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 bonuses, payments, withdrawals and protections work, and we compare the operators the publisher selects. This page sets out who we are, how we work and where the limits of our knowledge lie.

What this site does, and what it doesn't

Our subject is non GamStop casinos: online casinos and betting sites that are not part of GAMSTOP, the national self-exclusion scheme for licensed gambling in Great Britain. We cover slots, live dealer games, blackjack, roulette, baccarat, sports betting and esports betting, along with the terms that sit behind them.

We are a guide, not an operator. We don't run casinos, take bets or hold player funds. No author is named on this page because none has been supplied, and we won't invent credentials to make the site sound more authoritative.

Why we write about casinos outside GAMSTOP

Many readers arrive with a simple question: what actually differs when a casino is not on GAMSTOP? In short, quite a lot. Sites licensed by the UK Gambling Commission must follow British rules on advertising, affordability, complaints and GAMSTOP participation. Sites holding an overseas gambling licence, often from Curaçao, answer to a different regulator, and that regulator's protections and dispute routes are generally weaker and harder to use from the UK.

Accepting British customers is not the same as being authorised to serve them under British law. We try to make that distinction clear in every review, because it affects what you can rely on if something goes wrong.

If you have self-excluded, or are worried about your gambling, please read our responsible gambling guide before anything else. GAMSTOP, GamCare and blocking software exist to help, and we don't encourage anyone to bypass a self-exclusion they chose.

How we assess casinos

Our ratings come from desk research: reading the operators' published terms, checking licensing claims against what the operator states, and comparing features side by side. We have no testing evidence to offer, and we don't claim to have deposited, played or withdrawn at any casino. Where we can't confirm something, we say so.

The factors we look at are:

• Licensing and ownership – which regulator is named, whether the operator shows who owns the brand, and what that means for UK players.
• Bonus terms – wagering requirements, game contribution, maximum bet limits, expiry dates and cashout caps, not just the headline figure.
• Payments – minimum deposits, GBP account availability, debit cards, bank transfers, e-wallets, cryptocurrency, fees and currency conversion.
• Withdrawals – stated processing times, limits, and identity or source-of-funds checks.
• Games and betting – slots, jackpots, live dealer tables, software providers, and the sportsbook where there is one.
• Support and complaints – contact channels and how disputes are handled.
• Player controls – deposit and loss limits, self-exclusion tools and cooling-off options.

Stated processing times and advertised offers are what the casino says, not what we have measured. Editorial ratings are our own scores on a ten-point scale. They are not customer-review scores.

The casinos we feature

The publisher supplies our casino selections and top lists. Currently the ranking features Betmica, Kikibet, Betninja, WinnerIsland, Zombillion, Smash Casino, Nightluck, CoinPoker, Rivo and Daytonaspin. Our main non GamStop casinos comparison shows the current order, ratings and offers.

A few things to keep in mind when you read those offers:

• Headline bonuses are advertising. Percentages and totals can look large, but wagering requirements, maximum bets, expiry dates and withdrawal caps decide what a bonus is worth.
• Some offers are shown in euros or dollars. That means currency conversion, and possibly fees, if you fund a GBP account. Check what currency the account is held in.
• Payment methods, including PayPal and cryptocurrency, vary by operator and by country. Always check availability for British customers on the casino's own cashier page rather than assuming.

How we're funded and how we stay independent

We may earn a commission if you sign up with an operator through a link on this site. That is how the site is paid for. Commission does not buy position: it doesn't change a rating or a ranking, and no operator can pay to be described more favourably. We also aim to include at least one real drawback for every casino we recommend, including the top-ranked ones.

Our full terms and conditions explain how you may use the site.

Keeping information accurate

Bonus terms, payment options and licensing details change without warning. Each page shows an updated date, and our latest fact-check for this site was carried out on 29 September 2026. Treat anything time-sensitive as a starting point and confirm it with the casino before you deposit. If you find something out of date or wrong, please tell us through the contact page.

Who this site is for

This site is for adults aged 18 and over. Gambling is not a way to earn income or solve money problems, and no casino is completely safe or able to guarantee withdrawals or winnings. Only stake what you can afford to lose, set deposit and loss limits, and step away if it stops being enjoyable. Free, confidential help is available from GamCare through its National Gambling Helpline on 0808 8020 133.
