The scorecard
Every casino on our shortlist of the best non GamStop casinos is scored on five weighted categories, out of a total of 10 points.
- Licensing & safety (25%) — regulator, complaints history, KYC quality.
- Payments (20%) — deposit & withdrawal speed, fees, GBP/crypto options.
- Bonuses & terms (20%) — headline offers, wagering, max cash-out, game weighting.
- Games & providers (20%) — slot count, live dealer, jackpots, RTP transparency.
- Support & responsible play (15%) — 24/7 chat, deposit limits, cool-off, self-exclusion tools.
How a casino makes the shortlist
A site must clear a minimum bar before it can be considered for our list of the top non GamStop casinos:
- Active offshore licence (MGA, Curaçao, Anjouan, Kahnawake or Gibraltar).
- Public T&Cs with a clearly stated withdrawal policy.
- Working 24/7 live chat.
- Withdrawal limits and payout speed we could verify in test cashouts.
Sites that pass move into the deeper scoring that decides the order of our list of top casinos not on GamStop UK.
Ongoing monitoring
Ranking a casino once is not enough. We re-check every entry in our best casinos not on GamStop UK list every 90 days — faster if we see payout complaints or licence changes.
When a new non GamStop casino UK launches and passes the shortlist bar, we add it as a challenger and re-score the list. When a site’s payout speed collapses or its licence lapses, it drops out — even if it used to sit near the top.
What does not affect the ranking
- Whether we have an affiliate deal with the operator.
- The size of the commission offered.
- How much traffic the operator sends us.
