PROBLEM TO BE SOLVED: To enhance a player's interest and the degree of expectancy for a jackpot by making symbols on an inner drum look as if frames of symbols are advanced in triple-structured drums. SOLUTION: One round of a symbol line is composed of symbols on an outer symbol sheet 42 of an outer drum and symbols on a center symbol sheet 52 of a center drum 50. When prescribed presentation is selected, the rotation of the drums is temporarily stopped with the borderline between the outer symbol sheet 42 and a transparent part 43 of the outer drum 40 located at the center of a display window 10a, and after that, the outer drum 40 and the center drum 50 are controlled to rotate in opposite directions from each other, so that the symbols on the inner drum 60 can be seen only when the transparent part 43 and a transparent part 53 are superimposed on the display window 10a. By stopping the rotation of the inner drum 60 when the symbols can be seen and rotating the inner drum 60 when the symbols can not be seen, such presentation that the symbols on the inner drum 60 look as if symbol frames are advanced is executed.
