A slot is a narrow notch, groove, or opening, as in a keyway in a piece of machinery or a slit for a coin in a vending machine. It can also refer to a specific position in a group, series, or sequence, as in the slot in a hockey rink between the face-off circles, or to a time period reserved for a particular activity, as in “the slot is open”.

A slot machine is a casino game that uses a reel to display symbols and pay out credits based on a pay table. A player inserts cash or, in “ticket-in, ticket-out” machines, a paper ticket with a barcode, into a designated slot and activates it by pushing a button (either physical or on a touchscreen). In electronic slot games, the number of symbols that appear on each reel is predetermined, and they may be weighted so that lower paying symbols occur more frequently than higher paying ones. In addition, many slot machines have a jackpot amount that must be won in order to qualify for the highest payout. This payout structure is often referred to as a percentage return to player, or RTP.
