PROBLEM TO BE SOLVED: To improve a producing effect by giving modulation to the display of symbols. SOLUTION: In each reel 8a, 8b and 8c, the part of a symbol is formed of a translucent layer and a light shielding layer is provided at a background part. Further, on the rear side of the reel 8a, 8b and 8, a planar light source incorporating LEDs of three primary colors coordinated with the stopping and displaying position of the symbol. On the other hand, as a BB prize winning, three-kinds of prize winning having different prize-winning contents are set coordinated with the combination of the symbols of '7' by each color of red 7, blue 7 and white 7. When forming the BB prize winning by the symbol of red 7 or blue 7, by retracting control of the reels 8a, 8b and 8c, the combination of the symbols of white is formed first and the light emitting color of a light source corresponding to each symbol is changed to a color corresponding to desired BB prize winning.
