PROBLEM TO BE SOLVED: To provide a game machine with a function of detecting the rotation position of each rotary reel without giving information as a basis of positions of patterns during the rotation to a player. SOLUTION: The game machine comprises a plurality of reels arranged to rotate independently, a plurality of detected parts formed along the whole circumference on the outer periphery of each reel, and a sensor disposed to face the detected parts. At least one pair of detected parts among the plurality of detected parts are disposed in such a way that the length of the arc between the pair of detected parts on the outer periphery of the rotary reel is different from the length of the arc between the other detected parts.
