About Us

Sites Not on GamStop exists because GamStop isn't the only route available to UK players, and a lot of the information out there about the alternative isn't written by anyone who's actually looked closely at the sites in question. We built aviss.co.uk to go through non GamStop casinos properly - checking their licensing, their game libraries, their payment options and their bonus terms - so that readers can make an informed choice rather than gambling on a search result.

Why This Site Exists

GamStop is a UK self-exclusion scheme that blocks a person from using casinos and betting sites licensed by the UK Gambling Commission. It's a useful tool for players who want that barrier in place. But it doesn't cover every operator - plenty of established, internationally licensed casinos sit outside the UKGC's remit entirely and were never part of the GamStop system to begin with. These sites operate under licences from jurisdictions such as Curaçao, and they're used every day by adults across the UK who prefer a wider range of bonuses, payment methods and games than the domestic market typically offers. We don't view this as a loophole or a workaround - it's simply a different, legally operating part of the online gambling market, and our job is to cover it honestly.

What We Actually Do

Every casino that appears on aviss.co.uk has been researched against the same core criteria before it's ranked. We look at:

• Licensing and operator background - who runs the site, where it's licensed, and how long it's been trading.
• Game selection - the spread of slots, table games and live-dealer options, and which software providers supply them.
• Payment methods - what's available for UK players, including card payments, e-wallets and increasingly crypto options like Paysafe or CoinPoker-style wallets, plus the deposit and withdrawal limits attached.
• Bonus terms - not just the headline percentage, but the wagering requirements, maximum bet limits and expiry windows that come with it.
• Customer support and site reliability - how easy it is to get help and how the platform performs on mobile.

This process feeds directly into the editorial ratings shown on our non GamStop casinos comparison page, where operators like Betmica, Kikibet and Betninja are ranked side by side. A rating of 10.0 versus 9.6 reflects genuine differences in these categories, not a rounding error - and every write-up we publish includes at least one limitation alongside the strengths, because no casino is flawless.

How We Rate and Rank

Our rankings are built from research, not from how much a casino spends with us. Commercial relationships with some operators help fund the site - that's how independent comparison sites typically stay running - but paying us doesn't move a casino up the list. Position is decided by the criteria above, checked and updated as offers, licences or terms change. Where a casino tightens its withdrawal limits or drops a promotion, we update the listing rather than leave stale information live.

Non GamStop Casinos vs UKGC-Licensed Sites

It's worth being clear-eyed about the difference. UKGC-licensed casinos operate under UK consumer protection rules, including mandatory GamStop integration. Non GamStop casinos, licensed elsewhere, sit outside that specific scheme but still operate under their own regulator's rules covering fair play, game testing and dispute resolution. What this means practically for a reader is that self-exclusion through GamStop won't stop access to these sites - which is exactly why some players choose them - but it also means the UK-specific consumer protections a GamStop-registered site offers don't apply in the same way. We set this out plainly wherever it's relevant, rather than glossing over it.

The Bigger Picture: Bonuses, Games and Betting

Beyond the slots and table games that headline most non GamStop casinos, several of the operators we cover - including sites like Nightluck, Rivo and Smash Casino - also run sportsbook sections alongside their casino products, covering football, horse racing and other major markets. This crossover between casino and betting sites not on GamStop is common in this part of the market, and we treat it as part of the same research process rather than a separate topic.

Who Writes and Checks This Content

Our content is put together by a small team focused specifically on the non-GamStop casino sector. We don't publish paid reviews dressed up as editorial, and we don't claim to have deposited or withdrawn money at every site we cover - our research is based on publicly available terms, licensing records and platform testing where possible, not simulated play. Facts are checked and dated so readers know how current a page is.

Responsible Use of This Information

Everything on aviss.co.uk is intended for adults aged 18 and over. If you've self-excluded via GamStop, that decision was presumably made for a reason, and we'd encourage anyone reconsidering their relationship with gambling to read our responsible gambling page before doing anything else. Non GamStop casinos are a legitimate part of the market, but they don't come with the same built-in exclusion tools - so any additional safeguards, such as deposit limits or self-set breaks, are down to the player to arrange directly with the operator.
