About Us
Sites Not On Gamstop is an independent research site for adults in the UK who want to understand casinos that operate outside GAMSTOP before they sign up. We explain how these sites work, what their bonuses really require, and where the risks sit. This page tells you who we are, what we do, and how far you can rely on it.
What this site is for
Many readers arrive knowing little about how a casino that is not on GAMSTOP differs from a UK-licensed one. Our aim is to close that gap in plain English. We cover:
- Casino features, games and software providers
- Bonuses, wagering requirements, maximum bet rules, expiry dates and cashout limits
- Payments in GBP, currency conversion, fees, withdrawal limits and processing times
- Sports betting, including decimal odds, accumulators and cash-out
- Complaints routes, customer support and player protection tools
Our main comparison is on our guide to non GamStop casinos. This page explains the thinking behind it.
Commercial disclosure
We may earn a commission if you register with an operator through links on this site. That is how the site is funded. Commission does not buy position: rankings and editorial ratings are set by our assessment, not by what a brand pays. Editorial ratings are our own scores. They are not customer-review scores. The list of casinos is supplied by the publisher, and we then review and rank it.
How we research and rate casinos
We have not staked money or claimed to have played, deposited or withdrawn at any casino for this site. Our work is research: we read published terms, licence information, payment and bonus pages, and support details, then compare them. Where we can verify a fact, we say so. Where it is only casino advertising, we label it as advertised. Where something is unresolved, we say that too. Time-sensitive findings carry a date; this page was last fact-checked on 29 September 2026.
We look at these factors:
- Licensing and ownership – which overseas licence is stated, who is named as operator, and whether that can be checked with the issuing body.
- Bonus terms – wagering requirement, game contribution, maximum bonus bet, expiry and cashout cap.
- Payments – minimum deposits, GBP account availability, fees, conversion, withdrawal limits and stated processing times.
- Verification – KYC, identity and source-of-funds checks, and how withdrawal disputes are handled.
- Games and betting – slots, live dealer, table games, sportsbook and whether one wallet covers both.
- Support and protections – contact options, complaints procedure, deposit and loss limits and self-exclusion.
The casinos we currently feature
The operators at the top of our list are Betmica, Kikibet, Betninja, WinnerIsland, Zombillion, Smash Casino, Nightluck, CoinPoker, Rivo and Daytonaspin. All are shown with headline offers as advertised, so treat the figures as marketing until you have read the full terms. Many are quoted in euros or dollars, so check whether a GBP account is offered or whether conversion fees apply.
| Casino | Advertised headline | Editorial rating |
|---|---|---|
| Betmica | 570% up to £5,700 + 270 free spins | 10.0 |
| Kikibet | 350% up to 5,555 £ and 300 free spins | 9.9 |
| Betninja | £1,000 bonus and 100 free spins | 9.9 |
Even the highest-rated site has drawbacks. Large percentage bonuses usually carry heavy wagering and caps we cannot confirm without reading current terms, and none of these operators offers the protection of GAMSTOP registration or the UK Gambling Commission.
What "not on GAMSTOP" means in practice
GAMSTOP is the national self-exclusion scheme for licensed operators in Great Britain. A casino not on it is generally licensed elsewhere, often in an overseas jurisdiction such as Curaçao. Accepting British customers is not the same as being authorised by the UK Gambling Commission to serve them. That means UK-style rules, complaint routes and dispute schemes may not apply. Your GAMSTOP exclusion will not stop you using these sites, which is exactly why they carry extra risk. We never describe any casino as completely safe and never guarantee withdrawals or winnings.
Who we are for, and who we are not for
This site is for adults aged 18 or over who want to compare terms with open eyes. It is not for anyone who has self-excluded to stop gambling. If that is you, please leave these sites alone and read our responsible gambling page, which lists support such as GamCare and blocking software. Gambling is not a source of income or a fix for money worries.
