  Next, the operation of the embodiment configured as described above will be described. A game is started when a power switch (not shown) is turned on and the player inserts a game ball into the storage tray 30 and operates the operation handle 42. The control circuit 61 starts execution of the winning ball processing program shown in FIG. 7 at step 100, initializes various variables at step 101, and whether the game ball has entered the winning hole 12 at step 102. Determine whether or not. If the game ball has not entered the winning opening 12, the program proceeds to step 104 under the determination of "NO" in step 102, and the following steps are executed. When the game ball enters the winning opening 12, the program proceeds to step 103 under the determination of "YES" in step 102, a winning signal is output, and the prize ball supply solenoid is driven by the drive circuit 51a. 51 is excited to rotate the claw wheel to supply a predetermined number of prize balls to the storage tray 30. Then, in step 104, it is determined whether or not a game ball has entered the first type starting port 13. When the game ball has not entered the first type start port 13, the program proceeds to step 102 under the determination of "NO" in step 104, and steps 102 to 104 are executed thereafter. When a game ball enters the first type starting port 13, the program proceeds to step 105 under the determination of "YES" in step 104, and a winning signal is output. The prize ball supply solenoid 51 is excited by driving the drive circuit 51 a in response to the winning signal, and the hook wheel is rotated to supply a predetermined number of prize balls to the storage tray 30 through the prize ball supply basket 52.
[0019]
  On the other hand, the control circuit 61 starts the execution of the display program shown in FIGS. 8 and 9 at step 110, initializes the stored value Ao of the probability counter to “0” at step 111, and displays the symbol at step 112. Output the display signal. The display board 20 displays the start symbol elements P1, P2, and P3 in order from the top in the three display areas 20a to 20c, as shown in FIG. 4A, by driving the drive circuit 20d. However, the start symbol may be any combination of symbol elements, or a completely different completed symbol may be used. Next, in step 113, the probability counter starts counting up the numbers 0 to 939, and counts up by "1" every fixed time. When the count value reaches 939, the probability counter returns to 0 and starts counting up. Next, in step 114, it is determined whether or not the game ball is a first type starting port 13 winning. When the game ball wins the first type starting port 13, the control circuit 61 shifts the program to step 115 based on the determination of “YES”, and simultaneously reads the count value A of the probability counter in step 115. . In step 116, the control circuit 61 stores the count value A as Ao in the RAM. In step 117, a symbol variation start signal is output, and the symbol elements P1 to P15 are continuously scrolled in the horizontal direction and displayed on the display board 20 by driving the drive circuit 20d.
[0020]
  Then, after the game ball has won the first type starting port 13, when t1 seconds elapse, it is determined "YES" in step 118, and the program is shifted to step 119 to determine whether or not Ao is a big hit. . The jackpot number is determined in advance and stored in the ROM, and the probability of jackpot for winning the game ball to the first type starting port 13 is 1/225, for example. If the winning at the first type start port 13 does not correspond to the jackpot, the control circuit 61 shifts the program to step 120 based on the determination of “NO” at step 119 and is stored in the ROM at step 120. A missing symbol selection area which is a combination of symbols indicating a predetermined deviation is selected. In step 121, the control circuit 61 selects a predetermined combination of stop symbols (lower symbol element Pa, middle symbol element Pb, upper symbol element Pc) from the missed symbol selection area. Here, the symbol combination (lower symbol element P3, middle symbol element P2, upper symbol element P1) is selected.
[0021]
  Further, in step 122, the control circuit 61 first determines and displays the lower symbol element P1 after t2 seconds after determining whether or not the big symbol element P1 is a big hit. Next, in step 123, the control circuit 61 displays the variation pattern for t2 seconds in the same manner as the lower symbol element for the middle symbol element P2 in the selected symbol, and finally displays the symbol P2 as the symbol P2. indicate. Next, in step 124, the control circuit 61 displays the variation pattern for the upper symbol element P1 among the selected symbols for t2 seconds, and finally displays P1. Then, the off symbol (P3, P2, P1) is displayed on the display board 20 for a predetermined time and then erased in step 125. In step 133, the stored value Ao based on the probability counter is deleted. Thereafter, the program is returned to step 114, and the processes of steps 114 to 125 and step 133 are repeated.
[0022]
  When the winning of the game ball to the first type starting port 13 is a big hit, the control circuit 61 shifts the program to step 126 based on the determination of “YES” in step 119, and in step 126 the ROM The jackpot symbol selection area, which is a combination of symbol elements indicating the predetermined jackpot stored in, is selected. In step 127, the control circuit 61 selects a predetermined symbol combination (lower symbol element Ps, middle symbol element Ps, upper symbol element Ps) from the jackpot symbol selection area. Here, the symbol combination (lower symbol element P2, middle symbol element P2, upper symbol element P2) is selected.
[0023]
  Further, in step 128, the control circuit 61 first displays the fluctuation pattern for t2 seconds for the lower symbol element P2 among the selected symbols, and finally displays P2. Next, in step 129, the control circuit 61 displays the variation pattern for t2 seconds in the same manner as the lower symbol element for the middle symbol element P2 in the selected symbol, and finally displays P2. To do. Next, in step 130, the control circuit 61 displays the variation pattern for the upper symbol element P2 among the selected symbols for t2 seconds. Here, for the upper symbol element, before displaying the final P2, as shown in FIG. 4 (b), after passing once to the subsequent symbol element P3, it is returned to P2. As a result, the fluctuation of the expectation until the big hit is confirmed is great, and the game is thrilled. Then, in the following step 131, a predetermined jackpot processing routine is performed.
[0024]
  The jackpot processing routine displays the jackpot display symbol PA2 (see Fig. 4 (c)) indicated by the combination of symbol elements (P2 P2 P2), then erases the numbers from the symbol PA2 and causes the girl to wink (not shown) Further, as shown in FIG. 5 (a), the opening of the special winning opening is changed to a special winning opening opening design in which the heart has jumped out from the girl. When the game ball further wins a V in the grand prize opening, the display changes to a V winning symbol with a new V mark as shown in FIG. 5B. Thereafter, the display board 20 repeatedly displays the jackpot display symbol, the big winning opening opening symbol, and the V winning symbol until the big hit state is finished. When the jackpot state ends, the program proceeds to step 132, and the jackpot symbol displayed on the display board 20 is erased. Thereafter, in step 133, the stored value Ao based on the probability counter is deleted. Thereafter, the program is returned to step 114, and the processes of steps 114 to 133 are repeated.
[0025]
  As described above, in the above-described embodiment, the occurrence of so-called jackpot is made to correspond when a symbol completed by a combination of symbol elements displayed in the upper, middle, and lower display areas appears on the display board, and further after jackpot Because the display is rich in changes, the display is very varied and superior in aesthetic effect compared to the conventional jackpot display that simply combines numbers, so the player can use the display board in addition to the game itself.
