About Us
Non Gamstop Casinos is an independent research and comparison site for adults in the UK who want to understand casinos and betting sites that are not part of GamStop. We explain how these sites work, what their bonus terms really mean, and where the risks sit, so you can decide with the facts in front of you.
This page explains what we do, how our rankings are built, how the site is funded and what we cannot tell you. Facts on this page were last checked on 1 October 2026.
How this site earns money
We may earn a commission if you sign up with a casino through a link on this site. That relationship does not buy position. Commission does not decide rankings, and an operator cannot pay to move up or to have a weakness left out. The publisher supplies the casino selections and top lists, and we write the analysis around them.
What we cover
Our guides and reviews focus on the practical questions UK readers ask before opening an account:
- Bonuses: welcome offers, deposit bonuses, free spins, cashback and loyalty rewards, plus the wagering requirements, game contributions, maximum bet rules, expiry dates and cashout limits attached to them.
- Payments: minimum deposits, GBP accounts, debit cards, bank transfers, e-wallets, cryptocurrency, fees, currency conversion and withdrawal limits.
- Games: slots, progressive jackpots, live dealer tables, blackjack, roulette, baccarat, software providers, RTP and volatility.
- Sports betting: pre-match and in-play markets, esports, accumulators, bet builders, cash-out and free-bet conditions, explained with decimal odds.
- Protections: licensing, complaints routes, KYC and source-of-funds checks, and the tools that help you stay in control.
Our main comparison is on our guide to non GamStop casinos.
The sites we currently rank
The publisher's current top list, in order, is Betmica, Kikibet, Betninja, WinnerIsland, Zombillion, Smash Casino, Nightluck, CoinPoker, Rivo and Daytonaspin. Their headline offers and editorial ratings appear in the cards on the page. Those ratings are our own editorial scores, not customer-review scores.
Betmica
Betmica sits first on our list with a 10.0 editorial rating. Its advertised welcome offer is 570% up to £5,700 plus 270 free spins. It is the only one on the list where the headline sum is shown in pounds alongside a very large match percentage. Large matches usually come with heavy wagering, so check the requirement, the maximum bet while bonus funds are active, the expiry period and any cap on winnings before you deposit. We have not verified those terms here, and the offer may change.
Kikibet
Kikibet is ranked second at 9.9. It advertises 350% up to 5,555 £ and 300 free spins. The bonus is smaller in percentage than some rivals, which can make it easier to judge, but the same checks apply. The limitation is that the supplied information does not tell us which payment methods or GBP options apply, so confirm these on the site before you commit.
Betninja
Betninja is ranked third at 9.9. Its advertised offer is a £1,000 bonus and 100 free spins for new players. A flat figure is simpler to understand than a layered percentage match. The drawback is the same as elsewhere: the wording says all new players, but eligibility, country restrictions and wagering conditions sit in the terms, which you should read first.
The rest of the list
| Site | Advertised headline offer | Editorial rating |
|---|---|---|
| WinnerIsland | Welcome bonus up to €1,000 + 100 free spins | 9.9 |
| Zombillion | 250% up to £4000 + 200 free spins | 9.8 |
| Smash Casino | 600% up to €10,000 slots welcome package | 9.7 |
| Nightluck | €6,400 + 280 FS + 805% | 9.7 |
| CoinPoker | 150% up to $2,000 | 9.7 |
| Rivo | Slots welcome package: 1000% up to €10,000 + 25% cashback | 9.6 |
| Daytonaspin | 255% up to £4500 + 255 free spins | 9.6 |
Several offers are priced in euros or dollars. If your account is in pounds, currency conversion may apply to deposits, bonuses and withdrawals, and your bank may add its own charges. These figures are casino advertising, not confirmed outcomes.
How we assess casinos
We have not placed bets or made deposits or withdrawals, and we do not claim to. Our assessments come from reading each operator's published terms, licensing information, payment pages and help material, and comparing them on the same criteria:
- Licensing and ownership details that the operator publishes, and whether they can be checked with the issuing authority.
- Bonus fairness: wagering level, game contributions, maximum bet, expiry and cashout caps.
- Payments: methods offered, GBP availability, fees, limits and stated processing times.
- Verification: what KYC and source-of-funds checks are described, and how withdrawal disputes are handled.
- Games and betting range, including slots, live dealer and sportsbook.
- Support options and the complaints procedure.
- Responsible gambling tools, such as deposit and loss limits and self-exclusion.
We separate what is confirmed, what is advertised and what is unresolved. Where we could not verify something, we say so. Time-sensitive findings carry a date, and we recommend re-reading the current terms before you act.
What non GamStop actually means
GamStop is the UK's national self-exclusion scheme. Operators licensed by the UK Gambling Commission for Great Britain must take part. A site that is not on GamStop is generally licensed elsewhere, often under an overseas gambling licence, and accepting British customers is not the same as being authorised by the UK Gambling Commission to serve them.
That has consequences. UK-regulated protections, including the standard complaints route and the GamStop block, may not apply. Be careful with any site that implies otherwise. If you registered with GamStop to take a break, using these sites undermines that decision, and we would encourage you to think about why before you do. Our responsible gambling page covers limits, blocking software, GamCare and how to get support.
Limits of what we can tell you
- We cannot guarantee that any casino will pay out, or that any withdrawal will be approved.
- We do not describe any site as completely safe.
- Gambling is not income and is not a way to solve money problems. Only play with money you can afford to lose.
- You must be 18 or over. Bonus terms and available features can differ by country and change without notice.
