Crypto Sportsbook Arbitrage: Stake, BC.Game, Thunderpick
Arbitrage betting with crypto sportsbooks: 30 days of Dozor data on Stake, BC.Game, Thunderpick, Duel and Roobet, feed groups, and what each book's terms say.
Contents
Short answer
Crypto sportsbooks differ a lot as a source of esports surebets: over 30 days Duel and Thunderpick each took part in almost 800,000 surebet episodes in Dozor's data, Stake in 32,572 and Roobet in 13,010 — and the published sports rules of Duel, Roobet and BC.Game, three brands on BetBy, prohibit arbitrage betting outright. Over October 6 – November 5, 2026, the longest-lived surebets among these books were at Roobet (8.5% of episodes lasted over a minute) and Duel (7.0%); at Thunderpick only 2.6% did, because most of its surebets are with 1xBet in CS2 live and close within seconds.
Each book is a separate company with its own licence, list of restricted countries and verification rules; below they are quoted from each book's terms with links, checked on November 6, 2026. Whether betting with them is allowed where you are depends on your country's law and the operator's licence — official sources for the US, the UK, Canada and Australia are in Is arbitrage betting legal? This is not legal advice.
Crypto books Dozor tracks
| Book | Feed group | Episodes, 30 days | Over a minute | Median lifetime | Prematch share | Top international partners |
|---|---|---|---|---|---|---|
| Duel | BetBy | 799,389 | 7.0% | 2 s | 9.3% | 1xBet, Polymarket |
| Thunderpick | own | 788,854 | 2.6% | 2 s | 5.0% | 1xBet, GGBet |
| Gamdom | Oddin | 311,413 | 3.0% | 0 s | 5.3% | 1xBet, 1win |
| BC.Game | BetBy | 195,267 | 5.7% | 0 s | 9.5% | 1xBet, Thunderpick |
| Shuffle | Oddin | 107,686 | 4.1% | 0 s | 8.0% | 1xBet, Duel |
| CSGOEmpire | BetBy | 47,334 | 2.8% | 0 s | 23.3% | 1xBet, Thunderpick |
| Stake | own | 32,572 | 5.0% | 0 s | 9.0% | 1xBet, Gamdom |
| Roobet | BetBy | 13,010 | 8.5% | 0 s | 35.3% | 1xBet, Thunderpick |
A median of 0 s means more than half of a book's surebets were caught in a single 2-second snapshot of the scanner. 1xBet is the top partner of every book in the table: Thunderpick and 1xBet alone gave 533,274 episodes, but only 0.2% of them lasted over a minute. The longest-lived crypto pair is Duel and Thunderpick: 23,390 episodes, 38.1% over a minute, a median of 10 seconds.
Feed groups: one line, no surebets
Several crypto brands take their odds from the same supplier. Duel, BC.Game, Roobet, CSGOEmpire and Reels run on BetBy; Gamdom and Shuffle on Oddin. Brands of one feed group differ only by update timing, so Dozor doesn't count surebets between them: Duel and BC.Game give you one view of a match, not two. Thunderpick and Stake have their own lines and do form surebets with BetBy and Oddin brands, for example Duel – Thunderpick and Stake – Gamdom (6,055 episodes). More in the feed group glossary entry.
Limits, verification and restricted countries
Quoted from each book's own terms, checked on November 6, 2026. Lists of restricted countries are shortened to examples; the full list and its current version are on the book's site.
| Book | Licence, as stated | Not available in, per its terms (examples) | Verification | Arbitrage in the terms |
|---|---|---|---|---|
| Duel | licensed in Anjouan, per its terms | Australia, France, Germany, the Netherlands, Spain, the UK, the US and others (terms of service) | may be requested "before processing a withdrawal" | prohibited (sports betting rules, "Arbitrage Betting") |
| BC.Game | Anjouan, ALSI-202410011-FI1 | Australia, Austria, France, Germany, the Netherlands, Spain, the UK, the US and others (§4.3); its KYC guide also lists "Brazil (temporary)" among unsupported regions | "before, during or after Your use of the Services" (§6.1) | prohibited (sports rules §7.4.4) |
| Roobet | Curaçao, OGL/2024/687/0427 | Australia, Cyprus, Malta, the Netherlands, the United States, the UK and others (§3.5) | "at any time" (§4.9) | prohibited (sportsbook policy §7.4.4); bets may be voided (§13.5) |
| Shuffle | Curaçao, OGL/2024/1337/0628 | Australia, France, Germany, the Netherlands, Portugal, Spain, Sweden, the UK, the US and others (§8.3) | "at any time", and in any event before the first withdrawal (§5) | bets may be voided for "arbitrage or matched betting" (§12.4) |
| Gamdom | Anjouan, ALSI-152406043-FI4 | Australia, Austria, Belgium, France, Germany, the Netherlands, Portugal, Spain, Sweden, the UK, the US and others (§3.4) | "at any time thereafter, especially when specific financial thresholds are met" (§2) | not mentioned; one account per user (§2.3) |
| CSGOEmpire | Curaçao, OGL/2024/1183/0869 | Australia, France, Germany, the Netherlands, Spain, the UK, the US and others (terms of service) | "at the latest once your cumulative deposits and withdrawals reach 4500 coins" | not mentioned; obvious odds errors may be voided |
- BetBy rules (Duel, BC.Game, Roobet): arbitrage "is strictly prohibited on the Sportsbook", and users "found engaging in arbitrage betting will face immediate cancellation of the Bets and permanent restrictions" (§7.4.4 at BC.Game and Roobet; Duel's copy has no section numbers); maximum stake limits can change "for any Event, Market, Operator, or End User individually" (§7.1.3). The same rules prohibit "any automated systems (including, but not limited to, robots, bots, scanners, or similar automated tools)" used "to place or assist in placing Bets" (§3.6).
- Stake and Thunderpick: their terms were behind a browser check and could not be read on November 6, so we don't quote them; read them on the book's site before depositing. Stake's help center says only that "The odds provider may void bets placed on incorrect offers as outlined in the sportsbook rules."
- Crypto payments can be regulated by country law. For example, Australia's Interactive Gambling Act 2001 makes it an offence for a regulated interactive wagering service to accept payment in digital currency from a customer physically present in Australia (section 15C, with exceptions in the Act).

Esports markets by book
| Book | CS2 share | Next games | Most frequent surebet markets |
|---|---|---|---|
| Duel | 76% | Dota 2 11%, Valorant 9% | Handicap, Total, Winner |
| Thunderpick | 82% | Valorant 9%, Dota 2 6% | Handicap, Team 2 total, Team 1 total |
| Gamdom | 80% | Valorant 9%, Dota 2 6% | Team 2 total, Handicap, Team 1 total |
| BC.Game | 79% | Valorant 11%, Dota 2 4% | Handicap, Total, Match rounds handicap |
| Shuffle | 70% | LoL 13%, Dota 2 10% | Handicap, Winner, Team 1 total |
| CSGOEmpire | 53% | LoL 20%, Dota 2 13% | Winner, Handicap, Total |
| Stake | 87% | Dota 2 5%, Valorant 4% | Odd/even maps/rounds, Team 1 total, Handicap |
| Roobet | 49% | LoL 29%, Valorant 11% | Handicap, Total, Winner |
Shares are of each book's surebet episodes over the same 30 days. CS2 dominates everywhere — 79% of all episodes in Dozor's data — but CSGOEmpire and Roobet get a fifth to almost a third of their surebets from League of Legends; at Roobet, total towers and total inhibitors are among the five most frequent markets.
Pairs with prediction markets
Some crypto books also pair with exchanges:
| Pair | Episodes, 30 days |
|---|---|
| Duel – Polymarket | 59,517 (12.0% over a minute, median 2.1 s) |
| Duel – Predict.fun | 35,697 (9.4% over a minute, median 4 s) |
| Duel – Kalshi | 10,456 |
| Shuffle – Polymarket | 5,373 |
| Shuffle – Predict.fun | 4,914 |
| CSGOEmpire – Polymarket | 3,728 |
Surebet ROI with exchanges in Dozor is net of the taker fee. Polymarket and Kalshi are not available in every country; their own restriction lists and fees are in Polymarket and Kalshi arbitrage.
FAQ
Is arbitrage betting allowed at crypto sportsbooks?
It depends on the book's terms. The BetBy rules published by Duel, BC.Game and Roobet prohibit it; Shuffle may void a bet if it suspects arbitrage; the terms of Gamdom and CSGOEmpire don't mention arbitrage, but let them set stake limits or void bets on obvious errors. A voided leg breaks the surebet, so read both books' terms before you bet.
Do crypto sportsbooks ask for ID?
The terms of every book we could read reserve the right to verify identity: at any time (Roobet, Shuffle, BC.Game), before a withdrawal (Duel, Shuffle) or once financial thresholds are met (Gamdom, CSGOEmpire).
Why are there no surebets between Duel and BC.Game?
They take odds from the same supplier, BetBy, so their prices move together. The same goes for Gamdom and Shuffle on Oddin.
Which crypto sportsbook has the longest-lived surebets?
In Dozor's data for October 6 – November 5, 2026: Roobet, with 8.5% of episodes over a minute, and Duel, with 7.0%. Among pairs, Duel – Thunderpick: 38.1% over a minute.
