When a tennis match goes to a tiebreaker, individual tiebreaker points will NOT be counted towards the grading of over/under totals.
In other words, the tiebreaker adds one game only to the total.
For example, if a set is tied 6-6, a tiebreaker will be played to determine who wins the set. If that tiebreaker ends with a score of 7-5, the set's final score is 7-6 and in this case, 13 games count towards the total.
- A Regular Tie Breaker is 1st player to 7 points with a 2 point advantage.
- A Super Tie Breaker is 1st player to 10 Points with a 2 Point advantage.
For Doubles, Exhibitions and some Regular tour events, a Super Tiebreaker rule is applied when a match goes to the third set. This means there is no traditional third set played, but instead, a tiebreaker (usually to 10 points) is used.
The same as a regular tiebreaker, when this happens only one game is added to the total for betting purposes.
Super Tie Breaker example
| 1st Set | 2nd Set | Super Tiebreaker | |
| Player A | 6 | 2 | 10(0) |
| Player B | 1 | 6 | 12(1) |
In this example, Player B wins the match, 2 Sets to 1, with the final game totals tied at 8.
- Player A game total: 6 + 2 + 0 = 8
- Player B game total: 1 + 6 + 1 = 8
Beginning in 2019, the four Grand Slams each have different ways of winning a final set:
- Wimbledon: Final set. First to 7 points, tiebreak at 12-12
- Australian Open: Final set. First to 10 points, tiebreak at 6-6
- US Open: Final set. First to 7 points, tiebreak at 6-6
- French Open: Final set. Advantage set, with no tiebreak
