Complaints and issues
What players report going wrong at Duel, which complaints hold up under examination, and what recourse actually exists under an offshore licence. This page exists because leaving it out would make the rest of the site untrustworthy.
Read this first
Everything below is secondhand. We tested this casino ourselves and never had a balance frozen, a payout refused or an account locked — which means we cannot tell you from experience how the operator behaves under pressure. That is a real gap in our coverage and it is stated plainly on the methodology page as something we do not test.
Complaints about online casinos are also unusually unreliable as evidence. A player who breached the terms rarely says so. A player who lost a large amount sometimes concludes the games are rigged. Competing operators and affiliates seed negative reports. And genuine failures are underreported, because someone whose balance vanished frequently walks away rather than posting about it.
So what follows is patterns rather than verdicts.
What people actually report
Voided balances after geographic breaches
By far the most common category, and the one where the reports and the terms agree. A player registers from or accesses the account from a restricted country, plays for weeks or months without incident, and the problem surfaces at the first significant withdrawal.
This is not the casino behaving unexpectedly. It is written into the terms, and every offshore operator has the same clause. What makes it feel like a trap is the delay: everything works normally right up until the money tries to leave. The full country list is on the restricted countries page and reading it before a first deposit is the single highest-value five minutes available.
Recourse in these cases is close to nil. The player breached the terms, the operator is entitled to act, and there is no regulator who will take the other view.
Accounts flagged as shared or duplicate
Second most common. Multiple accounts from one device, one IP or one funding wallet. Sometimes genuinely one person, sometimes a household sharing a connection — and the flag does not distinguish between those two well.
Where it is a genuine false positive, support has reportedly resolved it. Where multiple accounts existed, the outcome tends to be poor. Rakeback has no cap and no tier, so there is no advantage to a second account in the first place.
Withdrawal delays attributed to the casino
A large share of complaints in this category turn out on inspection to be Bitcoin during congestion. The transaction was broadcast, the fee was low relative to the mempool, and it sat pending — which looks identical to a casino stalling if you do not check a block explorer.
The distinguishing test is simple: if the withdrawal was approved and a transaction hash exists, the delay is the network. If approval itself has not happened, that is a compliance question. Median timings per chain are on the withdrawals page.
Chargeback suspensions
A smaller cluster, entirely predictable, and entirely self-inflicted. Buying crypto through the cashier with a card and later disputing the charge suspends the account and triggers verification. The card network's rules override the casino's relaxed identity policy at that point.
Rigging accusations
These appear for every casino that has ever existed and are almost always a losing streak plus frustration. The unusual thing about Duel is that the accusation is testable on the in-house games: seeds are published, and anyone can recompute a round with an independent hash tool.
We have not seen a rigging claim about the Originals accompanied by a failed verification, which is what evidence would look like. The walkthrough is on the provably fair page, and it takes about two minutes.
What recourse exists
Honestly: not much, and this is the central weakness of the entire proposition.
Immortal Snail LLC holds permit ALSI-202411026-FI1 from the Anjouan Gaming Authority. That is a genuine licence with genuine conditions. It is not a UKGC or MGA licence, and the difference is not a technicality — it is whether a body with resources, a mandate and enforcement powers will take up your case.
If a balance is frozen and support stops responding, the practical options are: escalate to the licensing body and accept that response times and outcomes are uncertain; publish the case with documentation, which occasionally moves an operator that cares about reputation; and that is close to the end of the list. There is no ombudsman, no chargeback route on a crypto deposit, and no court that will hear it economically.
This is the actual cost of the privacy described on the no-KYC page. The same licence that permits an email-only signup is the licence that leaves you without recourse. They are one fact viewed from two sides, and anyone presenting the first without the second is selling.
How to protect yourself
Check the country list before depositing. This prevents the most common failure entirely.
Test a small withdrawal early. Before building any balance you would mind losing. This converts the worst outcome into a minor one.
Turn on two-factor authentication. Registration takes only an email, which is what makes signup fast — and it also means email plus password is all that protects the balance until you enable 2FA. It is in the security settings and takes a minute.
Keep records. Transaction hashes, chat logs, screenshots of terms as they stood. If a dispute ever happens, this is the entire difference between a case and an assertion.
One account, from one permitted country, on one device. Nearly every complaint above is downstream of breaking one of these.
Report something
If something happened to your account that looks systematic rather than individual, the contact page reaches us. We cannot intervene — we are not the operator and have no access to anything — but patterns are worth documenting, and this page gets updated when they emerge.
