How to choose the best bonus?
Don't be blinded by the headline amount. A 200% bonus with x60 wagering is often less attractive than a €40 bonus with x25 wagering. Here are the 3 criteria to look at:
1. Wagering requirement
Wagering indicates how many times you must bet the bonus before you can withdraw winnings. The lower, the better.
📊 Real example — Celsius (€40, x30)
Amount to wager:
On slots with 96% RTP, your expected loss on €1,200 is around €48. The bonus is slightly unfavourable mathematically, but variance can still make you win big.
2. Game contribution
Not all games count the same toward wagering:
- Slots: 100% (the fastest to complete)
- Blackjack / Roulette: 5–10% (very slow)
- Live Casino: 0% (often excluded)
- Mini-games (Plinko, Mines) : varies; check the terms
3. Time limit and max stake
- Time limit: 7 days is tight, 30 days is comfortable
- Max stake: if capped at €5/spin, avoid high-volatility slots
- Max withdrawal: some bonuses cap your winnings
For a beginner, RingoSpin (x25 wagering) is the most accessible. Celsius (€40, x30) is an excellent middle ground. Slott (200%) is ideal if you want the biggest bonus and have time to clear the wagering.
Bonus types explained
Welcome (match) bonus
Le casino double (ou plus) ton premier dépôt. C'est le bonus le plus courant. Ex : dépose 20€ sur Slott, reçois €40 bonus, joue avec 60€.
Free spins
Free rounds on a specific slot machine. Winnings are subject to wagering. Always check which slot and at what value (€0.10 or €0.20 per spin).
Cashback
The casino refunds a % of your net losses. The big advantage: often with no wagering. Celsius offers 5% cashback every Monday.
