PROBLEM TO BE SOLVED: To provide a stage structure of a center prize-winning role object for a game machine with which a player is interested in a game and enjoys it without taking his/her eyes off rolling of game ball since there are so various patterns in rolling of the game balls. SOLUTION: As for a stage surface 34, a cross section in a short length is curved in a recess state and has a shape of a surface connected in the state of a half pipe surface in a right and left direction. The stage surface 34 is formed to be gradually lowered from a stage surface 34a on its left end side and a stage surface 34b on its right end side toward a stage surface 34c in its center in the right and left direction. In a nearly semi-circular area on this side of a specific entrance 44, a nearly plane guiding surface 50 with a down slope toward the entrance 44 is formed. A position 50a on the front-most side of this guiding surface 50 is provided so as to be at the same level without giving a level difference with the lowest position of the stage surface 34c in the center in the right and left direction.
