Abstract: To provide a game machine capable of improving an amusement of games.SOLUTION: Multiple pieces of start information can be stored. Determination by specific presentation determination means has different probabilities for firmly determining to perform a specific presentation depending on a number of pieces of start information stored when the determination is performed. The specific presentation is, if it is firmly determined by determination means that a special game is to occur during a prescribed period, to suggest a possibility that a specific game is to be started after the special game is finished. If the specific presentation determination means determines to perform the specific presentation on the basis of the start information stored during a variable display of identification information, the specific presentation is not to be started during the variable display of the identification information, but the specific presentation is to be started after the variable display of the identification information is finished. During a prescribed period, when the determination means performs a determination with respect to the start information, and consequently if it is determined that the special game is to occur and the specific game is not to occur, a control is performed to finish the specific presentation before the special game is to be started.SELECTED DRAWING: Figure 285
