<P>PROBLEM TO BE SOLVED: To provide a technique by which a game is prevented from being monotonous by making motion faster and slower in a series of operations performed by a player. <P>SOLUTION: When it is determined that a predetermined starting condition is established, a mission performance is executed to present a special symbol combination to a player when the rotation of a rotary drum is stopped. Further, a privilege is given to the player when the special symbol combination is stop-displayed during execution of the mission performance. Then, when the rotation of the drum is started during presentation of the special symbol combination, the presentation of the special symbol combination is ended. Accordingly, since a player can operate a rotation starting member after sufficiently checking the presented special symbol combination, the operation of the rotation starting member becomes slower compared to a case when the mission performance is not executed. Thus, since the flow of series of operation by a player is made slower or faster depending on presence/no presence of the mission performance, the game is effectively prevented from being monotonous. <P>COPYRIGHT: (C)2012,JPO&INPIT |
