About Us
Non Gamstop Casinos is an independent research and comparison site covering casinos not on GamStop for readers in Great Britain. This page explains who produces the content, how the rankings on our main list of non GamStop casinos are put together, where our money comes from, and — just as importantly — what our research cannot tell you.
We are not a casino, a bookmaker or an operator. We do not take deposits, hold player funds or settle bets. We publish written research about sites that accept British customers without being connected to the GamStop self-exclusion scheme, most of them licensed overseas rather than by the UK Gambling Commission.
Why this site focuses on new casinos not on GamStop
GamStop is the free, national self-exclusion scheme for online gambling operators licensed by the UK Gambling Commission to serve Great Britain. Once you register with GamStop, every UKGC-licensed site must block your account for the exclusion period you chose — six months, one year or five years — and it cannot be lifted early.
Casinos not on GamStop sit outside that system because they hold licences from other jurisdictions, such as Curaçao, rather than from the UK Gambling Commission. Accepting British customers is not the same thing as being authorised to serve them, and that distinction runs through everything we publish. An overseas licence means a different complaints route, a different set of consumer protections, and no recourse to the UK regulator if something goes wrong.
Our readers arrive with a range of reasons for searching. Some are comparing bonus terms. Some want payment methods their existing account does not offer. Some are registered with GamStop and are looking for a way around it. If you are in that last group, please read our responsible gambling page before anything else on this site. Working around a self-exclusion you set for yourself is a warning sign, and GamCare's National Gambling Helpline (0808 8020 133, free, 24 hours) exists for exactly that conversation.
How we make money, stated plainly
Some links on this site are commercial. If you open an account with a casino after following one of them, Non Gamstop Casinos may receive a commission from that operator. You pay nothing extra, and the terms you see are the terms the operator advertises publicly.
Commission does not buy a position in our rankings, a rating, or a favourable sentence. Operators cannot review their write-ups before publication. Where a site has a weakness we consider material — an unclear licence, punishing wagering terms, slow or capped withdrawals — we say so, including for the sites at the top of the list. We also cover casinos we would not personally recommend, because readers searching for them deserve accurate information rather than silence.
How we research and rank a casino
Our work is desk research and verification, not play-testing. We have not deposited, wagered or withdrawn at the casinos we cover, and we never present advertised speeds or headline bonus figures as results we have confirmed in practice. Here is the sequence we follow:
- Licence check. We look for a named licensing authority and licence number on the operator's own pages, and check whether the site claims or implies UK Gambling Commission authorisation it does not hold.
- Ownership and operating entity. We record the company named in the terms and conditions, and note where several brands share one operator — which matters, because a dispute with one can affect the others.
- Full bonus terms, not the banner. We read wagering requirements, game contribution rates, maximum bonus bets, expiry dates and cashout caps, then judge the offer on those, not on the percentage.
- Payments and currency. We check whether GBP accounts are available, which deposit and withdrawal methods are listed for British customers, and whether conversion or processing fees apply.
- Withdrawal rules. Stated processing times, daily, weekly and monthly withdrawal limits, and the KYC and source-of-funds checks the operator says it will run.
- Games and providers. The mix of slots, live dealer tables and jackpots, and whether recognisable software studios are named.
- Support and complaints. Contact channels, stated hours, and whether there is any named external dispute route.
- Player safety tools. Deposit limits, loss limits, time-outs and account closure — and how easy they are to find.
Ratings on this site are editorial scores produced by us from the factors above. They are not customer-review averages and should not be read as one. Findings are dated, and terms change without notice — always confirm the current offer on the operator's own site before depositing.
Examples of how the top-ranked sites are assessed
The three write-ups below show the method applied, working from the top of our list. Full reviews sit on the ranked comparison page.
Betmica
Betmica holds our highest editorial score, 10.0, largely because its offering is broad across slots, live dealer tables and sports markets, and its bonus structure is documented in reasonable detail. Its advertised welcome offer is 570% up to £5,700 plus 270 free spins, which is spread across the first deposits rather than paid on one — check the minimum deposit, the per-deposit match rate, the wagering multiple, the maximum bet allowed while a bonus is active and the expiry window before you opt in. The limitation: a headline of this size is arithmetic, not generosity. The larger the match, the larger the amount you must turn over to clear it, and the more likely a winnings cap applies. Betmica also operates under an overseas licence, so UK Gambling Commission protections do not apply to your account.
Kikibet
Kikibet scores 9.8 and is on this page because its welcome package — 350% up to £5,555 and 300 free spins — is quoted in pounds, which is a practical signal for British readers hoping to avoid currency conversion on every deposit and withdrawal. A GBP-denominated offer does not guarantee a GBP account, so verify the currency at registration; it usually cannot be changed afterwards. The limitation: free spins packages are commonly drip-fed over several days, restricted to named slots and subject to their own wagering and win caps, which are easy to miss under a large headline number.
Betninja
Betninja also scores 9.8, and it is the most straightforward of the three: £1,000 bonus and 100 free spins for all new players, with no tiered percentage to unpick. A flat, clearly stated offer is easier to evaluate, and in our experience of reading terms, easier terms usually mean fewer surprises at withdrawal. The limitation: "all new players" still means the standard exclusions — minimum deposit, minimum qualifying deposit method, one bonus per household or IP address, and excluded payment methods on some sites. Confirm which deposit routes qualify before you fund the account.

All offers are as advertised by the operator and subject to their terms. Where an offer is quoted in euros or dollars, expect currency conversion on deposits and withdrawals from a UK bank card or account.
What we tell readers about costs and payments
There is no charge for reading this site. The cost of taking part sits entirely with the operator you choose, and our guides consistently press on four points.
- Minimum deposit. Often £10 or £20, but a bonus may carry a higher qualifying minimum than the site's general one.
- Payment methods. Debit cards, bank transfers, e-wallets, prepaid vouchers and cryptocurrency are the usual routes at offshore casinos. Availability for British customers varies by operator and changes often — PayPal in particular is rarely offered outside UKGC-licensed sites. Check the cashier page for your own country before you commit.
- Fees and conversion. Operators may not charge, but your bank or card issuer can, and a euro- or dollar-denominated account adds a conversion spread each way. Crypto adds network fees and price movement between deposit and withdrawal.
- Withdrawals. Advertised processing times are goals, not promises. Daily, weekly and monthly caps are common, bonus winnings may be capped separately, and payouts are normally released only after identity verification. Expect to supply photo ID, proof of address and, for larger sums, source-of-funds evidence. We never guarantee that a withdrawal will be paid.
The games and betting we cover
Our reviews describe what is actually in a lobby rather than counting titles. In practice that means slots — including progressive jackpots, and the RTP and volatility figures that explain how a game behaves; live dealer rooms with blackjack, roulette and baccarat streamed from studios; and traditional software table games. We name software providers only where the operator lists them, and we do not publish game counts we cannot verify.
Most of these brands run a sportsbook alongside the casino, and it usually shares one wallet with your casino balance — worth knowing, because bonus terms often differ between the two. Sports coverage typically spans pre-match and in-play betting, accumulators, bet builders, cash-out and esports, with free bets that carry minimum qualifying odds, commonly around 1.50 in decimal terms. A casino bonus rarely converts to sports betting, and sports free bets rarely count towards casino wagering.
Eligibility and the legal picture in Great Britain
You must be 18 or over to gamble. Operators licensed by the UK Gambling Commission must participate in GamStop and follow British rules on advertising, deposit limits, affordability and dispute resolution; sites outside that framework do not. If you have a complaint against an overseas casino, your route runs through the operator's own procedure and then whatever body its licensing jurisdiction provides — not the Commission, and not the UK courts in any practical sense.
Note also that gambling regulation applies to Great Britain — England, Scotland and Wales. Northern Ireland has separate legislation. We keep that distinction explicit because it affects which rules apply to you.
Nothing here is legal or financial advice, and nothing on this site should be read as a suggestion that gambling is a way to make money or fix a financial problem. Set deposit and loss limits, use time-outs, and if you need the tools: GamStop covers UKGC sites, blocking software such as Gamban or BetBlocker covers the ones it does not, and GamCare provides free confidential support.
Who writes this
Editorial work on Non Gamstop Casinos is led by Hannah Rockwell, writing as a consumer editor rather than an industry insider. Pages carry a last-updated date, and time-sensitive findings — bonus terms, payment availability, licensing details — are checked against operator sources when a page is revised. The research reflected in this page was last verified on 23 September 2026.
We correct things. If a bonus term has changed, a payment method has been withdrawn, or we have got something wrong, tell us through the contact page and we will check it and amend. Our terms and conditions set out how the site may be used.
If you are deciding where to start, the practical advice we would give is the same one we apply ourselves: ignore the largest headline number, open the bonus terms, find the wagering multiple and the withdrawal cap, and compare on those. The ranked list is a starting point for that comparison, not a recommendation to sign up today.
