Many users have this question, but it’s quite simple to understand. If it’s a bonus that comes from a deposit, the first credits used for bets will be from your real wallet. Once these real credits are depleted, the system will start deducting from the bonus wallet for betting.
However, in the case of Free Bets (bets that don’t require a deposit to be placed), only the bonus wallet will be used.
