Besides your main cash balance that showcases how much real cash you have available for wagering or withdrawing, your casino account will have a separate balance that displays the bonus cash amount you have at your disposal. A separate bonus balance is needed because the bonus funds and associated winnings are typically non-withdrawable until certain requirements are met. When you make bets in a casino game using the money you deposited, your winnings go to your main cash balance. On the other hand, when you use your bonus money for wagering, the resulting winnings are credited to your bonus balance.
