What is a Slot?


A notch or opening, as in a door or window. Also called slot, aperture, slit, or hole. In ornithology, the narrow notch between the tips of the primaries of certain birds that helps to maintain a steady flow of air over the wings during flight.

A time or place allocated for an aircraft to take off or land, as authorized by an airport or air-traffic control. Also called a slot (def 2).

An assigned position in a series, sequence or order, as of jobs or duties: We were assigned to the slot behind the counter. (American Heritage(r) Roget’s Thesaurus)

In the simplest mechanical machines, a payout is detected by a light above or below each reel that lights up when a winning combination of symbols is displayed. Modern slot machines, however, use computers to determine the outcome of each pull. The microprocessor inside a modern slot machine identifies the positions of each reel’s symbols with great precision, and a random number generator produces a new outcome for every spin.

Some modern video slots offer multiple paylines, while others feature stacked symbols and different types of bonus events. Games that have large jackpots are usually considered gambling games, while those with low hit frequency are often entertainment-style titles. The number of reels, type of bonus event and the presence or absence of a free spin bonus are all factors that can help a player decide which game to play. Those who want to maximize their chances of winning should look for games that have a high payout percentage.
