Over 23.5 in Tennis Sports Betting refers to a total games bet where you’re betting that the total number of games played in the match will be more than 23.5.
What Does “Over 23.5 Games” Mean?
In this bet, you’re predicting that both players combined will play at least 24 games.
- You win the bet if the match has 24 or more games.
- You lose the bet if the match ends in 23 or fewer games.
Note: The “.5” ensures that the result can’t land exactly on the line. It avoids a “push” (refund).
How Are Games Counted in Tennis?
- A set must be won by at least 6 games (e.g. 6-4).
- If tied at 6-6, there’s a tiebreak (which counts as 1 game).
- So, a set can have a minimum of 6 games and up to 13 games (7-6).

Betting Tips for Over 23.5 Games
- Look for evenly matched players:
- Matches between two strong servers (like Isner, Opelka, Hurkacz) tend to go longer.
- Avoid lopsided matchups:
- If one player is dominant, it could be a quick 6-2, 6-1 type result.
- Check Head-to-Head stats:
- Have their past matches often gone 3 sets or had tie-breaks?
- Consider surface type:
- Grass favors servers, increasing chances of longer sets.
- Clay can also stretch games, but depends on the players.
- Watch for tournament format:
- Best-of-3 or Best-of-5?
- Over 23.5 is more common in best-of-3 matches.
Best Situations to Bet Over 23.5
- ATP matches with two players ranked in the top 50
- Finals or semifinals of tournaments where players are closely matched
