Provided is a game machine capable of providing guidance so that, at an appropriate timing, the player performs the action of changing from a contacting state in which he/she is contacting a predetermined region to a non-contacting state in which such contact is not performed. The game machine provides a dance game for providing guidance about the performance timing of a dance step, and evaluating the actual step performance timing. The game machine comprises a stage sensor that detects a contacting state in which a foot of a player is contacting a treading surface of the stage, and detects a non-contacting state where such contact is not performed. The game machine also provides guidance about the time of a foot-lifting action as the step performance timing, and evaluates the time as the actual step performance timing, so that a foot-lifting action changing functions as the dance step.
