About Us
Non Gamstop Casinos is an independent research and comparison site covering new casinos not on GamStop for adult readers in Great Britain. We are not a casino, we do not take deposits or bets, and we do not operate any of the brands listed on this site. What we publish is desk research: licence checks, terms and conditions read line by line, payment pages compared, and bonus offers converted into plain figures a reader can weigh up.
This page explains who the site is for, how we build our rankings, how we are paid, and — just as important — the things we cannot tell you. If you want the current list itself, start with our reviews of non GamStop casinos for UK players.
Why a site about casinos outside GamStop exists at all
GamStop is the free national self-exclusion scheme for Great Britain. Every operator licensed by the UK Gambling Commission to offer remote gambling to British customers must integrate with it, so once a person registers with GamStop they cannot open or use an account at any GB-licensed online casino or bookmaker for the period they chose: six months, one year or five years.
Casinos not on GamStop sit outside that system because they are not licensed by the UK Gambling Commission. They typically hold an overseas licence — Curaçao is the most common, with Anjouan, Malta and others also appearing — and are registered to companies based outside the UK. Accepting British customers is not the same thing as being authorised to serve them. That distinction runs through everything we publish.
Readers reach a page like this for different reasons: curiosity about a brand they have seen advertised, frustration with verification at a UK site, or an active GamStop registration. We will not pretend the last group does not exist, and we will not pretend the choice is a neutral one. If you registered with GamStop because gambling was causing you harm, playing at an overseas casino defeats the purpose of the exclusion. Our responsible gambling page sets out the blocking software, deposit limits and support services that actually help in that situation, including GamCare's National Gambling Helpline on 0808 8020 133, free and open 24 hours a day.
What we assess, and what each factor is worth
New casinos not on GamStop launch constantly, often reusing the same platform software and the same bonus templates. A new brand is not automatically a worse one — but it has no payout history, so we weight the checkable things more heavily than the promises.
- Licence and ownership — which regulator is named in the footer, whether the licence number resolves, and which company is stated as the operator. Where ownership is unclear, we say so rather than filling the gap.
- Bonus terms, not bonus headlines — wagering requirement and whether it applies to bonus only or deposit plus bonus, game contribution rates, maximum bet while wagering, expiry window, and any cap on what can be withdrawn from bonus winnings.
- Payments for British customers — whether GBP accounts are offered, which debit card, bank transfer, e-wallet and cryptocurrency options appear at the cashier, stated minimum deposits, and any conversion or processing fee.
- Withdrawals — stated processing times, daily, weekly and monthly limits, and how KYC identity verification and source-of-funds checks are described in the terms.
- Games and providers — the mix of slots, progressive jackpots, live dealer tables and RNG table games, and which software studios supply them.
- Sportsbook, where one exists — pre-match and in-play markets, esports coverage, accumulators, bet builders, cash-out, and whether casino and sportsbook share a wallet.
- Support and complaints — contact channels, stated hours, and what the terms say about escalating a dispute.
Our ratings are editorial scores produced by our own review team. They are not customer-review averages and they are not a measure of how likely you are to win. Time-sensitive findings carry the date they were checked; the fact-check date for this page is 26 September 2026.
How we are paid, and what that does not buy
Non Gamstop Casinos earns commission when a reader clicks through to a casino and opens an account. That is how the site is funded. Commercial relationships do not decide rank order, and no operator can pay to be rated higher, to have a drawback removed, or to be added to a list it did not otherwise qualify for. Every brand we recommend gets at least one stated limitation, including the one at the top.
What we cannot do is test. We have not deposited at these casinos, played their games or made withdrawals, and we will never describe a payout as verified from experience. Advertised withdrawal speeds are advertised speeds. Treat them as claims until your own first cashout proves otherwise.
Three of the brands we currently rank, and how we read them
The cards above show the full current order. Below is how three of the highest-rated entries look when the headline is set aside — chosen to show the method rather than to push a particular sign-up.
Betmica — the largest headline package we list, and the most terms to read
Betmica sits top on our editorial scoring at 10.0, largely because it combines a GBP-denominated welcome offer with a broad slot library and a live dealer section. The advertised offer is 570% up to £5,700 plus 270 free spins for new accounts, typically released in stages across the first deposits rather than in one lump. A package that size carries a proportionate wagering requirement, a per-spin maximum bet while the bonus is active, and an expiry window — check all three on the promotions page before you deposit, because a headline in the thousands is only reachable by committing several thousand of your own. Limitation: the bigger the multiplier, the more the value depends on terms that can change without notice, and as with every brand here it operates outside UK Gambling Commission protection.
Kikibet — a spins-heavy offer with the usual free-spin caveats
Kikibet rates 9.9 with us for its slot range and the clarity of its cashier. The advertised welcome is 350% up to £5,555 and 300 free spins, with the spins normally dripped over several days and locked to named games. Free spins are where the small print bites hardest: spin value is usually fixed at the minimum, winnings arrive as bonus funds rather than cash, and there is often a cap on what can be withdrawn from them. Limitation: minimum qualifying deposits and game restrictions materially reduce what the 300-spin figure is worth in practice, and complaint escalation runs through an overseas licensing body rather than a UK route.
Betninja — a flatter, more readable offer
Betninja earns 9.9 for a different reason: its advertised £1,000 bonus and 100 free spins for all new players is a simpler proposition to evaluate than the four-figure multipliers elsewhere on the list, and a flat cash cap makes the wagering maths easier to do before you commit. That suits readers who want to understand the cost of clearing a bonus rather than chase the biggest number. Limitation: the ceiling is lower than most of the list, and the same overseas-licence caveats on dispute resolution and self-exclusion apply here as everywhere else on this page.

All offers are new-customer promotions subject to minimum deposit, wagering and expiry terms set by the operator. Where the advertised currency is euros or dollars, a British customer paying in pounds may face conversion at the casino's or the card issuer's rate — a real cost that rarely appears in the headline.
How money moves at casinos of this type
Taking part costs whatever you deposit, and nothing here is free: a percentage bonus only exists once your own money is at risk. Minimum deposits at sites in this category commonly start in the £10 to £20 region, though each cashier sets its own floor and we check it per brand rather than assuming.
- Debit cards — Visa and Mastercard are usually accepted; credit cards are banned for gambling in Great Britain and British issuers may decline or flag overseas gambling transactions regardless of the casino's stance.
- Bank transfer — slower in both directions, but often the route with the highest withdrawal ceiling.
- E-wallets — Skrill, Neteller and prepaid vouchers such as Paysafecard appear widely. PayPal is uncommon outside UK-licensed operators, so verify it at the cashier before relying on it.
- Cryptocurrency — accepted at several brands on this list and central to CoinPoker's model. Fast, but exchange-rate movement and network fees are yours to absorb, and a crypto deposit is not reversible.
On the way out, expect identity verification before a first withdrawal — photo ID, proof of address, and sometimes proof of payment method — plus source-of-funds checks on larger sums. Overseas casinos apply weekly and monthly withdrawal caps more often than UK sites do, so a five-figure win may be paid in instalments. If a payout stalls, your escalation route is the operator's complaints procedure and then its licensing authority; the UK Gambling Commission has no jurisdiction here, and neither does the Independent Betting Adjudication Service.
What is actually on offer at these sites
The game mix is broadly consistent across the category: slots make up the bulk of it, spanning low-volatility titles with frequent small returns and high-volatility games with long dry runs, plus progressive jackpots pooled across operators. Published RTP figures tell you the long-run theoretical return and say nothing about a single session. Live dealer rooms carry blackjack, roulette and baccarat streamed with human croupiers, alongside RNG versions of the same games at lower stakes. Almost everything runs in a mobile browser without a download.
Several of these operators also run a sportsbook beside the casino, usually on a shared wallet, with pre-match and in-play markets, accumulators, bet builders, cash-out and esports. Sports free bets work differently from casino bonuses — they hinge on minimum qualifying odds, often around 1.80 in decimal terms, and the stake is typically not returned with winnings. CoinPoker's emphasis is poker rather than slots, which is a different product again: you are playing other customers, with the house taking rake.
Eligibility, legality and what you are giving up
You must be 18 or over. Gambling at an overseas-licensed casino is not a criminal offence for a customer in Great Britain, but the operator is outside the Gambling Commission's remit, which means no GamStop integration, no UK complaints escalation, no British advertising standards on promotions, and no guarantee of the deposit-limit and reality-check tools that GB licences require. Some brands offer their own self-exclusion and limit tools voluntarily; that is a policy, not a legal protection. Winnings are not taxed for players in the UK, but currency conversion and payment fees can still erode them.
Nothing on this site is advice to gamble, and no casino can be described as completely safe. Gambling is entertainment paid for with money you can afford to lose — never a source of income or a way out of debt.
Corrections, questions and how to reach us
Terms change, brands disappear and licences lapse. If a figure here no longer matches what the operator publishes, tell us and we will recheck it and update the date. Our contact page is the fastest route, and the terms and conditions set out how the site itself operates. If you are weighing up whether to play at all, read the responsible gambling material first — that is the more useful page of the two.
