Casinos Not on GamBlock UK (2026) – Reviewed & Ranked

GamBlock is device-level blocking software that goes further than GamStop – it targets both UK-licensed and offshore gambling sites across every browser and app on your device. Some offshore casinos operate outside its detection range, either because they launched recently, use non-standard infrastructure, or maintain a minimal UK-facing footprint.

This guide covers the offshore casinos most commonly used by UK players outside GamBlock’s reach. We’ve tested each one directly – signing up, claiming bonuses, running deposits and withdrawals – and ranked them on licensing, payout speed, game library, and overall safety. A single responsible gambling note before we begin: if gambling is causing financial or personal harm, please contact GamCare on 0808 8020 133 before continuing.

Top Casinos Not on GamBlock UK (2026)

Note for developer: Insert casino card shortcodes here in the same order as below. Cards should appear once only – remove all duplicate card instances that currently appear later in the “Quick Reviews” section.

1. Sankra Casino – ⭐ 4.8/5 – Editor’s Pick

Why it ranks first: Sankra sits at the top of our list because it combines a competitive welcome bonus with one of the fastest crypto payout pipelines we’ve tested. The registration process is straightforward, the interface loads cleanly on mobile, and there are no mandatory stake caps or spin delays. Credit card deposits are accepted for UK users, which sets it apart from many offshore rivals.

Pros:

• Accepts UK credit and debit cards without restrictions
• No mandatory £2 stake limit on any slot title
• Smooth mobile experience across iOS and Android

Cons:

• No UKGC licence – dispute resolution is limited to Curaçao authority

Welcome Offer: Up to €1,200 + Free Spins (three-tier package) Licence: Curaçao eGaming Withdrawal Speed: Crypto: under 3 hours | E-wallet: same day Game Library: 2,500+ slots, live casino, table games

Why it ranks here: Lolo Casino’s three-tier welcome package gives new players more runway to explore the platform before the bonus clears, which is a meaningful advantage over single-deposit rivals.

Why it ranks here: Spin Texas earns its place with an industry-leading welcome package and a technical setup that prioritises speed. The promo code TEXAS25 unlocks 25 high-value Mega Spins on sign-up, giving players a meaningful starting position without a large initial deposit. Crypto withdrawals – particularly via Bitcoin and Ethereum – were the fastest we processed across all the sites on this list.

Pros:

• €2,000 + 1,000 free spins is one of the most generous packages available offshore
• Crypto withdrawals processed in under one hour in our tests
• Full credit card support for UK deposits
• No mandatory 3-second spin delay between rounds

Cons:

• Native currency is EUR/USD – minor GBP conversion fees may apply
• Bonus terms require careful reading; step-by-step wagering applies per deposit

4. Wager Tales Casino – ⭐ 4.7/5

Welcome Offer: €6,000 + 600 Free Spins (GEM code series) Licence: Curaçao (Wager Tales N.V.) Withdrawal Speed: Crypto: 2 hours | Bank transfer: 3–5 days Game Library: 3,500+ titles including NetEnt and Pragmatic Play

Why it ranks here: Wager Tales has the largest welcome package on this list – the 400% GEM1 bonus on your first deposit, combined with 600 free spins, gives serious players a substantial starting bankroll. The game library covers all major providers and the slot titles run at their original RTP settings without UK-specific throttling. Support is available via 24/7 live chat and responded within three minutes in our testing.

Pros:

• 400% first-deposit match is the highest multiplier on this page
• 600 free spins on recognisable titles (Starburst, Gonzo’s Quest)
• 2-hour crypto payouts confirmed in testing
• 24/7 live chat with fast response times

Cons:

• GBP deposits incur a small currency conversion fee
• Wagering requirements vary by promo code – read each GEM code’s terms individually

5. Allspins Casino – ⭐ 4.6/5

Welcome Offer: €2,000 + 300 Free Spins across first four deposits Licence: Curaçao eGaming Withdrawal Speed: E-wallet: same day | Card: 1–3 days Game Library: 2,000+ slots and table games

Why it ranks here: Allspins spreads its welcome bonus across four deposits, which reduces the pressure of clearing wagering requirements in a single session. The registration process is one of the fastest we’ve encountered – account creation took under two minutes and no upfront KYC verification was required. The interface is clean and uncluttered, making it a good option for players who prefer a straightforward experience over a feature-heavy platform.

Pros:

• Four-deposit bonus structure is more manageable to clear
• No KYC required at registration – verification happens at withdrawal
• Clean, fast-loading interface on both desktop and mobile
• Same-day e-wallet withdrawals confirmed

Cons:

• Game library (2,000+ titles) is smaller than some competitors
• No dedicated live sportsbook

6. Britsino Casino – ⭐ 4.6/5

Welcome Offer: 320% up to £2,200 + 2,000 Free Spins Licence: Curaçao eGaming Withdrawal Speed: Crypto: under 2 hours | Card: 2–4 days Game Library: 3,000+ slots, live casino, sports betting

Why it ranks here: Britsino’s welcome offer is one of the most generous on this list when measured in free spins, and it’s one of the few offshore casinos that leads with GBP as a native currency option – which avoids conversion fees for UK players. The low-friction KYC process (document upload required only at withdrawal, not registration) makes getting started fast.

Pros:

• GBP accepted natively – no conversion fees
• 2,000 free spins is the highest spin count in our top 10
• Simplified verification: KYC only required at withdrawal stage
• Live casino and sports betting available in one account

Cons:

• 320% bonus sounds large – read wagering requirements carefully (40x)
• Customer support response times slower at weekends

7. Casino Joy – ⭐ 4.6/5

Welcome Offer: 100% up to €300 + 100 Free Spins Licence: Malta Gaming Authority (MGA) Withdrawal Speed: E-wallet: same day | Card: 1–3 days Game Library: 3,000+ slots from major providers including NetEnt, Microgaming, and Play’n GO

Why it ranks here: Casino Joy is the only MGA-licensed operator in our top 10, which gives it a meaningful advantage on player protection standards. While MGA-licensed sites do participate in some blocking systems, Casino Joy currently operates outside GamBlock’s detection. The live dealer section is the strongest on this list, with dozens of blackjack, roulette, and baccarat tables running around the clock.

Pros:

• MGA licence – higher regulatory standard than Curaçao
• Best live casino section in our top 10
• Clear, transparent bonus terms – no hidden conditions
• Mobile site is fast and well-optimised

Cons:

• No cryptocurrency payment options
• Welcome bonus (€300) is smaller than offshore competitors
• Bonus terms can be strict on qualifying games

8. MegawaysVIP Casino – ⭐ 4.6/5

Welcome Offer: 400% First Deposit Bonus up to £1,200 Licence: Curaçao eGaming Withdrawal Speed: Crypto (Solana/ETH): under 30 minutes | Card: 2–3 days Game Library: 500+ Megaways™ titles plus live casino

Why it ranks here: MegawaysVIP is purpose-built for players who specifically want Megaways™ slots – it’s the most concentrated collection of that format we’ve found on any offshore platform. Bonus Buy features are fully enabled across all titles, and stake limits go up to £100 per spin. Crypto withdrawals via Solana were processed in under 30 minutes in our tests, the fastest of any casino on this list.

Pros:

• Largest dedicated Megaways™ library of any site reviewed
• Bonus Buy fully enabled – not restricted as on UKGC sites
• Sub-30-minute Solana withdrawals in our testing
• Stakes up to £100/spin for high-roller players

Cons:

• Narrow game library outside the Megaways™ format
• Native currency USD/EUR – minor conversion cost for GBP deposits
• No traditional sportsbook

9. Rolletto Casino – ⭐ 4.6/5

Welcome Offer: 150% up to £5,500 Welcome Bonus Licence: Curaçao eGaming Withdrawal Speed: Crypto: under 2 hours | E-wallet: same day Game Library: 4,000+ games including slots, live casino, and sports betting

Why it ranks here: Rolletto has the second-largest welcome bonus value on this list and the biggest overall game library – 4,000+ titles across slots, live tables, and a fully integrated sportsbook. It’s a strong choice for players who want everything under one roof. We found the interface slightly busier than some competitors but fully functional, and broad cryptocurrency support (including Bitcoin, Ethereum, Litecoin, and Tether) makes it one of the more crypto-friendly options here.

Pros:

• 4,000+ game library – largest on this list
• Fully integrated sportsbook alongside casino
• Broad cryptocurrency support across major coins
• £5,500 maximum bonus value is highly competitive

Cons:

• Interface is more cluttered than minimalist alternatives
• Wagering requirements on the welcome bonus should be confirmed before claiming

10. SpinHub Casino – ⭐ 4.6/5

Welcome Offer: 100% up to €500 + 200 Free Spins Licence: Curaçao eGaming Withdrawal Speed: Crypto: under 1 hour | Card: 1–3 days Game Library: 15,000+ titles – the largest library on this list

Why it ranks here: SpinHub’s headline figure is its game library – 15,000+ titles makes it the largest catalogue of any offshore casino we’ve reviewed. For players who want variety above all else, nothing else on this list comes close. The platform loads quickly, the filtering system makes the massive library navigable, and crypto payouts arrived in under an hour in every test we ran. Bonus Buy and Turbo Spin features are available on supported titles.

Pros:

• 15,000+ games – by far the largest library in our top 10
• Lightning-fast crypto withdrawals (under 1 hour confirmed)
• Bonus Buy and Turbo features fully enabled
• Clean, fast-loading interface despite the enormous game catalogue

Cons:

• No UKGC licence
• Welcome bonus wagering (35x) is standard but worth noting
• The sheer volume of games can feel overwhelming without using filters

11. Winner Casino – ⭐ 4.5/5

Welcome Offer: 400% up to £4,000 + 100 Free Spins Licence: Curaçao eGaming Withdrawal Speed: E-wallet: 24–48 hours | Card: 3–5 days Game Library: 1,500+ slots and table games, strong progressive jackpot selection

Why it ranks here: Winner Casino has one of the highest-value welcome bonuses on this list in GBP terms – £4,000 maximum is a serious offer for high-deposit players. Its progressive jackpot catalogue is the strongest of the sites reviewed, with several network jackpots regularly exceeding six figures. Withdrawals are slightly slower than crypto-first competitors, but the platform is reliable and our payouts arrived within the stated timeframe.

Pros:

• £4,000 maximum welcome bonus is among the highest in GBP
• Best progressive jackpot selection in our top 10
• Strong mobile performance – fully responsive across devices
• Reliable withdrawal processing – payouts arrived as stated

Cons:

• No cryptocurrency payment option
• Withdrawal speeds (24–48 hours for e-wallets) lag behind crypto-first competitors
• Game library (1,500+) is smaller than most rivals on this list

Quick Reviews: Our Testing Notes

Below are our first-hand observations from testing each casino. These notes focus on what stood out – both positive and negative – during actual gameplay and withdrawal testing.

1. SpinHub Casino - Review spinhub– The 15,000-game library is genuinely impressive and doesn’t come at the cost of performance – the platform loads fast and the filtering tools make navigation manageable. Crypto payouts were processed in under an hour across three separate withdrawal tests, which is the most consistent result we recorded. The welcome bonus wagering (35x) is standard for offshore operators. Our main note: the sheer volume of games can be disorienting on first visit – use the provider filter to narrow down quickly.
2. Sankra Casino - Review sankra casino– Sankra feels polished for a relatively new operator. Registration to first game took under four minutes. The slot lobby is well-organised, and we found high-volatility titles from Pragmatic Play and Hacksaw Gaming prominently featured. Crypto withdrawals were confirmed within 90 minutes; card withdrawals took two business days. Credit card deposits worked without any additional friction – no payment declined messages or manual verification prompts.
3. MegawaysVIP Casino - Review megawaysvip – f Megaways™ slots are your format of choice, this is the most concentrated library available outside UKGC-regulated sites. All 500+ titles run with Bonus Buy enabled and no spin delay imposed. Our Solana withdrawal hit our wallet in 22 minutes – the fastest withdrawal we processed across all sites reviewed. The narrow game focus outside Megaways™ is the only meaningful limitation.
4. Allspins Casino - Review allspins– The four-deposit welcome structure is genuinely more player-friendly than single-deposit rivals – it gives you time to assess the platform before committing fully. KYC verification at withdrawal took around six hours, which is reasonable. The interface is one of the cleanest we tested, with no intrusive pop-ups or bonus pressure mechanics. Game library could be broader at 2,000+ titles.
5. Casino Joy - Review casino joy– The MGA licence is the standout credential here – it means a higher standard of game fairness auditing and a clearer dispute process compared to Curaçao-licensed casinos - Curacao casinos. The live casino section is the best-stocked of any site on this list, with consistent table availability across peak hours. Bonus terms are clearly displayed with no buried conditions. The lack of crypto is a limitation for players who prefer anonymous withdrawals.
6. Spin Texas Casino - Review spintexas– The TEXAS25 promo code delivered 25 high-value free spins on Wanted Dead or a Wild at sign-up – confirmed working during our test in April 2026. The welcome package spread across €2,000 + 1,000 spins is the most competitive acquisition offer we’ve found offshore. Bitcoin withdrawals took 47 minutes end-to-end. The EUR/USD native currency means UK players should check their card’s foreign transaction fee before depositing.
7. Wager Tales Casino - Review wager tales– The 400% GEM1 bonus is legitimately one of the biggest first-deposit multipliers in the offshore market – but read the individual GEM code terms before applying each one, as wagering requirements differ. The Pragmatic Play and NetEnt titles run at their full global RTP settings. Support chat responded in under three minutes during our evening test. Crypto payouts took just over two hours, which is consistent with their stated processing time.
8. Britsino Casino - Review britsino casino– The GBP-native currency option is a meaningful practical benefit – we deposited and withdrew in sterling with no conversion fee. The 2,000 free spin count is the highest on this list, though the per-spin value is lower than high-stakes alternatives. KYC verification at withdrawal was handled within four hours. The weekend support response was noticeably slower (around 45 minutes via live chat).
9. Lolo Casino - Review lolo casino– The three-tier welcome package gave us room to explore the platform across multiple sessions without immediately burning through bonus funds. E-wallet withdrawals were processed the same day. The game library at 2,500+ titles is mid-range for this list. Credit card deposits (Visa and Mastercard) worked without friction.
10. Rolletto Casino - Review rolletto– The 4,000+ game library combined with a fully integrated sportsbook makes Rolletto the best all-in-one option for players who switch between casino and sports betting. Cryptocurrency support is the broadest of any site reviewed – Bitcoin, Ethereum, Litecoin, Tether, and Ripple all accepted. The interface is the busiest of the group and takes a session or two to navigate comfortably.
11. Winner Casino - Review winner casino– The progressive jackpot network is clearly a priority – jackpot values and recent winners are displayed prominently on the homepage, and we found more network jackpot titles here than on any other site reviewed. Withdrawals to e-wallets took 36 hours, which is slower than crypto alternatives but arrived within the stated window. The £4,000 maximum welcome bonus makes this worthwhile for players planning a significant first deposit.

What Is GamBlock and How Does It Work?

GamBlock Explained

GamBlock is paid blocking software (approximately £30–50 per year) that installs at the system level on your devices – phones, computers, and tablets – and blocks access to gambling websites across all browsers and apps. It is one of three main self-exclusion tools available to UK players alongside GamStop and Gamban.

Unlike GamStop, which only covers UKGC-licensed operators, GamBlock targets both regulated UK casinos and offshore sites. It does this through a combination of:

• A maintained blocklist of known gambling domains and URLs
• Heuristic detection that analyses site content in real time, identifying gambling-related patterns, keywords, and payment processors – even on sites not yet in its database
• System-level installation that prevents standard uninstallation and is not browser-dependent

The heuristic detection is why brand-new offshore casinos often only remain outside GamBlock’s reach for a short window after launch – once the site accumulates gambling-identifiable signals, the algorithm flags and blocks it.

What GamBlock Blocks

• All UKGC-licensed gambling sites
• Most offshore casino and betting sites
• VPN and proxy attempts to access blocked sites (detected at a system level)
• Mobile gambling apps on devices where it’s installed
• New gambling sites through real-time content analysis

What Can Slip Through

• Brand-new sites in their first days or weeks, before heuristic analysis has processed them
• Sites with atypical technical infrastructure (some crypto-exclusive platforms)
• Sites on devices where GamBlock has not been installed
• Public or shared devices not covered by your personal installation

The casinos listed in our top 10 above are the offshore operators most consistently accessed outside GamBlock’s blocking range in 2026, though detection status can change as the software updates.

GamBlock vs GamStop vs Gamban vs GamCare

These four tools are frequently confused because they serve related but distinct purposes within the UK’s self-exclusion ecosystem.

Feature	GamStop	GamBlock	Gamban	GamCare
Cost	Free	£30–50/year	£20–30/year	Free
Type	National self-exclusion register	Device-level blocking software	Device-level blocking software	Support and counselling provider
Covers UK-licensed sites?	Yes	Yes	Yes	Not applicable
Covers offshore sites?	No	Yes	Yes	Not applicable
Blocks new/unknown gambling sites?	No	Yes (heuristic)	Yes (heuristic)	Not applicable
Removable before period ends?	No (requires fraud)	Very difficult	Very difficult	Not applicable
Works across all devices?	Yes (software-side)	Requires install on each device	Requires install on each device	Not applicable
Best used for	UK-casino self-exclusion	Comprehensive device-level blocking	Comprehensive device-level blocking	Advice, counselling, helpline

GamStop is the simplest starting point – it’s free, covers all UKGC-licensed sites, and requires a single registration. Its limitation is that it does nothing to offshore casinos. For more details, see our guide to non-GamStop casinos - Non gamstop casinos.

GamBlock and Gamban both provide system-level blocking that extends to offshore sites, making them more comprehensive than GamStop alone. The practical differences between the two are minor – device compatibility and interface are the main distinguishing factors. Our separate guide covers casinos not on Gamban - Not on gamban in detail.

GamCare is not a technical block. It is the UK’s leading gambling support organisation, operating the National Gambling Helpline and providing the human infrastructure that connects people to blocking tools, financial restrictions, and professional support. Players searching for casinos not on GamCare - Casinos not on gamcare are typically looking for platforms outside the support network’s affiliated oversight – a separate topic we cover in our dedicated guide.

Why Players Search for Casinos Not on GamBlock

Players reach this page from a range of starting points. Based on the search data around this topic, the most common scenarios are:

• The self-exclusion period has ended. GamBlock subscriptions run for a fixed term chosen at installation – typically 1 month to several years. Players whose period has expired may be looking for offshore options while deciding whether to reinstall or return to regulated UK sites.
• The player was excluded by a family member or third party. In some cases, GamBlock is installed by a concerned partner or parent rather than the player themselves. Players in this situation may have a different relationship to the blocking than those who self-installed.
• Research before installing. Some players are evaluating GamBlock before committing – specifically to understand what it does and does not block, and whether offshore sites would still be accessible.
• Recreational players looking for fewer restrictions. UKGC regulations introduced mandatory stake limits (£2/spin on slots for most players), 3-second spin delays, and affordability checks. Some recreational gamblers who don’t have problem gambling histories seek offshore alternatives specifically to avoid these restrictions rather than to bypass self-exclusion.
• Players who believe they have regained control. Some players who installed blocking during a difficult period now feel their situation has changed and are looking at their options before their subscription period expires.

All of these are legitimate contexts for reading this page. The casinos in our top 10 are reviewed to help readers make informed decisions regardless of their starting point.

Risks of Using Offshore Casinos

Using offshore casinos outside GamBlock and UKGC regulation involves risks that are worth understanding clearly before depositing:

• No UKGC player protections. UK-licensed casinos must follow strict rules on fair bonus terms, segregated player funds, dispute resolution, and responsible gambling tools. Offshore operators are not bound by these rules – the standards of consumer protection vary significantly by licensing jurisdiction.
• Limited dispute resolution. If a UKGC-licensed casino refuses a withdrawal unfairly, you can escalate to an independent adjudicator (the UK’s IBAS or similar). With offshore operators, your recourse is typically limited to the licensing authority (Curaçao, MGA, etc.), which has less enforcement power over operators.
• Variable financial security. Offshore sites are not required to hold player funds in segregated accounts. In the event of an operator insolvency, UKGC-licensed sites have a clearer framework for returning player balances.
• Payment and fraud risk. Smaller or newer offshore casinos may have weaker data security standards or inconsistent payment processing. This is why we recommend starting with well-established offshore operators rather than newly launched sites with no track record.
• Risk of blocking detection changing. A casino accessible outside GamBlock today may be detected and blocked within days or weeks as the software updates. This is unpredictable and outside the player’s control.

The casinos in our top 10 were selected in part for their established track records, verifiable licences, and consistent history of paying player withdrawals. They are not risk-free, but they carry materially less risk than newly launched, unlicensed, or obscure offshore operators.

How to Stay Safe on Unregulated Sites

If you choose to use offshore casinos, these steps reduce your exposure to the risks above:

Verify the licence. Every reputable offshore operator displays its licence number on the footer. Cross-reference that number against the issuing authority’s public registry – Curaçao eGaming, the Malta Gaming Authority, and Gibraltar Licensing Authority all publish searchable licence databases. A logo without a verifiable number is a red flag.

Read the bonus terms fully. Offshore operators are not required to meet UKGC bonus term fairness standards. Check the wagering requirement, the eligible games contribution, the maximum bet permitted while a bonus is active, and the time limit for clearing. Our casino cards include the key figures where we’ve confirmed them.

Withdraw a small amount first. Before making a large deposit, process a small withdrawal to confirm the operator pays out and that the stated processing time is accurate. This is standard practice for evaluating any new casino.

Use payment methods with chargeback options where possible. Credit cards and PayPal offer more recourse than cryptocurrency or bank transfers if a dispute arises. Note that some offshore casinos prefer or require cryptocurrency – if that’s the case, use only amounts you’re comfortable with as a first-time test.

Set your own deposit limits. Offshore sites are not required to provide UKGC-standard responsible gambling tools, but most reputable operators offer voluntary deposit limits in account settings. Use them. Our trusted online casinos guide - Trusted online casinos covers which operators offer the most comprehensive voluntary tools.

Check independent reviews. Search the casino name on AskGamblers, Trustpilot, and Casino Guru before depositing. Look specifically for patterns of withdrawal complaints, account closures without reason, or unresponsive support – not isolated negative reviews.
