PROBLEM TO BE SOLVED: To provide a game machine capable of preventing a fraudulent act which can not be easily found. SOLUTION: The game machine 1 detects the variation starting operation to start a unit game, and symbols necessary for the game are variably displayed according to the variation starting operation. Then, random numbers are extracted for each unit game according to the variation starting operation, and an internal winning hand is determined based on the extracted random numbers. Variable display of the symbols is stopped based on the internal winning hand automatically after the elapse of a prescribed period of time or according to the stopping operation by the player, and game media are given to the player based on the displayed stopped symbols. The game machine 1 calculates the timing of the detected variation starting operation, and determines whether the calculated timing of the detected variation starting operation is a prescribed cycle or not. If the timing of the variation starting operation is the prescribed cycle, the player is informed that the timing of the variation starting operation is the prescribed cycle.
