Casino bonus glossary

Every bonus term that decides what an offer is worth, defined in one line — and linked to the guide that shows the arithmetic.

In short

A casino bonus glossary defines the terms that decide what a bonus is really worth: the wagering requirement (how many times you must bet it), the maximum bet and time limit that can void it, game weighting, and the difference between a sticky and a non-sticky bonus. Each term below is linked to a full explanation.

These are the words in the terms and conditions that decide whether a bonus is worth claiming. Each definition is deliberately short; where a term needs the arithmetic, it links to the guide that works it out.

Wagering requirement
The number of times you must bet a bonus, and often your deposit too, before winnings can be withdrawn. A 35× requirement on a 500 € bonus means 17,500 € in bets. Read the guide →
Rollover
Another word for the wagering requirement: the total turnover you have to stake before a bonus becomes real, withdrawable money. Read the guide →
Turnover to clear
The actual amount you must bet to release a bonus — the wagering multiplier times the amount it applies to. Our calculator works it out for any offer. Read the guide →
Maximum bet rule
A cap on how much you can stake per spin or hand while a bonus is active, commonly 5 €. Going over it can void the bonus and every win attached to it. Read the guide →
Game weighting
The share each game type contributes to wagering. Slots usually count 100%, table games far less, so 1 € bet on roulette may clear only a few cents of the requirement. Read the guide →
Free spins
Bonus spins on set slots at a fixed stake. Winnings are usually paid as bonus funds that carry their own, separate wagering requirement. Read the guide →
No-deposit bonus
A bonus credited without any deposit. None of the eight operators here offer one — every welcome bonus on this site requires a deposit. Read the guide →
Sticky bonus
A bonus that cannot itself be withdrawn, only the winnings made with it. When you cash out, the bonus amount is removed from your balance. Read the guide →
Non-sticky bonus
A bonus kept separate from your own money, so you play your cash first and can withdraw it without forfeiting the bonus or its terms. Read the guide →
Deposit match
A bonus that mirrors your deposit by a set percentage. A 100% match doubles your money, up to a cap — 500 € across these operators. Read the guide →
Welcome bonus
The first-deposit offer for new players. Across the operators on this site it is 100% up to 500 € plus 200 free spins. Read the guide →
Reload bonus
A deposit bonus for existing players on later deposits, usually smaller than the welcome offer and run as a recurring promotion.
Cashback
A refund of a percentage of net losses over a set period, sometimes with lighter wagering than a match bonus, or none at all.
RTP (return to player)
The long-run percentage a slot pays back. A 96% RTP returns 96 € for every 100 € staked on average, measured over millions of spins. Read the guide →
House edge
The casino's built-in margin: 100% minus the RTP. A 96% RTP is a 4% house edge — the share the operator keeps over time. Read the guide →
Volatility
How a slot pays out. High-volatility games pay rarely but large; low-volatility games pay often but small. It affects how safely you can clear wagering. Read the guide →
Crypto bonus
A separate welcome bonus for cryptocurrency deposits — here 200% up to 3,000 USDT — carrying its own, larger wagering requirement. Read the guide →
Bonus Crab
A gamified extra at some operators: one pick from a prize grid — free spins, bonus cash or a free bet — on top of the standard welcome package. Read the guide →
Sportsbook bonus
A separate welcome offer for sports betting, with its own minimum odds and rollover. Caps here are 100 € or 200 €, depending on the operator. Read the guide →
Free bet
A staked bet where you keep any winnings but not the stake itself. It is the usual form a sportsbook welcome bonus takes. Read the guide →
Maximum cashout
A cap on how much you can withdraw from a bonus, no matter how much you win with it. Winnings above the cap are forfeited.
Time limit
The window to meet the wagering requirement before the bonus and its winnings expire — 10 days across the operators on this site. Read the guide →
KYC verification
The identity check — know your customer — required before your first withdrawal: photo ID and proof of address. Complete it early to avoid delays. Read the guide →
Opt-in
Actively choosing a bonus — ticking a box or entering a code — so it applies to your deposit. These operators need no code, but you still opt in.
Excluded payment methods
Deposit methods that disqualify a bonus. Skrill and Neteller are excluded across these operators; card, bank transfer and crypto qualify. Read the guide →
Minimum deposit
The smallest deposit that qualifies for a bonus — 20 € across the operators on this site. Read the guide →
