About Us

Slots Not On Gamstop is an independent research and comparison site for adults in the UK who want to understand casinos that operate outside GAMSTOP. This page explains who we write for, how we assess operators, how we are paid and where the limits of our knowledge lie. No author is credited on this page, and we make no claims about individual credentials.

What we do and why it matters to you

Many readers arrive here after self-excluding through GAMSTOP, or simply after seeing sites that advertise themselves as being outside it. Our job is to explain what that actually means: which protections you keep, which you lose, and what terms sit behind the headline offers. We publish reviews and guides covering bonuses, wagering requirements, payments, withdrawals, games and sports betting.

We are not a casino and we do not take bets. We cannot open, fund or close accounts for you. Our main list of non GamStop casinos is a starting point for your own checks, not a promise of how any operator will treat you.

A plain statement on GAMSTOP and UK regulation

GAMSTOP is the national self-exclusion scheme for online gambling with operators licensed by the UK Gambling Commission, which regulates gambling in Great Britain. Casinos that hold overseas licences, such as those issued in Curaçao, are not bound by the UK Gambling Commission's rules and generally do not take part in GAMSTOP.

That has practical consequences:

• Accepting British customers is not the same as being authorised by the UK Gambling Commission to serve them.
• Complaints and disputes usually fall under the overseas licensor and the casino's own procedure, not UK regulators or a UK-approved dispute service.
• Your GAMSTOP exclusion will not apply to these sites. If you excluded yourself to stop gambling, that matters a great deal.

If gambling is causing you harm, please read our responsible gambling page. GamCare offers free, confidential support on 0808 8020 133, and tools such as deposit limits, loss limits and gambling blocking software can help. We would rather you step back than use any site we list.

How we research and rank casinos

We have not personally deposited, played or withdrawn at these casinos, and we do not claim otherwise. Our assessments are based on reviewing each operator's published terms, licensing information, payment and support pages, and the offers it advertises. Facts were last checked on 29 September 2026. Terms change often, so always read the current conditions before you sign up.

We look at:

1. Licensing and ownership – which licence is stated, and whether the operator identifies who runs the site.
2. Bonus terms – wagering requirements, game contribution, maximum bet limits, expiry dates and cashout caps.
3. Payments – whether GBP accounts are offered, which methods apply to UK customers, fees, currency conversion and stated withdrawal limits.
4. Verification – KYC, identity and source-of-funds checks, which can delay withdrawals.
5. Games and sports betting – slots, live dealer tables, software providers, and any sportsbook alongside the casino.
6. Support and complaints – how you can reach the operator and what its complaints process says.

We separate three kinds of information: what we could confirm from official sources, what is casino advertising, and what remains unresolved. Where we could not verify something, we say so.

Reading our ratings and offer figures

The ratings on our lists are editorial scores. They are not customer-review scores and do not reflect a poll of players. The current top of our list is Betmica (10.0), followed by Kikibet, Betninja, WinnerIsland and Zombillion (each 9.9), then Smash Casino (9.8) and Nightluck, CoinPoker, Rivo and Daytonaspin (each 9.7).

Advertised bonuses look large, and some are shown in euros or dollars rather than pounds. A headline such as a percentage match up to a stated maximum only tells part of the story. Wagering requirements, expiry and cashout limits decide what you could ever withdraw. Currency conversion can also add cost if the account is not in GBP.

What the top-ranked names tell you

Betmica tops our list on editorial score and advertises a welcome offer of 570% up to £5,700 plus 270 free spins. The sums are large, which usually means the wagering conditions deserve close reading. We have not verified how those terms play out in practice, so check them before depositing.

Kikibet advertises 350% up to 5,555 £ and 300 free spins. That figure is presented in pounds, but confirm the account currency and the conditions attached to the spins. Large packages often carry maximum bet rules while wagering.

Betninja advertises a £1,000 bonus and 100 free spins to new players. It is simpler to read than a percentage match, but a flat bonus still comes with wagering and eligibility rules, and we cannot confirm every detail from advertising alone.

For fuller comparisons, see the main casino list. None of these offers is a guarantee of value, and a bonus is never a reason to gamble more than you planned.

How we are funded and why it does not buy position

Disclosure: Slots Not On Gamstop may earn commission if you follow a link and register with an operator. That is how the site pays for its research. Commission does not decide rankings, and an operator cannot pay for a higher place or a better write-up. Our scores follow the criteria above, and every operator we cover has weaknesses that we state.

The commercial relationship still exists, so treat our lists as one source among several. Read the terms directly with the operator and compare more than one option.

Who should and should not use this site

• It is for: adults aged 18 or over who want to understand the risks and restrictions of casinos outside GAMSTOP before making their own decision.
• It is not for: anyone who has self-excluded and wants to stay excluded, anyone gambling to solve money worries, or anyone under 18. Gambling is not a source of income.

Check that online gambling is legal where you live, and be aware that you are responsible for any tax or legal obligations that apply to you.
