The slot in a game of chance is the place on a machine where the player puts in his or her money, and a display shows how much he or she has won based on the payout table. Some machines also have a “service” or “help” button that flashes to alert the player that a change of currency is needed, a hand pay is requested or a problem has been detected.
In football, the Slot receiver is a wide receiving position that lines up slightly off the line of scrimmage and can be used in a variety of ways. They often act as a decoy on running plays like pitch, reverse and end-arounds, but are also called upon to block (or at least chip) nickelbacks, outside linebackers and safeties. Because of their physical dimensions, they are usually quicker and more agile than traditional wide receivers.
In computer science, a slot is a container that can hold a template fragment within a parent scope and then render it in a child scope. The slot is an alternative to a function call, but with the additional benefit of passing data from the parent scope into the child. The name derives from the fact that a slot is an open container and not a closed function call, unlike a function. It is also an alternative to a lambda call, but with the added benefit of being able to pass variables. For this reason, slots are particularly useful when dealing with dynamic templates.
