What is a Slot?


A thin opening or groove in something, such as a door, window, or other object. Also called slot or slit.

A slot is a mechanism in which a coin is deposited into a gambling machine to activate the game and payout credits according to its paytable. Modern slot machines, also known as video games or fruit machines, use a random-number generator (RNG) to determine the results of each spin. The random-number generator generates a sequence of numbers, each representing a different possible symbol combination on the reels. When a spin is completed, the RNG checks each symbol to see if it matches one of the winning combinations in the paytable. The machine will then stop spinning, and if all symbols match the winning combination, the player receives the payout.

Slots can be played with cash or, in “ticket-in, ticket-out” machines, paper tickets containing barcodes. The machine may be activated by pressing a physical lever or button, or, on newer machines, by scanning a ticket or barcode with a special scanner. In addition to a paytable, most slot machines feature a theme, such as a specific location or character, with symbols aligned with that theme.

Some players believe that a slot machine is due to pay out if it has gone long without paying. This belief is based on the fact that a machine’s result after a long losing streak would be the same as its result after a short winning streak. This is not true, though. Each spin is independent, and a machine’s previous results have no bearing on its future results.
