A position within a group, series, or sequence. A slot can also refer to:

The slot in the wing or tail surface of an airplane, used in connection with a high-lift or control device; a notch or groove in the surface of a door or window, into which a bolt may be inserted.

An area in the wing or tail surface of an aircraft, used in connection with a high-lift and control device; an air gap between the wing and the auxiliary airfoil, allowing for a smooth flow of air on the upper surface. A notch or groove in the surface of s doors or windows, into which a bolt may be slipped to lock it.

Slang, sometimes in reference to a passenger seat or berth, where a person is “slotted in”. Also:

In casinos, where the minimum bet on a penny machine can be less than one dollar, the machines are often clustered together in their own section of the floor. In this way, the player can get a taste of the higher limits without leaving their comfort zone.

It’s important to remember that all payouts at slots are based on random chance. Don’t be fooled by people who say a particular slot is ‘due’ to pay out. The result of every spin is independent from previous results, as each combination is randomly sorted and chosen by the slot software. Even though you’re playing for fun, you should still make sure the games you choose are appropriate for your risk tolerance level.
