A game board on which a ball game in which the progress of the game is determined based on the flow-down mode of the game ball, and
Image data storage means in which the effect image is stored as image data;
Unit game control means for reading out the image data of the design image from the image data storage means, and performing the unit game with the image display means in a single process from the time when the design image is variably displayed to the time of stop display; ,
A game lottery means for determining, as a lottery result, whether or not to shift the ball game to a special game advantageous to a player;
Symbol information determination means for determining one symbol information from a plurality of symbol information determined for the symbol type based on the lottery result;
A symbol image stop display mode storage means in which a plurality of symbol image stop display modes are stored corresponding to each of the plurality of symbol information, as a display mode of a symbol image that is stopped and displayed in one unit game,
Stop display mode selection means for selecting one symbol image stop display mode from the plurality of symbol image stop display modes based on the symbol information, and the progress of the unit game based on a lottery result by the game lottery unit is predetermined. In the case where the above condition is not satisfied, one symbol image stop display mode corresponding to the symbol information is selected, and the progress of the unit game based on the lottery result by the game lottery means satisfies a predetermined condition Includes a stop display mode selection unit that selects one symbol image stop display mode that does not correspond to the symbol information.

  In this way, when the progress of the unit game satisfies a predetermined condition, one symbol image stop display mode that does not correspond to the symbol information is selected, so that the symbol image stop display mode that is originally selected is different. Since it is selected, it is possible to easily determine whether or not the game can be continued without complicating the configuration of the ball game machine, and the game can be continued. The possibility of increasing the joy of the player arises.

  Here, the variation display of the symbol image displays the symbol image in such a manner that the identification information constituting the symbol image is sequentially changed, or the symbol image is displayed in such a manner that the display position of the symbol image is changed. Display method. The time when the variable display of the symbol image is started is when the unit game is started. The variably displayed symbol image is stopped and displayed after a predetermined time has elapsed. In the stop display of the symbol image, certain identification information is displayed at a certain position of the image display means. Note that the stop display mode includes a mode in which the image display unit is finely moved or rocked about a certain position of the image display means. Anything can be displayed as long as it can be displayed.

  In addition, the “plurality of symbol information defined for the symbol type” means not only information on the symbol type itself but also information derived by the symbol type, for example, information on the type of progress of unit games such as reach, Contains information on the type of game result such as hit or miss.

  Furthermore, the “design image stop display mode” includes not only the design itself of the symbol image that has been stopped, but also the display mode of the design image. For example, it includes a display attribute of a symbol such as an array of a plurality of symbol images stopped and displayed, and a size and a color of the symbol image itself.

  Furthermore, “a plurality of symbol image stop display modes are stored corresponding to each of the plurality of symbol information” means that “a plurality of symbol image stop display modes” and “a plurality of symbol image stop display modes” This includes not only the case where each is stored in one-to-one correspondence but also the case where it is stored as many-to-one or one-to-many. Any design image stop display mode may be used as long as one symbol information is determined. For example, a plurality of symbol image stop display modes are first provided for one symbol information. A configuration may be adopted in which one symbol image stop display mode is finally determined by lottery processing.

  In addition, one symbol information is determined based on the lottery result from a plurality of symbol information, and based on the symbol information determined based on the lottery result, “from one symbol image stop display mode to one symbol image stop display mode. "select. For this reason, for example, in the case of a configuration in which “one symbol image stop display mode” is defined as a specific symbol image stop display mode, this specific symbol image stop display mode is accidentally caused by a lottery process. In some cases, symbol information corresponding to is defined. In consideration of such a case, it is preferable that the “predetermined condition” also includes a condition “when symbol information corresponding to one specific symbol image stop display mode is not determined by lottery processing”.

Furthermore, the plurality of symbol image stop display modes are:
A plurality of special symbol image stop display modes in which one can be selected as a display mode of a symbol image that is stopped and displayed in one unit game when it is determined that the game lottery means shifts to the special game. ,
A plurality of general symbol image stop display modes in which one can be selected as a display mode of a symbol image that is stopped and displayed in one unit game when it is determined that the game lottery means does not shift to the special game. It is preferable to contain.

  In this case, when the progress of the unit game based on the lottery result by the game lottery means does not satisfy the predetermined condition, the stop display mode selection unit selects among the plurality of special symbol image stop display modes. When one of the symbols corresponding to the symbol information is selected and the progress of the unit game based on the lottery result by the game lottery means satisfies the predetermined condition, the plurality of special symbol image stop display modes are displayed. It is desirable to select one that does not correspond to the symbol information.

  Further, the probability that the display mode of the symbol image that is stopped and displayed in one unit game becomes the special symbol image stop display mode is changed from a predetermined normal probability to a higher probability that is higher than the predetermined normal probability. And a probability variation transfer means for shifting the unit game to a probability variation state, and

The plurality of special symbol image stop display modes include a plurality of specific symbol image stop display modes capable of shifting the unit game to the probability variation state, and

When the main control circuit 50 (shown in FIG. 2) determines that the hit ball has won any of the above-described winning openings 32 to 38 and 39a to 39d, the main control circuit 50 (shown in FIG. 2) performs payout control. A control command is issued to a circuit (not shown). A payout motor (not shown) is electrically connected to the payout control circuit, and the payout control circuit that has received the control command is based on information indicating the number of prize balls included in the control command. A drive signal is issued to the payout motor. When the payout motor is driven, the prize balls are delivered to the tray 18 while counting the number of prize balls to be paid out.

<Image display device 30>
As described above, the image display device 30 is provided in a substantially central portion of the game area 28. As will be described later, various images such as a pattern image and a character image are displayed as effect images on the image display device 30. In the image display device 30, a game based on a graphic image, that is, a graphic image game simulating a slot game performed in a so-called slot machine is executed.

  The symbol includes identification information for indicating the result of the symbol image game, for example, identification information such as numbers such as “0”, “1” to “9”, and other characters and patterns. The symbol image is an image displayed on the image display device 30 so that this identification information can be visually recognized by the player. The image of the symbol is variably displayed or stopped on the image display device 30 by the image control circuit 52 described later. The variation display of the symbol image is displayed in such a manner that the identification information constituting the symbol image is sequentially changed, or the display position of the symbol image or the size or color of the symbol image is changed. This is a display method in which an image display mode is changed. The time when the symbol image variation display is started is the time when the symbol image game is started. The variably displayed symbol image is stopped and displayed by the image control circuit 52 after a predetermined time has elapsed. The stop display of the symbol image is a display mode that allows the player to visually recognize certain identification information at a certain position of the image display device 30. In particular, among the symbol image games, a period from when the symbol image is variably displayed until it is stopped is referred to as a unit game.

  The image display device 30 displays not only a symbol image but also a character image and a background image for enhancing the effect of the symbol image game.

<Starting prize opening 32>
When a hit ball is won at the start winning port 32 of the above-described winning ports 32 to 38 and 39a to 39d, the image of the symbol displayed on the image display device 30 starts to be changed, and a predetermined moving image or symbol is displayed. After the image is displayed for a predetermined time in a changing manner, the design image is stopped and displayed. That is, one unit game is started every time one hit ball wins the start winning opening 32. As will be described later, when a hit is won in the start winning opening 32 when a unit game is being performed in the image display device 30, the predetermined number, for example, four, is held. When the winning to the start winning opening 32 is held, when one unit game is finished, the next unit game is started based on the holding.

  When the symbol image is stopped and displayed, if the symbol image displayed on the image display device 30 has a specific aspect, the symbol image game is a so-called jackpot. For example, if three images of three symbols are displayed on the image display device 30 and all of the three symbols that are stopped and displayed after the variable display become so-called rough eyes, the symbol image game is a big hit. When the symbol image game is a big hit, the ball game is shifted to a special game. When the game is shifted to the special game, a predetermined demo image is displayed on the image display device 30 and the special winning opening 34 is opened to make the game ball easy to win, and the game ball flows into the special winning opening 34. It becomes easy to do. In this way, by winning the symbol image game, the ball game is shifted to a special game advantageous to the player.

  Two movable pieces 33a and 33b are provided in the vicinity of the left and right sides of the start winning opening 32 so as to be operable. When the game ball passes through the above-described normal symbol variation display ports 36 and 38, the normal symbol game is started in the normal symbol display unit 31 provided on the left side of the game board 24. When the game result of the normal symbol game is a win, the two movable pieces 33a and 33b are opened for a predetermined time so that the game ball can easily win the start winning opening 32. The normal symbol display unit 31 shown in FIG. 1 includes two lamps. When the game ball passes through the normal symbol variation display ports 36 and 38, the two lamps start blinking. After that, only one of the lights is turned on after a predetermined time has elapsed, and a normal symbol game is decided or missed by the lighted lamp.

<Special prize opening 34>
As described above, when the symbol image game in the image display device 30 is a big hit, the ball game is shifted to the special game, and the special winning opening 34 is opened to make it easy to win the ball. The easy winning state of the special winning opening 34 is, for example, 30 seconds until a predetermined number of hit balls are won in the special winning opening 34, for example, ten pieces are won, or until a predetermined time elapses after the special winning opening 34 is opened. Continue until it has passed. Thereafter, the special winning opening 34 is closed to make it difficult to win. A special area (not shown) is provided on the back of the special prize opening 34. The fact that the hit ball has passed through the specific area while the special winning opening 34 is opened is a condition for opening the special winning opening 34 again. That is, when a hit ball passes through a specific area while the special winning opening 34 is open, the special winning opening 34 is temporarily closed after a predetermined time, and then opened again to make it easy to win. The operation of opening and closing the special prize opening 34 is repeated a plurality of times, for example, 15 times, and then the special prize opening 34 is closed. A game from when the special winning opening 34 is opened until it is closed next is referred to as a single special game, and the number of times a single special game is played is referred to as the number of rounds.

<< Function in Pachinko machine 10 >>
FIG. 3 is a functional block diagram showing an outline of main control functions in the pachinko gaming machine 10.

  As shown in FIG. 3, the pachinko gaming machine 10 includes a control unit 500, a winning detection unit 400, and an effect unit 300. The control means 500 is electrically connected to the winning detection means 400 and the rendering means 300, and a winning detection signal emitted from the winning detection means 400 is transmitted to the control means 500. Further, the control signal issued from the control means 500 is transmitted to the effect means 300.

<Winning detection means 400>
The winning detection means 400 detects whether or not the game ball moving on the game board has won a predetermined winning opening. For example, it is detected whether or not a game ball has won any of the winning openings 32 to 38 and 39a to 39d. The winning detection means 400 includes a winning detection sensor group 70 that generates a detection signal when it detects the passage of a game ball that has won a winning opening. The winning detection sensor group 70 is preferably a winning detection sensor that is provided in the flow path of the game ball formed behind each of the above-described winning ports 32 to 38 and 39a to 39d and detects the passage of the game ball.

<Control means 500>
The control unit 500 includes a main control unit 510 and a sub control unit 610. The main control unit 510 and the sub control unit 610 are electrically connected to each other, and a control command issued from the main control unit 510 is sent to the sub control unit 610.

The main control means 510 is preferably composed of the main control circuit 50 described above.

<Game lottery means 512>
The game lottery means 512 performs a lottery for winning or losing. Whether or not to shift to a special game, which will be described later, is determined by this hit or miss.

  The game lottery means 512 is extracted by, for example, a random number generating means (hardware random number) 514 for winning or losing lottery, a random number extracting means 516 for extracting random numbers generated by the random number generating means, and a random number extracting means 516. Random number judging means (symbol information determining means) 518 for judging the presence / absence of winning based on the random number value.

  The random number generation means 514 of the game lottery means 512 generates random numbers within a predetermined positive integer range (for example, 0 to 65535 in decimal notation). The random number extraction unit 516 extracts the random number generated by the random number generation unit at a predetermined timing. The random number determining means 518 determines whether the random value is hit or wrong according to the region to which the random value belongs, by comparing the random value extracted by the random number extracting means 516 with a lottery table (not shown).

  Note that the hit or miss determined by the random number determination means 518 includes information on the winning mode and the missing mode in the above-described symbol image game, and information on the symbol image to be stopped and displayed in the symbol image game. For example, in the case of losing, in addition to simply losing the symbol image game, various kinds of information such as information on the process of reaching the detachment, such as when the symbol image game is once reached and then released. Information on the mode of detachment and information on the pattern image to be finally stopped and displayed are also included. In addition, in the case of winning, in addition to the normal winning in which the symbol image game is simply a hit, the so-called probable change that shifts to the probability fluctuation state, or the symbol image game is once reached in the reach or super reach, and then wins. As in the case, information on various types of winning such as information on the type of winning and information on progress in the middle of reaching the winning, and information on the image of the symbol that is finally stopped and displayed are also included.

  The random number generation by the random number generation means 514 described above is executed in step S13 or S17 of FIG. The determination process by the random number determination unit 518 is executed in step S46 of FIG.

<Random number storage means 540>
The random number storage unit 540 includes a normal storage unit 542 and a holding area 544. The random number storage means 540 is preferably composed of the RAM of the main control circuit 50 described above. Both the normal storage unit 542 and the reserved area 544 store the value of the random number generated by the random number generation unit 514 described above.

<Normal storage unit 542>
The normal storage means 542 is a random number when a unit game is not executed in the image display means 330 when a game ball is won at the start winning opening 32 and all the reserved areas 544 described later are vacant. The random number value generated by the generating means 514 is stored. In this case, random number value storage processing is executed in step S14 of FIG. 4 described later, and random number value reading processing stored in the normal storage means 542 is executed in step S44 of FIG. 5 described later. The

<Reserved area 544>
The reserved area 544 includes a plurality of, for example, four storage areas. This reserved area 544 is generated by the random number generating means 514 when a unit game is executed in the image display means 330 and at least one storage area constituting the reserved area 544 is free. Stores the value of a random number. In the plurality of storage areas, priorities are determined. When the storage areas are composed of four storage areas, the first candidate storage area, the second candidate storage area, the third candidate storage area, And a fourth candidate storage area. The process of storing the random number value is executed in step S18 of FIG. 4 to be described later, and the process of reading the random number value stored in the holding area 544 is executed in step S48 of FIG. 5 to be described later.

  In the process of storing the random number value in the reserved area 544, the storage areas are used in order from the storage area with the highest priority among the plurality of storage areas. When no random number value is stored in any storage area of the reserved area 544, the random number value is stored in the storage area with the highest priority. For example, in the case of four storage areas, if no random number value is stored in any of the four storage areas, the random number value is stored in the first candidate storage area. Further, when the random number value is already stored in the first candidate storage area, the random number value is stored in the second candidate storage area. In this way, random values are sequentially stored up to the fourth candidate storage area.

  In addition, the process of reading the random number value from the reserved area 544 is always read from the storage area with the highest priority regardless of the number of storage areas in which the random number value is stored. In the case of the four storage areas described above, data is always read from the first candidate storage area. After the random number value is read from the storage area with the highest priority, the storage area is cleared. Next, when a random number value is stored in the storage area with the next highest priority, the random number value is stored again in the storage area with the highest priority. In this way, the random number value is re-stored in the storage area having one higher priority until reaching the storage area in which the random number value is not stored.

  For example, when the reserved area 544 includes four storage areas, the random number value in the first candidate storage area is read, and then the first candidate storage area is cleared. Furthermore, when the random number value is stored after the second candidate storage area, the random number value is stored again in the storage area having one higher priority. That is, after the random number value is read from the first candidate storage area, if the random number value is also stored in the second candidate storage area, the random number value stored in the second candidate storage area Are stored again in the first candidate storage area. When the random number value is also stored in the third candidate storage area, the random number value stored in the third candidate storage area is stored again in the second candidate storage area.

<< Control processing >>
Hereinafter, various controls performed in the main control unit 510 and the sub control unit 610 described above will be described. In the following, the pachinko gaming machine 10 has been activated in advance, and the above-described main control means 510 and sub-control means 610 have finished the activation processing such as initialization of various variables used for control, and the pachinko gaming machine 10 10 is assumed to be in steady operation.

  4 and 5 described below show a subroutine executed by the main control unit 510, and FIGS. 6 and 7 show a subroutine executed by the sub control unit 610. Note that the flowcharts shown in FIGS. 4 to 7 show only one example for executing the control process in the main control unit 510 or the sub control unit 610 as long as the same process can be performed. The procedure is not limited to those shown in these flowcharts.

<Winning process>
FIG. 4 is a flowchart showing a winning process subroutine executed by the main control means 510. The subroutine shown in FIG. 4 is called from a main program (not shown) executed in advance by the main control means 510 at every predetermined timing and repeatedly executed.

  First, it is determined whether or not the game ball moving on the surface of the game board 24 has won the start winning opening 32 (step S11). As described above, the start winning opening 32 is provided with a winning detection sensor (not shown) that detects that a game ball has passed and issues a detection signal to the main control means 510. The process of step S11 is determined based on whether or not the above-described winning determination processing unit 530 has transmitted a detection signal from the winning detection sensor to the main control unit 510.

  When it is determined in step S11 that the game ball has won the start winning opening 32, it is determined whether or not the image of the symbol is being variably displayed on the image display means 330 (step S12). This determination is made based on the time when the time measurement is started with reference to the time when the determination result determined by the random number determination means 518 is transmitted to the sub-control means 610 in step S47 of FIG. As shown in FIG. 6 described later, the sub-control unit 610 starts to display the variation of the symbol image when the determination result is received from the main control unit 510. Furthermore, the time during which the symbol image is variably displayed in the sub-control means 610 is determined according to the determination result determined in the determination process of step S46 of FIG. From this, the determination in step S12 described above is based on the determination result determined in step S46 of FIG. 5 and the time when the time measurement was started in step S47, and the image of the symbol is variably displayed on the image display means 330. The main control means 510 can determine whether or not it is in the middle.

  When it is determined in step S12 described above that the image of the symbol is not being displayed in the image display means 330, the random number generation means 514 obtains a random number (step S13), and the main control means stores the random number. The obtained random number value is stored in the normal storage means 542 previously assigned to the means 540 (step S14). Next, the value of the flag F_flow is set to 1 (step S15). This flag F_flow is a flag indicating whether or not a game ball has won the start winning opening 32 and the image of the symbol is not variably displayed on the image display means 330. The value of the flag F_flow is 1 when a game ball is won at the start winning opening 32 and the symbol image is not variably displayed on the image display means 330. On the other hand, the value of the flag F_flow is 0 when the game ball has not won the start winning opening 32 or when the image of the symbol is variably displayed on the image display means 330. The value of the flag F_flow is determined in step S43 in FIG.

  On the other hand, when it is determined in the above-described step S12 that the symbol image is being variably displayed on the image display means 330, the reserved area 544 allocated in advance to the random number storage means 540 of the main control means is empty. It is determined whether or not there is (step S16). As described above, the reserved area 544 includes a predetermined plurality, for example, four storage areas. When it is determined in step S16 that the reserved area 544 is empty, a random number is acquired (step S17), and the value of the random number is stored in the empty area of the reserved area 544 (step S18).

  Further, when it is determined in step S16 described above that there is no space in the reserved area 544, or when the process of step S15 or S18 is executed, the process proceeds to step S20 described later.

  By performing the above-described processing of steps S11 to S18, when a game ball is won at the start winning opening 32, if the image of the symbol is not variably displayed on the image display means 330, a random number is immediately obtained and the value is obtained. Is stored in the normal storage means 542. On the other hand, when a game ball is won at the start winning opening 32 and the image of the symbol is variably displayed on the image display means 330, if there is an empty space in the reserved area 544, the reserved area 544 is acquired. The random numbers are sequentially stored, and when the reserved area 544 is full, the fact that the game ball has won the start winning opening 32 is ignored.

  When it is determined in step S11 described above that the game ball has not won the start winning opening 32, it is determined whether or not the game ball has won the other winning openings 36, 38, etc. (step S19). When it is determined that no game ball has been won in other winning holes 36, 38, etc., this subroutine is immediately terminated.

  When it is determined in step S19 that a game ball has won in another winning opening 36 or 38, when it is determined in step S16 that there is no free space in the holding area 544, or the processing in step S15 or S18 described above is executed. After that, a process of paying out game balls to the tray 18 by the number corresponding to the type of the winning opening is executed (step S20), and this subroutine is finished.

<Judgment result transmission process>
FIG. 5 is a flowchart showing a subroutine of determination result transmission processing executed in the main control means 510. The subroutine shown in FIG. 5 is called from a main program (not shown) executed in advance by the main control means 510 at predetermined timings and repeatedly executed.

  First, it is determined whether or not the image of the symbol is being variably displayed on the image display means 330 (step S41). When it is determined that the symbol image is being variably displayed, this subroutine is immediately terminated.

  On the other hand, when the image display means 330 determines that the symbol image is not being variably displayed, it is determined whether or not a random number value is stored in the holding area 544 (step S42). When it is determined that the random number value is not stored in the reserved area 544, it is determined whether or not the value of the flag F_flow described above is 1 (step S43). When it is determined that the value of the flag F_flow is not 1, that is, when the image of the symbol is not variably displayed on the image display means 330 and the game ball is not won at the start winning opening 32, immediately This subroutine ends.

  When it is determined in step S43 described above that the value of the flag F_flow is 1, the random number value stored in the normal storage unit 542 is read (step S44), and the value of the flag F_flow is set to 0 (step S45). Next, the random number determination means 518 executes determination processing based on the random number value acquired in step S13 or S17 described above (step S46). This determination process is a process for determining whether or not the random number determination means 518 determines whether or not it is hit, and as described above, by comparing the value of the random number generated by the random number generation means 514 with a lottery table (not shown), Whether to win or fail is determined according to the area to which the random number value belongs. Note that, as described above, the winning or losing determined as the determination result by the random number determining means 518 includes various information related to the winning or losing pattern image game performed by the image display means 330.

  As will be described later, the determination result determined by the determination process in step S46 is transmitted to the sub-control means 610. When the determination result is transmitted from the main control unit 510, the sub-control unit 610 starts the variable display of the symbol image in the image display unit 330 and executes the unit game. In particular, when the determination result transmitted from the main control means is a win, the sub-control means 610 wins the unit game when the symbol image is started to change and the symbol image is stopped and displayed. . Thereafter, the sub-control means 610 executes a jackpot effect process in step S83 of FIG. 6 described later, while the main control means 510 shifts the ball game to the special game.

  In this way, when the determination result is a win, the main control unit 510 shifts the ball game to the special game, and the sub control unit 610 performs a big hit effect process in the image display unit 330. As described above, when the main control means 510 shifts the ball game to the special game, the special game port 34 is opened to make the game ball easy to win, and the game ball is changed to the special game port 34. A special game that facilitates inflow is performed. In this way, the ball game shifts to a special game that is advantageous to the player.

  After executing the determination process of step S46 described above, the determination result determined in the process of step S46 is transmitted to the sub-control means 610 (step S47), and this subroutine is terminated.

  When it is determined in step S42 described above that the random number value is stored in the reserved area 544, the random number value stored in the storage area having the highest priority among the plurality of reserved areas 544 is read ( Step S48). Next, the random number value remaining in the holding area 544 is shifted one by one to the storage area having a higher priority and stored again (step S49). That is, for example, when the reserved area 544 is composed of four storage areas, the random number value stored in the second candidate storage area is shifted to the first candidate storage area and stored in the third candidate storage area. The random number value is shifted to the second candidate storage area, and the random number value stored in the fourth candidate storage area is shifted to the third candidate storage area.

  After executing the process of step S49 described above, the process proceeds to step S46 described above, the same process as described above is executed, and this subroutine is terminated.

<Image display processing>
FIG. 6 shows a subroutine of image display processing executed in the sub-control means 610 described above. The subroutine shown in FIG. 6 is called from a main program (not shown) executed in advance by the sub-control means 610 at predetermined timings and repeatedly executed.

  First, the determination result issued from the main control means 510 is received (step S71). This process is a process corresponding to the process of step S47 of FIG. As described above, the determination result received in step S71 includes symbol information for determining the symbol when the image display unit 330 stops display.

  Next, a subroutine for processing for selecting image data of the pattern shown in FIG. 7 to be described later is called and executed based on the received determination result (step S72). By executing this subroutine, the graphic image data to be stopped and displayed in step S80 described later is selected.

  Next, the image data is read from the image data storage unit 670, and the display position on the image display unit 330 is determined (step S74). The image data is symbol image data, character image data, and background image data. The symbol image data is read from symbol image data storage means 672, and the character image data is read from character image data storage means 674. The background image data is read out from the background image data storage means 676. Next, the read design image data is written into the display data storage means 680 of the image display control means 660 and the design image is displayed on the image display means 330 (step S75), and the read background image data is subjected to image display control. The image is written in the display data storage means 680 of the means 660 and the background image is displayed on the image display means 330 (step S76), and the character image data read in step S74 is displayed as the display data storage means 680 of the image display control means 660. The character image is displayed on the image display means 330 (step S77). By repeatedly executing the processes of steps S74 to S77 described above, the image display means 330 displays the image of the design in a variable manner and displays an image in which the character performs a predetermined action.

  After executing the process of step S77 described above, it is determined whether or not it is time to stop and display the symbol image (step S79). When it is determined that it is time to stop and display the symbol image, one symbol image of the three symbol images is stopped and displayed (step S80). In step S80, the symbol image determined in the symbol image data selection process of FIG. 7 executed in step S72 is stopped and displayed.

In step S79 described above, when it is determined that it is not the timing to stop and display the symbol image, or when the processing of step S80 is executed, it is determined whether or not all the symbol images have been stopped and displayed (step S81). When it is determined that all the symbol images are not stopped and displayed, the process returns to step S74 described above.
On the other hand, if it is determined that all the images of the symbols have been stopped and displayed, they are received in step S71.

Based on the determination result, it is determined whether or not to make a big hit effect in the image display means 330 (step S82). When it is determined that the jackpot effect is made in the image display means 330, the jackpot effect process (not shown) is called and executed (step S83). When it is determined that the big hit effect is not performed in the image display means 330, or after the processing of step S83 is executed, this subroutine is finished.

<Design image data selection processing>
FIG. 7 is a flowchart showing a subroutine of processing for selecting symbol image data that is called and executed in step S72 shown in FIG.

  It is determined whether or not the determination result received in step S71 of FIG. 6 described above is out of step (step S91). When it is determined that the received determination result is not off, that is, when it is determined that the determination result is a win, it is further determined whether or not the received determination result is a positive hit (step S92).

  If it is determined in step S92 that the determination result received in step S71 is a probable hit, it is determined whether or not the value of the variable C_game is between 0 and 100 (step S93). This variable C_game is a variable indicating the number of unit games that have been played since the ball game machine was activated. In addition, when the number of unit games played since the ball game machine was started becomes 100 times or more, or the number of unit games played after the ball game machine is started is 100 times or less. When “7” is selected, the value of the variable C_game is “−1”.

  When it is determined in step S93 that the value of the variable C_game is 0 or more and 100 or less, the value of the variable C_game is set to −1 (step S94), and the value of the variable C_fail is set to 0 (step S95). This variable C_fail indicates the number of times that the determination result received in step S71 is continuously lost. Next, “7” is selected as a symbol to be stopped and displayed on the image display means 330, regardless of the type of symbol information included in the determination result received in step S71 (step S96). The symbol selected in step S96 is displayed as a symbol image to be stopped when the process in step S80 in FIG. 6 described above is executed.

  By executing Steps S92 to S96 described above, the determination result of the determination process performed by the main control means 510 when the number of unit games performed after the ball game machine is activated is 100 times or less. Is a probable hit, the image of the symbol “7” is stopped and displayed on the image display means 330 regardless of the symbol information included in the determination result.

  When it is determined in the process of step S93 that the value of the variable C_game is not greater than 0 and less than 100, that is, when the value of the variable C_game is less than 0 or greater than 100, It is determined whether the value of C_fail is 1000 or more (step S97). When it is determined that the value of the variable C_fail is 1000 or more, the processes of steps S95 and S96 described above are executed.

  By executing the processes of steps S92 to S93 and S95 to S97 described above, the main control means 510 performs the determination when the determination result received in step S71 is 1000 or more. If the determination result of the determined determination process is a probable hit, the image of the symbol “7” is stopped and displayed on the image display means 330 regardless of the symbol information included in the determination result. Will be.

  When it is determined that the value of the variable C_fail is less than 1000 in step S97 described above, or when it is determined that the determination result received in step S92 is not a positive change, the value of the variable C_fail is set to 0 (step S98). ). In this way, by setting the value of the variable C_fail to 0, the number of times that the image game is continuously lost after the image game has once been a big hit is indicated. That is, the variable C_fail indicates the number of unit games performed after it is determined to shift to the special game and is determined not to shift to the special game.

  If it is determined that the determination result received in step S91 is not out of the range, the value of the variable C_fail is increased by 1 (step S99).

  After executing the process of step S98 or S99 described above, a lottery process is performed based on the symbol information included in the determination result received in step S71 of FIG. 6 to select a symbol (step S100). Here, the selected symbol is displayed as an image of a symbol that is stopped and displayed when the process of step S80 in FIG. 6 described above is executed.

  After executing the process of step S96 or S100 described above, it is determined whether or not the value of the variable C_game is 0 or more and less than 100 (step S101). When it is determined in step S101 that the value of the variable C_game is 0 or more and less than 100, the value of the variable C_game is increased by 1 (step S102), and when the value of the variable C_game is determined to be less than 0, or 100 or more When it is determined that the variable C_game is determined, the value of the variable C_game is set to −1 (step S103), and this subroutine is terminated.

  In the subroutine of FIG. 7 described above, when it is determined in step S93 that the value of variable C_game is 0 or more and 100 or less, or when it is determined in step S97 that the value of variable C_fail is 1000 or more, step S96 is executed. Always select the symbol “7”.

  However, if the information regarding the symbol included in the determination result received in step S71 of FIG. 6 is already information indicating the symbol “7”, it is not necessary to select the symbol “7” in step S96. For this reason, it may be determined in step S92 of FIG. 7 whether or not the information regarding the symbol is a thing other than “7” of the symbol. By processing in this way, “if the progress of the unit game based on the lottery result by the game lottery means satisfies a predetermined condition, one symbol image stop display mode that does not correspond to the symbol information is selected. "You can always do that."
