Most online casinos are legitimate businesses. They make money from the house edge and have no reason to cheat players — doing so would cost them their license. But a small number operate as short-term cash grabs, designed to accept deposits and never pay out. This guide is about spotting those casinos before you deposit, not after.
Every licensed casino shows its license number in the footer. Click it — a legitimate license links to a public verification page on the regulator's own domain (e.g. authorisation.mga.org.mt for Malta, gaminglicences.com for Curacao, gambling.is for Isle of Man).
Red flags within this red flag:
"Max cashout: €100" on a bonus looks reasonable until you realise it means if you win €5,000 from the bonus, you only cash out €100 and the rest is voided. Any bonus with a cashout cap under the bonus amount × 5 is a bad deal. Any casino that hides this cap deep in the T&Cs is worse.
Industry standard is 30–45x. When you see 70x, 100x, or even 200x wagering, the casino has mathematically ensured you cannot clear the bonus with a positive EV. These bonuses exist purely to trap players into playing longer than they would without a bonus — not to offer value.
Normal KYC: you upload documents once, get verified within 72 hours, and never hear about it again. Rogue KYC: you're verified, then after winning €10,000 the casino "requires additional documents" — your tax returns, your last 12 months of bank statements, a selfie holding your passport and a hand-written note with today's date.
This is not compliance. This is stalling — hoping you'll either give up or lose the balance back playing while you wait. If KYC escalates suspiciously after a big win, document everything and escalate to the regulator immediately.
Search the casino name + "review" on Google. A legitimate casino will have reviews on AskGamblers, CasinoMeister, Trustpilot, and Reddit (r/onlinegambling). A new legitimate casino might have fewer, but they'll exist. If the only hits are the casino's own blog posts and affiliate sites, treat the casino as unverified — don't deposit more than you'd be comfortable losing.
You can check a domain's age at whois.domaintools.com. Under 6 months old + no reviews = extreme caution.
A surprising number of rogue casinos copy the logo, colour scheme, and domain of a legitimate casino — stakebet.com instead of stake.com, bc-game.io instead of bc.game. Always type the URL yourself or use a trusted review site's link — don't rely on a Google ad that might lead to a cloned site.
A real casino has a real customer support team — live chat with humans during business hours at minimum, 24/7 at the top-tier sites. If every support channel routes you to a chatbot that can't resolve anything, and email replies take a week, you'll have no recourse when you actually need help.
Test this before you deposit. Message support with a simple pre-sales question. If the response is useless or takes days, don't deposit.
Most legitimate casinos version their terms with a "last updated" date. Some rogue casinos update their terms retroactively — the bonus you claimed last week now has different wagering requirements, or your withdrawal method is no longer supported.
Before claiming any bonus, save a PDF copy of the terms. If the casino later cites a rule that wasn't there when you signed up, you have proof.
Crypto-only is fine for legitimate casinos. What's not fine is a casino that accepts crypto deposits with no published withdrawal methods — or with withdrawal minimums set so high (e.g. "€5,000 minimum withdrawal") that normal players can never cash out.
Legitimate casinos advertise on licensed channels and through regulated affiliates. If the casino is spamming you on Telegram, Discord, or WhatsApp, if it's paying influencers without "#ad" disclosure, or if it's running ads targeting people in countries it doesn't accept players from — these are signals of a disregard for compliance. Where compliance is disregarded in marketing, it's often disregarded in payouts too.
Before your first deposit at any new casino, run through this:
If all 10 are ticked, the casino is very likely legitimate. If more than 2 are unticked, find a different casino.
