About Us

Slots Not On Gamstop is an independent research site for adults in the UK who want to understand non GamStop casinos before deciding whether to use one. This page explains who we write for, how we assess operators, how we earn money and where our knowledge stops.

What this site does

We publish reviews and guides on casinos that operate outside the GamStop scheme. We cover bonuses, wagering requirements, payments, withdrawals, games, sports betting and the protections that apply, or do not apply, to British customers. Our aim is to help you read an offer's terms properly. We do not aim to push you towards signing up.

Many readers arrive knowing little about licensing or wagering rules. We explain those terms in plain English and assume nothing. Our main comparison is on our non GamStop casinos list.

Commercial disclosure

The publisher supplies the casino selections and top lists. We may earn commission if you join an operator through a link on this site. Commission does not decide ratings or rank order. Our commercial relationships do not change how we describe a casino's drawbacks. You can read the wider rules in our terms and conditions.

How we assess casinos

We have not tested these casinos ourselves. We do not claim to have deposited, played or withdrawn money. Our reviews are based on desk research: the operator's published terms, licensing information it states, payment and support pages, and what can be checked against public sources. We date time-sensitive findings, and this page's facts were last checked on 29 September 2026.

We look at these factors:

• Licensing and ownership – which regulator or overseas licence the casino states, who operates it, and whether that can be verified.
• Bonus terms – wagering requirements, game contribution, maximum bet limits, expiry dates and cashout caps.
• Payments – GBP account availability, minimum deposits, fees, currency conversion and withdrawal limits.
• Verification and withdrawals – KYC, source-of-funds checks, stated processing times and how disputes are handled.
• Games and betting – slots, live dealer tables, sports betting and software providers.
• Player protection – deposit and loss limits, self-exclusion tools and complaints procedures.
• Support – the contact channels a casino says it offers.

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

How to read our ratings

Our scores are editorial ratings. They are our own assessment of the terms and features we could research. They are not customer-review scores, and they are not a promise of how any casino will treat you. The operators currently featured, in the publisher's order, are Betmica, Kikibet, Betninja, WinnerIsland, Zombillion, Smash Casino, Nightluck, CoinPoker, Rivo and Daytonaspin.

Advertised welcome offers are marketing. Betmica's headline is 570% up to £5,700 plus 270 free spins, for example. The wagering requirement, maximum stake, expiry and cashout limit decide whether an offer is worth taking, so read them before you accept any bonus. Several of these offers are stated in euros or dollars, so check your account currency and conversion costs.

What non GamStop means for you

GamStop is the national self-exclusion scheme for licensed gambling in Great Britain. Casinos licensed by the UK Gambling Commission must take part. Casinos not on GamStop generally hold overseas licences instead. That means a UK Gambling Commission licence does not cover them, and you may have fewer routes for complaints. A casino accepting British customers is not the same as being authorised to serve them under British rules.

If you have registered with GamStop, that was a decision to protect yourself. Using a site outside the scheme undermines that protection. If gambling is causing you harm, please read our responsible gambling page. GamCare offers free, confidential support on 0808 8020 133. You must be 18 or over to use any gambling site.

What we will not do

• Call any casino completely safe.
• Guarantee withdrawals or winnings.
• Present gambling as a source of income or a fix for money problems.
• Name competing publishers or invent facts we cannot support.

Corrections and contact

Terms change often. If you find a detail that is out of date or wrong, tell us through our contact page. We will review it and update the page where the evidence supports a change.
