I write the Duel guide on comart.site. I have covered crypto casinos since 2021, and I publish nothing I have not tested with my own account, my own wallet and a stopwatch.
How I got to Duel early
Before crypto casinos I covered CS:GO skin betting. That beat is how I know Ossi "Monarch" Ketola and his record at CSGOEmpire. When Duel opened on 18 July 2025 under Immortal Snail LLC in Charlestown, Nevis, I already had a founder to judge, not just a licence number. Licence Anjouan ALSI-202411026-FI1 and a registration number are paperwork. A track record you have watched for years is evidence.
Four steps I run on every site
- Open a real account where the terms allow it. Registration from the United States is not possible at Duel, and the terms ban US players by name, so I note that first and move on.
- Deposit small, bet small. Duel's minimum bet is $0.01, which makes this cheap to do properly.
- Time the withdrawal and read the terms line by line before I sign them, including the ID check at €5,000 lifetime deposits or the first withdrawal.
- Re-check the page monthly. Last full check: 8 October 2026.
What I measure at Duel specifically
Marketing claims are cheap. These are the four numbers I re-test and timestamp:
| Item | What I check |
|---|---|
| Rakeback | 50% of house edge returned as rakeback, credited instantly, no wagering, no cap, no expiry. I time the credit on a 4% edge slot, which should return roughly 2%. |
| Zero-edge allowance | Duel Originals run a 0.1% edge, plus a daily zero-edge allowance of up to $1,000 per bet and $50,000 per day. I confirm both limits hold. |
| Crypto networks | 23 networks for deposits and withdrawals, crypto only. Card on-ramp through Swapped is not available to US accounts. |
| Support | Response times in the 24/7 live chat inside duel.com, plus Discord and Telegram when chat is slow. |
Who pays for this site
Partner links on comart.site pay us a commission. They do not buy a score, a paragraph or a verdict. I write that the United States is closed and that roughly 30 countries, including the UK, France, Germany, Netherlands, Spain and Australia, are banned by the terms, even when that costs us traffic. I also keep responsible gambling and 18-plus notices on every review page.
