A slot is a narrow aperture or groove that can be cut, machined or formed. Examples include the slots in a window, door, or wall and the slit in a piece of wood or metal. A slot may also refer to an area of an aircraft or vehicle in which passengers or cargo can be seated or loaded.

The word slot is often used in business to describe a specific period of time when a task should be completed. The use of this scheduling method is prevalent across many industries, and it can help organizations organize their workflow and support project objectives. Health care providers, for example, often rely on time-based slots to schedule appointments with patients and clients.

On a video slot machine, the pay table is shown in a display window above and below the reels. The pay table lists the number of credits that a player will receive when the symbols listed on the pay line appear in a winning combination. The symbols that are eligible for a payout vary by game, but typically include fruits, bells, and sevens. Some machines also feature a wild symbol, which substitutes for other symbols to complete a winning combination.

The term jackpot enjoys a brief, unofficial tryout as slang for the highest prize in a poker game (ante that accumulates until someone wins with a pair of jacks or better). It is also the name of the top prize in some gambling games, including slot machines and horse racing.
