<P>PROBLEM TO BE SOLVED: To provide a game machine for removing the monotony of a game while suppressing speculative mind and thereby suppressing a decrease in interest of a player. <P>SOLUTION: The game machine includes a 15R probability variation jackpot for allowing a fixed quantity of prize balls to be won and a 2R jackpot in which it is hard to win a fixed quantity of prize balls. A game state is controlled into a high probability state after the 15R probability variation jackpot is over and is controlled into a high probability state after the 2R probability variation jackpot of 2R jackpot is over. By using the 2R probability variation jackpot as a means for suppressing a decrease in probability by which jackpot is determined to occur and raising rate of continuity of a high probability state, a decrease in probability is prevented even when the rate, by which the game is in a high probability state after a jackpot game state is over, is, for example, substantially raised up to 70 or 80%. <P>COPYRIGHT: (C)2012,JPO&INPIT |
