Contact Us
This page is for getting in touch with the editorial team behind Non Gamstop Casinos. We publish research-based reviews of Curaçao casinos not on GamStop for UK readers, and we would rather hear from you than leave an error on the page. Use the contact form on calcgenie.com and tell us which review, which operator and which claim you are asking about — the more precise the message, the faster the answer.
One thing to be clear about before you write: we are a comparison and review publisher, not a gambling operator. We cannot open, close, verify or fund a casino account, cannot release a withdrawal, cannot apply a bonus code and cannot remove you from GAMSTOP or add you to it. Anything involving your money or your account has to go to the casino itself, and then to its complaints route. What we can do is explain the terms, point you at the right escalation path, and correct our own coverage.
What to send us, and what to send elsewhere

How we earn, stated plainly
Some links to the casinos we cover are commercial. If you follow one and register, we may receive a commission from the operator. That payment does not buy a position, a rating or a kind sentence, and we name limitations for every site we list, including the top-ranked one. If you think a review reads like an advert, that is exactly the sort of message worth sending.
Questions about the sites we list
Most messages we get are about specific operators and their headline offers, so here is the context we usually end up repeating. All of these carry wagering requirements, game weightings, maximum bonus bet caps, expiry dates and cashout limits set by the operator, and those terms can change without notice. Read the promotion page before you deposit.
Betmica
Betmica sits at the top of our list because its advertised Welcome Offer of 570% up to £5,700 plus 270 free spins is one of the largest headline packages among the Curaçao-licensed casinos not on GamStop that accept British customers, and because it presents itself clearly to UK readers rather than burying the detail. Our editorial rating is 10.0, which reflects breadth of offer and clarity of presentation, not a customer-review score and not a test of payouts.
The limitation is the arithmetic behind the number. A 570% match is only reachable by depositing at the top of the band, and a large bonus balance attached to a standard wagering multiple and a per-spin bonus bet cap can take a very long time to clear. Check the maximum you can withdraw from bonus winnings before you judge the headline. Verify too whether your account is billed in pounds; if the casino settles in euros, your card issuer may add a conversion cost on every deposit and withdrawal.
Kikibet
Kikibet earns its place for a similar reason with a different shape: 350% up to £5,555 and 300 free spins, quoted in sterling, with the free spins element weighted heavily. Editorial rating 9.9. For readers who care more about spin volume than match percentage, it is a useful comparison point against Betmica.
The drawback is that free spins are the most condition-heavy part of any welcome package. They are usually locked to named slots, often released in daily tranches, and winnings from them frequently carry their own wagering requirement and a separate cap. Three hundred spins at a low fixed stake is a smaller sum than it sounds. Ask support, in writing, what the spin value and the cap are.
Betninja
Betninja is on the list as the more restrained option: £1,000 bonus and 100 free spins to all new players, also rated 9.9 editorially. A smaller match on a sterling figure is generally easier to clear than a four- or five-figure package, which matters if you intend to withdraw rather than chase a jackpot.
Its limitation is the flip side of that: readers who deposit larger amounts get proportionally less back than the aggressive packages above it, and "to all new players" still means the usual eligibility rules — one bonus per person, household and IP address, minimum deposit, and minimum qualifying odds if any part of the offer touches the sportsbook.
How the rest of the list compares

| Zombillion | 250% up to £4,000 + 200 free spins | GBP | 9.9 |
| Smash Casino | 600% up to €10,000 slots package | EUR | 9.6 |
| Nightluck | €6,400 + 280 free spins + 805% | EUR | 9.6 |

The currency column is the one UK readers most often overlook. Offers quoted in euros or dollars, as at WinnerIsland, Smash Casino, Nightluck, CoinPoker and Rivo, generally mean conversion on the way in and the way out. Full write-ups sit on our reviewed list of non GamStop casinos.
Money questions we can answer, and the ones only the casino can
We can explain how a cost usually works. We cannot tell you what a specific account will be charged today — that belongs in the cashier terms.
- Minimum deposits — typically set per method, and a bonus often has a higher qualifying minimum than the cashier does. Depositing under the qualifying amount is the most common reason a welcome offer never appears.
- Debit cards — Visa and Mastercard debit are the usual UK route. Credit cards are banned for gambling in Great Britain, and some issuers decline gambling transactions regardless of the merchant.
- Bank transfers — slow but high-limit, and generally the method used for larger payouts.
- E-wallets and PayPal — e-wallets are common at offshore sites; PayPal is not, since it works almost exclusively with operators licensed in the player's jurisdiction. Never assume PayPal is available, check the cashier.
- Cryptocurrency — widely accepted at Curaçao-licensed casinos and central at a poker-led site like CoinPoker. It removes card declines but adds network fees and price movement, and it is not a consumer-protected payment.
- Fees and conversion — the casino may charge nothing while your bank still applies a non-sterling transaction fee. Two costs, two sources.
- Withdrawal timing and limits — expect a pending or reversal window, then processing. Daily, weekly and monthly caps are normal, and a large win is often paid in instalments. Read the cap before you chase a progressive jackpot.
- KYC and source of funds — identity documents, proof of address and, for bigger sums, evidence of where the money came from. Uploading documents on day one rather than at first withdrawal prevents most delays.
If a payout has stalled, our practical advice is unglamorous: put the complaint in writing to the casino, keep timestamps, quote the specific term you believe has been breached, and escalate through the operator's published complaints procedure and any dispute body named in its terms. We cannot arbitrate, and nobody can guarantee a withdrawal.
Game and sportsbook queries
Readers often write to ask what these sites actually contain. The spread across the operators we list runs roughly as follows: slots, including progressive jackpot titles, from third-party software providers; table games such as blackjack, roulette and baccarat in RNG form; live dealer rooms streaming the same table games with human croupiers; and, at several sites, a sportsbook sharing one wallet with the casino. CoinPoker leads with poker rather than slots, which is why its offer structure differs from the rest.
Two mechanics are worth understanding before you email us about a losing session. Return to player (RTP) is a long-run average built into a game, not a promise about your afternoon. Volatility describes how that return arrives — high-volatility slots pay rarely and larger, low-volatility slots pay often and smaller. Neither makes a game due a win.
On the betting side, the adjacent offering is usually a full sportsbook plus esports markets, covering pre-match and in-play prices, accumulators, bet builders and cash-out. Sports free bets carry their own conditions, most commonly minimum qualifying odds around 1.50 to 2.00 in decimal terms, and a shared wallet means casino wagering and sports wagering may contribute differently to the same bonus. Game contribution is worth checking whichever side you play: slots often count fully, table games and live dealer much less, and some titles not at all.
Who may use these sites, and what protection applies
You must be 18 or over. The casinos on this page hold overseas licences, typically Curaçao, rather than a UK Gambling Commission licence. That distinction is the whole subject of the site: a Curaçao licence permits the operator to run a gambling business under that regulator's rules, and accepting British customers is not the same thing as being authorised by the Commission to serve the British market. UKGC protections — GAMSTOP integration, the credit card ban, UK deposit-limit and advertising rules, and access to the Commission's approved dispute resolution services — do not apply to an offshore operator. GAMSTOP itself covers Great Britain-licensed sites; self-exclusion there does not reach a Curaçao casino.
The practical consequences: your recourse in a dispute is whatever the operator's own terms and its overseas regulator provide; responsible-gambling tools vary by site rather than being mandated; and you remain responsible for checking that a site is open to UK residents at all, since some restrict British customers without saying so prominently. Tax on winnings is not levied on the player in the UK, but that does not make an offshore account risk-free.
If you registered with GAMSTOP because you needed to stop, playing at a site outside it defeats the purpose. Free help is available from GamCare and the National Gambling Helpline, 24 hours a day, and blocking software plus a bank-level gambling block will do more than willpower. Our responsible gambling guidance sets out the options, and our terms of use explain the limits of what this site publishes.
Before you write to us
- Name the page on calcgenie.com and quote the sentence you are querying.
- Say which casino and which offer, since terms differ between markets and change over time.
- For a factual correction, include a link or document we can verify — we publish corrections, dated, when a claim turns out to be wrong.
- For an account or payment problem, tell us what the casino has already said, so we can point you at the right next step rather than the first one.
- Do not send passwords, full card numbers or copies of identity documents. We never need them.
Our information was last fact-checked on 23 September 2026 by Cecil Langton. Bonus percentages, caps and payment availability move faster than any review cycle, so treat everything here as a starting point and confirm the current terms with the operator. If something on the page no longer matches what you see in the cashier, that message is genuinely useful to us — send it.
