How We Rate Casinos
The exact method behind every ranking on this site — how we score casinos on safety, games, payouts, support and reputation.
How We Rate Casinos is one of the things worth understanding before you choose where to play. This guide explains it in plain English, with the practical detail a real player needs rather than marketing.
Why this matters when choosing a casino
The quality of a casino is felt in the details — how safe it is, how good the games are, how reliably it pays, and how well it supports you. Understanding how we rate casinos helps you judge those things for yourself rather than relying on a banner. Our how to choose a casino guide pulls the whole checklist together.
What to keep in mind
The costliest mistakes are universal: playing somewhere unlicensed, ignoring withdrawal terms, and treating gambling as income rather than entertainment. Avoid those and the rest is straightforward. Our guides to casino safety, payouts and RTP and house edge cover the essentials.

Frequently Asked Questions
Is this guide specific to UK players?
Yes. Everything here reflects UK Gambling Commission rules as they stand in 2026, including the 2025–2026 changes to stake limits, affordability checks and player protection. We only cover UKGC-licensed casinos.
How do I choose a good online casino?
Check it holds a current UKGC licence, look at the game range, payout reliability and support quality, then pick the safe, well-run site that fits how you play. Our full guide walks through the checklist.
How can I tell if a casino is safe?
Find its UK Gambling Commission licence number, usually in the footer, and confirm it on the public register. Avoid any site with no visible licence, one that skips verification, or one that pressures you to deposit. See is a casino safe.
Are online casino games fair?
At UK-licensed casinos, yes — games run on independently tested random number generators that cannot be altered. They carry a house edge, so they are fair but still favour the casino over time. See are casinos rigged.
What does RTP mean?
RTP (return to player) is the share of stakes a game pays back over the long run. A 96% RTP slot returns £96 per £100 staked on average; the rest is the house edge. Higher RTP is fairer. See RTP explained.
How fast should a casino pay out?
The best UK casinos process withdrawals within 24 hours once you are verified. Speed also depends on your method — e-wallets are usually quicker than cards. See our fastest payout casinos and payouts guide.
Do I have to verify my identity?
Yes — every UK casino must confirm your age and identity before paying out. With accurate details that match your ID it is usually quick. See verification explained.
Which payment methods are best?
Debit cards work everywhere; PayPal adds privacy and quick withdrawals; Apple Pay and Google Pay are fast on mobile; Pay by Mobile needs no card. Credit cards are banned for gambling. See our payment methods guide.
Did UK casino rules change recently?
Yes — slot stake limits (£5/£2 a spin), a statutory levy, and light affordability checks above a £150 monthly net loss all arrived across 2025–2026. Our 2026 rules guide explains them.
What should I do if I have a problem with a casino?
Raise it with the casino first; if it is not resolved, you can escalate free to an approved adjudicator such as IBAS. See our complaints guide.
How do I stay in control?
Set a deposit limit, treat gambling as entertainment rather than income, and never chase losses. Free help is available from the National Gambling Helpline on 0808 8020 133. See responsible gambling.
How do you stay independent?
