What is a casino welcome bonus?
A casino welcome bonus is an offer for new players. A deposit match adds bonus funds in proportion to a qualifying deposit; free spins award plays on specified slots; a no-deposit offer can be claimed without first funding the account. These rewards have different release and withdrawal rules, so registration alone does not make every welcome offer available.
The comparison above covers first-deposit offers. A headline for a whole welcome package can combine several deposits, each with its own percentage, cap and minimum. For example, RioAce’s five-stage package cannot be claimed through one deposit. Use the first-stage terms when comparing what your initial deposit receives.
How the deposit match and cap work
For an ordinary cash match, the calculation is qualifying deposit × match percentage, limited by the bonus cap. In an illustrative offer with a 100% match capped at €30, a €20 deposit earns €20 in bonus funds, while a €50 deposit earns €30. The cap limits the award; it does not describe how much you may withdraw later.
Set your deposit budget before comparing offers. A bigger deposit made only to reach the cap also puts more of your money at risk. A 200% deposit match adds twice the deposit as bonus funds below its cap, but its wagering rules determine how much play the award requires.
Read wagering before the headline amount
Wagering is the total in qualifying stakes needed to clear an award. The base matters as much as the multiplier. In two illustrative offers using a €25 deposit and €25 bonus, 40× the bonus requires €1,000 in qualifying stakes; 40× the deposit and bonus requires €2,000.
Game contribution then determines how much of each stake counts. At an illustrative 50% contribution, €2 in bets adds €1 to the target. A game can be available in the lobby yet excluded from bonus play or contribute nothing. Turnover is neither a new deposit requirement nor a prediction of losses: your balance can run out before you complete it.
LollySpins’ bonus section explains its cash match and spins separately. Windetta’s welcome section helps you distinguish the Shark cash-match path from its other offers. Those are useful next reads if you want to compare the mechanics behind similar headline percentages.

Why BC.GAME works differently
BC.GAME’s partner offer combines a 180% locked USD bonus, capped at $1,000 from a $5 first deposit, with separate 40% rakeback. The locked match is released through amount wagered × house edge × 1%. The rakeback uses amount wagered × house edge × 40% and is immediately available to play or withdraw without additional wagering. Adding the two percentages does not produce a 220% cash match.
At an illustrative 4% house edge, $1,000 in stakes releases $0.40 from the locked bonus and credits $16 in separate rakeback. This shows why its match percentage cannot be compared directly with a conventional bonus credited for play.
The partner terms have no expiry, maximum bet, game restriction or cashout cap. The $1,000 limit applies to the match; rakeback is uncapped. Withdrawing forfeits the remaining bonus. Open the account’s Bonus section before accepting to see the conditions attached to your award.
Before you accept a welcome bonus
Check these details against the offer shown in your account:
- Eligibility and activation: your location, new-player status, payment method and any opt-in or code. Select or decline the bonus before confirming the deposit; an automatically applied award may need support to remove it.
- Bet size and time: the maximum permitted stake and the deadline for completing wagering. A separate claim window tells you when to activate an award, not how long you have to clear it. An unknown maximum bet is not permission to choose any stake.
- Free spins: the named game, stake per spin, delivery batches, activation windows and rules for the resulting winnings. A spin count does not show its cash value or conversion cap.
- Withdrawal: the amount eligible for conversion, any continuing cashout ceiling, verification requirements and the payment method. Completing wagering can still leave a cap on bonus-derived funds; requesting a withdrawal can cancel an active bonus or unused spins.
The full reviews link these conditions to each casino’s cashier and withdrawal rules. For an adjustable turnover example, open the Snatch bonus calculator. Use your actual award and game contribution, and keep your spending limit separate from the target shown.
