid as the driving means, the first state in which the hit ball is not accepted is converted to the second state in which the hit ball is easily accepted and the special game of the first cycle is started. When the jackpot control means 81 receives the jackpot signal, the cycle number indicator 84 visually displays the cycle number, for example, "1".

In the first cycle of the special game, when the gaming balls win the second variable winning device 9, the counting detector 41 detects one of these winning balls, and the special winning opening drive control means 83 and the big hit. A signal is sent to the control means 81, and the big hit control means 81 counts the number of winning balls in the cycle based on this signal and visually displays it on the winning number display 85. In the first cycle, the number of winnings to the second variable winning device reaches a predetermined number (for example, 10) or a predetermined time (for example, 2) set in a timer in the big hit control means 81.
If the hit ball does not enter the continuous winning opening 39 before the elapse of (8 seconds), the jackpot control means 81 ends the special game based on the satisfaction of either one of the ending conditions, but these When the hit ball wins the continuous winning opening 39 before the end condition is satisfied, the continuation detector 42 detects the winning ball in the continuous winning opening 39 and outputs a continuation signal to the special winning opening drive control means 83 and the big hit control means 81. send. Then, the jackpot control means 81 that has received this continuation signal causes the continuation indicator 86.
By activating (lighting, blinking, etc.), the player is visually displayed that the continuation condition is satisfied. In addition, when the special game ends when the end condition is satisfied without the hitting of the ball in the continuous winning opening 39, the jackpot control means 81 sends a signal to the base value calculation means 52 to restart the calculation of the base value. Return to the playing state.

On the other hand, when the continuation condition is satisfied by the ball hitting the continuous winning opening 39, the special winning opening drive control means 83 temporarily demagnetizes the solenoid of the second variable winning device 9 to return it to the first state, and the predetermined condition is reached. After the lapse of the wait time, the solenoid of the second variable winning device 9 is excited again to be converted into the second state. Further, the jackpot control means 81 resets the winning number display 85 to zero, stops the operation of the continuous display 86, updates the display of the cycle number display 84, and visually displays, for example, "2".

In this way, by hitting the ball into the continuous winning opening 39, the cycle is updated and the special game is continued, and the update of the cycle is repeated a predetermined number of times (for example, 16 times).
When the number of winnings reaches a predetermined number in the final cycle or a predetermined time elapses, the special game ends when the number of times reaches). When the special game ends, the base value calculation means 52 starts to operate by a signal from the big hit control means 81 and returns to the normal game state, as in the case where the special game ends.

As described above, in the present embodiment, the base value serving as the reference is set in advance, the base value in the actual game is calculated, and both base values are compared, and the actual base value is more than the reference base value. When the base value in the game is low, the award ball number determining means 62 sets a discharge award ball number that is larger than the preset award ball number, and increases the award ball number as a profit for the player. Thus, control is performed so that the actual base value rises and approaches the reference base value. On the other hand, when the base value in the actual game is higher than the reference base value, the prize ball number determining means 62 sets a prize ball number smaller than the preset prize ball number, and the player receives a profit. The number of prize balls is reduced so that the actual base value gradually decreases and approaches the reference base value.

That is, the prize ball number determination means 62 as the normal return rate correction means intervenes in the control of the ball discharge device drive control means 63 for controlling the prize ball discharge operation by the ball discharge device 17, so that the player Therefore, it becomes possible to bring the base value indicating the normal reduction rate into the reference standard value set in advance. Therefore, even if the obstacle nail (particularly, the life nail that normally affects the winning probability to the first variable winning device 7) is not adjusted, the base value obtained as the actual business result approaches the pre-scheduled base value, Can be stabilized. Then, the special game right generation condition formation rate setting means 7
Since the prize mode formation probability of the special symbol display device 6 can be set to a desired probability via 8, the gaming machine 1 can be set by this setting.
Individuality can be created for each, and the payout rate and the divisor can be adjusted with this.

It should be noted that the base value as a reference can be freely set to a desired value in accordance with the business policy for each gaming machine 1, or the base value prepared stepwise can be selected and set. Good. For example, when the base value to be the reference is selected and set from the prepared base values, the base value varying means is operated via the key insertion detector or the like, similarly to the operation of the special symbol probability setting switch 76 described above. 87 is activated. As a result, when the base value changing means 87 including the base value setting storage control means and the base value setting display control means is activated, it becomes possible to effectively receive the signal from the base value setting switch 88. For example, the base value setting display control means is operated so that the reference base value is visually displayed on the base value setting display 89, which is, for example, a 2-digit 7-segment display.

Then, the administrator sets the base value setting switch 8
For example, when any of the six reference base values is sent to the base value setting storage control means in the base value changing means 87 by operating 8, the base value setting is received. The storage control means sends a signal to the reference base value selection means and also sends a signal to the base value setting display control means.

Upon receipt of the reference base value selection signal, the reference base value selecting means stores the previously stored base value 1
1 to 6, one base value corresponding to the above signal is selected. For example, the base value 1 is “3
5 ", base value 2 is" 45 ", base value 3 is" 50 ",
The base value 4 is "55", the base value 5 is "60", and the base value 6 is "70". Therefore, for example, when the display of the base value setting indicator 89 is set to "1" by the base value setting switch 88, the reference base value selecting means is changed to "3".
Select the standard base value 1 of "5" and set the base value display 8
9 is displayed so that "3" is displayed, the reference base value selection means selects the reference base value 3 of "50", ..., And the reference prepared in advance by the operation of the base value setting switch 88. Any base value can be selected from the base values, and the selected base value is visually displayed on the base setting display. Then, when a desired base value (for example, “45”) is selected and the key is pulled out, this base value is set as a reference base value for business on that day, and this reference base value is set in the base value comparison / determination means 53. Sent. Therefore, the base value comparison determination means 53 compares the reference base value with the base value in the actual game.

For example, when the base value 2 is selected and the business is started, when the hitting ball launching device 11 shoots hit balls one after another, the number of effective shot balls is calculated based on signals from the launch ball sensor 22 and the foul ball sensor 25. The means 51 calculates the number of effective shot balls, the base value calculation means 52 calculates the current base value based on the calculation result, and the calculated current base value and the reference base value in the base value changing means 87 are selected. The base value comparison / determination means 53 compares the setting reference base value from the means. Then, the set reference base value “4
5 ”, the base value from the base value calculating means 52 is less than“ 45 ”, the base value comparing and judging means 53.
However, it is determined that the base value of the actual game is low,
A signal to that effect is sent to the prize ball number determining means 62.

Thus, the prize sphere number determining means 62 sets the number of discharged prize spheres larger than the preset reference prize sphere number based on the signal from the base value comparison and determination means 53. It should be noted that the number of discharged prize balls set by the number of prize balls determination unit 62 is set to the ball discharge device drive control unit 6 when the forced change is performed.
3 may be sequentially added to the number of discharged prize balls by "1", or in advance according to the difference between the reference base value and the current base value in the judgment result of the base value comparison and judgment means 53. A new number of discharged prize balls may be set by adding the set number of balls to the reference prize ball number.

When the current base value is lower than the reference base value, the award ball number determining means 62 forcibly changes the award ball number to a number smaller than the reference award ball number, and as a profit to be obtained by the player. The number of discharged prize balls has increased, and the base value calculation means 5 has received a signal from the ball discharge device 17 to arrive at the number of discharged prize balls.
2 adds the increased number of prize balls to calculate the base value again, so that the current base value is substantially increased.

On the other hand, when the base value from the base value calculation means 52 exceeds "45" with respect to the set reference base value "45", the base value comparison / determination means 53 causes the base value of the actual game. Is determined to be high, and a signal to that effect is sent to the award ball number determination means 62. Also in this case, similarly to the above, the prize ball number determining means 62 sets a new discharge prize ball number and the ball discharge device drive control means 63 forces the discharge prize ball number to exceed the reference prize ball number. Also reduce.

If the current base value is higher than the reference base value, the number of discharged prize balls by the ball discharge device drive control means 63 is changed to a number smaller than the reference prize ball number. The number of discharged prize balls as a profit to be obtained decreases, and the base value calculation means 52 which receives a signal from the ball discharging device 17 to arrive at the number of discharged prize balls adds the reduced number of prize balls to obtain the base value again. As it is calculated, the current base value drops substantially.

Further, when the absolute value of the determination result of the base value comparison / determination means 53 becomes a predetermined value, the prize ball number determination means 62 may be effectively operated. For example, a reference base value (a preset reference base value or a difference between the reference base value selected by the reference base value selection means and the current base value calculated by the base value calculation means 52 is a predetermined value (for example, 0.5)). The award ball number determining means 62 may be operated only when the number exceeds the value, that is, with respect to the base value “45” from the reference base value selecting means,
When the base value from the base value calculation means 52 is "44.5" or less, or "45.5" or more (the absolute value of the difference between the reference base value and the current base value exceeds "0.5". In this case, the base value comparison / determination means 53 causes the prize ball number determination means 6 to
It is also possible to send a determination signal to No. 2 and the prize ball number determination means 62 forcibly changes the memory number for comparison determination in the normal electric auditors product open passage ball number determination means 56 based on this signal.

In the gaming machine 1 described above, the combination of the base value selected by the reference base value selection means and the special symbol display device random number selected by the probability setting random number selection means 70 is 6 × 6 = 36 ways. Yes, this combination can be selected appropriately.

In this case, if a random number with a high probability is selected as the random number for the special symbol display device (for example, a random number 1 for the special symbol display device with a probability of 1/150), the probability that the right to the special game is generated becomes high. The number of balls discharged significantly increases within a short period of time, and the payout rate (divided rate) becomes high. In other words, the profit earned by the player side in a short time increases rapidly and the profit earned by the game store side sharply increases. It becomes a state that becomes small, on the contrary, a random number with a low probability (for example, probability 1
If you select the random number 6/350 for the special symbol display device, the probability that the right to the special game will be generated will be extremely low, and the number of prize balls discharged will increase significantly within a short period of time, and the winning rate (divided number)
Is almost never sharply increased, in other words, there is almost no situation in which the profit earned by the player in a short time is rapidly increased and the profit earned by the game store is drastically reduced.

If a high base value (for example, base value "70") is selected as the reference base value, even if no special game is played, if 100 balls are shot on average, 70 prize balls will be obtained. Since the game can be played at the rate of being discharged, it becomes a state where the game can be continued for a relatively long time (a state where the ball is in good condition), and on the contrary, a low base value (for example, a base value) to the reference base value. If you select "35"), you can play the game at a rate that 35 prize balls are discharged if you shoot 100 balls on average, so the game ends in a relatively short time ( The ball is in a bad state). Therefore, it is necessary to select the random number for the special symbol display device of each gaming machine and the reference base value according to the business policy.

For example, when a new store is opened, the standard base value is increased to improve the ball elasticity, and the probability of the special symbol display device random number is increased so that the right to the special game is easily generated. If you set based on a business policy that allows you to play, you can raise the reference base value to lower the probability of random numbers for special symbol display devices or set to a medium level, and compete in a short time In order to make it a gaming machine, the standard base value is set low and the probability of the random numbers for special symbol display devices is set high, with the goal of unilaterally gaining profits at the amusement store side by exhausting the game balls within a short time. In order to do so, the standard base value is set low and the probability of the special symbol display device random number is also set low.

As described above, the random number for the special symbol display device of each gaming machine and the reference base value may be set by separate operations according to the business policy, but a plurality of combinations (sales mode) are preset. However, if this business mode is selected, the special symbol display device random number and the reference base value may be automatically set.

For example, the electric control device 23 is provided with a mode setting storage control means, a mode setting display control means, etc., and a plurality of types of combinations of special symbol display device random numbers and reference base values are predetermined in the mode setting storage control means. Keep it. For example, the random number 1 (probability 1/150) for the special symbol display device and the reference base value 6 in the "opening mode", which is also called "mode 1"
The combination with "70" of "mode 2" is also called "play mode 1" and the random number 5 for special symbol display device (probability 1/3)
00) and the standard base value 5, "60",
A combination of a random number 4 for special symbol display device (probability 1/250) and a reference base value 4 of "55" is referred to as "game mode 1", which is also referred to as "mode 3". Is a special symbol display device random number 1 (probability 1/15
0) and the reference base value 1 of "35" are combined, the "mode 5" is also called "winning mode 2", and the special symbol display device random number 2 (probability 1/200) and the reference base value 2 of "4".
The combination with "5", the random number 6 for special symbol display device (probability 1/350) in "collection mode", which is also called "mode 6"
And the reference base value 1 of “35” are set in advance.

In the case where the mode is set as described above, when the administrator performs the mode setting operation, the key insertion detector detects the insertion of the key by inserting the key into the keyhole. Then, an activation signal is sent to the mode setting storage control means and the mode setting display control means to activate both of these control means, and when the business mode setting switch is operated, "mode 1" to Any one of the “mode 6” business modes can be selected. Then, when one business mode (for example, "mode 2") is selected by the mode setting storage control means, a signal indicating the business mode is sent to the mode setting display control means, the set random number selection means, and the reference base value selection means. Sent.

When the mode setting display control means receives a signal from the mode setting storage control means, the business mode, for example, "mode 2" is visually displayed on the mode setting display. Therefore, the administrator can surely perform the work of setting the business mode while checking the display of the mode setting display.

When the probability setting random number selecting means receives a signal from the mode setting storing control means, it selects the special symbol display device random number corresponding to the signal. For example, when "mode 2" is set, the special symbol display device random number 5 (probability 1/30)
Select 0).

Further, when the reference base value selecting means receives the signal from the mode setting storage control means, it selects the reference base value according to the signal. For example, when “mode 2” is set, “60” of the reference base value 5 is selected and this reference base value is sent to the base value comparison / determination means 53.

Therefore, when the business is started in this business mode, the base value comparison / determination means 53 causes the base value "6".
"0" as a reference is compared with the current base value to forcibly adjust the outcome of the normal symbol display device, the first variable winning device 7 is won, and a specific winning signal is sent to display a special symbol. The result of the variable display on the device is controlled by the special symbol display device random number 5 with a probability of 1/300.

In each of the above-mentioned embodiments, when the current base value is calculated by the base value calculating means 52, the total number of prize balls discharged from the ball discharging device 17 and the effective firing balls from the effective firing ball number calculating means 51. I calculated the ratio with the number,
The calculation of the base value in the present invention is not limited to this.

For example, a ball detector 44 is also provided in each of the general winning openings 43 through which the winning balls are discharged when a hit ball wins, or the winning balls that entered the winning openings 43 flow down into the flow path. A detector 44 is provided, and based on a signal from the detector 44, the number of prize balls discharged by a general prize in the normal gaming state is calculated from the number of prize balls determined for each winning opening 43. In addition, the number of award balls acquired by the player may be obtained as a game profit by adding the number of award balls discharged for the specific prize set and changed by the award ball number determining means 62. In this way, if the game profit is calculated only from each game data of the gaming machine 1 without using the number of prize balls discharged from the ball discharging device 17, the ball discharging device 17 is also used for ball rental. Even in the gaming machine 1 configured to do so, it is not necessary to distinguish between the prize ball discharge signal and the ball rental discharge signal, and there is no influence on the structure of the ball discharge device 17.

In addition, when the obstacle nail is arranged or adjusted so that the hit ball hardly wins in the general winning opening,
Since the number of prize balls discharged by winning the first variable winning device can be used as a basis for calculating the base value, a change in the number of prize balls discharged can be promptly reflected in the base value control. In such a case, most of the winnings in the first variable winning device 7 and extremely few winnings in the general winning opening 43 are detected. Therefore, only the winning balls in the first winning device 7 are detected, Even if the base value is calculated by using the number of discharged prize balls based on the winning of the first variable winning device 7 as the game profit, it is possible to achieve the purpose without any trouble.

Further, when calculating the base value, the effective denominator is used as the denominator (the number that becomes the base of the base value) as the number that is disadvantageous to the player required for the game, but this is the denominator. The number is not limited to this, and the number of effective shots is not limited to that detected by the shot ball sensor 22 and the foul ball sensor 25 and the number of effective shots is calculated based on the signals from these sensors. For example, an out-ball detector that detects one out-ball (a ball that has not won any prize) won from the gaming machine 1 and a safe ball (a ball that wins any prize) It is also possible to provide a safe sphere detector for detecting one of the two and to calculate the number of effective launch balls by the sum of the signals from both detectors as the collected sphere detecting means.

Further, in the above embodiment, the gate passing ball detector 26 is used as the specific game data collecting means, and the specific game data related to the player playing the game is set as the number of gate passing balls. The game data of is not limited to the number of passing winning balls of the winning gates 8 and 8.
For example, a specific area provided in the game section 5 of the game board 3 is set as a windmill or a general winning hole 43, and the windmill rotates when a hit ball passes, or a ball detector in the winning hole 43. You may comprise so that a data signal may be sent to the 1st fluctuation | variation winning device operation condition determination means 58 whenever 44 detects a winning ball. Then, this data signal is counted as the number of balls passing through the specific area in the first variable winning device operation condition determining means 58, and based on whether or not the number of balls passing through the specific area reaches a predetermined number, The condition for converting the first variable winning device 7 to the second state may be determined by the first variable winning device operating condition forming means 58. Furthermore, the number of passing balls in the specific area which is a condition for opening the first variable winning device 7 is not limited to a fixed number, and a passing ball number changing means 90 whose setting can be changed by, for example, an external operation is provided, and if necessary. Alternatively, the opening probability of the first variable winning device 7 may be adjusted.

In the present embodiment, when the ball flowing down in the game section 5 wins the winning gates 8, 8 functioning as the first specific winning opening, the winning ball in the first specific winning area is detected. The normal symbol start winning switch 92 as the first specific winning signal generating means for generating the first specific winning signal detects this sphere and sends a signal to the electric control device 23, which passes through the winning gate 8. And flows down in the game section 5 again. Therefore, prize balls are not discharged. Further, in the present embodiment, the first specific winning signal transmitted from the normal symbol starting winning switch 92 of the winning gate 8 becomes a starting condition establishment signal of the normal symbol display device 91 described later. The winning gate 8 may have any structure as long as it can send a signal by detecting a hit ball by the normal symbol starting prize switch 92, and is not limited to the structure or the mounting position of the normal symbol starting prize switch 92, and the detected hit ball is detected. May be taken in as a prize ball and discharged as a prize ball.

Under normal control of the electrical control device 23, the normal symbol display device 91 converts and displays symbols (numerals) such as symbols and numbers at a speed that cannot be visually identified, and the symbols when the conversion display is stopped are displayed. If the stop display mode is a preset mode, the privilege is given to the player. The normal symbol display device 91 shown in the drawing is composed of a 7-segment display, and when the signal from the electric control device 23 is used for high-speed conversion display of the numbers "0" to "9", the variable display is stopped. If the number displayed on the screen is a preset number, for example, “7”, it means that the prize mode has been formed, and as a privilege, the condition for converting the first variable prize device 7 into a state advantageous to the player is established. Let That is, the normal symbol display device 91 in the present embodiment determines the formation of the operating condition of the first variable winning device 7 by the first specific winning signal from the first specific winning signal generating means (normal symbol starting winning switch 92). It functions as a part of the first variable winning device operating condition forming means 58 '.

Further, the probability that the prize mode is formed on the normal symbol display device 91 is adjusted by comparing a preset reference base value with the current base value calculated in the actual game, as will be described later. The winning probability to the first variable winning device 7 is adjusted by, and as a result, the current base value in the actual game approaches the set base value. In addition, the normal symbol display device 91 not only variably displays the symbols, but also sequentially blinks a plurality of lamps to form a prize mode when the blinking movement is stopped by a predetermined lamp and continuously lit. You may comprise.

Next, with regard to the gaming machine 1 provided with the above-mentioned ordinary symbol display device 91, the contents of the game different from the above embodiment will be described.

The control means 59 turns on or blinks the normal electric accessory opening display 60 such as an LED to visually display to the player that the first variable winning device 7 as the normal electric accessory is in the open state.

Here, in the present embodiment, nail adjustment is performed so that the ball can be easily guided to the first variable prize device 7, and the inside of the first variable prize device 7 is used as the second specific prize area. Based on the special symbol start prize detector 30 detecting the second specific prize ball which is the prize ball to the first variable prize device 7, the special symbol start prize detection signal which is the second specific prize signal. When the second variable winning device operating condition forming means 72 is supplied, the second variable winning device operating condition forming means 72 makes the second change based on the second specific winning signal.
A second variable winning device operating condition forming process is performed to determine whether or not the variable winning device 9 is converted to the second state. Then, when the second variable winning device operation condition is formed, the special game similar to the above-described embodiment is started.

On the other hand, based on the fact that the hit ball is won in the first variable winning device 7, the special symbol starting winning detector 30 is supplied with a special symbol starting winning detecting signal to the base value calculating means 52. Yes, the base value calculation means 52
The number of prize balls corresponding to the winning mode supplied from the winning symbol selecting means 96 is discharged, and based on the special symbol starting winning detection signal and the winning symbol, the game profit received by the player (for example, The cumulative value of the number of prize balls acquired by the player) is calculated. Next, the base value calculation means 52 calculates a base value from the above-mentioned game profit and the number of effective firing balls supplied from the number of effective firing balls calculation means 51, and supplies the calculation result to the base value comparison determination means 53. Furthermore, the base value calculation means 5 that has received the new special symbol start winning detection signal
2 again calculates the base value in the same manner as above.

As described above, the base value calculating means 52
The base value comparison / determination means 53 to which the newer current base value is supplied is based on the new current base value being supplied from the base value computing means 52, and the current base value and the preset reference base value. Is compared, and the result of this comparison and determination is supplied to the symbol selection means 96. Further, when the new current base value is supplied from the base value calculation means 52, the base value comparison determination means 53 supplies the comparison result to the hit symbol selection means 96 again in the same manner as above.

Thus, when the judgment result is supplied from the base value comparison and judgment means 53, the winning symbol selection means 96 is the first
As the ball hitting the variable winning apparatus 7, the prize ball number signal corresponding to the winning symbol supplied to the normal symbol display control means 93 is supplied to the prize ball number control means 97, and the prize according to the prize ball number signal. The prize ball number change control means 97 outputs to the ball discharge device 17 a prize ball number change command signal according to the discharged prize ball number so that the ball discharge is performed by the ball discharge device 17.

Here, the ball discharging device 17 shown in the present embodiment.
Has a function of discharging a game ball as a prize ball based on a game result and a ball rental discharge function based on a player requesting a ball rental using a currency or a prepaid card. The control device 23 is provided with a prize ball discharging operation control means independent from the control device 23, and when a winning hole other than the first variable winning device 7 is won, the electric control device 2 is operated.
Based on the prize ball discharge signal input from the prize ball discharge controller 3 (not shown), a predetermined number of prize ball discharge operations are performed. However, when an award ball number change command is input from the award ball number change control means 97, the number of award balls to be changed is ejected in preference to the preset number of award balls to be ejected. The device 17 operates. When the ball discharging device 17 has the same configuration as that of the above-described embodiment, a drive control portion such as a ball discharging device operation control means may be appropriately provided in the electric control device 23.

Also, the winning symbol selecting means 96 which has received the determination result from the base value comparing / determining means 53 selects the winning symbol again, and prepares when the winning symbol is supplied from the normal symbol hitting determining means 95. And from the judgment result of the first variable winning device operating condition judging means 58 'based on the fact that the normal symbol starting winning prize detection signal is inputted from the normal symbol starting winning prize switch 92, the normal symbol hit judging means 95 makes a hit judgment. In this case, similarly to the above, the normal electric auditors product opening drive control means 57 converts the first variable winning device 7 into the second state, and the prize balls are discharged based on the winning of the first variable winning device 7. The prize ball number change control means 97 causes the ball discharging device 17 to perform the operation. As described above, even after the hit symbol selection means 96 selects a new hit symbol, if a new comparison determination result is input from the base value comparison determination means 53, the normal symbol display control means 93 The winning ball number signal based on the winning symbol supplied to the winning symbol number changing control means 97 is supplied, and a new winning symbol is selected based on the comparison determination result from the base value comparing and determining means 53, and a new winning symbol is selected. Update the design again.

Therefore, when the determination result of the base value comparison / determination means 53 described above requires the base value control (for example, when the current base value and the reference base value do not match, or when the difference between the two base values is detected). When the absolute value exceeds a certain value), the hit symbol selecting means 96 which receives the hit judging signal from the normal symbol hit judging means 95 selects a new hit symbol in the following manner.

When the comparison judgment result from the base value comparison judgment means 53 is within the range where the current base value and the reference base value can be regarded as the same or substantially the same, the winning symbol selecting means 96 It is assumed that “5” is selected as the winning symbol, and the number of prize balls based on the winning of the first variable winning device 7 is 5
