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 we are, how the rankings on sdcpb.com are put together, how we are paid, and — just as importantly — what our reviews cannot tell you. Last fact-checked 23 September 2026.
We are not a casino and not a betting operator. We take no deposits, hold no player funds and settle no bets. We read terms and conditions, check licence claims against public registers where those registers exist, and write up what we find in plain English.
Why this site exists
GamStop is the free self-exclusion scheme for online gambling operators licensed by the UK Gambling Commission. Once you register, every GB-licensed site must refuse you an account for the exclusion period you chose — six months, one year or five years — and it cannot be lifted early. Non GamStop casinos sit outside that system because they hold overseas licences instead of a Great Britain one, most commonly from Curaçao or Anguilla.
That distinction matters far more than most marketing pages admit. Accepting British customers is not the same as being authorised to serve them. An operator without a UKGC licence is not covered by UK consumer gambling protections, is not bound by GB advertising rules, and cannot be escalated to a UKGC-approved alternative dispute resolution body. If you registered with GamStop because gambling had become a problem, the right response is to let the exclusion run, not to look for a way around it. Our responsible gambling page lists the UK support services worth contacting first, including GamCare.
Readers who are outside GamStop and simply comparing overseas sites deserve accurate information rather than a wall of bonus percentages. That is the gap this site tries to fill.
How we are funded, in plain terms
Non Gamstop Casinos earns commission when a reader follows a link to an operator and opens an account. That is the whole business model. Two things follow from it that you should hold us to:
- Commercial relationships do not buy a position. Rank order and editorial scores are set before commercial terms are discussed, and an operator cannot pay to be moved up or to have a criticism removed.
- Commission is not free money for you. Every offer on this site requires you to deposit and wager your own funds, and most of the value advertised is locked behind wagering requirements you may never clear.
We would rather lose a click than describe a site as safe. No casino is completely safe, no withdrawal is guaranteed, and gambling is not a way to make money or to fix a financial problem.
What we check before a casino appears on the list
Our assessments are desk research and document review, not play-testing. We do not open accounts, deposit, play or withdraw, and we never present advertised speeds as measured ones. The criteria below carry the most weight, in roughly this order:
- Licence and ownership. Which jurisdiction issued the licence, which company is named on it, and whether that company can be identified in the site's own terms. Vague or absent ownership details are a serious mark against a site.
- Bonus terms, not bonus headlines. Wagering multiple, whether it applies to bonus only or deposit plus bonus, game contribution rates, maximum bet while a bonus is active, expiry window and any cap on what you can cash out.
- Payments for British customers. Whether GBP accounts exist, which debit card, bank transfer, e-wallet and cryptocurrency routes are actually available at sign-up, and where conversion costs or processing fees land.
- Withdrawal conditions. Stated processing times, daily, weekly and monthly limits, and how KYC identity checks and source-of-funds requests are described.
- Games and providers. The named software studios behind the slots and live tables, and whether RTP information is published anywhere the player can find it.
- Support and complaints. Contact channels, stated hours, and what route exists if a dispute is not resolved internally.
Ratings on sdcpb.com are editorial scores from that framework. They are not customer review averages and should not be read as one. Terms change without notice, so verify anything material on the operator's own pages before you register.
Three operators, and what our research method actually surfaces
The write-ups below show the kind of reading we do. They are examples of method rather than endorsements.
Betmica — the biggest headline number, and the most terms to read
Betmica leads our list on editorial score because its published bonus structure and payment options were the most completely documented of the sites we reviewed, which makes it easier for a reader to work out what they are agreeing to. The advertised welcome offer is 570% up to £5,700 plus 270 free spins, which is a multi-deposit package rather than a single match — you would need to fund the account repeatedly to reach anything near the maximum, and the qualifying deposit, wagering multiple, per-spin bet cap and expiry all apply. Limitation: a percentage that large exists because the wagering attached to it is substantial, and most players clear a fraction of it at best. Treat the £5,700 as a ceiling almost nobody reaches.
Kikibet — a simpler package, still capped
Kikibet is here because its offer is more legible: 350% up to £5,555 and 300 free spins, quoted in pounds, which is useful if you want to avoid currency conversion. Free spins of that volume are typically released in daily tranches on named slots rather than all at once, and winnings from them usually carry their own wagering and a cashout cap. Limitation: we could not verify a published maximum withdrawal figure to sit alongside the headline, so check the cashout limit in the bonus terms before depositing — it is the single number that decides whether a large win is payable.
Betninja — a flat figure rather than a percentage
Betninja earns its place for a different reason: the offer is a straightforward £1,000 bonus and 100 free spins for all new players, with no stacked percentage to decode. For readers who find multi-tier packages confusing, that clarity has real value. Minimum deposit, wagering, game contribution and maximum bet rules still apply. Limitation: a flat headline can still hide a low cashout cap or a short expiry window, and a simpler bonus is not automatically a better-value one once you compare the wagering multiple.

Where an offer is quoted in euros or dollars, expect a conversion cost on every deposit and every withdrawal unless the site opens a genuine GBP account for you. That spread is easy to overlook and it compounds. Full reviews sit on our non GamStop casinos comparison page.
Money in, money out — what we always check
Costs start at the minimum deposit, which on overseas sites is commonly a small fixed amount but is often higher for a bonus to qualify. Beyond that:
- Debit cards are the most familiar route for British players, but UK-issued cards are sometimes declined by the issuer on overseas gambling merchants. Credit cards cannot be used for online gambling by GB-licensed operators; overseas sites vary, and paying to gamble with borrowed money is a poor idea regardless.
- Bank transfers are usually the highest-limit option and the slowest, with several working days common and intermediary bank fees possible on international payments.
- E-wallets are typically the quickest withdrawal route. PayPal is rare outside the GB-licensed market, so do not assume it is available — check the cashier before you register.
- Cryptocurrency appears widely on non GamStop sites. It removes card declines but adds network fees and price volatility, and converting back to sterling is a separate cost.
Withdrawals are where most complaints originate. Identity verification (KYC) is standard and should be completed early rather than at cash-out; source-of-funds requests for larger sums are normal and legitimate. Note any daily, weekly or monthly withdrawal cap, and note whether bonus winnings are capped separately. If a payout stalls, put the complaint in writing through the operator's own procedure first — without a UKGC licence there is no UK ombudsman route behind it.
What these sites offer beyond slots
The casinos we cover typically run several product lines from one account: slots including progressive jackpot titles, RNG table games such as blackjack, roulette and baccarat, and live-dealer studios streaming those same tables with human croupiers. Slot volatility and published RTP are the two figures worth checking before you play anything. Most sites also carry a sportsbook alongside the casino, usually on a shared wallet, covering pre-match and in-play markets, accumulators, bet builders, cash-out and esports, with free bets that carry minimum qualifying odds — often around 1.50 in decimal terms. Sportsbook bonuses and casino bonuses almost never share wagering rules, so read them separately.
Who may use these sites
You must be 18 or over. Non GamStop casinos hold overseas licences and are not authorised by the UK Gambling Commission, which means GB consumer protections, GamStop self-exclusion and UKGC dispute resolution do not apply to them. Anyone currently self-excluded through GamStop should not seek an alternative route to gamble. Blocking software and bank gambling blocks are more useful tools at that point, and GamCare's National Gambling Helpline is free and confidential on 0808 8020 133, 24 hours a day. The full terms of use for this site set out our editorial and legal position.
Corrections and contact
Editorial content here is written and maintained by Keith Mowbray. Bonus terms, payment options and licence details change often, and we would rather be told we are out of date than leave an error standing. If something on sdcpb.com looks wrong, send us the detail and we will re-check the source and amend the page.
If you are deciding where to start: compare the wagering multiple and the cashout cap before the headline percentage, prefer a site that will hold your balance in pounds, and read the withdrawal section of the terms before the bonus section. That order will tell you more in five minutes than any rating on this site.
