1) 2-way bets: In a tennis match that ends with one of the players retiring, the “2-way” bet is declared valid as soon as the first ball of the match has been played. For betting purposes, the winner is always the player who is declared the winner by the match referee. The same applies to “Doubles” matches.
2) All other bets that are determined (i.e. the outcome is already decided) at the time a player retires are valid and will be settled accordingly. All bets that are not decided at the time a player retires are void.
3)A set/game/tie-break is deemed to have taken place as soon as the first ball of that set/game/tie-break has been played.
4) All bets referring to the winner or the end result of a set/game/tie-break are void if the respective set/game/tie-break has not been completed.
5) For all bets referring to the number of games played, a “Tie-break” is counted as one game.
6) Champion’s Tie-break (played up to 10 points): If a match is decided by a "Champion’s Tie-break" instead of the final set, then the "Champion’s Tie-break" counts as a set for betting purposes but not as a “Tie-break”.
7) If a match is interrupted or postponed, the bets within the framework of the tournament will remain valid until the match is completed. However, matches that are interrupted or postponed, but which do not take place within the framework of the tournament (e.g. exhibition matches), will be declared invalid if the match is not resumed and completed within 72 hours.
8) In 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 case a match is interrupted and not resumed, then all bets on the continuation (including the result at the time of the interruption) of the match are void.
9) Tournament bets: If not otherwise stated, for all bets referring to the final result of a tournament, the “play or pay” principle applies.
10) Head-to-Head Game bets: “Who will win more games?” The winner of a head-to-head bet is the player who wins 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 match. For the purposes of this bet, only the games won by each player will be counted (a tie-break is counted as a game). Head-to-Head game bets are only offered on “Singles” matches, and “Doubles” matches will not be used to evaluate the bet. The bet is always based on the corresponding tournament round (e.g. Round 1, Round 2, etc.) Should at least one of the two matches end with the retirement of any player, then all bets will be void.
11) Team competitions (Davis Cup, Fed Cup, Hopman Cup, World Team 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
12) Should a team withdraw before the first ball of the first match of the team competition has been played, then all bets will be void.
