Before betting on a bookmaker site, it is advantageous to know the rules for tennis bets of each bookmaker site.

Bets on the winner

In tennis, the most common bets are placed on the winner of the game. Among the bookmaker, there are two rules for this type of betting:

- The bet on the winner: from the point the game starts (Betclic, Bwin or Interwetten)
- The bet on the winner: from the point a set is played (Sportingbet and Unibet)

Finally Betclic specify that the bet is valid on the winner from the point the game starts and must therefore be understood as live bet.

Bets on the number of sets, the number of games and points

All online betting sites have the same rule. The subject of the bet must be completed that the bet becomes valid. For example, if you predict that a set has 9 games, the set needs to be already completed that your bet becomes valid. If you bet on the number of sets in a game and a player gives up during the game, your bet will be cancelled and you get your money back.

Sportingbet explains its rule for the winner of a point like this: The bet on the winner of a point will be cancelled if the point is not played, or if the point is awarded on the basis of a penalty. On the other hand, the bet to win the game and the number of points stays adhere, even if the game thanks to one or more penalty points has been won.

Bets on a displaced Game

On all online bookmaker sites, the bets stays adhere if the date of the game, the place or the soil is changed. The bets on the games take place on several days stays adhere. This rule is especially important to Wimbledon and the U.S. Open. These tournaments are often tournaments held on various days and on different soil … for reasons of rain or darkness.
