Tennis betting markets explained: match winner, sets, games and tie-breaks
Tennis is one of the easiest sports to start with: two players, no draw, and a clear scoring system. This guide explains the main tennis markets in plain language, shows how each one is settled with worked numbers, and explains why tennis is the classic sport for two-way sure bets, plus the one rule you must check first.

Tennis scoring in one minute
A tennis match is made of sets, and each set is made of games. A player wins a set by winning six games with a lead of at least two. At 6-6 most sets are decided by a tie-break, a short game to seven points (lead of two needed). Most tournaments are played as best of three sets; men's Grand Slams are best of five. The rules of each event, set by the ITF and the tours, decide details such as the final-set tie-break.
Every tennis market is a question about one of these units: who wins the match, how the sets end, how many games are played, or whether there is a tie-break.
Match winner
The main market. You pick the player who wins the match. There are only two outcomes, because a tennis match cannot end in a draw. Example: Player A at 1.50, Player B at 2.60. A €20 bet on Player A returns €30 (net +€10) if A wins.
The odds also show the bookmaker's view and margin: 1/1.50 + 1/2.60 = 0.667 + 0.385 = 1.051, so this bookmaker builds in a margin of about 5%. Our guide to implied probability explains this step by step.
Set betting
You bet on the exact score in sets. In a best-of-three match there are four possible results: 2-0, 2-1, 1-2 and 0-2. In best of five there are six (3-0, 3-1, 3-2 and the reverse). Because you need the exact score, the odds are higher: a favourite at 1.50 to win might be around 2.20 to win 2-0.
Related markets: total sets (over/under 2.5 sets in best of three, which is the same as "will the match go to a third set") and set handicap (Player A −1.5 sets means A must win 2-0).
Game handicaps and total games
These markets count games across the whole match, which makes them the tennis equivalent of handicaps and totals in other sports.
- Game handicap. Player A −3.5 games means A must win at least four more games than B. In a 6-4, 6-3 win, A wins 12 games and B wins 7: a difference of 5, so A −3.5 wins. In a 7-6, 4-6, 6-4 win, A wins 17 and B wins 16: difference 1, so A −3.5 loses even though A won the match. A tie-break counts as one game.
- Total games. Over/under 22.5 games. A 6-4, 6-3 match has 19 games (under). A 7-6, 4-6, 6-4 match has 33 games (over).
- Set markets. First set winner, first set total games, first set correct score. These are settled once the set is finished.
Handicap lines with .5 cannot end level. Whole-number lines (for example −3) are refunded when the difference is exactly 3, which works like the Asian handicap logic explained in our Asian handicap guide.
Tie-break markets
"Tie-break in the match: yes/no" asks whether at least one set reaches 6-6. "Tie-break in set 1: yes/no" asks the same for one set. Serve-dominant players on fast courts produce more tie-breaks; long rallies on clay produce fewer. Be careful with deciding sets that have special rules, for example a match tie-break (first to ten points) instead of a full third set in some doubles events. Read how the bookmaker counts it: usually as one game and one set.
Why tennis suits two-way sure bets
A sure bet means backing every possible outcome at different bookmakers so that, if the odds are high enough, every result returns more than the total stake. In football the main market has three outcomes (home, draw, away), so you need three good prices at once. In tennis you only need two.
Bookmaker A offers Player 1 at 1.85. Bookmaker B offers Player 2 at 2.25. Add the inverses: 1/1.85 + 1/2.25 = 0.5405 + 0.4444 = 0.9850. Because the sum is below 1, a sure bet exists, worth about 1.5% of the total stake.
| Leg | Odds | Stake | Return if it wins |
|---|---|---|---|
| Player 1 at A | 1.85 | €54.88 | €101.53 |
| Player 2 at B | 2.25 | €45.12 | €101.52 |
Total stake €100. Whoever wins, you get back about €101.52, a profit of roughly €1.52, as long as both bets stand and are settled the same way.
Tennis also has many matches every day, across tours, challengers and ITF events, so prices change often and differences between bookmakers appear regularly. See sure betting by sport for how tennis compares with football, hockey and basketball.
What can go wrong
The most important tennis rule is retirement. If a player retires injured, bookmakers settle differently: some void the bet, some pay the player who advances, some only settle if a set (or the first set) was completed. If your two legs follow different retirement rules, one can lose while the other is voided. Read our tennis retirement rules guide before your first tennis sure bet.
- Prices move fast, especially just before the start and during play. Place the leg with the more fragile price first.
- Lower-tier events have lower limits and are more often voided after integrity alerts. Smaller stakes are sensible there.
- Game and set markets can have different rules for retirements and match tie-breaks than the match winner. Check them separately.
Frequently asked questions
What is the most common tennis bet?
The match winner. You pick the player who wins the match. There are only two outcomes because tennis has no draw.
How does a game handicap work in tennis?
The handicap is added to or taken from a player's total games across the whole match. Player A −3.5 games wins only if A wins at least four more games than the opponent. A tie-break counts as one game.
Does a tie-break count as a game in total games markets?
Yes, at most bookmakers a set tie-break counts as one game. A match tie-break played instead of a final set is usually counted as one game and one set, but check the bookmaker's tennis rules.
Why is tennis popular for sure bets?
Because the main market has only two outcomes, you need good prices at just two bookmakers to cover every result. The key risk is that bookmakers settle retirements differently, so check that rule on both sides.
