SOLUTION: This slot machine is equipped with a deformable first passage wall section 118, a deformable second passage wall section 119, and a passage deforming device 150. In this case, the first passage wall section 118 is provided in a disk element introducing passage 110 which is connected with the disk element throw-in section and the blocker device 120, and constitutes at least a part of the side wall which guides the outer peripheral surface of the disk element in the disk element introducing passage 110. The second passage wall section 119 is provided in a manner to face the first passage wall section 118, and constitutes at least a part of the side wall which guides the outer peripheral surface of the disk element in the disk element introducing passage 110. The passage deforming device 150 changes the shape of the disk element introducing passage 110 by deforming the first passage wall section 118 and the second passage wall section 119 when the blocker device 120 performs the switching operation.
