Casino Terms – A Basic Guide

No matter the online casino game, part of understanding it fully is learning its lingo and specific terms. This can be overwhelming for many when rolling the dice and entering the casino world, and it can often feel like the deck is stacked against you.

But never fear. That is precisely why we have compiled this guide—so even beginner online slot players can grasp some of the simpler terms used in the gambling world before deciding whether to play or not. And because we know you may find this interesting, we’ll throw in a couple more advanced terms that will definitely not leave your head spinning like a roulette wheel.

Basic Casino Terms

Knowing these phrases will come in handy whether you’re playing at a reputable casino like Pokerstars or a land-based casino. 

Understanding the language used at the table will help you to feel more confident playing the games and make the overall experience more enjoyable.

House Edge

When a casino has a statistical edge over a player (and you will find this in varying degrees in every casino game), it is known as the house edge. Essentially, it is the percentage of each bet the casino expects to win over a period of time.

Wager

A wager refers to the action of placing a bet. It can be used in casino gaming environments and also in other areas, like sports betting.

Bet

A bet is simply the amount of cash you wager on a specific outcome in a casino game. It may also be known as your stake in the game.

Bankroll

The bankroll is the amount of money you have set aside to use at your chosen casino. As always, it should be an amount that has been specifically budgeted for the purposes of entertainment.

Jackpot

You may think this is an obvious term to include in our guide, but although you may know that the jackpot is the top prize a player wins (usually at a slot game), did you know there are different types of jackpots?

Dealer

A dealer is the person in charge of the game, usually a table game such as blackjack, roulette, or baccarat. They will either spin the wheel or deal the cards, and they are the staff member who controls the game. 

In live dealer roulette, for example, you may hear the dealer say, “No more bets, please,” indicating that players can no longer wager on the current game.

Volatility

Also known as variance, volatility refers to how often and how much a slot machine pays out. Low volatility means smaller, more frequent wins, while high volatility slots offer bigger wins that occur less often.

Payline

A payline is the line on which a payout will be awarded based on winning combinations. Older slot machines may only have one, while newer games can have hundreds.

Multiplier

Multipliers increase your winnings by a certain factor. If you win £10 and have a 2x multiplier, your payout is £20.

Free Spins

These are bonus rounds that allow players to spin the reels without placing a wager. They are often triggered by landing certain symbols or through promotional offers.

Bonus Round

A special feature within a slot or game that gives players extra chances to win, often with different rules or enhanced prizes. These can include mini-games, pick-and-win formats, or expanded reels.

Advanced Casino Terms

By now, we think you should be feeling pretty confident when it comes to the basic casino terms, so let’s up the ante (yet another casino term, basically meaning to up your bet).

Vigorish

This casino term even has its own slang: the “vig.” It is the fee a casino charges for taking a bet and also how the operator makes its money. It’s similar to the house edge, which is another way a casino turns a profit.

Random Number Generator (RNG)

RNG software is used in every legitimate and trustworthy casino to ensure all the games’ outcomes are fair and random.

Return to Player (RTP)

This is a gambling term that is used to describe the percentage of money a player can expect to win back over time. The higher the RTP, the better it is for players.

Wild Symbol

This symbol substitutes for others to help create a winning line, making it one of the most valuable symbols in many slot games.

Scatter Symbol

Scatters usually trigger bonus features like free spins or jackpot rounds, regardless of their position on the reels.

Casino Terms Aced

See, that wasn’t so bad, was it? Now, you are equipped with a little more knowledge when it comes to the world of gambling and gaming, and you know what they say: knowledge is power.

Next time you’re spinning reels or playing cards at an online casino, you’ll be able to recognise more than just the gameplay—you’ll understand what’s being said, what’s being offered, and how each feature functions.

Learning casino terminology isn’t about memorising jargon—it’s about feeling more confident and informed so that you can focus on enjoying the game, whether you’re playing casually or aiming for that big win.
