About Us

Who We Are

Casinos Not On Gamstop is an independent comparison and review site based in Great Britain. We research, assess and rank online casinos that operate outside the GamStop self-exclusion scheme, so that readers can make informed decisions about where to play. We do not operate any casino or gambling service ourselves — every site listed on these pages is a third-party operator, and our role is solely to provide clear, factual information about them.

Our editorial team reviews each operator against a consistent set of criteria: game range, bonus terms, payment options, platform quality and customer support. That process is described in full below.

Why This Site Exists

GamStop is the UK's voluntary self-exclusion register. Players who sign up to it are blocked from gambling with UKGC-licensed operators for a fixed period of their choosing. Some of those players later want to explore alternatives — casinos licensed in other jurisdictions that are legally accessible to adults in Great Britain, even though they fall outside GamStop's reach.

There is no shortage of such sites, but finding reliable, up-to-date information about them is harder than it should be. Casinos Not On Gamstop exists to fill that gap: a single, consistently maintained resource where readers can compare non-GamStop options side by side, understand the differences between them, and read honest assessments that include drawbacks as well as strengths.

We cover casinos that hold licences from recognised international regulators — such as those issued in Curaçao, Malta or Gibraltar — and we are transparent about what those licences do and do not guarantee for a UK player. For a full breakdown of how non-GamStop operators differ from UKGC-licensed ones, see our main non-GamStop casinos guide.

Our Editorial Standards

Every casino reviewed on this site has been researched by our team. We have not deposited funds or played for real money at any of these properties — where we refer to game ranges, bonus mechanics or payment speeds, those details come from reviewing the operators' own published terms, verifying bonus conditions at source, and monitoring for changes over time. We update our pages when terms shift, and each page carries a last-verified date.

Our ratings reflect independent editorial judgement. They are not customer-review aggregates, and they are not purchased. The criteria we weight most heavily for non-GamStop casinos are:

• Licensing and accountability — the jurisdiction and the strength of the regulatory framework behind it
• Bonus terms — wagering requirements, time limits, eligible games and maximum cashout caps
• Payment flexibility — methods available in GBP, deposit and withdrawal limits, and realistic processing times
• Game quality and range — software providers, breadth of catalogue, live-dealer provision
• No-KYC or light-KYC processes — which operators allow play before identity checks, and at what thresholds checks are triggered
• Support accessibility — live chat availability, response quality and language

Commercial relationships do not determine rank order. Some of the operators on this site pay us a commission when a reader signs up. That arrangement funds the site, but it has no bearing on where a casino is placed in our rankings — a lower-paying partner can and does outrank a higher-paying one where the editorial evidence supports it.

Affiliate Disclosure

Casinos Not On Gamstop earns revenue through affiliate arrangements with the operators featured on this site. When a reader follows a link from this site and registers or deposits at a casino, we may receive a commission from that operator at no extra cost to the reader. This is standard practice for independent comparison sites, and it is how we fund the research, writing and maintenance that keep this resource accurate. It does not influence our editorial conclusions — our assessments of strengths, weaknesses and rank positions are made independently of any commercial arrangement.

The Casinos We Cover

Our current ranked list includes ten operators we have researched and found suitable to feature. The top-rated options as of our most recent review cycle are summarised below.

Smash Casino — Rated 9.9

Smash Casino holds the top position on our list because it consistently performs well across the criteria that matter most to players seeking a non-GamStop experience: a broad game library, a transparent bonus structure and reliable payment processing. Its headline welcome offer — a 600% match up to €10,000 on slots — is one of the largest on our list by headline figure, though players should read the full wagering terms before committing, as high-percentage bonuses typically carry correspondingly demanding conditions. One genuine limitation: the €10,000 cap is denominated in euros, which means GBP deposits are subject to conversion and the effective value will shift with exchange rates.

Betninja — Rated 9.7

Betninja earns its second-place ranking in part because its welcome offer is straightforward by the standards of this market: £1,000 in bonus funds plus 100 free spins, with the bonus expressed in sterling rather than euros — a practical advantage for UK players who want to know exactly what they are claiming. Betninja also offers a sports betting product alongside its casino, which makes it one of the more versatile options for readers who want both in one account. The limitation worth noting is that the combined casino-and-sportsbook model can mean each vertical receives slightly less depth than a dedicated specialist.

WinnerIsland — Rated 9.6

WinnerIsland takes third place and is particularly strong on the live-dealer side of its catalogue, which distinguishes it from some of the slots-heavy operators lower in the list. Its welcome offer — up to €1,000 plus 100 free spins — is positioned at the more accessible end of the bonus scale, which tends to mean more achievable wagering requirements. The drawback is that its payment method range is narrower than some competitors, so players who rely on specific e-wallets or crypto options should verify availability before signing up.

A Note on the Remaining Operators

Zombillion, Gambiva, Kingdom Casino, Nightluck, Daytonaspin, Mad Casino and Wildzy all feature in our full ranked comparison. Each has been assessed against the same criteria; their positions reflect our current editorial view.

Responsible Gambling

This site is intended for adults aged 18 and over. If you are currently registered with GamStop and your exclusion period is still active, that exclusion was put in place for a reason you chose. We do not encourage anyone to circumvent a self-exclusion commitment they are not ready to end. If you have concerns about your relationship with gambling, our responsible gambling page lists organisations that can help, including free confidential support services available in the UK.

For players who do choose to engage with non-GamStop casinos, all of the operators on our list offer their own responsible gambling tools — deposit limits, session limits, self-exclusion at the operator level and cooling-off periods. These tools exist independently of GamStop and are worth using regardless of your history with the scheme.

Keeping Information Current

Bonus terms change. Operators enter and exit markets. Payment methods are added and removed. We review our rankings on a rolling basis and update individual pages when material changes occur. Each page displays its last-verified date so you can see how recently the information was checked. If you spot something that looks out of date, use our contact page to let us know and we will prioritise a review.

How to Use This Site

1. Start with the main rankings page for a full overview of all rated operators.
2. Use the comparison criteria — bonus terms, payment methods, game range — to shortlist the casinos that fit your preferences.
3. Read the individual write-up for each shortlisted casino, paying particular attention to the limitations noted.
4. Before registering, visit the casino's own site and verify the current bonus terms directly — offers change, and what you see at the casino takes precedence over any summary here.
5. Set your own deposit and session limits from the outset, using whatever tools the operator provides.

Our role is to narrow the field and surface the most relevant information. The final decision rests with you, and it should always be made on the basis of the operator's current, published terms.
