A voided bet is where your selection may have been scratched, cancelled, abandoned, injured prior to the event etc. Essentially, when a bet is voided Sportsbet will refund the stake unless it is in a multi or Same Game Multi.
Single Bets – Stake refunded back to your account.
Multi Bets – Voided leg will be removed from the multi, and the odds will be recalculated on the remaining legs.
Same Game Multi/Same Race Multi – If one or more of your legs in a Same Game/Race Multi have been voided, then your entire Same Game/Race Multi will become void and your stake will be returned. However, if the Same Game/Race Multi is a leg in a standard multi bet, then the multi stands and is settled on the remaining legs, excluding the odds of the voided Same Game/Race Multi.
