Esports Surebet Scanner: CS2, Dota 2, Valorant
Dozor finds esports surebets in Live and Prematch across dozens of bookmakers: maps, rounds, kill totals. About 500 an hour; half last two seconds.
Esports produces more surebets than traditional sports, and they are shorter-lived. There are two reasons: every match has dozens of markets on maps, rounds and kills, and bookmakers update their lines on them at different speeds. Over 20 hours on September 5–6, 2026, the Dozor scanner recorded 10,000 surebets on esports and prediction markets, about 500 an hour. The median lifetime was 2.1 seconds.
Which games
CS2, Dota 2, League of Legends and Valorant, plus second-tier tournaments in each. It's in the second tier that discrepancies are more frequent: there are fewer public stats, bookmakers' analysts disagree more, and lines are updated less often.
Which markets produce surebets
| Market | Share of surebets per day | Notes |
|---|---|---|
| Handicap (maps and rounds) | 33% | many numeric lines, books often disagree |
| Match and map winner | 25% | the most liquid market, shortest-lived |
| Map and round totals | 20% | cross lines create surebets between different totals |
| Team totals | 8% | updated less often than the main total |
| Match round handicap | 4% | CS2 and Valorant |
| Total kills | 3% | Dota 2 and LoL, lives eight times longer than the rest |
Total kills stands apart: a median lifetime of 16 seconds versus two for the other markets, and one in five surebets lasts longer than a minute. Bookmakers price it less accurately and update it less often.
How esports surebets are different
- Lower limits. On a CS2 second-division match, many books' maximum stake is several times lower than on football. The stakes from the calculator run into the limit.
- Settlement rules differ. Overtime on a map, a forfeit, a map replay, a pause in Dota 2: two books settle the same market differently. Before a map surebet, open both books' rules.
- Live is faster. A CS2 round lasts under two minutes, and in Dota a kill happens every few seconds. A line that hasn't caught up with an event is the source of most surebets, and it catches up within seconds.
- More bookmakers. Besides traditional bookmakers, esports is covered by crypto platforms (Duel, Thunderpick, BC.Game, CSGOEmpire, Shuffle, Roobet) and prediction markets. Different odds suppliers mean different prices, and therefore surebets. In one day, Dozor found them across 27 books in 342 different pairs.
What Dozor does
It reads the lines of all connected bookmakers at once, normalizes markets into one format (the same map handicap is named five different ways at five books), links matches across books and shows pairs of outcomes where the sum of inverse odds is below one. The card shows the event, game, market, both legs with their books, ROI, the age of each price and the stake split. Live and Prematch on one screen, updates within 0.1 seconds, notifications in the browser and Telegram.
Frequently asked questions
Why are there more surebets in esports?
Live lines are moved by algorithms after every round, books take their odds from different suppliers, and fewer models price the map and kill markets. Shares by game and market are in the article “Esports Arbitrage Betting: Where and Why Bookmakers Disagree”.
Are there prematch esports surebets?
Yes: they appear less often and live longer. Most of the volume is in live, when lines move every second. More on the modes: Live surebets and Prematch surebets.
Which bookmakers are connected?
Russian ones (Winline, Fonbet, BetBoom, Olimp, Pari, Betcity, Marathon, Leon and others), international ones (Pinnacle, 1xBet, Melbet), crypto platforms and the prediction markets Polymarket and Kalshi. Brands that share an odds supplier don't form surebets with each other, and the scanner doesn't show such pairs.
How many surebets a day can you actually bet?
Of the 500 an hour, about 25 last longer than a minute. Those are the ones a person with notifications can catch. The rest are visible to the scanner but out of reach for a human.
Is it suitable for beginners?
A card reads in seconds, terms are explained in the glossary, and stakes are calculated by the calculator and by the scanner itself. It's best to start with prematch and kill totals: there's more time to check.
A breakdown for every book and pair is in the Bookmakers section, recalculated daily.
