A slot is a narrow notch, groove or opening, such as a keyway in a machine, a slit for a coin in a vending machine, or a position on a game board. It is also the name of a device for a computer or other electronic equipment. The term may refer to a specific site on a printed circuit board, or to an entire area of the board. A slot is not to be confused with a bay, which is a site for installing disk drives.

Slot is a very common position on the football field, and it has become more important in recent years as teams shift to more spread formations. The Slot receiver lines up slightly in the backfield, a few steps off the line of scrimmage, and is often smaller and quicker than traditional wide receivers. He is expected to master every passing route and to excel in running precise routes. Because of their pre-snap alignment, the Slot receiver is usually a target for opposing defenses on passing plays. In addition, they are a very important part of the run game and help block for running backs. In some instances, the Slot receiver can even be the main ball carrier in certain run plays. They are especially useful on teams that utilize a lot of three-receiver/back formations. A good Slot receiver will have very fast feet and excellent hands. He is able to get open on a variety of pass patterns and make acrobatic catches.
