PROBLEM TO BE SOLVED: To suppress players defecting to play a game and improve an availability ratio by achieving a fresh new method as a method for foretelling a result of a jackpot determination for reservation produced during a jackpot game.SOLUTION: A result of a read-ahead determination when a fourth reservation is produced during a jackpot game turns out a jackpot. When the jackpot game is finished, variation/performance patterns, the variation time of which is fixed to a same variation timeΔta are continuously displayed four times. The variation/performance patterns to be displayed in each time comprise stories having mutual relevance. A total variation time required from starting the display of first variation/performance patterns to finishing the display of fourth variation/performance patterns is fixed to ta. The variation timeΔta is calculated by quartering the total variation time ta (Δta=ta/4). |
