Your bet options are over; under

Predict whether the total games by both players in the specified set be more than or less than the specified number.

In the event of retirement, disqualification or change of surface mid-match, bets will be void unless there is no conceivable way the set and/or match could be played to its natural conclusion without unconditionally determining the result of that market.

Example 1: A set is abandoned at 4-4: bets on Over/Under 9.5 games or fewer in the set are settled as winners/losers respectively, since any natural conclusion to the set would have at least 10 games; bets on Over/Under 10.5 games or more are void.

Example 2:  A best-of-3 sets match is abandoned at 6-4 2-6: bets on Over/Under 23.5 games or fewer in match will be settled as winners/losers respectively, since any natural conclusion to the match would have at least 24 games; bets on Over/Under 24.5 games or more are void.

Example 3: A best-of-3 sets match is abandoned at 6-4 4-6 5-5: bets on either player with a handicap of +2.5 or more will be settled as winners, bets on either player with a handicap of -2.5 or less will be settled as losers, and bets on the tie with a handicap of +/- 3 or more will be settled as losers. All bets on handicaps ranging from -2 to +2 will be void.
