In football, the position responsible for lining up in the middle of the defense between the outside wide receiver and the running back. First conceived by Sid Gillman while coaching the Oakland Raiders, the slot receiver was designed to attack three levels of the defense — the line of scrimmage, linebackers, and secondary. The position has since become a staple of any quality team.

A screen that displays the player’s current credit total on a mechanical or video slot machine. On older machines, this was a simple seven-segment display; on newer video games, it is a high-definition LCD that is customized to suit the game’s theme. It also flashes to alert the operator that change is needed, hand pay is requested, or a problem with the machine has occurred.
