If you’re new to online casinos, some of the words used in games and promotions might seem confusing at first. Terms like RTP, wilds, wagering and paylines appear everywhere, but what do they actually mean?
We’ve put together this casino terminology guide to explain the most common casino words in simple English. Whether you’re exploring online slots, learning how blackjack works or trying to understand a casino bonus, you’ll find clear explanations and practical examples below.
Ways to Win
Ways to Win describes the number of possible symbol combinations that can produce a winning result on a slot machine. Unlike traditional slots, which use fixed paylines, these games often allow matching symbols to appear in different positions across neighbouring reels.
For example, a slot offering 243 ways to win has 243 possible symbol paths that could form winning combinations. You usually need matching symbols on consecutive reels, starting from the left, although the exact rules depend on the game.
A higher number of ways to win means more possible winning combinations, but it doesn’t automatically mean you’re more likely to make a profit.
Beginner’s Luck
Beginner’s Luck is a popular expression used when someone wins or performs surprisingly well the first time they try a casino game.
Imagine playing roulette for the first time and correctly guessing the winning number. Someone might call that beginner’s luck.
However, there’s no evidence that new players have better chances of winning. Casino games involving chance don’t recognise whether you’re a beginner or an experienced player. Every result depends on the game’s rules and probabilities, not how long you’ve been playing.
Poker
Poker is a card game where players compete to win a pot containing the money wagered during a hand. The objective is usually to create the strongest five-card combination or convince other players to fold.
Popular poker variations include Texas Hold’em, Omaha and Seven-Card Stud.
Unlike most slot games, poker involves a mixture of skill, strategy, decision-making and luck. Players must understand hand rankings, calculate risks and decide when to bet, raise, call or fold.
Some online casinos also offer poker-inspired games played against the house rather than other players.
Balance
Your Balance is the amount of money or playable funds currently available in your casino account.
For example, if you deposit £50 and place a £5 bet that loses, your balance will usually decrease to £45.
Online casinos may separate your funds into different categories:
- Cash balance: Money deposited or available as real cash.
- Bonus balance: Promotional funds that may have special conditions.
- Withdrawable balance: Money currently eligible for withdrawal.
It’s important to check these amounts separately, as bonus funds aren’t always available for immediate withdrawal.
Stake
A Stake is the amount of money you risk on a single bet, spin or game round.
For example, if you choose a £2 stake on an online slot, you’re risking £2 on that spin. If you place £10 on red in roulette, your stake is £10.
The stake affects how much money you could win or lose. In many casino games, larger stakes produce larger potential payouts, but they also increase the amount at risk.
Setting a comfortable stake before playing makes it easier to keep track of your spending.
Casino Tournament
A Casino Tournament is a competition where players compete against each other based on their performance in selected casino games.
Slot tournaments are particularly common. Participants might earn points for winning combinations, successful spins or other achievements during a specific period.
At the end of the competition, players are ranked on a leaderboard. Depending on the tournament rules, prizes may be awarded to the highest-ranking participants.
Some tournaments are free to enter, while others require an entry fee or real-money play. Always check how points are calculated, what prizes are available and whether any additional conditions apply.
Wager
A Wager is another word for a bet. It refers to money placed on an uncertain outcome, such as a roulette result, blackjack hand or slot spin.
You might also encounter the term wagering requirements when reading casino bonus conditions.
These requirements explain how much qualifying play is needed before certain bonus funds or winnings can be withdrawn.
For example, a £10 bonus with a 10x wagering requirement would require £100 in qualifying wagers. The exact calculation depends on the promotion, and not every game necessarily contributes equally.
Free Spins
Free Spins are slot spins provided without charging the player a normal cash stake for each awarded spin.
They can appear as part of a casino promotion or as a feature triggered during a slot game.
For example, landing three special symbols might activate 10 free spins. During these spins, the game can award prizes without deducting an additional stake for each spin.
However, free spins aren’t always completely free of conditions. Promotional offers may include expiry dates, game restrictions or wagering requirements on winnings. Reading the terms helps you understand what you can actually receive.
Odds
Odds describe the relationship between the probability of an outcome and the potential payout offered for betting on it.
In casino games, odds can help you understand how likely an event is and what a successful bet might return.
For example, a bet offered at fractional odds of 2/1 would provide £2 in profit for every £1 staked if it wins, plus the original £1 stake.
It’s important to remember that payout odds aren’t always the same as the true mathematical probability of winning. Casino games normally include an advantage for the operator, known as the house edge.
Classic Slots
Classic Slots are traditional-style slot machines inspired by the original mechanical games found in casinos and amusement arcades.
They usually feature three reels, simple symbols and a small number of paylines. Common symbols include cherries, lemons, bells, lucky sevens and BAR icons.
Compared with modern video slots, classic slots generally have fewer bonus features and simpler game mechanics.
The basic idea is straightforward: choose a stake, spin the reels and look for winning symbol combinations. Their familiar design makes them easy to recognise, although the outcomes are still based on chance.
Bet
A Bet is money placed on a particular result in a casino game.
For example, placing £5 on black in roulette is a bet that the ball will land on a black-numbered pocket.
In blackjack, your bet is the money you put forward before the cards are dealt. In slots, pressing the spin button with a selected stake places a bet on that round.
The words bet, wager and stake are closely related. However, stake usually refers specifically to the amount risked, while a bet or wager describes the gambling action itself.
Win Both Ways
Win Both Ways is a slot feature that allows winning symbol combinations to form in two directions: from left to right and from right to left.
Most traditional slots only count combinations starting from the leftmost reel. With Win Both Ways, matching symbols beginning on the right may also qualify for a payout.
For example, three matching symbols appearing on the final three reels could produce a win if the game’s rules allow it.
The exact payment system varies between slots, so it’s worth checking the paytable to understand which combinations count.
Jackpot
A Jackpot is a large prize that can be won during a casino game, usually by achieving a particular combination or triggering a special feature.
In slot machines, a jackpot might be awarded for landing certain symbols or activating a dedicated bonus round.
Jackpots can be fixed or progressive. A fixed jackpot offers a predetermined prize amount, while a progressive jackpot can increase as qualifying bets are placed.
Although jackpot prizes can be substantial, they are usually difficult to win. A large advertised jackpot doesn’t mean that every player has a realistic chance of receiving it during a short session.
VIP
VIP stands for Very Important Person. In online casinos, the term usually refers to customers who receive access to a loyalty programme or special account benefits.
Depending on the operator, VIP programmes might include personalised customer support, loyalty rewards or exclusive promotions.
Some programmes use different membership levels based on qualifying activity, although the exact rules vary.
In the UK, operators must follow regulatory requirements when offering incentives and managing customer accounts. VIP membership doesn’t improve the mathematical odds of casino games, and players shouldn’t feel pressured to spend more simply to reach a higher status.
Wilds
Wilds are special symbols in slot games that can replace other symbols to help complete winning combinations.
Imagine a slot where three matching diamond symbols create a payout. If a wild symbol appears in place of one of those diamonds, it may still count towards the winning combination.
Wild symbols can have additional features, depending on the game. Some expand across entire reels, while others remain in position for several spins.
Not all wilds work in the same way, and they may not replace certain symbols, such as scatters or bonus icons. The game’s paytable explains their exact function.
Megaways™
Megaways™ is a slot game mechanic developed by Big Time Gaming. Its main feature is a changing number of symbols on each reel, which creates a different number of potential winning combinations on every spin.
Traditional slot machines normally have a fixed reel layout. Megaways games can change the reel heights from one spin to another.
Many Megaways slots offer up to 117,649 ways to win, although some games feature different maximums and additional mechanics.
The number of ways is calculated from the symbols visible across the reels. More possible combinations don’t guarantee frequent payouts or better overall returns.
Pick to Win
Pick to Win is a bonus feature where players select objects on the screen to reveal hidden prizes.
For example, a slot might display six treasure chests. You choose one or more chests, and each selection reveals a cash prize, multiplier, free spins or another reward.
This feature makes the bonus round feel more interactive because the player takes part in revealing the result.
However, the outcome is still governed by the game’s programmed rules and randomisation system. In some games, the prize may already be determined before the player makes a selection.
Return to Player Rate (RTP)
Return to Player (RTP) is a percentage showing how much of the money wagered on a casino game is theoretically returned to players as winnings over a very large number of rounds.
For example, a slot with a 96% RTP is designed to return an average of £96 for every £100 wagered across extensive play. The remaining 4% represents its theoretical house edge.
This doesn’t mean you’ll personally receive £96 back after spending £100. During a short session, you could win more, win less or lose your entire stake.
RTP is a long-term statistical measure, not a prediction of individual results.
Blackjack
Blackjack is a casino card game where the aim is to beat the dealer by achieving a hand value closer to 21 without going over.
Number cards are worth their printed values, picture cards count as 10, and an ace can count as either 1 or 11.
Players generally have the option to take another card, known as hit, or keep their current hand, known as stand.
Other actions, such as doubling down or splitting pairs, may also be available. Understanding these decisions can influence your chances, but blackjack still involves risk and no strategy guarantees a win.
Bonus Feature
A Bonus Feature is an additional game element that offers something beyond the standard casino gameplay.
In online slots, bonus features often include free spins, special symbols, extra reels, multipliers or interactive prize rounds.
For example, collecting three bonus symbols might open a new screen where the player selects objects to reveal prizes.
Some bonuses activate randomly, while others require a particular combination of symbols.
Bonus features can change the size and frequency of payouts, but they don’t guarantee that the player will finish with more money than they started with.
Multiplier
A Multiplier is a feature that increases a winning amount by a specified number.
Multipliers are usually shown as 2x, 3x, 5x or higher.
For example, if a slot produces a £4 win with a 3x multiplier, the resulting payout would be £12.
Multipliers can appear during regular spins, free-spin rounds or special bonus features. Some apply to individual symbol combinations, while others affect the total winnings from a round.
A higher multiplier can increase a prize, but it only has value when the conditions required by the game are met.
Random Number Generator (RNG)
A Random Number Generator (RNG) is a computer system used to produce unpredictable outcomes in digital casino games.
In online slots, the RNG determines the result of each spin. In digital roulette, it can select the winning number, while in certain card games it helps determine the order of cards.
The important point is that previous results don’t predict what will happen next in an independently random game.
For example, losing ten slot spins in a row doesn’t mean the next spin is more likely to win.
RNG-based casino games offered by licensed UK operators are subject to technical standards and testing requirements.
Banker
Banker is a term used in several casino card games, particularly baccarat.
In standard baccarat, the Banker is one of the two hands dealt during each round. Players can bet on the Banker hand, the Player hand or a tie.
The Banker isn’t necessarily the casino employee dealing the cards. It’s simply the name given to one side of the game.
In some other card games, the banker refers to the person or position responsible for covering bets and paying winnings.
The exact meaning depends on the game being played.
Cash Out
Cash Out generally means taking money or value out of an active bet or gambling position.
In sports betting, Cash Out commonly refers to accepting a settlement before an event has finished. The operator offers an amount based on the current situation, which may be higher or lower than the original stake.
In casino settings, the phrase may also refer to collecting remaining credits or transferring playable funds back to an account balance.
Cash Out is sometimes confused with withdrawal, but the two aren’t always the same. Withdrawing means transferring available money from the casino account to an external payment method.
Dealer
A Dealer is the person responsible for running a casino table game, distributing cards, handling equipment and managing bets.
In blackjack, the dealer gives players their cards and plays according to the rules of the table. In roulette, the dealer manages the betting process and announces the winning result.
Online live casinos use real dealers who appear through a video stream.
Dealers don’t simply decide who wins. They follow established rules and procedures designed to keep the game running correctly.
Scatter
A Scatter is a special slot symbol that can trigger prizes or bonus features without needing to land on a traditional payline.
For example, a game might award 10 free spins when three scatter symbols appear anywhere on the reels.
Unlike ordinary symbols, scatters often don’t need to appear next to each other or follow a specific sequence.
Some slots also offer cash prizes for collecting particular numbers of scatter symbols.
The exact conditions depend on the game, so it’s useful to check how many scatters are required and where they need to appear.
Baccarat
Baccarat is a card game where players predict which of two hands will finish closest to a total value of nine.
The hands are called Player and Banker. You can normally bet on either hand winning or on the result being a tie.
Cards from two to nine count at face value, aces count as one, and tens and picture cards count as zero. If the total exceeds nine, only the final digit is used.
Baccarat is largely based on chance because the drawing rules determine how the hands are played. Winning Banker bets often have a commission or an adjusted payout, depending on the variation.
Craps
Craps is a dice game played with two dice. Players bet on the results of individual rolls or sequences of rolls.
The main betting option is the Pass Line, which begins with a roll called the come-out roll.
If the first roll produces 7 or 11, the Pass Line bet wins. If it produces 2, 3 or 12, the bet loses.
Other results establish a point, which must be rolled again before a seven for the Pass Line bet to win.
Craps may look complicated because of its many betting options, but the basic rules become easier to understand once you learn how the point system works.
Download
In casino terminology, Download means transferring casino-related software or an application to your device.
Some online casinos offer mobile apps or desktop programmes that allow users to access games without opening a standard web browser.
However, many modern casino platforms use browser-based technology, so downloading additional software isn’t always necessary.
Before installing a casino application, make sure it comes from an official and trustworthy source.
Downloading an app doesn’t change the odds of winning. It simply provides another way of accessing the casino platform.
Croupier
A Croupier is a casino employee who manages table games, particularly roulette, although the word can also be used for other casino games.
At a roulette table, the croupier accepts bets, spins the wheel, announces the result and arranges payouts.
The term is commonly associated with traditional European casinos, while dealer is often used more broadly.
In practice, the responsibilities can overlap.
Online live casino games may also feature professional croupiers who manage physical tables while players participate through a video connection.
Gamble Feature
A Gamble Feature is an optional slot feature that allows players to risk certain winnings for a chance to increase them.
For example, after receiving a £5 win, a game might offer a card-colour guessing challenge. Guessing correctly could double the amount, while an incorrect guess could result in losing the £5.
Some games offer several gamble levels, while others limit how often the feature can be used.
Not every casino or slot offers this option, and availability can vary by market. The feature introduces additional risk rather than creating guaranteed extra winnings.
Withdrawal
A Withdrawal is the process of transferring available money from your online casino account to a payment method, such as a bank account or supported e-wallet.
For example, if your withdrawable balance is £100, you might request to transfer £60 to your bank.
Withdrawal times depend on the casino, payment method and any necessary account checks.
Before processing a request, the operator may need to complete identity verification or review applicable bonus conditions.
It’s worth checking minimum withdrawal amounts, processing times and any relevant restrictions before making a request.
Live Gaming
Live Gaming, also called live dealer gaming or live casino, allows players to participate in casino games hosted by real people through a video stream.
Instead of watching computer-generated cards or roulette wheels, players can see a physical table and follow the action in real time.
Popular live games include blackjack, roulette, baccarat and certain poker-based formats.
Players place bets using the casino’s digital interface, while the dealer manages the physical game.
Live gaming creates a more traditional casino atmosphere, but it doesn’t remove the house edge or guarantee better results.
Progressive Jackpot
A Progressive Jackpot is a casino prize that increases over time as qualifying wagers contribute to the prize pool.
Unlike a fixed jackpot, which remains at a set amount, a progressive jackpot can continue growing until someone wins it.
For example, a jackpot might begin at £10,000 and increase gradually as eligible players take part.
Some progressive jackpots are linked to one game, while others connect multiple slot machines or casinos.
After the jackpot is won, it normally resets to a starting amount. Large progressive prizes can be appealing, but the chances of winning them may be extremely small.
Tumble
Tumble is a slot feature where winning symbols disappear after a successful combination, allowing new symbols to fall into the empty spaces.
This creates an opportunity for another winning combination without requiring a separate paid spin.
For example, five matching symbols might produce a £3 win. Those symbols then disappear, new ones drop into place, and another combination could generate an additional £2.
The process can repeat until no new winning combinations appear.
Tumble mechanics are also known as cascading reels or avalanche features, depending on the game developer.
Edge
Edge usually refers to the mathematical advantage one side has over another. In casino games, the most common example is the house edge.
The house edge represents the average percentage of wagers that the casino expects to retain over a large number of rounds.
For example, a game with a theoretical house edge of 2% is expected to retain approximately £2 for every £100 wagered over the long term.
This doesn’t mean every player loses exactly 2% of their money. Short-term results can vary considerably.
Understanding the house edge helps explain why casino games are designed to generate revenue for the operator over time.
Roulette
Roulette is a popular casino game where players predict where a small ball will land on a spinning numbered wheel.
Players can bet on individual numbers, groups of numbers, colours, odd or even results and other combinations.
European roulette uses 37 pockets numbered from 0 to 36. American roulette includes an additional 00 pocket, which increases the house edge on standard bets.
For example, placing £5 on red in European roulette provides an even-money payout if a red number wins.
Roulette is based on chance, and previous spins don’t influence the next result on a fair, independent wheel.
