What is a Slot?


Slot is a game in which players attempt to line up symbols on paylines to win prizes. The payouts are determined by a random number generator (RNG), which cycles thousands of numbers every second.

Unlike reel machines, video slots use a number of paylines, which can be a single, multiple or all-ways. When a player lines up symbols on a winning payline, they are awarded credits based on their bet amount.

Bonus Events

In slot machines, bonus events such as free spins and wheel spins can increase a player’s winnings. They also give the player a chance to collect bonus multipliers which can be as high as a third of the overall return.

The Paytable

A slot machine’s paytable is a list of all the symbols on the pay lines and how much they pay. The pay table is usually printed on the front of the machine, above or below the wheels.


A variance is the frequency that a slot pays out, which can vary greatly from one machine to another. Low variance slots pay out smaller amounts frequently, while high variance slots can pay out huge sums of money almost every time a player lines up a combination on a winning payline.


A tilt is a technical fault that can make or break the operation of an electromechanical slot machine. This is usually caused by a mechanical problem such as a malfunctioning reel motor or broken paper roll.
