Most bad online casinos don’t announce themselves. They look almost exactly like the decent ones, right down to the licence badge in the footer. The giveaways are small, and usually visible before you deposit if you know what to look for. Ten to close the tab on, in rough order of severity.

1. No verifiable licence

A regulator badge in the footer means nothing until you click it and land on that regulator’s own register. If the click goes to an image, the badge is decoration. Every real licence in 2026 is on a public database.

2. Unclear owner behind the site

The footer should tell you who operates the site, where they’re registered and under what number. If it doesn’t, or if it names a shell company you can’t find anywhere else, treat that as a hard no.

3. Bonuses with impossible wagering

“500% up to $10,000” with 60x on deposit + bonus is not a bonus you can clear. It’s a bonus designed to sit on your account permanently. The offer isn’t for you; the balance is for them.

4. Vague or missing withdrawal rules

A legitimate casino publishes exact withdrawal timeframes and fees for each method. If the page is worded in generalities, “withdrawals processed as soon as possible”, you have no contract to point to when things go wrong.

5. Support that hides during withdrawals

Test chat before you deposit with any real money. Ask a specific withdrawal question. If the reply is generic or takes hours, expect that behaviour on the day you actually need it.

6. Fake “secure” badges

McAfee Secure, Norton Secure and similar logos are usually decoration in 2026. What matters is a valid TLS certificate, a real licensor and a genuine complaints route. The badges impress no one who actually audits security.

7. Broken responsible-gambling tools

Try to set a deposit limit before depositing. If the form doesn’t save, doesn’t respond or emails you a “we’ll get back to you” message, the tools are for show. Regulated casinos are required to make limit-setting immediate.

8. Aggressive VIP contact after deposit

Legitimate VIP programmes exist and are usually fine. What’s not fine is a “VIP host” on WhatsApp within an hour of your first deposit offering “special bonuses” that don’t appear on the website. That’s a personalised trap.

9. Withdrawal minimums above deposit minimums

A casino that lets you deposit £10 but only withdraw at £50 is fine when you win big; it’s a friction bomb if your winning session lands at £30. The gap is deliberate.

10. Domains that keep changing

If the casino asks you to bookmark a new domain every few months, ask yourself why. Fresh domains dodge regulators, blocklists and unhappy players alike. A stable domain is a basic sign of an operator that expects to still be there next year.

FAQ

If a casino has one red flag but great bonuses, is it worth trying?

Usually no. The bonus is only real when the casino honours the payout. One red flag rarely comes alone; you just haven’t found the others yet.

How do I check a licence properly?

Click the badge in the footer. It should take you to the regulator’s own website, on their domain, with the operator’s name and number listed on the public register. Anything else is decoration.

Are Curacao casinos automatically bad?

No, but Curacao is the weakest of the mainstream licences in 2026. It doesn’t make a casino a scam; it does mean you have less recourse when things go wrong, so weigh other signals more heavily.
