Tennis

1. Match Winner
If a tennis match ends with abandonment or the disqualification of a player, all bets on the winner of that match will be voided.
All other bets are valid when the result is clearly established, i.e. there is no other possible result even before a player's possible withdrawal. Bets that have not been established at the time of withdrawal are void.
For betting purposes, the winner is always the player who is declared the winner by the match umpire and officially advances to the next round or is declared as winner of the tournament. The same applies to “Doubles” matches. 

2. Set Betting
The full number of sets required to win the match must be completed. If a player is awarded the match prior to the full number of sets being completed, all correct set betting on that match will be void.

3. Current Set Winner (Live)
If a player retires from a match whilst a set is in progress but before the set has been completed, the set shall be deemed incomplete and stakes shall be returned.

4. Game by Game Betting (Live)
There are eight possible results for a game:
• Server wins to love
• Server wins to 15
• Server wins to 30
• Server wins to deuce
• Receiver wins to love
• Receiver wins to 15
• Receiver wins to 30
• Receiver wins to deuce
If a game is completed after an interruption for any reason, that game shall be deemed to be complete for betting purposes.
If a game is completed by the awarding of a penalty point by the umpire, the game shall be deemed complete. However if a game is completed by the awarding of a penalty game by the umpire, the game shall be void and all stakes shall be returned.
If a player retires from a match while a game is in progress but before that game has been completed, that game shall be deemed incomplete and all stakes shall be returned.
Bets on a game which subsequently becomes a tie break will be settled as void.

5. Total Games 
Bets on the total number of games in a match will be over/under a particular number, e.g. 21.5 games.
In the event of a retirement, bets will be void unless at the time of the withdrawal the result of the total games is already determined e.g. If a match is abandoned at 6-4 4-4, bets on Over/Under 19.5 games or fewer in the match are settled as winners/losers respectively, since any conclusion to the match would have to have had at least 20 games.

6. Handicap Betting 
The bet is based on the number of games each player wins in a given match, e.g. a player given a +2.5 game handicap who loses a match 7-6 7-6, would be the winner for handicap betting purposes.
In the event of a retirement, the same logic which shall apply to the total games in a set or match applies to handicap bets. For example, a player retires at 6-4 4-6 4-4; handicap bets of +/- 2.5 games would be settled as won/lost since neither player can win by more than 2 games. Bets on +/- 1.5 games would be void as the result is not determined. 

7. Retirements 
Matches which cannot be played to their natural conclusion without unconditionally affecting the outcome of a bet will be settled in the event of a retirement (excluding Match Winner). 
All bets that have been settled or are determined (i.e. the outcome is already decided) at the time a player retires are valid and will be settled accordingly (including cashed out bets). All bets that are not decided at the time a player retires shall be void.
Disqualifications are subject to the same settlement rules as retirements.

8. Set/Game/Tie-Break
A set/game/tie-break is deemed to have taken place as soon as its first ball has been played but the outcome of the set/game/tie-break is not decided before the set/game/tie-break is completed. If one point in a tie-break is played prior to a retirement/withdrawal, ‘Will there be a tie break in the match’ would be settled as ‘Yes’.

9. Tie-Break
A tie-break is counted as one game for betting purposes. A set which finishes 7-6 is deemed to include 13 games, rather than 12 games + a tie-break.
If a match is decided by a "Match Tie-Break" instead of a final set, then the Match Tie-Break will count as a set for betting purposes. 
For tennis matches that use the Match Tie-Break (in place of a final set), in the event that the next game turns out to be a Match Tie-Break, bets on the following markets will all be settled as void:
·         Next Game Winner
·         Next Game Score Betting
·         Next Game Points
·         Next Game to go to Deuce
If the next game is a regular game (i.e. not a Match Tie-Break) then bets will be settled as usual

10. To Win/Lose 1st Set and Win the Match 
If either player withdraws from the match before the first set finishes, bets will be void. If the first set has been completed, the match part of the bet will be determined by the player awarded the match and bets will be settled.

11. Interrupted Matches 
If a match is interrupted or postponed, the bets within the framework of the tournament will remain valid until the match is completed. An interruption or overnight suspension of a match is not grounds for a bet to be void.

12. Continued Matches (After a suspension of play) 
In the case of interruptions, the continuation of the match can be offered, including the result at the time of the interruption. This continuation will be deemed a new match for betting purposes. In the case that a match is interrupted and not resumed, all bets on the continuation (including the result at the time of the interruption) of the match will be void.

13. Who will win/play more games in round X 
The winner of a bet is the player who wins/plays the most games after comparing two players in the same round of a tournament. It is not important whether one of the two players wins or loses his/her match. For the purposes of this bet, only the games won/played by each player will be counted (a tie-break is counted as a game).

14. Team competitions (Davis Cup, Fed Cup, Hopman Cup, Laver Cup) 
All bets on the winner of the team competition are valid as soon as the first ball of the first match is played. In the event of the retirement of one of the teams, the winner of the bet will be the team officially declared the winner by the respective governing body
Should a team withdraw before the first ball of the first match of the team competition has been played, all bets will be void.

15. Outright Betting/Quarter Betting/Half Betting
Bets are settled as all in-play or not. If a player enters a tournament and subsequently withdraws, prior to or during the tournament, all bets will stand. 

16. Winning Quarter/Winning Half
The tournament must be completed for bets to stand.

17. To Reach the Final
All-in, run or not (see outright betting). 

18. Cash Out
All bets where ‘cash out’ has been accepted prior to a retirement will remain settled. 
‘Cash Out’ is not guaranteed to be available for the entirety of a match (see specific cash out rules below). 

Aside from the following special betting rules, the common betting rules apply. The special rules will take precedence over the general rules nevertheless.
