About Us
Non Gamstop Casinos is an independent research and comparison site covering casinos not on GamStop — online casino and betting sites that hold overseas licences and therefore sit outside the UK Gambling Commission's self-exclusion scheme. This page explains who produces that research, how the rankings are built, how we earn money, and what our scores can and cannot tell you before you register anywhere.
We are not an operator. We do not take deposits, hold player funds or run games. We publish reviews, comparison tables and explainer guides so that a reader can work out what an offer actually costs them once the wagering requirement, the maximum bonus bet and the cashout cap are taken into account.
Why a site about non-UK casinos exists at all
GamStop is the free self-exclusion scheme every operator licensed by the UK Gambling Commission must integrate with. Register, choose a six-month, one-year or five-year exclusion period, and every GB-licensed site is required to block you for that term. A casino not on GamStop is one licensed elsewhere — Curaçao is the most common jurisdiction, with Anjouan, Costa Rica and Malta also appearing — which means the scheme's block does not reach it.
That distinction matters more than the marketing around it suggests. Accepting British customers is not the same as being authorised to serve them. An overseas licence does not bring UK consumer protections with it: no UK Gambling Commission complaints route, no obligation to follow GB affordability and advertising rules, and no automatic access to the alternative dispute resolution bodies a GB-licensed site must use. Our job is to describe that gap plainly rather than paper over it.
If you are currently self-excluded through GamStop, the honest advice is that this category is not for you, and our responsible gambling guidance sets out the blocking tools and support services that are.
Who writes the research
Editorial work on Non Gamstop Casinos is produced by Non Gamstop Casinos's consumer editor, Colin Ashworth, with fact-checking passes against operator terms and licence registers. Findings on this site are dated so you can see how fresh they are; this page was last fact-checked on 23 September 2026. Bonus terms, payment options and withdrawal limits at offshore casinos change without notice, so a dated finding is a snapshot, not a permanent guarantee.
We do not claim to have played at, deposited with or withdrawn from the sites we cover. Nobody on this site presents advertised payout speeds as measured results. Where we say a site processes e-wallet withdrawals quickly, that is the operator's published claim, labelled as such.
How we assess a casino not on GamStop
Every site is reviewed against the same criteria, weighted towards the things that decide whether a UK reader gets a usable experience or a frustrating one.
- Licence and ownership. Which regulator, which licence number, which company is named in the terms, and whether that information is published at all. Missing ownership details count against a site.
- Bonus terms, not bonus headlines. Wagering multiple, whether it applies to bonus only or deposit plus bonus, game contribution percentages, maximum bet while a bonus is active, expiry window and any cap on what you can cash out from bonus play.
- Money in and out. Whether GBP accounts are offered, which deposit methods are genuinely available to British customers, minimum deposits, fees, currency conversion, stated withdrawal processing times and weekly or monthly withdrawal limits.
- Verification. When KYC is triggered, what documents are requested, and whether source-of-funds checks are described in the terms.
- Games and providers. Breadth of slots, live dealer tables, progressive jackpots, published RTP information and which studios supply the content.
- Sportsbook, where one exists. Pre-match and in-play markets, esports coverage, accumulators, bet builders, cash-out and whether the casino and sportsbook share one wallet.
- Support and complaints. Contact channels, stated hours, and what the terms say about escalating a dispute.
- Player protection tools. Deposit limits, loss limits, time-outs and site-level self-exclusion, none of which replace GamStop.
How we pay for this
Non Gamstop Casinos earns commission when a reader follows a link to an operator and opens an account. That is how the site funds its research. Commercial relationships do not buy ranking positions, do not raise editorial ratings and do not remove criticism — every operator featured here carries at least one stated drawback, including the top-ranked one. Ratings on this site are our editorial judgement, not customer-review averages, and they are not a prediction of how any individual account will be handled.
Three of the sites we rank, and what we flag about them
Betmica — rated 10.0
Betmica leads our table because its published offer is aimed squarely at slots players who want a long bonus runway: a welcome offer of 570% up to £5,700 plus 270 free spins, advertised in pounds, which spares UK readers the conversion friction of a euro-only account. For this category, a GBP-denominated headline is a practical advantage rather than a cosmetic one.
The limitation is the one that applies to any percentage offer of this size: a 570% match is only worth what the wagering requirement, maximum bonus bet and cashout cap allow you to withdraw, and those terms sit in the bonus rules rather than the banner. Read the qualifying deposit, the expiry window and the game contribution table before you treat £5,700 as a meaningful figure. Betmica also operates under an overseas licence, so no UK Gambling Commission complaints route applies.
Kikibet — rated 9.9
Kikibet is here for a more moderate structure: 350% up to £5,555 with 300 free spins, again quoted in sterling. The lower multiplier usually means a shorter path to clearing a bonus than the headline-chasing packages, and the free spin count is generous relative to the match.
Against that, free spins almost always carry their own wagering and a cap on winnings converted from spins, and spins are typically locked to nominated slots at a fixed stake value. Check which titles qualify and what the per-spin value is; 300 spins at a low fixed stake is a different proposition from 300 spins at your chosen bet size.
Betninja — rated 9.9
Betninja takes a flat-amount approach — a £1,000 bonus and 100 free spins for all new players — which is easier to reason about than a percentage ladder. Readers who dislike working out what deposit unlocks what fraction of a headline figure tend to find fixed-cash offers more transparent.
The trade-off is ceiling: £1,000 is modest next to the packages above it, so higher-stakes players will exhaust it sooner. As with every site in this category, verification is the point at which problems surface, so expect ID and address documents before a first withdrawal and be prepared for source-of-funds questions on larger balances.
The wider table at a glance

All offers are new-player promotions subject to minimum deposit, wagering, maximum bonus bet and expiry terms published by each operator. Euro and dollar figures convert at the rate applied by your bank or the casino, so the sterling value you see will differ from the headline. Full breakdowns sit on our reviewed list of non GamStop casinos.
What it costs to take part, and how money moves
There is no charge for using Non Gamstop Casinos. The costs sit with the casinos, and they are worth understanding before you register.
- Minimum deposits at offshore sites commonly start in the £10–£20 range, though crypto-first sites sometimes set theirs by coin value instead.
- Debit cards are the usual UK route. Credit cards are prohibited for gambling in Great Britain, and some overseas sites still list them — that is a red flag worth noting.
- Bank transfers are widely accepted for larger amounts but are the slowest option both ways.
- E-wallets vary site by site. PayPal is rare outside GB-licensed operators, so never assume it is available; check the cashier before depositing.
- Cryptocurrency appears frequently in this category. It can be fast, but the value of your balance moves with the market and chargeback protection does not exist.
- Fees and conversion. If the account is held in euros or dollars, you pay conversion on the way in and again on the way out, plus any card issuer charge.
On the way out, expect KYC before the first withdrawal is released, a stated processing window that runs from hours to several working days by method, and weekly or monthly withdrawal ceilings that can stretch a large win over weeks. Where a dispute arises, an overseas licensee's complaints procedure is the route available — there is no UK Gambling Commission adjudication behind it.
The products these operators run
Our coverage follows what these sites actually offer, which is broader than slots alone:
- Slots — the bulk of most libraries, spanning low-volatility titles with frequent small wins and high-volatility games with long dry spells, plus published RTP figures that are worth checking per game.
- Progressive jackpots — pooled prizes that typically require a qualifying stake and often contribute little or nothing towards wagering.
- Live dealer rooms — streamed blackjack, roulette and baccarat, usually contributing a reduced percentage to bonus wagering, sometimes none.
- Mobile play — browser-based in most cases, with game availability occasionally narrower than on desktop.
- Sports and esports betting — the adjacent product line at most of these brands, covering pre-match and in-play markets, accumulators, bet builders and cash-out, with free bets that carry minimum qualifying odds. Sportsbook wallets are sometimes shared with the casino and sometimes separate, which changes how a bonus behaves.
Who this site is for
Non Gamstop Casinos is written for adults aged 18 or over in the United Kingdom who are researching offshore casino sites and want the terms explained before they commit. It is not written for anyone currently self-excluded through GamStop, and it is not written for anyone treating gambling as a way to make money or fix a financial problem — it is neither.
If money or time spent gambling has stopped feeling like your choice, GamCare runs the National Gambling Helpline free on 0808 8020 133, 24 hours a day, and blocking software plus bank gambling blocks work independently of any operator's own tools. Our player protection page covers deposit limits, loss limits and exclusion periods in more detail.
Corrections, questions and disagreements
If a bonus term has changed, a payment method has been withdrawn or a review has gone stale, tell us and we will check it against the operator's current terms and re-date the page. Our contact page is the fastest route, and the terms of use set out what this site is and is not responsible for. We would rather publish a correction than defend a claim that no longer holds.
