About Us

Sites Not On Gamstop is an independent research site for adults in the UK who want to understand casinos not on GamStop before deciding anything. This page explains who writes the reviews, how the ranked list is put together, how we make money, and where our knowledge stops.

Our guides are written by Peter Pritchard. Facts on this page were last checked on 29 September 2026.

What we do and who it is for

We publish reviews and guides about casinos that operate outside the GamStop scheme. We cover bonuses, wagering requirements, payments, withdrawals, games, sports betting and customer support. Our aim is to help you see the terms and restrictions clearly, not to push you towards a sign-up.

The site is for people aged 18 or over. You do not need prior knowledge. Where a term such as wagering, KYC or source-of-funds checks matters, we explain it plainly.

Our main comparison is on our reviewed list of non GamStop casinos.

Commercial disclosure

We may earn a commission if you register with a casino through a link on this site. That commission does not decide rankings, and operators cannot pay for a higher position. It does mean we have a financial interest in clicks, so please read the terms of any offer yourself. Our terms and conditions set out how the site may be used.

How we research and rank casinos

The publisher supplies the casino selections and top list. Our role is to review them and explain what the published terms mean. We have not deposited, played or withdrawn money at these casinos, and we do not claim to have done so. Our work is desk research: reading the operator's published terms, checking what licensing information it displays, and comparing the advertised offers.

We look at:

• Bonus terms – wagering requirements, game contribution, maximum bet while wagering, expiry dates and cashout caps
• Payments – whether GBP accounts are offered, which deposit and withdrawal methods are listed, fees and currency conversion
• Withdrawals – stated limits, processing times and identity verification rules
• Games and betting – slots, live dealer tables, sports and esports markets
• Support and complaints – contact channels and how disputes are handled
• Player protection – limits, self-exclusion tools and links to help

Editorial ratings are our own scores on these factors. They are not customer-review scores. Advertised withdrawal speeds are the casino's claims, not results we have measured.

What the ranking currently shows

The list is topped by Betmica, with an editorial rating of 10.0. Kikibet, Betninja and WinnerIsland follow at 9.9. Headline offers are marketing claims and always carry conditions. Take Betmica's advertised 570% up to £5,700 plus 270 free spins. The larger a bonus, the more you usually have to wager before you can withdraw, and there may be a cap on winnings from it. Read the terms first.

Some listed offers are quoted in euros or dollars, for example WinnerIsland, Smash Casino, Nightluck, Rivo and CoinPoker. That raises the question of whether a GBP account is available and what conversion charges apply. Check this before you deposit.

What "not on GamStop" means, and what we cannot promise

GamStop is the free self-exclusion service that UK Gambling Commission licensed operators serving Great Britain must use. A casino that is not on GamStop is not part of that scheme. Many hold an overseas licence instead, such as one issued in Curaçao. Accepting British customers is not the same as being authorised by the UK Gambling Commission to serve them. Overseas licensing gives you different protections, and UK complaint routes may not apply.

We therefore never describe a casino as completely safe and never guarantee withdrawals or winnings. Gambling is entertainment with a built-in house edge. It is not income and not a way to fix money problems. If you have joined GamStop, choosing a casino outside it undermines a decision you made to protect yourself. Please think hard about that.

Where we separate fact from advertising

• Confirmed – details we could verify against the operator's published terms or a regulator's register
• Advertised – offers and speed claims made by the casino
• Unresolved – anything we could not check, which we say so rather than guess

Terms change often. If something on the site looks out of date, tell us via our contact page.
