Non GamStop casinos: what this guide covers

Non GamStop casinos are online casinos that are not licensed by the UK Gambling Commission and so do not take part in GAMSTOP, Great Britain's national self-exclusion scheme. Most hold licences from other jurisdictions. This guide covers ten casinos not on GamStop in the order supplied by the publisher, with the licences, bonuses, payments, games and controls that decide whether one suits you. Links to operators on this page are commercial links.

The information was last fact-checked on 29 September 2026. Bonus terms change often, so confirm the current conditions on each operator's own site before depositing. Nothing here is a guarantee of winnings or withdrawals, and the Responsible Gambling page explains the tools and support available.

Best non GamStop casinos reviewed in ranked order

The ten write-ups below follow the publisher's ranking and describe the offers exactly as supplied. The ranking and ratings are editorial and are not independent measurements of payout speed or safety. For most operators we do not have confirmed data on launch year, game count, payout time, wagering or licensing, so the tables mark those items as Not confirmed instead of guessing. Check the cashier and bonus terms of any site before you rely on them.

Each review opens with the feature that matters most for that casino when comparing UK casinos not on GamStop, such as currency, size of offer or type of reward.

1. Betmica: the largest sterling headline offer

Betmica leads the list with a welcome offer of 570% up to £5,700 plus 270 free spins, and it is one of the few in the top ten where the headline is priced in pounds. That matters for a British reader because it points to a sterling-denominated offer, which can reduce conversion costs if the cashier also holds a GBP balance. That still needs confirming at registration.

A 570% match is unusually large, and large matches often carry heavier conditions. To get the maximum you would need to deposit £1,000 at 570%, so check whether the offer is split across several deposits, how wagering is calculated and whether there is a cashout cap. We have no confirmed wagering figure, so the offer should not be judged on size alone.

Evidence is also thin on licence, ownership and withdrawal speed. Confirm those before depositing.

Pros

• Headline offer priced in pounds sterling
• Large match percentage with free spins included
• Top editorial rating in this list

Cons

• Wagering, cashout cap and expiry not confirmed
• Licence and ownership details not supplied
• A very large match can hide restrictive terms

2. Kikibet: sterling match with a big free spins allowance

Kikibet offers 350% up to £5,555 and 300 free spins. The 300 spins are the notable feature, since free-spin bundles are normally released in daily or per-deposit batches and each batch may have its own wagering. That is the first thing to read in the terms.

The match is smaller than Betmica's percentage but the cap is close, which means you would need a smaller deposit to reach the maximum. The offer text is written in a different currency format from most brands (£ after the figure), so read the cashier to confirm the balance is actually held in pounds.

We have no confirmed information on game contribution, maximum stake or cashout limits.

Pros

• Sterling headline offer
• 300 free spins alongside the match
• High cap reachable with a smaller deposit than Betmica

Cons

• Spin release schedule and wagering not confirmed
• No confirmed licence or complaint route in the supplied information
• Payout time unknown

3. Betninja: a flat bonus for every new player

Betninja advertises a £1,000 bonus and 100 free spins to all new players. Unlike a percentage match, this is described as a fixed sum, so it is worth finding out whether the £1,000 is one credit or a total across deposits. The wording "all new players" suggests no code, but we cannot confirm any qualifying deposit.

A fixed figure is easier to model. If the bonus were, say, 40x on the bonus alone, £1,000 would require £40,000 of wagering, which is out of reach for most casual players. Always check the multiplier first.

The name also suggests a betting product, but we have no supplied evidence that Betninja offers a sportsbook, so confirm before assuming.

Pros

• Fixed sterling bonus that is easy to understand
• Open to all new players on the offer wording
• 100 free spins included

Cons

• Qualifying deposit and wagering not confirmed
• Sportsbook availability not confirmed
• Licence details not supplied

4. WinnerIsland: euro pricing and the conversion question

WinnerIsland's welcome bonus is up to €1,000 plus 100 free spins. It is the most modest headline of the ten, but the more important point for British readers is currency. A euro offer suggests a euro-based account, so deposits from a sterling debit card or bank may incur exchange charges from your bank or the casino.

The value of this offer therefore depends on whether a GBP wallet is offered. If not, convert both ways in your head: a £200 deposit may become roughly €230 on a given day, and the same conversion applies again on withdrawal. Actual rates and fees vary.

A smaller cap is not a drawback in itself. Smaller bonuses often carry less demanding rollovers, but that has not been confirmed here.

Pros

• Smaller headline may come with more manageable terms
• 100 free spins included
• Clear cap on the bonus

Cons

• Euro pricing may mean currency conversion for UK players
• Wagering and expiry not confirmed
• GBP account availability not confirmed

5. Zombillion: a multi-deposit pack in pounds

Zombillion offers a welcome pack of 250% up to £4,000 plus 200 free spins. "Pack" usually means the bonus is spread over several deposits, so the maximum may require more money than a single top-up. Confirm how many deposits qualify and whether each has its own wagering and expiry.

The offer is in sterling, and 200 spins is a mid-sized allowance. If the spins are attached to specific slots, check the spin value and whether your winnings carry wagering.

Evidence on games, providers and payments is not supplied, so we cannot say what the lobby looks like.

Pros

• Sterling welcome pack
• 200 free spins included
• Mid-sized cap that is easier to plan around

Cons

• Number of qualifying deposits not confirmed
• Wagering and cashout limits not confirmed
• Game and provider information not supplied

6. Smash Casino: a slots-only package in euros

Smash Casino presents 600% up to €10,000 as a slots welcome package. The important word is slots. A package aimed at slots can exclude table games and live casino, or count them at a low rate, so it suits players who plan to play slots not on GamStop rather than roulette or blackjack.

The cap of €10,000 is the joint highest in the list, but to claim near the top you would need a deposit of roughly €1,667 at 600%. Bonuses at that scale can mean very large wagering totals, so decide how much you would deposit before looking at the maximum.

As with WinnerIsland, euro pricing raises the currency conversion question for a sterling account.

Pros

• Offer clearly aimed at slot players
• Very high cap
• Package format may allow staged claims

Cons

• Slots-only offer limits use for table game fans
• Euro pricing may add conversion costs
• Wagering and stake limits not confirmed

7. Nightluck: a layered bonus that needs decoding

Nightluck's listing reads €6,400 + 280 FS + 805%. It is a compressed description: a percentage, a euro cap and free spins. The exact structure, such as which deposit earns which percentage, is not stated, so this is the offer that most needs the full terms read before you deposit.

The 805% figure is the highest percentage in the list. A very high percentage on a small deposit gives a large bonus balance that you must wager, so the effective risk may be greater than the figure suggests.

The currency is euro, so the same conversion caution applies as with WinnerIsland and Smash Casino.

Pros

• Highest bonus percentage among the ten
• 280 free spins included
• Sizeable overall cap

Cons

• Offer structure is unclear from the listing
• Euro pricing may add conversion costs
• Wagering and expiry not confirmed

8. CoinPoker: the dollar offer and a crypto-leaning profile

CoinPoker offers 150% up to $2,000. It is the only one of the ten priced in US dollars, which for a British player almost certainly means conversion whichever way you pay, unless you use crypto or a stablecoin. The brand name suggests a cryptocurrency and poker focus, but we have no supplied evidence to confirm the products or coins supported.

The 150% match is the smallest percentage in the list. A more modest bonus can suit someone who wants a workable rollover rather than a very large balance, though that depends on terms we do not have.

Cryptocurrency values can move between deposit and withdrawal, and a payout is only worth what the coin is worth when you convert it to pounds.

Pros

• Modest match percentage that may be easier to manage
• Clear dollar cap
• May suit players comfortable with crypto payments

Cons

• Dollar pricing means conversion for GBP users
• Product range and supported coins not confirmed
• Crypto values can change before you cash out

9. Rivo: the only listing with cashback attached

Rivo combines a slots welcome package of 1000% up to €10,000 with 25% cashback. Cashback is the distinguishing feature: it is a reward on losses, usually paid as bonus funds or cash, and the terms decide its value. Look at whether it is calculated on net losses, over what period and whether it carries wagering.

As an illustration only, 25% cashback on £200 of net losses would return £50. If that £50 is paid as a bonus with 10x wagering, you would need to stake £500 before withdrawing. Rivo's actual terms are not supplied.

The welcome package is another slots-focused offer in euros, so the currency and game restriction points apply.

Pros

• Cashback offer alongside the welcome package
• Very high cap for slot players
• Highest match percentage in the list

Cons

• Cashback conditions not confirmed
• Euro pricing may mean conversion
• Package is aimed at slots

10. Daytonaspin: a sterling match with matching free spins

Daytonaspin closes the list with 255% up to £4,500 and 255 free spins. The matching number for percentage and spins is a straightforward structure, and the offer is priced in pounds, which helps with currency clarity.

The rating is the lowest of the ten at 9.7, but the gap is small and shows an editorial preference, not a measured difference in reliability. For a player who wants a sterling offer with a mid-sized cap, it belongs in the comparison.

As with the others, wagering, cashout caps and licence information are not confirmed.

Pros

• Sterling offer with simple structure
• 255 free spins included
• Mid-sized cap

Cons

• Wagering and expiry not confirmed
• Licence and complaint route not supplied
• Payout speed unknown

What are casinos not on GamStop?

GAMSTOP is a free service that lets people in Great Britain exclude themselves from online gambling with every operator licensed by the UK Gambling Commission. A non GamStop casino does not take part in it. The label describes participation in a scheme, and nothing else about the casino.

These sites are usually described as offshore casinos, meaning they are licensed and based outside Great Britain. Many accept British customers. That is not the same as being authorised to serve them: a casino can accept a UK registration, a sterling deposit or a UK card without holding a UKGC licence.

The label does not tell you about ownership, fairness, payout record or whether identity checks apply. It also does not mean no verification. Sites that advertise "no KYC" are making a claim about when checks happen, and payment providers and licensing rules can still require documents later. If you have registered with GAMSTOP, using a casino outside the scheme undermines the protection you asked for. See the section on self-exclusion below.

The safest way to read the phrase is as a starting fact. Then check the licence, entity, terms and controls, which is what the rest of this guide sets out.

How non GamStop casinos differ from UKGC-licensed UK casinos

UK casinos licensed by the UKGC must meet licence conditions on customer protection, advertising, fair terms and anti-money-laundering. Those rules apply to services offered in Great Britain. Northern Ireland has its own legislation, so the position there is not identical.

The practical benefits of an overseas casino are usually larger headline bonuses, more payment options and fewer restrictions on some game features. The limitations are weaker routes to redress, a lack of GAMSTOP protection and terms that are harder to challenge.

These are general patterns, not statements about any single site. Some overseas regulators are demanding and some operators behave well, while others do not. The differences show up in the details: whether the licence can be verified, whether the terms are clear and whether disputes have been handled fairly.

How we reviewed these non GamStop casinos

The ranking and ratings are supplied by the publisher and the page draws on the published offer information supplied to us. We did not carry out deposits, withdrawals or support tests, and we do not claim to have. Where an item has not been confirmed we say so. The About Us page gives more on the site's approach.

The criteria we use, and that readers can apply themselves, are:

• Ownership: is a company named in the terms, and does the name match the licence entry?
• Licence verification: does the licence check out against the licensing body's own register for the exact domain?
• Clear terms: are wagering, maximum stake, expiry and cashout limits stated in plain language?
• Complaint patterns: do reports show unresolved payout disputes?
• Customer support: is there a documented channel, and does it answer in writing?
• Account controls: are limits, time-outs and self-exclusion documented?

New casinos not on GamStop: what a short track record means

New casinos not on GamStop come in two kinds. A new brand from an established company may share management, software and payment processing with older sites. A new online casino company has no operating history at all, so there is nothing to show how it treats large withdrawals.

Look at how long the domain has been active, whether the operator is named, and whether the terms match those of a known group. A limited track record is not a fault in itself, but it means fewer data points.

Specific red flags include:

• no named operating company or licence number
• a licence claim that cannot be matched to the exact domain
• terms that change after registration
• unusually high bonuses with no stated wagering
• pressure to deposit again to release a withdrawal
• support that only replies through chat with no written record

Common licences behind Curaçao casinos not on GamStop and other overseas sites

Online casino authorisation is the permission a regulator gives an operator to offer games. For Great Britain, the relevant permission is a UKGC licence. Any other licence is foreign, and it shows the operator satisfies that jurisdiction, not that it is authorised for British customers.

Two checks matter most. First, look up the licence on the regulator's own register, matching the exact domain. Second, match the legal entity in the terms with the licence holder. A badge in the footer is not proof.

Consumer protections and complaint routes depend on the regulator. Some accept player complaints and can order action, some only act on serious breaches and some offer little in practice. Read what the operator says, then confirm it with the regulator.

• Curaçao: the most common licence for Curaçao casinos not on GamStop. The jurisdiction has been reforming its regime, so check whether a licence is current and who holds it.
• Panama: a licence that is common among smaller operators, with limited public complaint handling.
• Malta: the Malta Gaming Authority is generally regarded as more demanding and has a formal complaint process, but a Maltese licence does not by itself authorise service in Great Britain.
• Estonia: licences are issued by the national tax and customs authority and are mostly aimed at operators serving the Estonian market.
• Anjouan: an offshore licence from the Comoros islands, sometimes used by newer brands, with limited public oversight information.
• Tobique: the Tobique Gaming Commission is linked to a First Nation in New Brunswick, Canada, and relatively few operators use it.
• Kahnawake: the Kahnawake Gaming Commission operates in a Mohawk territory in Canada and has a long history, including a dispute process.

These descriptions are general. We do not have supplied licence details for any of the ten casinos, so confirm the licence on each site.

Casino bonuses at non GamStop casinos

Casino bonuses are the main draw of overseas sites, and also the biggest source of confusion. The percentage on the card is only one term. The wagering requirement, game contribution, maximum bet, expiry and cashout limit determine what you can actually withdraw.

Welcome bonuses

A welcome bonus is a reward for a first deposit or for the first few deposits. The ten offers here range from 150% (CoinPoker) to 1000% (Rivo). Higher does not mean better. Check the qualifying deposit, whether the bonus is split and whether it is restricted to slots.

Wagering can be calculated on the bonus only, or on deposit plus bonus. Take a £100 deposit with a £100 bonus at 35x:

• Bonus only: £100 × 35 = £3,500 to wager
• Deposit plus bonus: £200 × 35 = £7,000 to wager

These are illustrative figures, not the terms of any casino listed.

Free spins

Free spins are plays on chosen slots at a fixed value. 100 spins at £0.10 are worth £10 in total, though the spin value and any wagering on the winnings differ between sites. Spins may be released in batches over several days and may expire if unused. Most offers here bundle spins with a match, as with Kikibet's 300 or Zombillion's 200.

No-deposit bonuses

A no-deposit bonus is credited without you paying in. None of the ten offers supplied is a no-deposit bonus. Where casinos do offer them, they usually carry a low cashout cap and high wagering, and may need identity verification before withdrawal. Treat them as a way to look at the site, not as free money.

Cashback bonuses

Cashback returns a percentage of losses. Rivo lists 25% cashback. Check whether it is paid as cash or bonus funds, whether it is on net losses and whether wagering applies. For example, if £200 net losses returned £50 as a bonus with 10x wagering, you would need to stake £500 before it could be withdrawn.

Loyalty rewards

Loyalty rewards give points, levels or perks based on activity. Nothing in the supplied information describes any loyalty scheme for the ten casinos, so we cannot compare them. When you read a programme, look at how points convert, whether perks carry wagering, and whether levels can drop.

The conditions that decide value

• Game contribution to wagering: slots often count 100%, while table games or live games may count 10% or nothing. £1,000 staked on a 10% game only adds £100 to the requirement.
• Maximum bonus bets: a cap such as £5 per spin while a bonus is active. Breaking it can void winnings.
• Bonus expiry dates: often 7 to 30 days, but this is a generalisation.
• Bonus cashout limits: a cap on what bonus winnings can be withdrawn.
• Deposited money: check whether your cash is used before bonus funds, and whether you can withdraw it if you forfeit the bonus.

The Terms and Conditions of this site cover its own use. The bonus terms that apply are always those on the operator's site.

Payment methods, GBP accounts and Paysafe casinos not on GamStop

Deposits and withdrawals are not the same. A method that accepts your deposit may not be available for withdrawal, and the method you used to deposit often has to be used for the payout. A method being common in Britain does not mean a given casino supports it, and we have no supplied payment lists for the ten operators. Check the cashier before you register.

A GBP account means your balance is held in pounds. If the balance is in euros or dollars, your bank or the casino will convert each payment, sometimes with a fee and a less favourable rate. Casinos priced in pounds in this list are Betmica, Kikibet, Betninja, Zombillion and Daytonaspin. Casinos showing euros or dollars are WinnerIsland, Smash Casino, Nightluck, Rivo and CoinPoker.

Debit card payments

Debit cards are familiar and simple. Some British banks block payments to gambling sites without UK licences, and foreign-currency payments may attract a fee. Credit cards are banned for gambling with UKGC-licensed operators, but overseas sites are outside that rule. Even so, gambling with borrowed money is a risk to think about carefully.

Bank transfers

Bank transfers suit larger sums but tend to be slower. There may be a minimum, and the casino may need to match the name on the account with yours. They are among the slowest ways to receive a payout.

E-wallets

E-wallets such as Skrill and Neteller can be quick, and keep card details from the casino. Some casinos exclude e-wallet deposits from bonuses. Check this before depositing.

PayPal availability

PayPal is widely used in the UK, but it is far more usual at UKGC-licensed sites. We have no evidence that any casino in this list accepts it for British customers, so do not choose a site on the assumption it does.

Prepaid vouchers and Paysafe

Paysafe casinos not on GamStop take Paysafecard prepaid vouchers, which are good for budgeting because you can only spend what you bought. They are normally deposit-only, so you will need another method to withdraw. No supplied evidence confirms which of the ten accept it.

Cryptocurrency payments

Crypto payments are common at overseas casinos and can be fast once approved. The risks are price swings, network fees, irreversible errors if you send to the wrong address and capital gains implications in some circumstances. CoinPoker's dollar pricing and name point in this direction, but no supplied information lists supported coins.

Fees, minimums and currency conversion

Minimum deposits are not confirmed for any of the ten casinos. Fees can come from the casino, the payment provider or your bank. On a £200 deposit, a 3% conversion charge is £6, and it can apply again when you withdraw.

Withdrawals, KYC and restrictions at gambling sites not on GamStop

Withdrawal time has two parts. The first is casino approval, sometimes called the pending period, when the operator reviews the request and any documents. The second is payment settlement, when the money moves through the card network, bank or crypto network. A casino that approves in hours may still take days to settle by card.

Non GamStop does not mean no verification. Identity checks for age and address are typical, and larger withdrawals may trigger source-of-funds checks, where the operator asks for evidence of where the money came from, such as payslips or bank statements. This is a normal anti-money-laundering step, not proof of bad faith.

Other points that affect timing include:

• Withdrawal limits: daily, weekly or monthly caps that can slow a big win into instalments.
• Bonus restrictions: you may not be able to withdraw until wagering is finished, and a withdrawal may cancel the bonus.
• Method matching: payouts commonly go back to the deposit method.
• Document quality: blurry or expired documents cause the most avoidable delays.

We do not have confirmed payout times for any of the ten, and no casino can guarantee an instant withdrawal. Complete verification early, because it often takes longer than the payment itself.

If something goes wrong, keep all messages, contact support in writing, and use the operator's complaints procedure. Then go to the licensing body if it accepts player complaints. Outside the UKGC there is no approved UK dispute service, so the remedy may be limited. For a withdrawal dispute, do not send more deposits to unlock funds. If you need to reach us about this site, use Contact Us.

Slots not on GamStop and other games not on GamStop

Games not on GamStop are the same kinds of games that appear at other casino sites, but the feature set may differ. Overseas casinos can offer bonus buys, turbo spins and higher stakes that UK-licensed sites restrict. That is a point about features, not about quality.

Slots not on GamStop

Slots are the biggest category, and they are the focus of offers like Smash Casino's and Rivo's packages. Popular titles that often appear at online casinos include Book of Dead, Starburst, Gates of Olympus, Sweet Bonanza and Big Bass Bonanza. We have no evidence that any given title is at any of the ten casinos, so check the lobby.

Three things to understand:

• Return to player (RTP): the long-run percentage a game pays back. A 96% RTP means £96 per £100 staked over a very large number of spins, not in a session.
• Version-specific RTP: the same slot can be released at different RTPs, and the casino picks which. Check the game info screen.
• Slot volatility: low volatility pays small wins often, high volatility pays rarely but larger. It affects how quickly a balance can fall.

Progressive jackpots pool a share of each stake into a prize that grows until won. They tend to have a lower base RTP, and bonus terms sometimes exclude them.

Mobile casino games run in a phone browser at most sites, and some have apps. We have no confirmed device information for the ten, so test the site on your own device.

Live dealer, blackjack, roulette and baccarat

Live dealer games are streamed from a studio with a human dealer. Blackjack, roulette and baccarat are the core options, and each has variants.

• Blackjack: the house edge depends on the rules, such as the payout on a blackjack and whether you can double after a split. It is also often a low-contribution game for bonuses.
• Roulette: European roulette has one zero and American has two, which raises the house edge.
• Baccarat: a simple game with banker and player bets, where the banker bet often carries a commission.

Game counts and provider logos do not prove quality. A large lobby can have many duplicates, and a logo does not show the games are genuine or offered at a fair RTP. Regional availability can also change: some providers withhold titles from certain countries.

Game providers at non GamStop casinos

Software providers build the games. Well-known names you may see include:

• Pragmatic Play: slots, live casino and crash-style games, with popular titles like Gates of Olympus and Sweet Bonanza.
• Novomatic: a long-established maker of land-based and online slots.
• Evolution Gaming: the best-known live dealer supplier, with blackjack, roulette, baccarat and game shows.
• Playtech: a large supplier of casino and live games.
• NetEnt: known for titles such as Starburst.
• Play'n GO: maker of Book of Dead and many mobile-friendly slots.
• Big Time Gaming: creator of the Megaways mechanic.
• Microgaming: one of the earliest suppliers, associated with progressive jackpots.

We do not have confirmed provider lists for the ten casinos in this comparison. Some providers restrict their games in certain territories, and unofficial copies of games exist on some sites. Check the game's information panel and the provider's own site.

Betting sites not on GamStop: sports betting alongside the casino

Some casinos share an account and wallet with a sportsbook, and some do not. We have no supplied evidence that any of the ten casinos offers sports betting, so verify this on each site. Where a shared wallet exists, a single balance funds both, but casino bonuses and sports free bets generally have separate terms.

Where betting sites not on GamStop do offer a sportsbook, check the markets available, including esports, and whether both pre-match and in-play betting are offered. Bet types include singles, accumulators (several selections combined, with odds multiplied) and bet builders (several outcomes from one match). Cash-out lets you settle a bet before it finishes, often at a reduced return.

Sports free bets differ from casino bonuses in these ways:

• Minimum qualifying odds: for example decimal odds of 1.50 or higher.
• Qualifying markets: some free bets exclude certain bets.
• Expiry: free bets often expire in days.
• Stake returned: a £10 free bet at decimal odds of 3.00 would usually return £20 in winnings, not £30, because the stake is not returned.

Self-exclusion at casinos not on GamStop

Non GamStop casinos are not a way to get around self-exclusion. If you have excluded yourself through GAMSTOP, using a site outside the scheme removes the safeguard you chose. GAMSTOP exclusion periods are six months, one year or five years, and cannot be shortened.

Many overseas casinos have their own tools: deposit limits, loss limits, time-outs and self-exclusion. These vary in length and enforcement, and they are not linked to other sites. Ask in writing whether an exclusion covers linked brands and any sportsbook, and whether marketing stops.

Gambling blocking software such as Gamban and BetBlocker can block gambling sites across your devices. GamCare offers free, confidential support on 0808 8020 133 and online chat, and the National Gambling Support Network is available 24 hours a day. Our Responsible Gambling page has further information. If gambling is causing harm, stop and seek support.

Choosing between these casinos not on GamStop

For a British reader, the useful questions are consistent: is the offer in pounds, can the licence be matched to the exact domain, are the wagering and cashout terms stated, and which withdrawal methods are documented. Ratings and offer sizes do not settle these questions. Most of the answers for the ten casinos remain unconfirmed in the supplied information, so read the operator's own terms and set your limits before you deposit.
