PROBLEM TO BE SOLVED: To prevent the decline of the rigidity of a game board by attaching a center decoration device to the back surface of the game board. SOLUTION: In the game board, a hood component 6 and a stage component 7 are attached to the front surface 1a of the game board 1, and the center decoration device 8 is attached to the back surface 1b of the game board 1 to constitute a center accessory 5. Since the center decoration device 8 to be a part of the center accessory 5 is attached to the back surface 1b of the game board 1, it is not needed to provide the game board 1 with an opening for attaching the center decoration device 8, and the decline of the rigidity of the game board 1 by such an opening is evaded. Even without increasing the plate thickness of the game board 1 or providing a reinforcing rib or the like, the rigidity of the game board 1 for making spike adjustment possible is secured.
