Slot Weightings and Maximum Bet Limits
The terms also specify which games count and how much you can bet. Slots normally count 100% toward your wagering, but table games like blackjack might only count 10%. Also, these bonuses almost always come with a maximum bet limit per round, say €5. If you bet over that limit while the bonus is active, you can lose the bonus and any winnings you’ve made from it. That would undermine the whole point.
