About Us
Non Gamstop Casinos is an independent research desk covering offshore online casinos that accept British players but sit outside the GAMSTOP self-exclusion scheme. This page explains who writes the site, how we assess the casinos we list, where our money comes from, and what we deliberately do not claim. If you want the rankings themselves, they live on our main non GamStop casinos list; this page is about the method behind them.
Why this site exists
Search for a casino not on GamStop and you will find plenty of pages that list bonus headlines and stop there. The parts that decide whether an account is worth opening — wagering requirements, maximum bonus bets, cashout caps, withdrawal limits, whether the site even holds a GBP wallet — usually sit in terms pages nobody reads.
Our work is to read those terms, write them in plain English, and be straight about the trade-offs. Casinos licensed outside Great Britain are not covered by the UK Gambling Commission's rules, so the consumer protections British players may be used to do not automatically apply. We think readers should understand that before they deposit, not after a withdrawal is queried.
Who writes it
Editorial output is led by Oscar Lyndhurst, who writes and maintains the reviews, comparison tables and explainer guides. The site is written for adults aged 18 and over. We are a publisher and a research team, not a regulator, not a dispute service, and not an affiliate of any operator's compliance department.
Factual checks on this page were last completed on 23 September 2026. Bonus terms, payment options and processing times change often, so we date time-sensitive findings and re-check listed casinos on a rolling basis. Where something could not be confirmed from the operator's own published terms, we say so rather than filling the gap.
How we make money
Some links on this site are commercial. If you open an account through one, we may be paid a commission by the operator. That costs you nothing extra and it does not change the offer you receive.
What it also does not do is buy a position. Rankings, ratings and the criticism inside each review are set editorially. An operator cannot pay to be added, pay to move up, or pay to have a limitation removed from its write-up. Where a casino has a weakness that matters — a high wagering multiplier, a low monthly withdrawal ceiling, a currency that is not sterling — we print it, commercial relationship or not.
What we check before a casino is listed
- Licence and ownership. Which authority issued the licence, which company holds it, and whether that company publishes a real corporate address. Offshore licences — Curaçao is the most common — carry lighter obligations than a UK Gambling Commission licence, and we never describe an offshore permission as UK authorisation.
- Bonus terms in full. The advertised headline, then the wagering requirement, the game contribution percentages, maximum bet while a bonus is active, expiry window, and any cap on what can be withdrawn from bonus winnings.
- Money in and out. Minimum deposits, whether GBP accounts exist or balances convert, which debit card, bank transfer, e-wallet or crypto routes are supported, fees, and stated withdrawal processing times and limits.
- Verification demands. What KYC documents are requested, at what point, and whether source-of-funds checks are mentioned in the terms.
- Games and suppliers. The mix of slots, live dealer tables and jackpot titles, and which software providers supply them.
- Support and complaints. Contact channels, published languages, and what the terms say about escalating a dispute.
- Player safeguards. Whether the operator offers its own deposit limits, loss limits, time-outs or account closure — since GAMSTOP registration does not reach these sites.
We research and verify published information. We do not claim to have deposited, played or withdrawn at any casino, and we do not present editorial ratings as customer review scores or advertised payout speeds as measured results.
Examples of how our write-ups read
Three of the casinos on our list, with the reasoning we would apply to any entry. The offers below are the operators' own advertised headlines at the time of checking, and each carries terms you should read at source before claiming.
Betmica
Betmica sits at the top of our current list on an editorial rating of 10.0, largely because it combines a sterling-denominated headline offer with a broad slots and live dealer catalogue — a combination that is less common than the marketing suggests among sites that take British players. Its advertised welcome offer is 570% up to £5,700 plus 270 free spins, which is a staged package rather than a single match, and is subject to minimum deposit, wagering and maximum-bet rules set by the operator. The limitation: a percentage that large almost always arrives with a heavy playthrough and a cap on bonus-derived withdrawals, so the practical value is far below the headline number. Treat the £5,700 as a ceiling on a multi-deposit sequence, not a figure anyone should expect to clear.
Kikibet
Kikibet earns its 9.9 for breadth — a slots-led library with live tables alongside — and for pricing its welcome package in pounds, at 350% up to £5,555 with 300 free spins. Compared with Betmica the match percentage is lower, which in practice often means a slightly less punishing wagering condition, though you should confirm the multiplier and expiry on the operator's terms page rather than assuming. The drawback is that free spin allocations of this size are usually released in daily tranches on named titles, with their own separate wagering on winnings, so the 300 figure is not available on day one and is not interchangeable with cash.
Betninja
Betninja is here as the more restrained option, and that is the point of its inclusion: £1,000 bonus and 100 free spins for all new players is a smaller headline than others on the list, and smaller headlines are generally easier to clear. It also runs a sportsbook alongside the casino, which suits readers who want one wallet for both. Its rating of 9.9 reflects that balance. The limitation is that a modest package gives you less room if you intend to play high-volatility slots, and as with every entry here, "all new players" still means players who meet the operator's country, age and verification requirements.
How the listed offers compare at a glance
Headline terms only, as advertised. Currency matters: an offer quoted in euros or dollars will usually mean conversion on deposit and withdrawal for a UK player.

How we treat the money side
Opening an account is free; taking part is not. A welcome bonus requires a qualifying deposit, and minimums are typically set by the operator and stated in the bonus terms — we quote them where they are published rather than estimating. We never describe a bonus as free money when a deposit or a wagering commitment is attached, and free spins are only genuinely free where no deposit is required, which is rare among the packages above.
On payments, we check which of the following an operator actually supports for British customers rather than assuming from a logo row: debit cards, bank transfers, e-wallets including whether PayPal is genuinely available (it frequently is not at offshore sites), prepaid vouchers such as Paysafecard, and cryptocurrency. For each we look at minimum and maximum amounts, any deposit or withdrawal fee, and the operator's stated processing time.
Withdrawals get the closest reading. Offshore sites commonly apply daily, weekly or monthly payout ceilings, and large wins may be paid in instalments. Identity verification is usually required before the first withdrawal, and source-of-funds documentation can be requested for larger sums. If a balance is held in euros or dollars, a UK reader should expect a conversion spread at both ends on top of any bank charge.
What we cover beyond the casino floor
Our reviews break the offering into the categories that actually behave differently: slots, where we note volatility and published RTP where the provider discloses it; progressive jackpots, which pool across operators; live dealer rooms streaming blackjack, roulette and baccarat with real tables and staff; and mobile play, since most of these sites run in a browser rather than an app.
Most of the operators here also run a sportsbook beside the casino, and it works on different logic. That means pre-match and in-play markets, accumulators, bet builders, cash-out, esports, and free bets carrying minimum qualifying odds — a free bet at odds of 1.50 often will not qualify where the terms specify 1.80 or above. Where a shared wallet exists, casino wagering and sports wagering may count differently towards the same bonus, and we flag that. CoinPoker's poker-led model is a further variation: table games against other players rather than the house, with rake and tournament structures instead of house edge.
Legal standing, eligibility and what it means for you
Every casino covered here is licensed outside Great Britain — offshore jurisdictions such as Curaçao are typical — and none of them holds a UK Gambling Commission licence. Accepting British customers is not the same as being authorised to serve them, and we are careful never to blur the two.
The practical consequences for a UK reader are concrete. UKGC rules on advertising, affordability checks, deposit limit tools and dispute resolution do not apply. GAMSTOP registration, which blocks accounts across Great Britain-licensed operators, has no effect on a site outside that scheme — and GAMSTOP exclusions run for a minimum of six months, one year or five years, with no facility for early release. If you are currently excluded, the responsible route is to let the period run, and to consider blocking software such as Gamban or BetBlocker and bank-level gambling blocks as additional barriers.
If a dispute arises at an offshore casino, escalation goes to the operator's own complaints procedure first, then to whatever body its licence names — a process that is generally slower and less certain than the UK route. You must be at least 18, and operators may restrict or close accounts for reasons set out in their own terms. Nothing on this site is legal or financial advice, no casino is ever described here as completely safe, and no withdrawal or winning outcome is guaranteed. Gambling is entertainment with a cost, never a way to make money or fix a financial problem.
Free, confidential support in the UK is available from GamCare on 0808 8020 133, and our responsible gambling resources set out the tools worth having in place before you play.
Where to go next
If you came here to judge whether our rankings are worth trusting, the short version is: read the limitation paragraph in any review before the bonus figure, and check the operator's own terms before depositing. If something on the site looks out of date or wrong, tell us — reader corrections are one of the ways listings get fixed. You can reach the editorial team through our contact page, and the rules governing use of the site are set out in the terms and conditions.
