The term slot may refer to:
A position or location within a series, sequence or group. In computers, it may refer to a socket (for expansion cards such as an ISA or PCI slot), or a memory slot. It may also be used to describe a portion of the wing of an aircraft that connects it with its control surfaces, allowing air to flow over the upper surface.
In a slot machine, the pay table is listed on the machine, usually above and below the reels or on the side of the machine. The pay tables show what symbols have to be connected in order to win the maximum payout. In addition to the pay tables, some machines have wild symbols that can substitute for other symbols to complete a winning line.
The number of combinations possible in a slot machine is limited by the number of physical stops on each reel. In the past, this was a major disadvantage of slots, compared to other casino games such as poker and roulette. However, when manufacturers incorporated electronics into their products, they were able to weigh particular symbols differently. This allowed them to create symbols with the same probability of appearing on a payline, even though they might appear more frequently on one physical reel than another.
In football, a slot corner is a defensive back who is tasked with covering the slot receiver. This is a difficult position to play because the slot receiver catches many balls all over the field, and the slot corner must be well conditioned and able to read the ball quickly.
