PROBLEM TO BE SOLVED: To provide a game board capable of ensuring strength of a rail mounted around an outer edge of a surface of the game board.SOLUTION: One portion (flange part 18a) of a front door frame 18 is utilized as a rail in a game machine (Pachinko machine 10) for shooting game balls toward a game area along a rail, and allowing the game balls to flow down the game area to play a game. By utilizing the one portion (flange part 18a) of the front door frame 18 as a rail, mechanical strength of the rail can be increased, and the number of components of a rail member 1400 for composing the rail can be decreased. A space on a board surface 480a, where the rail is disposed, is reduced, and hence an area, where the game balls can move, can be expanded to an outer edge of the board surface 480a.SELECTED DRAWING: Figure 25 |
