PROBLEM TO BE SOLVED: To increase excitement and enjoyment of a game by keeping up players' expectation of a probability variation condition even after an opening time-increasing condition comes to an end by relating a performance announcing to the players that they can have an expectation of the probability variation condition to a performance after the opening time increase condition comes to an end. SOLUTION: When a ball entrance rate-increasing condition is granted, after a first 2R probability variation jackpot game or a 2R nonprobability variation jackpot game comes to an end, the game machine announces to the players that they can have an expectation about a probability variation condition by a CH mode. Furthermore, when the ball entrance rate-increasing condition comes to an end by the elapse of a maximum granted period of the granted ball entrance rate-increasing condition after shifting to the CH mode, after the first and third 2R probability variation jackpot game or a 2R nonprobability variation jackpot game comes to an end, the game machine can keep up the players' expectation by making a preparation mode giving an opportunity to shift to an SU mode and an MS mode permitting a shift thereto when the winning rate-increasing condition is not granted, to be executed even after the ball entrance rate-increasing condition comes to an end.
