To provide a stage structure of a game machine that lengthens the residence time of a game ball by varying the flow of game balls three-dimensionally.
The game balls are oscillated not only two-dimensionally but also vertically by arranging a plurality of climbable protrusions 2 for game balls on a stage 1 of a game machine. The plurality of protrusions 2 can be arranged with intervals in which the game balls can be oscillated and the intervals between the protrusions 2 are preferably less than the diameter of the game balls. Also, the shape of the protrusions 2 is preferably a shape that allows the game balls to contact the protrusions 2 and the stage 1 at a single point and the height of the protrusions 2 is 1-3 mm. Moreover, the stage 1 can be inclined downward from the horizontal line at an angle of 0and 5.
