About Us
Casino Not On Gamstop is an independent research and comparison site for adults in the UK who want to understand casinos that are not part of GamStop. We explain how these sites work, what their bonuses really require, and where the risks sit, so you can decide with the facts in front of you.
Offer details on this site were last checked on 29 September 2026. Bonus terms change often, so always read the current terms on the casino's own website before you register.
How we make money, and what that does not change
Some casinos we cover pay us a commission if a reader signs up through our links. That is how the site is funded. Commission does not buy position: ranking and ratings are not for sale, and a casino cannot pay to move up or to remove a criticism. The list of casinos is supplied to us by the publisher, and we write about it as an independent editor would.
Our ratings are editorial scores. They are not customer-review scores and they do not predict your experience.
What this site is for
Our purpose is to help readers understand offers, restrictions and protections. We do not tell anyone to gamble, and we never present gambling as income or as a way out of money problems. Our main guide to non GamStop casinos holds the full comparison, while this page explains who is behind it and how we work.
How we research and assess casinos
We have not tested casinos by depositing, playing or withdrawing, and we do not claim to. Our work is desk research: reading terms and conditions, licensing statements, payment and support pages, and the casinos' own advertising. Where we can verify a fact, we say so. Where it is only advertising, we label it as advertising. Where something is unclear, we say that too.
- Licensing and ownership: which licence a casino states, who issues it, and whether the operator is named.
- Bonus terms: wagering requirements, game contribution, maximum bet while wagering, expiry dates and cashout caps.
- Payments: minimum deposits, GBP accounts, debit card, bank transfer, e-wallet, PayPal and cryptocurrency availability, fees and currency conversion.
- Withdrawals: stated processing times, limits, identity verification and source-of-funds checks.
- Games and betting: slots, jackpots, live dealer tables, software providers, and any sportsbook or esports betting.
- Support and complaints: contact options and how disputes are handled.
- Player protection: deposit and loss limits, self-exclusion and links to help.
The casinos we currently feature
The casinos ranked on this site are Betmica, Kikibet, Betninja, WinnerIsland, Zombillion, Smash Casino, Nightluck, CoinPoker, Rivo and Daytonaspin. The ranking cards show each headline offer. Here is how we read three of them.
Betmica
Betmica holds the top editorial rating of 10.0 and advertises a welcome offer of 570% up to £5,700 plus 270 free spins. It is in first place for the size of its advertised package and the GBP-denominated amounts. The limitation is that a large percentage match usually comes with heavier wagering, so check the requirement, expiry and cashout cap before you accept.
Kikibet
Kikibet is rated 9.9 and advertises 350% up to 5,555 £ with 300 free spins. It stands out for the number of free spins offered. The drawback is that free spin winnings are commonly subject to their own wagering and limits, and we have not verified those conditions here.
Betninja
Betninja is rated 9.8 with a £1,000 bonus and 100 free spins advertised to new players. Its offer is smaller than those above, which some readers may prefer, since smaller bonuses often mean less to wager. The limitation is that we have no verified detail on its terms, so read them closely.
Every one of these offers is subject to eligibility, wagering and other conditions that can change. Some are advertised in euros or dollars, so currency conversion and fees may apply to UK accounts.

What non GamStop actually means
GamStop is the free UK self-exclusion scheme. Casinos licensed by the UK Gambling Commission must take part in it, and that regulator's rules cover Great Britain. Casinos not on GamStop are typically licensed overseas, and accepting British customers is not the same as being authorised to serve them under UK rules. That means UK protections, such as the Commission's complaints route, may not apply.
If you have registered with GamStop, that is a decision made to protect you. Using a casino outside the scheme undermines it. If gambling is causing you harm, please read our responsible gambling page, or contact GamCare or the National Gambling Helpline. Blocking software can also help.
Who should not rely on us alone
Our content is for readers aged 18 and over. It is general information, not financial or legal advice. No casino is completely safe, and withdrawals and winnings are never guaranteed. Only stake money you can afford to lose.
Corrections and contact
If you spot an error, an out-of-date term or a casino that has changed its conditions, tell us through our contact page. Our terms and conditions explain how you may use this site.
