PROBLEM TO BE SOLVED: To allow a player to easily recognize difference in development in increasing variations of the development of continuous advance announcement presentation. SOLUTION: In the continuous advance announcement presentation, the developments of continuous advance announcement presentation are increased by combining a regular variation cycle and a shortened variation cycle defined according to the length of the symbol variation time from the start of variation to the stop of variation of symbols. The player can recognize a change of the symbol variation time by the stop sound presentation even if the player can not notice the change of the symbol variation time or misses the change in the continuous advance announcement presentation. As a result, by changing the kind of the sound in stopping variation of symbols, the difference in development can be appropriately recognized by the player, and therefore, the difference in development can be easily recognized by the player in increasing variations of the development of the continuous advance announcement presentation.
