Our Methodology

Every ranking on this site follows one transparent process. We judge casinos on how well they serve a big-stake player, not on the size of a welcome banner. Here it is in full.

1. Licensing and strength first

A casino is only eligible for our tables if it holds a current UK Gambling Commission licence, verifiable on the public register, and has the financial backing to pay large wins. No licence, no listing. This guarantees fund protection, tested games and real recourse.

2. Table and stake limits

We check the real limits across slots and — more importantly for a high roller — live dealer and table games, where the meaningful headroom is. A casino that caps you low scores poorly however good its bonus.

3. VIP rewards and cashback

We work through each VIP scheme — the cashback rate, reloads, tiers and personal service — to judge what high-volume play actually earns over time. This is where the long-term value for a high roller lies.

4. Large withdrawals

We put a sizeable withdrawal through at every casino and time it, including any verification and source-of-funds checks. How a casino treats a big winner is the truest test there is.

5. Hands-on review

We register, deposit, play and withdraw at every casino, so our ratings reflect real experience rather than the terms on paper. You only learn how a casino treats high rollers by being one.

6. Independence

We earn commission on sign-ups, but it never moves a casino up the table. Rankings follow our review and the criteria above alone. We publish corrections openly — if you spot an error, tell us.
