PROBLEM TO BE SOLVED: To provide sufficient amusement by utilizing the game area of a game board as a performance area.SOLUTION: A cell part is arranged behind a game area so as to face this game area. The cell part comprises a lamination conductor 7701 in which conductive plates made of light-transmissive synthetic resin are arranged in layers in forward and backward directions, the front of each conductive plate serving as a light guide emission face. Background patterns 7720a to 7720c that appear by scattering of light are recorded on the corresponding light guide plates. The background patterns show a common character 7720 and is designed such that the shape of each recorded pattern gradually increases toward the light guide plate located furthest front from the rearmost light guide plate. A periphery control section sequentially turns on light sources from the light source corresponding to the rearmost light guide plate 7704 to the light source corresponding to the light guide plate 7702 located furthest front. The background patterns on the corresponding light guide plates are sequentially shown, thereby displaying the background pattern of the game area stereoscopically. |
