What Does “Over 25” Mean in Tennis Betting?
In Over 25 tennis betting, you’re betting that the total number of games played in a match will be more than 25.
- If 26 or more games are played in total → Bet wins.
- If 25 or fewer games are played → Bet loses.
How Are Total Games Counted?
Total games = All games in all sets, regardless of the winner.
For example, in a 3-set match:
- Set 1: 6–4 → 10 games
- Set 2: 7–6 → 13 games
- Set 3: 6–3 → 9 games
Total = 10 + 13 + 9 = 32 games
Over 25 = WIN
Key Rules to Remember:
- Applies to full match (usually best of 3 sets).
- Tiebreak games count as 1 game (e.g. 7–6 = 13 games total).
- If a player retires early, the bet is usually void (depends on bookmaker).
Examples Scenarios:
Example 1 – Bet Wins:
- Final Score: 7–6, 6–7, 6–4
- Games: 13 + 13 + 10 = 36 games
- Over 25 WINS
Example 2 – Bet Loses:
- Final Score: 6–3, 6–4
- Games: 9 + 10 = 19 games
- ➖ Over 25 LOSES
Example 3 – Close One:
- Final Score: 6–4, 7–6, 4–6
- Games: 10 + 13 + 10 = 33 games
- Over 25 WINS
When to Consider Betting Over 25
Good situations:
- Two players with strong serves and similar skill.
- Head-to-head history shows close matches.
- Grand Slam matches (men’s best of 5 sets — more chances for higher game totals).
Avoid Betting Over 25 If:
- One player is much stronger (likely straight-sets win).
- Clay court matches with long rallies but low game totals.
- Players frequently win or lose in short matches.
Betting Tip:
Look for matchups like:
- Isner vs. Anderson
- Medvedev vs. Zverev
These often go to tiebreaks and long matches.
