Welcome to payoutlab.co.uk — the UK's most-tested non-GamStop casino list 🎰
Every game. Every studio. Where to play without UK limits.
This site is about the games, not just the casinos. Every page below covers one game, game type or studio — what it is, how its maths works, how the UK version differs, and which sites not on GamStop carry it.
The reason that matters: since 2021 the UK Gambling Commission has capped online slots at £2 a spin, banned bonus buys, removed autoplay and turbo, and forced a minimum spin cycle. Offshore operators have none of those restrictions, so the same game genuinely plays differently.
Below are the sites we tested. Each one has been deposited into and withdrawn from, with the payout time recorded.

Every site on this page will quote you an RTP and a bonus. These calculators turn those numbers into pounds, and show the spread around them rather than the single average that almost never happens. They run in your browser — nothing is sent anywhere.

Most non-GamStop lists rank by commission. We rank by measured payout speed. Below are the four most recent tests, with the month each was run.
Ranking criteria, in order: measured withdrawal time · licence verified on the regulator's register · whether bonus terms are honoured in practice · game range and provider quality · complaint volume on Trustpilot and Reddit · which payment rails actually work for UK cards.
GamStop is the UK's national online self-exclusion scheme. Every operator holding a UK Gambling Commission licence is legally required to connect to it, which is why registering once blocks you across every British site at the same time.
"Non-GamStop games" is shorthand for the games you can play at operators that hold no UKGC licence — sites regulated in Anjouan, Curaçao or Costa Rica instead. They are not connected to the GamStop database, and because they sit outside UKGC scope they are not bound by the rules the Commission introduced for the British market.
That last part is the whole story. The games are the same games, from the same studios, running the same engines. What changes is the configuration: the stake ceiling, whether the bonus buy is switched on, how fast a reel can spin, and which RTP build the operator chose to run. This page covers each of those, game type by game type.
Offshore lobbies carry the same categories a UK site does, but several of them behave differently once the UKGC rulebook stops applying. These are the ones worth knowing about, each with its own page on this site.
The category where the difference is largest. UK slots are capped at £2 a spin; offshore the same titles routinely accept £100 or more. Bonus buy features — paying directly to trigger a feature round — are banned in Britain and available almost everywhere else. Average RTP across the sites we list sits between 95.9% and 96.4%. Slots not on GamStop →
Volatility matters more than RTP for how a session feels. A 96% low-volatility slot pays small and often; a 96% high-volatility slot pays rarely and large. Same expected return, completely different experience — and offshore, with no stake cap, the high-volatility end is where bankrolls disappear fastest.
Big Time Gaming's licensed reel engine, where the symbol count on each reel changes every spin to produce up to 117,649 ways to win. Because the format is built around high variance, the £2 cap does not reduce the risk — it just stretches the time you are exposed to it. Offshore builds keep the bonus buy. Megaways slots not on GamStop →
There are now well over a hundred licensed Megaways titles, and quality varies enormously. The originals — Bonanza, Buffalo Rising, Extra Chilli — remain the reference points; many later clones simply bolt the engine onto weaker maths.
The dealers, studios and camera feeds are identical to the ones UK sites use, because most run the same Evolution licence. The ceilings are not identical. Offshore live tables commonly accept stakes several multiples above their UK equivalents on precisely the same table. Live casino not on GamStop →
Check the studio before the table. A lobby running Evolution, Pragmatic Live and Playtech is a serious one; a lobby running studios you have never heard of is usually white-labelled and thinly staffed at quiet hours.
Where the table-limit gap is most visible. Look for Lightning Roulette for its 500× multipliers, Immersive for the production values, Auto for the fastest cycle, and French Roulette for the lowest house edge on the floor at 1.35%. Roulette not on GamStop →
European and French wheels have a single zero and a 2.7% house edge. American wheels add a double zero and push it to 5.26% — nearly twice the cost for an identical-looking game. Always check which wheel you have opened.
The lowest house edge in any casino when played with correct basic strategy — around 0.5% on favourable rules. Which rules the operator runs matters far more than which casino you pick: blackjack paying 3:2 rather than 6:5 is the single biggest factor. Blackjack not on GamStop →
The rule to look for is the payout on a natural. Blackjack paying 3:2 is standard; 6:5 roughly triples the house edge on the same table with the same dealer. It is the most expensive detail in any casino and the easiest to miss.
A British format that never travelled: a five-reel slot strip crossed with a 5×5 bingo grid. Published RTPs range wider than slots do, roughly 92% to 96%, and the effective figure depends heavily on whether you buy extra spins. Slingo not on GamStop →
Instant-win games with fixed, published prize tables — among the most transparent products in any lobby. RTPs sit lower than slots, typically 90% to 96%, and they are frequently excluded from bonus wagering. Scratch cards not on GamStop →
Dice, crash, plinko, mines and limbo — games the operator builds itself rather than licensing in. The ones worth playing are provably fair: the outcome is generated from a server seed and a client seed you control, so you can verify afterwards that the result was fixed before you played. Conventional casino games offer nothing comparable.
These are the specific slots British players look for by name when they go looking outside the UK market. Each has its own page here covering the maths, the RTP builds the studio ships, and which sites carry it.
The pattern across all of them is the same: identical artwork, identical mechanics, different configuration. The stake ceiling changes, the bonus buy reappears, and the RTP build becomes the operator's choice rather than a displayed obligation.
| Game | Studio | RTP (advertised) | Volatility | Max win |
|---|---|---|---|---|
| Book of Dead | Play'n GO | 96.21% | High | 5,000× |
| Fishin' Frenzy | Blueprint Gaming | 96.12% | Medium-high | 5,000× |
| Big Bass Bonanza | Pragmatic Play | 96.71% | High | 2,100× |
| Eye of Horus | Merkur / Blueprint | 96.31% | High | 5,000× |
| Fluffy Favourites | Eyecon | 95.39% | Medium | 5,000× |
| Starburst | NetEnt | 96.09% | Low | 500× |
| Big Bass Splash | Pragmatic Play | 96.71% | High | 5,000× |
| Rainbow Riches | Barcrest | 95.00% | Medium | 500× |
One habit covers all of them. Whichever title you open, check the paytable first. The RTP shown there comes from the build that operator is running, and it is the one number a casino cannot quietly edit. How to read it →
Which studios a lobby carries tells you more than the total game count does. These are the ones that dominate UK search demand, and the ones whose absence should make you look twice.
The highest-volume slot studio in the market and the one whose bonus buy is most missed on UK sites. Big Bass Bonanza, Gates of Olympus and Sweet Bonanza are its best-known families. Pragmatic ships most titles in several RTP builds — commonly 96.5%, 95.5% and 94.5% — so the paytable is worth opening. Pragmatic Play →
The Swedish studio behind Starburst, the default free-spins game across the entire industry, and Gonzo's Quest, which invented cascading reels. Now part of Evolution, so operators carrying Evolution live tables usually carry NetEnt slots too. NetEnt →
Based in Newark and unusually UK-centric, which is why it dominates British search. Fishin' Frenzy and Eye of Horus are the two titles you will see everywhere. It also holds a Megaways licence, so several of its games exist in both classic and Megaways builds. Blueprint Gaming →
The dominant live-dealer supplier worldwide and the main reason to choose one live lobby over another. Because the licence is expensive, plenty of offshore casinos advertise "live casino" while running only smaller studios. The named titles — Crazy Time, Lightning Roulette, Monopoly Big Baller — are how you tell. Evolution Gaming →
Play'n GO built Book of Dead, the Egyptian expanding-symbol slot that defined a decade of UK play. Nolimit City and Hacksaw specialise in extreme volatility — Folsom Prison, Fire in the Hole, San Quentin — with ceilings running into five figures times stake. All three are staples of offshore lobbies and increasingly rare on UK ones.
Between 2020 and 2021 the Gambling Commission introduced a package of changes to online slots. None of them altered the RTP directly; all of them altered how a session feels. This is the concrete list of what a UK-licensed site can no longer offer you.
Online slots are capped at £2 a spin for all players, and £5 for those aged 18 to 24 under later affordability rules. Offshore operators apply no equivalent ceiling, and £100+ per spin is common on mainstream titles.
Paying a fixed multiple of your stake — usually 75× to 100× — to trigger a feature round directly. Banned outright in Britain since 2021. Where a studio ships the feature, offshore builds keep it.
Removed entirely from UK sites. Every spin must be individually initiated. Offshore, autoplay and turbo both remain standard.
UK slots must take at least 2.5 seconds per spin, and features that create an illusion of control — slam stops, quick spin — are prohibited. Offshore titles run at the studio's original pace.
UK operators may no longer let you cancel a pending withdrawal and put the money back into play. Many offshore sites still permit it, which is convenient and, honestly, the feature most likely to cost you money.
This is the part of offshore play that gets the least attention and deserves the most. Return to Player is the percentage of all wagered money a game returns across millions of spins — 96% RTP means £96 back for every £100 staked over the game's full cycle, not over your session.
What most players do not realise is that the same slot ships in several RTP configurations, and the operator picks which one to run. Pragmatic Play, Play'n GO, NetEnt and Red Tiger all publish multiple builds of their headline titles — commonly 96.5%, 95.5% and 94.5%, occasionally as low as 88%.
UK-licensed sites must display the RTP of every game. Offshore sites are under no such obligation. That does not mean they run lower builds — several of the operators on this page run the studio default — but it does mean the burden of checking sits with you.
Checking takes ten seconds. Open the game, click the information or paytable icon, and scroll to the final screen. The figure shown there comes from the build you are actually playing, which is the one number an operator cannot quietly edit. Our full RTP guide walks through it →
A worked example. A 94% build costs three times as much per £100 staked as a 98% build. Over 2,000 spins at £2 that is the difference between an expected cost of £120 and £40 — on the same game, with the same artwork, at the same casino.
These four terms are used interchangeably across this niche and they do not mean the same thing. Two of them describe something that never blocked you in the first place.
| Term | What it actually means | Does it block you? |
|---|---|---|
| Non-GamStop | Not connected to the UK's national self-exclusion database | No |
| Non-UK | Holds no UKGC licence at all — the broadest of the four | No |
| Non-GamCare | Not affiliated with the GamCare charity. GamCare provides support and never blocked any account | No — it never did |
| Non-GamBlock | Not covered by GamBlock, blocking software you install on your own device | Only if you installed it |
The regulator is the single most useful thing to check, and the thing most lists skip. A badge in a footer proves nothing — verify the number on the regulator's own register.
| Regulator | Standing | Player recourse | Used by |
|---|---|---|---|
| Anjouan (ALSI) | Newer, growing quickly | Limited — complaints go to the operator | FortuneJack, Gamdom |
| Curaçao (CGA) | The most common offshore licence; a new framework arrived in 2024 adding ADR | Moderate | BitStarz, Stake, Cloudbet and most others here |
| Costa Rica | A company registration rather than true gaming licensing | Effectively none | Avoid unless the brand is long-established |
Payout speed is the clearest quality signal in this category, and the rail you choose matters more than the casino you choose. Every figure below comes from our own timed withdrawals.
| Method | Deposit | Withdrawal (measured) | Notes |
|---|---|---|---|
| Litecoin / USDT | Instant | 15–30 min | Fastest route by a wide margin; lowest network fees |
| Bitcoin | 10–30 min | 30–50 min | Slower and dearer when the network is congested |
| Visa / Mastercard | Instant | 1–3 working days | Leaves the casino fast; your bank is the delay. Some UK banks decline gambling MCC codes |
| Paysafecard | Instant | Deposit only | You cannot withdraw to it |
| Skrill / Neteller | Instant | Usually same day | Frequently excluded from bonus eligibility |
PayPal is not an option. No genuine casino outside the UK market offers it — PayPal only partners with licensed operators in regulated markets. Any site advertising PayPal in this category is worth treating with real suspicion.
Offshore welcome offers look far larger than UK ones because nothing caps the advertised value. A "500% bonus" is a match across several deposits, not cash in your account. Three terms decide whether you ever see any of it.
35× to 45× on the bonus amount is standard; below 30× is genuinely good. Check whether it applies to the bonus alone or to deposit plus bonus — the second doubles the work for the same headline number.
Usually £5. Breaching it voids the bonus, and this is the single most common reason a withdrawal is refused at any offshore casino. It is also the easiest term to breach by accident on a site with no stake cap.
On no-deposit and free-spin offers, winnings are frequently capped at 5× to 10× the bonus regardless of what you actually win.
Slots normally clear wagering at 100%, table games at 10%, live dealer often at 0%. Playing blackjack to clear a slots bonus can mean making no progress at all. Full guide to wagering →
Honestly: less safe than a UKGC site, and it would be dishonest to pretend otherwise. Here is the trade in both directions, without the marketing.
No £2 stake cap. Bonus buy features. Autoplay and turbo. Higher live table ceilings. Crypto payouts measured in minutes rather than banking days. Verification that is risk-based rather than mandatory before your first withdrawal.
UKGC oversight. Access to the UK complaints route and independent dispute resolution. Deposit-limit prompts and affordability interventions. The requirement that player funds are held to UK standards. If an offshore operator refuses to pay, your options are the regulator's own process — which is slower and weaker than the UK equivalent — and public pressure.
Pick operators trading for more than two years — the ones that stop paying rarely last that long. Verify the licence number on the regulator's register rather than trusting a footer badge. Complete KYC at registration, not at withdrawal. Keep balances small and withdraw regularly instead of letting funds build up. And read the bonus terms before you accept, not after a payout is refused.
It is worth understanding the commercial logic, because it explains what kind of business you are dealing with.
A UKGC licence is expensive and demanding. It brings affordability checks, mandatory GamStop integration, the £2 slot cap, a ban on bonus buys, strict advertising rules and a levy on gross gambling yield. For an operator whose product is built around high stakes, crypto rails and feature-rich slots, complying means removing most of what makes the product distinctive.
So they do not apply. Instead they license in Anjouan or Curaçao, where the requirements are lighter and the fees a fraction of the UK equivalent, and they accept UK traffic without soliciting it directly. That is the grey area this entire category lives in: not illegal for you to use, not licensed to advertise to you.
The practical consequence is that these operators compete on the things the UK market removed — stake freedom, bonus buys, payout speed and payment choice — because those are the only axes left where they can beat a British site.
Set side by side, the differences are specific rather than vague. This is the whole trade in one table.
| UKGC-licensed site | Site not on GamStop | |
|---|---|---|
| Slot stake cap | £2 per spin | None — £100+ common |
| Bonus buy | Banned since 2021 | Available where the studio ships it |
| Autoplay / turbo | Removed | Standard |
| Minimum spin time | 2.5 seconds | Studio default |
| RTP displayed | Mandatory | Not required — check the paytable |
| Verification | Before first withdrawal | Risk-based; often not on crypto |
| Crypto accepted | No | Yes, and usually the fastest route |
| Withdrawal speed | 1–5 working days | 15–50 minutes on crypto |
| GamStop self-exclusion | Enforced | Not connected |
| Complaints route | UKGC and independent ADR | The offshore regulator only |
| Deposit limits and prompts | Mandatory | Voluntary tools, if offered |
Offshore promotion is more varied than the standard British welcome match. These are the formats worth recognising, roughly in order of how much they are usually worth.
A share of the house edge returned on every wager, paid as cash with no playthrough attached. It looks unimpressive next to a 500% headline and is almost always worth more to a regular player, because there is nothing to clear and nothing to forfeit. Stake, Roobet and Gamdom all build their offer around it.
A percentage of net losses returned, usually weekly, with no wagering condition. Betpanda and Cryptorino both run 10%. The wager-free part is what gives it value — cashback carrying 40× playthrough is a bonus wearing a disguise.
The familiar format: a percentage of your deposit, often spread across the first two to four deposits. Offshore headlines run from 100% to 500%. The percentage is a ceiling, the multiplier is the price, and the max-bet rule is where most people lose the bonus.
Usually bundled with a welcome match and tied to one specific slot — very often Starburst, because its low volatility makes the operator's exposure predictable. Check the spin value and whether winnings are capped.
Small, heavily restricted, and capped on cashout at typically 5× to 10× the bonus. Useful for seeing whether you like a lobby; not a route to profit.
Recurring matches on later deposits, usually smaller than the welcome offer. Worth more than a welcome bonus over a season if you deposit regularly.
Larger matches with correspondingly larger minimum deposits. The multiplier is usually the same, so the absolute cost of clearing rises with the amount.
An extra percentage for funding in coin rather than card. It reflects the operator's own saving on processing fees, which is why it exists at all.
The mechanics are simpler offshore than in the UK, but two steps in this sequence are the ones that determine whether your first payout takes minutes or days.
Start from the game rather than the bonus. It is the faster route to a site you will actually keep using.
Most non-GamStop lists are ordered by commission. Ours is ordered by measured payout speed first, then by the checks below. Where two operators are close, the one with the longer trading history wins.
Every site here has been opened with a real account, funded with our own money and cashed out at least once. A site we cannot withdraw from does not appear, regardless of what it pays.
If you want the widest game range with both crypto and card payments, FortuneJack is the site on this page we would pick — 7,000+ slot games, no stake cap, and the fastest payout we measured at under 15 minutes.
If anonymity matters more than breadth, Betpanda asks for less identification than anything else here. If you bet as well as spin, Cryptorino's sportsbook is the strongest. If verifiable licensing is what reassures you, BitStarz is the only operator here publishing a licence number you can check.
Whichever you choose, the habits matter more than the pick. Verify the licence, complete KYC before you need it, read the max-bet rule before accepting a bonus, open the paytable to see which RTP build you are playing, and withdraw regularly rather than letting a balance sit offshore.
This page is re-tested monthly and the payout times are re-measured each cycle.
