About Us
Casino Not On Gamstop is an independent research site for adults in the UK who want to understand non GamStop casinos before they decide anything. We explain how these sites work, what their bonuses really require, how payments and withdrawals tend to run, and what protections you give up or keep. This page tells you who we write for, how we assess casinos, and where our money comes from.
What we do, and what we don't
We publish reviews, comparisons and plain-English guides. Our focus is casinos that are not part of GAMSTOP, the national self-exclusion scheme for licensed operators in Great Britain. Our current spotlight is credit card casinos not on GamStop, but the same questions apply to any site: who runs it, what licence it holds, and what happens when something goes wrong.
We do not run a casino, take deposits or handle your money. We are not a regulator and we cannot resolve disputes with an operator. Our job is to help you read the terms before you sign up. Our main list of non GamStop casinos is the best place to see the current selection.
Why the regulatory picture matters
Many readers arrive assuming a casino that accepts British players is authorised to serve them. That is not the same thing. A site licensed by the UK Gambling Commission must follow Great Britain's rules, including participation in GAMSTOP. A site licensed elsewhere, often in an overseas jurisdiction such as Curaçao, follows different rules and offers different routes for complaints.
That has practical consequences. Overseas-licensed sites may not honour a GAMSTOP registration, and you may have fewer options if a withdrawal dispute arises. We say this plainly in our reviews rather than treating it as fine print.
How we research casinos
We have no testing evidence to offer, and we don't claim to have deposited, played or withdrawn at any site. Our reviews rest on desk research: reading each casino's published terms, licence statements, payment pages and bonus conditions, and checking them against what the site advertises. We treat these as three separate categories:
- Confirmed information: facts we could verify from a licence register, official terms or another checkable source.
- Casino advertising: claims made by the operator, which we label as claims.
- Open questions: anything we couldn't resolve, which we say we couldn't resolve.
Time-sensitive details such as bonus terms and payment availability change often. Where we date a finding, the date is the day we checked it. Our most recent fact-check for this page is 29 September 2026. Always read the operator's current terms before you commit.
What we look at in every review
| Area | What we check |
|---|---|
| Licensing and ownership | Which regulator is named, who operates the brand, and whether the details can be verified |
| Bonuses | Wagering requirements, game contribution, maximum bet while wagering, expiry dates and cashout caps |
| Payments | GBP accounts, minimum deposits, card, bank transfer, e-wallet and crypto availability, fees and currency conversion |
| Withdrawals | Stated processing times, limits, and identity and source-of-funds checks |
| Games and betting | Slots, live dealer, table games, sportsbook coverage and software providers |
| Support and complaints | Contact channels, complaint procedures and safer gambling tools |
We don't assume a payment method works for British customers. If a casino lists a method, we note that availability should be confirmed at the cashier before you rely on it.
How the rankings work
Each casino carries an editorial rating out of 10. It is our own assessment, not an average of customer reviews and not a measure of your likely results. At the time of writing, the top of our list is Betmica (10.0), followed by Kikibet and Betninja (both 9.9), then WinnerIsland and Zombillion (both 9.7).
Headline offers, such as Betmica's welcome offer of 570% up to £5,700 plus 270 free spins, are the operator's advertising. Big percentages usually come with wagering requirements, time limits and caps on winnings. Some offers are quoted in euros or dollars, which means you may face currency conversion unless the site supports a GBP account. We say so where it applies.
How we make money, and what it doesn't decide
We may earn a commission if you follow a link and sign up with a casino we feature. That is how the site is funded. Commission does not buy a place in our rankings, and an operator cannot pay for a better rating or for a weakness to be left out. Every review should include at least one genuine drawback, including for the casino at number one.
Honest limits of what we can offer
- We cannot guarantee that any casino will pay out, or that a withdrawal will be trouble-free.
- We don't describe any casino as completely safe.
- Gambling is not a source of income and is never a solution to money worries.
- Information can go out of date between checks.
Who this site is for
You must be 18 or over to gamble. We write for adults who already know they want to compare options, and for those still working out how licensing, wagering rules or KYC checks affect them. If you self-excluded through GAMSTOP because gambling was causing you harm, think carefully before looking at sites outside the scheme. Our responsible gambling page covers deposit and loss limits, self-exclusion, blocking software and support from GamCare. GamCare's helpline is free and confidential.
Contact and corrections
If you spot an error, or a casino's terms have changed, tell us through the contact page. Our terms and conditions set out how you may use this site. We correct factual mistakes when we can verify them.
