Casino Terms Explained: A Plain-English Glossary Every New Player Should Read First

Online casino terminology isn’t complicated — but the details matter. RTP, wagering requirements, volatility, sticky bonuses: these terms appear in game panels, bonus offers, and terms and conditions. Misunderstanding any one of them can cost you real money.

This glossary covers the 15 casino terms that have the most practical impact on new players — what they mean, why they matter, and what to actually do with the information.

Full Explanations: Casino Terms That Affect Your Money

RTP (Return to Player)

RTP is the percentage of all money wagered on a game that the game returns to players over time. A slot with 96% RTP will, across millions of spins, return $96 for every $100 wagered. The remaining $4 is the house edge.

The critical clarification: RTP is a long-run statistical figure, not a session guarantee. Short-term results are driven by variance. RTP tells you which games are calibrated more generously than others — and that information is genuinely useful for game selection.

Most reputable casinos publish RTP in the game information panel, allowing players to understand the expected long-term return of a game before they start playing. Slots featured under Richard Casino bonus codes typically display RTP alongside game rules and other important information, helping users make more informed decisions. If a casino doesn’t publish RTP figures, that absence is itself meaningful, as transparency is generally considered a sign of a trustworthy gaming platform.

House Edge

House edge is RTP expressed from the casino’s perspective. A game with 96% RTP has a 4% house edge. The two always add up to 100%.

House edge varies significantly by game:

• Blackjack with basic strategy: below 0.5%
• European roulette: 2.7%
• American roulette: 5.26%
• Slots: roughly 2–10% depending on variant

Volatility (Variance)

Volatility describes how a game distributes its returns — how frequently it pays, and in what amounts. It is entirely separate from RTP.

• High volatility: infrequent wins, larger amounts. Requires a larger bankroll to absorb losing runs
• Low volatility: frequent wins, smaller amounts. Gives limited budgets more playing time

A high-volatility and a low-volatility slot can share identical RTP while feeling completely different to play. Match volatility to your bankroll size and session goals, not just to the headline RTP figure.

Wagering Requirements (Playthrough)

Wagering requirements specify how many times you must bet a bonus before withdrawing winnings. A $100 bonus with 30x wagering means $3,000 in bets before withdrawal is possible.

This is the single most important number in any bonus offer. Always check two things before accepting:

• latter doubles the obligation
• What is the base RTP of the games allowed? High wagering on a low-RTP game can cost more than the bonus is worth

Check wagering requirements before opting in at platforms including Richard Casino.

Game Contribution Rate

Not all games count equally toward clearing a wagering requirement. Slots typically contribute 100%. Table games often contribute 10%, 20%, or nothing.

A 30x wagering requirement where your preferred game contributes 10% is effectively a 300x requirement. Always check the game contribution table in the bonus terms before opting in.

Sticky Bonus (Phantom Bonus)

A sticky bonus can never be withdrawn. Only winnings above the bonus amount are yours to keep.

Example: $100 sticky bonus, wagering complete, balance is $180. You withdraw $80 (your winnings). The $100 bonus disappears. Sticky bonuses still have value — they give you capital that can generate real winnings — but they work differently from non-sticky alternatives. Know which type you’re accepting before you opt in.

Free Spins

Free spins allow a set number of spins on specified games at no cost. Practical value depends on three factors:

• Spin value — typically $0.10 to $0.20 per spin
• Which game they’re restricted to — RTP of the game affects how much you retain after wagering
• Attached wagering requirement — no-wagering free spins, where winnings are credited as withdrawable cash, are the most straightforwardly valuable format

• Cashback

  Cashback returns a percentage of net losses over a defined period — typically weekly. The critical distinction is format:

  • Cash cashback: credited as withdrawable funds immediately
  • Bonus cashback: carries wagering requirements and should be evaluated like any other bonus

  The difference in real value between these two formats can be substantial despite identical percentage figures.

  Self-Exclusion

  Self-exclusion blocks your own access to a casino for a defined period. During exclusion: no account access, no deposits, no marketing. Increases require a cooling-off period, making the tool structurally effective rather than symbolic.

  For maximum protection, use both the individual platform tool and a national multi-operator scheme — GamStop in the UK extends exclusion across all licensed operators simultaneously.

  KYC (Know Your Customer)

  KYC is the identity verification process required before withdrawals. It typically involves government-issued ID, proof of address, and proof of payment method. Complete KYC early — before your first withdrawal — to avoid delays when you want to access funds. Platforms including Richard Casino and Stay Casino allow proactive KYC submission through account settings.

• Deposit Limit

  A deposit limit caps how much you can add to your account per day, week, or month. Reducing a limit takes effect immediately. Increasing one requires a cooling-off period — that delay is what makes the tool effective. Set your deposit limit based on what you’re genuinely comfortable spending, not on what you hope to win back.

  Maximum Bet Restriction

  Most bonuses include a maximum bet restriction while the wagering requirement is active — typically $5 per spin or hand. Exceeding this limit can void the bonus and all associated winnings, regardless of how much wagering you’ve completed. This restriction is consistently buried in bonus terms and consistently catches players out.

  Jackpot Types: Fixed, Progressive, and Must-Hit

  Three types to know:

  • Fixed jackpot: set amount, doesn’t change
  • Progressive jackpot: grows with each bet, can reach life-changing sums, but reduces base RTP
  • Must-hit progressive: guaranteed to pay before a specified ceiling — the only type where timing of play affects expected value

• Frequently Asked Questions: Casino Terms for New Players

  What is the difference between RTP and house edge?

  They’re the same figure from different perspectives. RTP is the player’s share; house edge is the casino’s. A game with 96% RTP has a 4% house edge. The two always sum to 100%.

  Is a 30x wagering requirement good or bad?

  It depends on whether it applies to the bonus alone or bonus plus deposit, and which games you can use to clear it. On slots with 96% RTP, a 30x requirement on a $100 bonus has an expected cost of around $120 — more than the bonus itself. Below 20x is generally considered competitive; above 40x is rarely worth accepting.

• What does volatility mean in practice for my bankroll?

  High-volatility games require more funds to ride out losing runs between significant wins. If your session budget is $50 or less, a high-volatility slot will likely exhaust it before you see the game’s full range of outcomes. Low-volatility games give limited bankrolls more playing time.

  Why do I need to complete KYC before withdrawing?

  Licensed casinos are legally required to verify player identity before processing withdrawals under anti-money laundering regulations. Completing KYC in advance — rather than at the point of withdrawal — avoids delays that can otherwise take several business days to resolve.

  Can a casino change the wagering requirement after I’ve accepted a bonus?

  No. The terms in place at the time you opt into a bonus govern that bonus. Changes to terms apply to future offers, not active ones. Screenshot or save the terms at the time of opting in — if a dispute arises, the terms at opt-in time are what matter.
