SOLUTION: A presentation display device H2 is rotatable by the operation of a presentation control button 26, and the presentation display device H2 is rotated by a prescribed rotation angle for each operation of the presentation control button 26. After the termination of an effective period of operation of the presentation control button 26, the presentation display device H2 is rotated once, or returned to the initial rotation position without being rotated, according to a pattern determined by an advance notice lottery. With these modes of rotation of the presentation display device H2, the advance notice presentation suggesting the possibility of the result of a symbol variation game being a jackpot is executed.
