Abstract
A slot machine repeatedly detects symbols displayed in the middle columns of display windows even after the respective rotatable reels are stopped, and judges whether or not the symbols displayed in the display windows are changed after all the rotatable reels are stopped.
Claims12
A slot machine comprising:
- a rotatable reel including a plurality of symbols drawn on a peripheral surface thereof and being rotatable and stoppable;
- a display adapted to display part of the symbols;
- a sensor configured to repeatedly detect the symbols displayed on the display at least after a stop of the rotatable reel;
- and
- a controller configured to
- (a) execute a unit game for rotating and stopping the rotatable reel,
- (b) determine an outcome of the unit game according to one of the symbols detected by the sensor at a time point of the stop of the rotatable reel, and
- (c) judge whether or not the one of the symbols displayed on the display is changed after the stop of the rotatable reel, according to the symbols repeatedly detected by the sensor after the stop of the rotatable reel.
