About Us

Non Gamstop Casinos was set up for one straightforward reason: readers who have self-excluded through GAMSTOP still ask sensible, practical questions about the wider market, and there was no independent site answering them properly. We built sheffieldchildrenshospital.org.uk to research and compare casinos operating outside the UK self-exclusion scheme, so visitors can make an informed choice rather than guessing which sites are worth their time.

What we actually do

We're a comparison and review resource, not an operator. We don't take bets, hold customer funds or run any of the casinos listed on this site. Our job is to research brands that accept UK players but sit outside GAMSTOP, check what they offer, and lay that information out clearly — welcome offers, game libraries, payment options and the practical details that decide whether a site is worth a look.

Our current list, from Non GamStop Casinos 2026 - Best Online Casinos UK, includes brands such as Betmica, Kikibet, Betninja, WinnerIsland and Zombillion, alongside others further down the table. We update it as new casinos not on GAMSTOP launch and as existing offers change.

How we rate and rank casinos

Every brand on this site is scored editorially, on a consistent set of factors:

• Welcome offer terms — the headline percentage or amount, plus the wagering requirements, minimum deposit and time limits attached to it
• Game range — the balance of slots, table games and live-dealer options available
• Payment methods — the deposit and withdrawal options offered, and how practical they are for UK players
• Licensing and operating jurisdiction — most sites in this space hold offshore licences, commonly from Curaçao, rather than a UK Gambling Commission licence
• Site usability — how the casino performs on mobile, how clear its terms are, and whether support is easy to reach

Commission from any casino we link to never affects where it sits in our rankings. A brand's position reflects our research against the criteria above, nothing else. Where we haven't been able to verify a detail — a specific withdrawal time or support hour, for example — we say so rather than guessing.

A short look at three brands we rank highly

Betmica tops our current list with a Welcome Offer of 570% up to £5,700 plus 270 free spins — one of the largest headline packages we've seen in this space. The scale of that offer is exactly why it sits at number one, but readers should treat any bonus this size as carrying correspondingly steep wagering requirements, which is worth checking before depositing.

Kikibet follows closely with 350% up to £5,555 and 300 free spins. It's a more moderate headline figure than Betmica's, which in our experience often means slightly more workable wagering conditions — though as with any offshore casino, the terms need reading in full rather than assumed.

Betninja rounds out our top three with a flat £1,000 bonus and 100 free spins for new players. The simplicity of a fixed-amount offer, rather than a percentage tied to deposit size, can make it easier to understand what you're actually getting, though it also means smaller depositors won't unlock the full bonus value in the same way a percentage match would deliver.

Further down the table, brands like WinnerIsland, Zombillion, Smash Casino, Nightluck, CoinPoker, Rivo and Daytonaspin all offer their own welcome packages and are covered in more detail on our main comparison page.

Where GAMSTOP fits into this

GAMSTOP is the UK's free self-exclusion scheme, letting individuals block themselves from gambling sites licensed by the UK Gambling Commission. Casinos not on GAMSTOP are typically licensed elsewhere — often in Curaçao — which means they aren't connected to the UK scheme and don't check against it. We report on how these sites operate; we don't advise anyone to bypass a self-exclusion decision, and we take no view on individual readers' circumstances. If self-exclusion was the right choice for you, our Responsible Gambling page has support resources worth reading alongside anything on this site.

What sits beside the casino offering

Most brands we cover don't stop at slots and table games. It's common for the same platforms to run sportsbook sections alongside the casino — covering football, tennis, horse racing and similar markets — so readers researching betting sites not on GAMSTOP will often find it's the same operator wearing two hats rather than a separate product. We note this where it applies, but our focus and expertise stay with the casino side of the site.

Why our approach is worth trusting

We're independent of the casinos we review. Some links on this site are commercial, meaning we may earn a referral fee if a reader signs up through them — but that relationship never decides a ranking position or the tone of a review. We'd rather flag a genuine drawback than smooth it over, and every casino we cover comes with at least one limitation worth knowing before you commit any money.

Full terms covering how this site operates are set out in our Terms and Conditions.
