PROBLEM TO BE SOLVED: To provide a slot machine which enables the diversification of the development in the progress of the games while allowing the further increase of the game media obtainable by the players along with the higher possibility of enhancing the expectations felt for the games by expanding the opportunities of permitting the shift to the special game to other occations not confined to the role lottery. SOLUTION: Two types of special games, first and second, are arranged. The lottery processing to determine whether the shift should be permitted from the normal game to the first special game is carried out up to the operation of the stop switch from the operation of the start switch. The lottery processing to determine whether the shift should be permitted from the normal game to the second special game is conducted before the start switch is operated to start the current game after the lottery processing of the game is done at least once preceding it. At the same time, the lottery probability in the second permission lottery processing is altered from the history information indicating the history of the games. COPYRIGHT: (C)2006,JPO&NCIPI
