To provide a game machine which is structured so as to further complicate the rolling action of game balls over a stage and widely, and to interestingly vary the movements of one game ball.

The Pachinko machine permits ball games to be guided, from the other side to the front side of a stage S and rolled forward and backward and drops down to a drop hole 34a and guided to a first start chucker, after guiding game balls introduced onto the stage S from warped inlet openings 37a and 37b to the back side of the stage S by a first rolling route 34, just at a point when the rolling force becomes comparatively weak. Consequently, the game machine can vary widely and interestingly the movements of one game ball, by rollingly moving the game ball once introduced to the stage S and making the rolling action complex.
