PROBLEM TO BE SOLVED: To further enhance the amusement of a game when a player plays the game.SOLUTION: When the prior determination of a preservation ball 10E shows a jackpot (refer to (a-1)), a lighting number increase performance is started by a succeeding variation. That is, a drum lamp 11 is lit at a symbol variation of a preservation ball 10B (refer to (b2)), and a drum lamp 12 is further lit at a symbol variation of a preservation ball 10C (refer to (c-2)). When second start port winning occurs before the finish of the symbol variation of the preservation ball 10C, a jackpot lottery of the preservation ball 10C is not performed, the second start port winning is preferentially consumed (refer to (d-1)), and the lighting number increase performance is interrupted with the symbol variation based on the second port winning as a trigger (refer to (d-2) and (e-2)). Then, at the variation of the preservation ball 10E (refer to (f-1)), the lighting number increase performance is resumed, and a performance form of a final stage is executed (refer to (f-2)). This performance is executed even if the prior determination does not show the jackpot.SELECTED DRAWING: Figure 37 |
