Focused shortlist • Great Britain

A narrow, obsidian-clean view of a few UK casinos

Obsidian Ribbon Alliance is a small comparison-style site. We highlight a short list of casinos that state they are licensed to serve customers in Great Britain by the UK Gambling Commission (UKGC). It’s a starting point only – you should always verify everything directly with the operator.

How to read this shortlist

We don’t claim these are “the best” casinos – only that they currently present themselves as licensed for Great Britain and offer UK-facing products. Your job is to decide whether any of them are right for you, and that starts with careful reading.

Before signing up or depositing, it’s sensible to:

  • Look up the operator on the official UK Gambling Commission public register.
  • Read bonus terms in full, including wagering, game weighting and expiry.
  • Review safer-gambling tools such as deposit limits, time-outs and self-exclusion.
  • Set a clear spend limit and time limit that you can comfortably afford.

Remember the house edge

Casino games have a built-in house advantage, which means you are more likely to lose than win over time. If you choose to gamble, treat it as entertainment only. Never chase losses and never use gambling as a way to fix financial issues.

Obsidian Ribbon Alliance is an independent information site. We do not operate gambling services, handle deposits or withdrawals, or resolve disputes. We may receive a referral fee if you visit or sign up to some operators via links on this site. 18+ only.
