New Casinos Not on GamStop - Payout Options Compared
Non GamStop casinos are online gambling sites that operate under international licences and sit outside the UK's self-exclusion register. They attract UK players with larger welcome packages, a broader game catalogue and fewer deposit restrictions than many domestically licensed platforms. We've researched and ranked the best options available right now.
Every site we list holds a valid licence from a recognised international authority — most commonly Curaçao. We verify that licences are current and that the site uses SSL encryption and independently audited RNG software before recommending it.
We assess the headline welcome offer, the attached wagering requirements, the time limits and any game restrictions. A big percentage figure means little if the conditions make it unplayable — we factor that in when we score each casino.
We look at the deposit and withdrawal methods accepted, the minimum and maximum transaction limits, and how quickly cashouts are processed. Sites that slow-walk withdrawals or bury fees in small print rank lower, regardless of their other qualities.
What GamStop Is — and Why Some Players Look Elsewhere
GamStop is a free self-exclusion service run in partnership with UK Gambling Commission (UKGC) licence holders. When a player registers, they are locked out of all participating UKGC-licensed sites for a minimum of six months, up to five years. It was designed as a responsible gambling tool, and for many people it does exactly what it should.
Non GamStop casinos are platforms that hold licences from other jurisdictions — most commonly Curaçao — rather than the UKGC. Because they are not part of the UKGC framework, GamStop exclusions do not apply to them. They are legally permitted to accept UK players, and UK law does not prohibit adults from playing at internationally licensed sites.

How We Researched and Ranked These Casinos
Our editorial team reviewed each site on the list independently. No casino can buy its position — commercial relationships may result in a commission if you visit a site, but rankings are determined by our scoring criteria alone. The factors we weighted most heavily are set out in the rating cards above. Below are the additional checks we applied:
- Licence validity: confirmed active at the time of review
- Game library: breadth of software providers and title count
- Bonus fairness: wagering requirements, eligible games and time limits read in full
- Payment options: number of methods, GBP acceptance, withdrawal ceilings
- Customer support: availability of live chat, response times and language support
- Mobile experience: playability on iOS and Android without a native app
Top Non GamStop Casinos Reviewed
The offer cards above show the full ranked list. Here we go deeper on the casinos that stood out most clearly during our review process.
Betmica — Our Top-Ranked Pick
Betmica earns its place at the top of our list primarily because of the scale and structure of its welcome package. The 570% match up to £5,700 plus 270 free spins is one of the largest by headline value among the sites we reviewed — and unusually, the bonus is structured across multiple deposits rather than loaded onto one large, hard-to-clear requirement. That design gives players more time to evaluate the platform before committing significant funds.
The game library is anchored by a strong slots selection from multiple software suppliers, and the site processes GBP deposits, which removes the currency-conversion friction that affects some internationally licensed casinos. Live chat support is accessible around the clock.
Limitation: The size of the welcome offer means the overall wagering requirement attached to it is substantial. Players who prefer smaller, simpler bonuses may find it easier to clear a less dramatic package elsewhere.
Kikibet — Strong Runner-Up
Kikibet's 350% match up to £5,555 plus 300 free spins gives it one of the highest free-spin counts on this list, which makes it a particularly attractive option for slot players who like to extend their session on bonus credit. The site's game catalogue covers slots, table games and a live casino section, and it accepts GBP.
The platform is well-organised and straightforward to navigate, which matters for players arriving from a different casino environment. Promotional activity continues beyond the welcome stage with reload offers and free-spin drops.
Limitation: Kikibet is a newer brand, so its long-term track record for consistent payout processing is shorter than that of some more established names on this list. Check the current withdrawal terms before depositing a large sum.
Smash Casino — Best for High-Stakes Slots Players
Smash Casino's 600% up to €10,000 slots welcome package is built specifically around slot play, which is both its greatest strength and its most important caveat. If slots are your primary game, the multiplier and ceiling are exceptional. If you prefer table games or live casino, the bonus may not apply to those areas, so read the terms before you claim.
The site holds a Curaçao licence and accepts a range of payment methods including e-wallets and cryptocurrency alongside more traditional options. The slots library is extensive, drawing on titles from several well-regarded studios.
Limitation: The €10,000 ceiling is quoted in euros rather than GBP, so the effective maximum in pounds will vary with the exchange rate at the time of your deposit. Currency conversion fees may also apply depending on your payment method.
Rivo — Best Cashback Offer
Rivo distinguishes itself with a hybrid welcome structure: a 1,000% slots bonus up to €10,000 combined with 25% cashback. The cashback element is genuinely useful — it returns a portion of net losses during the promotional window, which softens the variance risk that comes with working through a large first-deposit bonus.
The site's game library leans heavily into slots but includes a live casino section. Support is available via live chat and email.
Limitation: Like Smash Casino, Rivo quotes its maximum in euros. The cashback percentage is appealing, but confirm the calculation method and eligible games before relying on it as a safety net.
Betninja — Straightforward Value
Betninja takes a cleaner approach than some of its peers: a £1,000 bonus plus 100 free spins for all new players, quoted directly in GBP. For players who find the multi-stage or percentage-heavy packages at other sites confusing, the clarity here is a genuine selling point. The site also extends beyond the casino into sports betting — see the sports section below.
Limitation: The headline bonus ceiling is lower than several competitors on this page, so players with a large initial deposit budget may find the match percentage less competitive once they reach the cap.

How Bonuses and Payments Work at Non GamStop Casinos
Most welcome packages at these sites are percentage deposit matches — the casino adds a proportion of your first deposit (or first few deposits) as bonus credit. Free spins are typically awarded either immediately on sign-up or after your first qualifying deposit, and they apply to specified slot titles rather than the full library.
Before you claim any offer, check these four things:
- Wagering requirement: how many times you must play through the bonus before it converts to withdrawable cash. A 570% bonus with a 40× requirement needs significantly more play than a 100% bonus with a 20× requirement.
- Eligible games: table games and live casino titles often contribute a fraction (or nothing) toward clearing a wagering requirement. If you play those games, the effective value of a slots-only bonus drops sharply.
- Time limit: bonuses expire. Most sites give between seven and thirty days to clear the wagering requirement. Unused bonus and any winnings from it are typically forfeited after that window closes.
- Maximum cashout: some offers cap the amount you can withdraw from bonus winnings, regardless of how much you win. This is separate from your real-money balance.
Deposits and Withdrawals
Non GamStop casinos generally accept a wider range of payment methods than UKGC-licensed operators, including options no longer available at UK-regulated sites. Common methods across our listed casinos include:
- Debit cards (Visa, Mastercard) — widely accepted for deposits; withdrawal availability varies by site
- E-wallets (Skrill, Neteller, ecoPayz) — typically the fastest withdrawal route, often same-day or within 24 hours
- Prepaid cards (Paysafecard) — useful for deposit-only play; not universally supported for cashouts
- Cryptocurrency (Bitcoin and others at select sites) — fast, borderless and increasingly common at internationally licensed casinos
- Bank transfer — available at most sites but typically carries the longest processing time, from two to five business days
Minimum deposit thresholds are usually between £10 and £20. Withdrawal minimums vary more widely — check before you play if you plan on cashing out smaller amounts. Sites that quote bonuses in euros will convert your GBP deposit at the prevailing exchange rate; factor that into your real-money budgeting.
What You Can Play at Non GamStop Casinos
The game libraries at these sites are sourced from independent software studios and tend to be broad. Here is how the catalogue typically breaks down:
- Slots: the largest section at every site on this list — classic three-reel games, video slots with bonus features, Megaways mechanics and branded titles. Some casinos stock thousands of individual slot titles.
- Table games: multiple variants of roulette (European, American, French), blackjack (classic, multi-hand, perfect pairs), baccarat and poker. Game counts vary; larger libraries offer both low-limit and high-roller tables.
- Live casino: real dealers streamed in real time, covering roulette, blackjack, baccarat and game-show formats such as Crazy Time, Monopoly Live and Lightning Roulette. Evolution Gaming is the dominant studio supplier across most of these sites.
- Jackpot games: progressive jackpot slots where the prize pool builds across multiple players. Several titles have paid seven-figure sums historically, though outcomes are always random and past pay-outs are not indicative of future ones.
- Speciality games: scratch cards, virtual sports, keno and bingo appear at a number of sites on this list, providing a break from the main categories.
Sports Betting and Other Products at These Sites
Several casinos on this list operate a sports betting section alongside their casino product. Betninja is the clearest example — its name reflects a genuine dual focus, and UK players can wager on football, tennis, basketball, horse racing and other markets from the same account they use for casino play. WinnerIsland and Zombillion also offer sports betting functionality.
What this means practically: you can switch between casino games and pre-match or in-play sports bets without opening a separate account or moving funds. Bonuses, however, are almost always product-specific — a casino welcome offer will not apply to sports wagers, and vice versa. Read each site's promotional terms to understand which wallet your bonus credit sits in.
Some sites also run poker rooms or virtual sports sections. These operate under the same licence as the main casino and share the same deposit wallet, but bonus terms and game contributions differ from the main casino.

Legal Position and Who Can Play
UK law does not make it illegal for an adult to play at an internationally licensed online casino. These sites hold licences from jurisdictions such as Curaçao, which authorise them to accept players from many countries including the United Kingdom. They are not, however, regulated by the UKGC, which means the consumer protections built into the UK licensing regime — such as mandatory participation in the GamStop scheme, the UKGC's dispute resolution process and the ban on credit-card gambling — do not apply.
In practical terms, this means:
- You must be 18 or over to play. All sites on this list state this requirement, and most will ask for age verification at the withdrawal stage if not before.
- Dispute resolution follows the process of the licensing jurisdiction, not the UK's. If you have a complaint, you would typically approach the casino's licence holder rather than the UKGC.
- GamStop exclusions do not carry across to these sites. If you are currently self-excluded via GamStop and choose to play at a non-GamStop casino, that is your own decision as an adult — but the exclusion exists for a reason. Tools to help you manage play at any site, including deposit limits and time-out features, are covered on our responsible gambling page.
- Winnings from online gambling are not subject to UK income tax for players — HMRC taxes operators, not individual gamblers.
Non GamStop Casinos vs UKGC-Licensed Casinos
| Feature | Non GamStop Casinos | UKGC-Licensed Casinos |
|---|---|---|
| GamStop exclusions apply | No | Yes — mandatory |
| Credit cards accepted | Varies by site | No — banned by UKGC |
| Welcome bonus size | Typically larger | Often lower caps |
| Regulator | Curaçao or equivalent | UK Gambling Commission |
| UK consumer dispute process | Not available | Available via UKGC |
| Deposit limits | Site-level controls | Mandatory affordability checks |
Neither type of site is universally better. The right choice depends on what matters most to you: the stronger consumer protection framework of a UKGC-licensed operator, or the broader game selection and larger bonuses typically available at internationally licensed alternatives.
How to Self-Exclude from a Non GamStop Casino
Because GamStop does not cover these sites, you cannot exclude from them via that service. However, every reputable internationally licensed casino offers its own self-exclusion mechanism. The process usually works like this:
- Log into your account and go to the responsible gambling or account settings section.
- Choose a self-exclusion period — options typically range from one month to permanent closure.
- Confirm your choice. Most sites require you to re-authenticate (via email or SMS) before the exclusion takes effect.
- Once active, your account will be suspended for the chosen period. You should not be able to log in or receive marketing from the site.
If you are having difficulty locating these controls, contact customer support directly and request a self-exclusion. Reputable sites are required by their licence conditions to honour this request. For more tools and support resources, visit our responsible gambling page.
Choosing the Right Site for You
With ten reviewed casinos on this list, the practical question is which one fits your playing style. A few simple decisions narrow it down quickly:
- Prefer GBP bonuses with no currency conversion? Betmica, Kikibet, Betninja, Zombillion and Daytonaspin all quote their welcome offers in pounds.
- Primarily a slots player? Smash Casino and Rivo both build their welcome packages specifically around slot play, with the highest multipliers on the list.
- Want sports betting alongside casino? Betninja, WinnerIsland and Zombillion all carry sports markets.
- After the largest raw bonus ceiling? Rivo and Smash Casino both offer up to €10,000, though the conditions attached to packages that size are significant — read them before committing.
- Prefer a simpler, clearly structured offer? Betninja's £1,000 bonus and 100 free spins is the most straightforwardly described package on the list.
