What a verified casino means at SlotWhat
Verification is a stricter, hands-on layer on top of our scoring. A casino only earns the verified badge after a member of our team has personally confirmed that it is properly licensed, enforces identity checks, and pays real players on time. It is not an algorithm and not a paid placement; it is human sign-off that the basics genuinely work before we recommend a brand.
Our verification checklist
To reach this list, an operator has to clear every item below. If a single check fails, the casino stays off the page until it is fixed and re-tested.
| Check | What we confirm |
|---|---|
| Licence | A valid, verifiable licence from a recognised regulator |
| KYC | Identity and age checks are applied, not skipped |
| Payouts | We test a real withdrawal and time it end to end |
| Terms | Bonus and cashout rules are readable and fair |
| Support | A real person answers within a reasonable window |
Why manual checks matter
Licences can lapse, terms can change overnight, and a quick sign-up form rarely reveals how a casino behaves when you try to cash out. By testing payouts ourselves and re-reading the fine print, we catch problems that a specs table would miss. You can see the exact process, including how we time withdrawals, on our how we rate casinos page.
Verified brands sit alongside our wider casinos directory and our score-ordered top-rated list, so you can cross-check a name from more than one angle. Once you have picked a shortlist, weigh the offers in casino bonuses too. Whatever you choose, gamble within a budget you can afford to lose and use the free limit tools we describe under responsible gambling if play ever starts to feel like a chore.
Frequently asked questions
A verified casino has been checked by hand, not just by our scoring model. We confirm it holds a valid licence, applies real identity and age checks, and pays out on time by testing a withdrawal ourselves. We also read the terms and contact support. Only casinos that clear every item on the checklist earn the badge.
