Esports Betting Rules: Walkovers, Stand-ins, Format Changes and Overtime
Quick answer: a map awarded by walkover before it starts is void. A change of format (Bo3 to Bo1) voids everything at Sky Bet but only series-format bets at Midnite. Counter-Strike overtime rounds count for the map rounds handicap. A match not completed within 48 hours is void, except maps already played.
Esports bets fail in ways football bets never do. A team forfeits because a player's visa did not arrive, a server crash forces a remake, a coach plays as a stand-in, an organiser shortens a series on the day. Each of these has its own rule, and two UK bookmakers do not always write the same one.
This guide compares the published esports rules of Sky Bet and Midnite, both licensed by the UK Gambling Commission, then settles an overtime Counter-Strike map across the common round markets. It explains how bets are settled, not which team to back.
Two UK bookmakers, side by side
Both rule sets were read on 9 November 2026. Midnite publishes a general esports page plus game pages for Counter-Strike, League of Legends and Dota 2; where a game page and the general page differ, the game page applies. Sky Bet publishes one esports page. Your own bookmaker's house rules are the binding text.
| Situation | Sky Bet | Midnite |
|---|---|---|
| Walkover before a map starts | Map bets void; the matchup is void. | Map bets refunded; series bets refunded too unless it was a score-advantage map. |
| Surrender during a map | The team that did not surrender wins the map. | General rules: determined bets stand. Counter-Strike rules: a map won by surrender, forfeit or admin decision voids all bets on the match. |
| Format changed (for example Bo3 to Bo1) | All bets void. | Series-format bets (handicap, correct score) no action; match winner stands; map bets stand if played. |
| Stand-ins and line-up changes | All bets stand on a line-up change; a change in the number of players voids all bets. | One or two stand-ins allowed; three or more void the series; fewer than 10 players in a 5v5 voids the map and series. |
| Maps not played because the series is decided | Map bets void if the map is not played. | Void and refunded. |
| Remake after a technical fault | Bets struck before the map started stand; bets struck after it started are void unless already decided. | Decided bets stand; undecided in-play bets refunded; pre-start bets settle on the replayed map. |
| Overtime rounds | Map rounds handicap includes overtime unless stated otherwise; totals not addressed separately. | Map rounds handicap includes overtime unless stated otherwise; extra time counts wherever no draw is offered. |
| Postponed or interrupted | Void if not completed within 48 hours of the scheduled start; completed maps settle. | Series refunded if not resumed within 48 hours; maps played within 48 hours settle; outrights void only after 30 days. |
| What decides the result | Official broadcast of the publisher or event organiser; Counter-Strike player stats from the HLTV scoreboard. | Official result declared by the relevant governing body; kills from the in-game scoreboard. |
One overtime map, every round market settled
A Counter-Strike map is level 12-12 at the end of regulation. Team A wins overtime 4-2 and takes the map 16-14, so 30 rounds are played. Both bookmakers include overtime in the map rounds handicap unless the market says otherwise, and Midnite counts extra time wherever no draw is offered, so at Midnite this is how the bets settle (at Sky Bet, read the totals market wording):
| Bet | At 12-12 | How it is settled |
|---|---|---|
| Map winner: Team A | Not decided (12-12) | Wins: 16-14 after overtime |
| Map rounds handicap: Team A -2.5 | Would lose (margin 0) | Loses: margin 2 does not cover 2.5 |
| Map rounds handicap: Team B +2.5 | Would win | Wins: loses by 2, inside 2.5 |
| Total rounds: over 26.5 | Would lose (24 rounds) | Wins: 30 rounds including overtime |
| Total rounds: under 26.5 | Would win (24 rounds) | Loses: overtime rounds count |
Overtime turns a comfortable under into a loser, and makes the favourite's round handicap harder to cover, because overtime wins are narrow by design. A round handicap is a form of Asian handicap; our Asian handicap calculator shows how whole, half and quarter lines settle on any final score.
Walkovers, forfeits and surrenders
A walkover before any play is the simple case. Sky Bet voids the map bets and the matchup if a map is not played or is awarded by walkover or default. Midnite refunds map bets, and refunds series bets such as match winner and handicap too, unless the forfeited map was a score-advantage map in a format that hands one team a map head start.
Once a map has started, the two books part company. In League of Legends and Dota 2 a surrender is a normal way to end a game, and Sky Bet simply gives the map to the team that did not surrender. Midnite's general rules treat a surrendered map as completed, with determined bets standing. Its Counter-Strike page is stricter: if a map is won by surrender, forfeit or admin decision, all bets on the match are void, while round handicaps are graded on the score at the moment of surrender where they are already decided.
Disqualification for cheating voids map and series bets at Midnite, and Sky Bet voids map and matchup bets when a map is awarded or overturned for a rule breach. If you think a bet was graded wrongly after a forfeit, the order of events matters: note the time the map started and the time the forfeit was announced before you contact the bookmaker.
Stand-ins, format changes and remakes
Rosters move faster in esports than in any other sport. Sky Bet's answer is short: on a line-up change, all bets stand; only a change in the number of players voids them. Midnite counts coaches and players from outside the roster as stand-ins, allows one or two, and voids the series at three or more. A six-player rotation is not a stand-in.
A shortened series is where the difference costs most. Sky Bet voids all bets if the format changes from the announced Bo1, Bo2, Bo3, Bo5 or Bo7. At Midnite the match winner bet stands, so a team you backed to win a best-of-three still pays if it wins the best-of-one that replaced it, while a 2-0 correct score bet has no action.
Remakes follow timing. At Sky Bet, if a glitch forces a map to be remade after it started, bets struck before the map began stand and bets struck during it are void unless already decided. Midnite settles pre-start bets on the replayed map and refunds undecided in-play bets. A planned pause after which the map continues does not affect any bet.
Void legs in an accumulator
A void leg is treated as odds of 1.00, so the bet drops a fold. A 10 pound treble on three match winners at 1.80, 2.10 and 1.65 returns 62.37 pounds if all three win (1.80 x 2.10 x 1.65 = 6.237). If the second match is voided by a walkover, it becomes a double at 1.80 x 1.65 = 2.97, returning 29.70 pounds if the other two win. Our accumulator calculator handles void legs, and the margin calculator shows what a two-way esports price costs you before the match starts.
The same logic in other sports, where a void comes from a retirement or a postponement rather than a forfeit, is in tennis betting rules and abandoned match betting rules.
Frequently asked questions
What happens to an esports bet if a team forfeits?
It depends on when. If a map is awarded by walkover before it starts, Sky Bet voids the map bets and the match bet, and Midnite refunds the map bets and, unless that map was a score-advantage map, the series bets too. If a team surrenders a map already in progress, Sky Bet gives the map to the team that did not surrender, while Midnite's Counter-Strike rules say a map won by surrender, forfeit or admin decision voids all bets on the match.
Do overtime rounds count in Counter-Strike betting?
Yes, for the map rounds handicap: Sky Bet and Midnite both say it includes overtime unless the market states otherwise. Midnite's general rule is also that extra time counts wherever no draw option is offered, which covers round totals. Sky Bet's page names overtime only for the handicap, so check the market wording for totals. A map that is level 12-12 and finishes 16-14 after overtime is settled on 16-14 for the handicap, not on 12-12.
What happens if a best-of-three is changed to a best-of-one?
Sky Bet voids all bets if the format changes from the one originally announced. Midnite is narrower: bets that depend on the series format, such as match handicap and correct score, have no action, but the match winner bet stands and map bets stand if the map is played.
Is my bet void if a team plays with a stand-in?
Not at Sky Bet, whose esports rules say all bets stand on a line-up change. At Midnite one or two stand-ins are allowed, but three or more stand-ins for one team void the series, and its Counter-Strike page treats a team that changes more than two players as a different team, so bets are void unless the change was public before the market was priced.
How long can an esports match be postponed before bets are void?
48 hours at both bookmakers read here. If the series is not completed, or not resumed, within 48 hours of its scheduled start, bets are void, except maps already played, which settle normally. Midnite voids outright bets only if the whole tournament is postponed by more than 30 days.
