Bets are settled on the results provided by the organising federation. If the match doesn't take place, all bets on it are void.
Only 2-Way match betting includes overtime and any shootout. All other markets are settled at the end of regular time (60 minutes).
If a match is suspended, all markets are void unless the outcome has been unequivocally decided.
