Tyler Marsh
Tyler Marsh writes the Duel guide on loadopsai.com. He has covered crypto casinos since 2021 and previously reported on CS:O skin-betting, which is how he knows the track record of founder Ossi "Monarch" Ketola and his earlier site CSGOEmpire.
His background
Tyler's first beat was skin-betting around CS:GO, where he followed the same operators that later moved into crypto casinos. That history matters on this page: Duel is run by Immortal Snail LLC, registered in Charlestown, Nevis under L22982, with an Anjouan licence ALSI-202411026-FI1, and it opened on 18 July 2025. Knowing what happened to the operators he covered between 2017 and 2021 gives him a baseline for reading a new launch. He does not treat a familiar name as proof. It only tells him which questions to ask first.
How he checks a casino
Tyler opens a real account wherever the terms allow it, funds it, bets, and times withdrawals with a stopwatch. He reads the terms line by line rather than summarising the promotional page, and he re-checks every page he publishes. The last full check of this Duel guide was 8 October 2026.
Where he cannot open an account, he says so plainly. He states the restriction, points to our restricted countries list, and stops there rather than guessing at what an untested feature does.
What he measured on Duel
- Rakeback timing. Whether the 50% house-edge share really credits on every bet, instantly, with no wagering and no cap, and whether it can be withdrawn at once.
- Zero-edge allowance. Whether the Duel Originals 0.1% edge holds, and whether the daily allowance behaves as advertised at $1,000 per bet and $50,000 per day.
- Payments. All 23 crypto networks tested for deposits and withdrawals, minimum bet down to $0.01, and the ID check threshold at €5,000 lifetime deposits or the first withdrawal.
- Support. Response times across the 24/7 live chat at duel.com, plus the Discord and Telegram channels.
Editorial independence
Partner links on this site pay us. Verdicts are not for sale. No operator, Duel included, sees a page before it goes live, and no operator can pay to change a score, a measurement or a date. If a fact changes, we change the page and stamp the new check date on it.
We are an independent review site, not Duel, and nothing here should be read as a offer from the casino itself. Gambling is for adults only — see our 18-plus policy and our notes on responsible gambling. If you spot an error, write to [email protected] or use the contact page. We answer, and we correct in print.
