PROBLEM TO BE SOLVED: To provide a game machine capable of improving the strength degradation of a game board itself and retaining the rolling motion space of a game ball on the game board.SOLUTION: A variable display device unit of a game board 30 comprises: a mounting member 400, to which a pattern display device of Fig. 3 is attached, and attached to the back side of the game machine 30; a frame member 430 attached in a shape surrounding the display screen to the front face of the game board 30, separately, wherein a recess 402 of the mounting member 400 has a shape larger in a front view than that of a mounting opening 404 of the game board 30; and a luminescent member 408 at a predetermined portion around the display screen in a front view. The luminescent member 408 is so arranged in the recess 402 that the portion other than a luminescent portion 406 may be positioned in a region between the outer circumference of the recess 402 and the mounting opening 404 of the game board 30, so that the mounting opening 404 of the frame member 430 and the game board 30 can be reduced to improve the strength degradation of the game board 30 itself thereby to retain the rolling motion space of the game board 30. |
