What Is a Slot?


A slot is an opening, hole, groove, vent or slit that can be used to accommodate something. In computer technology, a slot is a physical or virtual device on the motherboard that accepts an expansion card. The slots on the motherboard vary in number and location and can be configured to accept different types of cards.

Despite their reputation as arcade devices for old ladies, slot machines have become the gambling industry’s driving force, bringing in most of its profits. According to one casino official, slots account for 85 percent of all gambling revenues.

Casino managers are reluctant to increase the house advantage of their slots too much because they fear killing the golden goose, which is to say, losing enough players to hurt their bottom lines. In addition, many casinos have discovered that even modest house advantages are easily detectable by their customers.

The house advantage of a slot machine is the average percentage of time the machine pays out winning combinations to the player. The term is derived from electromechanical slot machines’ tilt switches, which made or broke a circuit to detect any kind of malfunction (door switch in the wrong position, reel motor failure, paper out, etc.). Modern electronic slot machines do not use tilt switches, but the term “tilt” is still used to describe any technical fault that might cause a machine to misbehave.
