Tennis Betting Rules: Retirements, Tie-Breaks, Walkovers and Surface Changes
Quick answer: if a player retires before the first set is finished, match winner bets are void. If the retirement comes after the first set, the player who goes through is settled as the winner. Markets already decided stand. A match tie-break played instead of a final set counts as one game in total games. A walkover is void. On a change of surface or venue, UK bookmakers disagree: some let bets stand, some void them.
Tennis is the sport where the same match most often settles differently from one bookmaker to the next. A player can stop after one game or after four hours, a match can be moved indoors, and a deciding set can be replaced by a ten-point tie-break that looks like eighteen games on the scoreboard but counts as one.
This guide compares the published tennis rules of two UK-licensed bookmakers, Sky Bet and Midnite, line by line, then works through retirements, total games and accumulators with numbers. It is about how bets are settled, not about who to back.
The next three weeks: ATP Finals and Davis Cup Final 8
Updated 9 November 2026. Two team-format and round robin events close the men's season. At the ATP Finals a retirement also changes the group table, which follows its own rule: how the ATP ranks players level on wins is in our ATP Finals round robin tiebreakers guide. Sky Bet's retirement rule names the Davis Cup explicitly.
| Event | Dates | Venue | Format |
|---|---|---|---|
| Nitto ATP Finals | Sun 15 to Sun 22 Nov 2026 (draw Thu 12 Nov) | Inalpi Arena, Turin | 8 singles players in two round robin groups of four, then semi-finals and final; best of three tie-break sets |
| Davis Cup Final 8 | Tue 24 to Sun 29 Nov 2026 | BolognaFiere, Bologna | 8 nations in a knockout: Italy, Spain, Germany, Great Britain, Austria, Korea, Czechia, Canada |
Two UK bookmakers, side by side
Both sets of rules were read on 9 November 2026. They agree on the big question, retirements, and part company on surface changes. Your own bookmaker's tennis rules have the final word, and they are usually one click from the help page.
| Situation | Sky Bet | Midnite |
|---|---|---|
| Retirement or disqualification before the first set is finished | Match odds void. All other markets void if not yet decided. | Match result void. |
| Retirement after the first set is finished | Match odds settled Win/Void (ATP, WTA, Grand Slams, Challengers, Davis Cup): the player deemed the winner is a winner. | Settled in favour of the player who progresses to the next round (UTR events excepted). |
| Markets already decided before the retirement | Stand. | Stand; 'Win first set and win match' type markets are void if a player withdraws before the first set ends. |
| Match (championship) tie-break in total games | Counts as 1 game. | Tie-break points are not counted in total games. |
| Number of sets changed (for example best of five moved to best of three) | Set betting void; match betting stands. | Not stated in the tennis rules. |
| Change of venue, surface, or indoor to outdoor | All bets stand, before or during the match. | All bets on the match void. |
| Rain or other delay mid-match | Bets stand. | Bets stand if the match is completed later or an official result is given. |
Retirements: the first set is the line
For years UK bookmakers split three ways on retirements: void whatever happens, void unless the match is completed, or settle once one set is played. The two rule sets read here both use the first set as the line. Midnite puts it in two sentences: "If the retirement happens during the first set the market will be voided" and "After the first set has concluded, the match will result in favour of the person who progresses to the next round." Sky Bet writes the same split as Void and Win/Void, and adds that on a disqualification bets on the player deemed the winner stand while bets on the disqualified player are void.
| What happens | Match winner | First set winner | Total games |
|---|---|---|---|
| Retires at 3-4 in the first set | Void at both | Void (set not finished) | Void (not decided) |
| Retires at 6-3, 1-2 (after the first set) | Opponent's backers win; retiring player's backers: void at Sky Bet (Win/Void) | Stands: settled on the 6-3 set | Void unless the line had already been passed, check your bookmaker |
| Walkover: match never starts | Void | Void | Void |
The practical point: a bet on an outsider whose opponent is carrying an injury becomes a winner if the favourite stops after the first set, even at 0-6, 0-1. The same retirement two games earlier would have returned your stake. The wider rules for football, cricket and other sports are in our abandoned match betting rules guide.
Tie-breaks in total games and set betting
A normal tie-break at 6-6 is already inside the set score: a set won 7-6 counts as 13 games, whatever the tie-break score was. The trap is the championship or match tie-break, the first-to-ten shoot-out played instead of a final set in most doubles and in some other formats. Sky Bet's wording is direct: such a tie-break "will only count as 1 game". Midnite's is that "Tie break points will not be counted for total game points markets".
The match: 6-4, 4-6, then a match tie-break won 10-8.
Total games: 6 + 4 + 4 + 6 + 1 = 21. Over 21.5 loses and under 21.5 wins. Counting the eighteen tie-break points as games would give 38, which is not how any of the rules read here settle it.
Set betting: Midnite states that set markets include the tie-break, so the match above is a 2-1 result. If the number of sets is changed from the one advertised, Sky Bet voids set betting but lets match bets stand.
A related market, "Tie-break in match? Yes/No", has its own small print: at Sky Bet "only conventional tie-breaks played at 6-6 in a set count", so a match tie-break does not make it a Yes.
Walkovers, withdrawals and outrights
A walkover is a match that never starts. Under a first-set rule it can never reach the point where a result is settled, so bets on it are void. Midnite also states that if a player retires hurt or gives a walkover before the match, selections specific to that player and match are void. If a match is postponed, bets stand as long as it is played later or an official result is declared.
Tournament outrights work differently. Sky Bet voids outright bets on a selection that does not take part, but once a player has started the event, a later withdrawal normally settles an outright bet on him as a loser. At the ATP Finals a player who withdraws from a round robin match after the first round cannot reach the semi-finals, which can end an outright and a "to qualify" bet at the same moment. How outright and each-way terms are settled is in outright betting explained.
Retirements in accumulators
A void leg in an accumulator is treated as odds of 1.00, so the bet carries on with the remaining selections. Take a 10 pound treble at 1.50, 1.80 and 2.10: if all three win it returns 56.70 pounds. If the 1.80 match ends in a first-set retirement, that leg is void and the bet becomes a double at 1.50 x 2.10 = 3.15, returning 31.50 pounds if the other two win.
Had the same player retired one set later, the leg would have been settled, as a winner or a loser depending on which side you backed. Our accumulator calculator handles void legs, and the doubles and trebles calculator shows every combination when one leg drops out.
The same problems in other sports
Retirements, walkovers and unfinished matches are not a tennis problem only. Every sport has its own version, and the rule that settles it is rarely the same:
- Snooker betting rules: what a retirement does to match, frame handicap, correct score, total frames and highest break bets.
- Darts betting rules: unfinished matches, tied 180s and handicaps that land exactly on the number.
- Golf betting rules: players who withdraw after teeing off, dead heats for the last each-way place and events cut to 54 holes.
- Boxing betting rules and UFC and MMA betting rules: retirements between rounds, technical decisions, draws and the half-round rule.
- Basketball betting rules: overtime counts in some markets and not in others, including player props.
- Horse racing betting rules: non-runners, Rule 4 deductions, Best Odds Guaranteed and first past the post.
- F1 betting rules: post-race penalties, red flags and head-to-heads when both drivers retire.
Frequently asked questions
What happens to my tennis bet if a player retires?
It depends on when the player retires and on your bookmaker's rules. At Sky Bet and Midnite, two UK-licensed bookmakers, a match winner bet is void if the retirement comes before the first set is finished. Once the first set is complete, the match is settled in favour of the player who goes through to the next round, so a bet on the opponent of the retiring player wins. Markets that were already decided before the retirement, such as the first set winner, stand at both. Other bookmakers still use a different rule, so read yours before you bet.
What happens to a tennis bet if the match is a walkover?
A walkover means the match never starts, so it can never reach the end of the first set, which is the point at which both Sky Bet and Midnite stop voiding retirements. Bets on that match are therefore void and stakes are returned. Midnite also states that if a player retires hurt or gives a walkover before the match, selections specific to that player and match are void. A tournament outright bet on a player who withdraws before playing is a separate case: Sky Bet voids outright bets on a selection that does not take part.
Does a tie-break count as a game in total games betting?
A normal tie-break at 6-6 is part of the set score, so a set won 7-6 counts as 13 games. A championship or match tie-break played instead of a final set is counted as one game: Sky Bet's rules say it 'will only count as 1 game', and Midnite says tie-break points are not counted in total games markets. So a match that finishes 6-4, 4-6, 10-8 in a match tie-break totals 21 games, not 38.
Are tennis bets void if the surface or venue changes?
Bookmakers disagree. Sky Bet's general rules say all bets stand if the venue changes, if a match moves from an indoor court to an outdoor court or the other way round, or if the surface changes before or during the match. Midnite says that if the venue or surface is changed from the one advertised, all bets on that match are void. This is the clearest case where the same event settles differently at two UK bookmakers.
When are the ATP Finals and the Davis Cup Final 8 in 2026?
