Independent reporting on offshore casinos for UK players
A "casino not on GamStop" is an online casino licensed outside the UK, which means it is not connected to the UK's GamStop self-exclusion scheme and can accept UK players who are registered with it. That is the simple definition. The harder question is which ones are actually worth your time and money.
We take a different approach to most sites in this space: we operate our own casinos and review them openly. That gives us first-hand operational insight, and it gives you a conflict of interest we disclose on every page. What follows is the four brands we run, tested with real deposits and real withdrawals.

Disclosure: all casinos listed above are operated by the same group as this publication. We earn directly when you register and play. Our ratings reflect real deposit-and-withdrawal testing - see our methodology.
GamStop is a free self-exclusion scheme that every UK Gambling Commission (UKGC) licensed operator must connect to. Register with GamStop and you are blocked from every UKGC site for the period you choose. A casino not on GamStop holds an offshore licence instead - typically Curacao or Anjouan - so it sits outside that system.
That is not a loophole so much as a different regulatory regime. You gain access and fewer friction points; you give up UKGC dispute resolution and statutory consumer protection. It is a real trade-off, and anyone who tells you otherwise is selling something.
Every casino on this page is one we operate. We test registration and KYC, fund each one with card and crypto, time the withdrawals, read the full bonus terms, and check the licence. The score is built from six weighted categories - see our methodology. We publish the weaknesses of our own brands, not just the strengths, because a list that only flatters is useless to you.
Please think carefully before using any non-GamStop casino. GamStop exists for a reason. Free, confidential help is available at BeGambleAware.org and on the National Gambling Helpline, 0808 8020 133. Nothing on this page is worth your wellbeing.
It is not illegal for a UK resident to play at an offshore-licensed casino. The casino operates under its own jurisdiction's law rather than UKGC rules. You give up UKGC consumer protection in exchange.
Reasons vary: some want bigger bonuses or crypto banking, some find UKGC verification heavy, and some are registered with GamStop. If the last applies to you, consider whether playing here is the right choice.
Safety depends on the operator, not the label. Judge each one on its licence, track record, withdrawal reliability and transparency. We test every casino we list.
