Cash balance first, then bonus funds!
There are mainly two types of casino bonuses – sticky bonus and non sticky bonus.
Upon claiming a sticky bonus, your deposit instantly becomes tied to the bonus funds given to you by the casino as part of a bonus offer, meaning you cannot request a withdrawal of your winnings until wagering has been completed.
The non sticky bonus, on the other hand, allows you to play with your own cash balance first, free of any wagering requirements or bonus terms. The bonus only activates once you dip into the bonus balance.
