PROBLEM TO BE SOLVED: To provide a pinball game machine capable of effectively preventing fraudulent actions such as a cheating action. SOLUTION: The pinball game machine includes: winning invalidating means 407c for validating or invalidating detection information from a winning ball detection means which detects a game ball that enters a variable winning device 320; and specified winning invalidating means 407d for validating or invalidating detection information from specified winning ball detection means which detects a game ball that enters a specified winning area. The winning invalidating means 407c validates the detection information from the winning ball detection means when a series of operations of a blade member based on the generation of an auxiliary game state are started and invalidates the detection information from the winning ball detection means when a first prescribed time elapses after the end of the series of operations of the blade member. The specified winning invalidating means 407d performs control so as to make it possible to generate a special game state until second prescribed time elapses after the detection of the game ball in the case that the game ball is detected by the winning ball detection means while the detection information from the winning ball detection means is validated by the winning invalidating means.
