About Us
Slots Not On Gamstop is an independent research site for adults in the UK who want to understand casinos that operate outside GAMSTOP. We review the offers, explain the terms behind them and set out the risks, so you can decide with the facts in front of you. This page explains who we are, how we work, how we are funded and where our limits lie.
What we do and who we write for
Our readers are adults aged 18 and over, mostly in the UK, comparing online casinos and sportsbooks. Some know gambling terms well. Many do not, so we explain wagering requirements, withdrawal limits and identity checks in plain English rather than assuming you know them.
Our coverage includes:
- Casino reviews and top lists, including sites that accept Paysafe-style prepaid payments, cards, e-wallets and cryptocurrency where the operator says so
- Guides to bonuses: welcome bonuses, deposit bonuses, free spins, no-deposit bonuses, cashback and loyalty rewards
- Explanations of games: slots, progressive jackpots, live dealer games, blackjack, roulette and baccarat
- Sports betting guides, including esports, pre-match and in-play betting, accumulators, bet builders and cash-out
- Payments, withdrawals, verification checks and complaints procedures
Our main list is on non GamStop casinos for UK players. If you want the detail behind a term, start there and follow the guides.
What "not on GAMSTOP" actually means
GAMSTOP is the free national self-exclusion service. Casinos licensed by the UK Gambling Commission (UKGC) to serve customers in Great Britain must check it. A casino not on GAMSTOP is not part of that scheme, and it usually holds an overseas licence, often from Curaçao or a similar jurisdiction.
Three points matter here:
- Accepting British players is not the same as being authorised to serve them. A site can take UK sign-ups without holding a UKGC licence.
- Protections differ. UKGC rules on advertising, affordability checks, complaints and dispute resolution may not apply. An overseas licence gives a different, and often weaker, route for complaints.
- Your GAMSTOP registration will not cover these sites. If you have excluded yourself because gambling was causing you harm, these casinos are not a safe place to return to.
We report on these operators. We do not say they are safe, and we do not encourage anyone who has self-excluded to look for a way round it.
How we research and rank casinos
We have not deposited, played or withdrawn at these casinos, and we do not claim to have. Our reviews rest on desk research: the operator's published terms, its stated licensing and ownership details, payment and bonus pages, and what we can verify from public sources. Facts were last checked on 29 September 2026. Offers change often, so confirm the current terms on the casino's own site.
When we assess a casino we look at:
- Licensing and ownership: which licence is stated, whether the operator names the company behind the site, and whether that can be verified
- Bonus terms: wagering requirements, game contribution, maximum bet while a bonus is active, expiry dates and cashout caps
- Payments: minimum deposits, GBP account availability, fees, currency conversion and which methods are stated for UK customers
- Withdrawals: stated processing times, limits, and identity and source-of-funds checks
- Games and betting: the mix of slots, live dealer tables and sportsbook, and the software providers named
- Player tools and support: deposit and loss limits, self-exclusion, contact channels and complaints procedures
We separate three kinds of information: what we have confirmed, what the casino advertises, and what remains unresolved. Where we cannot verify something, we say so.
How the editorial ratings work
The ratings you see beside each casino are editorial scores. They are our assessment of the terms and features we could review. They are not customer-review scores and not a promise of how your experience will go. Our top-ranked options at the time of writing are Betmica, Kikibet and Betninja, followed by WinnerIsland, Zombillion, Smash Casino, Nightluck, CoinPoker, Rivo and Daytonaspin.
No rating is a claim of safety. Even a top-rated casino has drawbacks, and our write-ups say what they are.
How we are funded
We may earn a commission if you click a link and sign up at a casino we list. Commission does not buy position. Ranking is based on our assessment of terms and features, and a casino cannot pay for a higher place or for a softer review.
Advertised bonuses are the casino's own offers, for example percentage matches with free spins. They carry conditions such as wagering, expiry and cashout limits. Nothing on this site guarantees value, winnings or a withdrawal. Read the full bonus terms before you accept any offer.
Money, games and betting: what we cover and why
Most casinos we review run several product lines from one account:
| Area | What we look at |
|---|---|
| Casino games | Slots (including RTP and volatility), progressive jackpots, live dealer games, blackjack, roulette, baccarat, mobile play |
| Sportsbook | Pre-match and in-play markets, esports, accumulators, bet builders, cash-out, sports free bets and minimum qualifying odds (shown as decimal odds) |
| Payments | Debit cards, bank transfers, e-wallets, PayPal availability, cryptocurrency, fees and currency conversion |
| Account rules | Verification, withdrawal limits, disputes, shared casino and sportsbook wallets |
We do not assume a payment method works for UK customers. We check what each operator states and tell you to confirm it before depositing. Illustrative amounts on this site are in pounds sterling.
Legal standing and eligibility
You must be 18 or over to gamble. In Great Britain, operators offering gambling to customers must hold a UKGC licence. Overseas-licensed sites that target British players sit outside that system, and the rules differ in Northern Ireland and the wider UK. If you use them, you carry more of the risk yourself. Winnings are currently not taxed for UK players, but check the position for your own circumstances.
Expect identity verification and, on larger withdrawals, source-of-funds checks. Read the terms and conditions that apply to this site as well.
Safer gambling
Gambling is entertainment with a cost. It is not a source of income or a fix for money problems. Use deposit and loss limits, take breaks, and stop if it stops being fun. Blocking software can help you keep away from gambling sites. Our responsible gambling page covers tools and support in more detail.
If you are worried about your gambling, GamCare runs a free, confidential helpline on 0808 8020 133, and its live chat is also available. You can register with GAMSTOP for exclusion periods of six months, one year or five years.
Corrections and contact
Terms change and mistakes happen. If you spot outdated information or want to raise a question about a review, use our contact page. We will check the claim and update the page where needed.
