A slot is a place in a series or sequence. A slot can also refer to a position in an organization or hierarchy. In computing, a slot can refer to an expansion card such as an ISA, PCI or AGP card, or a memory slot on a motherboard. The term “slot” can also be used as a verb, meaning to put something into a slot, or to make a slot for something.

In gambling, a slot machine is a device that accepts paper tickets or coins and pays out credits based on the symbols lined up in a winning combination when the reels stop spinning. Modern slot machines use video screens instead of mechanical reels and are operated by computer chips. They are the primary source of casino revenue and have led to campaigns for increased legalization in many jurisdictions. They are also notorious for their high rates of addiction and dependence. A study by Brown University psychiatrist Robert Breen found that people who play slots develop a debilitating level of addiction three times more quickly than those who gamble on cards or sports.

In ice hockey, the high slot is a prime location for a defenseman to shoot a one-timer into the net. The goalie must react extremely fast to prevent the puck from slipping by. The term can also refer to a spot in front of an opponent’s goal, between the face-off circles.
