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
A deposit bonus adds a percentage of your first deposit. For example, a €20 deposit with a 200% bonus adds €40, giving a €60 playing balance, subject to the offer terms.
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.
