<p><P>PROBLEM TO BE SOLVED: To make a player more interested in the announcement presentation for generation of a special game state, and to enhance the eagerness of the player for the participation in the announcement presentation for generation of the special game state. <P>SOLUTION: A presentation controlling microcomputer 100 sets a presentation period (the number of times of presentation) for executing a probability-variable upgrade presentation when execution of the probability-variable upgrade presentation is specified in a jackpot game round based on a received symbol/presentation specifying command. In this case, when a probability-variable jackpot is predetermined, the microcomputer sets a longer period (a larger number of times of presentation) as the presentation period for the probability-variable upgrade presentation than when a normal jackpot is predetermined. Then, the probability-variable upgrade presentation is executed according to the set presentation period, and when it is determined that a prescribed condition for the upgrade is satisfied by detecting an on-signal from a control button 120, the upgrade to the probability-variable game state is announced. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
