A slot is a narrow opening, especially one for receiving something like a coin or a letter. A slot is also the term for a position within a sequence or series of events. For example, a company using a slot-based method of scheduling appointments with clients may have different time slots for urgent care, routine check-ups and consultations with new patients.

In online casinos, slots are a virtual game where bettors can wager money by placing advance deposits into the game’s credit meter or bill validator. Until recently, players dropped coins into slots to activate games for each spin but this changed in live casinos when bill validators and credit meters were added to allow people to play without actively dropping in cash. Online slots also use credit meters, and they are often more transparent about the amount of money a player is spending or winning.

The term “slot” is also used in sports to describe the area directly in front of the goal between the face-off circles on an ice hockey rink. Centers and wingers have the best opportunity for a wrist shot in this area because it provides them with a straight-on view of the net.

A slot can also refer to a specific position on an airplane’s wing or tail. An air gap between the wing and a control device, such as an aileron or flap, allows for smooth flow of air on the surface of the wing.
