If a match starts but is later abandoned, all undetermined bets will be voided as long as the match is not played to a finish before midnight local time on its scheduled date.
However, if a match is postponed, bets on that match will be void unless it kicks-off before midnight local-time on the same day. Games which have their kick-off altered well in advance to accommodate live TV, or to ease fixture congestion will not constitute a postponement.
For major tournaments (such as the World Cup), if a game is delayed beyond midnight local time, all bets will stand and be settled once the game is played, as long as the game is played to a finish within 72 hours.
