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. There is something that can be adjusted at the amusement store side without making 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 planted on the surface of the game board. By subtly adjusting the angle, interval, etc. of the obstacle nails, the downflow direction of the hit ball is changed to be subtly changed, whereby 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 value in advance, the obstacle nail related to winning must be adjusted according to this 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 enters a game board having a game section having a prize area and a first specific prize area provided on the game board. The first to detect the hit ball and generate the first specific winning signal

A second variable winning device that can be converted into a first state that is unfavorable to the player and a second state that is advantageous to the player, and the second variable winning device by the second specific winning signal from the second specific winning signal generating means. A second variable winning device operating condition forming means for forming operating conditions, a special game right generating condition forming ratio setting means for setting a right generating condition forming ratio of a special game, and a game for detecting a disadvantage required for a player to play a game. Disadvantage detection means,
A normal return rate of profit to the player from the game profit detection means for detecting the profit obtained by the player as a game result, the disadvantage signal from the game disadvantage detection means and the profit signal from the game profit detection means. A normal reduction rate detecting means for obtaining
The normal return rate comparison means for comparing the predetermined normal return rate with the return rate obtained from the game result by the normal return rate detection means, and the comparison result of the normal return rate comparison means to intervene in the control of the game. Normal return rate correction means for bringing the normal return rate to the player closer to the set normal return rate,
It is a game machine characterized by having.

[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. First hit
When entering the specific winning area, the first specific winning signal generating means generates the first specific winning signal, and the first variable winning device operating condition forming means determines the formation of the operating condition based on this signal. In this case, the normal return rate correction means affects the formation of the operating condition by the comparison result of the normal return rate comparison means, and brings the return rate in the actual game closer to the preset normal return rate. Then, when the first variable winning device operation condition forming means determines that the operating condition is satisfied, the first variable winning device converts the first state to the second state, and it is easy for a hit ball to be won. When the player wins the prize, the prize balls are discharged and the player's profit is increased, so that the actual normal return rate is increased. On the other hand, when the first variable winning device operating condition forming means determines that the operating condition is not satisfied, the first variable winning device is not converted into the second state, so that the prize balls are not discharged due to the winning of the first variable winning device, During this time, the game balls are fired to increase the player's disadvantage, and the actual normal return rate decreases.

[0006]

Keys 20a and 20b are provided to prevent these settings from being changed during business hours and to prevent anyone other than a specific administrator from illegally operating them.

The hitting ball launching device 11 may be of any type as long as it has a function of launching the game ball supplied to the launching position formed on the inclined lower end of the launching rail 21.
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 detector 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. The detector 25 is configured to detect a foul ball and send a foul signal to the electric control device 23. In addition, the foul ball detector 25 is
It corrects the data sent as a disadvantage to the player by the firing ball sensor 22, and is not limited to the structure and the mounting position as long as the foul ball can be detected and a foul signal can be transmitted.

A first specific winning opening 8 provided in the game section 5
In this embodiment, in order to satisfy the starting condition of the normal symbol display device 10, is constituted by a gate formed with a ball passage opening through which a hit ball can pass from above,
A detector (normal symbol starting winning switch) 26 that detects a passing ball and sends a signal to the electric control device 23 is provided as a first specific winning signal generating means. Therefore, when the ball flowing down in the game section 5 wins the first specific winning opening 8, the detector 26 detects the ball and the electric control device 23 is detected.
However, the ball passes through the specific winning opening 8 and flows down in the game section 5 again. Therefore, prize balls are not discharged. Further, in this embodiment, the signal sent from the detector 26 of the specific winning opening 8 becomes a starting condition satisfaction signal (first specific winning signal) of the normal symbol display device 10 described later. The specific winning opening 8 may have any configuration as long as the detector 26 can detect a hit ball and send a signal, and the structure and the mounting position of the detector 26 are not limited, and the detected hit ball is taken in as a prize ball. It may be configured such that prize balls are discharged at.

Normally, the symbol display device 10 converts and displays symbols (numerals) such as symbols and numbers under the control of the electric control device 23 at a speed that cannot be visually recognized, and the symbols when the conversion display is stopped are displayed. If the stop display mode is set in advance, the bonus is given to the player. The normal symbol display device 10 shown in the drawing is composed of a 7-segment display device, 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 winning device 7 into a state advantageous to the player is established. Let That is, the normal symbol display device 10 in the present embodiment is the first by the first specific winning signal from the first specific winning signal generating means (detector 26).
It functions as a part of a first variable winning device operating condition forming means for determining formation of operating conditions of the variable winning device 7. Then, as will be described later, the probability that the prize mode is formed is adjusted by comparing a preset reference base value with a current base value calculated in an actual game, and thereby the first variable winning device 7 The winning probability is adjusted, and as a result, the current base value in the actual game approaches the set reference base value. In addition, the normal symbol display device 10 not only variably displays the symbols, but also sequentially blinks a plurality of lamps and forms a prize mode when the blinking movement is stopped by a predetermined lamp and continuously lit. You may comprise.

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. And the first
A detector 30 that detects a hit ball that has won the variable winning device 7 and sends a signal to the electric control device 23 is provided facing the flow path of the winning ball. In addition, in the present embodiment, in addition to detecting the number of winning balls of the hit ball that has won the first variable winning device 7, the first variable winning device 7 functions as a second specific winning port, and the detector 30 is a special It functions as a second specific winning signal generating means (special symbol starting winning switch) for generating a second specific winning signal which is a starting condition of the symbol display device 6.

Therefore, when a hit ball is won when the first variable winning device 7 is in the first state or the second state, the detector 30 as the second specific winning signal generating means detects the winning ball and the electrical control device is operated. The second specific winning signal is sent to 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 as a winning ball on the ball supply tray 15. Is discharged. As described above, when a hit ball is won in the first variable winning device 7, a predetermined number of prize balls are given, and a privilege is also given based on the second specific winning signal from the 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 the present 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 (numerical symbols) such as symbols and numbers at a speed that cannot be recognized by 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 bonus 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.
It is converted to a state and is performed until a predetermined termination condition is satisfied.

The second variable prize device 9 shown in FIG. 9 is a so-called attacker, which is a variable prize device.
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 the hit ball is not accepted and a second state in which the 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. A continuation detector 42 for sending a continuation signal is provided at 23. 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 prize 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, the cycle is updated until one of the conditions until a predetermined number (for example, 10) of hit balls is established is satisfied, and the hit ball enters 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 electric control device 23 having a microcomputer structure for controlling the game will be described. The player operates the firing control handle 1
When the hitting ball launching device 11 is actuated by operating 2, the ball introduced from the ball feeding tray 15 is fired to one and is supplied to the upper part in the game section 5 for the actual game. In this way, when the hitting ball launching device 11 launches balls one after another (for example, 100 balls per minute), the launching ball sensor 22 detects one ball, and the launching ball signal is effectively launched by the electrical control device 23 each time. When the hit ball is a foul, the foul ball signal is sent to the effective firing ball number calculation means 51 every time the foul ball sensor 25 detects a foul ball.

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
Calculates the actual base value at the present time, that is, the current base value. Therefore, the base value comparison / determination means 53
In, by comparing the calculated base value (current base value) with a preset reference base value, it is possible to determine whether or not the operation of the gaming machine 1 is currently on schedule.

A hit ball shot in the game section 5 hits an obstacle nail while flowing down while converting the down-flow direction, and when this hit ball passes through the first specific winning opening 8, a detector as a normal symbol starting winning detection switch. 26 detects the hit ball and sends a first specific winning signal to the electric control device 23. In addition, when the hit balls successively pass through the specific winning opening 8, a predetermined number may be stored in the electric control device 23 and the stored number may be visually displayed to the player.

When the electric control device 23 receives the first specific winning signal, the normal symbol display control means 54 operates to activate the normal symbol display device 10 to start the variable display, and the normal symbol random number generating means 55. Generates a random number and normally determines whether or not this random number is a hit.
Is determined, and the result of this determination is the ordinary symbol display control means 5
Send to 4. Then, when the predetermined time set in the normal symbol display control means 54 elapses, the normal symbol hit determination means 5
Based on the judgment result from 6, that is, when the hit judgment result is received, the display mode of the hit (for example, "7")
To stop at the same time, and when the determination result of the disconnection is received, the display mode of the disconnection (for example, "1" other than "7",
The display symbol is selected so as to stop with "2" ...), and the variable display is stopped at the selected symbol.

However, the above-mentioned base value comparison / determination means 53
When it is determined that the forced hit-and-miss control means 57 should adjust the hit-and-miss based on the result of the judgment, the forced hit-and-miss control means 5 has priority over the judgment of the normal symbol hit judgment means 56.
The hit or miss is controlled by a signal from 7, and is normally sent to the symbol display control means 54. Therefore, even if the random number from the normal symbol random number generating means 55 originally corresponds to the hit, if the forced out-of-contact control means 57 outputs the signal of forced out, the normal symbol display device 10 is If the random number from the normal symbol random number generation means 55 is originally off, the normal symbol display device 10 is stopped with a symbol other than "7". On the other hand, even if the random number from the normal symbol random number generation means 55 is originally out, if the signal of forced hit is transmitted from the forced hit / miss control means 57, the normal symbol display device 10 is "7".
If the random number from the normal symbol random number generation means 55 is originally a hit, the normal symbol display device 10 stops at "7".

The above-described forced out-of-contact control is performed every time the determination result from the base value comparison / determination means 53 is received (in other words, the effective firing ball number calculating means 51 calculates the effective firing ball number to calculate the base value. Each time the means 52 calculates the current base value), it does not forcibly control the hit-and-miss, but a forcible control active including the base-value calculation means 52, the base-value comparison and determination means 53, and the forcible-and-miss control means 57. Conversion means 58
However, if the judgment result reaches a predetermined number of times (the number of sampling reaches a predetermined number), or if the absolute value of the difference between the set reference base value and the actual current base value falls within the predetermined range. You may make it perform a compulsory control when it exceeds.

When the normal symbol display device 10 does not form the prize mode, it does not directly affect the subsequent game, but when the prize mode is formed, the operating condition of the first variable winning device 7 is satisfied. Then, an operation start signal is sent from the normal symbol hit determination means 56 to the normal electric accessory driving control means 59. When the ordinary electric auditors product drive control means 59 receives the operation start signal, it excites the solenoid of the first variable winning device 7 (ordinary electric auditors member) to convert it into the second state in which a ball can be easily hit, and the ordinary electric auditors product. A signal is sent to the open display control means 60, and the normal electric accessory release display control means 60 emits light from the normal electric accessory open indicator 61 such as an LED to visually display it to the player.

When the first variable winning device 7 is converted to 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 the second specific winning signal. Special symbol start winning detector 3 as a generating means
When 0 is detected, the second specific winning signal is sent to the ordinary electric auditors product drive control means 59, the base value calculation means 52, and the starting memory control means 62 of the electric control device 23. Since the hit ball that has won the prize is processed as the prize ball, the ball discharging device 17 operates and a predetermined number of balls are discharged to the ball supply tray 15 as the prize ball. When the prize balls are discharged, the base value at that time changes, so this base value is the special symbol starting prize detector 3
Base value calculation means 5 that has received the second specific winning signal from 0
2 calculates the number of discharged prize balls, and then sends it to the base value comparison / determination means 53. Therefore, when prize balls are discharged due to winning in the first variable winning device 7, the actual base value becomes higher than before. Therefore, in a state where the actual base value is lower than the reference base value, the normal symbol display device 1
If a 0 is hit as a hit, the first variable winning device 7 is won and a prize ball is discharged, and as a result, the actual base value is increased. Further, in a state where the actual base value is higher than the reference base value set in reverse, the actual base value gradually decreases as long as the shot is continuously shot, so that the normal symbol display device 10 If the control for removing the result is performed so that the prize balls are not discharged as much as possible, the actual base value gradually decreases and approaches the reference base value.

In the case of this embodiment, since the winning of the first variable winning device 7 is controlled and the number of prize balls discharged by winning the first variable winning device 7 is used as the basis for calculating the base value, It is desirable to arrange or adjust obstacle nails in the winning opening 63 so that the hit ball hardly wins.
In addition, when the hit ball does not win even if the first variable winning device 7 is converted to the second state, the normal electric auditors product drive control means 59 causes the first electric winning object drive control means 59 to move to the first state because the predetermined time set in the timer 64 has elapsed.
The solenoid of the variable winning device 7 may be demagnetized to return to the first state. Furthermore, even if the first variable winning device 7 is won, the second variable winning device 7 is not immediately returned to the first state by the second specific winning signal from the special symbol start winning detector 30 but is used by the timer. The second state may be maintained until a predetermined time that has been set elapses, or the second state may be maintained until a preset number of hit balls are won. In this way, the number of prize balls discharged based on the prize balls won in the first variable winning device 7 is likely to increase, so that when the actual current base value is lower than the set reference base value, It is possible to approach the reference base value in a short time.

When the normal electric accessory driving control means 59 receives the second specific winning signal from the special symbol starting winning detector 30, the solenoid of the first variable winning device 7 is demagnetized, and the first
The 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. Even if the first variable winning device 7 returns to the first state, there is a possibility that a batted ball will win. If the first variable winning device 7 in the first state wins a batted ball, the same as the above-mentioned winning. , The special symbol table start winning detector 30 detects a winning ball and sends out a second specific winning signal.

When the starting memory control means 62 receives the second specific winning signal from the special symbol starting winning award detector 30, the starting memory display control means 6 stores it based on this memory.
A special symbol display device start right signal is sent to 5, and the start memory display control means 65 is a start memory display 66 composed of an LED or the like.
Is emitted to visually display the special symbol display device starting right to the player. Therefore, when the hit balls successively enter the first variable winning device 7, the starting memory control means 62 stores the second specific winning signal one after another, and the number of memories is visually displayed on the starting memory indicator 66. It

Further, when the starting memory control means 62 receives and stores the second specific winning signal from the special symbol starting prize winning detector 30, the special symbol display controlling means 67 is based on this memory.
And a signal to the random number extracting means 68.

When the special symbol display control means 67 receives a signal from the starting memory control means 62, the operation of the special symbol display device 6 is started based on this signal and the three indicators 31 are displayed.
Numbers are variably displayed on a, 31b, and 31c.

When the random number fetching means 68 receives a signal from the starting memory control means 62, it fetches a random number from the random number table set by the set random number selecting means 69 and sends it to the big hit judging means 70. 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 six levels, and another game is performed based on this set random number table. It is configured.

To set the probability of the special symbol display device 6, the key is inserted into the keyhole of the key 20a provided in the setting operation section. When the key is inserted, the key insertion detector 71 detects the insertion of the key and sends an activation signal to the special symbol probability setting storage control means 72 and the probability setting display control means 73, and the special symbol probability setting storage control With the state that the means 72 can effectively receive the signal from the special symbol probability setting switch 74,
The probability setting display control means 73 is activated to start the display on the special symbol probability setting display 75 which is a 7-segment display.

When the administrator sends a signal to the specific symbol probability setting storage control means 72 by operating the specific symbol display device probability setting switch 74, the specific symbol probability setting storage control means 72 receiving this signal selects a set random number. A signal is sent to the means 69 and a signal is sent to the probability setting display control means 73. The specific symbol probability setting switch 74 may be turned on / off by rotating the key,
It 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 72, the set random number selecting means 69 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 specific symbol probability setting switch 74 is set to "1", the setting random number selecting means 69 selects the special symbol display device random number 1 with a probability of 1/150, and the special symbol probability setting is set accordingly. “1” is displayed on the display 75, and the specific symbol probability setting switch 7
When 4 is set to "2", the set random number selection means 69 selects the random number 2 for the special symbol display device with the probability of 1/200, and "2" is displayed on the special symbol probability setting indicator 75 accordingly. , ..., the specific symbol probability setting switch 74
By operating, you can freely select any random number from the special symbol display device random numbers prepared in advance,
The selected random number type is visually displayed on the special symbol probability setting display 75. Then, according to the business policy, when a random number with a desired probability (for example, the random number 2 for special symbol display device with probability 1/200) is selected and the key is pulled out, the selected random number is fixed. Therefore, the business of the day can be performed in this state.

After setting in this way, when the random number extracting means 68 receives a signal from the starting memory controlling means 62, the random number for the special symbol display device with the probability 1/200 selected by the setting random number selecting means 69 by this One random number is picked up from 2 and sent to the jackpot judging means 70 for judgment.

When the big hit judging means 70 judges that the "off", that is, the prize mode is not formed, a signal is sent to the stop symbol selecting means 76, and the stop symbol selecting means 76 is disengaged from the disengagement symbol generating means 77 (for example, , "3, 1, 5") is selected, and a signal is sent to the special symbol display control means 67 so that the variable display is stopped with this symbol, whereby the special symbol display control means 67 causes the special symbol display device 6 to operate. The variable display is stopped at "3, 1, 5".

On the other hand, when the big hit judging means 70 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 78, and a signal is sent to the stop symbol selecting means 76 to stop it. The symbol selecting means 76 hits the winning symbol from the winning symbol generating means 79 (for example, "7, 7,
7 ") is selected to send a signal to the special symbol display control means 67 so that the variable display is stopped with this symbol, whereby the special symbol display control means 67 causes the variable display of the special symbol display device 6 to be" 7, Stop at 7,7 ".

When the big hit control means 78 receives the big hit signal, it sends a signal to the base value calculation means 52 to suspend 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, the base value calculation means 52 does not calculate the current base value, so the forced hit / miss control means 57 also temporarily stops the operation, and the forced control of the normal symbol display device 10 is performed. Instead, the prize mode is formed as usual according to the random number generated by the normal symbol random number generation means 55.

When the big hit control means 78 receives the big hit signal, it sends a signal to the big winning opening drive control means 81. Based on this signal, the big winning opening drive control means 81 causes the solenoid of the second variable winning device 9 to operate. Excited, 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 78 receives the jackpot signal, the cycle number indicator 82 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 81 and the big hit. A signal is sent to the control means 78, and on the basis of this signal, the big hit control means 78 counts the number of winning balls in the cycle and visually displays it on the winning number indicator 83. By the time the number of prizes to be paid to the second variable winning device 9 in the first cycle reaches a predetermined number (for example, 10) or a predetermined time (for example, 28 seconds) set in the timer in the jackpot control means 78 has elapsed. When the hit ball does not enter the continuous winning hole 39, the jackpot control means 78 ends the special game based on the fact that either one of the ending conditions is met, but the hit ball is hit before these ending conditions are met. When the player wins the continuous winning opening 39, the continuation detector 42 detects a winning ball to the continuous winning opening 39, and the special winning opening drive control means 81.
And a continuation signal is sent to the jackpot control means 78. In addition, when the special game ends when the ending condition is satisfied without a hit ball winning the continuous winning opening 39, the big hit control means 78 sends a signal to the base value calculating 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 hitting the continuous winning opening 39 with a hit ball, the continuation indicator 43 emits a light to visually indicate to the player that the continuation condition is satisfied, and the special winning opening is driven. The control means 81 once demagnetizes the solenoid of the second variable winning a prize device 9 to return to the first state, and after the lapse of a predetermined wait time, again excites the solenoid of the second variable winning a prize device 9 to convert it into the second state. Further, the big hit control means 78 resets the winning number display 83 to zero and updates the display of the cycle number display 82 to visually display, for example, "2". When the cycle is actually updated, the continuation indicator 43 is turned off.

In this way, by hitting the ball into the continuous winning opening 39, the cycle is updated and the special game is continued, and this cycle is updated 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 operating by a signal from the big hit control means 78, and returns to the normal game state, as in the case where the special game ends.

As described above, in this embodiment, the base value which is 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 normal symbol display device 10 is forcibly hit, thereby creating a state in which the first variable winning device 7 makes it easy for the hit ball to win, thereby increasing the winning probability. The number of balls discharged is increased, so that the actual base value rises and is controlled so as to approach the reference base value. On the other hand, when the base value in the actual game is higher than the reference base value, the normal symbol display device 1
Even if the number of effective firing balls increases with the continuation of the game, the deviation of 0 is forcibly released, and thus the increase in the winning probability to the first variable winning device 7 is suppressed, and the number of winning balls discharged is thereby reduced. It is controlled so that the actual base value gradually decreases and approaches the reference base value. Therefore, obstacle nails (especially life nails that usually affect the winning probability to the first variable winning device 7)
Even if the value is not adjusted, the base value obtained as an actual business result approaches the base value planned in advance, and the business can be stabilized. Since the prize mode formation probability of the special symbol display device 6 can be set to a desired probability, the individuality of each gaming machine 1 can be created by this setting, and the payout rate and the divisor can be adjusted by this. You can

In the above-described embodiment, the reference base value remains fixed and the desired base value cannot be set. However, the reference base value is the gaming machine 1
A desired value may be freely set according to each business policy, or a base value prepared in stages may be selected and set. For example, as shown in FIG. 11, when the reference base value is selected and set from the prepared base values, the key is inserted into the keyhole of the key 20b provided in the setting operation unit 19. When the key is inserted, the key insertion detector 84 detects the insertion of the key and the special symbol probability setting storage control means 72 and the probability setting display control means 73.
And the activation signal is sent to the base value setting storage control means 84 and the base value setting display control means 85, and the special symbol probability setting storage control means 72 can effectively receive the signal from the special symbol probability setting switch 74. At the same time, the probability setting display control means 73 is activated to start displaying on the probability setting display 75 which is a 7-segment display, and the base value setting storage control means 84 validates the signal from the base value setting switch 86. Then, the base value setting display control means 85 is operated to display the reference base value visually on the base value setting display 87 which is a 7-segment display. Therefore, if the special symbol probability setting switch 74 is operated, the probability of hitting in the special symbol display device 6 can be selected and set from six special symbol display device random numbers, as in the above-described embodiment.

When the administrator operates the base value setting switch 86 to send a signal to the base value setting storage control means 84, the base value setting storage control means 8 which has received this signal.
4 sends a signal to the reference base value selection means 88 and also sends a signal to the base value setting display control means 85.

Upon receipt of the signal, the reference base value selection means 88 selects one of the base values 1 to 6 stored in advance, which corresponds to the signal. These base values are, for example, “35” for the base value 1, “45” for the base value 2, “50” for the base value 3, “55” for the base value 4, “60” for the base value 5, and 6 for the base value. Is "7
It is set to "0". Therefore, for example, the display of the base value setting indicator 87 is set to "1" by the base value setting switch 86.
When the reference base value selecting means 88 selects the reference base value 1 of “35”, and the base value setting display 87 displays “3”, the reference base value selecting means 88 displays “3”. By selecting the reference base value 3 of “50”, ..., By operating the base value setting switch 86, an arbitrary base value can be selected from the prepared reference base values, and the selected base value is the base value. It is visually displayed on the setting display 87. 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 compared with the base value comparing / determining means 53.
Sent to. Therefore, the base value comparison / determination means 53 compares the reference base value with the current 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 hitting 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 set reference base value from the reference base value selection means 88. The base value comparison / determination means 53 compares and. Then, when the base value from the base value calculation means 52 is less than "45" with respect to the set reference base value "45",
The base value comparison / determination means 53 determines that the base value of the actual game is low, and sends a signal to that effect to the forced hit / miss control means 57. Therefore, in this state, when the hit ball passes through the specific winning opening 8 and the detector 26 sends out the first specific winning signal, the random number from the normal symbol random number generating means 55 is given priority, and the signal from the forced hitting-off control means 57 is given. Based on this, the normal symbol display control means 54 stops the conversion display of the normal symbol display device 10 with the winning symbol to forcefully hit.

When the conversion display of the normal symbol display device 10 is stopped at a hit, for example, "7", the first variable winning device 7 is converted to the second state as described above. First variation winning device 7
When the ball is converted into the second state, it becomes easier to win the ball, and when the ball is actually won in the first variable winning device 7, the ball is processed as the winning ball and a predetermined number (for example, 7) is discharged from the ball ejecting device 17. No. sphere is discharged as a prize ball, and the base value calculation means 52 which has received a signal from the detector 30 which has detected the winning ball calculates the base value again by adding the number of prize balls (7 pieces). Therefore, the current base value rises.

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 in a high state, and a signal to that effect is sent to the forced hit / fall control means 57. Therefore, in this state, when the hit ball passes through the specific winning opening 8 and the detector 26 sends out the first specific winning signal, the normal symbol random number generating means 5
The normal symbol display control means 54 stops the conversion display of the normal symbol display device 10 with the symbol which is off based on the signal from the forced hit-and-off control means 57 in priority to the random number from 5, and forcibly removes it. Therefore, the first from the detector 26
Even if the random number generated by the normal symbol random number generation means 55 based on the specific winning signal is a winning random number, the first variable winning device 7 is not converted to the second state. In other words, the seven prize balls that would have been won without being forcibly controlled will not be ejected, and the number of effective balls will increase during this period as well.
As a result, the current base value will be forcibly adjusted to the lower side.

As in the above-described embodiment, when the absolute value of the judgment result of the base value comparison / judging means 53 becomes a predetermined value, the forced hit-off control is effectively operated. Good. For example, the reference base value selection means 88
The forced out-of-contact control means 57 is operated only when the difference between the reference base value selected in step 1 and the current base value calculated by the base value calculation means 52 exceeds a predetermined value (for example, 0.5). Good. That is, the base value from the base value calculating means 52 is "44.5" or less, or "4" with respect to the base value "45" from the reference base value selecting means 88.
When the absolute value of the difference between the reference base value and the current base value exceeds “0.5”, the base value comparison / determination means 53 determines to the forced hit / fall control means 57. A signal may be sent, and the forced hit-off control means 57 may control the outcome of the game in the normal symbol display device 10 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 88 and the special symbol display device random number selected by the probability setting random number selection means 69 is 6 × 6 = 36. There are various combinations, and this combination can be appropriately selected. In this case, the random number for the special symbol display device has a high probability (for example, probability 1 /
When the random number 1) for special symbol display device of 150 is selected, the probability that the right to the special game is generated is increased, the number of prize balls discharged is remarkably increased within a short time, and the payout rate (divided number) is increased. , In other words, in a short time, the profit obtained by the player side suddenly becomes large and the profit obtained by the game store side becomes sharply small. On the contrary, the random number for the special symbol display device has a low probability (for example, probability). If you select 1/350 random number for special symbol display device 6), the probability that the right to special game will be generated is extremely low, and the number of prize balls discharged will be remarkably increased within a short time, and the winning rate (divided number) Is almost never sharply increased, in other words, the profit earned by the player in a short time is rapidly increased and the profit earned by the game store is drastically reduced. Also,
High base value (for example, base value "7
If you select "0"), you can play at a rate that 70 prize balls are ejected if you shoot 100 balls on average, even if no special game is played. It becomes a state where the player can continue playing the game (a state where the ball is good), and on the contrary, when a low base value (for example, the base value “35”) is selected as the reference base value, the average is 10
Since it is possible to play the game at a rate that 35 prize balls are discharged by firing 0 balls, the game is finished in a relatively short time (a state where the ball does not feel good). 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, at the time of opening a new store, the reference 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 lower the probability of random numbers for special symbol display devices by setting the reference base value high or set it 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 and the reference base value of each gaming machine 1 may be set by separate operations according to the business policy, but a plurality of combinations (sales mode) are set in advance. It may be configured so that when the business mode is selected, the special symbol display device random number and the reference base value can be automatically set.

In the embodiment shown in FIG. 12, the electric control device 23 is provided with a mode setting storage control means 91, a mode setting display control means 92, etc., and the mode setting storage control means 91 has a special symbol display device random number and a reference base. Plural kinds of combinations of values are determined in advance. For example, the random number 1 for special symbol display device in the "newly opened store mode", which is also called "mode 1"
(Probability 1/150) and the reference base value 6 of "70" are combined, and the "play mode 1", which is also called "mode 2", is a special symbol display device random number 5 (probability 1/300) and the reference base value The combination with 5 of "60", the combination of the random number 4 (probability 1/250) for the special symbol display device and the reference base value 4 of "55" in the "play mode 2", which is also called "mode 3", Another name for "Mode 4""Game mode 1" is a special symbol display device random number 1 (probability 1/150) and reference base value 1
The combination with “35” of “No. 2” for special symbol display device (probability 1/2
00) and the standard base value 2 “45”,
The "collection mode", which is also known as "mode 6", includes a random number 6 (probability 1/350) for the special symbol display device and a reference base value "3".
5 "is set in advance. The other configuration of the electric control device 23 shown in FIG. 12 is similar to that of the above-described embodiment.

When a key is inserted into the keyhole of the key 20 provided in the setting operation section 19, the key insertion detector 93 detects the insertion of the key and activates the mode setting storage control means 91 and the mode setting display control means 92. A signal is sent to both of these control means 91, 9
When 2 is activated and the business mode setting switch 94 is operated, any one of the "mode 1" to "mode 6" business modes can be selected by a signal from the business mode setting switch 94. Then, when one business mode (for example, "mode 2") is selected by the mode setting storage control means 91, a signal indicating the business mode is displayed as the mode setting display control means 92, the probability setting random number selecting means 69, and the reference base. It is sent to the value selection means 88.

When the mode setting display control means 92 receives a signal from the mode setting storage control means 91, the business mode, for example, "mode 2" is visually displayed on the mode setting display 95. Therefore, the administrator can surely perform the work of setting the business mode while checking the display of the mode setting display 95.

When the probability setting random number selection means 69 receives a signal from the mode setting storage control means 91, it selects the random number for the special symbol display device according to the signal. For example, when "mode 2" is set, the special symbol display device random number 5 (probability 1/300) is selected.

When the reference base value selection means 88 receives a signal from the mode setting storage control means 91, it selects a reference base value corresponding to the signal. For example, "mode 2"
When the setting is made, the reference base value 5 “60” is selected and the 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 10, the first variable winning device 7 is won, and the second specific winning signal is sent. The variable display result on the special symbol display device 6 has a probability of 1/300.
It is controlled by the special symbol display device random number 5.

In each of the above-described embodiments, when the current base value is calculated by the base value calculation means 52, the first variable prize is detected based on the second specific winning signal that detects the hit ball hit by the first variable prize device 7. Although the ratio of the number of discharged prize balls based on the winning to the device 7 and the number of effective fired balls from the effective fired ball number calculation means 51 is calculated, the calculation of the base value in the present invention is not limited to this. The base value may be calculated from the number of discharged prize balls and the number of effective shot balls in the normal game state excluding the number of discharged prize balls and the number of effective shot balls in the special game state in which the winning probability is remarkably increased.

For example, as shown in FIG. 4, ball detectors 96 ... Are provided in the general winning openings 63 ... In which prize balls are discharged when a hit ball wins, or the winning openings 63 ... A ball detector 96 is provided in the flow path through which the winning balls flow down, the number of prize balls discharged in the normal game state is calculated based on signals from these detectors 96, and the base value is calculated using this number of prize balls discharged. It may be calculated. In this way, the original base value can be calculated more accurately by calculating the base value by taking into consideration the number of prize balls discharged by winning the prize other than the first variable winning apparatus 7. However, in the gaming machine 1 in which obstacles are arranged such that most of the prizes are paid to the first variable prize device 7 and the prizes to the other prize holes 63 are extremely reduced, the first variable prize device is used. Even if the winning of 7 is detected and the base value is calculated using the number of discharged prize balls based on the winning of the first variable winning device 7, the purpose can be achieved.

In the case of the gaming machine 1 in which the number of prize balls discharged for one winning is the same, the number of prize balls × n
The number of discharged prize balls is calculated by (for example, n = 13). If the prize value and the number of discharged prize balls differ depending on the winning openings, the number of discharged prize balls is calculated and then added.
When the ball discharging device 17 is provided with a discharged ball detector (not shown), the number of prize balls actually discharged is detected by a signal from this discharged ball detector, and based on this, The current base value may be calculated by

In calculating the base value, the effective denominator is used as the denominator (the number that becomes the base of the base value), which is the number that is disadvantageous to the player required for the game, but 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 22 and 25. 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.

In the above embodiment, in order to bring the current base value in the actual game closer to the reference base value,
The probability that the first variable winning device 7 is converted to the second state is controlled by controlling the so-called outcome of the normal symbol display device 10, but the time that the first variable winning device 7 continues to be converted to the second state is The current base value may be forcibly increased or decreased by controlling the number of winning balls to the first variable winning device 7, that is, the number of winning balls discharged, by expanding and contracting. Further, in order to bring the current base value in the actual game closer to the reference base value, the number of prize balls discharged by winning the first variable winning device 7 is made variable, and the current base value is higher than the reference base value. It may be adjusted by increasing the number of prize balls discharged when it is low, and conversely by decreasing the number of prize balls discharged when the current base value is higher than the reference base value. In short, the normal return rate correction means for performing control to bring the current base value closer to the reference base value controls the operation probability of the first variable winning device 7 forming a part thereof, or Control the operating time, control the number of prizes to the first variable winning device 7,
A configuration may be used in which the number of prize balls discharged for the prize balls to the first variable winning device 7 is controlled.

When the first variable winning device 7 is converted into the second state, the second state is returned to the first state if a predetermined number of hits are won, and the predetermined number is used as a reference. The current base value may be made closer to the reference base value by increasing or decreasing based on the magnitude of the difference between the base value and the current base value, thereby increasing or decreasing the number of prize balls discharged.

In the above-mentioned embodiment, the variable display of the special symbol display device 6 is stopped to form the prize mode as the condition for generating the right of the special game, but the present invention is limited to this game content. Not a thing. For example, when a hit ball wins a specific starting winning opening, the variable winning device 9 converts the first state in which the hit ball is not accepted for a relatively short predetermined time to a predetermined number of times into a second state in which it is easy to accept the hit ball, and in this second state First, a special game right is generated by a hit ball winning a specific right generation winning opening, and in the special game, the variable winning device does not accept the hit ball for a predetermined time or a predetermined number of times.
The state is changed to a second state in which it is easy to accept a hit ball, and in this second state, the special game can be continued on condition that the hit ball wins the continuous winning hole 39 (may be the same as the right occurrence winning hole). May be. In this case, a variable winning device is used for the starting winning opening, and a normal symbol display device for performing variable display by hitting or passing through the specific winning opening and the specific winning opening is provided, and the reference base value and the actual Compare the current base value of the game, and control the outcome of the normal symbol display device based on the comparison result to convert the variable winning device from the first state where the hit ball is difficult to enter to the second state where the hit ball is easy to enter The current base value may be controlled, or the duration of the second state and the number of conversions of the variable winning device, which is the starting opening, may be forcibly controlled without providing the normal symbol display device.

Further, in any of the above embodiments,
Due to the occurrence of the right to the special game, the second variable winning device is not limited to the one that is changed from the first state, which is disadvantageous to the player, to the second state, which is advantageous to the player to start the special game. The second variable winning device may be converted from the first state to the second state on condition that the hitting ball is won at the opening condition satisfied starting port after the right is generated.

In the present invention, the setting operation section 19 for setting the probability of the special symbol display device 6 and the reference base value is not limited to the above-mentioned embodiment.

[0072]

As described above, according to the present invention, the operating index intended by the game store can be set according to the model and the business policy of the game machine based on the external setting operation without fine adjustment of the obstacle nail.
