PROBLEM TO BE SOLVED: To provide a technique capable of preventing a jackpot game from getting boring.SOLUTION: When a game falls under a specific jackpot (a substantial 4R-substantial 10R) in a normal mode, [F70] a launching challenge bonus is executed. In a specific round of the launching challenge bonus, a point storage performance is executed. When a player can store points to a prescribed maximum value in the point storage performance, it is settled to transfer to [F90] a firework mode (a high-probability and time-shortened state). Further, during the specific round of the launching challenge bonus, a continuation affirmative/negative performance on whether or not a substantial round is continued is executed. As the substantial round increases, a ratio of rushing into the firework mode increases (25%→50%→67%→100%), so that how much profit can be obtained in the jackpot game is directly related to a transfer to the firework mode, thereby preventing the jackpot game from getting boring. |
