To vary the time of one game according to a game state or the like.

The slot machine includes a measurement means for measuring a time period from the time of starting the rotation of a reel 31 in a previous game to the time of operating a start switch 41 in the game, and a waiting means for executing control so as to start the rotation of the reel 31 in the game after reaching the predetermined time T0 when determining that a measured result t by the measurement means does not reach the predetermined time T0 (t<T0). As game states, a non-RT game and an RT game to be more advantageous to a player than the non-RT game are provided. The predetermined time T0 is set at T01 in the non-RT game, and the predetermined time T0 is set at T02 (T02<T01) in the RT game.
