Description

  The present invention relates to a bullet ball game machine that plays a game by firing a game ball on a game board.

  In a ball game machine, a game is played by firing a game ball on the game board and causing the game ball to flow down along the game board. On the board surface of the game board, there is a special symbol start opening through which a game ball flowing down along the board surface can enter, and the player is in response to the game ball entering the special pattern start opening. A jackpot lottery is performed to determine whether or not to execute a special profit state (a jackpot game) that is advantageous (for example, a large number of prize balls can be obtained).

  Based on the game ball entering the special symbol start port, the symbol variation operation in the special symbol display means arranged on the game board is started, and the symbol variation operation is stopped after a predetermined variation time has elapsed. When the result of the jackpot lottery is a jackpot, the special symbol for the jackpot is stopped on the special symbol display means, and then the special profit state is executed. On the other hand, when the result of the big hit lottery is lost, the special symbol display means stops the symbol.

  If the special symbol for jackpot that is stopped and displayed on the special symbol display means is a specific symbol (probability variation symbol), the probability variation game (probability variation mode) that has a high probability of winning the jackpot lottery after the special profit state ends Is to be executed. Since the next jackpot can be drawn in a relatively short time during the probability variation game, the player can obtain a large number of prize balls.

  For example, the following cited document 1 discloses a falling lottery (random lottery) for determining whether or not the probability varying game can be terminated (falling from the probability varying game) during the probability varying game.

JP 2003-169922 A

In patent document 1, when falling from a probability variation game (when winning a falling lottery), the player is immediately notified of this (fall notification).
However, since the end timing of the probability variation game is one when the game is stopped in the ball game machine, the player may determine that the game is stopped by the fall notification, and may interrupt the game and leave the ball game machine. There is.

On the other hand, if the fall from the probability variation game is not notified at all, since the end of the probability variation game is not notified, the player cannot recognize whether or not the probability variation game is being executed. For this reason, the gameability is lowered, and there is a risk that the player's interest in the game will be reduced.
SUMMARY OF THE INVENTION An object of the present invention is to provide a bullet ball game machine capable of suppressing a player's separation at the time of falling, while notifying or suggesting a player of falling from a probability variation game.

  The invention according to claim 1 is a bullet ball game machine (1) for playing a game by firing a game ball toward the game board (2), wherein the game ball can be detected on the board surface of the game board. The first symbol starting means (7) (special symbol starting means) provided and when the first symbol starting means detects a game ball, a first profit state (special profit state) advantageous to the player is generated. The first profit state lottery means (30) (special profit state lottery means) for executing the first profit state lottery (special profit state lottery) of whether or not to perform, and a predetermined symbol variation operation can be displayed. The symbol display means (4) for stopping and displaying the symbols after the end of the fluctuating operation, and the first profit state generating means (30) for generating the first profit state when the result of the first profit state lottery is winning. (Special profit state generating means) and when the predetermined first condition is satisfied, When a game ball is detected by the probability variation game executing means (30) for executing the probability variation game having a high winning probability of the first profit state lottery based on the operation of the one profit state, and the first symbol starting means, A falling lottery means (30) for executing a falling lottery for determining whether or not to end the probability changing game being executed by the probability changing game execution means, and a variation pattern determination table for storing a plurality of types of variation pattern determination tables (33). Setting is made by a storage means (32), a fluctuation pattern determination table setting means (30) for selecting and setting one fluctuation pattern determination table from the plurality of types of fluctuation pattern determination tables, and the fluctuation pattern determination table setting means. The variation pattern for the symbol variation operation in the symbol display means is determined using the variation pattern determination table A variation pattern determining means (30), a symbol variation operation control means (36) for controlling execution of the symbol variation operation in the symbol display means according to the variation pattern determined by the variation pattern determining means, and winning the falling lottery From the variation pattern determination table previously set by the variation pattern determination table setting means, on condition that the symbol variation operation of the number of standby times has been executed in the symbol display means after the probability variation game is ended. The ball ball game machine includes table fall changing means (30) for changing to another fluctuation pattern determination table different from the fluctuation pattern determination table.

In addition, although the alphanumeric character etc. in a parenthesis represent the corresponding component in embodiment mentioned later, it is not the meaning which limits a claim to embodiment. The same applies hereinafter.
The symbol change operation in the symbol display means is an operation in which a symbol is displayed on the symbol display means, and the symbol changes in a predetermined order among the plurality of types of symbols one after another. For example, when the plurality of types of symbols are 10 types of single-digit numbers from 0 to 9, the display symbols change in the order of 0 → 1 → 2 →... → 8 → 9 → 0. Say.

The variation pattern refers to the pattern variation operation pattern.
According to the above configuration, during the probability variation game, the variation pattern is determined using the predetermined variation pattern determination table. Then, when the falling lottery is won and the execution of the symbol variation operation of the number of standbys is completed after the probability variation game is terminated, the variation pattern determination table is changed. By changing the variation pattern selection table as described above, the mode of the symbol variation operation displayed on the symbol display means can be made different from the previous one, thereby notifying or informing the player of the fall from the probability variation game. be able to. Since the change timing of the variation pattern determination table is shifted from the winning timing of the falling lottery, the falling timing from the probability variation game can be blurred to the player. As a result, the player can be retained by the ball game machine even after falling from the probability-changing game, and therefore, the player can be prevented from leaving when falling.

  According to a second aspect of the present invention, the plurality of types of variation pattern determination tables stored in the variation pattern determination table storage means include a first selection table group (32A) and a second selection table group (32B). It is included in any one of a plurality of selection table groups (32A, 32B, 32C, 32D), and the table fall changing means has the fluctuation pattern determination table set by the fluctuation pattern determination table setting means, 2. The bullet ball game machine according to claim 1, wherein the variation pattern determination table included in the first selection table group is changed to the variation pattern determination table included in the second selection table group.

  According to this configuration, during the probability variation game, the variation pattern is determined using the variation pattern determination table included in the first selection table group. Then, at the timing when the symbol variation operation for the number of standbys is finished after winning the falling lottery and the probability variation game is completed, the variation pattern determination table is changed from the variation pattern determination table included in the first selection table group, The variation pattern determination table included in the second selection table group is changed.

  The invention according to claim 3 is provided on the board surface of the game board, the second symbol starting means (6) (ordinary symbol starting means) arranged to detect the game ball on the board surface of the game board. When the first symbol starting means detects the gaming ball, the ordinary electric accessory (8) for changing the degree of detection of the game ball in the first symbol starting means, and the second symbol starting means detects the gaming ball. 2nd profit state lottery means for executing a second profit state lottery (normal profit state lottery) as to whether or not to generate a second profit state (normal profit state) that makes it easy for the symbol starting means to detect a game ball (30) (normal profit state lottery means) and second symbol display means (12) (normal symbol display) for displaying the result of the second profit state lottery based on the detection of the game ball of the second symbol starting means Means) and the result of the second profit state lottery is a win The second profit state generating means (30) (ordinary profit state generating means) for generating the second profit state, and when the predetermined second condition is satisfied, based on the operation of the first profit state, (2) Support game execution means (30) for executing a support game for increasing the frequency of occurrence of a profit state, and support game execution for ending execution of the support game by the support game execution means when a predetermined third condition is satisfied Ending means (30), wherein the plurality of selection table groups includes a third selection table group (32C) different from the first and second selection table groups, and the ball game machine includes the support game The variation pattern determination table set by the variation pattern determination table setting means at the end of the process is changed to the variation pattern included in the first selection table group. May further comprise a support end changing means for changing the change pattern determination table included from the constant table in the third selection table group (30).

In the invention according to claim 4, the average (α, β, γ, δ) of the time required for executing the variation pattern determined by the variation pattern determination table included in each of the selection table groups is different from each other. A bullet ball game machine according to claim 2 or 3.
According to this configuration, the time required for executing the symbol variation operation defined by the variation pattern differs for each pattern group. When the set variation pattern determination table is changed, the symbol variation operation executed in the symbol display means is different in average of the required time from the previous symbol variation operation. Therefore, the player can grasp the change of the set variation pattern determination table based on the symbol variation operation executed in the symbol display means. Therefore, by changing the variation pattern determination table, it can be suggested to the player that the player has fallen from the probability variation game.

  Further, as described in claim 5, a plurality of types of first symbols (special symbols) can be displayed, and the result of the first profit state lottery based on the detection of the game ball by the first symbol starting means is obtained. It further includes first symbol display means (11) (special symbol display means) for displaying, and the symbol display means includes effect display means (4) capable of displaying a plurality of types of effect symbols. May be.

  In this case, as described in claim 6, the ball game machine includes the fluctuation pattern determination table storage unit, the fluctuation pattern determination table setting unit, and the symbol fluctuation operation control unit, and the ball game machine A main control unit (20) for controlling the game related to the game and an effect control unit (22) for controlling the effect display means, wherein the main control unit performs the effect operation of the effect display means. And a control command output means (30) for outputting a control command for control to the effect control section, wherein the effect control section is configured to output the effect display means based on the control command from the control command output means. It may be one that controls.

  In this case, as described in claim 7, the plurality of types of variation pattern determination tables stored in the variation pattern determination table storage means include a first selection table group (32A) and a second selection table. It is included in any one of a plurality of selection table groups (32A, 32B, 32C, 32D) including the table group (32B), and the table drop change means is set by the variation pattern determination table setting means. The variation pattern determination table is changed from the variation pattern determination table included in the first selection table group to the variation pattern determination table included in the second selection table group, and is included in the first selection table group. Based on the variation pattern determination lottery using the variation pattern determination table, the production control unit A predetermined control command included in one command group is given, and based on a variation pattern determination lottery using a variation pattern determination table included in the second selection table group, the effect control unit On the other hand, a predetermined control command included in the second command group is given, and the production control unit is provided when the control command included in the second command group is given from the control command output means. May control the effect display means in a mode different from the case where the control command included in the first command group is given from the control command output means.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a schematic front view of a game board 2 of a ball game machine 1 according to an embodiment of the present invention. The ball game machine 1 includes a game board 2 and a front frame (not shown) for holding the game board 2. A handle (not shown) for adjusting the momentum of a game ball launched from a launching device (not shown) is disposed on the right side of the front lower part of the front frame. The handle is rotatably held on the front frame. A player can launch a game ball from the launching device toward the game board 2 by gripping and rotating the handle that is rotatably provided in the ball game machine 1, and the rotation of the handle. By adjusting the angle, the momentum of the game ball launched toward the game board 2 can be adjusted.

  On the board surface of the game board 2, a substantially arc-shaped guide rail 3 for guiding a game ball launched from the launch device to the upper side (upper left side) of the game board 2 is disposed. A large number of obstacle nails 5 (only some of the obstacle nails 5 are shown in FIG. 1) are arranged on the surface of the game board 2, and extend along the guide rails 3 from the upper left side of the game board 2. The game ball released to the upper right and downward flows down along the board surface of the game board 2 through a number of obstacle nails 5.

A liquid crystal display unit (effect display means) 4 is disposed at the center of the game board 2. The liquid crystal display unit 4 can execute the symbol variation operation of the effect symbol during the game of the ball game machine 1 and can stop the effect symbol after the symbol variation operation is finished, and if necessary. A predetermined message (such as a notice) can be displayed.
A special symbol starting port (first symbol starting means, special symbol starting means) 7 is disposed at the lower part of the game board 2. The special symbol start port 7 is provided so that a game ball flowing down along the board surface of the game board 2 can enter (the game ball can be detected).

  In the game board 2, an electric tulip accessory (ordinary electric accessory) 8 including a pair of blades is disposed in association with the special symbol start opening 7. The electric tulip accessory 8 is usually constricted so that the tip portions of the blades are close to each other. And in the state where the electric tulip accessory 8 is expanded, the frequency of entering the game ball into the special symbol starting port 7 is higher than when the electric tulip accessory 8 is in an approaching state.

  When a game ball enters the special symbol start port 7 (the special symbol start port 7 detects a game ball), a predetermined number (for example, three balls) of prize balls are awarded to a prize ball payout device 56 described later (see FIG. 2). Will be paid out. In addition, a big win lottery for determining whether or not to execute (activate) a special profit state (first profit state) advantageous to the player as the game ball enters the special symbol starting port 7 1 profit state lottery, special profit state lottery) are executed. In addition, during a probability variation game, which will be described later, a falling lottery for determining whether or not to end the probability variation game is executed as the game ball enters the special symbol starting port 7. The winning (falling) probability of this falling lottery is, for example, 1/10. The falling lottery is executed for each symbol changing operation of the special symbol (first symbol) in the special symbol display means (first symbol display means) 11.

  Below the special symbol start opening 7, for example, a large winning opening 9 having a long rectangular shape on the left and right is arranged. The big winning opening 9 is formed in a size that allows a plurality of (for example, 3 to 4) game balls to enter simultaneously in the horizontal direction. In connection with the big prize opening 9, a big prize opening opening / closing plate (special electric accessory) 10 capable of opening and closing the big prize opening 9 is provided. The big prize opening / closing plate 10 can block the big prize opening 9 in a state along the board surface of the game board 2 and prevent the game ball from entering the big prize opening 9, and from this state, the big prize winning opening 9 can be prevented. A game ball that flows down onto the big prize opening 9 by opening the big prize opening 9 by tilting to the near side about a rotation shaft (not shown) arranged along the lower edge of the mouth 9. Can be introduced into the grand prize opening 9. When a game ball enters the big winning opening 9, a predetermined number (for example, 10 balls) of prize balls are paid out from the prize ball payout device 56 (see FIG. 2).

  A normal symbol start gate on the right side of the game board 2 (the right side of the liquid crystal display unit 4 on the board surface of the game board 2) allows a game ball flowing down along the board surface of the game board 2 to pass (detect the game ball). (Second symbol starting means, normal symbol starting means) 6 is disposed. When the game ball passes through the normal symbol start gate 6 (the normal symbol start gate 6 detects the game ball), whether or not the electric tulip accessory 8 is expanded (whether a normal profit state is generated) ) Is determined (second profit state lottery, normal profit lottery).

  A special symbol display means 11 and a normal symbol display means (second symbol display means) 12 are disposed in the outer region of the guide rail 3 in the upper right part of the game board 2. The special symbol display means 11 is for displaying the result of the jackpot lottery executed for the game ball entering the special symbol start port 7 by variably displaying the special symbol. The normal symbol display means 12 displays the result of the normal symbol lottery executed for the passage of the game ball to the normal symbol start gate 6 by variably displaying the normal symbol (second symbol). . The special symbol display means 11 and the normal symbol display means 12 are each constituted by, for example, a 7-segment display.

  In the special symbol display means 11, the symbol changing operation of the special symbol is realized by switching each symbol alternately between “8” and “−” at high speed. When a game ball enters the special symbol start port 7, the special symbol display means 11 starts the symbol changing operation of the special symbol. This special symbol variation operation is stopped after a predetermined symbol variation time has elapsed. When the jackpot lottery result is a jackpot (determined to execute the special profit state), a special jackpot symbol (for example, “7”) determined in advance is stopped and displayed on the special symbol display means 11. On the other hand, when the result of the big hit lottery is lost, a predetermined lost symbol (“−”) is stopped and displayed on the special symbol display means 11.

  When a game ball enters the special symbol start port 7 during the symbol variation operation or special profit state in the special symbol display means 11, the symbol variation operation of the special symbol in the special symbol display means 11 for the entered ball is predetermined. Up to a number (for example, 4) can be reserved. The special symbol changing operation of the special symbol display means 11 held is executed according to the reserved order after the special symbol changing operation of the special symbol display means 11 being executed is completed.

  In the normal symbol display means 12, the normal symbol changing operation is realized by switching each symbol alternately between “8” and “−” at high speed. When the game ball passes through the normal symbol start gate 6, the normal symbol display means 12 starts executing the normal symbol changing operation. The normal symbol changing operation of the normal symbol display means 12 is stopped after elapse of a predetermined time (for example, 2.7 seconds during a support game, which will be described later, and 27 seconds when the support game is not executed). When the normal symbol lottery is won, the winning normal symbol (for example, “7”) is stopped and displayed. After that, the electric tulip accessory 8 is expanded, and the special symbol start port 7 is repeatedly executed for a predetermined time (for example, 2.0 seconds twice during the support game, and 0.2 seconds when the support game is not executed). Is released once). If the result of the normal symbol lottery is out of place, the normal symbol display means 12 stops and displays the normal symbol for shifting (“−”).

  When the game ball passes through the normal symbol start gate 6 during the normal symbol changing operation of the normal symbol display means 12 or during the expansion operation of the electric tulip accessory 8, the normal symbol display for the passage of the game ball. Up to a predetermined number (for example, four) of symbol changing operations of ordinary symbols in the means 12 can be suspended. The normal symbol changing operation of the held normal symbol displaying means 12 is executed according to the reserved order after the normal symbol changing operation of the normal symbol displaying means 12 being executed is completed.

  The ball game machine 1 is provided with a probability variation game. The jackpot probability in the normal state (when the probability variation game is not executed) is set to 1/400, for example. On the other hand, the probability that the special profit state is determined to be executed by the jackpot lottery in the probability variation game (hit probability) is set to a probability higher than the jackpot probability in the normal state, for example, 1/40. For this reason, the probability variation game (high probability) is more likely to be a big hit than when the probability variation game is not executed (low probability).

  In addition, a support game is prepared for the ball game machine 1. When the support game is not executed, the symbol variation time of the normal symbol of the normal symbol display means 12 with respect to the passage of the game ball to the normal symbol start gate 6 is 27.0 seconds, for example, and the winning probability of the normal symbol lottery is, for example, 1/100 The number of times of opening of the special symbol start port 7 (expansion of the electric tulip accessory 8) at the time of winning the normal symbol lottery is, for example, once, and the time required for each opening is, for example, 0.2 seconds. Therefore, when the support game is not executed, the electric tulip accessory 8 is rarely expanded, so that the game balls flowing down the game board 2 hardly enter the special symbol starting port 7.

On the other hand, during the support game, the symbol variation time of the normal symbol display means 12 for the passing of the game ball to the normal symbol start gate 6 is, for example, 2.7 seconds, and the winning probability of the normal symbol lottery is, for example, 1/1. .1, the number of times the special symbol start port 7 is opened at the time of winning the normal symbol lottery is, for example, 2 times, and the time required for each opening is, for example, 2.0 seconds.
In this way, during the support game, the symbol variation time of the normal symbol display means 12 with respect to the passing of the game ball to the normal symbol start gate 6 is shorter than when the support game is not executed, and the winning probability of the normal symbol lottery is small. The degree of expansion of the electric tulip accessory 8 (the degree of opening of the special symbol starting port 7 (including the number of times of opening and the time required for each opening)) at the time of winning the normal symbol lottery is high. Accordingly, during the support game, the electric tulip accessory 8 is frequently expanded (the occurrence frequency of the normal profit state is increased), and thus the game ball flowing down the board surface of the game board 2 during the support game is generated. It becomes easy to enter the special symbol start opening 7.

In addition, since the symbol variation time of the special symbol display means 11 for the game ball entering the special symbol start port 7 during the support game is shorter than when the support game is not executed, each support game is referred to as a “short-time game”. Can also be rephrased.
The support game and the probability variation game are independent of each other. Specifically, the support game and the probability variation game can be executed together (simultaneously), and only one of the support game and the probability variation game can be executed, and both the support game and the probability variation game can be executed. It is also possible not to execute. In this ball game machine 1, the support game and the probability variation game are generated in conjunction with each other, but the probability variation game is ended regardless of whether or not the support game is in progress. The game ends regardless of whether the game is in progress. The internal state of the ball game machine 1 is a state in which a probability variation game and a support game are in progress, a state in which a probability variation game is in progress and a support game is not executed, and a state in which the probability change game is not executed and There are four states (existing): a state in which a support game is in progress, and a state in which the probability variation game is not executed and the support game is not executed.

  The result of the big hit lottery is displayed on the special symbol display means 11 as described above, but is displayed not only on the special symbol display means 11 but also on the liquid crystal display unit 4. That is, during the special symbol changing operation of the special symbol display means 11, the design changing operation of the effect symbol by the liquid crystal display unit 4 is executed. When the result of the jackpot lottery is a jackpot, the jackpot effect symbol is stopped and displayed on the liquid crystal display unit 4 after the symbol changing operation of the effect symbol is completed. On the other hand, when the result of the big hit lottery is out of date, the effect symbol for losing is stopped and displayed on the liquid crystal display unit 4 after the end of the symbol changing operation of the effect symbol.

  Specifically, in the display screen of the liquid crystal display unit 4, three symbol display positions are set side by side, and when the jackpot lottery result is displayed, it is first displayed at the three symbol display positions. The effect symbols (numbers 0 to 9 in this embodiment) fluctuate at high speed, and the execution of the symbol variation operation of the effect symbols is started. When the predetermined time has elapsed, the symbol variation operation at the three symbol display positions is stopped in a predetermined order, and finally, one effect symbol is displayed in a stopped state at each symbol display position. The combination of effect symbols representing the result of the big hit lottery is displayed on the liquid crystal display unit 4.

  In the effect mode in the liquid crystal display unit 4, the effect symbols are stopped and displayed at two symbol display positions in the display screen of the liquid crystal display unit 4, and the effect symbols are stopped and displayed at the remaining one symbol display position. Whether it is a big hit or not, without going through the so-called reach state, the symbol change operation (out of reach) is displayed in three symbol display positions, and three symbols are displayed after normal reach. After performing the symbol change operation in which the effect symbol for jackpot or the effect symbol for losing is displayed at the position and the first super reach, the effect symbol for jackpot or the effect symbol for losing is displayed at the three symbol display positions. After the 2nd super reach, the design symbol for jackpot or the design symbol for losing appears at the three symbol display positions. It includes symbol variation operation and being.

  The normal reach is a reach in which the effect symbol at the remaining one symbol display position slowly stops at a substantially constant speed and then stops. The super reach is, for example, a reach in which the effect symbol at the remaining one symbol display position stops after varying at various fluctuation speeds longer than the normal reach. The second super reach has a longer variation time than the first super reach.

  During the special profit state, the big prize opening 9 is opened by swinging the big prize opening / closing plate 10. In the special profit state, the grand prize opening 9 is opened until a predetermined time (for example, 30 seconds) elapses or until a predetermined number of gaming balls (for example, 10 balls) enter the big prize opening 9 in advance. Such an operation is performed for a number of rounds (for example, 15 rounds) with an interval of a predetermined time (for example, 1.0 second), assuming that the operation of the big prize opening / closing plate 10 is one round. The number of prize balls that a player can acquire in one special profit state is, for example, about 1500 (10 (balls / ball) × 10 (balls / round) × 15 (round)).

  As special symbols for jackpots that are stopped and displayed on the special symbol display means 11, one or more types of probability variation symbols (for example, “11” and “12”) and one or more types of non-probability variation symbols (for example, “13” and “13”) 14 "). When the probability variation symbol is selected as the special symbol for jackpot, the probability variation game is immediately executed after the end of the special profit state (satisfaction of the first condition). This probability variation game is continuously executed until the winning of the falling lottery or the next jackpot is established, whichever comes first.

  Further, when the probability variation symbol is selected as the special symbol for jackpot, the support game is also executed promptly after the special profit state ends (the second condition is established). This support game is a support game that is cut in number of times in which a symbol variation operation of M times (M is a predetermined natural number) is set. Note that “the support game with the number of symbol change operations set to M times” means that the M symbol change operation in the special symbol display means 11 from the start (that is, after the end of the special profit state) is executed. Or a support game that is continuously executed until the next jackpot is established, whichever comes first (satisfaction of the third condition).

On the other hand, when the non-probable variation symbol is selected as the special symbol for jackpot, the support game is not executed. That is, after the special profit state ends, the probability variation game is not executed, and the support game is not executed.

That is, the effect control board 22 and the liquid crystal control board 23 are connected via the effect interface board 21.

  The main control board 20 is connected to various game parts of the game board 2 via the game board relay board 25. Specifically, on the game board relay board 25, the game ball has entered the normal symbol start gate passage sensor 52 for detecting that the game ball has passed through the normal symbol start gate 6, or the big winning opening 9. A special winning opening entrance ball sensor 53 and the like for detecting this are connected. The detection signal from the normal symbol start gate passage sensor 52 and the detection signal from the special winning opening entrance ball sensor 53 are input to the main control board 20 via the game board relay board 25. Further, the game board relay board 25 has a tulip drive mechanism (including solenoids, for example) 55 for driving the electric tulip accessory 8 and a large prize opening opening / closing mechanism (for opening and closing the special prize opening opening / closing plate 10). For example, a solenoid is included.) 54 is connected. The main control board 20 controls the special prize opening / closing mechanism 54 and the tulip driving mechanism 55 via the game board relay board 25.

  Further, special symbol display means 11, normal symbol display means 12, special symbol start-up entrance ball sensor 51 and the like are directly connected to the main control board 20. The main control board 20 is supplied with a detection signal from a special symbol start-up entrance sensor 51. Further, the main control board 20 controls the special symbol changing operation of the special symbol display unit 11 and the normal symbol changing operation of the normal symbol display unit 12.

  The microcomputer mounted on the main control board 20 includes a CPU 30 and a memory 31. The memory 31 includes a variation pattern selection table storage unit (variation pattern determination table storage means) 32, a special symbol start memory 41, a special symbol hold counter 42, a normal symbol start memory 45, and a normal symbol hold counter. 46, a probability variation flag 47, a support game flag 48, a support game rotation number counter 49, a table switching counter 50, and a probability variation maintenance effect flag 60.

A variation pattern selection table (variation pattern determination table) 33 for selecting and determining a variation pattern that is a pattern variation design pattern in the liquid crystal display unit 4 is stored in the variation pattern selection table storage unit 32. The fluctuation pattern selection table storage unit 32 and the fluctuation pattern selection table 33 will be described in detail later.
In the special symbol start memory 41, the result of the jackpot lottery executed for the game ball entering the special symbol start port 7 (a jackpot determination random number described later, a jackpot symbol determination random number described later, and a variation pattern described later). The random number for selection) and the result of the falling lottery executed for the game ball entering the special symbol starting port 7 (the random number for falling lottery described later) are stored (each random number is collectively referred to as “starting memory”). Sometimes). Here, “the result of the jackpot lottery” means a random number value (a value of a jackpot determination random number, a value of a jackpot symbol determination random number, and a random number for variation pattern selection) acquired based on entering the special symbol start port 7 Value). However, as a matter of course, instead of storing these random number values, the result of winning by comparing the determined random number value with a predetermined jackpot winning value may be stored.

The special symbol start memory 41 can store up to five jackpot lottery results (ie, start memories), one of which is used for executing the special symbol display operation on the special symbol display means 11. , And the other four are stored for holding the special symbol variation operation.
If a game ball enters the special symbol start port 7 in a state in which the special symbol is not changing, is not in a special profit state, and is not suspended, The result of the jackpot lottery performed for is stored in the special symbol start memory 41 for execution. Then, immediately after that, the symbol variation operation of the special symbol corresponding to the stored jackpot lottery result (starting memory) is started. On the other hand, when a game ball enters the special symbol start opening 7 in the state where the start memory is already stored for execution in the special symbol start memory 41, during the special symbol variation operation, or during the special profit state The result of the jackpot lottery performed for that ball is stored in the special symbol start memory 41 for holding, and the number of start memories stored for holding is the special symbol holding counter. 42.

  The result of the jackpot lottery stored for holding in the special symbol start memory 41 is that the special symbol corresponding to the start memory stored for execution is not in the special profit state when the symbol variation operation corresponding to the start memory is completed. Are sequentially moved up and stored for execution. As a result, the special symbol changing operation corresponding to the result of the jackpot lottery that has been put on hold is sequentially executed.

When the normal symbol lottery is won, the electric tulip accessory 8 is in an expanded state (for example, 2.0 seconds is executed twice during the support game, and 0.2 seconds is executed once when the support game is not executed). It is said.
The normal symbol start memory 45 stores the result of the normal symbol lottery performed for the passage of the game ball to the normal symbol start gate 6. The normal symbol start memory 45 can store up to five normal symbol lottery results, one of which is used to execute the normal symbol changing operation of the normal symbol display means 12 and the other four symbols. One can be stored as a hold for a symbol variation operation of a normal symbol. In the state where the symbol variation of the normal symbol display means 12 is not performed, the electric tulip accessory 8 is not being expanded, and the symbol variation operation of the normal symbol is not suspended, the game ball is not changed to the normal symbol start gate 6. Is passed, the result of the normal symbol lottery performed for the passage is stored for execution in the normal symbol start memory 45, and immediately after that, according to the stored result of the normal symbol lottery In addition, the symbol changing operation of the normal symbol is executed. On the other hand, in the case where the result of the normal symbol lottery is already stored for execution in the normal symbol start memory 45, or when the game ball passes through the normal symbol start gate 6 during the expansion operation of the electric tulip accessory 8 The result of the normal symbol lottery performed for the passage is stored in the normal symbol start memory 45 for holding, and the number of times of the result of the normal symbol lottery stored for the holding is the normal symbol. It is counted by the hold counter 46 for use. The result of the normal symbol lottery stored for holding in the normal symbol start memory 45 is the electric tulip bonus when the normal symbol variation operation corresponding to the result of the normal symbol lottery stored for execution is completed. On the condition that the expansion operation of 8 is not in progress, it is sequentially moved up and stored for execution. As a result, the normal symbol changing operation according to the result of the normal symbol lottery held is sequentially executed.

The probability variation flag 47 is used to store whether or not a probability variation game is in progress. The probability variation flag 47 is set to “1” during a probability variation game, and “ 0 "is set.
The support game flag 48 is used for storing whether or not a support game is in progress. “1” is set during the support game, and “0” is set when the support game is not executed. Set.

The support game rotation number counter 49 is for counting the number of remaining symbol variation operations during the support game.
The table switching counter 50 is for counting the number of remaining symbol variation operations until the timing of stopping the probability variation maintenance effect.
Whether the probability variation maintenance effect flag 60 is executing a probability variation maintenance effect that informs or suggests that a probability variation game is in progress, or is it performing a fall effect that informs or suggests that the probability variation game has fallen It is for memorizing. “1” is set in the probability variation maintenance effect flag 60 during the probability variation maintenance effect, and “0” is set in the probability variation maintenance effect flag 60 during the fall effect.

  As will be described later, in the ball game machine 1, when the falling lottery is won during the probability variation game, the change pattern selection table for reference is not immediately changed, and the number of waiting is predetermined after winning the falling lottery. The reference variation pattern selection table is changed at the timing when the N symbol variation operations have been completed. The probability variation maintenance effect flag 60 is used for determining this change timing.

  A microcomputer (not shown) mounted on the effect control board 22 includes a CPU and a memory. The effect control substrate 22 includes an effect mode storage unit 35 and an effect mode lottery unit (symbol changing operation control means) 36, and the effect mode storage unit 35 and the effect mode lottery unit 36 are mounted on the effect control board 22. This is realized by a microcomputer. The effect mode storage unit 35 is provided with an effect mode selection table 37 for selecting and determining the pattern change operation mode of the effect symbols in the liquid crystal display unit 4. The effect mode selection table 37 will be described in detail later.

The main control board 20 outputs a control command CMD toward the effect control board 22. A control command CMD from the main control board 20 is given to the effect control board 22 via the effect interface board 21.
The effect control board 22 determines a specific effect mode of the liquid crystal display unit 4 based on the control command CMD from the main control board 20, and sends the control command CMD ′ on which the effect mode is described to the liquid crystal display control board 23. Send. The liquid crystal display control board 23 controls the display of the liquid crystal display unit 4 based on a control command CMD ′ (in this case, a liquid crystal control command) sent from the effect control board 22. In addition, the effect control board 22 lights (flashes) game lamps (not shown) provided on the front surface of the ball game machine 1 or the front surface of the game board 2 based on the control command CMD from the main control board 20. / Controls the light-off operation and the sound output of a speaker (not shown).

Further, the main control board 20 outputs a control command CMD ″ toward the payout control board 24. A control command CMD ″ output from the main control board 20 is given to the payout control board 24 via a main board relay board (not shown). The payout control board 24 controls the payout operation of the prize ball payout device 56 based on the control command CMD ″ from the main control board 20.
The control command CMD output from the main control board 20 to the effect control board 22 has a 2-byte configuration including mode data that is 1-byte digital data and event data that is 1-byte digital data. . In each control command CMD, the mode data and event data are transmitted and received individually in succession. The mode data is for designating the outline portion of the production content, and has a hexadecimal 2-digit value. The event data is for designating a specific part of the production contents, and has a hexadecimal 2-digit value.

Examples of the control command CMD transmitted from the main control board 20 to the effect control board 22 include a variation pattern command (A0 ** [H]) and a symbol command. All the mode data of the variation pattern command have a value of “A0”.
The variation pattern command (A0 ** [H]) notifies the effect control substrate 22 of the variation pattern selected and determined on the main control substrate 20. The value of the event data of the variation pattern command indicates the number of the variation pattern. The letter [H] written at the end of the command data is a subscript, meaning that it is a hexadecimal number.

  The symbol command is used to notify the effect control substrate 22 of the special symbol for jackpot and the off symbol determined on the main control substrate 20 by lottery. The event data of the symbol command has values corresponding to both the type of the special symbol displayed on the special symbol display means 11 and the type of the off symbol. By transmitting the symbol command, the effect control board 22 can select and determine the effect symbol to be displayed on the liquid crystal display unit 4 after the symbol changing operation of the effect symbol is completed.

FIG. 3 is a diagram for explaining the variation pattern selection table 33 stored in the variation pattern selection table storage unit 32.
The variation pattern selection table storage unit 32 is provided with many types (plural types) of variation pattern selection tables 33. These various types of variation pattern selection tables 33 include a first selection table group (first selection table group) 32A, a second selection table group (second selection table group) 32B, and a third selection table group (third selection table group). ) While being included in any of a plurality of selection table groups such as 32C and the fourth selection table group 32D, it is stored in the variation pattern selection table storage unit 32.

  One variation pattern selection table 33 among the many types of variation pattern selection tables 33 stored in the variation pattern selection table storage unit 32 is a jackpot determination result, a value of a support game flag 48, and a probability variation maintenance effect flag 60 described later. , The value of the special symbol hold counter 42, the random number for selecting the variation pattern obtained when the game ball enters the special symbol start port 7 (step S5 in FIG. 9 described later), etc. Set as a variation pattern selection table. In a variation pattern selection lottery to be described later (step S24 in FIG. 9 to be described later), with reference to this reference variation pattern selection table, a game ball enters the special symbol start port 7 (step S5 in FIG. 9 to be described later). ) Acquired, the type of variation pattern to be executed, in other words, the type of variation pattern command to be sent to the effect control board 22 is selected and determined.

  The first selection table group 32A includes multiple types (plural types) of variation pattern selection tables 33A (hereinafter referred to as “first variation pattern selection table 33A”). The average time required for executing the variation pattern selected in the variation pattern selection lottery executed with reference to the first variation pattern selection table 33A (hereinafter referred to as “first variation pattern selection lottery”) (hereinafter referred to as “first variation pattern selection lottery”). , “Average fluctuation time of fluctuation pattern” is α (sec) (α = a · T1 + b · T2 + c · T3 + d · T4 as will be described later). The first variation pattern selection table 33A selected from the first selection table group 32A is selected as a variation pattern for reference when the probability variation maintenance effect is being performed and the internal state of the ball game machine 1 is in the support game. Set as a table.

  The second selection table group 32B includes multiple types (plural types) of variation pattern selection tables 33B (hereinafter referred to as “second variation pattern selection table 33B”). The average variation time of the variation pattern selected in the variation pattern selection lottery executed with reference to the second variation pattern selection table 33B (hereinafter referred to as “second variation pattern selection lottery”) is β (sec) (described later). Β = e · T1 + f · T2 + g · T3 + h · T4). When the probability variation maintenance effect is not executed and the internal state of the ball game machine 1 is in the support game, one second variation pattern selection table 33B selected from the second selection table group 32B is used for reference. Set as a variation pattern selection table.

  The third selection table group 32C includes multiple types (plural types) of variation pattern selection tables 33C (hereinafter referred to as “third variation pattern selection table 33C”). The average fluctuation time of the fluctuation pattern selected in the fluctuation pattern selection lottery executed with reference to the third fluctuation pattern selection table 33C (hereinafter referred to as “third fluctuation pattern selection lottery”) is γ (sec) (described later). Γ = i · T1 + j · T2 + k · T3 + l · T4). The third variation pattern selection table 33C selected from the third selection table group 32C is referenced when the probability variation maintenance effect is being executed and the internal state of the ball game machine 1 is not in the support game. Is set as a variation pattern selection table.

  The fourth selection table group 32D includes multiple types (plural types) of variation pattern selection tables 33D (hereinafter referred to as “fourth variation pattern selection table 33D”). The average variation time of the variation pattern selected in the variation pattern selection lottery executed by referring to the fourth variation pattern selection table 33D (hereinafter referred to as “fourth variation pattern selection lottery”) is δ (sec) (described later). Δ = m · T1 + n · T2 + t · T3 + u · T4). When the probability variation maintenance effect is not executed and the internal state of the ball game machine 1 is the non-execution state of the support game, one fourth variation pattern selection table 33D selected from the fourth selection table group 32D is It is set as a variation pattern selection table for reference. The magnitude relationship between the lengths of the average fluctuation times of these fluctuation patterns is that when conditions related to selection of fluctuation patterns other than execution / non-execution of the probability fluctuation maintenance effect and execution / non-execution of the support game are common (for example, When the result of the big hit lottery is out of place and the value of the separate symbol holding counter 42 is 1 or less), α <β <γ <δ.

The variation pattern selection tables 33A to 33D set as the reference variation pattern selection table are changed to other selection table groups 32A to 32D that do not include the selection table being set during execution of the game in the ball game machine 1. It is possible to change to the included variation pattern selection tables 33A to 33D.
FIG. 4 is a diagram for explaining the relationship between the selection table groups 32A to 32D and the variation patterns selected by the variation pattern selection tables 33A to 33D included in the selection table groups 32A to 32D.

  In this ball game machine 1, a predetermined number (for example, four in FIG. 4) of the variation time of the symbol variation operation defined by the variation pattern is set. Specifically, four variation times of “variation 1”, “variation 2”, “variation 3”, and “variation 4” are set. Variation 1 is a variation time T1 for symbol variation operation for out-of-reach (out-of-reach out-of-reach) variation, and variation 2 is variation time T2 for symbol variation operation for normal reach (indicated as “normal” in FIG. 4). It is. The variation 3 is a variation time T3 for the symbol variation operation for the first super reach (described as “super 1” in FIG. 4), and the variation 4 is the second super reach (“super 2” in FIG. 4). And a variation time T4 for the symbol variation operation.

  In the first variation pattern selection lottery, the probability that variation 1 is selected (hereinafter referred to as “variation 1 selection probability”), the probability that variation 2 is selected (hereinafter referred to as “variation 2 selection probability”), and variation 3. Are selected (hereinafter referred to as “selection probability of variation 3”), and the probability of selection of variation 4 (hereinafter referred to as “selection probability of variation 4”) are a%, b%, c% and d%. The average fluctuation time of the fluctuation pattern selected in the first fluctuation pattern selection lottery is α (sec) (α = a · T1 + b · T2 + c · T3 + d · T4).

As a result of the first variation pattern selection lottery, a variation pattern command (A0 ** [H]) to be sent to the effect control board 22 is determined. This variation pattern command (A0 ** [H]) is selected from predetermined variation pattern commands (for example, A001 [H] to A03F [H], first command group).
The selection probability of variation 1, the selection probability of variation 2, the selection probability of variation 3, and the selection probability of variation 4 in the second variation pattern selection lottery are e%, f%, g%, and h%, respectively. The average fluctuation time of the fluctuation pattern selected in the second fluctuation pattern selection lottery is β (sec) (β = e · T1 + f · T2 + g · T3 + h · T4).

As a result of the second variation pattern selection lottery, a variation pattern command (A0 ** [H]) to be sent to the effect control board 22 is determined. This variation pattern command (A0 ** [H]) is selected from predetermined variation pattern commands (for example, A041 [H] to A07F [H], second command group).
The selection probability (f%) of variation 2 in the second variation pattern selection lottery, the selection probability (g%) of variation 3 and the selection probability (h%) of variation 4 are the selection of variation 2 in the first variation pattern selection lottery. Probability (b%), selection probability of variation 3 (c%), and selection probability of variation 4 (d%) are higher. Therefore, the reach selection probability in the entire second variation pattern selection lottery is higher than the reach selection probability in the entire first variation pattern selection lottery. As a result, the average variation of the variation patterns selected in the second variation pattern selection lottery The time β (sec) is longer than the average variation time α (sec) of the variation pattern selected in the first variation pattern selection lottery (β> α).

  From another viewpoint, the reliability of the reach (variation 2 to variation 4) selected in the second variation pattern selection lottery (the probability of subsequently becoming a big hit) is the reach selected in the first variation pattern selection lottery ( This is different from the reliability of fluctuation 2 to fluctuation 4). Specifically, the normal reach selected in the second variation pattern selection lottery has lower reliability than the normal reach selected in the first variation pattern selection lottery, and the first super reach selected in the second variation pattern selection lottery. Is less reliable than the first super reach selected in the first variation pattern selection lottery. Further, the second super reach selected in the second variation pattern selection lottery has lower reliability than the second super reach selected in the first variation pattern selection lottery.

The selection probability of variation 1, the selection probability of variation 2, the selection probability of variation 3, and the selection probability of variation 4 in the third variation pattern selection lottery are i%, j%, k%, and l%, respectively. The average variation time of the variation pattern selected in the third variation pattern selection lottery is γ (sec) (γ = i · T1 + j · T2 + k · T3 + 1 / T4).
As a result of the third variation pattern selection lottery, a variation pattern command (A0 ** [H]) to be sent to the effect control board 22 is determined. This variation pattern command (A0 ** [H]) is selected from predetermined variation pattern commands (for example, A081 [H] to A0BF [H], a third command group).

  The selection probability (j%) of variation 2 in the third variation pattern selection lottery, the selection probability (k%) of variation 3, and the selection probability (l%) of variation 4 are the selection of variation 2 in the second variation pattern selection lottery. The probability (f%), the selection probability of variation 3 (g%), and the selection probability of variation 4 (h%) are higher. Accordingly, the reach selection probability in the entire third variation pattern selection lottery is higher than the reach selection probability in the entire second variation pattern selection lottery. As a result, the average variation of the variation patterns selected in the third variation pattern selection lottery The time γ (sec) is longer than the average variation time β (sec) of the variation pattern selected in the second variation pattern selection lottery (γ> β).

  From another viewpoint, the reliability of the reach (variation 2 to variation 4) selected in the third variation pattern selection lottery (the probability of subsequently becoming a big hit) is the reach selected in the second variation pattern selection lottery ( This is different from the reliability of fluctuation 2 to fluctuation 4). Specifically, the normal reach selected in the third variation pattern selection lottery has lower reliability than the normal reach selected in the second variation pattern selection lottery, and the first super reach selected in the third variation pattern selection lottery. Is less reliable than the first super reach selected in the second variation pattern selection lottery. Further, the second super reach selected in the third variation pattern selection lottery has lower reliability than the second super reach selected in the second variation pattern selection lottery.

The selection probability of variation 1, the selection probability of variation 2, the selection probability of variation 3, and the selection probability of variation 4 in the fourth variation pattern selection lottery are m%, n%, t%, and u%, respectively. The average fluctuation time of the fluctuation pattern selected in the fourth fluctuation pattern selection lottery is δ (sec) (δ = m · T1 + n · T2 + t · T3 + u · T4).
As a result of the fourth variation pattern selection lottery, a variation pattern command (A0 ** [H]) to be sent to the effect control board 22 is determined. This variation pattern command (A0 ** [H]) is selected from predetermined variation pattern commands (for example, A0C1 [H] to A0FF [H]).

  The variation 2 selection probability (n%), the variation 3 selection probability (t%), and the variation 4 selection probability (u%) in the fourth variation pattern selection lottery are the variations 2 selection in the third variation pattern selection lottery. Probability (j%), selection probability of variation 3 (k%), and selection probability of variation 4 (1%) are higher. Accordingly, the reach selection probability in the entire fourth variation pattern selection lottery is higher than the reach selection probability in the entire third variation pattern selection lottery. As a result, the average variation of the variation patterns selected in the fourth variation pattern selection lottery The time δ (sec) is longer than the average variation time γ (sec) of the variation pattern selected in the third variation pattern selection lottery (δ> γ).

  From another viewpoint, the reliability of the reach (variation 2 to variation 4) selected in the fourth variation pattern selection lottery (the probability of subsequently becoming a big hit) is the reach selected in the third variation pattern selection lottery ( This is different from the reliability of fluctuation 2 to fluctuation 4). Specifically, the normal reach selected in the fourth variation pattern selection lottery has lower reliability than the normal reach selected in the third variation pattern selection lottery, and the first super reach selected in the fourth variation pattern selection lottery. Is less reliable than the first super reach selected in the third variation pattern selection lottery. Further, the second super reach selected in the fourth variation pattern selection lottery has lower reliability than the second super reach selected in the third variation pattern selection lottery.

In this embodiment, in the first to fourth variation pattern selection lotteries, selectable variation patterns (in other words, selectable variation pattern commands) are different from each other and do not overlap.
Even if the time required for the symbol variation operation is the same, different variation patterns are given when the results of the jackpot lottery differ.

  The average variation time β of the variation pattern selected in the second variation pattern selection lottery is longer than the average variation time α of the variation pattern selected in the first variation pattern selection lottery. This can also be said that the variation pattern selected and determined in the second variation pattern selection lottery has a higher reach rate than the variation pattern selected in the first variation pattern selection lottery. When the variation pattern determination table for reference is changed from the first variation pattern selection table 33A to the second variation pattern selection table 33B, the symbol variation operation of the effect symbol executed in the liquid crystal display unit 4 is performed until then. The average of the required time is longer than the symbol variation operation. This can be paraphrased as an increase in the reach of the reach in the symbol variation operation of the effect symbol. Therefore, in the symbol variation operation of the effect symbol in the liquid crystal display unit 4, the player needs to change the reference variation pattern selection table by increasing the time required for the symbol variation operation or increasing the appearance frequency of the reach. Change can be grasped. Therefore, it is possible to suggest to the player that the game has fallen from the probability variation game.

  The average variation time δ of the variation pattern selected in the fourth variation pattern selection lottery is longer than the average variation time γ of the variation pattern selected in the third variation pattern selection lottery. This can also be said that the variation pattern selected and determined in the fourth variation pattern selection lottery has a higher reach rate than the variation pattern selected in the third variation pattern selection lottery. When the variation pattern determination table for reference is changed from the third variation pattern selection table 33C to the fourth variation pattern selection table 33D, the symbol variation operation of the effect symbol executed in the liquid crystal display unit 4 is performed until then. The average of the required time is longer than the symbol variation operation. This can be paraphrased as an increase in the reach of the reach in the symbol variation operation of the effect symbol. Therefore, in the symbol variation operation of the effect symbol in the liquid crystal display unit 4, the player needs to change the reference variation pattern selection table by increasing the time required for the symbol variation operation or increasing the appearance frequency of the reach. Change can be grasped. Therefore, it is possible to suggest to the player that the game has fallen from the probability variation game.

  In FIG. 4, the average variation time γ (sec) of the variation pattern selected in the third variation pattern selection lottery is longer than the average variation time β (sec) of the variation pattern selected in the second variation pattern selection lottery. The case of long (γ> β) is taken as an example, but the average variation time γ (sec) of the variation pattern selected in the third variation pattern selection lottery is the average variation time α (sec) of the first variation pattern selection lottery. Longer than the average variation time β (sec) of the second variation pattern selection lottery (β> γ> α). In this case, the selection probability (j%) of variation 2 in the third variation pattern selection lottery is higher than the selection probability (b%) of variation 2 in the first variation pattern selection lottery, and the variation in the second variation pattern selection lottery The probability can be set lower than the selection probability (f%) of 2. In addition, the selection probability (k%) of variation 3 in the third variation pattern selection lottery is higher than the selection probability (c%) of variation 3 in the first variation pattern selection lottery, and variation 3 in the second variation pattern selection lottery. It is possible to set a probability lower than the selection probability (g%). Furthermore, the selection probability (1%) of variation 4 in the third variation pattern selection lottery is higher than the selection probability (d%) of variation 4 in the first variation pattern selection lottery and variation 4 in the second variation pattern selection lottery. It is possible to set a probability lower than the selection probability (h%).

Note that the contents of the variation pattern selection tables 33A to 33D shown in FIG. 4 are examples, and the types of variation that can be selected are not limited to four, and may be five or more, or may be three or less. Good. In addition, it goes without saying that the contents of each variation pattern selection table 33 can be appropriately set as appropriate.
For example, the symbol variation operation (variation 1 to variation 4) included in the four selection table groups 32A to 32D has been described as being common to each other, but is included in a certain selection table group 32A to 32D. The symbol variation operation may be different from the symbol variation operations included in the other selection table groups 32A to 32D. Specifically, in the first selection table group 32A and the second selection table group 32B, instead of the symbol variation operation for detachment (variation 1), the symbol variation operation for detachment with support (during a support game) ( Variation 1 ′) (variation time for symbol variation operation (T1 ′ <T1)) may be provided. Further, in the second selection table group 32B and the fourth selection table group 32D selected when the probability variation game is not executed, a unique symbol variation operation (variation 5) may be provided.

  Furthermore, a common variation pattern selection table may be provided in the plurality of selection table groups 32A to 32D. For example, the plurality of variation pattern selection tables included in the first selection table group 32A and the plurality of variation pattern selection tables included in the third selection table group 32C may be common in part or all. The plurality of variation pattern selection tables included in the second selection table group 32B and the plurality of variation pattern selection tables included in the fourth selection table group 32D may be common in part or all. When a common variation pattern selection table is provided for a plurality of selection table groups in this way, the first to fourth variation pattern selection lotteries are executed using overlapping variation pattern tables.

  Furthermore, in this embodiment, a variation pattern is provided corresponding to each of the selection table groups 32A to 32D, and a common variation pattern is not provided between the plurality of selection table groups 32A to 32D. However, a common (overlapping) variation pattern may be provided between the plurality of selection table groups 32A to 32D. In this case, a common variation pattern command (A0 ** [H]) can be selected among the plurality of selection table groups 32A to 32D.

  5 to 8 are diagrams showing the effect mode selection table 37. Referring to FIG. 5, as an example of the variation pattern selected in the first variation pattern selection lottery, a variation pattern corresponding to a variation pattern command of A001 [H] can be cited. The variation time of this variation pattern is “variation 1”. When the variation pattern command of A001 [H] is input to the effect control board 22, it is possible to select an effect mode with or without a notice. As an advance notice, an X1 advance notice in which the character X appears can be exemplified. In this variation pattern, reach is not executed.

  An example of the variation pattern selected in the first variation pattern selection lottery is a variation pattern corresponding to a variation pattern command of A009 [H]. The variation time of this variation pattern is “variation 2”. When the variation pattern command of A009 [H] is input to the effect control board 22, one of reach A, reach B, and reach C is selectively executed as an effect mode. The reach A is a normal reach in which the character X appears. When the reach A is executed, an X1 notice in which the character X appears is executed as a notice executed before the reach is established.

  That is, in this ball game machine 1, the production mode based on the variation pattern selected in the second variation pattern selection lottery (see FIG. 6) and the production mode based on the variation pattern selected in the fourth variation pattern selection lottery ( The drop message (referred to as “fall effect” in FIGS. 6 and 8) is included in each of FIG. 8), but the effect mode based on the variation pattern selected in the first variation pattern selection lottery ( A fall message is not included in the production mode (see FIG. 7) based on the variation pattern selected in the third variation pattern selection lottery (see FIG. 5).

Therefore, in the symbol variation operation of the effect symbol in the liquid crystal display unit 4, the player can grasp the change of the reference variation pattern selection table when the fall message appears. Therefore, it is possible to notify the player that the game has fallen from the probability variation game.
In this ball game machine 1, the production mode based on the variation pattern selected in the first variation pattern selection lottery (see FIG. 5) and the production mode based on the variation pattern selected in the third variation pattern selection lottery (FIG. 7). Reference) corresponds to a probability variation maintenance effect that informs or suggests that a probability variation game is in progress after the probability variation game is entered. In the production mode shown in FIG. 5 and FIG. 7, it is not actively informing that the game is in a probability variation game, but is not actively informing of a fall from the probability variation game. It can be included in the probability variation maintenance effect in that the appearance frequency of the reach during the variable game is lower than the appearance frequency of the reach when the probability variable game is not executed.

Further, the effect mode based on the variation pattern selected in the second variation pattern selection lottery (see FIG. 6) and the effect mode based on the variation pattern selected in the fourth variation pattern selection lottery (see FIG. 8) This corresponds to a fall effect that informs or suggests that the game has fallen.
In addition, in order to actively notify that the probability variation game is being performed in the probability variation maintenance notification, a premier character that does not appear except during the probability variation maintenance notification appears, or a premium reach that does not appear other than during the probability variation maintenance notification. You may make it appear, or display the message to the effect that the probability variation game is in progress on the liquid crystal display unit 4.

FIG. 9 is a flowchart showing a flow of a ball entry process performed by the CPU 30 of the main control board with respect to a game ball entering the special symbol starting port 7.
During the game by the ball game machine 1, the CPU 30 monitors whether or not a game ball has entered the special symbol start port 7 based on the presence or absence of an input signal from the special symbol start port entrance sensor 51. (Step S1).

  When receiving an input signal from the special symbol start entrance ball sensor 51 (YES in step S1), the CPU 30 stores the number of start memories already stored in the special symbol start memory 41 (holding number), that is, the special symbol hold. The count value of the counter 42 is confirmed, and it is determined whether or not the count value has reached “4” (step S2). When the count value of the special symbol hold counter 42 is less than “4” (NO in step S2), the CPU 30 obtains a jackpot determination random number from a jackpot determination random number generator (not shown) (step S3). Further, the CPU 30 acquires a jackpot symbol determination random number from a jackpot symbol determination random number generator (not shown) (step S4), and acquires a variation pattern selection random number from the variation pattern selection random number generator (not illustrated) ( Together with step S5), a random number for falling lottery is obtained from a random number generator for falling lottery (not shown) (step S6).

Thereafter, the CPU 30 stores the jackpot determining random number, the jackpot symbol determining random number, the variation pattern selecting random number and the falling lottery random number (that is, starting memory) in the special symbol starting memory 41 (step S7), and for the special symbol. The count value of the hold counter 42 is incremented (+1) (step S8).
On the other hand, if the count value of the special symbol hold counter 42 is “4” (YES in step S2), the processing for the game ball entering the special symbol start port 7 is terminated without storing each random number.

10, FIG. 11, FIG. 12 and FIG. 13 are flowcharts showing the flow of processing in the special symbol display means 11 during the special symbol changing operation.
When the special symbol start memory 41 stores start memory (a jackpot determination random number, a jackpot symbol determination random number, a variation pattern selection random number and a falling lottery random number) (YES in step S11), a special profit state The CPU 30 makes a jackpot determination on the condition that it is not executed (NO in step S12) (steps S18 and S19).

  Specifically, prior to the jackpot determination, the CPU 30 refers to the value of the probability variation flag 47 and determines whether or not the internal state of the ball game machine 1 is in the probability variation game (step S13). When “0” is set in the probability variation flag 47 and the internal state of the ball game machine 1 is not in the probability variation game (NO in step S13), the processing of the CPU 30 proceeds to step S19. The CPU 30 performs jackpot determination based on a low probability (1/400) determination criterion (step S19).

  On the other hand, if the probability variation flag 47 is set to “1” and the internal state of the ball game machine 1 is executing the probability variation game (YES in step S13), the CPU 30 proceeds to step S6 in FIG. It is determined whether or not the falling lottery is won based on the acquired falling lottery random number (step S14: fall determination). If the value of the random number for falling lottery is a predetermined falling determination value, it is determined that the falling lottery is won (YES in step S15), and the value of the probability variation flag 47 is switched from “1” to “0”. , N (times) as the number of remaining symbol variation operations until the timing of switching the variation pattern selection tables 33A to 33D to the table switching counter 50 (the number of remaining symbol variation operations until the timing at which the probability variation maintaining effect is stopped). Is set (step S16). Further, if the random number for falling lottery is not a predetermined falling determination value, it is determined that the falling lottery is shifted (NO in step S15), the process of step S16 is skipped, and the value of the probability variation flag 47 is “1”. "".

  Next, the CPU 30 refers to the value of the probability variation flag 47 again (step S17) and makes a jackpot determination (steps S18 and S19). Specifically, when “1” is set in the probability variation flag 47 (YES in step S17), the CPU 30 performs a jackpot determination based on a determination criterion of a high probability (1/40) (step S18). On the other hand, when “0” is set in the probability variation flag 47 (NO in step S17), the CPU 30 performs a jackpot determination based on a determination criterion of low probability (1/400) (step S19).

When the result of the jackpot determination in step S18 or step S19 is a jackpot (YES in step S20), the CPU 30 determines a special jackpot symbol based on the jackpot symbol determination random number acquired in step S4 of FIG. 9 ( Step S21).
On the other hand, if the result of the jackpot determination in step S18 or step S19 does not result in a jackpot (NO in step S20), the CPU 30 is based on the loss symbol determination random number obtained from the loss symbol determination random number generator (not shown). A slip-off symbol is determined (step S22).

Further, the CPU 30 selects and determines the reference variation pattern selection table 33 based on the value of the support game flag 48 and the value of the probability variation maintenance effect flag 60 (step S23).
Specifically, when the value of the support game flag 48 is “1” and the value of the probability variation maintenance effect flag 60 is “1”, the first variation pattern selection table is selected from the first selection table group 31A. 33A is selected and determined, and the selected selection table 33A is set as a reference variation pattern selection table. Further, when the value of the support game flag 48 is “1” and the value of the probability variation maintenance effect flag 60 is “0”, the second variation pattern selection table 33B is selected from the second selection table group 32B. The selected and selected selection table 33B is set as a reference variation pattern selection table. Further, when the value of the support game flag 48 is “0” and the value of the probability variation maintenance effect flag 60 is “1”, the third variation pattern selection table 33C is selected from the third selection table group 32C. The determined selection table 33C is set as a reference variation pattern selection table. Furthermore, when the value of the support game flag 48 is “0” and the value of the probability variation maintenance effect flag 60 is “0”, the fourth variation pattern selection table 33D is selected from the fourth selection table group 32D. The selected selection table 33D is selected and set as a reference variation pattern selection table. That is, when the variation pattern selection tables 33A to 33D newly selected and determined are different from the reference variation pattern selection table so far, the reference variation pattern selection table is switched to the new variation pattern selection table. Will be (changed).

  Further, the CPU 30 of the main control board 20 refers to the reference variation pattern selection table 33 (33A to 33D), and based on the variation pattern lottery random number obtained in step S5 of FIG. The variation pattern of the symbol variation operation of the effect symbol in the liquid crystal display unit 4 executed together with the symbol variation operation of the special symbol in 11 is determined by lottery (step S24). That is, the variation pattern selection lottery described above is executed, and thereby, the variation pattern command to be sent to the effect control board 22 is selected and determined.

  Then, the CPU 30 of the main control board 20 sends the variation pattern command (A0 ** [H]) and the symbol command to the effect control board 22 (step S25). In addition, the production control board 22 sends a control command to the liquid crystal display control board 23 in response to the input of the fluctuation pattern command and the design command from the CPU 30, and starts executing the design variation operation of the production design in the liquid crystal display unit 4. (Step S26). In addition to the execution of the symbol variation operation in the liquid crystal display unit 4, the lighting (blinking) / extinguishing operation of the game lamp (not shown) and the sound output of the speaker (not shown) are controlled by the effect control board 22, respectively. .

After the variation time defined in the selected variation pattern has elapsed (YES in step S27), the CPU 30 ends the execution of the symbol variation operation for the special symbol in the special symbol display means 11 (step S28). In addition, at the end of the symbol variation time in the special symbol display means 11, the execution of the symbol variation operation of the effect symbol in the liquid crystal display unit 4 is terminated.
When the result of the jackpot determination in steps S18 and S19 is a jackpot, the CPU 30 stops displaying the jackpot special symbol determined in step S21 on the special symbol display means 11 (step S28). At this time, the jackpot effect symbol is stopped and displayed on the liquid crystal display unit 4. On the other hand, if the result of the jackpot determination in steps S18 and S19 is out of place, the CPU 30 stops and displays the out-of-sequence symbol determined in step S22 on the special symbol display means 11 (step S28). At this time, the effect symbol for displacement is stopped and displayed on the liquid crystal display unit 4.

When the special symbol for jackpot is stopped and displayed on the special symbol display means 11 (YES in step S29), the special profit state is subsequently executed (step S38).
When the special symbol for jackpot displayed on the special symbol display means 11 is a probability variation symbol (YES in step S39), “1” is set in the probability variation flag 47 (step S40). On the other hand, when the special symbol for jackpot displayed on the special symbol display means 11 is not a probability variation symbol (that is, a non-probability variation symbol) (NO in step S39), “0” is set in the probability variation flag 47. (Step S41).

In this embodiment, regardless of the type of special symbol at the time of jackpot, M support games are always executed after the end of the special profit state. Therefore, “1” is set in the support game flag 48, and the value “M”, which is the number of times the support game is cut, is set in the support game rotation number counter 49 (step S42).
Then, the value of the probability variation flag 47 is referred again (step S43), and when the probability variation flag 47 is “1” (YES in step S43), “1” is set to the probability variation maintenance effect flag 60. (Step S44). On the other hand, if the probability variation flag 47 is “0” (NO in step S43), “0” is set in the probability variation maintenance effect flag 60 (step S45).

On the other hand, if the result of the jackpot determination in steps S18 and S19 is out of order, and the out-of-order symbol is stopped and displayed on the special symbol display means 11 in step S27 (NO in step S29), then, the internal state of the ball game machine 1 It is checked whether or not the support game can be continued when the support game is in progress (step S30).
Specifically, the value of the support game rotation number counter 49 is referred to (step S30). When the value of the support game rotation number counter 49 is “1” or more (NO in step S30), that is, when the support game is being played, the value of the support game rotation number counter 49 is decremented (−1) (step) S31). When the value of the support game rotation number counter 49 after decrementing in step S31 has reached “0” (YES in step S32), the CPU 30 sets the value of the support game flag 48 to “0” (step S33). ).

  Further, the value of the table switching counter 50 is referred to (step S34). When the value of the table switching counter 50 is “1” or more (NO in step S34), that is, the winning lottery is won during the probability variation game, but the special symbol N times (the number of waiting times) from the winning of the falling lottery When the execution of the symbol variation operation is not completed, the value of the table switching counter 50 is decremented (-1) (step S35). If the value of the table switching counter 50 after the decrement in step S35 has reached “0” (YES in step S36), the CPU 30 sets “0” in the probability variation maintenance effect flag 60 (step S37). .

  FIG. 14 is a timing chart showing an example of switching (changing) the reference variation pattern selection table in the probability variation game. Before the occurrence of the special profit state (the operation of the condition device starts), it is assumed that the internal state of the ball game machine 1 is when the probability variation game is not executed and when the support game is not executed. Then, consider the case where the probability variation game is executed (the probability variation function is activated) after the execution of the special profit state. In FIG. 14, prior to the end of the support game by executing the symbol variation operation of M special (M rotations), when falling from the probability variation game by winning the falling lottery, more specifically, from the probability variation game An example is given of a case where the support game ends after the end of the execution of the symbol change operation of the special symbol N times (N rotations) after the fall.

  Before the occurrence of the special profit state, the reference variation pattern selection table is set from the fourth selection table group 32D. Therefore, the variation pattern lottery is executed using the predetermined fourth variation pattern selection table 33D. ing. After the special profit state is completed, both the probability variation game and the support game are executed (the probability variation function and the support function operate). As a result, the reference variation pattern selection table is switched from the variation pattern selection table included in the fourth selection table group 32D to the variation pattern selection table included in the first selection table group 32A. In the subsequent variation pattern lottery, a predetermined first variation pattern selection table 33A is used. The first variation pattern selection table 33A is used in the variation pattern lottery for a while not only while the probability variation game is being executed but also after falling down from the probability variation game.

  Then, when the symbol variation operation of the special symbol N times (N rotations) has elapsed since falling from the probability variation game, the variation pattern selection table for reference is changed from the variation pattern selection table included in the first selection table group 32A. It is switched to the variation pattern selection table included in the second selection table group 32B. In the subsequent variation pattern lottery, a predetermined second variation pattern selection table 33B is used.

  The symbol variation operation of the effect symbol based on the variation pattern selected and determined in the second variation pattern selection lottery is compared with the symbol variation operation of the effect symbol based on the variation pattern selected and determined in the first variation pattern selection lottery. Therefore, the time required for the symbol variation operation is relatively long, and the frequency of reach is high. In addition, in the production mode based on the variation pattern selected in the second variation pattern selection lottery, unlike the production mode based on the variation pattern selected in the first variation pattern selection lottery, the fall in relation to the symbol variation operation of the production symbol Messages can be displayed. Therefore, the player grasps the change of the reference variation pattern selection table by increasing the time required for the symbol variation operation of the production symbol, increasing the frequency of reach, and falling messages. can do.

  After that, when the symbol variation operation of the special symbol M times (M rotations) from the start of the support game is executed, the variation pattern selection table for reference is changed from the variation pattern selection table included in the second selection table group 32B. It is switched to the variation pattern selection table included in the 4 selection table group 32D. In the subsequent variation pattern lottery, a predetermined fourth variation pattern selection table 33D is used.

  FIG. 15 is a timing chart showing another example of switching (changing) the reference variation pattern selection table in the probability variation game. The timing chart shown in FIG. 15 is different from the timing chart shown in FIG. 14 in that the support game is executed after the fall from the probability variation game and before the symbol variation operation of the special symbol N times (N rotations) is finished. It is a point to end. In FIG. 15, it is the same as in the case of FIG. 14 that the player falls from the probability varying game by winning the falling lottery prior to the end of the support game.

  Before the occurrence of the special profit state, the reference variation pattern selection table is set from the fourth selection table group 32D. Therefore, the variation pattern lottery is executed using the predetermined fourth variation pattern selection table 33D. ing. After the special profit state is completed, both the probability variation game and the support game are executed (the probability variation function and the support function operate). As a result, the reference variation pattern selection table is switched from the variation pattern selection table included in the fourth selection table group 32D to the variation pattern selection table included in the first selection table group 32A. In the subsequent variation pattern lottery, a predetermined first variation pattern selection table 33A is used. The first variation pattern selection table 33A is used in the variation pattern lottery for a while not only while the probability variation game is being executed but also after falling down from the probability variation game.

  Then, when the symbol variation operation of special symbols M times (M rotations) has elapsed since the start of the support game, the variation pattern selection table for reference is selected from the variation pattern selection table included in the first selection table group 32A. It is switched to the variation pattern selection table included in the table group 32C. In the subsequent variation pattern lottery, a predetermined third variation pattern selection table 33C is used.

  After that, when the symbol variation operation of the special symbol N times (N rotations) is executed after falling from the probability variation game, the variation pattern selection table for reference includes the variation pattern selection table for reference included in the third selection table group 32C. To the change pattern selection table included in the fourth game selection table group 32D. In the subsequent variation pattern lottery, a predetermined fourth variation pattern selection table 33D is used.

  The symbol variation operation of the effect symbol based on the variation pattern selected and determined in the fourth variation pattern selection lottery is compared with the symbol variation operation of the effect symbol based on the variation pattern selected and determined in the third variation pattern selection lottery. Therefore, the time required for the symbol variation operation is relatively long, and the frequency of reach is high. In addition, in the production mode based on the variation pattern selected in the fourth variation pattern selection lottery, unlike the production mode based on the variation pattern selected in the third variation pattern selection lottery, the fall in relation to the symbol variation operation of the production symbol Messages can be displayed. Therefore, the player grasps the change of the reference variation pattern selection table by increasing the time required for the symbol variation operation of the production symbol, increasing the frequency of reach, and falling messages. can do.

FIG. 16 is a timing chart showing still another example of switching (changing) of the reference variation pattern selection table in the probability variation game. The timing chart shown in FIG. 16 differs from the timing charts shown in FIG. 14 and FIG. 15 in that it falls from the probability variation game after the end of the support game.
Before the occurrence of the special profit state, the reference variation pattern selection table is set from the fourth selection table group 32D. Therefore, the variation pattern lottery is executed using the predetermined fourth variation pattern selection table 33D. ing. After the special profit state is completed, both the probability variation game and the support game are executed (the probability variation function and the support function operate). As a result, the reference variation pattern selection table is switched from the variation pattern selection table included in the fourth selection table group 32D to the variation pattern selection table included in the first selection table group 32A. In the subsequent variation pattern lottery, a predetermined first variation pattern selection table 33A is used.

  Then, when the symbol variation operation of special symbols M times (M rotations) has elapsed since the start of the support game, the variation pattern selection table for reference is selected from the variation pattern selection table included in the first selection table group 32A. It is switched to the variation pattern selection table included in the table group 32C. In the subsequent variation pattern lottery, a predetermined third variation pattern selection table 33C is used. The third variation pattern selection table 33C is used in the variation pattern lottery not only during the execution of the probability variation game but also for a while after winning the fall lottery and falling from the probability variation game.

  After that, after winning the falling lottery and falling from the probability variation game, when the symbol variation operation of the special symbol N times (N rotations) is executed, the variation pattern selection table for reference becomes the third selection table group 32C. The change pattern selection table included is switched to the change pattern selection table included in the fourth selection table group 32D. In the subsequent variation pattern lottery, a predetermined fourth variation pattern selection table 33D is used.

  As described above, according to this embodiment, during the probability variation game, the variation pattern is selected and determined using the first variation pattern selection table 33A or the third variation pattern selection table 33C. Then, when the falling lottery is won and the execution of the symbol variation operation N times (the number of standby times) after the probability variation game is terminated, the second variation pattern selection table 33B or the fourth variation pattern selection table 33D is entered. Be changed. Due to such changes in the variation pattern selection tables 33A to 33D, the time required for the symbol variation operation of the effect symbols becomes longer, the reach appearance frequency becomes higher, or a fall message appears. Thereby, the player can grasp the change of the reference variation pattern selection table. Therefore, the player can be notified or suggested of a fall from the probability variation game.

Further, since the change timing of the reference variation pattern selection table is deviated from the winning timing of the falling lottery, the falling timing from the probability variation game can be blurred to the player. Thereby, the player can be kept in the ball game machine 1 even after falling from the probability-changing game, and therefore the player can be prevented from being separated at the time of falling.
As mentioned above, although one Embodiment of this invention was described, this invention can be implemented also with another form.

  In the above-described embodiment, it has been described that the predetermined number (N times) is predetermined as the number of standby times. However, the number of standby times may be determined by lottery by the number of standby times executed by the CPU 30 of the main control board 20. This waiting number lottery may be executed (one time) in relation to the entry of the probability variation game, or may be executed in relation to the winning of the falling lottery (one time). Good.

  In addition, as a fall effect, an example was given in which a fall message appeared during the symbol movement operation of the effect symbol, but the mode of the fall effect is not limited to this, and it is maintained with certainty instead of the fall message / in place of the fall message. A premium reach that does not appear in the production may appear, or a notice by a premium character that does not appear in the probability variation maintenance production may appear. Furthermore, the background image of the liquid crystal display unit 4 in the fall effect may be different from that in the probability change maintenance effect.

  The average fluctuation time β (sec) of the second fluctuation pattern selection lottery may be approximately the same as the average fluctuation time α (sec) of the first fluctuation pattern selection lottery, or shorter than the average fluctuation time α (sec). (Β ≦ α). However, when the average fluctuation time α (sec) is equal to the average fluctuation time β (sec), in order to notify or suggest a fall from the probability fluctuation game, at the time of execution of the second fluctuation pattern selection lottery A fall message, the premium character (for example, U), the premium reach (for example, J reach), etc. must appear.

  The average variation time δ (sec) of the fourth variation pattern selection lottery may be approximately the same as the average variation time γ (sec) of the third variation pattern selection lottery, or shorter than the average variation time γ (sec). (Δ ≦ γ). However, when the average variation time γ (sec) and the average variation time δ (sec) are approximately the same, in order to notify or suggest a fall from the probability variation game, at the time of execution of the fourth variation pattern selection lottery A fall message, the premium character (for example, U), the premium reach (for example, J reach), etc. must appear.

Moreover, the production | presentation aspect selection table 37 shown in FIGS. 5-8 is an example, and it cannot be overemphasized that the optimal content can be suitably set according to the type of the reach and notice prepared for the ball game machine 1.
Further, in the above-described embodiment, whether or not to notify (suggest) of the falling lottery is determined by what variation pattern is selected and determined on the main control board 20. That is, whether or not the falling lottery notification (implying) can be executed is determined by the main control board 20. However, whether or not the falling lottery notification (implying) can be executed can be determined by the effect control board 22.

The production mode selection table 37 shown in FIGS. 5 to 8 is merely an example, and it is needless to say that the optimum content can be appropriately set according to the reach and the type of notice provided in the ball game machine 1.
Further, in the above-described embodiment, the bullet ball game machine 1 in which only the support game with a limited number of times is prepared as the support game is taken as an example. However, not only the support game of the number of times as the support game, but also the support game (hereinafter referred to as “support game until the next time”) that is continuously executed until the next jackpot is established is combined with the ball game machine 1. It can also be provided. In this case, for example, the type of special symbol for jackpot displayed on the special symbol display means 11 when the jackpot is established and the type of support game (whether it is a support game with several cuts or a support game until the next time) are mutually It is associated.

  In the above-described embodiment, a plurality of types of support games may be prepared in the ball game machine 1, and any one of these support games may be selectively executed. These multiple types of support games are different from each other in the number of special symbol variation operations (number of times of cutting). In this case, the type of support game to be selected is associated with the type of special symbol for jackpot displayed on the special symbol display means 11 when the jackpot is established.

In addition, the generation of the support game and the generation of the probability variation game can be made independent from each other. Specifically, the probability variation game can be generated regardless of whether or not the support game is being played, and the support game can be generated regardless of whether or not the probability variation game is being played.
The present invention can also be applied to the ball game machine 1 in which the support game is subordinate to the probability variation game. In this case, the support game is generated regardless of whether or not the game is in a probability variation game, and is ended regardless of whether or not the game is in a probability variation game. In this case, there are only two internal states of the ball game machine 1: a state in which the probability variation game is being performed and the support game is being performed, and a state in which the probability variation game is not being performed and the support game is not being performed. Absent.

  In addition, during the execution of the above-mentioned support game, compared with the non-execution of the support game, the normal symbol display time on the normal symbol display means 12 is shortened, the winning probability of the normal symbol lottery is reduced, and The degree of expansion of the electric tulip accessory 8 at the time of winning the symbol lottery is increased. However, it is not necessary for the support game to perform all three, and it is sufficient that at least one of them is performed.

  In addition, the probability variation game prepared in the ball and ball game machine 1 can be a probability variation game with a number of cuts set with a predetermined number of symbol variation operations. In this case, a predetermined number of symbol variation operations are executed from the start of the probability variation game (that is, after the end of the special profit state), or are continuously executed until a falling lottery is won or a jackpot is established. Is. Even if a predetermined number of special symbol variation operations are executed in the probability variation game, if the jackpot is not established and the falling lottery is not won, the execution of the probability variation game is terminated and the ball game machine 1 The internal state of becomes a non-execution of the probability variation game.

  In addition, the configuration in which only one special symbol start port 7 is provided on the board surface of the game board 2 has been described as an example, but a plurality of special symbol start ports are provided on the board surface of the game board 2. Also good. In this case, a predetermined number of prize balls are paid out as the game balls enter the special symbol starting ports, and the big hit lottery is executed and the falling lottery is executed. In addition, as the game ball enters each special symbol start opening, the special symbol display operation in the special symbol display means 11 is executed, and after the symbol variation operation is finished, the special symbol for jackpot or the off symbol Is displayed on the special symbol display means 11.

  In addition, various design changes can be made within the scope of matters described in the claims.
