PROBLEM TO BE SOLVED: To utilize a game area on a game board as a display area for transmitting a message to a player.SOLUTION: A cell part 7700 includes a laminated light guide 7701 that is disposed while facing a game area at the rear of the game area and allows light guide plates made of a synthetic resin having light transmission properties with the front face as a light guide emission surface to be overlapped in a plurality of layers in a longitudinal direction. At least one of the plurality of light guides is used for recording messages (rear light guide plate 7704) and a message 7760 expressed by scattering of light is recorded. Each remaining light guide plate stores each background pattern expressed by light scattering. A control part lights up a light source of the light guide plate for recording messages according to predetermined message display conditions and allows the message 7760 to appear in the cell part. |
