See here for the Sports Rules that apply for bets placed before: 12-01-2023
A match will be deemed to have begun once the first serve has been struck.
If any of the named players in a match change before the match starts, then all bets on that match will be void.
If a match is abandoned, postponed or cancelled, all bets will be void unless the event is completed at the same venue within 24 hours of the original start time.
If a player or team is withdrawn prior to the start of an event, all bets will be void. We may apply the equivalent of a Tattersalls Rule 4(c) deduction to any winnings from bets on the event’s remaining participants (based on the odds of the participant that is withdrawn).
If a player is given a walkover, bets on that match will be void.
In the event of a disqualification or retirement from a match or an abandonment of a match, all bets on the correct score of that match will be void.
If during a match, there is a change to the total number of sets to be played, all bets on the Correct Score of that match will be void (but all other markets involving the relevant match will stand).
The number first appearing in the score is the score of the home player, and the number appearing second is the score of the away player.
Following either a disqualification or retirement from a match or an abandonment of a match, all bets on these markets will be void other than those markets that have already been unconditionally determined.
The Sportsbook General Rules will apply for any category of bets or markets not referred to in these Specific Sports Rules.
