The slot is a position in a group, series, or sequence. It is also a position for an airline to operate at certain times in restricted airspace (such as at Heathrow). Air Traffic Management slots, which allow airlines to take up space on the ground or in the sky, are sometimes considered as valuable as land.
The Slot receiver is a position that lines up slightly behind the line of scrimmage and allows him to do a lot of different things with the ball in his hands. He can be a deep threat running precise routes, a typical pass catcher on passing plays, and even a great blocker on running plays.
A Slot receiver will often run his route in a pre-snap motion before the quarterback snaps the ball, giving him the chance to get clear of the defender assigned to him. He is usually faster and more agile than outside wide receivers, but because of his alignment he needs to be especially good at blocking.
The credit meter is a display on the top of a slot machine that shows the player how much money or credits they have won. It can be a simple seven-segment display or it can be a more stylized version that suits the game’s theme. The Slot machine can also have a candle that flashes to alert the operator when change is needed, hand pay is requested, or a technical fault has occurred, such as an out-of-paper error.
