A Glossary of Slot Terms to Help You Succeed at Online Casinos

A slot is a slit or narrow opening, especially one for receiving something, such as a coin or letter. A slot is also a position or assignment in a game, such as a player’s place on a team. The word slot is derived from the Latin phrase sclavium, meaning “a share or portion.” A common use of the word today is in reference to a computer or video card’s memory slot, which is used to store and retrieve data. The term can also be applied to the physical openings in a machine where coins are inserted.

Whether you’re new to the world of online casino games or a longtime pro, understanding the terms and language associated with slots can make your experience much more enjoyable. To help, we’ve put together this handy glossary of key slot terms to assist in your quest for casino knowledge.

Pay table

A pay table is a chart that displays the possible combinations of symbols on a slot machine and their corresponding payout amounts. This information is typically displayed above or below the reels on a traditional machine, while on modern machines it may be accessible via a help menu. Regardless of where it is found, a good pay table should be easy to read and visually appealing. A well-designed pay table will often feature graphics that match the theme of a particular slot, further helping to explain the game’s mechanics and rules.

Pay lines

The pay lines of a slot machine are the patterns that matching symbols need to land on in order for a win to occur. In many cases, a slot’s pay lines will be arranged in a way that maximizes the number of opportunities for winning combinations. A traditional slot may have a single payline, but more advanced machines may feature several different horizontal and vertical patterns that can create multiple potential winning opportunities with each spin.


The bonus features of a slot game can be an exciting part of the experience, but it’s important to remember that luck plays a huge role in the outcome of each spin. As such, it’s best to choose a slot machine based on personal preferences rather than solely on its return rate or other statistics. A great machine will successfully combine elements such as volatility, RTP, betting limits, and bonus features to provide the most enjoyable gaming experience.
