What Is a Slot?


A slot is a narrow opening in a machine or container, for example a hole that you put coins in to make the machine work. It also refers to a position in a group, series or sequence.

How Slots Work

A player places a certain number of credits on a slot machine and the reels spin. If symbols line up, the player wins. The amount the player wins depends on the type of slot machine and how win factors for individual symbols are configured.

Pay Table

A pay table lists all of the symbols that are available in a slot machine. It also gives instructions on special features, paylines and betting requirements.

Symbol Probability

Modern slot machines use microprocessors to determine how many times each symbol will appear on the reels, as well as the probability that it will appear in specific positions. This information helps to ensure that the slot machine will payout at a reasonable rate.

The Return to Player (RTP)

A slot machine’s RTP is one of the most important statistics that casino management can monitor. It’s a good indicator of how much the game will pay out to players, and it is a key factor in determining which machines to keep around.

The Paytable

A paytable is a handy guide that tells you how much you can win by matching specific symbols on a slot machine’s pay line. It is usually located on the face of the machine, and is particularly useful on older machines. It also provides information on bonus rounds and jackpots, as well as the winning combinations of symbols.
