Contact Us
You can reach the editorial team at [email protected]. That address handles corrections, questions about how we rank the highest payout casinos not on GamStop, feedback on a casino you have used, and press or partnership enquiries. We aim to reply within two working days, and we read everything even when a reply takes longer.
Before you write, it helps to know what we are: Non Gamstop Casinos is an independent comparison and research site, not a casino, not a payment processor and not a regulator. We cannot access your account, release a withdrawal, verify your documents or overturn a decision made by an operator. What we can do is explain the terms, point you at the right complaints route, and correct our own pages when they are wrong.
Which enquiry goes where
| What you need | Who to contact | What to include |
|---|---|---|
| A stuck withdrawal, a closed account, a voided bonus | The casino's own support first, then its licensed complaints or ADR route | Your account ID, dates, amounts in GBP, screenshots of the terms you were shown |
| A factual error on one of our pages | Us, at [email protected] | The page address, the line you are disputing and, ideally, a source |
| Feedback on a casino you have used | Us | Casino name, what happened, rough dates — we do not publish personal details |
| Help with gambling that has stopped being fun | GamCare's National Gambling Helpline, free on 0808 8020 133, 24 hours a day | Nothing. You do not need an account, a reference or a reason |
| Blocking access to gambling sites | GAMSTOP for GB-licensed sites, plus device-level blocking software | See our responsible gambling guidance |
How we make money, stated plainly
Some of the casino links on this site are commercial. If you open an account through one, we may earn a commission at no extra cost to you. That arrangement does not buy a position in our tables and it does not soften a review. Where an operator declines to answer our questions about withdrawal limits or verification, we say so on the page rather than quietly dropping the subject. If you think a page reads like an advert rather than research, tell us — that is exactly the feedback we want.
Questions we get most about payouts
Most contact about the highest payout casinos not on GamStop falls into a handful of themes. Here is the short version of each, so you can see whether you still need to email.
"Why hasn't my withdrawal arrived?"
Nine times out of ten it is one of four things: identity verification is incomplete, a source-of-funds check has been raised, a bonus is still carrying wagering requirements, or the payout is queued behind a weekly or monthly withdrawal limit. Offshore casinos commonly cap cashouts per week and per month, and a large jackpot win may be paid in instalments against that cap. Read the terms attached to the specific bonus you claimed before assuming something has gone wrong, then contact the casino's support with your account reference.
"Is this site licensed to take my money?"
Casinos outside the GAMSTOP scheme are not licensed by the UK Gambling Commission. They typically hold an overseas licence — Curaçao is the most common — issued to a company registered outside Great Britain. Accepting British customers is not the same as being authorised to serve them. The practical consequence is that the Gambling Commission's consumer protections, its complaints escalation and its rules on bonus fairness and advertising do not apply to you at these sites, and neither does GAMSTOP self-exclusion. Anyone using them must be 18 or over, and you should check the operator's own terms for whether UK residents are accepted at all, because some overseas brands restrict Great Britain while still accepting other parts of the UK.
"Can you get me a bonus that isn't listed?"
No. We publish the headline offers operators advertise and nothing more. We do not hold private codes, we cannot negotiate terms on your behalf, and we will not describe a deposit-matched bonus as free money, because every one of them requires your own stake first.
The casinos readers ask about most
Three names dominate our inbox, so it is worth setting out what is actually on offer and where each one is weaker. Ratings below are our own editorial scores, not customer review averages.
Betmica — the largest advertised package on our list
Betmica sits at the top with an editorial rating of 10.0 largely because its headline welcome offer, 570% up to £5,700 plus 270 free spins, is quoted in pounds rather than euros — which matters, because a GBP-denominated account removes the currency conversion spread you otherwise pay on every deposit and withdrawal. Readers asking about maximum payout potential usually land here first.
The limitation is the arithmetic. A percentage match that large only reaches its ceiling with a very substantial deposit, and the bonus funds arrive attached to wagering requirements, maximum bet caps while a bonus is active, and an expiry date. Check the cashout cap on bonus-derived winnings before you decide the headline figure is meaningful to you.
Kikibet — a middle-sized match with a heavy spins component
Kikibet (9.8) pairs 350% up to £5,555 with 300 free spins, and the spins allocation is the reason readers mention it. Spins are usually released in daily tranches on a named slot rather than all at once, and winnings from them typically carry their own wagering multiplier separate from the deposit match.
Its weakness for payout-focused players is the same one that affects most offshore brands: withdrawal ceilings and verification timing are set in the terms, not by the size of your win, and we have not been able to independently confirm processing times beyond what the operator advertises. Treat advertised withdrawal speeds as claims until you have been through verification yourself.
Betninja — a flat cash figure instead of a percentage
Betninja (9.8) advertises £1,000 in bonus funds and 100 free spins to all new players. We include it because a fixed-ceiling offer in sterling is far easier to evaluate than a four-figure percentage: you can work out the qualifying deposit and the total wagering obligation without guesswork, which suits readers who want predictability over headline size.
The trade-off is obvious — the maximum available is a fraction of what Betmica or Rivo advertise, so high-stakes players will find the ceiling low. As with every entry here, "to all new players" still means one account per person, household and IP address, subject to eligibility checks.

All offers are as advertised by the operator and subject to that operator's terms, including wagering requirements, minimum deposits, maximum bonus bets, expiry dates and cashout limits. Offers in euros or dollars will be converted at your bank's or e-wallet's rate. Full detail sits on our non GamStop casino comparison.
Money in, money out — what to check before you email us
Payment questions are the single most common reason readers get in touch, so here is the general shape of it. We do not publish a payment list for any individual brand unless the operator confirms it, because availability for British customers changes without notice.
- Minimum deposits. Usually the gate on a welcome offer. A 570% match means nothing if your deposit sits below the qualifying threshold.
- Debit cards. Widely accepted, though UK-issued cards are sometimes declined by the issuing bank for offshore gambling merchants. A decline is not necessarily the casino's doing.
- Bank transfers. Slower, often used for larger withdrawals, and the method most likely to trigger source-of-funds questions.
- E-wallets. Typically the fastest payout route once verification is complete. PayPal availability at offshore casinos is limited and should never be assumed — check the cashier before depositing.
- Cryptocurrency. Common at these sites and quick, but it introduces price volatility and network fees, and it sits entirely outside UK consumer protection.
- Fees and conversion. The casino may charge nothing while your bank still applies a conversion spread on a euro or dollar account. That cost is invisible in the headline offer.
- Withdrawal limits. Per transaction, per week and per month. This, not processing speed, is what usually decides how quickly a large win actually reaches you.
Expect KYC before your first payout: photo ID, proof of address and, for larger sums, evidence of where the funds came from. Providing documents promptly is the fastest thing you can do to speed up a withdrawal.
What these sites actually offer
If your question is about range rather than payouts, the categories break down roughly like this. Slots dominate — video slots from a mix of established and newer software providers, with return to player (RTP) percentages and volatility levels that determine whether wins come often and small or rarely and large. Progressive jackpot titles pool stakes across operators and pay the largest prizes, though jackpot wins are frequently paid in instalments under the casino's withdrawal cap.
Table games cover blackjack, roulette and baccarat in RNG form, usually with lower house edges than slots and often a reduced contribution to wagering requirements — sometimes 10%, sometimes zero. Live dealer rooms stream real tables and typically contribute least of all to bonus wagering, which catches out a lot of players. Mobile play is browser-based at most of these brands rather than app-based.
The sportsbook side
Most of the casinos listed here also run a sportsbook, and several share a single wallet between casino and betting. That sounds convenient, but it means a casino bonus balance can restrict what you do on the sports side until wagering is cleared. Sportsbooks generally carry pre-match and in-play markets, accumulators, bet builders, cash-out and a growing esports section. Sports free bets are governed by minimum qualifying odds — commonly around 1.50 in decimal terms — and the stake is not usually returned with the winnings. Casino bonus terms and sportsbook bonus terms are separate documents; read whichever applies to the offer you are claiming.
How we research these pages
- We read the published terms and conditions for each advertised offer and record the wagering multiplier, minimum deposit, maximum bonus bet, expiry and cashout cap.
- We check the licensing details the operator publishes, and note where a licence is overseas rather than issued by the UK Gambling Commission.
- We verify which payment methods and account currencies the cashier shows for British customers rather than assuming sterling is available.
- We weigh withdrawal limits and verification requirements alongside the headline offer, because a large bonus behind a low weekly cap is not a high payout in practice.
- We re-check pages on a rolling basis. This one was last fact-checked on 26 September 2026 by Jennifer Watts.
We have not deposited at, played at or withdrawn from any of these operators. Everything here is desk research on published sources and operator disclosures, and we say so rather than implying hands-on testing. More on our approach sits on our about page, and the legal basis for using the site is set out in our terms.
Who can use these sites, and who should not
You must be 18 or over. If you have registered with GAMSTOP, that self-exclusion covers operators licensed in Great Britain for the period you chose — six months, one year or five years — and it does not extend to overseas sites. Deliberately seeking out casinos outside that scheme while excluded defeats the protection you put in place, and we would rather you spoke to GamCare on 0808 8020 133 than to us. Blocking software at device or bank level is the more effective backstop when a self-exclusion alone is not holding.
No casino is completely safe, no withdrawal is guaranteed, and gambling is not a way to make money or fix a financial problem. If any of that is in play, close the tab.
