In computing, a slot is an opening in the motherboard for an expansion card such as an ISA (Industry Standard Architecture), PCI or AGP slots. It may also refer to a memory slot on the same motherboard.

In a game of slots, the number of symbols on a reel determines the odds that a winning combination will appear. These symbols are usually of varying colors and designs depending on the machine’s theme. Generally, the more matching symbols on a payline, the higher the payout amount.

Charles Fey is credited with introducing the first modern slot machine. Unlike the earlier machines by Sittman and Pitt, Fey’s machine allowed for automatic payouts and had three reels. Its symbol selection was more modern as well; it included diamonds, spades, horseshoes, hearts and three aligned liberty bells. The addition of these symbols made it easier for the average player to win.

Fey also innovated the hopper, which was an additional storage container for coins that could be dropped into the machine to activate the reels. This greatly increased the machine’s revenue potential.

A common myth associated with playing slots is that a machine that has not paid out for a while is “due to hit.” While it is true that many casinos place “hot” machines at the ends of aisles, a machine’s chances of hitting are independent of its neighbors and cannot be predicted. This is because modern machines use random number generators, which assign unique combinations of symbols to each reel location.
