A narrow notch or opening, such as a keyway in machinery or a slot for coins in a machine.
The term slot can also refer to:
A position in a queue or list; an allocated time for an aircraft’s departure or arrival at an airport’s runway.
The part of a machine’s reels that holds a coin or paper ticket with a barcode.
In a slot machine, players insert cash or, in “ticket-in, ticket-out” machines, a paper ticket with a barcode into the slot, which activates the reels to spin and then stop to randomly arrange symbols. A winning combination of symbols awards credits based on the paytable. The paytable may also specify a maximum bet, the number of paylines available, and the requirements for triggering bonus rounds or jackpots. The symbols used in a slot game vary and are aligned with its theme. Modern slots often use digital displays and touch-screen technology.
