Sites Not On Gamstop is an independent, research-based guide to casinos not on GamStop, written for adults in the UK who want to understand an operator's offers, restrictions and protections before they sign up. Our current focus is slots, but we also cover bonuses, payments, withdrawals, sports betting and account safety.

Commercial disclosure: the publisher may earn a commission if you join an operator through a link on this site. Commission does not buy a place in our rankings or change what we say about a brand's drawbacks. The list of casinos we feature is supplied by the publisher, and we review those selections rather than choosing them from the whole market.

What this site is for

Many readers arrive knowing little about how non GamStop casinos differ from UK-licensed sites. We aim to close that gap in plain English. We explain wagering requirements, game contribution, maximum bet rules, bonus expiry and cashout limits, so you can read a headline offer and see what sits behind it.

We don't assume you already understand licensing, identity checks or withdrawal restrictions. Where a term matters, we explain it once, clearly, and move on.

What "not on GamStop" actually means

GamStop is the national self-exclusion scheme for online gambling in Great Britain. Operators licensed by the UK Gambling Commission must use it. A casino that is not on GamStop is not part of that scheme, and it usually holds an overseas licence instead. Curaçao is a common example.

This has practical consequences you should know about:

  • Accepting British customers is not the same as being authorised to serve them. An overseas licence does not give UK Gambling Commission oversight or access to UK complaint routes.
  • If you have registered with GamStop, playing at a site outside it removes a safeguard you chose for yourself.
  • Dispute handling, limits and player protections vary by operator and licence, so they need checking each time.

Our page on responsible gambling covers self-exclusion, deposit and loss limits, blocking software and GamCare support in more detail. If gambling is causing you harm, please read it before anything else.

How we research and rate casinos

We have not claimed to deposit, play or withdraw at the casinos we cover. Our ratings come from reviewing what operators publish and what can be verified. The date of our latest fact-check is 29 September 2026. Offers change often, so treat every figure as advertising until you have read the current terms on the casino's own site.

When we assess an operator, we look at:

  1. Licensing and ownership: which licence is stated, who is named as operator, and whether that can be verified.
  2. Bonus terms: wagering requirements, game contribution, maximum bet, expiry and cashout caps.
  3. Payments: whether GBP accounts, debit cards, bank transfers, e-wallets or crypto are stated, along with fees and currency conversion.
  4. Withdrawals: stated limits and processing times, plus identity verification and source-of-funds checks.
  5. Games: slots, live dealer and table games, software providers, and RTP information where published.
  6. Support and complaints: the contact channels offered and how complaints are handled.

We try to keep three things separate: confirmed information, casino advertising, and questions we could not resolve. Our editorial ratings are our own assessments. They are not customer review scores.

Why slots are our starting point

Slots are the main draw at most of the sites we cover, and they are where bonus terms bite hardest. Slots normally count fully towards wagering, but some titles are excluded, and a bet cap often applies while a bonus is active. We look at volatility, RTP and progressive jackpots as well as the size of the offer, because a large bonus on a hard-to-clear requirement is rarely good value.

The casinos we currently feature

The publisher's current selection includes Betmica, Kikibet, Betninja, WinnerIsland, Zombillion, Smash Casino, Nightluck, CoinPoker, Rivo and Daytonaspin. Betmica is currently rated highest at 10.0 in our editorial scoring, with Kikibet and Betninja next at 9.8.

Headline bonuses on these brands are advertised in different currencies, including pounds, euros and dollars. Where an offer is not in sterling, currency conversion and bank fees may apply. Every welcome bonus carries conditions on wagering, eligibility and withdrawals, so read them in full. For the ranked list and comparisons, see our guide to non GamStop casinos.

Our limits and what we don't do

  • We don't guarantee withdrawals, winnings or that any casino is completely safe.
  • We don't present gambling as a way to earn money or fix financial problems.
  • We can't resolve disputes between you and a casino, but we can point you to the right complaint steps.
  • We don't assume a payment method or feature works in the UK. Check availability on the casino's site before depositing.

Our content is for adults aged 18 and over. Gambling laws differ across the UK, and regulatory scope is mainly Great Britain, so check your own position.
