Is not a big hit. Then, the process returns to step S2 and waits for the output of the special figure start signal.

<Determination of a Big Hit (No Symbol Exchange)> A big hit symbol table is recorded in the ROM of the main controller 20. The big hit symbol table shows the relationship between the symbol counter value and the big hit symbol. If the main control device 20 determines that the big hit is made in step S4 of FIG. 4, the process proceeds to step S16, and according to the symbol counter value of step S3. The big hit symbol is selected from the big hit symbol table. As shown in FIG. 1 (i), the big hit symbol refers to a combination of three symbols in which the symbols in the left column to the right column are the same. When the main control device 20 acquires the big hit symbol, The process moves to step S6 in FIG.

When the process proceeds to step 6, the main controller 20 outputs a symbol change command to the display controller 21. Then, the display control device 21 changes the symbols in each column of the special symbol display device 14 in a loop in the setting order of FIG. 2 and displays a symbol change screen.

When the main control device 20 outputs the symbol change command, every time the set time T elapses, step S7 in FIG.
Then, the process goes to S8, and the temporary stop command and the set symbol in the left column (set symbol in step S16), the temporary stop command in the right column and the set symbol in the right column (set symbol in step S16) are sent to the display control device 21. Is output. Then, as shown in FIG. 1A, the display control device 21 temporarily stops the left and right columns of the special symbol display device 14 at the set symbol.

When the main control unit 20 outputs the temporary stop command in the right column, the process shifts to step S9 in FIG.
It is determined that the determination result of 4 is a big hit. Then, the process shifts to step S14 to output a slow change command to the display control device 21. Then, the display control device 21 controls the special symbol display device 1 as shown in FIGS. 1 (b) and 1 (c).
Slowly change the middle row of 4 by about 3 laps.

After outputting the slow fluctuation command, the main control unit 20 proceeds to step S15 in FIG. here,
It is determined that the symbol exchange counter value in step S3 is different from the symbol exchange determination value, and the process proceeds to step S10, where the middle row temporary stop command and the middle row set symbol (the set symbol in step S16) are sent to the display control device 21. ) Is output. Then, as shown in FIG. 1H, the display control device 21 temporarily stops the middle row of the special symbol display device 14 at the set symbol from the slow fluctuation state.

When the main controller 20 detects that the set time T has elapsed since the output of the middle row temporary stop command,

As shown in FIG. 1 (i), the player is notified that the big hit symbol has been determined based on stopping the symbols in each row of the special symbol display device 14.

When the main control device 20 outputs the symbol determination command, the process proceeds to step S12 in FIG. Here, it is determined that the result of the determination in step S4 is a big hit, and the process proceeds to step S17. And the special winning opening solenoid 27
Is performed based on the drive control of the above, and the process returns to step S2.

<Case where Symbol Exchange is Performed at the Time of Judgment of Missing Reach or Big Hit> When the main controller 20 detects that the symbol exchange counter value is the same as the symbol exchange judgment value in step S15 of FIG. 4, the process proceeds to step S18. I do. Here, the temporary stop symbol in the left column (= the temporary stop symbol in the right column) set in step S13 or step S16 is set as the big hit exchange symbol N, and the process proceeds to step S19. For example, when the temporary stop symbol in the left column is “7”, “big hit exchange symbol N = 7” is set.

At step S19, the main controller 20 computes "Na ← (big hit exchange symbol N-1)" and "Nb ← (big hit exchange symbol N-2)" based on the calculation of the off exchange symbol Na. And Nb are set, and the routine goes to Step S20. For example, "big hit exchange symbol N = 7"
In this case, "exchange exchange symbol Na = 7-1 = 6" is set, and "exchange exchange symbol Nb = 7-2 = 5" is set.

When the main controller 20 proceeds to step S20, the main controller 20 outputs a symbol exchange command to the display controller 21, a jackpot exchange symbol N in step S18, and an off-exchange symbol Na and Nb in step S19. Then, the display control device 21 changes the symbol change order in the middle row to the set order based on exchanging the out-of-place exchange symbols Na and Nb in the loop with the jackpot exchange symbol N. For example, when "exchange exchange symbol Na = 6", "exchange exchange symbol Nb = 5", and "big hit exchange symbol N = 7" are set, the middle row of FIG. Symbol change order is "1" →
"2" → "3" → "4" → "7" → "7" → "7" →
It is changed into a loop of “8” → “9” → “0” → “1”...

When the display control device 21 changes the symbol change order of the middle row, as shown in FIG.
Is displayed, a screen is displayed for the effect of irradiating the light on the exchanged symbols Na and Nb. Then, as shown in FIG. 1 (g), the exchange symbols Na and Nb in the first round are exchanged for the jackpot exchange symbol N, and the special symbol display device 1 is used.
In the middle row of 4, a symbol is slowly displayed in a new order by about two turns.

When the main control unit 20 detects that the set time T1 (> T) has elapsed since the output of the symbol exchange command, the process proceeds to step S10 in FIG.
1 outputs a temporary stop command for the middle row and a set symbol for the middle row (the set symbol in step S13 or S16). Then
The display control device 21 temporarily stops the middle row of the special symbol display device 14 at the set symbol as shown in (d) or (h) of FIG.

When the main control unit 20 detects that the set time T has elapsed since the output of the middle row temporary stop command,
The process proceeds to step S11 in FIG. 4 and outputs a symbol determination command to the display control device 21. Then, the display control device 21
As shown in FIG. 1 (e) or (i), the player is informed that the out-of-reach reach symbol or the big hit symbol has been determined based on stopping the symbols in each row.

According to the above-described embodiment, when the symbols in the symbol display area ZE in the middle row are changed on the reach screen, a larger number of big hits than before the reach (here, the same symbols as the left and right rows are used as the big hits) ). Therefore, the degree of expectation of the jackpot on the display and the visual interest are increased, and the fun of the game is improved.

In changing the symbol in the symbol display area ZE in the middle row on the reach screen, a missing symbol (here, a symbol different from the left and right rows is referred to as a missing symbol) is replaced with a big hit symbol. The number of big hit symbols was increased without changing the total number of symbols during one round. Therefore, the total number of symbols in the middle row during one round becomes the same before and after the reach, so that the player does not feel frustrated waiting for the symbols to stop at the time of the reach. In addition, since the relative number increases in addition to the absolute number of the big hit symbols, the degree of expectation of the big hit on the display is further increased, and the fun of the game is generally further improved.

In order to change the symbols in the symbol display area ZE in the middle row on the reach screen, the order of the changes is fixed over a plurality of cycles. For this reason, since the position of the next big hit symbol can be easily grasped, the position of the next big hit symbol cannot be grasped, so that it is not confused or frustrated, and the fun of the game is further improved.

In changing the symbol in the middle row symbol display area ZE on the reach screen, the out-of-off symbol adjacent to the big hit symbol is exchanged for the big hit symbol, so that the big hit symbol is displayed in the middle row symbol display area ZE. The change is continuously displayed, so that even if the big hit symbol passes, it is possible to immediately expect that the next big hit symbol stops changing, so that the fun of the game is further improved. Further, in changing the symbols in the symbol display area ZE in the middle row on the reach screen, the speed of change was made slower than before the reach. For this reason, the increase of the big hit symbols becomes visually clear, so that the fun of the game is further improved.

In the above embodiment, the one-off design and the two-off design before the big hit were replaced with big hits, but the present invention is not limited to this. May be. The counter value is detected at the detection timing of the special figure start signal, and the off symbol corresponding to the counter value is exchanged for the big hit symbol. In this case, the symbol is randomly selected from the symbol variation group, and the big hit symbol appears at an unexpected position, so that the fun of the game is further improved.

The two-off symbol and the three-off symbol not adjacent to the big hit symbol are exchanged for the big hit symbol. In this case, since the big hit symbol is deviated and displayed across the design, the duration of the big hit expectation is lengthened, and the fun of the game is further improved. All the missing symbols in the symbol variation group are exchanged for big hit symbols, and big hits are generated with 100% reliability.
