What makes a good online casino

Five things can be scored. A few cannot.

Key takeaways

  • Offer terms, not offer size.
  • Games: choice and RTP.
  • Payments: speed for verified customers.
  • A licence is the entry ticket, not a score.

The five categories

CategoryWhat earns a high score
Welcome offerLow or no wagering, few conditions, fair deadlines
Slots and gamesA large library from established studios
Live casinoSeveral studios and a range of tables
PaymentsCommon methods and quick payouts to verified customers
MobileApps and a site that work well on a phone

What is not scored

The licence is not scored because it is not optional: every casino here holds one, and a casino without one would not appear at all. Customer service and how disputes are handled are not scored either, because we cannot assess them without real accounts.

Why so many ties

Licensed casinos of this size are more alike than their adverts suggest. Four of our five score 8.5 for live casino and for mobile. When scores tie, the difference lies in details such as which studios, which payment exclusions and which deadlines.

The sixth category

Fit. A casino can score well and still be wrong for how you play.

Scores are desk-based: they draw on each casino's published terms, the public register and recent independent reviews, not on real-money accounts. Where scores tie we say so and name the tie-break. Offer terms dated 5 October 2026. How we score. 18+. Free help: 0808 8020 133 or safer gambling.
