A slot is a time-slot that an airline is allowed to operate at a specific airport. Slots are important because they enable airports to manage air traffic in a way that prevents repeated delays. Airlines can buy and sell slots for a wide variety of reasons. In 2016 alone, one slot sold for $75 million.

While old-fashioned mechanical slot machines were limited in number, modern ones are more flexible and easier to program. In addition, they don’t have to be as large as their mechanical counterparts. For instance, in the old days, a single reel could only have one symbol, while a modern computer-programmed slot can have twenty symbols on each.

The slot is a great place for a defenseman to take a shot. Some defenders have the skills to take a blistering slap shot into the net, while a winger or center can put his stick out in front of the goalie to redirect a shot. As a result, goalies are often forced to react lightning-fast to a puck. A well-placed one-timer from the high slot is one of the best shots in hockey.

Another position whose importance is rising is the slot receiver. As more teams utilize a spread offense, the slot receiver plays a crucial role. This position can be combined with other receiving positions. A slot receiver lines up between the offensive tackle and the widest wide receiver and is often fast and agile. As such, they are prime candidates for receiving the ball. A slot cornerback is usually a smaller defensive back that specializes in covering slot receivers.
