Sites Not on GamStop - Best Online Casinos Compared
Non GamStop casinos give UK players a wider range of games, bigger welcome packages and more payment flexibility than sites tied to the local exclusion scheme. We've researched licensing, bonuses and banking across the market so you can compare sites not on GamStop side by side before you decide where to play.
We check which authority licenses each operator, whether the site publishes RTP data, and whether basic account protection tools such as deposit limits are available.
We look at how many slot studios, live tables and jackpot titles a casino offers, not just the headline number, so the range actually matches what's advertised.
Headline percentages mean little without fair wagering requirements. We weigh the size of an offer against its terms, caps and time limits before ranking it.
What are non GamStop casinos?
GamStop is the UK's free self-exclusion scheme, letting players block themselves from casinos and betting sites licensed by the UK Gambling Commission (UKGC) for a set period. Non GamStop casinos sit outside that scheme entirely. They're licensed by other regulators, typically in Curaçao, and are not connected to GamStop's database, so a UK self-exclusion doesn't apply to them. That's why some players search specifically for casinos not on GamStop, or for sites not on GamStop that still accept UK-based customers.
This page compares the leading options on the criteria that matter most for this kind of search: how each site's bonus actually works, what games are on offer, how deposits and withdrawals are handled, and what legal and eligibility points UK readers should understand before signing up.
Our top picks: mini reviews and comparison

| Casino | Editorial Rating | Welcome Offer |
|---|---|---|
| Betmica | 10.0 | 570% up to £5,700 + 270 Free Spins |
| Kikibet | 9.9 | 350% up to £5,555 + 300 Free Spins |
| Betninja | 9.9 | £1,000 Bonus + 100 Free Spins |
| WinnerIsland | 9.7 | Up to €1,000 + 100 Free Spins |
| Zombillion | 9.7 | 250% up to £4,000 + 200 Free Spins |
1. Betmica
Betmica tops this list mainly on the strength of its welcome package: 570% up to £5,700 plus 270 free spins is one of the largest match offers we've come across on a site not on GamStop. What matters here is reading the wagering requirement and maximum bet rules that come attached to a bonus this size, since large percentage matches usually carry higher playthrough conditions than a modest £100 deal. A genuine limitation is that headline offers of this scale are typically split across multiple deposits, so new players shouldn't expect the full amount to land after a single top-up.
2. Kikibet
Kikibet's 350% up to £5,555 with 300 free spins is aimed squarely at slot players wanting volume of spins over a single big cash match. It's a strong second pick for anyone comparing slots not on GamStop rather than table games, given the free spin count. The drawback is that spin winnings on these packages are often capped or subject to their own separate wagering, so it's worth checking the terms before assuming the full spin value converts to withdrawable funds.
3. Betninja
Betninja takes a simpler approach: a flat £1,000 bonus plus 100 free spins for all new players, rather than a percentage match. That makes the offer easier to understand upfront, which suits players who find tiered percentage bonuses confusing. The limitation is that a flat bonus of this size usually requires a specific qualifying deposit to unlock in full, so smaller deposits may only receive a partial match.
4. WinnerIsland
WinnerIsland's welcome bonus is more modest, up to €1,000 with 100 free spins, but that smaller headline figure often comes with correspondingly lighter wagering terms, which can suit players who prioritise being able to actually withdraw a bonus over chasing the biggest number advertised. The trade-off is that players specifically hunting the largest possible match will find better value higher up this list.
How the money works: deposits, withdrawals and costs
Non GamStop casinos are not bound by the UKGC's card-payment restrictions, so the range of accepted payment methods is often wider than on UKGC-licensed sites. Typical options across this market include:
- Debit and credit cards – widely accepted, though processing times for withdrawals vary by operator
- E-wallets – generally the fastest route for both deposits and payouts
- Cryptocurrency – increasingly common, sometimes with lower minimum deposits and quicker processing
- Bank transfer – reliable but usually the slowest withdrawal method
Playing itself doesn't cost anything beyond the money a player chooses to deposit and stake in GBP. Where fees can apply is on withdrawal — some payment providers or currency conversions add a charge — and there are usually minimum and maximum withdrawal limits per transaction or per day. Always check an operator's terms for exact limits and processing windows before relying on a particular method.
What you can actually play and bet on
"Casino" covers more ground than slots alone. Across the sites on this page, the typical range includes:
- Slot machines – classic three-reel games through to modern Megaways and progressive jackpot titles
- Table games – roulette, blackjack and baccarat in multiple variants
- Live dealer games – real-time tables and game shows streamed from studios
- Specialty and instant games – crash games, scratch cards and similar fast-play titles on some sites
Beyond the casino floor, several operators covered here also run a sportsbook, meaning readers searching for betting sites not on GamStop can typically use the same account to bet on football, tennis, horse racing and other major sports, alongside casino play. This is worth checking site by site, since not every casino brand carries an equally strong sports offering.
Non GamStop casinos vs UKGC-licensed casinos
| Factor | Non GamStop Casinos | UKGC-Licensed Casinos |
|---|---|---|
| Regulator | International (e.g. Curaçao) | UK Gambling Commission |
| GamStop self-exclusion | Not connected | Enforced |
| Card payment rules | Generally more flexible | Credit card gambling restricted |
| Bonus sizes | Often larger percentage matches | Typically smaller, tightly regulated offers |
Neither category is inherently "better" across the board — the right choice depends on what a player is looking for, including bonus structure, game selection and payment preferences.
Legal standing and who these sites are for
It is not illegal for adults in Great Britain to play at casinos licensed outside the UK. These sites operate under the licensing regime of their home jurisdiction rather than the UKGC, which means UK consumer protections tied specifically to UKGC licensing — such as mandatory GamStop enforcement — do not apply in the same way. Players should be at least 18, should read an operator's own terms and licensing information before registering, and should understand that dispute resolution and consumer protection may work differently than with a UKGC-licensed brand. For guidance on managing gambling responsibly, including outside the GamStop scheme, see our Responsible Gambling page.
How to choose a casino from this list
A few practical checks before signing up:
- Read the wagering requirement and maximum bonus withdrawal on any welcome offer, not just the headline percentage
- Confirm your preferred payment method is supported for both deposits and withdrawals
- Check whether the game library includes the specific titles or providers you actually want to play
- Look for account-level controls such as deposit limits, even on sites outside the UKGC framework
How we rated and ranked these casinos
Our rankings are based on researching each operator's published licensing information, the structure and terms of its welcome bonus, the breadth of its game library, and the payment methods it advertises. Commission from any affiliate link does not influence a casino's position on this page — ratings reflect our independent research process, not payment received.

The positives of playing at non GamStop casinos
Players who look beyond the UKGC framework often do so for specific reasons: larger and more flexible welcome bonuses, a wider range of payment methods including cryptocurrency, access to game studios and titles not always available on UK-licensed sites, and fewer restrictions on deposit and betting limits. For players who understand the differences in regulatory protection and choose to gamble responsibly, non GamStop casinos can offer a broader and more flexible experience than the UKGC market alone provides.
