PROBLEM TO BE SOLVED: To average a ratio of prize-winning on respective prize-winning lines when prize-winning on two or more kinds of prize-winning lines is possible. SOLUTION: Bit data tables for controlling slippage which supports stopping of a center reel 350B and a right reel 350C on the respective prize-winning lines when an internally winning role is a multiple prize-winning line when a left reel 350A is stopped are prepared respectively separately. Depending on whether a game history (the number of residual credits C in this mode) is even or odd, a bit data table A (even) or a bit data table B (odd) is selected. Thus, selection by probability of reliably 1/2 in a short spun is possible, and biasing of the prize-winning lines in a period in which one player plays a game is avoided.
