Casino Glossary: Casino, Pokies and Online Casino Terms Explained

A casino glossary is a reference list of the jargon used in casinos, pokies and online gambling, with each term explained in plain English. This glossary covers the terms Australian players are most likely to see on game screens, in paytables, in bonus terms and conditions and at the cashier.

It is organised by topic rather than as one long A–Z list. If you’re reading a pokie paytable, go to the pokies section. If you’re trying to understand a bonus offer, go to the bonus terms. The maths terms come first because many other definitions depend on them.

How to Use This Casino Glossary

Casino terms fall into a few distinct groups, and the same word can mean different things in different places. “Hand” means something different in blackjack than in poker. “Spin” means one thing on a roulette wheel and another on a pokie. Knowing which context you’re in avoids most confusion.

The sections below cover:

• Casino maths terms: RTP, house edge, odds, volatility and related concepts
• Pokies glossary: reels, paylines, Wilds, Scatters, jackpots and features
• Table game terms: blackjack, roulette, baccarat, poker and video poker
• Live dealer, crash and instant game terms
• Online casino terms: accounts, verification, payments and technology
• Bonus terms: wagering requirements, game weighting and restrictions
• Responsible gambling terms: limits, cool-offs and self-exclusion
• Commonly confused terms and myth-based jargon

Casino Maths Terms

These terms describe how games pay and how much risk they carry. They are the most useful words in any casino terms glossary, because they appear across pokies, table games and bonus conditions, and they are often misused.

• RTP (Return to Player): The percentage of total money wagered that a game is designed to pay back to players over a very large number of plays. A game with a 96% RTP is designed to return $96 for every $100 wagered on average, across an enormous volume of bets. It does not predict what happens in one session.
• House edge: The casino’s built-in mathematical advantage, expressed as a percentage of each bet. For games that publish RTP, house edge is roughly 100% minus RTP. A 96% RTP game has a 4% house edge.
• Probability: How likely an outcome is, usually shown as a fraction or percentage. On a European roulette wheel, the probability of any single number landing is 1 in 37, or about 2.7%.
• Odds: Another way of expressing likelihood, usually as a ratio of losing outcomes to winning outcomes. The true odds against a single number on European roulette are 36 to 1.
• Payout: What a winning bet actually pays under the game rules. A straight-up roulette bet pays 35 to 1. The gap between the true odds (36 to 1) and the payout (35 to 1) is where the house edge comes from.
• Expected value (EV): The average amount you’d theoretically win or lose per bet if the same bet were repeated many times. Casino bets almost always have negative EV for the player.
• Variance: The mathematical spread of results around the expected value. High variance means results swing further from the average in both directions.
• Volatility: The practical, player-facing description of variance, commonly used for pokies. Low-volatility games tend to pay smaller amounts more often. High-volatility games tend to pay less often but can produce larger individual wins. Volatility describes the pattern of results, not the overall return.
• Hit frequency: How often a game produces any winning result, often shown as a percentage or “1 in X spins”. A win smaller than your stake still counts as a hit.
• Turnover: The total amount wagered, including money won and re-bet. A $100 balance can generate several hundred or several thousand dollars in turnover, depending on how long you play.

Worked Example: Expected Value on Roulette

Take a hypothetical $10 straight-up bet on European roulette:

• Chance of winning: 1/37, with a profit of $350 (35 to 1)
• Chance of losing: 36/37, with a loss of $10

EV = (1/37 × $350) − (36/37 × $10) = ($350 − $360) ÷ 37 ≈ −$0.27 per bet

That works out to −2.7% of the stake, which matches the European wheel’s house edge. Any single spin still produces either a $350 win or a $10 loss. The −$0.27 only appears as an average over many spins.

Worked Example: RTP and Turnover

If a hypothetical pokie has a 96% RTP and you turn over $1,000 across a session, the theoretical average cost is $40. That figure is a long-run average, not a forecast. In a single session you might lose your whole budget or finish ahead. RTP describes the game’s design, not your result.

Pokies Glossary

“Pokies” is the Australian term for slot machines, short for “poker machines”. In Australian regulation, land-based pokies are usually called EGMs (electronic gaming machines). Online, the same games are often labelled “slots” by international providers.

Layout and Ways to Win

• Reels: The vertical columns of symbols that spin. Most modern video pokies use five reels, though three-reel and six-reel formats are common too.
• Rows: The horizontal positions visible on each reel. A “5×3” game has five reels and three rows.
• Payline: A fixed path across the reels on which matching symbols must land to pay. Games may have anywhere from one to 100 or more paylines.
• Fixed paylines vs adjustable paylines: Some games let you choose how many lines to play. Others have every line active on every spin.
• Ways to win: A system where matching symbols pay if they land on adjacent reels, usually starting from the leftmost reel, in any row position. “243 ways” and “1,024 ways” are common examples.
• Megaways: A trademarked mechanic licensed from Big Time Gaming, in which the number of symbols per reel changes on each spin, so the number of ways to win changes too.
• Cluster pays: Wins are formed by groups of matching symbols touching each other horizontally or vertically, rather than along lines.
• Paytable: The in-game information screen showing symbol values, feature rules and often the game’s RTP. Checking it is the most reliable way to understand a specific pokie.

Symbols

• Wild: A symbol that substitutes for other symbols to help complete wins. It usually cannot replace Scatters or bonus symbols.
• Expanding Wild: A Wild that grows to cover a whole reel.
• Sticky Wild: A Wild that stays in place for several spins, typically during free spins.
• Walking or shifting Wild: A Wild that moves one position on each subsequent spin.
• Scatter: A symbol that pays or triggers a feature regardless of where it lands, rather than needing to sit on a payline.
• Bonus symbol: A symbol that triggers a specific bonus round. In some games the Scatter and bonus symbol are the same thing.
• High-pay and low-pay symbols: Low-pay symbols are often card ranks (A, K, Q, J, 10). High-pay symbols are usually themed characters or objects.

Features and Mechanics

• Base game: Regular spins outside any bonus feature.
• Free spins: A feature awarding spins at no additional cost, often with added modifiers such as multipliers or extra Wilds.
• Retrigger: Landing the trigger symbols again during free spins to earn more spins.
• Multiplier: A value that multiplies a win, such as 2× or 5×.
• Cascading reels / tumble / avalanche: Winning symbols disappear and new ones drop into place, allowing multiple wins from one paid spin.
• Hold and win / cash collect: A feature where special symbols lock in place and respins reset when new ones land. Formats vary between providers.
• Bonus buy / feature buy: An option to pay a set multiple of your stake to trigger a feature immediately. Availability varies by jurisdiction, operator and game, and the price is typically high relative to a normal spin.
• Gamble feature: An optional double-or-nothing style game after a win, such as guessing a card colour.
• Max win: The largest amount a game can pay on a single spin or feature, usually expressed as a multiple of the stake (e.g. “5,000×”). It is a ceiling, not an expectation.
• Near miss: When a result looks close to a big win, such as two jackpot symbols and a third just off the line. It does not mean a win is getting closer.

Jackpots

• Fixed jackpot: A top prize set at a defined amount or stake multiple.
• Progressive jackpot: A jackpot that grows as a portion of each qualifying bet is added to it, until someone wins it and it resets.
• Standalone / local progressive: The jackpot grows from play on one game or one venue’s machines.
• Network / wide-area progressive: The jackpot is fed by play across many casinos or venues, which is why these tend to grow larger.
• Seed amount: The value a progressive jackpot resets to after being won.

Controls

• Stake / bet level / coin value: Settings that determine how much each spin costs.
• Autoplay: Runs a set number of spins automatically. Some jurisdictions restrict or ban it.
• Turbo / quick spin: Speeds up spin animations, which also increases how much you can wager per hour.
• Demo mode / free play: Playing with virtual credits. Useful for learning how features work, though demo versions don’t always match the settings of real-money versions at every operator.

Blackjack Terms

• Hit: Take another card.
• Stand: Keep your current total and take no more cards.
• Double down: Double your bet in exchange for exactly one more card. Rules on which totals you can double vary.
• Split: Separate a pair into two hands, placing an additional bet equal to the original.
• Surrender: Give up the hand and get half your bet back. Not every table offers it.
• Blackjack / natural: An ace plus a ten-value card as your first two cards. It traditionally pays 3 to 2.
• 6:5 blackjack: Tables paying 6 to 5 on a natural instead of 3 to 2. This noticeably increases the house edge and is worth checking before you sit down.
• Soft hand: A hand containing an ace counted as 11 (e.g. ace-6 is “soft 17”).
• Hard hand: A hand with no ace, or with an ace that must count as 1.
• Bust: Going over 21, which loses the hand immediately.
• Push: A tie with the dealer. Your bet is returned.
• Dealer stands on soft 17 (S17) / hits soft 17 (H17): A table rule describing how the dealer plays soft 17. S17 is slightly better for the player.
• Insurance: A side bet offered when the dealer shows an ace, paying 2 to 1 if the dealer has blackjack. It is generally a poor bet for players using basic strategy.
• Basic strategy: The mathematically optimal decision for every player hand against every dealer upcard under specific rules. It reduces the house edge but does not eliminate it.
• Shoe: The device holding multiple decks in a multi-deck game.
• Card counting: Tracking the ratio of high to low cards remaining to adjust bets. It relies on shoe penetration and is ineffective against continuous shuffling machines and standard online RNG blackjack, where the deck is effectively reshuffled every hand.

Roulette Terms

• European roulette: A wheel with 37 pockets (1–36 plus a single zero). House edge: 2.70%.
• American roulette: A wheel with 38 pockets, adding a double zero. House edge: 5.26% on most bets.
• French roulette: A single-zero game that may include La Partage or En Prison, rules that return or hold half of even-money bets when zero lands, lowering the edge on those bets.
• Inside bets: Bets on specific numbers or small groups on the number grid. These have higher payouts and lower probability.
• Outside bets: Bets on larger groups such as red/black, odd/even, dozens or columns. These have lower payouts and higher probability.

• Call bets / announced bets: Named bets covering sections of the wheel, such as Voisins du Zéro or Tiers du Cylindre. They are common in European and French games.
• Racetrack: The oval betting layout that mirrors the wheel’s number order, used for placing call bets.
• Croupier: The dealer who runs the table.

Baccarat Terms

• Player and Banker: The two hands you can bet on. Neither refers to you or the casino. They are simply the names of the two positions.
• Tie: A bet that both hands finish with the same total. It usually pays 8 to 1 and carries a much higher house edge than Player or Banker.
• Natural: A two-card total of 8 or 9, which ends the round immediately.
• Third-card rule / drawing rules: Fixed rules deciding whether each hand receives a third card. The player makes no drawing decisions.
• Commission: The fee (traditionally 5%) taken from winning Banker bets, because the Banker hand wins slightly more often.
• No-commission baccarat: A variant that removes the commission but reduces the payout on certain Banker wins, such as a win with a total of 6.
• Punto Banco: The most common form of baccarat, where all drawing is automatic.
• Scorecards / roads (Big Road, Bead Plate): Displays tracking previous results. They record history only and have no predictive value.

Poker and Video Poker Terms

• Hand rankings: The order of poker hands, from high card up to royal flush.
• Video poker: A single-player machine game based on five-card draw, where you choose which cards to hold and which to discard.
• Hold / discard: Your decisions in video poker. Correct play is what determines how close you get to the game’s theoretical return.
• Paytable (video poker): The payout schedule for each hand. Small changes, such as how much a full house or flush pays, significantly change the return.
• “9/6” Jacks or Better: Shorthand for a paytable paying 9 for a full house and 6 for a flush per coin bet. Lower-paying versions (e.g. 8/5) return less.
• Casino poker / table poker: Games like Casino Hold’em or Three Card Poker where you play against the house rather than other players.
• Ante: A compulsory initial bet in many casino poker variants.
• Rake: The fee a venue takes from pots in player-versus-player poker.

Live Dealer, Crash and Instant Game Terms

• Live dealer / live casino: Real table games streamed from a studio or casino floor, with a human dealer and physical cards or wheels.
• Game show: Live, presenter-hosted games, often built around a money wheel with bonus rounds.
• Bet behind: In live blackjack, betting on another seated player’s hand when no seat is available.
• Crash game: A game where a multiplier rises from 1× until it “crashes” at a random point. You win if you cash out before the crash.
• Cash-out: Locking in your current multiplier in a crash game.
• Auto cash-out: A preset multiplier at which your bet cashes out automatically.
• Crash point: The multiplier at which a round ends. Each round’s crash point is independent of previous rounds.
• Provably fair: A cryptographic system, common in crypto-focused games, that lets players verify a result was generated as stated and wasn’t altered after the bet was placed. It verifies fairness of the draw, not that the game has a favourable return.
• Instant games / scratchies: Quick-result games such as online scratch cards, plinko or mines.

Online Casino Glossary: Accounts, Payments and Technology

• RNG (Random Number Generator): Software that produces the outcomes in digital games. Each result is independent of the last.
• Game provider / studio: The company that develops the game, as distinct from the casino that offers it.
• Operator: The company running the casino website and handling your account and money.
• Licence: Authorisation from a gambling regulator to operate. The strength of consumer protection depends heavily on which regulator issued it.
• KYC (Know Your Customer): Identity checks required before or during play, typically involving photo ID and proof of address.
• Verification / account verification: The process of confirming your identity and, sometimes, your payment method or source of funds. Incomplete verification is one of the most common causes of withdrawal delays.
• Cashier: The section of the site where deposits and withdrawals are made.
• Pending period: A window after you request a withdrawal during which it hasn’t yet been processed, and at some sites can still be reversed.
• Withdrawal limit: A cap on how much can be withdrawn per transaction, day, week or month. These are set by each operator.
• Minimum deposit / minimum withdrawal: The smallest transaction amounts allowed. These vary by site and payment method.
• E-wallet: A digital payment account used as an intermediary between your bank and the casino.
• Chargeback: A reversal of a card payment requested through your bank. Casinos typically treat these seriously and may close accounts.
• Terms and conditions (T&Cs): The operator’s rules for accounts, bonuses and payments. Bonus terms usually sit in a separate section.
• Geo-blocking: Restricting access based on a user’s location.
• Session: A continuous period of play, from logging in or starting to stopping.

Bonus Terms

Bonus conditions contain the densest jargon in any online casino glossary, and misunderstanding them is a common source of player complaints.

• Welcome bonus / sign-up bonus: An offer for new players, usually tied to a first deposit.
• Deposit match: A bonus matching a percentage of your deposit. A “100% match up to $200” on a $100 deposit adds $100 in bonus funds.
• No deposit bonus: Bonus funds or spins granted without a deposit, usually with tight limits on winnings.
• Wagering requirement / playthrough / rollover: The amount you must bet before bonus funds, or winnings from them, can be withdrawn.
• Game weighting / contribution: How much each game type counts towards wagering. Pokies often count 100%. Table games may count far less or nothing.
• Max bet rule: The largest stake allowed while a bonus is active. Breaching it can void the bonus and associated winnings.
• Max cashout / win cap: A limit on how much can be withdrawn from bonus winnings.
• Bonus expiry: The deadline to use a bonus or complete its wagering.
• Restricted / excluded games: Games you cannot play with bonus funds, or that don’t count towards wagering.
• Sticky bonus: Bonus funds that can be used for play but are removed at withdrawal.
• Non-sticky bonus: Your real money is used first, and the bonus only activates if that is lost. Real-money winnings can generally be withdrawn before the bonus is used, subject to the terms.
• Cashback: A percentage of net losses returned, sometimes as cash and sometimes as bonus funds with their own conditions.
• Free spins value: The stake per spin assigned to free spins, which determines what they’re actually worth.
• Bonus abuse: The operator’s term for behaviour that breaches bonus rules, such as multiple accounts. It is often defined broadly in T&Cs.

Worked Example: Wagering Requirements

Hypothetically, you receive a $100 bonus with a 35× wagering requirement:

• If wagering applies to the bonus only: 35 × $100 = $3,500 in bets required
• If wagering applies to deposit plus bonus ($200): 35 × $200 = $7,000 in bets required

If you play a table game with 10% contribution, a $100 bet only counts as $10 towards that total.

Wagering requirements interact directly with house edge. Every dollar wagered carries the game’s built-in cost, so large requirements make it statistically less likely that a bonus balance survives to withdrawal.

Responsible Gambling Terms

• Deposit limit: A cap on how much you can deposit over a set period.
• Loss limit: A cap on net losses over a set period.
• Session time limit: A maximum length of time you can play in one session.
• Reality check: A pop-up reminder showing how long you’ve been playing and, often, your net result.
• Cool-off / time-out: A short, self-selected break from an account, typically from a day to several weeks.
• Self-exclusion: A longer, formal block on gambling with an operator or group of operators, usually lasting months or years and difficult to reverse early.
• BetStop: Australia’s National Self-Exclusion Register, which covers licensed Australian online and phone wagering providers.
• Chasing losses: Continuing to gamble, or increasing bets, to win back money already lost. It is a recognised warning sign of gambling harm, not a strategy.
• Gambling Help Online: A free, confidential national Australian support service, available 24/7 online or on 1800 858 858.

Australian Casino Slang

• Pokies: Poker machines, meaning slot machines in Australian usage.
• Punter: A gambler or customer. The word is used for both betting and casino play.
• Having a slap: Informal slang for playing the pokies.
• The house: The casino or operator.
• High roller: A player who bets large amounts.
• VIP program / loyalty program: A rewards scheme based on turnover. Rewards are driven by how much you bet, not how much you win.
• Tilt: Borrowed from poker, meaning playing emotionally, often after losses.

Commonly Confused Casino Terms

Terms That Describe Myths

Some casino vocabulary describes beliefs that don’t hold up mathematically. It helps to recognise them.

• Hot / cold machine or number: The idea that a pokie or roulette number is on a streak. Independent random results have no memory.
• “Due” to pay: The belief that a machine that hasn’t paid recently is more likely to pay soon. RNG outcomes are independent, so recent history doesn’t change the next result.
• Gambler’s fallacy: The general error of believing past independent results influence future ones, such as expecting red after several blacks.
• Martingale: A system of doubling your bet after each loss. It doesn’t change the house edge. It concentrates risk into occasional large losses and can quickly hit table limits or exhaust a bankroll.
• Loose / tight pokies: Casual terms for machines believed to pay more or less. Actual return is set by game configuration and shown as RTP where published, not by timing or observation.

Getting the Most From Casino Terminology

A few habits make the jargon genuinely useful rather than decorative:

• Read the paytable and help screen before playing an unfamiliar game. It defines that game’s specific features, which can differ from the general definitions above.
• Check the actual numbers, not just the labels. “Free spins” means little without the spin value. “Match bonus” means little without the wagering terms.
• Don’t assume terms work the same across games or operators. Rules around surrender, doubling, bonus weighting and withdrawal limits all vary.
• Separate decisions from settings. Terms like basic strategy and video poker holds describe decisions that affect expected return. Stake size and limits affect how much you spend and how fast. Hot numbers and “due” machines affect neither.

Final Takeaway

Most casino jargon falls into three buckets: terms that describe how a game pays (RTP, house edge, volatility), terms that describe what you can do (hit, hold, cash out, set limits) and terms that describe conditions attached to your money (wagering, max bet, withdrawal limits). Once you know which bucket a term belongs to, it becomes much easier to judge whether it actually affects your results, your spending or neither.
