A slot is a narrow notch or opening, as in a keyway in machinery or a slit for a coin in a vending machine. It may also refer to a position in a group, series, or sequence.

Online slot machines offer a variety of bonus features to keep players engaged and potentially spending more money. They can offer jackpots, scatter symbols, wild symbols, or multiple bonus rounds. They are easy to learn and can be played for fun or real money. Online slots are also convenient because they allow players to use electronic payment methods instead of carrying large amounts of cash.

Aircraft pilots use the term “slot” to describe a time period during which an aircraft can take off or land at a particular airport. The term is distinct from “air traffic control clearance” or similar authorizations and does not imply that the flight will actually take off or land during this time. It is a central component of the use of flow management at busy airports in order to prevent repeated delays caused by too many planes trying to take off or land at the same time.

In football, a slot is the position on defense assigned to cover the wide receiver. This position requires speed and athletic ability as the receiver is constantly moving to get open. To counter this, teams often deploy a slot corner or nickel back to help cover the receiver. This forces the offense to run more designed plays and rely on scheme rather than skillful play.
