A slot is a thin opening or groove in something. For example, you can put letters and postcards through a mail slot on a door or in the wall. A slot can also refer to a position in a schedule or program; you might book your flight at a certain time in a slot on the airline website.
In football, a slot receiver is a wide receiver who lines up in the middle of the field between and slightly behind the outside wide receivers. They are usually responsible for blocking nickelbacks, safeties, and outside linebackers on running plays. It takes advanced skills to block in the slot, and teams tend to emphasize speed and agility for these players.

These findings support the conclusion that casinos use slot machines to generate large amounts of revenue and make gamblers more likely to spend more than they planned.
