To provide a game machine that can prevent a disadvantage of causing a state that a movable presentation is scarcely executed during playing by a player without greatly enhancing a design value itself of an execution probability of the movable presentation determined at random.
Not only a movable presentation by a random lot control for every variable display that whether or not the movable presentation is carried out is determined by lot at a probability of 1/50 at random for every variation in a special symbol display device, but also the movable presentation by a periodical execution control that the movable presentation is carried out periodically (every 80 times of variation) is carried out in such a manner that the movable presentation is carried out once to 80 times by the movable presentation by the periodical execution control even if the frequency of the movable presentation by the random lot control for every variable display is biased, and the movable presentation is not carried out for a comparatively long period of time.
