PROBLEM TO BE SOLVED: To keep a player's interest by avoiding such change of a presentation mode as to disappoint the player. SOLUTION: One presentation mode is selected from among a concealed (high) probability variable mode, a concealed (intermediate) probability variable mode and a concealed (low) probability variable mode with different degrees of expectancy for the control in the probability variable state according to whether the play is actually controlled in the probability variable state after termination of a second jackpot game state based on a sudden probability variable jackpot or minor winning. The respective rates of selection of the concealed (high) probability variable mode, concealed (intermediate) probability variable mode and concealed (low) probability variable mode when stored memories include those leading to the sudden probability variable jackpot or minor winning are different from the rates of selection when the stored memories do not include those leading either to the sudden probability variable jackpot or to the minor winning.
