What “certified” actually means
There is no single “certified casino” badge. In practice it means three separate checks:
- A gambling licence: issued by a regulator such as the Malta Gaming Authority, the UK Gambling Commission or the Curaçao Gaming Authority. The licence sets rules on fair play, player funds and complaints.
- Tested games: independent labs such as eCOGRA, iTech Labs and GLI test random number generators and game payouts.
- Secure connections: SSL encryption protects your login and payment details. Look for the padlock in your browser.
Some crypto casinos also offer “provably fair” games, where you can check each result yourself with a cryptographic hash.
How to check a casino’s licence
- Scroll to the footer and find the licence statement and number.
- Click the regulator’s seal. A real seal opens a validation page on the regulator’s own site.
- If the seal doesn’t click through, look up the company name or licence number on the regulator’s website.
- Check that the company named in the terms matches the licence holder.
- Be wary of any casino that hides its licence or shows a seal that is just an image.
Red flags to watch for
- No licence information, or a licence that can’t be verified.
- Bonus terms that are vague or change after you deposit.
- Withdrawals that are “pending” for weeks with no reason given.
- Pressure to deposit more before you can withdraw.

Certified casino FAQs
What is a certified casino?
A casino that holds a valid gambling licence and uses games tested by independent labs for fairness.
How do I check a casino’s certification?
Click the licence seal in the footer. It should open a validation page on the regulator’s website. You can also search the licence number there.
Is a Curaçao licence safe?
It is a real licence, and Curaçao has tightened its rules under the Curaçao Gaming Authority. Rules are lighter than in Malta or the UK, so also check a casino’s payout record and reviews.
Can a casino lose its licence?
Yes. Regulators can suspend or revoke a licence if an operator breaks the rules.
