PROBLEM TO BE SOLVED: To realize a highly attractive development of games instead of such solutions as attempts to simply facilitate the hitting of big wins while suppressing impatiences of players when minor wins continue. SOLUTION: In the slot machine which is provided with a lottery means for determining the permission of big wins or minor wins at a fixed probability and performs output operations when the permission of wins is determined thereby while figures corresponding to the permission of wins determined are stopped on winning lines L1 to L5 of whole pattern display parts 2a to 2c, when a low putting out by minor wins continues up to a certain frequency, the probability of determining the permission of wins at the subsequent lottery by the lottery means is raised by a control means. Games can be developed in higher varieties by setting the probability of determining the permission of minor wins or big wins to proper values. The frequency of the continuation of the low putting out processing is made known by lighting display lamps 9a to 9c thereby allowing players to harbor expectations.
