Casino language can feel like a private club's slang. Terms fly around in promotions, game screens and chat, and a misread word can cost you money. This glossary collects forty of the most common ones, grouped so you can find them quickly. Definitions are general; for any specific offer or game, the rules on the brand's own site are what count.

Money and odds

These ten words appear on bet slips, game screens and promotion pages. Understanding them helps you plan your stake and understand what a price really says. For worked examples, see our cricket odds guide.

Remember that definitions are simplified. Where a number matters, read the specific rules.

TermPlain meaning
BankrollThe total money you set aside for gaming.
StakeThe amount you bet on one round or spin.
Bet slipThe panel that shows your selections and potential return.
OddsThe price that tells you the payout for a bet.
Decimal oddsOdds shown as the total return per unit staked.
Implied probabilityThe chance suggested by a price.
MarginThe built-in sportsbook cut inside prices.
House edgeThe average share of bets a game keeps over time.
RTPReturn to player, a long-run theoretical percentage.
VolatilityHow wide the swings are between wins and losses.

Slot words

Slots come with their own vocabulary. Most of it is explained in each game's info screen, but knowing the basics makes that screen far easier to read. Our slots hub covers the practical side of browsing the lobby.

If a word on a game screen is not in this list, look at the paytable first.

TermPlain meaning
PaytableThe game screen listing symbol values and rules.
PaylineA line on which matching symbols pay.
ReelA vertical column of symbols in a slot.
ScatterA symbol that often triggers a bonus anywhere on screen.
WildA symbol that substitutes for others.
MultiplierA factor that increases a win.
Free spinsSpins awarded without a new stake.
CascadeWinning symbols clear and new ones fall in.
JackpotA top prize, fixed or progressive.
ProgressiveA prize pool that grows with bets.

Table and live game words

Live and table games borrow words from card rooms and dice tables. A few of them, like push and bust, decide whether you win, lose or get your stake back, so they are worth learning. See the live casino hub for the games themselves.

If a table uses a term differently, the rules panel overrides this list.

TermPlain meaning
AutoplayA setting that spins repeatedly for you.
Demo modePractice play with pretend credits.
Live dealerA real host streamed from a studio.
Table limitsMinimum and maximum bets at a table.
Side betAn optional extra bet on a table game.
PushA tie where the stake is returned.
AnteA small forced bet to start a hand.
BustGoing over the limit, as in blackjack.
BankerOne of the two hands in baccarat.
TieA level result in a card or dice game.

Bonus and account words

Terms around bonuses and accounts matter most, because misunderstanding them can mean a bonus you cannot withdraw or a delay you did not expect. Read the real terms on the brand's site before you rely on any word here. Our wagering requirements guide gives a worked example.

Keep this page handy, and when in doubt ask support through the brand's official site.

TermPlain meaning
Wagering requirementTurnover needed before bonus winnings can be withdrawn.
TurnoverThe total amount wagered over a period.
CashbackA refund of part of your losses or bets.
RebateA return of a share of turnover.
Promo codeA code entered to claim an offer.
VerificationConfirming identity before certain actions.
CashierThe section for deposits and withdrawals.
WithdrawalMoving funds from your account to your own wallet or bank.
Stop-lossA loss limit set before play.
Self-exclusionA request to block your own access for a period.

Using the glossary well

Use this list as a bookmark rather than a lesson. When a promotion or game screen uses a word you do not recognize, look it up before you act. If it is not listed, ask support or skip the offer.

Also be wary of words that sound friendly but hide cost, such as free, bonus or boost. Free spins still have rules; a bonus may carry wagering. Good habits start with good vocabulary. For limit tools and warning signs, visit our responsible gaming page.

In short: know the word, read the rule, then decide.

Your questions, answered

Why do casinos use so many special terms?

Many words come from card rooms and dice tables, and online games added their own.

Are these definitions the same everywhere?

They are general. Each game and site can add details, so read the actual rules.

What is the most important term for bonuses?

Wagering requirement, since it decides whether bonus winnings can be withdrawn.

What does RTP tell me?

A long-run, theoretical return, not what will happen in your session.
