  The VDP 161 reads the background of the display screen and various types of identification information from the image data ROM 162 based on an instruction from the display main control unit 150, develops this on the VRAM 163, and displays one screen worth to be displayed on the special symbol display device 30. Configure the display data. The VDP 161 has a function of sequentially reading out display data for one screen stored in the VRAM 163 according to a predetermined image timing signal and sending it to the special symbol display device 30.

  The voice control circuit 170 has a function of synthesizing a voice signal such as a sound effect according to an instruction received from the game control CPU 111 of the one-chip microcomputer 110 and outputting it to the speaker 175.

  The voice control circuit 170 has an I / O port 171 for sending and receiving various signals to and from the one-chip microcomputer 110, a voice synthesis circuit 172, and a voice amplification circuit 173. The voice synthesis circuit 172 is a circuit that synthesizes voice signal waveforms of various music and sound effects according to a control signal received through the I / O port 171. The audio amplification circuit 173 amplifies the audio signal synthesized by the audio synthesis circuit 172 and outputs the amplified audio signal to the speaker 175.

Next, the operation will be described.
FIG. 5 shows an operation when selecting the type of the identification information group. When a predetermined switching timing arrives (step S501; Y), the identification information group selection means 130 performs a random number lottery for selecting the identification information group (step S502), and selects the identification information group corresponding to the lottery result. Select (step S503). The setting changing unit 131 changes the predetermined setting content to a value corresponding to the identification information group selected by the identification information group selecting unit 130 (step S504). Then, the type of the selected identification information group and the new setting value are registered in a predetermined setting table.

  For example, when changing the probability that a jackpot appears in the random number lottery means 121 depending on the type of the identification information group, the jackpot probability is selected according to the type of the identification information group selected by the identification information group selection means 130, and the value is set. Register in the setting table. The values registered in the setting table are referred to when the random number lottery means 121 executes the random number lottery, and the random number lottery is executed so that a big hit comes out according to the registered probability.

  It should be noted that the switching timing of the identification information group may come every time a ball wins the start opening 50, or may come every time a display game is performed a predetermined number of times, for example.

  FIG. 6 shows a flow when the right to execute a display game is secured. When a ball, which is a game medium, wins in the starting port 50 (step S601; Y), the execution right management means 123 determines whether or not the current number of holds has reached the upper limit of four times (step S602). And when the number of reservations has already reached the upper limit (step S602; Y), the right to execute the display game based on the current winning is not secured.

  On the other hand, when the number of reservations has not reached the upper limit (step S602; N), “1” is added to the current number of reservations to secure (hold) the execution right (steps S603 and S604). Next, referring to the setting table, the type of the currently selected identification information group and the value of the set value are read (step S605).

  When changing the appearance probability of jackpot depending on the type of the identification information group, a random value lottery for determining the final execution result of the display game performed based on the execution right secured this time ( This indicates the jackpot appearance probability) (step S606). For example, the first identification information group 410 has a jackpot probability of 1/160, the second identification information group 430 has a jackpot probability of 1/280, and the third identification information group 450 has Random lottery is performed with a jackpot probability of 1/395.

  Whether or not the numerical value extracted by the random number lottery corresponds to the special prize is checked with reference to the jackpot determination reference table, and the execution result of the display game executed based on the execution right is obtained (step S607).

  Furthermore, the progress pattern corresponding to the execution result and the contents of the identification information constituting the final execution result (for example, a combination of identification information such as “777”, “BAR, BAR, and bell”) are selected by random lottery etc. (Step S608). Then, the type, setting value, game progress pattern, contents of the execution result, etc. of the previously read identification information group are stored in the memory (step S609).

  Next, the flow at the time of executing the display game based on the held execution right will be described with reference to FIG. If the number of holds for the display game is not 0 (step S701; Y), the execution right management means 123 subtracts the number of holds by “1” and turns off one lamp of the special symbol storage display device 30a (step S701). S702).

  The execution result of the display game stored in the memory, the type of identification information group used in the current display game, and the like are read (step S703), and a predetermined execution start command including the read information and a display game start instruction Is output to the display control CPU 180 of the display main control unit 150 through the I / O port 151. The one-chip microcomputer 110 measures the elapsed time from the time when the execution start command is output in order to synchronize the output timing of sound effects and the like with the display screen.

  Upon receiving the display game execution start command, the display control CPU 180 starts executing the display game using the specified identification information group (step S604). Thereby, the identification information starts to scroll from top to bottom for each column of the matrix. In the display game, as shown in FIG. 8, the identification information is scrolled from the top to the bottom in units of each column on the display area of the special symbol display device 30 divided into a matrix of 3 columns and 3 rows. Is displayed (FIG. 8a). In the figure, a downward arrow 801 is a simulation display of the state where the identification information is scrolling.

  After such scrolling display for a predetermined time, the scrolling speed gradually decreases, the scrolling operation stops in the order of the left column 31, the center column 32, the right column 33, etc. The identification information is stopped and displayed one by one. In the example of FIG. 8, a display game is executed using the second identification information group 430, and a reach state in which two numbers of “7” are aligned on the horizontal line in the middle appears in the middle, and in FIG. 777 "special prize display mode appears and is a big hit, and in FIG. FIG. 9 shows an example when the same display game of FIG. 8 is performed using the fourth identification information group 470.

  When the execution result of the display game is a special prize in which a special prize display mode appears (step S705; Y), the special prize opening 90 is opened and closed a predetermined number of times to give a special value (step S706). That is, every time a ball wins in the big winning opening 90, about 10 to 13 winning balls are paid out to the upper plate 20, so that by opening the big winning opening 90 and forming a state where the winning probability of the ball is high, A substantial number of balls will be given to the player.

  In addition, when changing the upper limit of the number of payout balls in the special prize state depending on the type of the identification information group, the upper and lower limit number of times of opening / closing the special winning opening 90 is changed. For example, in the case of the first identification information group 410, it is 10 times (round), in the case of the second identification information group 430, it is 14 times, and in the case of the third identification information group 450, it is 16 times. In the case of the group 470, it is 18 times.

  In this way, when a special prize appears in the display game and the special value imparting operation by opening and closing the special prize opening 90 is completed, a change request to the short-time mode is output from the special prize control means 122 to the operation mode switching means 128. (Step S707).

  FIG. 10 shows a flow of processing performed by the operation mode switching unit 128. When the special value giving operation (opening / closing operation of the big prize opening 90) based on the appearance of the special prize in the display game is completed and a request for changing to the time-saving mode is received from the special prize control means 122 (step S1001; Y), the operation The mode switching unit 128 switches the operation mode of the second display game to the time reduction mode (step S1002). Thereby, the time required to execute the second display game once is shortened to about 1-2 seconds.

  Simultaneously with the shift to the time reduction mode, the operation mode switching means 128 sets a reference value representing the number of second display games to be executed until the time reduction mode is canceled in the subtraction counter, and starts counting (step S1003, S1004). Here, the reference value set in the subtraction counter is changed according to the type of the identification information group used in the display game that has awarded the special prize. For example, it is set to 50 times for the first identification information group 410, 80 times for the second identification information group 430, 100 times for the third identification information group 450, and 120 times for the fourth identification information group 470. Etc.

  The count value of the subtraction counter is decremented by 1 each time the second display game is executed, and when it becomes 0 (step S1005; Y), the operation mode is returned from the time reduction mode to the normal mode (step S1006). .

  Note that if the number of continuations of the time reduction mode is not changed depending on the type of identification information group, a predetermined constant number of continuations may be set in the subtraction counter in step S1004.

  FIG. 11 shows a flow when the right to execute the second display game is secured. When the ball passes through the left gate 71 or the right gate 72 as the game condition change detection unit (step S1101; Y), the execution right management unit 123 sets the number of suspensions for the second display game at the present time to an upper limit of 4 times. It is determined whether or not it has been reached (step S1102). And when the number of pending | holdings has already reached the upper limit (step S1102; Y), the execution right of the 2nd display game based on this prize is not ensured.

  On the other hand, when the number of holdings has not reached the upper limit (step S1102; N), “1” is added to the number of holdings for the current second display game to secure (hold) the execution right (steps S1103, S1104). ). Further, a random number lottery for determining the final execution result of the second display game performed based on the secured execution right is performed (step S1105). Whether or not the numerical value extracted in the random number lottery corresponds to the winning is checked with reference to the winning determination reference table, and the execution result of the second display game executed based on the execution right is obtained (step S1106). This is stored in the memory (step S1107).

  FIG. 12 shows a flow when the second display game is executed based on the execution right being held. If the number of holds for the second display game is not 0 (step S1201; Y), the number of holds is decremented by “1” and one lamp of the normal symbol memory display device 40a is turned off (step S1202). Next, the execution result of the second display game stored in the memory is read (step S1203), and the second display game is executed so that the execution result according to the execution result appears (step S1204).

  At this time, if the operation mode is the normal mode, the display content of the normal symbol display device 40 is changed for 10 to 15 seconds, and then the final execution result is stopped and displayed. On the other hand, when the operation mode is set to the time reduction mode, the execution result is stopped and displayed after a fluctuation period of 1 to 2 seconds. Thereafter, the count value of the subtraction counter that counts the number of executions of the second display game in the time reduction mode is decremented by 1 (step S1205). When the count value of the subtraction counter becomes 0 during the time reduction mode, the time reduction mode is canceled.

  When “7” is stopped and displayed in the second display game (step S1206; Y), the condition device 51 of the starting port 50 is opened until the closing condition is satisfied (steps S1207 to S1209). Here, the condition device 51 is closed in about 2 seconds or closed when one ball wins the starting port 50.

  In the embodiment described above, depending on the type of the identification information group, the jackpot probability is changed or the number of prize balls in the special prize state (that is, the upper limit number of times for opening and closing the big prize opening 90) is changed. Only one of these may be changed according to the type of the identification information group, or both may be changed according to the type of the identification information group.

  Also, when the execution result of the display game is in a specific display mode, until the predetermined release condition is satisfied after the next time, a probability variation state in which the probability that the special prize display mode appears in the display game is higher than normal is entered. In the above configuration, how much the probability is increased in the probability variation state may be changed according to the type of the identification information group used in the display game that has caused the probability variation state.

  For example, in the first identification information group 410, when the identification information (probability variation) of “BAR” is gathered and a special prize display mode is set, or in the second identification information group 430, “3”, “5” The probability variation state is entered when the probability variation patterns of “7” are gathered and the special prize display mode is obtained. In the display game using the first identification information group 410, when “BAR” (probability variation pattern) appears and the probability variation state is entered, the probability of winning in the random number lottery performed by the random number lottery means 121 is set to 80 minutes. For example, when a probability pattern such as “3” appears in the display game using the second identification information group 430 and the probability variation state is entered, the value is set to 1/50.

  Further, the number of times the probability variation state is continued may be changed according to the type of the identification information group used in the display game that causes the probability variation state. Of course, both the winning probability and the number of continuations in the probability variation state may be changed according to the type of the identification information group used in the display game that caused the probability variation state.

  In addition, the setting contents to be changed according to the type of the identification information group include the probability of winning in the random number lottery in the random number lottery means 121, the number of times of opening / closing the big prize opening 90 at the time of the special prize, the number of times of the short time mode, the probability variation You may combine suitably the winning probability in a state, the frequency | count of a probability fluctuation state, etc.

  In the embodiment, the number of identification information constituting each identification information group is made different according to the type of identification information group. However, the number of identification information belonging to one identification information group may be unified. In the embodiment, the smaller the number of pieces of identification information belonging to the identification information group, the higher the jackpot probability and the number of winning balls. However, the higher the jackpot probability, the higher the number of winning balls may be combined. Good.

  Further, in the embodiment, the timing for selecting the type of the identification information group is set every time the display game is executed or every predetermined number of times, but other timings may be used. For example, you may select every fixed time or every random time.

  Note that the contents to be changed according to the type of the identification information group are not limited to those shown in the embodiment as long as the conditions are related to the progress of the game. For example, the number of prize balls to be paid out may be changed according to the winning of one ball.
