About Us
Non Gamstop Casinos is an independent research and comparison site for UK adults who are looking into new casinos not on GamStop. This page explains who the site is for, how the rankings on thesustainableedit.com 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 a payment provider. We do not take deposits, hold funds or settle bets. We publish written research about offshore-licensed operators that accept British customers, so that readers can see the terms attached to a bonus before signing up rather than after.
Why this site focuses on newer offshore casinos
GamStop is the free self-exclusion scheme that every operator licensed by the Great Britain 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. Casinos "not on GamStop" are those outside that system: they hold licences from other jurisdictions, commonly Curaçao, and are therefore not connected to the scheme and not covered by Gambling Commission consumer protections.
That distinction matters more for new sites than for established ones. A casino that launched recently has little public track record: no long history of complaint outcomes, no settled reputation for how it handles a large withdrawal or a source-of-funds request. Our job is to set out what can actually be verified about these operators, and to be plain where the answer is "not yet known".
If you are currently registered with GamStop, the honest advice is not to seek a way around it. Self-exclusion works best when it is not tested. Support is available free from GamCare on 0808 8020 133 or through the National Gambling Helpline, and blocking software such as Gamban or BetBlocker can reinforce a break. Our responsible gambling guidance covers deposit limits, loss limits, exclusion periods and where to get help.
How we earn money, and what that does not buy
Non Gamstop Casinos earns commission when a reader follows a link to an operator and opens an account. That is the whole of our revenue model, and you should factor it in when you read any comparison page, including ours.
What commission does not do: it does not set the order of our lists, it does not add a casino to them, and it does not stop us writing down a drawback. Operators have no sight of drafts and no approval over ratings. Where a site has a weakness that is relevant to a UK reader — a currency that is not sterling, a restrictive withdrawal cap, a bonus with terms that are hard to clear — we say so beside the offer, not in a footnote.
How we research and rate a casino
There is no testing team here. We do not deposit, play or withdraw. Every rating on this site is an editorial score derived from documented research, not from customer reviews and not from a lab. Here is what goes into it.
- Licence and ownership — which regulator is named, which company operates the site, and whether that information is published and consistent. We check the stated licence rather than assuming one exists.
- Bonus terms in full — the wagering multiple, whether it applies to bonus or deposit plus bonus, game contribution rates, maximum bet while a bonus is active, expiry dates and any cap on what can be cashed out from bonus play.
- Payments for British customers — whether GBP accounts exist, which debit card, bank transfer, e-wallet, prepaid and cryptocurrency options are listed, and whether conversion costs apply. PayPal is rarely available outside the GB-licensed market; we verify rather than assume.
- Withdrawals — stated processing times, daily, weekly and monthly limits, and how KYC and source-of-funds checks are described.
- Games and providers — the mix of slots, jackpots, table games and live dealer rooms, and which studios supply them.
- Support and complaints — contact channels, stated hours, and whether an external dispute route is named.
Advertised withdrawal speeds are exactly that — advertised. We report them as operator claims, and they are not a promise. Findings are dated, and the research behind this page was last reviewed on 23 September 2026.
Three of the operators we rank, and what we flag on each
Our full reviews of non GamStop casinos go further, but the three highest-rated sites give a fair sense of how we weigh a headline figure against its conditions.
Betmica — the largest headline package we list
Betmica sits at the top of our table with an editorial rating of 10.0, largely because it combines a sterling-denominated offer with the broadest promotional structure of the new arrivals we reviewed. The advertised welcome offer is 570% up to £5,700 plus 270 free spins, typically spread across several qualifying deposits rather than paid on the first alone. Treat the £5,700 as a ceiling that requires very large total deposits; the realistic figure for a modest first deposit is a small fraction of it. Limitation: a percentage that size usually arrives with a substantial wagering multiple and a maximum bet cap while the bonus is live, and Betmica's short operating history means there is no settled public record of how it handles disputed or high-value withdrawals.
Kikibet — sterling accounts with a simpler structure
Kikibet is rated 9.9 and earns its place for a welcome offer that is easier to read than most: 350% up to £5,555 and 300 free spins. Fewer moving parts generally means fewer ways to void a bonus by accident. Free spins are commonly restricted to named slots and may carry their own wagering on winnings, so check which titles qualify before you claim. Limitation: a narrower promotional range after the welcome period than some rivals, and as with every site here, no Gambling Commission oversight and no GamStop link.
Betninja — a flat cash figure rather than a percentage
Betninja, also rated 9.9, is listed because its £1,000 bonus and 100 free spins for all new players is quoted as a fixed amount in pounds. That makes the maximum easier to judge against a deposit you would actually make, and it removes the currency conversion question that arises on euro-denominated offers. Limitation: a £1,000 ceiling is modest next to the packages above it, and "all new players" still means the usual eligibility rules — one account per person and household, minimum deposit, and completed identity verification before any withdrawal.
How the headline offers compare

|---|---|---|---|
| Betmica | 10.0 | 570% up to £5,700 + 270 free spins | GBP |
| Kikibet | 9.9 | 350% up to £5,555 + 300 free spins | GBP |
| Betninja | 9.9 | £1,000 bonus + 100 free spins | GBP |

| Nightluck | 9.7 | 805%, €6,400 + 280 free spins | EUR |
| CoinPoker | 9.7 | 150% up to $2,000 | USD |

| Daytonaspin | 9.6 | 255% up to £4,500 + 255 free spins | GBP |
All offers are as advertised by the operator and subject to that operator's terms. Euro and dollar figures indicate the account currency the offer is quoted in; if your funding account is in sterling, expect a conversion cost on both deposits and withdrawals.
Money in, money out — what we always check
Deposit methods vary by operator and we only report what a site actually lists. Across this category the common options are debit cards, bank transfer, e-wallets, prepaid vouchers including Paysafecard, and cryptocurrency. Card deposits are usually instant; bank transfers take longer both ways. Crypto tends to be the fastest route out but exposes you to price movement between request and receipt.
- Minimum deposit — often £10 to £20, and frequently higher than that to qualify for a welcome bonus. The qualifying figure is the one that matters.
- Fees and conversion — an operator may charge nothing while your bank or card issuer applies a conversion or cash-advance charge on a euro or dollar account.
- Withdrawal limits — daily, weekly and monthly caps are normal offshore. A large win can be paid in instalments over weeks.
- Verification — expect KYC before a first payout: photo ID, proof of address, proof of payment method. Larger or unusual amounts can trigger source-of-funds checks requiring payslips or bank statements.
- Bonus cashout caps — winnings from bonus funds are often capped at a multiple of the bonus, regardless of what the spins produced.
What these sites offer beyond the welcome package
The casinos we cover typically run several product lines from one account. Slots dominate — low, medium and high volatility titles, with RTP normally published in the game information panel and progressive jackpots pooled across operators. Table games cover blackjack, roulette and baccarat in both RNG and live dealer form, with live rooms streamed from studios and open at fixed or continuous hours. Most sites are built mobile-first, played in the browser rather than through an app.
Alongside the casino, many of these brands run a sportsbook on a shared wallet: pre-match and in-play markets, accumulators, bet builders, cash-out and esports. Sports promotions work differently from casino ones — free bets usually carry minimum qualifying odds, often around 1.50 to 2.00 in decimal terms, and the stake is not returned with winnings. A few operators, CoinPoker among them, centre on poker rather than slots, which changes both the bonus mechanics and how wagering is cleared. Read the sportsbook and poker terms separately; casino bonus rules rarely transfer.
Eligibility, legal standing and what it means for you
You must be 18 or over. The operators listed here are licensed outside Great Britain and are not authorised by the UK Gambling Commission, so the protections that come with a GB licence — GamStop integration, the Commission's complaints framework, UK deposit-limit and advertising rules — do not apply. Accepting British customers is not the same as being authorised to serve them, and we are careful not to blur the two.
In practice that means your recourse in a dispute is the operator's own complaints procedure first, then whatever alternative dispute resolution its licensing jurisdiction provides, which is usually less accessible than the GB route. No site can be described as completely safe, no withdrawal can be guaranteed, and gambling is never a way to make money or solve a financial problem. Our terms and conditions set out the limits of the information published here.
Getting in touch
If an offer on this site no longer matches what the operator advertises, or you think a rating is wrong, tell us — corrections from readers are one of the more reliable ways we catch changes. The contact page is the fastest route. We cannot intervene in a dispute between you and a casino, and we do not hold accounts on your behalf, but we will update what we publish when the facts change.
