The Guardian's investigation, published in early April 2026, exposes a sprawling network of online casinos operating without UK Gambling Commission licences yet aggressively targeting British gamblers; sites like MyStake, Velobet, and Goldenbet, all run by Curaçao-registered Santeda International, draw in 2.3 million monthly visitors from the UK alone, according to traffic data analyzed by the newspaper.
These platforms, which specialize in slot machine games such as Rise of Merlin and Golden Piggy Farm, slip past essential safeguards like self-exclusion schemes, leaving players exposed to heightened risks of addiction, fraud, and money laundering; observers note how the absence of UK oversight allows these operators to thrive in a regulatory grey zone, pulling in punters who believe they're playing on legitimate sites.
But here's the thing: Santeda International, based in Curaçao, doesn't hold the necessary UK licence, so it evades strict British rules on advertising, player protections, and financial checks; the report details how these casinos use UK-focused marketing, English-language interfaces, and promotions tailored for British tastes, making them indistinguishable from licensed competitors at first glance.
MyStake stands out as one of the biggest players in this network, boasting sleek designs and a library packed with slots from various providers; Velobet follows suit with sports betting alongside casino games, while Goldenbet emphasizes quick payouts and bonuses that lure in casual players, yet all three funnel operations through Santeda's umbrella, sharing backend tech and payment processors.
Data from the investigation reveals these sites collectively attract that staggering 2.3 million UK visits each month—figures that rival some licensed giants—primarily through search engine optimization, affiliate partnerships, and social media ads disguised as harmless entertainment; people searching for popular slots like Rise of Merlin, a fantasy-themed game with expanding wilds and free spins, often land on these unlicensed pages first.
And Golden Piggy Farm? That one's a farmyard slot with piggy bank multipliers and bonus rounds, drawing in players with its cheerful graphics and promise of big wins; experts who've reviewed the platforms point out how such games, optimized for mobile play, keep users spinning longer, especially since there's no mandatory reality checks or session limits enforced by UK standards.
Turns out, Santeda's model relies on Curaçao's lax licensing, which demands far less in terms of player verification or anti-money laundering measures compared to the UK's rigorous framework; this setup lets the network scale rapidly, onboarding thousands of UK accounts weekly without the red tape that licensed operators must navigate.
One of the most alarming findings centers on how these casinos dodge GamStop, the UK's national self-exclusion service that blocks problem gamblers from licensed sites; players who've signed up for GamStop—over 200,000 as of April 2026—find themselves able to deposit and play freely on MyStake or its siblings, since Santeda ignores the database entirely.
Research cited in The Guardian's piece shows this loophole affects vulnerable groups disproportionately; those struggling with addiction continue wagering unchecked, often chasing losses on high-volatility slots without the pop-up warnings or deposit caps that UK-licensed sites enforce under Gambling Commission rules.
What's interesting is the tech behind it: these platforms use geoblocking to appear unavailable in the UK publicly, but savvy users—or those tipped off by affiliates—access them via VPNs or direct links; once inside, GBP deposits flow smoothly through e-wallets and cards, with withdrawals processed in hours, a speed that licensed rivals sometimes can't match due to compliance delays.
Yet this convenience comes at a cost; without UK oversight, there's no independent auditing of games for fairness, no mandatory RTP disclosures, and scant recourse for players hit by technical glitches or bonus disputes—cases where winners report sudden account closures abound in player forums reviewed by investigators.

The lack of protections extends to core vulnerabilities: no robust age verification means under-18s slip through, while fraudsters exploit unmonitored transactions; data indicates these sites process millions in UK deposits monthly, often without the transaction screening that thwarts money laundering on regulated platforms.
Take one case highlighted in the report: a player who deposited thousands via credit card only to have winnings withheld over "verification issues," with no Gambling Commission ombudsman to appeal to; such stories pile up, underscoring how unlicensed status leaves users in the lurch, their funds potentially at risk from opaque operators.
And addiction safeguards? Nonexistent. Slots like Rise of Merlin, with their immersive soundtracks and near-miss features, hook players faster without mandatory breaks; studies referenced show unlicensed sites correlate with higher problem gambling rates, as players bypass self-limits and dive deeper into sessions that stretch into the night.
Here's where it gets interesting: the network's scale amplifies these dangers, with 2.3 million UK visitors exposed monthly to games lacking certified random number generators or independent fairness tests; observers who've tracked similar operations note how this erodes trust in the entire online gambling sector, even as licensed sites play by the rules.
Behind Santeda lurks a web of international ties, including Georgian businessmen who control key shares and decisions; these figures, operating from Tbilisi hubs, oversee expansions that prioritize high-traffic markets like the UK, blending casino ops with betting exchanges for maximum revenue.
Software provider Upgaming powers much of the backend, supplying slots and live dealer tech that's rebranded across the network; according to company records unearthed by The Guardian, Upgaming's integrations enable seamless play on MyStake and kin, complete with customizable bonuses that dangle "100% first deposit matches" to UK newcomers.
So while Curaçao provides the licence facade, Georgian influence and Upgaming's tech drive the engine; this multinational setup, common in grey-market gambling, dodges single-jurisdiction crackdowns, keeping the money flowing despite UK ad bans on unlicensed sites.
People who've followed these patterns know the drill: operators hop domains when heat builds, mirroring IP addresses to evade blocks, a cat-and-mouse game that strains enforcers.
In response to the exposé, UK MPs from across parties have ramped up calls for tougher regulations; figures like Labour's Carolyn Harris, a vocal gambling reformer, urge the government to close offshore loopholes, potentially via expanded IP blocking and affiliate penalties as outlined in ongoing Gambling Act reviews.
Conservative voices echo this, pushing for GamStop's reach to extend extraterritorially or for payment providers to flag unlicensed deposits; with April 2026 marking a pivotal moment in the white paper implementation, these demands gain traction amid rising problem gambling stats—over 400,000 adults affected, per recent surveys.
That's the reality: without swift moves, networks like Santeda's will keep ballooning, siphoning revenue from licensed operators while endangering players; enforcement bodies now monitor these sites closely, but MPs stress that legislation must evolve faster than the tech.
The Guardian's probe into Santeda International lays bare a thriving unlicensed ecosystem preying on UK slot enthusiasts; with 2.3 million monthly visitors bypassing GamStop and protections on platforms like MyStake, Velobet, and Goldenbet—fueled by games such as Rise of Merlin and Golden Piggy Farm—the stakes couldn't be higher as MPs press for regulatory clamps in April 2026.
Ultimately, this story spotlights the fragility of borders in digital gambling; while Curaçao bases and Georgian ties sustain the operation, bolstered by Upgaming, the push for enhanced UK safeguards signals a turning point, one where players' safety might finally trump offshore profits.
