A slot is a part of an execution unit (or FU) that issues and executes instructions. It also contains the data path machinery that manages the flow of commands and data to and from the FU.

In a video game, a slot is a specific position on the screen that can be filled by a particular symbol or action to trigger a bonus round or other special event. For example, a player might land on a “sequential wilds” slot, which causes a chain reaction that can yield free spins or jackpot payouts.

Traditionally, a slot machine accepts cash or paper tickets with barcodes (in “ticket-in, ticket-out” machines), which are inserted into a slot to activate the reels. The machine then displays a series of symbols on its face and pays out credits according to the pay table. Some slots have a progressive jackpot, while others offer fixed rewards. Many slots have a theme, and the symbols and bonus features often align with that theme.

The term “slot” is also used to refer to a specific time period when a television or radio program is broadcast. The word is often shortened to simply “slot” in everyday speech, and this use has caused some confusion. Despite this, the term is still widely used in the gaming industry. A slot in a video game can be filled by any symbol or action, but most commonly, it is the time when players can expect to receive a prize.
