What is a Slot?



A narrow opening in something that can fit something into. The car seat belt slotted into place easily. A time slot in a schedule or program. He was on a waitlist for a class, but the instructor got a cancellation and offered him a different time slot.

An opening in a wing or tail of an airplane to accommodate an airfoil or control surface. Also called an “air gap”.

In a slot machine, a player inserts cash or, in ticket-in, ticket-out machines, a paper ticket with a barcode, into a slot on the machine and activates it by pressing a lever or button. The reels then spin and, if a winning combination is displayed, the player receives credits according to the paytable. The symbols on a slot machine vary, but classic symbols include fruits, bells, and stylized lucky sevens. Most slot games have a theme, and the symbols and bonus features are aligned with that theme.

Psychological research has typically examined the effects of music in isolation from other sensory modalities, but in slots, sounds are invariably paired with images. It is thought that this synchronization amplifies the effect of sound in generating arousal.

A slot is an open position in a queue or series of events, such as a flight itinerary. A slot-based system allows individuals to book activities such as consultations and evaluation reviews around their availability, while also allowing individuals to reschedule their plans without incurring penalty fees.
