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. We explain what these sites offer, where the risks sit and what to check before you register. We do not run a casino, take bets or hold your money.

This page covers what we publish, how we assess casinos, how we are funded and where our knowledge stops. It is written so you can judge how far to rely on us.

What we publish and who it is for

Our readers are over 18 and mostly based in Great Britain. Some know a lot about gambling. Many do not, so we explain terms such as wagering requirements, withdrawal limits and identity checks without assuming prior knowledge.

Our guides and reviews cover:

• Casino bonuses: welcome bonuses, deposit bonuses, free spins, no-deposit bonuses, cashback and loyalty rewards, and the conditions attached to each.
• Payments: GBP accounts, debit cards, bank transfers, e-wallets, PayPal availability, cryptocurrency, fees and currency conversion.
• Withdrawals: processing times, limits, KYC and source-of-funds checks, and how disputes are handled.
• 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 bets, with odds shown in decimal format.
• Protection: complaints procedures, self-exclusion, deposit and loss limits, blocking software and support from GamCare.

Our main comparison is on our list of non GamStop casinos. Our focus is on US-style casino brands and offshore sites that accept UK players.

What "not on GamStop" means, and why it matters

GAMSTOP is the national self-exclusion scheme for online gambling in Great Britain. Casinos licensed by the UK Gambling Commission must take part. A casino that is not on GAMSTOP usually holds an overseas licence instead, for example from Curaçao, and is not regulated by the UK Gambling Commission.

Accepting British customers is not the same as being authorised to serve them. An overseas casino can take UK sign-ups without being under UK rules. In practice this means:

• Your GAMSTOP exclusion will not apply on these sites.
• UK-specific safeguards, such as mandatory affordability checks and access to UK dispute schemes, may not be available.
• Complaints go to the operator and its overseas licensor, which can be slower and less certain.

If you have registered with GAMSTOP because gambling was causing you harm, these sites are not a workaround we would encourage. Please read our responsible gambling page first. GamCare offers free, confidential support on 0808 8020 133.

How we research casinos

We have not tested these casinos with our own money, and we do not claim to have deposited, played or withdrawn. Our assessments come from reading each casino's published terms, licence information, payment pages and support details, and from checking them against what is publicly reported. Where advertising and terms differ, we tell you.

The main things we look at are:

1. Licensing and ownership: which licence a casino states, whether we can verify it, and whether the operating company is named.
2. Bonus terms: wagering requirements, game contribution, maximum bet while a bonus is active, expiry dates and cashout caps.
3. Payments: whether GBP accounts exist, which methods are stated for UK customers, fees and conversion costs.
4. Withdrawals: stated limits and processing times, and what verification is required.
5. Games and betting: the range of slots, live tables and sports markets, and named software providers.
6. Support and player protection: contact channels, complaints process and available limit tools.

We separate three kinds of information: what we have confirmed from official or primary sources, what a casino advertises, and what remains unresolved. Time-sensitive findings carry a date. Our latest fact-check date on this page is 29 September 2026. Offers and terms change often, so check the casino's own terms before you act.

How our rankings and ratings work

The ratings you see are editorial scores. They are our own judgement, not customer-review scores, and should not be read as a guarantee of how a casino will treat you. Among the casinos currently featured are Betmica, Kikibet, Betninja, WinnerIsland, Zombillion, Smash Casino, Nightluck, CoinPoker, Rivo and Daytonaspin.

Headline offers are shown as advertised. They are marketing, not promises. Big percentages and large caps often come with high wagering requirements, and some offers are shown in euros or dollars, which means currency conversion may apply to a UK player. Read the terms beside any offer before you claim it.

How we are funded

We may earn a commission if you sign up to a casino through a link on this site. Commission does not buy position: it does not decide rankings, ratings or what we say about a casino's weaknesses. Every casino we feature has limitations, and we try to state them plainly. You never pay more by using our links. See our terms and conditions for more detail.

What we cannot tell you

• We cannot guarantee that any casino will pay out, or how quickly. Withdrawal experiences vary and may depend on verification.
• We cannot call any casino completely safe. Overseas licensing gives you different protection from UK licensing, not necessarily less or more in every respect.
• We cannot verify every payment method for every UK customer. Check availability in the cashier before depositing.
• Gambling is not a source of income and is not a solution to money problems. Only stake what you can afford to lose.

Corrections and contact

If you spot an out-of-date term, a factual error or a casino problem we should know about, please tell us through our contact page. We review corrections and update pages where the evidence supports it.

If gambling is affecting your life, free help is available from GamCare and through the tools on our responsible gambling page, including self-exclusion, deposit and loss limits and blocking software.
