A slot is a narrow opening or groove. It can also refer to a position or period of time. A slot can be used for a game of chance, or to play video games. It is a common part of computer hardware.

In computing, a slot is a unit of execution for an operation in a very long instruction word (VLIW) machine. The term is also used to describe the portion of a computer’s processor devoted to the execution of a VLIW program, or the pipeline that executes it. In a VLIW system, a slot is more precisely a functional unit, but the concept is the same.

When a player inserts cash, or in the case of “ticket-in, ticket-out” machines, a paper ticket with a barcode, into a slot machine, a random number generator determines which symbols will appear on the reels. When a winning combination of symbols is displayed, the player earns credits according to a pay table. Pay tables vary by machine, but many slot games share a theme. Classic symbols include fruit, bells, and stylized lucky sevens.

The’slot’ in the name is intended to convey the sense of a fixed, limited space. In football, the slot receiver is a deep receiving threat who can run vertically and disrupt routes at the line of scrimmage. The most popular slot receivers in the NFL are usually tall, fast players who can outrun safeties and catch passes thrown high.
