Two clauses in bonus terms cause most of the disputes: how much each game counts towards wagering, and how large a bet you may place while a bonus is active. Both are easy to check and easy to forget.
Game contribution
When you wager a bonus, the casino counts only a percentage of each bet towards the requirement. The percentage depends on the game type. These are typical patterns, not rules — your casino’s terms decide.
| Game type | Common contribution | Effect on €1,000 of play |
|---|---|---|
| Slots | 100% | €1,000 counts |
| Roulette and blackjack | 0–20% | €0–€200 counts |
| Live casino | 0–10% | €0–€100 counts |
| Jackpot slots | Often 0% | Often excluded |
A 10% contribution turns a 35x requirement into an effective 350x on that game. In practice it means: wager with slots that count in full, and do not play roulette to clear a bonus.
Maximum bet while wagering
Most casinos cap the bet size during wagering — often a figure in the region of €5 per spin or per round. Placing a larger bet, even once, can be treated as a breach of terms and the casino may cancel the bonus and any winnings. The usual trap is switching to a higher stake after a good run.
How to protect yourself
- Screenshot the bonus terms on the day you claim, including the max bet and contribution table.
- Set your stake below the limit and leave it there.
- Check the excluded-games list; high-RTP and jackpot slots are frequent exclusions.
- Watch the “bonus balance” and “cash balance” split. Some casinos play cash first, some bonus first.
- If you decide not to continue, ask support how to forfeit the bonus so that you can withdraw your own deposit.
If a casino voids your win
Ask for the exact clause and the bet record that triggered it. A fair operator will point to the term and the round. If the explanation is vague, follow the steps in our complaint guide.
