Abstract
Abstract A slot machine having a drive controller for changing the time required for series of symbols to decelerate and stop. For a game that can result in a hit, the series of symbols are controlled to stop by the required stop time set, e.g. longer than that for a game that cannot result in a hit. From the difference between required stop times, a player can know whether the game can be a hit even while the game is still in progress. The monotony of waiting until the series of symbols has fully stopped is thus to some extent relieved.
