A slot is a small opening, especially in an instrument or door. The term is also used in computer engineering to describe an expansion slot on a motherboard, for example ISA (Industry Standard Architecture), PCI or AGP slots. The word is often used in sports to describe a position or spot in front of the goal, such as the unmarked area on an ice hockey rink between face-off circles.
The modern slot machine produces the bulk of profits in most casinos, and it is gaming managers’ job to keep their players seated, betting and playing. To do this, they must offer a combination of factors that make their machines fun, exciting, and psychologically addictive:
Charles Fey’s 1899 “Liberty Bell” machine, now a California Historical Landmark, was the first of many such devices. His invention, with its beeps, bells, and spinning cherries and lucky sevens on liquid crystal displays, quickly became a mainstay in saloons.
Eventually, microprocessor technology allowed casinos to lower volatility, make games more exciting, and add mini-games and other bonuses. But the most crucial advance was the introduction of a computer that made it possible to track odds and payouts precisely.
