About Us
Non Gamstop Casinos is an independent research and comparison site covering casinos not on GamStop for readers in the UK. This page explains who produces the content, how the rankings are built, where the money comes from, and — just as importantly — what our reviews cannot tell you.
We are not a casino, a bookmaker or a payment provider. We do not take deposits, hold player funds or settle bets. We publish written research about offshore operators that accept British customers, so you can read the terms before you sign up rather than after.
What "not on GamStop" actually means, and why we cover it
GamStop is the free national self-exclusion scheme for online gambling operators licensed by the Gambling Commission to serve customers in Great Britain. Register with it, choose an exclusion period of six months, one year or five years, and licensed British sites must block you for that term. Sites that sit outside the Commission's remit — typically licensed in Curaçao or another overseas jurisdiction — are not connected to that database, which is the entire reason they are described as casinos not on GamStop.
That distinction carries real consequences. An overseas licence is not a UK Gambling Commission licence. Accepting British customers is not the same as being authorised to serve them. If a dispute arises, you are not covered by the Commission's complaints framework, and there is no UK route to an ombudsman decision. We cover these sites because people search for them and deserve accurate information, not because we think they are a safer or better option than the licensed British market.
If you joined GamStop because gambling was causing you harm, seeking out a site that cannot see your exclusion undermines the decision you made. GamCare runs the National Gambling Helpline on 0808 8020 133, free and open 24 hours a day, and blocking software such as Gamban or BetBlocker adds a barrier that self-exclusion alone does not. Our responsible gambling guidance sets out deposit limits, loss limits and self-exclusion tools in more detail.
How we make money
Non Gamstop Casinos earns revenue through affiliate arrangements. If you follow a link to an operator and open an account, we may receive a commission from that operator. You pay nothing extra, and the offer you see is the offer the casino publishes.
Commission does not buy a position in our lists. Rates are not a scoring criterion, our editorial team is not shown them when ordering a table, and an operator cannot commission a rewrite of a section it dislikes. Where a site has a weakness that matters — unclear ownership, a punitive wagering multiple, a low monthly withdrawal ceiling — we say so on the same page that carries its bonus. Where we have not been able to verify something, we say that too instead of filling the gap with the operator's own marketing.
How the ratings are put together
Our scores are editorial judgements on a 10-point scale. They are not customer satisfaction scores, not aggregated user reviews, and not the result of us depositing money and playing. There is no test-account programme behind this site. Everything we publish comes from reading published terms and conditions, checking licence registers and ownership disclosures where they are available, comparing payment pages, and re-checking claims on a schedule. Findings on this page were last verified on 23 September 2026 by Geraint Howell.
| What we check | What we look for | Why it decides the score |
|---|---|---|
| Licence and ownership | Named licensing jurisdiction, licence number, the company behind the brand and any sister sites | An anonymous operator gives you nobody to escalate to |
| Bonus terms | Wagering multiple, whether it applies to bonus or deposit plus bonus, expiry, maximum bet while wagering, cashout cap | A headline percentage means little until you know the conditions |
| Payments | GBP account support, debit cards, bank transfer, e-wallets, crypto, fees and conversion | Currency conversion quietly reduces what you deposit and what you get back |
| Withdrawals | Stated processing times, daily, weekly and monthly limits, KYC and source-of-funds triggers | Withdrawal limits are the most common source of complaints |
| Games and providers | Slot range, live dealer rooms, table games, named studios, published RTP information | Recognised studios are independently tested; unnamed ones are not |
| Support and complaints | Live chat and email availability, published complaints procedure, any external dispute body | Determines what happens when something goes wrong |
Three operators, and what our research shows
The cards above are ordered by editorial rating. Below is what sits behind the top of that list, including the parts an advert leaves out. Offers change without notice — always read the current terms on the operator's own site before depositing.
Betmica — rated 10.0
Betmica leads our table on the breadth of its headline package rather than on any single feature: a welcome offer of 570% up to £5,700 plus 270 free spins, quoted in pounds, which matters because a sterling-denominated bonus avoids the conversion loss that bites on euro-priced packages. It sits first because the offer is stated clearly in GBP and the site presents a conventional slots-led lobby with live dealer tables alongside.
What the figure does not tell you: a percentage that large is calculated on a deposit, so reaching anything near £5,700 in bonus funds requires a four-figure stake of your own. Wagering requirements, maximum bet caps while a bonus is active and any cap on converted winnings apply, and those terms decide whether the offer is worth taking at all. Limitation: as with every site on this page, Betmica operates outside UK Gambling Commission oversight, so you have no Commission-backed complaints route and no GamStop protection.
Kikibet — rated 9.9
Kikibet earns its place for a comparatively restrained structure: 350% up to £5,555 and 300 free spins. The multiplier is lower than Betmica's, which in practice usually means a more achievable path through the wagering, and the free-spin count is higher. It is the option to look at if you want a sizeable package without the largest headline number on the page.
Limitation: free spins are frequently restricted to nominated titles, drip-fed across several days and carry their own wagering on winnings. Check the spin value and the expiry window before you treat 300 spins as 300 chances. Verification requirements and withdrawal ceilings should be read before your first deposit, not at your first cashout.
Betninja — rated 9.9
Betninja is the simplest proposition in the top group: £1,000 bonus and 100 free spins for all new players, a flat sterling figure rather than a percentage stack. For readers who find tiered packages hard to evaluate, a single number and a single spin allocation is easier to weigh against its wagering multiple.
Limitation: a smaller headline can still carry a heavy multiple, and a modest bonus with 50x wagering is worse value than a larger one at 25x. "All new players" is also subject to country eligibility and the usual one-account, one-household rule. Confirm both before you rely on it.

Where an offer is quoted in euros or dollars, expect currency conversion on deposits and withdrawals unless the operator confirms a GBP account. Conversion spreads and card issuer fees both apply, and neither is usually shown on the promotions page. Fuller assessments sit on our reviews of top-rated non GamStop casinos.
The money side we always check
Costs at an offshore casino are rarely a single advertised price. They accumulate across four points:
- Minimum deposit — commonly £10 to £20, but bonus qualification thresholds are often higher than the site minimum. Depositing the minimum can leave you outside the offer.
- Deposit methods — debit cards, bank transfer, e-wallets and cryptocurrency are the usual set. UK debit cards are sometimes declined by the issuer on offshore gambling merchants; credit cards are prohibited for gambling in Great Britain. PayPal is rarely available at non GamStop sites and should never be assumed — check the cashier page, not a promotional banner.
- Withdrawals — processing times typically split into an operator review period and then the payment rail's own timing. E-wallets and crypto usually settle faster than bank transfer. Daily, weekly and monthly caps are common, and a large win can take months to release under a low monthly ceiling.
- Fees and conversion — some sites charge for withdrawals below a threshold or for a second cashout in a period. Currency conversion applies twice on a euro or dollar account: once in, once out.
Every operator will also run KYC identity verification, and many run source-of-funds checks on larger withdrawals. Providing documents early, rather than when a payout is pending, is the single most effective way to avoid a delay.
What these sites offer beyond slots
The lobbies we assess generally break into four parts: slot machines, including progressive jackpot titles; table games such as blackjack, roulette and baccarat in RNG form; live dealer rooms with human croupiers streamed in real time; and a mobile version of the lobby accessed through a browser. When we describe a game range we name only what the operator publishes. We do not quote catalogue totals we cannot verify, and we treat advertised RTP figures as the provider's published numbers rather than anything we have measured. Volatility descriptions are the studio's own classification.
Most of these brands also run a sportsbook alongside the casino, and it behaves differently from the slots side. Expect pre-match and in-play markets, accumulators, bet builders, cash-out and esports, with odds usually shown in decimal format — 2.50 rather than 6/4. Sports free bets carry their own terms, most often a minimum qualifying odds condition such as 1.80 or higher, and the stake is not returned with winnings. Where a shared wallet covers both products, casino bonus funds are frequently barred from sports markets, and wagering contribution rules differ between the two.
Who can use these sites, and what that means for you
You must be 18 or over. Overseas casinos set their own accepted-country lists, and a site accepting British sign-ups is a commercial decision on their part, not evidence of UK authorisation. The Gambling Commission licenses operators serving Great Britain; Northern Ireland has its own gambling legislation, so "UK" and "Great Britain" are not interchangeable when describing regulatory scope, and GamStop's mandatory reach is over Commission-licensed sites.
Practical obligations that follow for you as the customer: winnings from gambling are not taxed as income for UK individuals, but you are responsible for your own account security and for the accuracy of the details you give at verification. You have no Gambling Commission complaints route at an offshore site, so the operator's published complaints procedure and any named external dispute body are worth reading before you deposit. Gambling is entertainment with a built-in cost, never a way to make money or fix a financial problem.
Corrections, and getting in touch
Terms move faster than any review schedule. If an offer has changed, a payment method has been withdrawn or we have got something wrong, tell us and we will check it and update the page. Our contact page is the fastest route, and the terms of use set out the basis on which this content is published.
A reasonable way to use this site: start with the comparison of licensing and withdrawal limits rather than the bonus percentages, shortlist two or three operators whose terms you can live with, then read their full conditions on their own site before you commit anything. If reading this page has made you uneasy about your own gambling, the helpline number above is open right now.
