What Does Over (21.5) Games – Player 1 Mean?
When you place this bet, you are predicting that Player 1 will win at least 22 games in the match.
- Over 21.5 = Winning bet if Player 1 wins 22 games or more
- Under 21.5 = Winning bet if Player 1 wins 21 games or fewer
This market is common in ATP, WTA, and Grand Slam matches.
How Is the Bet Calculated?
Only the games won by Player 1 are counted.
It does not depend on who wins the match.
Example of games count:
- Set 1: 6–4 → Player 1 wins 6 games
- Set 2: 7–6 → Player 1 wins 7 games
- Set 3: 6–3 → Player 1 wins 6 games
Total games won by Player 1 = 6 + 7 + 6 = 19 games
Under 21.5 loses | Over 21.5 loses
