In a casino, the area where a slot machine pays out winnings. The slots in a slot machine are usually marked with symbols of varying values.

The reels in a slot machine wiggle to make the game more visually interesting, but there is no way to know whether a particular waggle is indicative of a future win. Some players believe that if a machine has not paid out for a long time it is due to hit soon, but this is untrue, as every spin of a slot is independent and random.
