Bonus Bets must be used in whole as they cannot be split into multiple wagers. When you win a bet for which you have used a Bonus Bet, only the prize amount of that bet will be returned to your wallet. Any Bonus Bet values used are not included in settlement returns.
The Bonus Bet must be used in full. How are Bonus Bets paid out? When you place a bet using a Bonus Bet the winnings are calculated differently to a cash bet. A bet placed with a Bonus Bet will pay out the winnings minus the Bonus Bet stake.
