The maximum Win Bonus available is up to 650% of net winnings.
The Win Bonus is calculated on net winnings only (excluding stake).
The Win Bonus is applied automatically to qualifying bets upon settlement. If no bonus is displayed on the betslip, the bet does not qualify.
Boosted winnings are credited to the player’s account as cash.
Single bets, outright bets, and tournament bets are not eligible for the Win Bonus.
Bets placed on markets that may result in a stake refund or partial win (e.g. Draw No Bet) are not eligible.
Void, cancelled, or refunded selections are not counted as qualifying selections.
If selections are voided or cancelled, the remaining selections must still meet the minimum odds and selection requirements to qualify. The final bonus applied may differ from the original betslip.
If the number of qualifying selections falls below the required minimum after settlement, the Win Boost will not be applied.
Cash-out bets (full or partial) will result in forfeiture of the Win Bonus.
