In a multi-bet, all selections must win for the bet to be successful. If any of the selected teams or events lose, the entire bet is settled as a loss. In sports betting, a multi-bet (also known as an accumulator, parlay, or combo bet) is a type of bet that combines multiple individual bets into a single wager.
If a Multi bet loses due to a single event, the bettor will be eligible for a refund on their stake.
