The game board 2 is provided with a game area 8 surrounded by a guide rail 7 formed in an arc shape. An upper tray 4 is provided below the game board 2, and a lower tray 5 is provided below the upper tray 4.

The upper receiving tray 4 is for storing the lent out balls and the paid out balls, and for supplying the launching device 6 with the balls for launching into the game area 8. When the upper tray 4 is filled with a predetermined amount of balls, the dispensed ball is sent to the lower tray 5.
The launching device 6 is provided on the right side portion of the lower tray 5, and the portion operated by the player is formed in a handle shape. The player fires a ball by operating the handle-like portion. The ball fired by the launching device 6 is sent along the guide rail 7 into the game area 8 along the guide rail 7.

In FIG. 2, the game area 8 is provided with a symbol starting winning opening 11, a general winning opening 12, and a special winning opening 13.
Here, in this embodiment, a variable winning opening and a general winning opening are provided as winning holes for paying out the winning balls based on winning of the balls.
The “variable winning opening” is a winning opening in which an accessory is activated when a predetermined condition is satisfied, and an entrance is opened or enlarged.
On the other hand, the “general winning opening” is a winning opening (a winning opening unrelated to the operation of the accessory) whose entrance is not opened or enlarged and whose size is fixed.
In this embodiment, the symbol starting winning port 11 and the special winning port 13 are provided as variable winning ports. In addition, a general winning opening 12 is provided as a general winning opening.

The symbol starting winning opening 11 pays out a predetermined number of balls to the player every time there is a winning of a ball, and a winning opening for starting the variation display of the symbol displayed on the symbol variation display device 31. It is.
When the ball is won at the symbol starting winning slot 11, the lottery means 52 (described later) performs a winning / non-winning lottery or the like in the ball game machine 1, and the symbol to be stopped is displayed based on the lottery result. At the same time, the determined symbol is stopped and displayed on the symbol variation display device 31.

If the symbol variation display device 31 is in the symbol variation display or special game when the symbol start winning slot 11 is won, the symbol variation display is not immediately started but the winning information is stored and held. Keep it. In this case, the number of reserved balls is stored up to a maximum upper limit value (for example, 4).
When the variation of the symbol on the symbol variation display device 31 can be started, if the reserved ball is stored, the variation display of the symbol based on the reserved ball is started.

The general winning opening 12 is a winning opening for paying out a predetermined number of balls to the player every time there is a winning of a ball.
Furthermore, the special prize opening 13 is a relatively large prize opening that is not opened during normal games but is opened only during special games. Each time a ball is won at the time of opening, a predetermined number of balls are paid out.
When the symbol stopped and displayed by the symbol variation display device 31 is a special symbol such as “777”, the game shifts to a special game. And if it shifts to this special game, the special winning opening 13 will be open | released.

In addition, a symbol variation display device 31 is provided in the approximate center of the game area 8.
The symbol variation display device 31 performs image display including symbol variation display using a liquid crystal display or a dot display. When a ball wins the symbol starting winning slot 11, an image including a symbol (for example, a character, a figure, a symbol, or a number) changes, and then a predetermined symbol is stopped and displayed.

The enlarging member 36 is for enlarging the entrance of the symbol start winning port 11, and is provided integrally with the symbol start winning port 11 at the entrance of the symbol starting winning port 11. The expansion member 36 is provided with a pair of symmetrical members.
In FIG. 2, the enlarged member 36 indicated by a broken line shows a state in which the size of the entrance of the symbol starting winning opening 11 is slightly larger than the size of a sphere, for example.
On the other hand, the enlarged member 36 shown by a solid line shows a state in which a symmetrical member spreads outward and the entrance of the symbol starting winning opening 11 is enlarged. When the expanding member 36 is arranged as shown by the solid line, it becomes easy to win a ball in the symbol starting winning opening 11.

  Moreover, the normal symbol starting ports 14 are provided on the left and right sides of the symbol variation display device 31. The normal symbol start port 14 is formed so that a sphere simply passes and a passed sphere is detected. Even if the normal symbol starting port 14 is passed, the prize ball is not paid out. When the passage of the ball of the normal symbol starting port 14 is detected, whether or not to expand the entrance of the symbol starting winning port 11 is selected in the inside of the ball game machine 1.

Further, an ordinary symbol variation display device 34 is provided below the special winning opening 13.
The normal symbol fluctuation display device 34 is for displaying the symbols in a variable manner (rotation display and stop display) based on the detection of the passage of the sphere of the normal symbol start port 14. As described above, when the passage of the ball of the normal symbol start port 14 is detected, whether or not to enlarge the entrance of the symbol start winning port 11 is selected by lottery, and the lottery result is displayed.

In the present embodiment, the normal symbol variation display device 34 displays symbols (numbers) by 7 segments, and the lottery result is any one of “5”, “6”, and “7” at the time of stop display. Display the symbol. When the symbol “5” or “6” is stopped and displayed, it indicates that the lottery result is not won, and when the symbol “7” is stopped and displayed, it is determined that the symbol has been won as a result of the lottery. Show.
When the symbol “7” is stopped and displayed, the enlarging member 36 is driven by the operation of the accessory, and the entrance of the symbol starting winning port 11 is expanded for a certain period of time. Thereafter, the original state is restored again.

If the normal symbol variation display device 34 is displaying the symbol variation when the ball has passed through the normal symbol start port 14, the symbol variation display is not immediately started, but is stored and held. deep. In this case, the number of reserved balls is stored up to the maximum upper limit value (four in this embodiment).
When the normal symbol variation display device 34 can start the variation of the symbol, if the reserved ball is stored, the variation display of the symbol based on the reserved ball is started.

Next, the control of the ball game machine 1 in this embodiment will be described. FIG. 3 is a block diagram showing functions of the ball game machine 1 according to the first embodiment, and mainly shows a portion according to the present invention.
The game control means 50 is a means for comprehensively controlling the entire ball and ball game machine 1 including the progress and effects of the game. The game control means 50 includes a CPU that performs calculations, a ROM that stores programs necessary for the progress of the game, data for production, and the like, and data that is captured when the CPU performs various controls. RAM and the like that are temporarily stored.

The game control means 50 includes the following means. In addition, each means shown below has shown the part mainly related to this embodiment, and is not limited to the means shown in figure.
The winning ball detecting means 51 detects when a ball has won the symbol starting winning port 11, the general winning port 12, and the special winning port 13, respectively. Each of the symbol start winning opening 11, the general winning opening 12, and the special winning opening 13 is provided with a starting winning opening sensor 21, a general winning opening sensor 22, and a special winning opening sensor 23, which detect a winning ball. It is electrically connected to the means 51.

  Here, the start winning port sensor 21 is a sensor that is provided at the entrance of the symbol starting winning port 11 and constantly monitors the winning of a ball to the symbol starting winning port 11. When a ball wins the symbol starting winning opening 11, the starting winning opening sensor 21 is passed. As a result, the detection signal at that time is transmitted from the start winning opening sensor 21 to the winning ball detecting means 51. When this detection signal is received, the winning ball detecting means 51 detects that a ball has won the symbol starting winning port 11.

  Similarly, the general winning port sensor 22 and the special winning port sensor 23 are provided at predetermined positions of the entrance portion of the general winning port 12 and the special winning port 13, respectively. This sensor constantly monitors winnings. When a ball wins the general winning opening 12 or the special winning opening 13, it passes through the general winning opening sensor 22 or the special winning opening sensor 23, respectively. Thereby, the detection signal at that time is transmitted to the winning ball detecting means 51 from the general winning hole sensor 22 or the special winning hole sensor 23, respectively. When receiving this detection signal, the winning ball detecting means 51 detects that the ball has won the general winning port 12 or the special winning port 13, respectively. The special winning opening sensor 23 may monitor the winning of a ball to the special winning opening 13 only during the special game.

The lottery means 52 is a lottery for winning or non-winning, a lottery for a stop symbol, and a lottery for a variation pattern on condition that the winning ball detecting means 51 detects a winning of a ball to the symbol start winning slot 11. Is to do.
First, the lottery means 52 includes a lottery means 52a for performing a lottery for winning or not winning. The winning lottery means 52a determines, for example, whether there is a winning based on a random number generating means (soft random number, etc.), a random number acquiring means for acquiring a random number generated by the random number generating means, and a random value acquired by the random number acquiring means Determination means.

  The random number generation means generates a random number (winning determination random number) having a predetermined cycle by a control program or the like. The random number obtaining means obtains the random number generated by the random number generating means at a predetermined time, in this embodiment, when the winning ball detecting means 51 detects that a ball has been won in the symbol starting winning opening 11. The determination means determines whether the random value acquired by the random number acquisition means is a winning or non-winning. Of the random numbers having a predetermined period generated by the random number generation means, a winning random value is determined in advance. Then, if the random value acquired by the random number acquisition means matches the winning random value, it is determined to be winning, and if it does not match, it is determined not to win.

In the present embodiment, the winning probability value in the lottery by the winning lottery means 52a is the first winning probability value (in this embodiment, 1/300) and the second winning probability value lower than the first winning probability value (this embodiment) In the form, 1/400). For example, while determining a plurality of winning random numbers when set to the first winning probability value, the number of winning random values when set to the second winning probability value is set to the first winning probability value. If it is set to less than the number of winning random numbers.
The case where the winning probability value in the lottery by the winning lottery means 52a is set to the first winning probability value or the second winning probability value will be described later.

  Secondly, the lottery means 52 includes a stop symbol lottery means 52b for lottering a stop symbol to be stopped and displayed on the symbol variation display device 31 based on the determination result of the winning or non-winning. The stop symbol lottery means 52b selects the winning symbol as the stop symbol when it is determined that the winning symbol is determined. On the other hand, the stop symbol lottery means 52b selects a non-winning symbol as a stop symbol when it is determined that it is not winning.

  For example, when the stop symbol is composed of three numbers such as left, middle, and right (numbers, letters, figures, symbols, etc.), and all three numbers are the same as the winning symbol The winning symbol is a stop symbol such as “333” or “777”. On the other hand, the non-winning symbol is a stop symbol such as “135” or “330” in which the three numbers are not the same.

  As a lottery of the stop symbol by the stop symbol lottery means 52b, a random number for stop symbol selection is generated using a soft random number by the same method as the winning lottery means 52a, and any one random number value is obtained, and the random value The stop symbol corresponding to is selected.

  Furthermore, the lottery means 52 thirdly includes a fluctuation pattern lottery means 52c for lottery of a variation pattern during the symbol variation display based on the determined stop symbol. A plurality of types of variation patterns are provided and stored in a variation pattern data table (corresponding to the variation pattern storage means of the present invention) 52d. In the variation pattern lottery, a random number for variation pattern selection is generated by using a soft random number in the same manner as the winning lottery means 52a, one random number value is obtained, and the variation pattern corresponding to the random number value is varied. The pattern data table 52d can be selected.

In the present embodiment, at the start of the variable display of symbols, all three numbers such as left, middle and right are displayed in a variable manner, and then stopped and displayed in the order of left, middle and right. Stop displaying numbers.
At this time, when the number on the left and the number in the middle of the three numbers are the same, control is performed so as to display the reach state. Here, the reach state refers to a state in which a winning symbol is obtained when the right number and the like match the left and middle numbers and the like, and the winning symbol is likely to be a winning symbol.

  For example, when the selected stop symbol is a winning symbol such as “333” or “777”, or the left and middle numbers are the same as “330” or “778”, but the symbol is not a winning symbol. In some cases, the left and middle numbers are stopped, and the right number is variably displayed to indicate that it is in a reach state. Then, when such a stop symbol is selected, a variation pattern for displaying the reach state is selected. In this variation pattern, a plurality of variation patterns having different reliability, which are finally stopped and displayed with the winning symbol, are provided in advance. For example, it is possible to provide a low probability variation pattern with a low probability of being stopped and displayed on the winning symbol and a high probability variation pattern with a high probability of being stopped and displayed on the winning symbol.

In this case, when the winning symbol is selected by the stop symbol lottery means 52b, the variation pattern lottery means 52c selects the high probability variation pattern with a higher probability than the low probability variation pattern.
On the other hand, when the non-winning symbol is selected by the stop symbol lottery means 52b, the variation pattern lottery means 52c selects the low probability variation pattern with a higher probability than the high probability variation pattern.

  Further, in the present embodiment, the variation pattern includes a plurality of first variation patterns in which the reference time from the start to the end of the symbol variation display is set to the first time (for example, 5 seconds), and the first variation pattern longer than the first time. It is roughly divided into a plurality of second fluctuation patterns set to 2 hours (for example, 8 seconds). The selection rates of the first variation pattern and the second variation pattern will be described later.

The symbol variation control means 53 controls the symbol variation display device 31 to display the symbol variation on the condition that the winning ball detection means 51 detects the winning of the ball to the symbol starting winning slot 11. Is.
The symbol fluctuation control means 53 performs symbol fluctuation display and stop display by the symbol fluctuation display device 31 based on the lottery result of the lottery means 52. That is, the symbol variation control means 53 performs control so that the symbol variation display is performed according to the variation pattern selected by the variation pattern lottery means 52c and the stop symbol selected by the stop symbol lottery means 52b is finally stopped and displayed. To do.

The prize ball payout control means 54 controls the driving of the prize ball payout device 32 for paying out the prize balls. As described above, when the winning ball detecting means 51 receives the detection signals from the start winning port sensor 21, the general winning port sensor 22, and the special winning port sensor 23, the number of balls corresponding to the winning is paid out. In this way, the prize ball payout device 32 is controlled. When the prize ball payout device 32 is driven, the prize ball is paid out to the upper tray 4 or the lower tray 5 of the ball game machine 1.
In this embodiment, the number of payout balls of the symbol starting winning port 11, the general winning port 12, and the special winning port 13 varies. This will be described later.

  In the special game control means 55, the random number value (winning determination random value) acquired by the lottery means 52 matches the winning random number value, and the symbol stopped and displayed by the symbol variation display device 31 is the winning symbol (for example, “777”). ”), The game is shifted from the normal game to the special game, and the special game is executed until the end condition is satisfied.

First, the special game control means 55 executes a unit game in which the special winning opening 13 is kept open until a predetermined condition is satisfied. Here, the special game control means 55 controls the driving of the special prize opening driving device 33 to open the special prize opening 13.
Further, “until a predetermined condition is satisfied” means that the number of balls that have won the special prize opening 13 has reached a specified number (10 in this embodiment) or the opening time of the special prize opening 13 is a predetermined time ( In the present embodiment, until 30 seconds) is satisfied.

Therefore, the special game control means 55 determines whether or not a predetermined condition is satisfied, and the special game control means 55 counts the number of balls won in the special prize opening 13 during the unit game, and the special prize opening 13. And an opening time measuring means for measuring the opening time.
As described above, when a ball wins the special winning opening 13, it passes through the special winning opening sensor 23, and a detection signal at that time is transmitted from the special winning opening sensor 23 to the winning ball detecting means 51. When receiving this detection signal, the winning ball detection means 51 detects that a ball has won the special winning opening 13. The winning ball number counting means increments and stores this count value by one each time the winning ball detecting means 51 detects a winning of a ball to the special winning opening 13.

  The opening time measuring means measures the time from when the unit game is started and the special prize opening 13 is opened, and has a timer, for example. When the unit game is started and the special prize opening 13 is opened by the special prize opening driving device 33, the timer is activated to start the measurement of the opening time.

  The special game control means 55 satisfies either when the number of winning balls counted by the winning ball number counting means reaches a prescribed number or when the time measured by the opening time measuring means reaches a predetermined time. When it is determined that the predetermined condition is satisfied, the special winning opening 13 is controlled by closing the special winning opening 13 by controlling the driving of the special winning opening driving device 33.

  In addition, the special game control means 55 performs control so that the unit game is executed again within the range of the upper limit number of consecutive unit games when the continuation condition is satisfied in the unit game. In other words, the special game control means 55 permits the execution of the unit game again on condition that the continuation condition is satisfied in the unit game and the upper limit number of consecutive unit games is not exceeded.

Here, a special area (not shown) is provided in advance in the special winning opening 13, and when it passes through this specific area, it is determined that the continuation condition is satisfied in the unit game.
A specific area sensor 27 is provided in the specific area. The specific area sensor 27 is a sensor that constantly monitors the passage of a sphere in the specific area. When the ball passes through the specific area, the specific area sensor 27 transmits a detection signal at that time to the special game control means 55. When the detection signal is received, the special game control means 55 determines that the continuation condition is satisfied.

Moreover, the upper limit continuous number of unit games is set in advance, and is 15 in this embodiment. The special game control means 55 permits the execution of the unit game again until the continuous number of unit games reaches 15, but when the continuous number of unit games reaches 15, the next time Control not to allow execution of unit games.
For this reason, the special game control means 55 includes means for counting the number of continuous executions of the unit game and storing the count value. For example, every time a unit game is started, the count value of the number of consecutive executions of the unit game is incremented by 1, and this count value is stored.

  When one unit game ends, the special game control means 55 determines whether or not the detection signal is transmitted from the specific area sensor 27 and the count value of the continuous execution count of the unit game reaches the upper limit continuous count. It is determined whether or not. When the special game control means 55 determines that the detection signal is transmitted from the specific area sensor 27 and the count value of the continuous execution count of the unit game has not reached the upper limit continuous count, the special game control means 55 repeats the unit game again. Allow execution. Thereby, the unit game is executed again.

  On the other hand, when it is determined that the detection signal is not transmitted from the specific area sensor 27, or when it is determined that the count value of the continuous execution count of the unit game has reached the upper limit continuous count, the special game The control means 55 is controlled so as not to execute the unit game again and to end the special game.

  The normal symbol start ball detecting means 56 detects when a ball passes through the normal symbol start port 14. The normal symbol start port 14 is provided with a normal symbol start port sensor 24 and is electrically connected to the normal symbol start ball detecting means 56.

  The normal symbol start port sensor 24 is a sensor that constantly monitors the passage of the ball of the normal symbol start port 14. When the ball passes through the normal symbol start port 14, the detection signal at that time is transmitted from the normal symbol start port sensor 24 to the normal symbol start ball detecting means 56. When this detection signal is received, the normal symbol start ball detecting means 56 detects that the ball has passed through the normal symbol start port 14.

The normal symbol lottery means 57 determines a symbol to be stopped and displayed on the normal symbol variation display device 34 by lottery on the condition that the ball of the normal symbol start port 14 passes.
The normal symbol lottery means 57 includes a hit determination random number generation means, a hit determination random number acquisition means, and a win determination means in the same manner as the win lottery means 52a described above.

  That is, the normal symbol lottery means 57 generates a hit determination random number having a predetermined period by a control program or the like, acquires a hit determination random number value when passing through the ball of the normal symbol start port 14, and determines the hit determination Based on the random number value, it is determined whether the winning or non-winning.

Further, the normal symbol lottery means 57 includes a stop symbol determining means for determining a symbol to be stopped and displayed on the normal symbol variation display device 34 based on the determination result as to whether the winning is or is not.
The normal symbol lottery means 57 determines “7” as the symbol to be stopped when the acquired random number for winning determination is determined to be winning. Further, the normal symbol lottery means 57 determines the symbol to be stopped and displayed as “5” or “6” when the acquired random number for winning determination is determined to be non-winning. Whether the symbol “5” or “6” is selected is determined by generating a stop symbol selection random number by the stop symbol selection random number generation means and by the stop symbol selection random number value acquisition means by 1 stop symbol selection random number. Get the numeric value. Next, a stop symbol (either “5” or “6”) corresponding to the acquired random number value for selecting a stop symbol is selected. The winning probability may be set to any value.

The normal symbol fluctuation control means 58 controls the normal symbol fluctuation display device 34 to display the fluctuation of the symbols on the basis of the lottery result of the normal symbol lottery means 57 when the ball passes through the normal symbol start port 14. Is.
The normal symbol variation control means 58 changes the symbol of the normal symbol variation display device 34 for a predetermined time, and finally stops the symbol determined by the normal symbol lottery means 57 on the normal symbol variation display device 34. .

  The enlargement member control means 59 controls the drive of the enlargement member 36 based on the lottery result of the normal symbol lottery means 57. Specifically, when the normal symbol lottery means 57 wins the lottery, the enlargement member 36 is driven and controlled. The timing of driving is immediately after the symbol of the normal symbol fluctuation display device 34 fluctuates for a predetermined time and the symbol determined by the normal symbol lottery means 57 is stopped and displayed on the normal symbol fluctuation display device 34.

  When the normal symbol lottery means 57 wins the lottery, the symbol “7” is finally stopped on the normal symbol variation display device 34. Immediately thereafter, the magnifying member control means 59 drives and controls the magnifying member 36 so as to enlarge the entrance of the symbol starting winning opening 11. This state is maintained for a certain period of time and then returned to the original position.

The bonus rate management means 60 calculates the bonus rate during the game, and further controls the bonus rate to be a predetermined reference value or less.
Here, the “act” in the present embodiment is provided for the purpose of facilitating winning, and operates under certain conditions. In the present embodiment, first, the winning combination is activated by a lottery performed by the normal symbol lottery means 57 and is activated when the winning symbol is stopped and displayed on the normal symbol variation display device 34. The entrance of the symbol starting winning opening 11 is enlarged, and the enlarged member control means 59 plays the role.

  Secondly, the winning operation is performed when the winning lottery means 52a is selected and the winning symbol is stopped and displayed on the symbol variation display device 31, and the special winning port 13 is operated by the special winning port driver 33. The special game control means 55 plays its role.

  Furthermore, the “actual rate” in this embodiment is based on the total number of payout balls (the balls won in any one of the winning openings (design starting winning opening 11, general winning opening 12, or special winning opening 13). The number of balls to be paid at the time of the actuating of the character (the number of balls to be paid out) (the symbol starting winning port 11 or the special when the entrance of the symbol starting winning port 11 or the special winning port 13 is opened or enlarged by the operation of the accessory) This is a value indicating the ratio of the number of balls paid out based on the number of balls won in the winning opening 13, and is calculated by “the rate of the bonus = the number of balls paid out during the operation of the bonus / the total number of balls paid out”. For example, when the total number of balls to be paid out is 1000 and the number of balls to be paid out during operation of the accessory is 700, the bonus rate is 700/1000 (= 0.7).

The accessory rate management means 60 includes the following payout ball number counting means 60a to measurement result initializing means 60h during operation of the accessory.
The number-of-payout ball counting means 60a at the time of actuating an object counts the number of balls to be dispensed at the time of actuating an action, which is paid out based on the operation of the accessory.
Specifically, when the special prize opening 13 is opened during the special game, a ball is awarded to the special prize opening 13 and the number of balls paid out based on the prize is the number of balls to be paid out during the operation of the accessory It is counted by the counting means 60a. When the special prize opening 13 is not open, such as during a normal game, the special prize opening 13 is closed, and the ball will not win.

In addition, when the entrance of the symbol start winning opening 11 is expanded by the expansion member 36, a ball is won in the symbol start winning opening 11, and the ball paid out based on the winning is when the accessory is activated. It is counted by the payout ball number counting means 60a. On the other hand, when the entrance of the symbol starting winning opening 11 is not enlarged by the expanding member 36, a ball is won in the symbol starting winning opening 11, and the ball paid out based on the winning is an accessory. It is not counted by the dispensed ball number counting means 60a during operation.
Furthermore, a ball won in the general winning opening 12, and a ball paid out based on the winning is not counted by the paying-out ball number counting means 60a at the time of the actuating operation.

  The total payout ball count means 60b counts the total number of payout balls paid out based on a ball won in any one of the winning openings (design starting winning opening 11, general winning opening 12 or special winning opening 13). Is. As a result, a payout ball that is not counted by the paying ball number counting means 60a when the accessory is actuated, that is, a ball is awarded to the symbol start winning port 11 when the entrance of the symbol start winning port 11 is not enlarged by the expanding member 36. The number of payout balls when the ball is won and the number of payout balls when the ball wins the general winning opening 12 are both counted by the total payout ball count means 60b.

  Here, in the present embodiment, the total payout ball number counting means 60b counts the number of payout balls based on the winning of balls to all winning ports. However, only the number of balls paid out without being based on the operation of the accessory is counted, and the number of balls obtained by adding this number of balls and the number of balls counted by the paying-out ball number counting means 60a during the operation of the accessory, The total payout ball count may be calculated.

  The accessory rate calculation means 60c is based on the number of balls paid out during the operation of the bonuses counted by the bonuses during the action of the bonuses and the total number of payout balls counted by the total payout balls count means 60b. The above-mentioned bonus rate is calculated. The bonus rate calculation means 60c is calculated every time the number of balls to be paid out when the bonus is activated and the total number of balls to be paid out are updated.

  In the present embodiment, the accessory rate calculation unit 60c calculates an accessory rate during a past fixed time (for example, the past one hour). For this reason, the accessory rate management means 60 includes a time measuring means 60d. The time measuring means 60d is composed of a timer or the like, and continues to measure time. Then, the accessory rate calculating unit 60c calculates the accessory rate based on the measurement result of the timing unit.

  The bonus rate information value storage means 60e includes a payout ball count at the time of actuating the bonuses counted by the bonus actuating action ball count means 60a, a total payout ball count counted by the total payout ball count means 60b, This is for storing the bonus rate calculated by the rate calculation means 60c. The stored number of balls to be paid out during operation of the accessory, the total number of balls to be paid out, and the bonus rate are sequentially updated each time they are counted or calculated.

  The accessory rate determining unit 60f determines whether or not the accessory rate calculated by the accessory rate calculating unit 60c exceeds a preset reference value. In the present embodiment, the reference value is set to 0.65. Then, it is determined whether or not the calculated bonus rate exceeds 0.65. For example, in the case where the calculated bonus rate is 0.66, it is determined that it exceeds the reference value of 0.65. Further, for example, when the calculated accessory rate is 0.60, it is determined that the reference value is not exceeded. This determination is performed every time the bonus rate is calculated by the bonus rate calculation means 60c.

The accessory rate control unit 60g controls the accessory rate to approach the reference value when the accessory rate determining unit 60f determines that the accessory rate exceeds the reference value.
The ball game machine 1 of this embodiment is controlled so that the bonus rate does not exceed 0.7. For this reason, in order to reduce an accessory rate when an accessory rate approaches 0.7, when an accessory rate exceeds 0.65, it controls to reduce an accessory rate.

  Here, in the present embodiment, firstly, the payout ball number fluctuation in which the payout ball number based on the winning is fluctuated to the first payout ball number or the second payout ball number different from the first payout ball number according to the bonus rate. A winning entrance is provided. In the present embodiment, the symbol starting winning port 11, the general winning port 12, and the special winning port 13 correspond to the payout ball number changing winning ports.

In the symbol starting winning opening 11, the expanding member 36 is driven by the operation of the accessory, and when the ball is won in the symbol starting winning opening 11 when the entrance of the symbol starting winning opening 11 is enlarged, the payout ball The number varies to 5 or 6 depending on the bonus rate. On the other hand, the number of balls to be paid out when the ball is won when the accessory is not in operation (when the entrance of the symbol starting winning opening 11 is not enlarged) is constant.
Further, the number of balls to be paid out at the time of winning a ball to the general winning opening 12 varies to 10 or 15 depending on the bonus rate.
Furthermore, the number of balls to be paid out at the time of winning a ball to the special winning opening 13 varies to 13 or 15 depending on the bonus rate.

  In the present embodiment, secondly, there is provided an opening-time variable prize winning opening in which the time that is opened or expanded by the operation of the accessory varies from the first time or the second time shorter than the first time. In the present embodiment, the symbol starting winning port 11 corresponds to the open equal time varying winning port. In the case where the entrance of the symbol starting winning opening 11 is expanded, the expanding time fluctuates to 0.2 seconds or 0.4 seconds depending on the bonus rate.

  When the bonus rate control means 60g determines that the bonus rate does not exceed the reference value by the bonus rate discrimination means 60f, the symbol start when the entrance of the symbol start winning port 11 is enlarged is shown. The number of balls to be paid out at the time of winning a ball to the winning prize opening 11 is set to six. On the other hand, when it is determined by the accessory rate determining means 60f that the accessory rate exceeds the reference value, the symbol starting winning port 11 when the entrance of the symbol starting winning port 11 is enlarged is shown. Set the number of balls to be paid out at the time of winning the ball to 5 to 5.

  In addition, when the bonus rate determining unit 60f determines that the bonus rate does not exceed the reference value, the bonus rate control unit 60g determines the number of balls to be paid out at the time of winning the ball to the general winning opening 12. Set to 10. On the other hand, when it is determined that the bonus rate exceeds the reference value by the bonus rate discriminating means 60f, the number of payout balls at the time of winning the ball to the general winning opening 12 is set to 15.

  Furthermore, when the bonus rate control means 60g determines that the bonus rate does not exceed the reference value by the bonus rate discrimination means 60f, the bonus rate control means 60g receives the ball at the special prize opening 13 during the special game. The number of balls to be paid out is set to 15. On the other hand, if it is determined by the bonus rate determining means 60f that the bonus rate exceeds the reference value, the number of balls to be paid out at the time of winning the ball to the special prize opening 13 during the special game is 13. Set to.

  Furthermore, when the bonus rate control means 60g determines that the bonus rate does not exceed the reference value by the bonus rate discrimination means 60f, the time during which the entrance of the symbol start winning port 11 is expanded ( The driving time of the magnifying member 36) is set to 0.4 seconds. On the other hand, when it is determined by the accessory rate determining means 60f that the accessory rate exceeds the reference value, the time for enlarging the entrance of the symbol start winning port 11 is set to 0.2 seconds. To do.

  Further, when the bonus rate determining unit 60f determines that the bonus rate does not exceed the reference value, the winning rate control means 60g determines the winning probability in the winning lottery means 52a as the first winning probability value described above. Set to (1/300). On the other hand, when the bonus rate determining means 60f determines that the bonus rate exceeds the reference value, the winning probability in the winning lottery means 52a is set to the above-described second winning probability value (1/400). Set.

  Furthermore, when the accessory rate determining unit 60f determines that the accessory rate does not exceed the reference value, the accessory rate controlling unit 60g performs the above-described first determination in the variation pattern lottery by the variation pattern lottery unit 52c. Control is performed so that one variation pattern is selected with a higher probability (with a selection rate A) than the second variation pattern. On the other hand, when it is determined by the accessory rate determining means 60f that the accessory rate exceeds the reference value, the variation pattern lottery by the variation pattern lottery means 52c changes the second variation pattern described above to the first variation. Control is performed such that selection is performed with a higher probability (with a selection rate B) than the pattern.

  As described above, when it is determined by the accessory rate determining means 60f that the accessory rate does not exceed the reference value, the payout ball number when the accessory is operating increases and the payout ball number when the accessory is not operated decreases. To be controlled. Further, the winning probability by the winning lottery means 52a is controlled to be high. Furthermore, control is performed so that the symbol variation display time is shortened on average. Thereby, it controls so that an accessory rate may become high.

On the other hand, when it is determined by the accessory rate determining means 60f that the accessory rate exceeds the reference value, the payout ball number when the accessory is activated decreases and the payout ball number when the accessory is inactive increases. To be controlled. Further, the winning probability by the winning lottery means 52a is controlled to be low. Furthermore, the control is performed so that the variable display time of the symbols becomes longer on average. Thereby, it controls so that an accessory rate may become low.
Therefore, the accessory rate is controlled to approach the reference value.

  The counting result initializing means 60h is for initializing the number of paying balls and the total number of paying balls stored in the accessory rate information value storage means 60e (erasing the counting results so far). . For example, when the time measured by the time measuring means 60d reaches 10 hours, the number of payout balls and the total payout balls stored so far are initialized.

  Further, an initialization switch 70 electrically connected to the counting result initialization means 60h is provided. When the initialization switch 70 is operated, the payout ball number and the total payout ball number during operation of the accessory stored in the accessory rate information value storage means 60e are forcibly initialized. For example, in the store where the ball game machine 1 is installed, when it is desired to initialize the payout ball number and the total payout ball number at the time of operating the accessory, the initialization switch 70 is operated so that it can be initialized. It is.

Subsequently, main processing in the present embodiment will be described based on a flowchart. FIG. 4 is a flowchart showing a management process of an accessory rate.
First, in step S1, it is determined whether or not a special game is being performed. If it is determined that the special game is not being performed, the process proceeds to step S2. When it is determined in step S1 that the special game is being played, the processing according to this flowchart is terminated. In other words, during the special game, the calculation of the bonus rate is not performed.

In step S2, the bonus rate calculation means 60c reads the total payout ball count counted by the total payout ball count counting means 60b and stored in the bonus rate information value storage means 60e. In the next step S3, the accessory rate calculation means 60c reads the number of paying balls during the operation of the accessory, which is counted by the payout ball number counting means 60a during the operation of the accessory and stored in the accessory rate information value storage means 60e.
Next, proceeding to step S4, the accessory rate calculating means 60c calculates an accessory rate from the total payout ball number and the payout ball number at the time of actuating operation read in step S2 and step S3, respectively.

  In the next step S5, the accessory rate determining means 60f determines whether or not the accessory rate calculated in step S4 exceeds 0.65 (reference value). When it is determined that the bonus rate exceeds 0.65, the processing from step S12 to step S17 is performed. On the other hand, when it is determined that the bonus rate does not exceed 0.65, the processing from step S6 to step S11 is performed.

  When the process proceeds from step S5 to step S6, the bonus rate control means 60g sets the number of payout balls of the general winning opening 12 to ten. In the next step S7, the number of payout balls of the symbol starting winning opening 11 at the time of actuating the accessory (when the expansion member 36 is driven) is set to six. In the next step S8, the number of payout balls of the special winning opening 13 is set to 15. Further, in the next step S9, the variation pattern selection rate of the variation pattern lottery means 52c is set to A. That is, as described above, the first variation pattern is selected with a higher probability than the second variation pattern.

  In the next step S10, the winning probability in the winning lottery means 52a is set to 1/300 (first winning probability value). Further, in the next step S11, the driving time of the expanding member 36, that is, the expanding time when the entrance of the symbol starting winning opening 11 is expanded is set to 0.4 seconds. Then, the process returns to step S1.

  On the other hand, when proceeding from step S5 to step S12, the bonus rate control means 60g sets the number of payout balls of the general winning opening 12 to 15. In the next step S13, the number of payout balls of the symbol starting winning opening 11 at the time of the actuating operation (when the expansion member 36 is driven) is set to five. In the next step S14, the number of payout balls of the special winning opening 13 is set to 13. Further, in the next step S15, the variation pattern selection rate of the variation pattern lottery means 52c is set to B. That is, as described above, the second variation pattern is selected with a higher probability than the first variation pattern.

  In the next step S16, the winning probability in the winning lottery means 52a is set to 1/400 (second winning probability value). Further, in the next step S17, the driving time of the expansion member 36, that is, the expansion time when the entrance of the symbol starting winning opening 11 is expanded is set to 0.2 seconds. Then, the process returns to step S1.

  FIG. 5 is a flowchart showing the symbol variation display process. First, in step S21, the game control means 50 continues to determine whether or not a ball has won a winning symbol 11 for starting the symbol. When a detection signal is transmitted from the start winning opening sensor 21 to the winning ball detecting means 51, the game control means 50 determines that a ball has won the symbol starting winning opening 11.

  If it is determined that a prize has been won, the process proceeds to step S22, and the prize ball payout control means 54 drives the prize ball payout device 32 to control the prize ball according to the bonus rate. That is, when winning the symbol starting winning slot 11 by the action of the winning combination, the winning ball payout control means 54 determines the number of winning balls set in step S7 or step S13 of FIG. 4 according to the winning combination rate. Control each to pay out. For example, when the bonus rate exceeds a reference value of 0.65, five prize balls are paid out.

  On the other hand, when the bonus rate does not exceed the reference value of 0.65, six prize balls are paid out. Further, when a ball wins the symbol starting winning slot 11 without being actuated by an accessory, the prize ball payout control means 54 pays out a predetermined number (for example, six) prize balls regardless of the bonus rate. To control. Note that the number of payout balls based on the ball that has won the symbol starting winning slot 11 may be changed according to the bonus rate as in the case of the general winning slot 12 without depending on the operation of the bonus.

  Next, proceeding to step S23, the winning lottery means 52a of the lottery means 52 obtains a winning determination random value and makes a winning determination. Here, the winning probability value varies depending on the bonus rate. As described above, when the current bonus rate does not exceed 0.65, the winning probability value is the value (1/300) set in step S10 of FIG. On the other hand, when the current bonus rate exceeds 0.65, the winning probability value is the value (1/400) set in step S16 of FIG.

  In the next step S24, the stop symbol lottery means 52b performs a lottery of a stop symbol based on the determination result of winning or non-winning. Further, in the next step S25, the variation pattern lottery means 52c performs a variation pattern lottery according to the bonus rate. As described above, when the current bonus rate does not exceed 0.65, the variation pattern is lottery based on the selection rate A set in step S9 of FIG. On the other hand, when the current bonus rate exceeds 0.65, a variation pattern lottery is performed based on the selection rate B set in step S15 of FIG.

In the next step S26, the symbol variation control means 53 performs symbol variation processing. That is, according to the variation pattern selected by the lottery, the variation display of the symbol displayed on the symbol variation display device 31 is performed, and the stop symbol selected by the lottery is finally stopped and displayed.
Next, the process proceeds to step S27, where it is determined whether or not the game is won. If the game is won, the process proceeds to step S28, and the special game control means 55 controls to shift to the special game. On the other hand, when it is determined that it is not winning, the processing according to this flowchart is terminated.

FIG. 6 is a flowchart showing main processing during a special game in the first embodiment. When the process shifts to the special game at step 28 in FIG. 5, the processing after step S31 in FIG. 6 is performed.
First, in step S31, the special game control means 55 starts a unit game. When the unit game is started, the process proceeds to step S32, and the special game control means 55 adds 1 to the continuous number R of unit games and stores it. Then, in the next step S33, the special game control means 55 drives the special winning opening driving device 33 to control the special winning opening 13 to be opened. Further, the special game control means 55 starts the measurement of the opening time of the special winning opening 13 by operating a timer.

  Next, proceeding to step S34, the winning ball detection means 51 determines whether or not there is a winning ball in the special winning opening 13. When a detection signal when a ball passes through the special winning opening sensor 23 is transmitted to the winning ball detecting means 51, it is determined that there is a winning of the ball at the special winning opening 13. When it is determined that there is a ball winning, the process proceeds to step S35, and when it is determined that there is no ball winning, the process proceeds to step S38.

  In step S35, the special game control means 55 adds 1 to the number N of winning balls to the special winning port 13 in the unit game. Then, the process proceeds to step S36, and the prize ball payout control means 54 drives the prize ball payout device 32 to perform control so as to pay out the prize ball according to the bonus rate. When the bonus rate immediately before the transition to the special game does not exceed 0.65, control is performed so as to pay out the number of prize balls (15) set in step S8 of FIG. On the other hand, when the bonus rate immediately before shifting to the special game exceeds 0.65, control is performed so as to pay out the number of winning balls (13) set in step S14 of FIG.

  Next, proceeding to step S37, the special game control means 55 determines whether or not the number N of winning balls to the special winning opening 13 is 10 or more. When it is determined that the number N of winning balls is 10 or more, it is determined that the unit game end condition is satisfied, and the process proceeds to step S39. On the other hand, when it is determined that the number N of winning balls is not 10 or more, the process proceeds to step S38. In step S38, the special game control means 55 determines whether or not the opening time of the special prize opening 13 has passed 30 seconds. If it is determined that 30 seconds have elapsed, it is determined that the end condition of the unit game is satisfied, and the process proceeds to step S39. On the other hand, when it is determined that 30 seconds have not elapsed, the process returns to step S34.

  When the unit game end condition is satisfied and the process proceeds to step S39, the special game control means 55 controls to end the unit game. That is, the special game control means 55 controls the special prize opening driving device 33 so as to close the special prize opening 13.

  When the bonus rate control means 60g determines that the bonus rate does not exceed the reference value by the bonus rate discrimination means 60f, the number of payout balls at the time of winning the ball to the general winning opening 12 is ten. Set to. On the other hand, when it is determined that the bonus rate exceeds the reference value by the bonus rate discriminating means 60f, the number of payout balls at the time of winning the ball to the general winning opening 12 is set to 15.

  Further, when the bonus rate determining means 60f determines that the bonus rate does not exceed the reference value, the bonus rate control means 60g determines the number of balls to be paid out at the time of winning the ball to the special winning opening 13. Set to 15. On the other hand, when it is determined by the bonus rate determining means 60f that the bonus rate exceeds the reference value, the number of payout balls at the time of winning a ball to the special winning opening 13 is set to 13.

  Furthermore, in the third embodiment, as in the first embodiment, the opening-time variation winnings in which the time that is opened or expanded by the operation of the accessory fluctuates to the first time or the second time shorter than the first time. Have a mouth. Here, the opening time variation winning opening is the first winning opening 17. In the case of expanding the entrance of the first winning port 17, the expanding time varies to 6 seconds (first time) or 5 seconds (second time) depending on the bonus rate.

  When the bonus rate control means 60g determines that the bonus rate does not exceed the reference value by the bonus rate discrimination means 60f, the bonus rate control means 60g enlarges the entrance of the first winning opening 17 (the symbol variation display device 31). When the winning symbol is stopped and displayed) is set to 6 seconds. On the other hand, when it is determined by the accessory rate determining means 60f that the accessory rate exceeds the reference value, the expanding time when the entrance of the first winning port 17 is expanded is 5 seconds. Set.

  Further, when the bonus rate determining means 60f determines that the bonus rate does not exceed the reference value, the winning rate determination means 60f determines the winning probability in the winning lottery means 52a as the first winning probability value (1 / 30). On the other hand, when it is determined by the bonus rate determining means 60f that the bonus rate exceeds the reference value, the winning probability in the winning lottery means 52a is set to a second winning probability value (lower than the first winning probability value ( 1/40).

  Furthermore, when the accessory rate determining unit 60f determines that the accessory rate does not exceed the reference value, the accessory rate controlling unit 60g performs the above-described first determination in the variation pattern lottery by the variation pattern lottery unit 52c. Control is performed so as to select one of the variation patterns from one variation pattern. On the other hand, when it is determined that the accessory rate exceeds the reference value by the accessory rate determining unit 60f, in the variation pattern lottery by the variation pattern lottery unit 52c, from among the second variation patterns described above, Control is performed to select one of the fluctuation patterns.

  Further, during the normal game, when the bonus rate determining means 60g determines that the bonus rate does not exceed the reference value by the bonus rate determining means 60f, the bonus rate control means 60g turns the ball guiding member 42 clockwise. The ball guiding device 41 is controlled so as to repeat one rotation counterclockwise after the rotation. On the other hand, when it is determined by the accessory rate determining means 60f that the accessory rate exceeds the reference value, the ball guiding member 42 is rotated clockwise once and then rotated counterclockwise three times. The ball guidance device 41 is controlled to repeat the above.

  Further, during the special game, the accessory rate control means 60g moves the ball guiding member 42 counterclockwise when it is determined by the accessory rate determination means 60f that the accessory rate does not exceed the reference value. The ball guidance device 41 is controlled to rotate. On the other hand, when it is determined by the accessory rate determining means 60f that the accessory rate exceeds the reference value, the sphere guiding device 41 is controlled to rotate the sphere guiding member 42 clockwise. .

  That is, during the normal game, when the bonus rate does not exceed the reference value, it becomes easy to shift to the special game because the ball is likely to win the third winning opening 18b. On the other hand, when the bonus rate exceeds the reference value, it becomes difficult for the ball to win the third winning opening 18b, so that it is difficult to shift to the special game.

  Further, during the special game, when the bonus rate does not exceed the reference value, the ball will not win the third prize opening 18b. Therefore, the special game can be performed by winning the ball into the third prize opening 18b. It will never end. On the other hand, when the bonus rate exceeds the reference value, the ball may win the third winning opening 18b, so that the special game is ended by winning the ball into the third winning opening 18b. It can happen.

  FIG. 17 is a flowchart showing a management process of an accessory rate in the third embodiment, and corresponds to FIG. 4 in the first embodiment. In the following flowchart, steps that perform the same processing as in the first embodiment are denoted by the same step numbers as in the first embodiment. Further, steps that perform similar processing are given step numbers obtained by adding “B” to the step numbers in the first embodiment. Hereinafter, a different part from 1st Embodiment is demonstrated, and the description about the part similar to 1st Embodiment is abbreviate | omitted.

When it is determined in step S5 of FIG. 17 that the accessory rate does not exceed the reference value of 0.65, the processing from step S6 to step S11B is performed. Since the process of step S6 and step S8 is the same as that of 1st Embodiment, description is abbreviate | omitted.
In step S7B, drive data A for the ball guidance device 41 is set. Here, “drive data A” means that during normal games, the ball guiding member 42 is rotated once in a clockwise direction and then rotated counterclockwise once, and during a special game, the ball guiding member 42 is repeated. This is drive data in which 42 is rotated counterclockwise.
In step S9B, the first variation pattern is set as the variation pattern to be selected.

  Furthermore, in step S10B, the winning probability value of the winning lottery means 52a is set to 1/30 which is the first winning probability value. Further, in step S11B, the driving time of the expansion member 36 (the time during which the entrance of the first winning port 17 is expanded) is set to 6 seconds.

On the other hand, when it is determined in step S5 that the accessory rate exceeds the reference value of 0.65, processing from step S12 to step S17B is performed. Since the process of step S12 and step S14 is the same as that of 1st Embodiment, description is abbreviate | omitted.
In step S13B, drive data B of the ball guidance device 41 is set. Here, “driving data B” means that during normal games, the ball guiding member 42 is rotated once in the clockwise direction and then rotated three times in the counterclockwise direction, and during the special game, the ball guiding member 42 is repeated. This is drive data in which 42 is rotated clockwise.
In step S15B, the second variation pattern is set as the variation pattern to be selected.

  Furthermore, in step S16B, the winning probability value of the winning lottery means 52a is set to 1/40 which is the second winning probability value. Furthermore, in step S17B, the driving time of the expansion member 36 (the time during which the entrance of the first winning port 17 is expanded) is set to 5 seconds.

FIG. 18 is a flowchart showing a symbol variation display process in the third embodiment, and corresponds to FIG. 5 in the first embodiment. Hereinafter, a different part from 1st Embodiment is demonstrated, and the description about the part similar to 1st Embodiment is abbreviate | omitted.
First, in step S21B, the game control means 50B continues to determine whether or not a ball has passed through the symbol start port 11B. When a detection signal is transmitted from the symbol winning opening sensor 21B to the symbol variation control means 53, the game control means 50B determines that the ball has passed through the symbol start opening 11B.

If it is determined that the ball has passed, the process proceeds to step S23. Note that unlike the first embodiment, a prize ball is not paid out by passing the ball of the symbol start port 11B, and therefore a process corresponding to step S22 of FIG. 5 is not provided.
Steps S23 and S24 are the same as those in the first embodiment. In the next step S25B, the variation pattern lottery means 52c performs a variation pattern lottery according to the bonus rate. As described above, when the current bonus rate does not exceed 0.65, a variation pattern lottery is performed from the first variation patterns set in step S9B of FIG. On the other hand, when the current bonus rate exceeds 0.65, a variation pattern lottery is performed from the second variation patterns set in step S15B of FIG.
The processes in the next step S26 and step S27 are the same as in the first embodiment. If it is determined that the game is won in step S27, the process proceeds to step S81. In step S <b> 81, the magnifying member control unit 59 drives the magnifying member 36 for a time corresponding to the bonus rate.

Here, when the current bonus rate does not exceed 0.65, the expansion member 36 is driven so as to expand the entrance of the first winning opening 17 for 6 seconds set in step S11B of FIG. .
On the other hand, when the current bonus rate exceeds 0.65, the expansion member 36 is driven so as to expand the entrance of the first winning opening 17 for 5 seconds set in step S17B of FIG. Therefore, the accessory rate control unit 60 g transmits information on the driving time of the expansion member 36 to the expansion member control unit 59. Then, the magnifying member control means 59 controls the driving of the magnifying member 36 while referring to the transmitted information relating to the driving time.

  Next, proceeding to step S82, the game control means 50B determines whether or not a ball has won the third winning opening 18b. When a ball wins the first winning port 17, the ball enters the ball support portion 42 a of the ball guiding member 42, and the ball is guided to the third winning port 18 b along the rotation of the ball guiding member 42. A ball enters the 3 winning opening 18b. When the detection signal is transmitted from the third winning hole sensor 29b to the winning ball detecting means 51, the game control means 50B determines that a ball has won the third winning hole 18b.

  When the ball wins the third winning opening 18b, the transition condition to the special game is satisfied, so that the process proceeds to step S28B and shifts to the special game. On the other hand, when the ball does not win the third winning port 18b, for example, when the ball does not enter the first winning port 17, the ball does not enter the ball support portion 42a of the ball guiding member 42. Or, when the ball has entered the ball support portion 42a of the ball guiding member 42, but the ball has won the second winning opening 18a, the process returns to step S21B without shifting to the special game.

  FIG. 19 is a flowchart showing main processing during a special game in the third embodiment, and corresponds to FIG. 6 in the first embodiment. When the process shifts to the special game at step 28B in FIG. 18, the process proceeds to step S91 in FIG. 19 to start the special game. Hereinafter, description of the same parts as those in the first embodiment will be omitted as appropriate.

  First, in step S91, the special game control means 55B continues to determine whether or not there is a winning of a ball to the special winning opening releasing winning opening 19. When a detection signal is transmitted from the special prize opening opening prize opening sensor 30 to the winning ball detection means 51, it is determined that a ball has won the special prize opening opening prize opening 19.

  If it is determined that the ball has won the special prize opening opening prize opening 19, the process proceeds to step S31, and the special game control means 55B starts a unit game. Then, in the next step S32B, the special game control means 55B adds 1 to the number X of winning balls X to the special winning opening opening winning opening 19, and proceeds to step S33. Hereinafter, step S33 to step S37 are the same as those in the first embodiment, and thus description thereof is omitted.

  In step S38B, the special game control means 55B determines whether or not the opening time of the special prize opening 13 has passed 10 seconds. If it is determined that 10 seconds have elapsed, it is determined that the end condition of the unit game is satisfied, and the process proceeds to step S39. On the other hand, when it is determined that 10 seconds have not elapsed, the process returns to step S34.

  When the unit game end condition is satisfied and the process proceeds to step S39, the special game control means 55B controls to end the unit game. That is, the special game control means 55B controls the special winning opening 13 to be driven and the special winning opening 13 to be closed.

  Next, proceeding to step S40B, the special game control means 55B determines whether or not the number X of winning balls X to the special winning opening releasing winning opening 19 has reached 16. When it is determined that the number has reached 16, the special game control means 55B determines that the continuation condition for the unit game is not satisfied, and controls to end the special game. On the other hand, if it is determined that the number X of winning balls to the special winning opening opening winning opening 19 has not reached 16, it is determined that the continuation condition of the unit game is satisfied, and the process returns to step S91. And control to execute the unit game again.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications such as the following are possible.
(1) In the present embodiment, the reference value of the accessory rate is set to 0.65, but the present invention is not limited to this, and may be set to any number.

(3) In the present embodiment, the example from the first embodiment to the third embodiment is given as an example of controlling the accessory rate to be close to the reference value by the accessory rate control means 60g. It is not something.
a) providing a payout ball variation winning opening, and varying the payout ball number based on the winning of the ball to the payout ball variation winning port according to the bonus rate (claim 2);
b) Varying the winning probability value of the winning lottery means 52a according to the bonus rate (claim 3),
c) A first variation pattern and a second variation pattern having different reference times from the start to the end of the symbol variation display are provided, and the selection rate of the first variation pattern and the second variation pattern according to the accessory rate (Claim 4),
d) Varying the time for opening or expanding the variable prize opening in accordance with the rate of bonuses (Claim 5);
e) providing a ball guidance device for controlling the guidance of the ball to the specific prize opening, and changing the guidance state of the ball to the specific prize opening by the ball guidance device according to the bonus rate (claim 6);
As long as at least one of them is provided and the accessory rate is controlled to be close to the reference value, it may be used.

  Furthermore, when a plurality of items a) to e) are provided, it is possible to control the accessory ratio to approach the reference value by executing at least one of them. For example, when the bonus rate slightly exceeds the reference value, one of the plurality determined by lottery or the like is executed, or when the bonus rate is further increased, a plurality is executed. In this way, it is possible to control the accessory ratio to approach the reference value.

  (4) In the present embodiment, control is performed so as to decrease the accessory ratio when the accessory ratio exceeds the reference value. However, it is also possible to control to increase the bonus rate when the bonus rate falls below a specific value. In this case, for example, by increasing the number of balls to be paid out when a ball wins the special winning opening 13 by a method opposite to the method shown in this embodiment, the number of balls to be paid up to that time is increased. Is mentioned.

  (5) In the first embodiment, for example, when a specific winning symbol (an odd number symbol such as “777”) is stopped and displayed on the symbol variation display device 31 and a special game is started, The game may be set to a game state (probability variation state) in which the winning probability is higher than that in the normal game. In this case, the winning determination random number value acquired by the winning lottery means 52a of the lottery means 52 is selected as a random value for selecting a winning symbol that shifts to the probability variation state, and a winning symbol that does not shift to the probability variation state. In addition to the method of pre-assigning the random number value to be selected, whether or not to select the winning symbol that shifts to the probability variation state after the determination of winning or whether to select the winning symbol that does not shift to the probability variation state A method of determining by lottery or the like can be considered.

In the above case, only when the game is shifted to the probability fluctuation state game, it may be determined by the accessory rate determining unit 60f and the accessory rate controlling unit 60g may control the accessory rate. That is, in a game that is not in a probability fluctuation state, the bonus rate may not be controlled by the bonus rate control means 60g.
In this way, the bonus rate can be controlled only when the probability variation state in which the payout rate increases.

  (6) In the first embodiment, the special area sensor 27 and the special prize opening sensor 23 are provided separately, and the ball that has won the special prize opening 13 always passes the specific area sensor 27 and the special prize opening sensor 23 is always provided. To pass. However, the present invention is not limited to this, and the ball may pass through only one of the specific area sensor 27 and the special prize opening sensor 23, and the specific area sensor 27 may also serve as the special prize opening sensor 23. That is, when the ball has passed through the specific area sensor 27, a detection signal indicating that the ball has passed through the specific area sensor 27 is transmitted to the special game control means 55, and also indicates that the ball has won the specific winning opening 13. The detection signal may be transmitted to the winning ball detection means 51. In this way, the balls that have passed through the specific area sensor 27 can be counted as winning balls in the special winning opening 13.
