PROBLEM TO BE SOLVED: To provide a game machine capable of reducing the variation on the frequency of the variable display of patterns per hour. SOLUTION: The game machine has a variable display time selection rate shifting means. The variable display time selection rate shifting means sets the probability of selecting short variable display time shorter than the reference variable display time from a plurality of variable display times higher than the probability of selecting long variable display time longer than the reference variable display time if the time of continuous variable display is longer than the reference time of variable display, and sets the probability of selecting long variable display time from the plurality of variable display times higher than the probability of selecting short variable display time if the time of continuous variable display is shorter than the reference time of variable display, as a result of comparison by a variable display continuance time comparison means when the variable display time is selected by a selecting means.
