<P>PROBLEM TO BE SOLVED: To provide a game machine increasing player's interest in game play even when a game exists in a presentation mode having a low expectation of winning probability oscillation. <P>SOLUTION: A general control CPU controls the shift of a presentation mode showing the expectation of winning probability oscillation which indicates awarding of winning probability oscillation as a current game state. The general control CPU controls the shift of the presentation mode to another presentation mode at a high probability relative to the determination of a variation pattern having a low degree of expectation of a jackpot, when a variation pattern having a high degree of expectation of a jackpot is determined while the presentation mode having a low degree of expectation of the winning probability oscillation exists. <P>COPYRIGHT: (C)2012,JPO&INPIT |
