About Us

Non Gamstop Casinos is an independent research and comparison site covering offshore online casinos that accept British customers without connecting to the GAMSTOP self-exclusion scheme. Most operators we write about hold a licence from Curaçao, which is why our top lists lean heavily on Curaçao casinos not on GamStop. This page explains who we are, how we reach our conclusions, how we are paid, and what we cannot tell you.

We are not a casino, a bookmaker or a payment provider. We do not take deposits, hold player funds or settle bets. We publish research, and we say plainly when something is unverified.

What this site is for

British readers searching for casinos outside GAMSTOP usually want one of two things: they have registered with GAMSTOP and want to understand what sits beyond it, or they are comparing offshore sites on bonus size, payment options and game range. Both groups deserve accurate information about the trade-offs rather than a sales pitch.

So our writing concentrates on the parts of an offer that decide whether it is any good: wagering requirements rather than headline percentages, withdrawal limits rather than advertised speeds, and which licence actually sits behind the site. Our full comparison lives on the non GamStop casinos top list; this page is about the method behind it.

Our commercial relationships, stated plainly

We earn commission when a reader opens an account with some of the operators listed here. That funds the site. It does not buy a position, a rating or a favourable paragraph. Every write-up below carries at least one limitation, including the highest-ranked one, and we keep operators in our tables where the terms are demanding, because readers are better served seeing that than not seeing the site at all.

How we assess a Curaçao casino

Curaçao has restructured its gambling regulation under the Curaçao Gaming Authority, replacing the older master-licence and sub-licence arrangement. A Curaçao permit is a real licence, but it is not equivalent to a UK Gambling Commission licence. That distinction drives most of our scoring.

1. Licence check. We look for a named licence holder and a verifiable registration reference in the footer or terms, and we treat "accepts UK customers" as a separate matter from "authorised to serve Great Britain". Only UKGC-licensed operators are authorised for the British market, and only they must be in GAMSTOP.
2. Bonus terms, not bonus size. Wagering multiple, whether it applies to bonus or deposit plus bonus, game contribution rates, maximum bonus bet, expiry window and any cap on cashing out bonus winnings.
3. Payments for British customers. Whether GBP accounts are offered, whether debit cards, bank transfer, e-wallets, prepaid vouchers or cryptocurrency are genuinely available at UK sign-up, and what conversion or processing fees apply.
4. Withdrawals. Stated processing times, daily, weekly and monthly caps, and how KYC and source-of-funds checks are described.
5. Games and providers. Breadth of slots, live dealer tables and jackpots, and whether recognisable studios are present.
6. Support and complaints. Contact channels, published hours, and whether any independent dispute route is named.
7. Player tools. Deposit limits, loss limits, session reminders and account self-exclusion, which offshore sites offer inconsistently.

All of that is desk research: reading terms and conditions, licence pages, cashier pages and published policies, then re-checking them periodically. We have not deposited, played or withdrawn at these sites, and we never present advertised timings as tested results. Ratings here are editorial opinions, not customer-review averages. This page was last reviewed on 23 September 2026 by Jane Wetherall.

The operators we rank highest, and why

Betmica — rated 10.0

Betmica leads our list because it pairs a sterling-friendly sign-up with the broadest slot and live-dealer spread among the Curaçao-licensed sites we have catalogued, and because its terms are comparatively easy to find rather than buried three clicks deep.

Headline offer: a welcome package of 570% up to £5,700 plus 270 free spins. New accounts only, subject to a minimum qualifying deposit, wagering requirements on bonus and spin winnings, a maximum stake while a bonus is active, and an expiry window. Check the current figures in the cashier first, because tiered packages of this size usually split across several deposits rather than landing in one.

Limitation: a percentage that large is arithmetic, not generosity. The bigger the multiple attached, the more turnover it takes to clear and the more likely you are to run into the maximum-bet rule or a cashout cap. There is also no UK regulator to escalate a dispute to.

Kikibet — rated 9.9

Kikibet earns its place on payment flexibility and on the sportsbook sharing the same wallet, which suits readers who want casino and betting in one account rather than two.

Headline offer: 350% up to £5,555 and 300 free spins for new players, with a minimum deposit, wagering requirements and time limits attached; free spins are normally restricted to named slots.

Limitation: withdrawal caps are the pinch point rather than the deposit process. A large win can take several payout cycles to clear, and verification is generally requested before the first withdrawal rather than at registration.

Betninja — rated 9.9

Betninja is here for the opposite reason to the big-percentage sites. Its welcome offer is modest in headline terms, which usually means a shorter route to clearing it, so it works well as a reference point for what a realistic bonus looks like.

Headline offer: a £1,000 bonus and 100 free spins for all new players, subject to a qualifying deposit, wagering on bonus funds, game contribution rules and an expiry period.

Limitation: the catalogue and promotional calendar are narrower than at the largest operators, live-dealer choice is more limited, and as with every site on this page there is no UK consumer protection behind the account.

WinnerIsland — rated 9.9

Worth flagging for a different reason: its advertised welcome bonus of up to €1,000 plus 100 free spins is denominated in euros. If the account is not held in sterling, deposits and withdrawals may attract conversion costs from the casino, your card issuer or both, and the bonus ceiling moves with the exchange rate. Standard conditions apply — new players only, minimum deposit, wagering, expiry.

All of these are new-customer promotions governed by the operator's own terms: minimum deposit, wagering requirements, maximum bonus bet, game contribution rates, expiry dates and in some cases a limit on what bonus winnings can be withdrawn. Terms change without notice, so the operator's page is always the authority.

How the money works at offshore casinos

Reading this site costs nothing. Taking part costs whatever you deposit, and a deposit is at risk the moment it is staked — so nothing described here is free money.

• Minimum deposits commonly sit in the £10 to £20 range, and a welcome offer may require more than the site's floor to qualify.
• Debit cards are the most familiar route, though some UK issuers decline transactions to offshore gambling merchants. Credit cards are banned for gambling in Great Britain, and sensible offshore sites follow the same line.
• E-wallets are widespread; PayPal is rarely available outside the UKGC-licensed market, so verify it in the cashier rather than assuming.
• Prepaid vouchers such as Paysafecard appear at some sites for deposits but usually cannot receive a payout, meaning you need a second method to be paid.
• Bank transfer tends to allow the highest limits and the slowest timings.
• Cryptocurrency is common offshore and adds network fees and price movement on top of the casino's own terms.
• Fees and conversion matter more than they look. A euro or dollar balance means conversion on the way in and again on the way out.
• Being paid normally requires identity verification first, and often a source-of-funds check on larger sums. Expect caps stated per day, week or month, and expect a first withdrawal to be slower than later ones.

What you actually get to play

• Slots — the bulk of every library. We note return to player where it is published, and volatility, because a high-variance game clears wagering very differently from a low-variance one.
• Progressive jackpots — pooled prizes that grow until won, usually with a lower base RTP and often excluded from bonus play.
• Table games — blackjack, roulette and baccarat in software form, typically contributing 10% or less towards wagering, sometimes nothing at all.
• Live dealer rooms — real croupiers streamed in real time, plus game-show formats. Rarely eligible for clearing a bonus.
• Mobile play — most offshore sites run in a browser rather than an app, so we check whether the cashier and document upload work properly on a phone.

The sportsbook beside the casino

Several operators in our lists, Kikibet among them, run a betting product alongside the casino, often on a shared wallet. It is a different product with different rules: pre-match and in-play markets, accumulators, bet builders, cash-out and esports, with free bets rather than free spins as the usual promotion. Sports free bets normally carry minimum qualifying odds — 1.80 or higher is typical — and the stake is not returned on a winning free bet. Casino wagering and sportsbook turnover requirements remain separate obligations even when the balance is shared.

Eligibility, regulation and the protection you keep

You must be 18 or over. Sites outside GAMSTOP are licensed abroad, most commonly in Curaçao, and are not authorised by the UK Gambling Commission to serve customers in Great Britain. The practical consequences:

• GAMSTOP registration does not block these sites, because only GB-licensed operators must integrate with it. If you chose a six-month, one-year or five-year exclusion, device-level blocking software and a bank gambling block are the tools that still work offshore.
• UKGC rules on advertising, affordability and credit cards do not bind an offshore licensee, and the Gambling Commission cannot investigate a complaint about one.
• Complaints run through the operator's own procedure first. Where a licensee names an independent dispute service, use it; where none is named, escalation options are thin.
• Regulatory scope differs within the UK: the Gambling Commission covers Great Britain, while Northern Ireland operates under separate legislation.
• Free, confidential support is available from GamCare on 0808 8020 133, 24 hours a day.

Our responsible gambling guidance covers deposit limits, self-exclusion and blocking tools in more depth, and the terms and conditions set out how this site operates.

Where we draw the line

• We never describe a casino as completely safe, and we never guarantee a withdrawal or a win.
• We do not present gambling as income or as a fix for money trouble.
• We separate confirmed facts from operator advertising, and we say when a question is unresolved.
• We correct errors openly rather than quietly deleting them.

If something here is out of date, or an operator has changed its terms since we last checked, tell us. The contact page reaches the editorial team, and reader corrections are the fastest way we find problems.
