  The present invention relates to a ball game machine having a variable winning opening, wherein when a predetermined condition is satisfied, a variable winning opening is opened or enlarged by activating a role item to facilitate winning of a ball. It relates to a gaming machine.

  Conventionally, as a ball game machine for adjusting the payout ratio, for example, a ball game machine described in Japanese Patent Application Laid-Open No. H11-4942 is known. In this ball game machine, the number of game balls (the number of fired balls) fired into the game area by the player and the number of awarded balls paid out are stored, and based on these stored contents, The drive of the variable winning opening is controlled. By controlling in this way, the payout rate (the number of paid-out prize balls with respect to the number of fired balls) can be made to converge to a predetermined value, thereby preventing a variation in the prize-winning rate of each ball game machine. be able to.

However, in the above-described conventional technology, there is a problem that even if it is possible to adjust the payout rate, the adjustment cannot be performed for the accessory of the ball game machine.
Here, as a type of the ball game machine, first, a ball game machine provided with a symbol variation display device is known. In this ball game machine, a lottery is performed when a ball wins the symbol start winning port, and the symbol of the symbol variation display device is changed based on the lottery result. When a lottery is won, a specific symbol is stopped and displayed, and the game is shifted to a special game.
During a special game, a special winning prize mouth is opened by operating a role item under a certain condition. Thereby, during the special game, many balls win in the special winning opening, so that the player can obtain many prize balls.

  Secondly, under certain conditions, the special winning opening is opened and closed by the operation of the accessory, and when a predetermined condition is satisfied, the ball is shifted to a special game in which the special winning opening is repeatedly opened and closed. Gaming machines are known. In this ball game, when the special winning opening is continuously opened and closed, many balls win in the special winning opening, so that the player can acquire many winning balls as described above.

  As described above, the prize balls obtained by the ball game machine include the prize balls obtained by the operation of the accessory and the prize balls obtained when the player wins the general winning opening regardless of the operation of the accessory. It is roughly divided into. Here, the duty ratio, which represents the ratio of the number of prize balls paid out by the operation of the role to the total number of prize balls paid out, is an important factor in managing the ball-out of a ball game machine. However, according to the conventional technology, it was not possible to adjust the accessory ratio.

  The property ratio of the ball-and-ball game machine is designed to converge to an appropriate value. However, as described above, when a lottery is won, the game is shifted to a special game, and the special game is activated and the special winning opening is opened. Therefore, there is a problem that variation occurs. In addition, even in a ball-and-ball game machine that shifts to a special game in which the special winning opening is repeatedly opened and closed when a predetermined condition is satisfied, a difference occurs in the ease of shifting to the special game due to a variation in adjustment of the game nail and the like. Therefore, also in this case, a variation occurs in the accessory ratio.

  Therefore, a problem to be solved by the present invention is to make it possible to accurately control payouts by allowing the accessory ratio to converge to an appropriate value.

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 tray 4 is for storing the lent or dispensed balls and for supplying the launch device 6 with balls to be launched into the game area 8. When the upper tray 4 is filled with a predetermined amount of balls, the dispensed balls are sent to the lower tray 5.
The launching device 6 is provided on the right side of the lower tray 5, and a portion operated by the player is formed in a handle shape. A player fires a ball by operating the handle-shaped portion. The ball fired by the firing 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 port 11, a general winning port 12, and a special winning port 13.
Here, in the present embodiment, a variable winning opening and a general winning opening are provided as a winning opening for paying out a prize ball based on a winning of a ball.
The "variable winning opening" is a winning opening in which the accessory is activated when a predetermined condition is satisfied, and the entrance is opened or expanded.
On the other hand, the “general winning opening” is a winning opening (a winning opening unrelated to the operation of the role) in which the entrance is not opened or enlarged and the size of the entrance is fixed.
In the present embodiment, a symbol starting winning port 11 and a special winning port 13 are provided as variable winning ports. Further, a general winning opening 12 is provided as a general winning opening.

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

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

The general winning opening 12 is a winning opening for paying out a predetermined number of balls to a player every time a ball is won.
Furthermore, the special winning opening 13 is a relatively large winning opening that is not opened during a normal game but is opened only during a special game. 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. Then, when shifting to this special game, the special winning opening 13 is opened.

A symbol variation display device 31 is provided substantially at the center of the game area 8.
The symbol variation display device 31 performs image display including symbol variation display on a liquid crystal display or a dot display. When the ball wins the symbol opening winning opening 11, an image including a symbol (for example, a character, a graphic, 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 starting winning opening 11, and is provided integrally with the symbol starting winning opening 11 at the entrance of the symbol starting winning opening 11. The expansion member 36 is provided with a pair of symmetric 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, for example, the size of a ball.
On the other hand, the enlarged member 36 shown by a solid line shows a state in which the symmetrical member is spread outward and the entrance of the symbol starting winning opening 11 is enlarged. When the enlarging member 36 is arranged as shown by the solid line, it becomes easier for the sphere to win the symbol starting winning opening 11.

  Further, on the left and right sides of the symbol variation display device 31, ordinary symbol starting ports 14 are provided. Ordinarily, the symbol starting port 14 is formed so that the ball simply passes and the passed ball is detected. The prize balls are not paid out even when passing through the normal symbol starting port 14. When the passage of the ball through the normal symbol starting port 14 is detected, it is determined in the bullet game machine 1 whether or not the entrance of the symbol starting winning port 11 is to be enlarged.

Further, below the special winning opening 13, a normal symbol change display device 34 is provided.
The normal symbol variation display device 34 is for performing variable display (rotation display and stop display) of the symbol based on the detection of the passage of the ball of the ordinary symbol starting port 14. As described above, when the passage of the ball through the normal symbol starting port 14 is detected, whether or not to enlarge the entrance of the symbol starting winning port 11 is determined by lottery, and the lottery result is displayed.

In the present embodiment, the normal symbol fluctuation display device 34 displays symbols (numerals) in seven segments, and displays the lottery result as one of “5”, “6”, or “7” at the time of stop display. Display a symbol. When the symbol “5” or “6” is stopped and displayed, it indicates that the lottery is not won as a result of the lottery. When the symbol “7” is stopped and displayed, it means that the symbol is won as a result of the lottery. Show.
When the symbol “7” is stopped and displayed, the magnifying member 36 is driven by the operation of the accessory, and the entrance of the symbol starting winning opening 11 is enlarged for a certain time. After that, it is returned to the original state again.

When the normal symbol variation display device 34 is displaying the symbol variation when the ball passes through the ordinary symbol starting 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).
Then, when the change of the symbol by the ordinary symbol change display device 34 can be started, if the reserved ball is stored, the variation display of the symbol based on the reserved ball is started.

Subsequently, control of the ball game machine 1 in the present embodiment will be described. FIG. 3 is a block diagram illustrating functions of the ball game machine 1 according to the first embodiment, and mainly illustrates a portion according to the present invention.
The game control means 50 is a means for integrally controlling the entire ball game machine 1 including the progress and effects of the game. The game control means 50 includes a CPU for performing calculations and the like, a ROM for storing programs necessary for the progress of the game, data for effects, and the like, and data and the like fetched when the CPU performs various controls. And a RAM for temporarily storing the data.

The game control means 50 includes the following means. In addition, each means shown below mainly shows a part related to the present embodiment, and is not limited to the illustrated means.
The winning ball detecting means 51 detects when a ball has won the symbol starting winning opening 11, the general winning opening 12, and the special winning opening 13. Each of the symbol starting 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. It is electrically connected to the means 51.

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

  Similarly, the general winning opening sensor 22 and the special winning opening sensor 23 are provided at an entrance portion of the general winning opening 12 and a predetermined position of the special winning opening 13, respectively, and a ball to the general winning opening 12 and the special winning opening 13 is provided. It is a sensor that constantly monitors winning. When the ball wins the general winning opening 12 or the special winning opening 13, the ball passes through the general winning opening sensor 22 or the special winning opening sensor 23, respectively. As a result, the detection signal at that time is transmitted to the winning ball detecting means 51 from the general winning opening sensor 22 or the special winning opening sensor 23, respectively. When this detection signal is received, the winning ball detecting means 51 detects that the ball has won the general winning opening 12 or the special winning opening 13, respectively. Note that 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 performs a lottery of a winning or a non-winning, a lottery of a stop symbol, and a lottery of a variation pattern on condition that the winning ball detecting means 51 detects the winning of a ball to the winning opening 11 for symbol starting. Is what you do.
First, the lottery means 52 includes a lottery means 52a for performing a lottery of winning or non-winning. The winning lottery means 52a determines, for example, whether there is a winning based on a random number generating means (soft random number or the like), a random number obtaining means for obtaining a random number generated by the random number generating means, and a random number value obtained by the random number obtaining means. Determining means for performing the determination.

  The random number generation means generates a random number having a predetermined cycle (a random number for winning determination) by a control program or the like. The random number acquiring means acquires the random number generated by the random number generating means at a predetermined time, in the present embodiment, when the winning ball detecting means 51 detects that a ball has won the symbol starting winning opening 11. The determining means determines whether the random number value obtained by the random number obtaining means is a winning or a non-winning. Among the random numbers of a predetermined cycle generated by the random number generation means, the random number value of the winning is predetermined. Then, if the random number value obtained by the random number obtaining means matches the random number value of the winning, it is determined that the game has been won, and if not, it is determined that the game has not been won.

In the present embodiment, the winning probability value in the lottery of the winning lottery means 52a is the first winning probability value (1/300 in the present embodiment) and the second winning probability value (the present embodiment) lower than the first winning probability value. In the embodiment, 1/400). For example, a plurality of random numbers for winning when set to the first winning probability value are determined, and the number of random numbers for winning when set to the second winning probability value is determined by the first winning probability value. May be set to be smaller than the number of winning random numbers when set to.
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 is provided with a stop symbol lottery means 52b for randomly selecting a stop symbol to be stopped and displayed on the symbol variation display device 31 based on the result of the determination of winning or non-winning. When it is determined that the winning symbol has been won, the stopped symbol lottery means 52b selects the winning symbol as the stopped symbol. On the other hand, when it is determined that the winning symbol has not been won, the stopped symbol lottery means 52b selects a non-winning symbol as the stopped symbol.

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

  As the lottery of the stop symbol by the stop symbol lottery means 52b, in the same manner as the hit lottery means 52a, a random number for stop symbol selection is generated using soft random numbers, and any one random number value is obtained, and the random number value is obtained. Is selected.

  Thirdly, the lottery means 52 includes a variation pattern lottery means 52c for randomly selecting a variation pattern during the variation display of the symbol 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 a variation pattern storage unit of the present invention) 52d. In the lottery of the variation pattern, a random number for variation pattern selection is generated by using a soft random number by the same method as the winning lottery means 52a, any one random number value is obtained, and the variation pattern corresponding to the random number value is varied. Selection from the pattern data table 52d is an example.

In the present embodiment, at the start of the variable display of the symbols, all of the three numbers such as left, middle, and right are variably displayed, and then stop-displayed in the order of left, middle, and right. Stop displaying numbers etc.
At this time, when the left numeral or the like among the three numerals or the like is the same as the middle numeral or the like, control is performed so as to display that the vehicle is in the reach state. Here, the reach state is a state in which when the right numeral or the like matches the left or middle numeral or the like, the state becomes a winning symbol, and means a state having a possibility of becoming a winning symbol.

  For example, when the selected stop symbol is a winning symbol such as “333” or “777”, or when the left and middle numerals or the like are the same as “330” or “778”, the symbol is a non-winning symbol. In some cases, the left and middle numbers and the like are stopped, and the right numbers and the like are variably displayed to indicate that the vehicle is in the reach state. Then, when such a stop symbol is selected, a variation pattern for displaying that the vehicle is in the reach state is selected. This variation pattern is provided in advance with a plurality of variation patterns having different degrees of reliability that are finally stopped and displayed in the winning symbol. For example, a low-probability variation pattern having a low probability of being stopped and displayed in a winning symbol and a high-probability variation pattern having a high probability of being stopped and displayed in a winning symbol may be provided.

In this case, when the winning symbol is selected by the stop symbol lottery means 52b, the fluctuation pattern lottery means 52c selects the high probability fluctuation pattern with a higher probability than the low probability fluctuation pattern.
On the other hand, when the non-winning symbol is selected by the stop symbol lottery means 52b, the fluctuation pattern lottery means 52c selects the low probability fluctuation pattern with a higher probability than the high probability fluctuation 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 is longer than the first time. It is roughly divided into a plurality of second fluctuation patterns set for 2 hours (for example, 8 seconds). The selectivity of the first variation pattern and the second variation pattern will be described later.

The symbol variation control unit 53 controls the symbol variation display device 31 to perform symbol variation display on condition that the winning ball detection unit 51 detects the winning of a ball in the symbol starting winning opening 11. Things.
The symbol variation control means 53 performs symbol variation display and stop display by the symbol variation display device 31 based on the lottery result of the lottery means 52. That is, the symbol variation control means 53 controls the symbol variation display according to the variation pattern selected by the variation pattern lottery means 52c, and finally stops and displays the stop symbol selected by the stop symbol lottery means 52b. I do.

The prize ball payout control means 54 controls driving of the prize ball payout device 32 for paying out prize balls. As described above, when the winning ball detecting means 51 receives the detection signals from the starting 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. Thus, the prize ball payout device 32 is controlled. When driven, the prize ball payout device 32 pays out prize balls to the upper tray 4 or the lower tray 5 of the ball game machine 1.
Further, in the present embodiment, the number of payout balls of the symbol starting winning opening 11, the general winning opening 12, and the special winning opening 13 varies, which will be described later.

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

The special game control means 55 first 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 winning opening drive device 33 to open the special winning opening 13.
In addition, “until the predetermined condition is satisfied” means that the number of the balls that have won the special winning opening 13 has reached a specified number (10 in the present embodiment), or the opening time of the special winning opening 13 has been a predetermined time ( In the present embodiment, either one of 30 seconds has elapsed.

For this reason, the special game control means 55 determines whether or not a predetermined condition is satisfied, in order to determine whether or not the special winning opening 13 during the unit game, winning ball number counting means, the special winning opening 13 Open time measuring means for measuring the open time of the device.
As described above, when a ball wins in the special winning opening 13, the ball 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. Upon receiving this detection signal, the winning ball detecting means 51 detects that the ball has won the special winning opening 13. Then, every time the winning ball detecting means 51 detects the winning of a ball in the special winning opening 13, the winning ball counting means increments the count value by one and stores it.

  The opening time measuring means measures the time from when the unit game is started and the special winning opening 13 is opened, and has, for example, a timer. When the unit game is started and the special winning opening 13 is opened by the special winning opening driving device 33, the timer is operated to start measuring 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 specified number or when the time measured by the opening time measuring means reaches a predetermined time. At this time, it is determined that the above-described predetermined condition is satisfied, and the drive of the special winning opening drive device 33 is controlled to close the special winning opening 13 and control to end the unit game.

  In addition, when the continuation condition is satisfied in the unit game, the special game control unit 55 controls so as to execute the unit game again within a range of the upper limit continuous number of unit games. That is, 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 continuous unit games is not exceeded.

Here, a specific area (not shown) is provided in the special winning opening 13 in advance, and when passing through the 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 passage of a sphere in a specific area. When the ball passes through the specific area, the detection signal at that time is transmitted from the specific area sensor 27 to the special game control means 55. Upon receiving this detection signal, the special game control means 55 determines that the continuation condition is satisfied.

The upper limit continuous number of unit games is set in advance, and is 15 in the present embodiment. Then, the special game control means 55 permits the execution of the unit game again until the number of continuous unit games reaches 15 times, but when the number of continuous unit games reaches 15 times, Control is performed so that execution of the unit game is not permitted.
For this reason, the special game control means 55 includes means for counting the number of continuous executions of the unit game and storing this count value. For example, each time a unit game is started, the count value of the number of continuous executions of the unit game is incremented by one, and this count value is stored.

  Then, when one unit game is completed, the special game control means 55 determines whether or not a detection signal is transmitted from the specific area sensor 27 and the count value of the number of continuous executions of the unit game reaches the upper limit number of continuous games. Is determined. If the special game control means 55 determines that the detection signal has been transmitted from the specific area sensor 27 and that the count value of the number of continuous executions of the unit game has not reached the upper limit number of continuous times, the special game control means 55 executes 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 number of consecutive executions of the unit game has reached the upper limit number of consecutive games, the special game The control means 55 controls so as not to execute the unit game again and to end the special game.

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

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

The ordinary symbol lottery means 57 determines a symbol to be stopped and displayed on the ordinary symbol variation display device 34 by lottery on condition that the ball of the ordinary symbol starting port 14 passes.
The normal symbol lottery means 57 includes a hit determination random number generating means, a hit determination random number value obtaining means, and a hit determination means, like the hit lottery means 52a described above.

  That is, the ordinary symbol lottery means 57 generates a random number for collision determination having a predetermined cycle by a control program or the like, acquires a random number for collision determination when the ball of the ordinary symbol starting port 14 passes, and obtains a random number for collision determination. Based on the random number value, it is determined whether the winning or non-winning.

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

The ordinary symbol variation control means 58 controls the ordinary symbol variation display device 34 to perform symbol variation display based on the lottery result of the ordinary symbol lottery means 57 when the ball passes through the ordinary symbol starting port 14. Things.
After changing the symbol of the ordinary symbol variation display device 34 for a predetermined time, the ordinary symbol variation control means 58 finally stops the symbol determined by the ordinary symbol lottery means 57 on the ordinary 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 ordinary symbol lottery means 57. Specifically, when the normal symbol lottery means 57 wins the lottery, the enlargement member 36 is drive-controlled. The drive is performed immediately after the symbol of the ordinary symbol fluctuation display device 34 fluctuates for a predetermined time and the symbol determined by the ordinary symbol lottery means 57 is stopped and displayed on the ordinary symbol fluctuation display device 34.

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

The accessory ratio management means 60 calculates the accessory ratio during the game, and further controls the accessory ratio to be equal to or less than a predetermined reference value.
Here, the “accessories” in the present embodiment are provided for the purpose of facilitating winning, and operate under certain conditions. In the present embodiment, firstly, the winning item is won by lottery by the ordinary symbol lottery means 57, and is activated when the winning symbol is stopped and displayed on the ordinary symbol variation display device 34. The entrance of the symbol starting winning opening 11 is enlarged, and the expanding member control means 59 plays a role.

  Secondly, it is activated when the winning lottery means 52a wins the lottery and the winning symbol is stopped and displayed on the symbol variation display device 31. And the special game control means 55 plays the role.

  Furthermore, the “principal property ratio” in the present embodiment is based on the total number of payout balls (balls that have won one of the winning openings (symbol winning opening 11, the general winning opening 12 or the special winning opening 13). The number of paid-out balls at the time of the operation of the role relative to the number of paid-out balls (when the entrance of the symbol starting prize opening 11 or the special prize opening 13 is opened or enlarged by the operation of the accessory, the symbol starting prize opening 11 or special). This is a value indicating the ratio of the number of balls paid out based on the balls that have won the winning opening 13), and is calculated by "the bonus rate = the number of paid-out balls at the time of operating the bonus / the total number of paid-out balls". For example, when the total number of payout balls is 1000 and the number of payout balls at the time of operating the accessory is 700, the accessory ratio is 700/1000 (= 0.7).

The accessory ratio management means 60 includes the following accessory actuation payout ball number counting means 60a to measurement result initialization means 60h.
The number-of-paid-balls counting means 60a counts the number of paid-out balls at the time of actuation of the accessory, which is paid out based on the operation of the accessory.
Specifically, when the special winning opening 13 is opened during the special game, a ball wins in the special winning opening 13 and the ball paid out based on the winning is the number of balls to be paid out when the accessory is activated. It is counted by the counting means 60a. When the special winning opening 13 is not opened, such as during a normal game, the ball does not win since the special winning opening 13 is closed.

Further, when the entrance of the symbol starting winning opening 11 is enlarged by the expanding member 36, a ball wins in the symbol starting winning opening 11, and the ball paid out based on the winning is used when the character 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 wins in the symbol starting winning opening 11, and the ball paid out based on the winning is a character It is not counted by the number-of-payout-balls counting means 60a at the time of operation.
Furthermore, a ball wins in the general winning opening 12, and the ball paid out based on the winning is not counted by the number-of-payout-balls counting means 60a when the accessory is activated.

  The total payout ball number counting means 60b counts the total payout ball number paid out based on the ball that has won one of the winning openings (symbol winning start opening 11, general winning opening 12, or special winning opening 13). Things. As a result, the payout balls not counted by the number-of-payout-balls counting means 60a when the accessory is activated, that is, when the entrance of the symbol starting winning opening 11 is not enlarged by the expanding member 36, the ball wins in the symbol starting winning opening 11. The number of payout balls when the ball has been paid and the number of payout balls when the ball has won the general winning opening 12 are both counted by the total payout ball number counting 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 based on the operation of the accessory is counted, and the number of the balls and the number of balls counted by the number-of-activities-paid-out ball counting means 60a are summed up by the number of balls. The total number of payout balls may be calculated.

  The duty ratio calculating means 60c is based on the number of paid-out balls counted by the duty actuated ball counting means 60a and the total number of paid-out balls counted by the total paid-out ball number counting means 60b. This is to calculate the above-mentioned accessory ratio. The bonus ratio calculation means 60c is calculated each time the number of balls to be paid out at the time of the activation of the accessory and the total number of balls to be paid out are updated.

  Further, in the present embodiment, the accessory ratio calculating means 60c calculates an accessory ratio in a certain past time (for example, one hour in the past). For this reason, the accessory ratio management means 60 includes a time counting means 60d. The time measuring means 60d is composed of a timer or the like, and keeps measuring time. Then, the accessory ratio calculating means 60c calculates the accessory ratio based on the measurement result of the timing unit.

  The accessory ratio information value storage means 60e stores the number of paid-out balls counted by the accessory actuation ball counting means 60a, the total number of paid-out balls counted by the total paid-out ball number counting means 60b, and This is for storing the accessory ratio calculated by the physical ratio calculation means 60c. The stored number of payout balls at the time of operating the accessory, the total number of payout balls, and the accessory ratio are sequentially updated each time they are counted or calculated.

  The accessory ratio determining means 60f determines whether or not the accessory ratio calculated by the accessory ratio calculating means 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 ratio exceeds 0.65. For example, when the calculated bonus ratio is 0.66, it is determined that the calculated ratio exceeds the reference value of 0.65. In addition, for example, if the calculated bonus ratio is 0.60, it is determined that the ratio does not exceed the reference value. This determination is performed every time the accessory ratio is calculated by the accessory ratio calculating means 60c.

The accessory ratio control unit 60g controls the accessory ratio to approach the reference value when the accessory ratio determination unit 60f determines that the accessory ratio exceeds the reference value.
The ball game machine 1 of the present embodiment is controlled so that the accessory ratio does not exceed 0.7. For this reason, when the accessory ratio approaches 0.7, the accessory ratio is reduced. When the accessory ratio exceeds 0.65, control is performed so as to decrease the accessory ratio.

  Here, in the present embodiment, first, the payout ball number fluctuation in which the payout ball number based on the prize fluctuates to the first payout ball number or the second payout ball number different from the first payout ball number in accordance with the accessory ratio. Provide a winning opening. In the present embodiment, the payout number variable winning opening corresponds to a symbol starting winning opening 11, a general winning opening 12, and a special winning opening 13.

In the symbol starting winning opening 11, the magnifying member 36 is driven by the operation of the accessory, and a payout ball when a ball wins in the symbol starting winning opening 11 when the entrance of the symbol starting winning opening 11 is enlarged. The number fluctuates to five or six depending on the accessory ratio. On the other hand, the number of payout balls when a ball is won when the accessory is not operated (when the entrance of the symbol starting winning port 11 is not enlarged) is constant.
In addition, the number of balls to be paid out at the time of winning a ball into the general winning opening 12 varies to 10 or 15 in accordance with the bonus ratio.
Furthermore, the number of payout balls at the time of winning a ball into the special winning opening 13 varies to 13 or 15 in accordance with the bonus ratio.

  Further, in the present embodiment, secondly, there is provided an opening and other time varying winning opening in which the time that is opened or expanded by the operation of the accessory changes to the first time or the second time shorter than the first time. In this embodiment, a winning opening 11 for symbol start corresponds to the opening-time fluctuation winning opening. In the case of enlarging the entrance of the symbol starting winning opening 11, the enlarging time fluctuates to 0.2 seconds or 0.4 seconds depending on the bonus ratio.

  When the accessory ratio is determined not to exceed the reference value by the accessory ratio determining means 60f, the symbol rate controlling means 60g starts the symbol starting when the entrance of the symbol starting winning opening 11 is enlarged. The number of payout balls at the time of winning a ball to the winning opening 11 is set to six. On the other hand, when the bonus ratio is determined to exceed the reference value by the bonus ratio determining means 60f, the symbol starting winning opening 11 when the entrance of the symbol starting winning opening 11 is expanded. The number of payout balls at the time of winning the ball is set to five.

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

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

  Further, when the accessory ratio is determined not to exceed the reference value by the accessory ratio determination unit 60f, the accessory ratio control unit 60g is enlarging the entrance of the symbol starting winning opening 11 ( The driving time of the enlarging member 36) is set to 0.4 seconds. On the other hand, when it is determined by the bonus material ratio determining means 60f that the bonus material ratio exceeds the reference value, the time for enlarging the entrance of the symbol starting winning opening 11 is set to 0.2 seconds. I do.

  When the accessory ratio is determined not to exceed the reference value by the accessory ratio determining unit 60f, the accessory ratio controlling unit 60g determines the winning probability in the winning lottery unit 52a by the first winning probability value described above. (1/300) is set. 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 changed to the above-described second winning probability value (1/400). Set.

  Furthermore, the bonus material rate control means 60g, when the bonus material rate determination means 60f determines that the bonus material rate does not exceed the reference value, in the variation pattern lottery by the variation pattern lottery means 52c, the second Control is performed such that one variation pattern is selected with a higher probability (with a selectivity A) than the second variation pattern. On the other hand, when the accessory ratio is determined to be greater than the reference value by the accessory ratio determining means 60f, the second variation pattern is changed to the first variation in the variation pattern lottery by the variation pattern lottery means 52c. Control is performed so that selection is made with a higher probability than the pattern (with the selectivity B).

  As described above, when the accessory ratio is determined not to exceed the reference value by the accessory ratio determination means 60f, the number of payout balls when the accessory is activated increases and the number of payout balls when the accessory is not activated decreases. Is controlled as follows. In addition, the winning lottery means 52a is controlled so that the winning probability is increased. Furthermore, control is performed such that the symbol variable display time is shortened on average. Thereby, the control is performed so that the accessory ratio is increased.

On the other hand, when the accessory ratio determining means 60f determines that the accessory ratio exceeds the reference value, the number of balls to be paid out when the accessory is activated decreases and the number of balls to be paid out when the accessory is not activated increases. Is controlled to In addition, the winning lottery means 52a is controlled so that the winning probability is reduced. Furthermore, control is performed such that the variable display time of the symbol becomes longer on average. Thereby, the control is performed so that the accessory ratio is reduced.
Therefore, the accessory ratio is controlled so as to approach the reference value.

  The counting result initializing means 60h is for initializing the number of payout balls and the total number of payout balls when the accessory is activated, stored in the accessory ratio information value storing means 60e (erasing the counting result up to that time). . For example, when the time measured by the time counting means 60d reaches 10 hours, the number of payout balls and the total number of payout balls at the time of the actor's operation stored up to that time are initialized.

  An initialization switch 70 electrically connected to the counting result initialization means 60h is provided. When the initialization switch 70 is operated, the number of paid-out balls and the total number of paid-out balls when the accessory is activated, which is stored in the accessory ratio information value storage means 60e, is forcibly initialized. For example, when it is desired to initialize the number of paid-out balls and the total number of paid-out balls when the accessory is operated at the store where the ball game machine 1 is installed, the initialization switch 70 is operated to enable the initialization. It is.

Subsequently, main processing in the present embodiment will be described based on a flowchart. FIG. 4 is a flowchart illustrating the management process of the accessory ratio.
First, in step S1, it is determined whether or not a special game is being played, and if it is determined that a special game is not being played, the process proceeds to step S2. When it is determined in step S1 that a special game is being played, the processing according to this flowchart ends. That is, during the special game, the calculation of the accessory ratio is not performed.

In step S2, the accessory ratio calculating means 60c reads the total number of payout balls counted by the total payout ball number counting means 60b and stored in the accessory ratio information value storage means 60e. In the next step S3, the accessory ratio calculating means 60c reads the number of payout balls at the time of the actuation of the accessory, which is counted by the number-of-activities-when-activated payout ball counting means 60a and stored in the accessory material ratio information value storage means 60e.
Next, proceeding to step S4, the accessory ratio calculating means 60c calculates the accessory ratio from the total number of payout balls and the number of payout balls at the time of the operation of the accessory, which are read in step S2 and step S3, respectively.

  In the next step S5, the accessory ratio determining means 60f determines whether or not the accessory ratio calculated in step S4 exceeds 0.65 (reference value). When it is determined that the accessory ratio exceeds 0.65, the processing from step S12 to step S17 is performed. On the other hand, when it is determined that the accessory ratio 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 accessory ratio 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 when the accessory is activated (when the enlarging 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 selectivity of the fluctuation pattern of the fluctuation 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 enlarging member 36, that is, the enlarging time when enlarging the entrance of the symbol starting winning opening 11 is set to 0.4 seconds. Then, the process returns to step S1.

  On the other hand, when the process proceeds from step S5 to step S12, the accessory ratio control means 60g sets the number of payout balls of the general winning opening 12 to 15 pieces. In the next step S13, the number of payout balls of the symbol starting winning opening 11 when the accessory is activated (when the expanding 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 selectivity of the fluctuation pattern of the fluctuation 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 enlarging member 36, that is, the enlarging time when enlarging the entrance of the symbol starting winning opening 11 is set to 0.2 seconds. Then, the process returns to step S1.

  FIG. 5 is a flowchart showing a symbol change display process. First, in step S21, the game control means 50 continues to determine whether or not a ball has won the symbol starting winning port 11. 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 the ball has won the symbol starting winning opening 11.

  When it is determined that a winning has been achieved, the process proceeds to step S22, and the prize ball payout control unit 54 drives the prize ball payout device 32 to control so as to pay out a prize ball according to the winning percentage. That is, when a winning is achieved in the symbol starting winning opening 11 by the operation of the accessory, the prize ball payout control means 54 determines the number of prize balls set in step S7 or step S13 in FIG. Control to pay out each. For example, when the accessory ratio exceeds the reference value of 0.65, five prize balls are paid out.

  On the other hand, when the accessory ratio does not exceed the reference value of 0.65, six prize balls are paid out. Also, when a ball wins in the symbol starting winning opening 11 without operating the accessory, the award ball payout control means 54 pays out a fixed number (for example, 6) of award balls regardless of the bonus rate. Control. In addition, the number of payout balls based on the balls that have won the symbol starting winning opening 11 without depending on the operation of the accessory may also be changed according to the winning rate, similarly to the general winning opening 12.

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

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

In the next step S26, the symbol variation control means 53 performs symbol variation processing. That is, in accordance with the variation pattern selected by the lottery, the symbol displayed on the symbol variation display device 31 is displayed in a variable manner, 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 winning is achieved. If the winning is achieved, the process proceeds to step S28, and the special game control means 55 controls to shift to the special game. On the other hand, if it is determined that the winning has not been won, the processing according to this flowchart ends.

FIG. 6 is a flowchart showing main processing during a special game in the first embodiment. When the game is shifted to the special game in step 28 of 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, in which the special game control unit 55 adds 1 to the number of continuous unit games R and stores it. Then, in the next step S33, the special game control means 55 controls the special winning opening driving device 33 to open the special winning opening 13. In addition, the special game control means 55 operates a timer to start measuring the opening time of the special winning opening 13.

  Next, proceeding to step S34, the winning ball detection means 51 determines whether or not there is a winning of a 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 in 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 opening 13 in the unit game. Then, the process proceeds to step S36, in which the prize ball payout control means 54 controls the prize ball payout device 32 to pay out a prize ball according to the winning ratio. When the bonus rate immediately before shifting 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 in 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 prize 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 of winning balls N to the special winning opening 13 is 10 or more. When it is determined that the winning ball number N 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 winning opening 13 has passed 30 seconds. When it is determined that 30 seconds have elapsed, it is determined that the termination condition of the unit game has been 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 condition for ending the unit game 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 winning opening drive device 33 to control the special winning opening 13 to be closed.

  Next, proceeding to step S40, the special game control means 55 determines whether or not the number of continuous unit games R has reached 15 which is the upper limit number of continuous games. When it is determined that the continuous number R has reached 15 times, the special game control means 55 determines that the continuation condition of the unit game is not satisfied, and controls to end the special game. On the other hand, when it is determined that the continuous number R has not reached 15 times, the process proceeds to step S41. In step S41, the special game control means 55 determines whether or not a ball has passed a specific area in the special winning opening 13 during the unit game.

  During the unit game, when a ball detection signal is transmitted from the specific area sensor 27 to the special game control means 55, it is determined that the ball has passed the specific area sensor 27, and the special game control means 55 Is determined to be satisfied, and the process returns to step S31 to control the unit game to be executed again. On the other hand, when it is determined that the ball has not passed through the specific area sensor 27, the special game control means 55 determines that the continuation condition of the unit game is not satisfied, and performs control to end the special game.

FIG. 7 is a flowchart showing the flow of processing when a ball passes through the ordinary symbol starting port 14.
In FIG. 7, when the ball passes through the ordinary symbol starting port 14 and the detection signal transmitted at this time is received by the ordinary symbol starting ball detecting means 56, the processing according to this flowchart is started, and the process proceeds to step S51. In step S51, the ordinary symbol lottery means 57 acquires a random number for hit determination and a random number for symbol selection for stop.

  In the next step S52, the ordinary symbol variation control means 58 controls the ordinary symbol variation display device 34 to perform symbol variation display. More specifically, the normal symbol lottery means 57 determines whether the winning or non-winning is performed based on the random number for hit determination acquired in step S51, and sets the stopped symbol to " 7 ". When it is determined that the winning symbol is not won, the stop symbol is determined to be "5" or "6" based on the random number value for selecting the stop symbol. Then, the normal symbol variation control means 58 controls to perform variation display of the symbol and to stop and display the determined stop symbol.

  When the normal symbol is stopped and displayed, the process proceeds to step S53, where it is determined whether or not the winning has been achieved. If it is determined that the winning has not been won, the processing according to the present flowchart ends. On the other hand, when the winning is achieved, the process proceeds to step S54, and the enlarging member control means 59 controls the enlarging member 36 to be driven. Here, when the current bonus rate does not exceed 0.65, the enlarging member is expanded so as to enlarge the entrance of the symbol starting winning opening 11 for 0.4 seconds set in step S11 of FIG. 36 is controlled.

  On the other hand, when the current accessory ratio exceeds 0.65, the enlargement is performed so that the entrance of the symbol starting winning opening 11 is enlarged for 0.2 seconds set in step S17 of FIG. The driving of the member 36 is controlled. For this reason, the accessory ratio control means 60 g transmits information on the drive time of the enlargement member 36 to the enlargement member control means 59. The enlargement member control means 59 controls the driving of the enlargement member 36 while referring to the transmitted information on the drive time. Then, the processing according to this flowchart ends.

FIG. 8 is a flowchart showing a process when a ball is won to a general winning opening.
First, in step S61, the game control means 50 continues to determine whether or not a ball has won the general winning opening 12. When a detection signal is transmitted from the general winning opening sensor 22 to the winning ball detecting unit 51, the game control unit 50 determines that a ball has won the general winning opening 12.

  If it is determined that a prize has been won, the process proceeds to step S62, and the prize ball payout control means 54 drives the prize ball payout device 32 and controls so as to pay out a prize ball. Here, when the current bonus ratio does not exceed the reference value of 0.65, control is performed so as to pay out the number of prize balls (ten) set in step S6 in FIG. On the other hand, when the current bonus rate exceeds the reference value of 0.65, control is performed so as to pay out the number of prize balls (15) set in step S12 in FIG. Thereafter, the process returns to step S61.

  Note that the above processing shows the processing at the time of winning the ball into the general winning opening 12, but the processing at the time of winning the ball into the winning opening 11 for symbol starting is performed in steps S21 to S22 in FIG. It is as shown by. The processing at the time of winning a ball into the special winning opening 13 is as shown in steps S34 to S36 in FIG.

(2nd Embodiment)
Subsequently, a second embodiment of the present invention will be described. In the second embodiment, portions having the same functions as those in the first embodiment are denoted by the same reference numerals, and overlapping description will be omitted as appropriate. Further, those having functions corresponding to the functions of the first embodiment are denoted by “A”.
FIG. 9 is a front view showing the game board 2A of the second embodiment. FIG. 10 is a front view showing the special winning opening 13 of FIG. 9 in an enlarged manner. In the ball game machine 1A of the second embodiment, the symbol variation display device 31 is not provided unlike the ball game machine 1 of the first embodiment. For this reason, the symbol starting winning port 11 and the like are not provided.

  In the second embodiment, the special winning opening 13 is provided substantially at the center of the game area 8. Further, as shown in FIG. 10, an opening and closing member 38 for opening and closing the special winning opening 13 is provided. The opening / closing member 38 is normally arranged at a position shown by a broken line, and closes the special winning opening 13. However, under a certain condition, the opening / closing member 38 is opened to a position shown by a solid line in FIG. (Middle, arrow direction) a predetermined number of times.

Further, in the game area 8, in addition to the general winning port 12, special winning port starting ports 15 and 16 are provided. The special winning opening 15 and 16 are respectively arranged below the special winning opening 13. The special winning opening 15 and 16 are a winning opening for paying out a predetermined number of balls to the player and opening and closing the special winning opening 13 every time a ball is won.
The special winning opening 15 is a winning opening for opening and closing the special winning opening 13 once, and the special winning opening starting opening 16 is a winning opening for opening and closing the special winning opening 13 twice.

  Further, in the special winning opening 13, a specific region V is formed as shown in FIG. When a ball wins in the special winning opening 15 or 16 and the special winning opening 13 is opened or closed once or twice, the ball enters the special winning opening 13 and the ball further occupies the specific area V. When passing, the condition for shifting to the special game is satisfied, and the game shifts to the special game.

  In the special game, a unit game in which the special winning opening 13 is opened / closed by the opening / closing member 38 is executed. During this unit game, when at least one of the balls that have won the special winning opening 13 passes through the specific area V, the unit game is repeated within the upper limit number of consecutive times as in the first embodiment. Be executed.

Further, as shown in FIG. 10, an enlargement member 40 is provided in the specific region V. The enlargement member 40 is for enlarging the specific region V according to the accessory ratio. In FIG. 10, when the enlarging member 40 is arranged at the position indicated by the solid line, the entrance of the specific region V is slightly larger than the diameter of the sphere. On the other hand, when the enlarging member 40 is arranged at the position indicated by the dotted line in the drawing, the entrance of the specific region V is enlarged, and the sphere easily enters the specific region V.
The driving of the enlargement member 40 is performed by a specific region enlargement device 40 described later.

  Here, the bonus in the second embodiment is a special winning opening 13 which is opened and closed by the opening and closing member 38 when the special winning opening 15 or 16 is won or when a special game is played. The special winning opening opening / closing control means 61 described later plays this role.

FIG. 11 is a block diagram illustrating functions of a ball game machine 1A according to the second embodiment, and mainly illustrates a portion according to the present invention. Hereinafter, points different from the first embodiment will be mainly described.
The special winning port starting ports 15 and 16 are provided with starting port sensors 25 and 26, respectively, and are electrically connected to the winning ball detecting means 51.

  The starting port sensors 25 and 26 are sensors provided at the entrance portions of the special winning port starting ports 15 and 16, respectively, and constantly monitor the winning of a ball into the special winning port starting ports 15 and 16. When the ball wins the special winning opening 15 or 16, the ball passes through the opening sensor 25 or 26, respectively. Thereby, the detection signal at that time is transmitted to the winning ball detection means 51 from the starting port sensor 25 or 26, respectively. Upon receiving this detection signal, the winning ball detecting means 51 detects that the ball has won the special winning opening 15 or 16 respectively.

  The special winning opening opening / closing control means 61 controls an opening / closing member driving device 37 for driving the opening / closing member 38. When the winning prize ball detecting means 51 detects that the ball has won the special prize opening start port 15 or 16, the special prize opening control means 61 controls the opening and closing member driving device 37 to drive the opening and closing member 38, The special winning opening 13 is opened and closed. The special winning opening opening / closing control means 61 opens and closes the special winning opening 13 once when a ball wins in the special winning opening starting opening 15, and when the ball wins in the special winning opening starting opening 16, the special winning opening. The opening and closing of the mouth 13 is controlled to be performed twice.

The specific area sensor 27 is a sensor that detects that a ball has passed through a specific area V provided in the special winning opening 13. When the ball passes through the specific area V, a detection signal from the specific area sensor 27 is transmitted to the special game control means 55A.
Upon receiving this detection signal during the normal game, the special game control means 55A determines that the condition for shifting to the special game is satisfied, and performs control to start the special game.

When the special game is started, the unit game is executed as in the first embodiment.
In the second embodiment, the special game control means 55A drives the opening / closing member 38 by controlling the opening / closing member drive device 37 by the special winning opening opening / closing control means 61. One unit game is performed until the special winning opening 13 is opened and closed 18 times or 10 balls are won in the special winning opening 13.

  For this reason, the special game control means 55A counts the number of times the special winning opening 13 is opened and closed and also counts the number of winning balls in the special winning opening 13 in the unit game during the unit game of the special game. When the counted number of times of opening and closing reaches 18 times, or when the counted number of winning balls in the special winning opening 13 becomes 10 or more, the special game control means 55A sets the end condition of the unit game. Is determined to be satisfied, and control is performed so as to end the unit game. As a result, the special winning opening opening / closing control means 61 controls the opening / closing member driving device 37 to stop the operation of the opening / closing member 38 and to close the special winning opening 13.

  The special game control means 55A determines whether or not the detection signal from the specific area sensor 27 has been transmitted (whether or not the ball has passed the specific area V) during the unit game. It is determined that the continuation condition of the game is satisfied, and the unit game is executed again on condition that the number does not exceed the upper limit continuous number (15 times as in the first embodiment).

  Further, in the second embodiment, similarly to the first embodiment, the payout ball number fluctuation winning opening in which the payout ball number based on the winning changes to the first payout ball number or the second payout ball number different from the first payout ball number. Is provided. In the second embodiment, the payout-ball-number-variation winning prize port is a general prize port 12, a special prize port 13, and special prize port starting ports 15 and 16.

The number of balls to be paid out at the time of winning a ball to the general winning opening 12 and the special winning opening starting openings 15 and 16 fluctuates to ten or fifteen in accordance with a winning combination.
In addition, the number of balls to be paid out when a ball is awarded to the special winning opening 13 varies to 13 or 15 in accordance with the bonus ratio.

  When the accessory ratio determining means 60f determines that the accessory ratio does not exceed the reference value, the accessory ratio controlling means 60g controls the ball to the general winning opening 12 and the special winning opening start openings 15 and 16. The number of payout balls at the time of winning is set to ten. On the other hand, if the bonus material ratio determining means 60f determines that the bonus material ratio exceeds the reference value, the general winning opening 12 and the special winning opening start ports 15 and 16 when the ball is awarded. The number of payout balls is set to 15.

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

  Further, when the accessory ratio is determined not to exceed the reference value by the accessory ratio determining unit 60f, the accessory ratio controlling unit 60g controls the driving of the enlarging member 40 by the specific area enlarging device 39 and specifies the Control is performed so that the entrance of the region V is enlarged (the enlarged member 40 is arranged at the position shown by the broken line in FIG. 10). On the other hand, when the accessory ratio is determined by the accessory ratio determining unit 60f to be greater than the reference value, the accessory ratio controlling unit 60g controls the driving of the enlarging member 40 by the specific area enlarging device 39. Is controlled so that the entrance of the specific region V is not enlarged (the enlarged member 40 is arranged at the position shown by the solid line in FIG. 10).

In addition, the number-of-payout-balls counting means 60a counts the number of payout balls at the time of the operation of the accessory, which is paid out based on the operation of the accessory, as in the first embodiment. Here, in the second embodiment, during a normal game or a special game, when the special winning opening 13 is opened and closed by the opening / closing member 38, a ball wins in the special winning opening 13 and a payment is made based on the winning. The dispensed balls are counted by the number-of-dispensed-balls counting means 60a when the accessory is activated. Also, in any of the normal game and the special game, when the special winning opening 13 is not opened and closed, the special winning opening 13 is closed, so that the ball does not win.
Furthermore, the ball that has won the general winning opening 12 and the ball that has been paid out based on the winning is not counted by the number-of-payout-operating-balls counting means 60a as in the first embodiment.

  Subsequently, main processing in the second embodiment will be described based on a flowchart. FIG. 12 is a flowchart showing the management process of the accessory ratio, which corresponds to FIG. 4 of the first embodiment. In the following flowcharts, steps for performing the same processing as in the first embodiment are assigned the same step numbers as in the first embodiment. Also, steps for performing similar processing are given the step numbers obtained by adding “A” to the step numbers of the first embodiment. Hereinafter, portions different from the first embodiment will be described, and description of the same portions as the first embodiment will be omitted.

When it is determined in step S5 in FIG. 12 that the accessory ratio does not exceed 0.65, the processing in steps S6, S7A, S8, and S11A is performed. Here, the processing of steps S9 and S10 shown in the first embodiment is not performed.
In step S7A, the number of payout balls of the special winning opening starting port 15 or 16 is set to 10. In step S11A, the enlarging member 40 is set at the enlarging position (a position at which the entrance of the specific region V is enlarged).

On the other hand, when it is determined in step S5 that the accessory ratio exceeds 0.65, the processing in steps S12, S13A, S14, and S17A is performed. Here, the processing of steps S15 and S16 shown in the first embodiment is not performed.
In step S13A, the number of payout balls of the special winning opening starting port 15 or 16 is set to 15. In step S17A, the enlargement member 40 is set to the normal position (a position where the entrance of the specific region V is not enlarged).

FIG. 13 is a flowchart showing main processing during a normal game in the second embodiment, and corresponds to FIG. 5 of the first embodiment.
First, in step S71, the game control means 50A continues to determine whether or not a ball has won the special winning opening 15 or 16. When a detection signal is transmitted from the starting port sensor 25 or 26 to the winning ball detecting means 51, the game control means 50A determines that a ball has won the special winning port starting port 15 or 16.

  If it is determined that a prize has been won, the process proceeds to step S72, in which the prize ball payout control means 54 drives the prize ball payout device 32 to control so as to pay out a prize ball. Here, the prize ball payout control means 54 controls to pay out the currently set number of prize balls according to the bonus rate. For example, when the accessory ratio exceeds the reference value of 0.65, 15 prize balls set in step S13A of FIG. 12 are paid out. On the other hand, when the accessory ratio does not exceed the reference value of 0.65, ten prize balls set in step S7A of FIG. 12 are paid out.

  Next, proceeding to step S73, the special winning opening opening / closing control means 61 controls the opening / closing member driving device 37 to open and close the special winning opening 13. As described above, the special winning opening 13 is opened and closed once when a ball wins the special winning opening 15 and twice when a ball wins in the special winning opening 16.

  In the next step S74, it is determined whether or not a ball has won the special winning opening 13. When the detection signal from the special winning opening sensor 23 is transmitted to the winning ball detecting means 51, it is determined that the ball has won the special winning opening 13, and the process proceeds to step S75. On the other hand, when it is determined that the ball has not won the special winning opening 13, the process returns to step S71.

  In step S75, the prize ball payout control means 54 controls the prize ball payout device 32 to pay out prize balls. Here, the prize ball payout control means 54 controls to pay out the currently set number of prize balls according to the bonus rate. For example, when the accessory ratio exceeds the reference value of 0.65, the thirteen prize balls set in step S14 of FIG. 12 are paid out. On the other hand, when the accessory ratio does not exceed the reference value of 0.65, 15 prize balls set in step S8 of FIG. 12 are paid out. Then, the process proceeds to step S76.

  In the step S76, it is determined whether or not the ball has passed the specific area V of the special winning opening 13. When the detection signal from the specific area sensor 27 is transmitted to the special game control means 55A, it is determined that the ball has passed the specific area V of the special winning opening 13, and the special game control means 55A proceeds to step S77. , And control is made to shift to a special game. On the other hand, when it is determined that the sphere does not pass through the specific area V, the process returns to step S71.

FIG. 14 is a flowchart showing main processing of a special game in the second embodiment, and corresponds to FIG. 6 in the first embodiment.
When the process shifts to the special game in step S77 in FIG. 13, the processing after step S31 in FIG. 14 is performed.

In step S33A, the special winning opening opening / closing control means 61 controls the opening / closing member driving device 37 to drive the opening / closing member 38 and start opening and closing the special winning opening 13. Then, the process proceeds to step S34.

  The processing from step S34 to step S37 is the same as in the first embodiment, and a description thereof will be omitted. In step S38A, the special game control means 55A determines whether the number of times of opening and closing the special winning opening 13 has reached 18 times. When it is determined that the game has reached 18 times, it is determined that the condition for terminating the unit game is satisfied, and the process proceeds to step S39A. On the other hand, when it is determined that the number has not reached 18 times, the process returns to step S34.

  In step S39A, the special game control means 55A controls to end the unit game. That is, the special winning opening opening / closing control means 61 controls the opening / closing member driving device 37 to stop the driving of the opening / closing member 38, and ends the opening and closing of the special winning opening 13. At this time, the opening / closing member 38 is stopped at a position where the special winning opening 13 is closed. Then, the process proceeds to step S40. The processing after step S40 is the same as in the first embodiment, and a description thereof will be omitted.

In the second embodiment, since the ordinary symbol starting port 14 and the like are not provided unlike the first embodiment, the processing shown in FIG. 7 of the first embodiment is not performed.

The symbol starting port sensor 21B is a sensor that detects that a ball has passed through the symbol starting port 11B. Even if the ball passes through the symbol starting port 11B, the prize ball is not paid out.
When the ball passes through the symbol starting port 11B, a detection signal at that time is transmitted from the symbol starting port sensor 21B to the symbol variation control means 53.

  The first winning opening 17 is provided with a first winning opening sensor 28. The first winning opening sensor 28 is a sensor for detecting that a ball has won the first winning opening 17, and is electrically connected to the winning ball detecting means 51. When a ball wins in the first winning opening 17, a detection signal at that time is transmitted from the first winning opening sensor 28 to the winning ball detecting means 51.

  Similarly, the second winning opening 18a and the third winning opening 18b are provided with a second winning opening sensor 29a and a third winning opening sensor 29b, respectively. The second winning opening sensor 29a and the third winning opening sensor 29b are sensors for detecting that a ball has won the second winning opening 18a and the third winning opening 18b, respectively, and are electrically connected to the winning ball detecting means 51. Have been. When a ball wins in the second winning opening 18a or the third winning opening 18b, a detection signal at that time is transmitted to the winning ball detecting means 51 from the second winning opening sensor 29a or the third winning opening sensor 29b, respectively.

Further, the winning opening 19 for opening a special winning opening is provided with a winning opening sensor 30 for opening a special winning opening. The winning opening sensor 30 for opening a special winning opening is a sensor for detecting that a ball has won the winning opening 19 for opening a special winning opening, and is electrically connected to the winning ball detecting means 51. When a ball wins in the special winning opening opening winning opening 19, a detection signal at that time is transmitted from the special winning opening opening winning opening sensor 30 to the winning ball detecting means 51.
The ball guiding device 41 is for rotating the ball guiding member 42 described above, and includes a motor and the like. The ball guiding device 41 is electrically connected to the accessory ratio management unit 60B, and is controlled by the accessory ratio management unit 60B.

In the third embodiment, similarly to the first embodiment, the number of payout balls based on a prize changes to the first payout ball number or the second payout ball number different from the first payout ball number, and the payout ball number fluctuation winning prize. Have a mouth. Here, the payout number variation winning prize port in the third embodiment is a general prize port 12 and a special prize port 13.
The number of payout balls at the time of winning a ball into the general winning opening 12 varies to 10 or 15 in accordance with the bonus rate.
In addition, the number of balls to be paid out when a ball is awarded to the special winning opening 13 varies to 13 or 15 in accordance with the bonus ratio.

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

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

  Furthermore, in the third embodiment, similarly to the first embodiment, the opening and other time fluctuation prize in which the time that is opened or expanded by the operation of the accessory changes to the first time or the second time shorter than the first time. Have a mouth. Here, the opening winning time variation winning opening is the first winning opening 17. In the case where the entrance of the first winning opening 17 is expanded, the expanding time fluctuates to 6 seconds (first time) or 5 seconds (second time) in accordance with the bonus ratio.

  When the accessory ratio is determined not to exceed the reference value by the accessory ratio determining unit 60f, the accessory ratio control unit 60g enlarges the entrance of the first winning opening 17 (the symbol variation display device 31). Is set to 6 seconds when the winning symbol is stopped and displayed. On the other hand, if the bonus ratio is determined to exceed the reference value by the bonus ratio determining means 60f, the time for expanding the entrance of the first winning opening 17 is set to 5 seconds. Set.

  In addition, when the accessory ratio determining unit 60f determines that the accessory ratio does not exceed the reference value, the accessory ratio controlling unit 60g determines the winning probability in the winning lottery unit 52a as the first winning probability value (1). / 30). On the other hand, when it is determined by the bonus material ratio determining means 60f that the bonus material rate exceeds the reference value, the winning probability in the winning lottery means 52a is changed to a second winning probability value (lower than the first winning probability value). 1/40).

  Furthermore, the bonus material rate control means 60g, when the bonus material rate determination means 60f determines that the bonus material rate does not exceed the reference value, in the variation pattern lottery by the variation pattern lottery means 52c, the second Control is performed so as to select one of the fluctuation patterns from one fluctuation pattern. On the other hand, when the accessory ratio is determined to exceed the reference value by the accessory ratio determining means 60f, in the variation pattern lottery by the variation pattern lottery means 52c, from among the second variation patterns described above, Control is performed to select one of the variation patterns.

  Further, during the normal game, if the accessory ratio determining means 60f determines that the accessory ratio does not exceed the reference value, the accessory ratio controlling means 60g rotates the ball guiding member 42 clockwise by one. The ball guiding device 41 is controlled so as to repeat one rotation counterclockwise after the rotation. On the other hand, when the accessory ratio is determined by the accessory ratio determining means 60f to be greater than the reference value, the ball guiding member 42 is rotated once clockwise and then three times counterclockwise. The ball guiding device 41 is controlled so that is repeated.

  Also, during the special game, the bonus material rate control means 60g rotates the ball guiding member 42 counterclockwise when the bonus material rate determination means 60f determines that the bonus material rate does not exceed the reference value. The ball guiding device 41 is controlled to rotate. On the other hand, when the accessory ratio is determined to exceed the reference value by the accessory ratio determining means 60f, the ball guiding device 41 is controlled to rotate the ball guiding member 42 clockwise. .

  That is, during the normal game, when the accessory ratio does not exceed the reference value, the ball can easily enter the third winning opening 18b, so that the transition to the special game is facilitated. On the other hand, when the accessory ratio exceeds the reference value, it is difficult for the ball to enter 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 does not win in the third winning opening 18b, so that the special game is played by the winning of the ball in the third winning opening 18b. It does not end. On the other hand, when the bonus ratio exceeds the reference value, a ball may be won in the third winning opening 18b, and the special game is ended by the winning of the ball in the third winning opening 18b. It is possible.

  FIG. 17 is a flowchart showing the management process of the accessory ratio in the third embodiment, and corresponds to FIG. 4 in the first embodiment. In the following flowcharts, steps for performing the same processing as in the first embodiment are assigned the same step numbers as in the first embodiment. In addition, steps that perform similar processing are given the step numbers obtained by adding “B” to the step numbers of the first embodiment. Hereinafter, portions different from the first embodiment will be described, and description of the same portions as the first embodiment will be omitted.

When it is determined in step S5 in FIG. 17 that the accessory ratio does not exceed the reference value of 0.65, the processing from step S6 to step S11B is performed. Steps S6 and S8 are the same as in the first embodiment, and a description thereof will not be repeated.
In step S7B, the driving data A of the ball guiding device 41 is set. Here, the “drive data A” means that during the normal game, the ball guiding member 42 is repeatedly rotated once clockwise and then counterclockwise once, and during the special game, the ball guiding member 42 is repeatedly rotated. 42 is drive data for rotating the counterclockwise 42.
In step S9B, the first variation pattern is set as the variation pattern to be selected.

  Further, 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 drive time of the enlargement member 36 (the time during which the entrance of the first winning opening 17 is enlarged) is set to 6 seconds.

On the other hand, when it is determined in step S5 that the accessory ratio exceeds the reference value of 0.65, the processing from step S12 to step S17B is performed. Steps S12 and S14 are the same as in the first embodiment, and a description thereof will not be repeated.
In step S13B, the driving data B of the ball guiding device 41 is set. Here, the “drive data B” means that during the normal game, the ball guiding member 42 is repeatedly rotated once clockwise and then three times counterclockwise, and during the special game, the ball guiding member 42 is repeatedly rotated. 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.

  Further, 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. Further, in step S17B, the drive time of the enlargement member 36 (the time during which the entrance of the first winning opening 17 is enlarged) is set to 5 seconds.

FIG. 18 is a flowchart showing a symbol change display process according to the third embodiment, and corresponds to FIG. 5 of the first embodiment. Hereinafter, portions different from the first embodiment will be described, and description of the same portions as the first embodiment will be omitted.
First, in step S21B, the game control means 50B continues to determine whether or not a ball has passed through the symbol starting port 11B. When a detection signal is transmitted from the symbol winning opening sensor 21B to the symbol variation control unit 53, the game control unit 50B determines that the ball has passed through the symbol starting port 11B.

If it is determined that the ball has passed, the process proceeds to step S23. Unlike the first embodiment, since a prize ball is not paid out by passing the ball through the symbol starting port 11B, a process corresponding to step S22 in FIG. 5 is not provided.
Steps S23 and S24 are the same as those in the first embodiment. In the next step S25B, the fluctuation pattern lottery means 52c performs a lottery selection of the fluctuation pattern according to the accessory ratio. As described above, when the current accessory ratio does not exceed 0.65, the lottery of the variation pattern 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 lottery of a variation pattern is performed from the second variation patterns set in step S15B of FIG.
The processing in the next steps S26 and S27 is the same as in the first embodiment. If it is determined in step S27 that the winning has occurred, the process proceeds to step S81. In step S81, the enlargement member control unit 59 drives the enlargement member 36 for a time corresponding to the accessory ratio.

Here, when the current bonus ratio does not exceed 0.65, the enlarging member 36 is driven so as to enlarge the entrance of the first winning opening 17 for 6 seconds set in step S11B of FIG. .
On the other hand, when the current material ratio exceeds 0.65, the enlarging member 36 is driven so as to enlarge the entrance of the first winning opening 17 for 5 seconds set in step S17B of FIG. For this reason, the accessory ratio control means 60 g transmits information on the drive time of the enlargement member 36 to the enlargement member control means 59. Then, the enlargement member control means 59 controls the driving of the enlargement member 36 while referring to the transmitted information on the drive 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 in the first winning opening 17, the ball enters the ball support portion 42a of the ball guiding member 42, and the ball is guided to the third winning opening 18b along the rotation of the ball guiding member 42. A ball wins in the third winning opening 18b. When a detection signal is transmitted from the third winning opening sensor 29b to the winning ball detecting unit 51, the game control unit 50B determines that a ball has won the third winning opening 18b.

  When the ball has won the third winning opening 18b, the condition for shifting to the special game is satisfied, so the process proceeds to step S28B and shifts to the special game. On the other hand, when the ball does not win in the third winning opening 18b, for example, when the ball does not enter the ball supporting portion 42a of the ball guiding member 42 because the ball does not win in the first winning opening 17 Alternatively, if the ball enters the ball support portion 42a of the ball guiding member 42, but the ball wins toward the second winning port 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 shifting to the special game in step 28B in FIG. 18, the process proceeds to step S91 in FIG. 19, and the special game is started.
