Glossary

Casino terminology can feel like a different language the first time you encounter it — especially if you're coming to online tables fresh or moving from pokies into live games and tournaments. At 21Bit, the language you'll run into covers everything from pokies maths to poker hand rankings to tournament structures and account rules. This glossary covers it all in plain Australian English, with AU$ examples throughout so the numbers actually mean something.

What are the key pokies terms Aussie players need to know?

Pokies have their own vocabulary built around the mathematical structure of the games. Understanding it before you spin changes every decision you make — from which title you choose to how you interpret what's happening mid-session.

RTP (Return to Player) — the theoretical percentage a pokie returns to players across a massive number of spins. A 96% RTP means AU$96 returned per AU$100 staked over time. This is a long-run maths average, not a session promise. Every game's RTP is in the info panel at 21Bit and independently audited under licensing requirements.

Volatility — how a pokie distributes its payouts. Low volatility means frequent small wins. High volatility means long dry spells with rare bigger hits. Neither is better — it comes down to your session length, bankroll, and how much variance you can sit through without going off your head. A high-volatility pokie on a short session is a completely different proposition from the same game run over thousands of spins.

Megaways — Big Time Gaming's licensed mechanic where each reel shows a random number of symbols every spin, generating up to 117,649 ways to win. Inherently high variance. Loads of providers have licensed it, so you'll find Megaways titles right across the lobby.

Wild — substitutes for most other symbols to complete winning combinations. Expanding wilds cover full reels; sticky wilds hold position across multiple spins; multiplier wilds boost win values of combinations they complete.

Scatter — pays regardless of reel position and typically triggers bonus rounds or free spins. Doesn't need to follow a payline to count.

Bonus buy — lets you skip straight to the bonus round by paying 50–100× your base stake. Check whether it's available in Australia before you look for it — some jurisdictions have knocked it on the head.

Max win cap — the maximum payout a single spin can deliver, expressed as a multiplier of stake. Becomes relevant when comparing high-variance titles. A AU$1 spin on a 5,000× max-win pokie pays out a maximum of AU$5,000 regardless of what the reels display.

Author's tip from Mia Thompson, Online Casino Specialist: "Always check the RTP and volatility before you load a pokie — not after. The info panel is sitting right there. Two titles can sit side by side in the lobby with similar themes and completely different maths profiles. Thirty seconds before you spin changes what you're expecting and how you manage your AU$ across the session."

What poker and table game terms come up most at 21Bit?

Live casino at 21Bit runs on Evolution's infrastructure, which means the table game range is serious — multiple blackjack variants, baccarat formats, several roulette types, and poker tables covering Three Card Poker, Casino Hold'em, and Ultimate Texas Hold'em. If you're coming from pokies into live tables, or picking up poker for the first time, these are the terms that come up most and are worth getting your head around before you sit down.

House edge — the mathematical advantage the casino holds over every game, expressed as a percentage of each bet. Blackjack with basic strategy: under 0.5%. Baccarat banker bet: 1.06%. European roulette: 2.7%. The lower the house edge, the more value you get from every AU$ you put through the game. It's the single most useful number when choosing which game to play.

Basic strategy — in blackjack, the mathematically optimal play for every hand-and-dealer-upcard combination. Following it consistently brings the house edge down to its lowest achievable level. It's a decision framework, not a guarantee — but it's the correct default call every single time.

Banker bet — in baccarat, the bet with the lowest house edge (1.06% after commission). Despite the 5% commission on wins, it beats the player bet (1.24%) on the maths. Tie bets carry a house edge above 14% — give them a wide berth.

Ante bet — in poker variants like Three Card Poker and Casino Hold'em, the mandatory bet placed before cards are dealt. You then decide whether to continue (raise or call) or fold based on your hand. The ante is the entry cost to each hand.

Raise / call / fold — the three core decisions in poker variants. Raising means increasing the bet; calling means matching the current bet; folding means surrendering the hand and losing the ante. Knowing when to fold a weak hand is as important as knowing when to raise a strong one.

Community cards — in Hold'em variants, the shared cards dealt face-up on the table that all players use to complete their best five-card hand. In Casino Hold'em, five community cards are used alongside each player's two hole cards.

Payout table — the schedule showing what each winning hand pays at a particular game. Payout tables vary between variants — always check before you sit down. A pair in one poker variant might pay 1:1; in another it might not pay at all.

House Edge Comparison — Table Games at 21Bit House edge by game and bet type — AU$100 cost comparison Lower bar = better value for your AU$ · Green = best available · Red = avoid 0% 2% 4% 6% 8% 10% 12% 14% 16% House edge % (lower is better for the player) Blackjack (basic strategy) 0.50% — AU$0.50 per AU$100 French roulette (La Partage) 1.35% — AU$1.35 per AU$100 Baccarat — banker bet 1.06% — AU$1.06 per AU$100 Baccarat — player bet 1.24% — AU$1.24 per AU$100 European roulette 2.70% — AU$2.70 per AU$100 Casino Hold'em (optimal) 2.16% — AU$2.16 per AU$100 American roulette 5.26% — AU$5.26 per AU$100 ⚠

Author's tip from Mia Thompson, Online Casino Specialist: "The house edge chart above is the most useful single piece of information on this page. If you're going to spend AU$500 on live casino sessions, the difference between playing blackjack with basic strategy (AU$2.50 expected cost) and American roulette (AU$26.30 expected cost) is real money. Choose your game based on the numbers, not the vibe of the lobby."

What tournament terms do you need to understand before entering?

Tournaments at 21Bit add a layer of structure on top of regular play — leaderboards, prize pools, scoring systems, and time windows. The terminology is specific enough that entering without understanding it can mean you play the format wrong entirely. These are the terms that come up most and matter most to your strategy.

Leaderboard — the ranked list of players in a tournament, ordered by score. Your position determines what you win at the end of the event window. In most open-format tournaments, only the top 10–50 positions receive a payout.

Scoring method — how your tournament points are calculated. The two main formats are: biggest single win multiplier (favours high-volatility pokies and chasing rare big hits) and total points accumulated (favours consistent play at a steady stake over the duration). These require completely different approaches.

Buy-in — the entry fee for paid tournament formats like sit-and-go events. Usually AU$5–AU$20. Free-entry tournaments have no buy-in; the trade-off is larger player pools and more competition for each paid position.

Re-entry — some tournaments allow you to re-enter after being knocked off the leaderboard, either free or for an additional buy-in. Check whether re-entry is available and how many times it's permitted before entering a competitive event.

Minimum stake — the lowest bet per spin or hand that earns tournament points. Playing below this threshold in an eligible game won't contribute to your leaderboard score. Always check this before you start — it's easy to miss in the event terms.

Prize pool breakdown — the distribution of the total prize pool across paid positions. Most tournaments heavily weight the top three positions. A AU$10,000 pool might pay AU$4,000 to first, AU$2,000 to second, and AU$1,000 to third, with the remainder split across lower positions. Understanding the breakdown tells you whether it's worth pushing for a top-three finish or if a lower paid position is more realistic.

What account and payment terms should every Australia player know?

The account side of online casino is mostly borrowed from financial services regulation — which is why it can feel unfamiliar at first. These are the terms you'll hit at 21Bit during registration, verification, and any time you're moving AU$ in or out. For a full step-by-step walkthrough of verification and account setup, the login page covers all of it without the runaround.

Term Category Plain meaning When you'll see it Notes
KYC Compliance Identity verification process Registration, first withdrawal Submit on day one — don't wait for first cashout
AML Compliance Anti-money laundering checks Higher deposit thresholds Source of funds docs may be requested in Australia
Wagering requirement Bonuses Times bonus must be staked before cashout All bonus offers Capped at 10× under Australia regulations
Deposit limit Responsible gambling Cap on AU$ added per day, week, or month Account settings Set before first deposit; 24hr delay to increase
Pending withdrawal Payments Withdrawal requested but not yet released After requesting cashout KYC must be complete before AU$ releases
POLi Payments AU open-banking direct payment method Deposit and withdrawal Popular Aussie option; no e-wallet account needed
Reality check Responsible gambling In-session alert showing time and AU$ spent During active sessions Set a sensible interval and switch it on
Self-exclusion Responsible gambling Long-term or permanent account closure On request Minimum 6 months; covers all licensed Australia operators
Source of funds Compliance Docs confirming where your deposited AU$ came from Higher spend accounts Payslips or bank statements; regulatory requirement

Author's tip from Mia Thompson, Online Casino Specialist: "The responsible gambling tools at 21Bit are only useful if you engage with them before you reckon you need them. Set a deposit limit at registration — even a generous one — and turn on reality checks. Those decisions made before your first session are almost always more sensible than anything you'd be willing to set mid-game."

Where do you go from here?

If the terminology is sorted and you're ready to look at the platform, the home page has a full breakdown of 21Bit — tournament schedule, game library, payments, and how it stacks up against other licensed options in Australia. For anything to do with getting your account registered, verified, or back into after a lockout, the login page covers the whole process step by step.

Understanding the terms before you play changes every decision you make — from which game you sit down at, to which tournament format suits your style, to how you use the platform's tools to keep your AU$ sessions within the limits you've actually set for yourself. Gambling is entertainment for adults who are 18 and over. The more clearly you understand the environment, the better that entertainment holds up over time.

FAQ

What is the meaning of RTP in casino games?
RTP stands for Return to Player. It’s the percentage of all wagered money a game is expected to return to players over time. For example, a game with an RTP of 95% will return £95 for every £100 wagered, on average.
What does volatility mean in slots?
Volatility refers to how often a slot game will pay out and the size of those payouts. Low volatility games offer smaller, frequent wins, while high volatility games tend to have bigger payouts but less often.
What are wagering requirements for bonuses?
Wagering requirements are how many times you need to wager the bonus amount before you can withdraw any winnings. For example, if you get a £10 bonus with 30x wagering, you’ll need to bet £300 before you can cash out.
What is the difference between sticky and cashable bonuses?
Sticky bonuses can't be withdrawn but can only be used for gameplay. Cashable bonuses, on the other hand, can be withdrawn once the wagering requirements are met.
How do I understand terms like "scatter" or "wild"?
In slots, "wild" symbols can substitute for other symbols to help form winning combinations, while "scatter" symbols often trigger bonus features, like free spins or extra rounds. Knowing these terms helps you make the most of your gameplay.
