PROBLEM TO BE SOLVED: To provide a game board made of resin, which can be stably stacked up, without having a risk of damage on the surface at stacking and is easy to store and transfer by overlapping the boards in a tongue-and-groove manner.SOLUTION: The game board made of resin, which is integrally formed by injection molding, includes: openings 2a-2c in various forms, attaching game board of a variable winning pocket, an electric display or the like; reinforcing edges 3a-3c formed to project on the inner peripheries of the openings for reinforcing the openings, toward the back; thick parts 4a-4g for driving nails such as game nails or wind wheels being driven into; and a reinforcing rib 8 on the outer periphery of the board, projecting to the back. A step-like recessed cutout 9 cut out in a stepped manner is formed on the outer peripheral part of the surface. Further, when the game boards are stacked, the front end of the reinforcing rib of the upper game board loose-fits in the step-like recessed cutout of the lower game board. Under this loose fitting state, the protruding lengths of the edges and the thick parts to the back are set so that the edges and the thick parts of the upper game board are apart from the surface of the lower game board. |
