Every term you will meet in a bonus footnote or a terms page, defined without spin.
The legal framework requiring operators to identify customers and report suspicious activity. It is why a casino advertising no verification can still demand documents at any moment: the obligation sits above its marketing.
A licence issued by the Autonomous Island of Anjouan. Among the least demanding gambling authorisations available, with limited practical recourse in a dispute.
A pre-set multiplier at which a crash bet settles automatically. It removes reaction time as a factor; it does not improve the odds.
The money set aside for gambling, separate from anything else. The useful question is not how much you could win with it but how many rounds it survives at your stake size.
A broad clause letting an operator void winnings for play it considers irregular: low-risk betting patterns, hedging opposite outcomes, or clearing a bonus in an unusual way. The definition is deliberately elastic, which is why reading it before you claim matters.
Paying a fixed multiple of your stake to enter a slot's bonus round immediately, typically 75 to 100 times. It buys volatility, not value: the RTP of a bought feature is roughly the same as reaching it naturally, and often slightly lower.
Taking the current multiplier in a crash-style game, or settling a sports bet before the event ends. In a crash game every cash-out point carries the same expected value.
A percentage of net losses returned over a period. When it is paid with no wagering attached it is the most transparent bonus type in the industry, because its value can be calculated exactly.
A value your own device contributes, and which you can usually change. It exists so the casino cannot control the outcome alone.
A slot mechanic that pays for groups of adjacent matching symbols rather than for symbols on a payline.
A wallet kept offline. The safest place for crypto you are not actively playing with, and the reason to withdraw a balance rather than leave it with an operator.
A block that includes your transaction. Casinos usually credit a deposit after a set number of confirmations, which is why a transaction can be visible on-chain and not yet in your balance.
A fixed payment to an affiliate for each player who registers and deposits. Simple to reconcile, and it stops paying once the player is delivered.
A round where a multiplier rises from 1x and can stop at any moment. You win if you cash out first. The chance of reaching a multiplier x is approximately one minus the house edge, divided by x.
The most common licence among crypto casinos. Curaçao replaced its old master-licence system with direct licences from the Curaçao Gaming Authority, which is a real improvement, though it still carries no weight with a US, UK or French regulator.
An arrangement where someone else holds your keys, as a casino balance does. Convenient, and dependent entirely on that company remaining solvent and cooperative.
An operator-side cap on what you can pay in over a day, week or month. Increases usually take effect after a cooling-off period; decreases take effect immediately.
An identifier XRP deposits require so the exchange or casino knows which account the funds belong to. Sending without one does not destroy the funds but does turn the deposit into a support ticket.
The two-token structure underpinning sweepstakes casinos, and the specific feature that state legislation targeted in 2025 and 2026.
Affiliate revenue divided by clicks sent. A comparison site's core commercial metric, and one that rewards sending the right people rather than the most people.
Staking the same amount every round. It does not beat the house edge either, but it makes a bankroll last longer and keeps losses legible.
Spins credited at a fixed stake, usually the minimum. Their value is spins multiplied by spin value multiplied by RTP, before wagering: 200 spins at $0.10 is $20 of turnover, not $200 of value.
The percentage of a bet that counts toward a wagering requirement. Slots usually count 100%; blackjack and roulette often count 10% or less, which multiplies the real betting needed and your exposure to the house edge.
The Ethereum term for a network fee. Paid in ETH even when you are moving an ERC-20 token, which catches people out when their wallet holds only stablecoins.
Blocking access based on the visitor's location, which operators use to enforce their restricted-jurisdiction lists. Circumventing it with a VPN breaches the terms and typically ends in a confiscated balance rather than a clever workaround.
Total stakes minus total winnings paid. The operator's revenue before costs, and the figure most gambling taxes are calculated on.
The play-only currency in a sweepstakes casino. It has no redemption value, which is the point.
How often a game returns any win at all, regardless of size. A slot can have a 25% hit frequency and still be losing money steadily, because most hits pay less than the stake.
The keyed hash function most provably-fair systems use to combine the server seed, client seed and nonce into a result. Deterministic, so anyone with the three inputs can recompute the round.
A wallet connected to the internet. Convenient for deposits, and the appropriate place for only as much as you intend to play with.
The operator's mathematical margin, equal to 100% minus the RTP. It is not a risk the operator takes; it is the price of the entertainment, charged on every unit you wager.
A large fixed or pooled prize. Jackpot contributions are taken out of the base game's return, so a jackpot slot's everyday RTP is lower than it looks.
Identity verification: usually a government ID, sometimes a selfie, proof of address, and for larger accounts proof of where the money came from. Required by anti-money-laundering rules, and most often enforced at the moment you try to withdraw.
A real table filmed in a studio and streamed, with bets placed through the interface. The house edge is set by the rules of the game, exactly as in an RNG version.
A cap on what you are prepared to lose in a session or a period, set before you start. A limit decided while losing is not a limit.
Doubling your stake after every loss so that one win recovers everything. It converts many small wins into one catastrophic loss and does not change expected value. Table limits and your own bankroll both arrive long before the win does.
A clause capping the stake you may place while a bonus is active, commonly around $5. Exceeding it, even once and even by accident, is the most frequent reason a withdrawal is voided.
A cap on what you can withdraw from bonus winnings, regardless of how much you won. It limits your upside while leaving your downside untouched, which is what makes most no-deposit offers worth far less than they look.
The largest payout a game can produce, expressed as a multiple of the stake. A high cap is a marketing figure: reaching it is usually rarer than one in tens of thousands of rounds.
A slot mechanic licensed from Big Time Gaming where the number of symbols per reel changes each spin, producing up to 117,649 ways to win. More ways to win does not mean a higher RTP.
The equivalent of a destination tag on chains such as TON and EOS. Same purpose, same consequence when it is omitted.
A European regulator with substantive player-protection requirements and a complaints process that can compel an operator.
A clause rolling an affiliate's negative balance into the next month, so one large player win can wipe out several months of commission. Programmes without it are meaningfully better for the affiliate, and it is the clause most often buried.
The cost of moving crypto, paid to the network rather than to the casino. It varies with congestion and is the reason a small withdrawal can be uneconomic.
Gross gaming revenue after bonuses, payment costs and gaming taxes. Most affiliate revenue-share deals are calculated on NGR, which is why the deductions in a contract matter as much as the percentage.
A small credit or set of spins given without a deposit. Almost always capped by a low maximum cashout and high wagering, so its real value is a free look at the software rather than a route to a withdrawal.
You hold the keys. Nobody can freeze the funds, and nobody can recover them for you either.
A counter that increments with each bet, making every round unique even when the seed pair does not change.
A third-party service such as MoonPay or Banxa that converts a card payment into crypto. At most crypto casinos a card deposit is really an on-ramp purchase, with its own fees, limits and identity checks.
Another name for a wagering requirement. Used interchangeably, occasionally to make the same number sound smaller.
A prize that grows with every bet placed across a network until someone wins it. The advertised RTP of such a game includes the jackpot, which almost nobody will ever receive.
A cryptographic scheme that lets you verify a round was decided before you bet and not altered afterwards. It proves the result was not manipulated. It does not change the house edge, which remains exactly as published.
A share of the house edge on your wagers, returned regardless of whether you won or lost. Because it is paid on turnover rather than on outcome, it is the most predictable ongoing value an operator offers, and the reason high-volume players prefer it to a one-off match.
A periodic on-screen reminder of how long you have been playing and what you have staked. Mandatory in several regulated markets and worth switching on where it is optional.
A deposit match offered to existing players rather than new ones. Usually smaller than a welcome offer and carrying the same wagering mechanics.
The set of tools and practices that keep gambling a purchase rather than a problem: limits, self-exclusion, reality checks, and knowing the warning signs.
The software that produces outcomes in a non-live game. In regulated markets it is tested by an independent laboratory; in a provably-fair game you can test individual rounds yourself.
The percentage of total wagers a game is designed to pay back over millions of rounds. A 96% RTP means the game keeps 4% of everything staked, which is the house edge. It applies to turnover rather than to your deposit, so replaying the same money charges the edge again each time.
A symbol that pays or triggers a feature wherever it lands, without needing to be on a payline. Usually the symbol that starts free spins.
A binding request to be barred from gambling for a set period. National registers cover every licensed operator at once: GamStop in Great Britain and the interdiction volontaire de jeux run by the ANJ in France. Offshore operators sit outside those registers, which is one of the real costs of playing on them.
A random string the casino generates and commits to by publishing its hash before you play. Revealed after the seed is retired so you can confirm it matches the hash you were shown.
Evidence of where your money came from: payslips, bank statements, a record of a crypto purchase. Requested for large or unusual activity, and the verification step that takes longest to satisfy.
A token designed to hold a fixed value, usually one US dollar. Using one removes the volatility window between requesting a withdrawal and it confirming.
The redeemable currency in a sweepstakes casino, given away rather than sold, and exchangeable for prizes once wagered.
A US model using two virtual currencies to avoid being a real-money casino. Eleven states passed statutory bans in 2025 and 2026, and several operators withdrew from those markets.
Blackjack, roulette, baccarat, craps and their variants, played against the house rather than other players. Their house edges are the lowest and the best documented in a casino.
The British regulator, among the strictest in the world. Its rules cover advertising, affiliate conduct, affordability checks and mandatory participation in GamStop.
The statistical spread of results around the average. Variance is why a session almost never resembles the RTP: over a few hundred rounds the noise is far larger than the edge.
A tiered loyalty scheme that converts wagering volume into rakeback, reloads, level-up bonuses and sometimes a personal host. The tiers are funded by the same house edge that produced the volume.
How a game distributes its return. High volatility pays rarely and large, low volatility pays often and small. Two games with identical RTP can feel completely different, and the high-volatility one will empty a small bankroll faster despite paying the same on average.
The total amount you must bet before bonus funds can be withdrawn, expressed as a multiple. The multiple matters less than what it applies to: 40x on a $100 bonus is $4,000 of betting, while 40x on deposit plus bonus is $8,000.
A symbol that substitutes for others to complete a winning combination. Variants include expanding, sticky and multiplier wilds.
