About Us

Non Gamstop Casinos is an independent research and comparison site covering non GamStop casinos for readers in the UK. This page explains who produces the content on guerillapolicy.org, how the rankings are put together, how the site earns money, and — just as importantly — what our reviews cannot tell you. If you are weighing up an offshore casino that accepts British customers, you should know how the information in front of you was produced before you act on it.

We are not a casino and we are not a betting operator. We do not take deposits, hold player funds or settle bets. We publish research, and we earn commission when readers open accounts through some of our links.

Where we stand on GamStop and UK licensing

GamStop is the free self-exclusion scheme that every operator licensed by the UK Gambling Commission must integrate with. Registering blocks your access to all GB-licensed gambling sites for the period you choose — six months, one year or five years — and the block cannot be lifted early.

The casinos covered on this site are licensed overseas rather than by the Gambling Commission, which is why GamStop registration does not reach them. That distinction matters in both directions. Accepting British customers is not the same thing as being authorised to serve them, and an overseas licence does not give you the protections attached to a Great Britain licence: no GamStop integration, no UK deposit limits regime, no access to the GB complaints routes, and no route to the Gambling Commission if a dispute goes badly. Note also that Gambling Commission regulation applies to Great Britain — England, Scotland and Wales — while Northern Ireland operates under separate gambling legislation.

If you registered with GamStop because gambling had become a problem, the honest advice is to stay excluded and to use the tools on our responsible gambling page, including GamCare's National Gambling Helpline on 0808 8020 133, blocking software and bank-level gambling blocks. Nothing on this site should be read as encouragement to work around a self-exclusion you put in place for your own protection. Gambling is entertainment that costs money; it is not income and it will not fix a financial problem.

Who writes the reviews

Editorial content here is produced and maintained by Janet Worsley, working to a fixed review framework rather than to operator briefs. Factual claims on the site carry a verification date — this page was last fact-checked on 23 September 2026 — because bonus terms, payment options and withdrawal limits change frequently and a review that is accurate in spring can be out of date by autumn.

We separate three kinds of statement, and we try to signal which is which:

• Confirmed information — details we have read directly in an operator's published terms, banking pages or licence records.
• Casino advertising — headline bonus figures and marketing claims, reported as claims with their conditions attached, never as findings.
• Unresolved questions — things we could not verify, such as ownership structures behind some white-label brands, or withdrawal speeds that vary too widely to state as fact.

How we assess a casino

There is no live testing behind these reviews. We do not claim to have deposited, played or withdrawn at the sites we cover, and you should be sceptical of any comparison site that claims otherwise at scale. What we do is read the documents and compare them consistently.

1. Licence and ownership — which regulator issued the licence, which company is named on it, and whether the same group runs other brands you may already have an account with.
2. Bonus terms in full — not the headline percentage, but the wagering multiple, whether it applies to bonus or deposit plus bonus, game contribution rates, maximum bet while a bonus is active, expiry windows and any cap on what can be cashed out from bonus winnings.
3. Payments for British customers — whether GBP accounts are offered, which of debit cards, bank transfer, e-wallets, prepaid vouchers and cryptocurrency are actually available to a UK registrant, and what fees or currency conversion apply.
4. Withdrawals — stated processing times, daily, weekly and monthly limits, and how KYC identity checks and source-of-funds requests are handled.
5. Games and providers — the breadth of slots, live dealer tables and jackpot titles, and which studios supply them, since recognised providers publish RTP figures.
6. Support and complaints — contact channels, stated hours and whether an independent dispute service is named in the terms.

Ratings are editorial scores from our own framework. They are not customer review averages, and advertised payout speeds are reported as advertised, never as measured.

How the site makes money

Non Gamstop Casinos earns affiliate commission when a reader signs up with certain operators through our links. Commercial relationships do not buy ranking positions, and no operator sees or approves a review before publication. Where a brand pays nothing, it can still appear; where a brand pays, it can still be criticised. The trade-off is real, though, and worth stating plainly: we make money when people open casino accounts, so read our ratings as one input alongside the operator's own terms, not as a substitute for them.

What our rankings look like in practice

Our ranked list leads with Betmica, and the entries below show the kind of reasoning that sits behind a placement. Full breakdowns live on the non GamStop casino rankings page.

Betmica — top of our list, and the largest headline offer

Betmica ranks first because it scores consistently across our framework rather than on one standout feature, and because its documentation is clear enough to compare. Its advertised welcome offer is 570% up to £5,700 plus 270 free spins, quoted in pounds, which matters for UK readers who would otherwise carry conversion costs on every deposit and withdrawal.

The limitation is the offer itself. A 570% match is only worth what its wagering requirement allows you to keep — check the multiple, the maximum stake permitted while the bonus is live, the expiry window and any cap on bonus winnings before you deposit. A five-figure headline attached to a tight cashout limit is a smaller offer than a modest match with clean terms.

Kikibet — a sizeable match with a straightforward structure

Kikibet earns its position on breadth and on an advertised 350% up to £5,555 with 300 free spins. The GBP framing again works in a British reader's favour, and the free spin allocation is large enough to be meaningful rather than token.

Against that: spin packages are commonly released in daily tranches on named slots, and winnings from them are often capped separately from the cash bonus. Read the spins terms as a distinct set of rules, not as an extension of the deposit match.

Betninja — a flat cash figure instead of a percentage

Betninja is included because its advertised £1,000 bonus and 100 free spins for new players is easier to reason about than a percentage match. You can see what the ceiling is without calculating it, which suits readers who find multi-tier packages opaque.

The drawback is that a flat ceiling usually means you need to deposit a substantial amount to reach it, and the qualifying minimum deposit and any per-tier conditions decide whether the advertised figure is realistically available to you at all.

Comparing the headline offers

Casino	Advertised welcome offer	Currency as advertised	Editorial rating
Betmica	570% up to £5,700 + 270 free spins	GBP	10.0
Kikibet	350% up to £5,555 + 300 free spins	GBP	9.8
Betninja	£1,000 bonus + 100 free spins	GBP	9.8
WinnerIsland	Up to €1,000 + 100 free spins	EUR	9.8
Zombillion	250% up to £4,000 + 200 free spins	GBP	9.8
Smash Casino	600% up to €10,000 slots package	EUR	9.8
Nightluck	805% up to €6,400 + 280 free spins	EUR	9.8
CoinPoker	150% up to $2,000	USD	9.8
Rivo	1000% up to €10,000 + 25% cashback	EUR	9.8
Daytonaspin	255% up to £4,500 + 255 free spins	GBP	9.8

All figures are as advertised by the operators and are subject to their own terms. Offers in euros or dollars — WinnerIsland, Smash Casino, Nightluck, CoinPoker and Rivo among them — mean a UK reader should check whether a GBP account is available, and if not, what conversion spread applies on both deposits and withdrawals.

Money: what it costs and how you get paid

Reading our site costs nothing. Taking part at any casino costs whatever you deposit, and that money is at risk. Minimum deposits at offshore sites commonly start in the £10 to £20 range, and bonus offers often set their own, higher qualifying minimum — a £10 deposit may not activate a package advertised from £20.

• Debit cards — widely accepted, usually instant on deposit. Credit cards are banned for gambling for GB-licensed operators; some UK card issuers decline offshore gambling transactions regardless of the site.
• Bank transfer — higher limits, slower, typically one to several working days once approved.
• E-wallets — generally the quickest withdrawal route where offered. PayPal availability at non GamStop casinos is limited and should never be assumed; verify it on the cashier page before depositing.
• Prepaid vouchers — useful for deposits, but rarely usable for withdrawals, so you will need a second method for payouts.
• Cryptocurrency — common offshore and often fast, but the value of your balance can move between deposit and withdrawal, and conversion charges apply at both ends.

Withdrawals are where the practical differences show. Expect an internal review period before funds are sent, plus the payment provider's own clearing time. Daily, weekly and monthly caps are normal, and a large win may be paid in instalments over weeks. Before your first withdrawal you will be asked to complete KYC identity verification — photo ID, proof of address, and proof of the payment method. Larger balances can trigger source-of-funds checks requiring payslips or bank statements. Submitting documents early avoids delay; refusing them stops a payout. If a withdrawal is disputed, your only route is the operator's complaints procedure and any independent adjudicator named in its terms, since the Gambling Commission has no jurisdiction over an overseas licensee.

What these casinos actually offer

The catalogues we review break down into recognisable categories:

• Slots — the bulk of every library. The two numbers worth checking are RTP, the long-run theoretical return, and volatility, which describes how streaky the outcomes are. High volatility means longer dry spells and larger occasional wins.
• Progressive jackpots — pooled prizes that grow until won. Some require a maximum-stake bet to qualify, which conflicts with the bet caps imposed while a bonus is active.
• Live dealer rooms — streamed blackjack, roulette and baccarat with real dealers. These usually contribute little or nothing towards wagering requirements.
• Table games — software blackjack, roulette and baccarat, typically contributing at a reduced rate to bonus wagering.
• Mobile play — most of these sites run in a mobile browser rather than through an app, so check how the cashier and verification upload behave on a phone.

The sportsbook running alongside

Several of the operators we cover run a sportsbook beside the casino, and it works to different rules. Sports markets cover pre-match and in-play betting, accumulators, bet builders, esports and cash-out. Sports free bets usually carry minimum qualifying odds — commonly around 1.50 in decimal terms — and the stake is not returned with winnings. Where a casino and sportsbook share a single wallet, a casino bonus may lock funds you intended to bet with, so read which side of the account a promotion applies to. Some brands, such as CoinPoker, are built around poker rather than a conventional sportsbook, and their bonus structures release against rake or play rather than a straightforward wagering multiple.

Who can use these sites, and what that means for you

You must be 18 or over. Operators verify age as part of KYC, and accounts that fail verification are closed with winnings typically forfeited. Beyond age, eligibility is set by each casino's terms — some restrict certain countries, some restrict bonus access by payment method, and terms of use may exclude readers who have self-excluded elsewhere. Your own obligations include giving accurate registration details, completing verification honestly and keeping one account per person.

We do not describe any casino as completely safe, and we cannot guarantee that a withdrawal will be paid. What we can do is set out the terms clearly and tell you which checks to make yourself. Our full terms of use explain the basis on which this information is published.

Getting in touch

If a bonus term on this site no longer matches what an operator publishes, or you think a ranking is wrong, tell us — corrections from readers are one of the more reliable ways we catch changes. The contact page is the fastest route. And if what you actually need is help rather than a comparison, GamCare's helpline on 0808 8020 133 is free, confidential and open to anyone in the UK.
