Guardian Investigation Reveals Curaçao Casino Network Targeting UK GamStop Users

Investigators from The Guardian and Investigate Europe exposed a sophisticated network of illegal online casinos run by Santeda International, a company based in Curaçao; these platforms aggressively pursued UK gamblers, including individuals who had registered with GamStop—the UK's national self-exclusion scheme designed to block access to licensed gambling sites—by featuring enticing slot games such as Rise of Merlin and Golden Piggy Farm. Sites like MyStake, Velobet, and Goldenbet formed the core of this operation, slipping past restrictions that GamStop enforces on regulated operators while luring players with familiar titles and seamless interfaces. What's interesting is how these platforms operated in plain sight, drawing in users who believed they were safe from temptation after opting out through official channels.

Observers note that Curaçao's licensing framework, often criticized for lax oversight, enabled such entities to function with minimal accountability; data from the probe reveals Santeda International maintained multiple brands under its umbrella, each tailored to evade UK regulations and exploit gaps in enforcement. Take MyStake, for instance, which hosted high-volatility slots promising big wins, or Velobet with its sports betting crossover appealing to a broad audience; Goldenbet rounded out the trio, emphasizing quick deposits and rapid payouts that kept players engaged longer than intended.

And yet, despite the self-exclusion barrier GamStop provides for UK-licensed sites, these offshore operators ignored it entirely, allowing excluded individuals to deposit funds and spin reels without interruption—a loophole that experts have long warned about in unregulated markets.

Figures from the investigation paint a stark picture: between November 2025 and January 2026, these sites attracted an average of 2.3 million unique UK visitors each month, underscoring the scale of their reach into a market bound by strict domestic rules. Researchers tracked this influx using web analytics tools, revealing spikes during peak evenings when promotional banners flashed offers tailored to British tastes—free spins on Merlin-themed adventures or piggy bank jackpots that echoed popular UK slots.

But here's the thing; while licensed operators cap stakes and enforce self-exclusion, these platforms ramped up accessibility with no such limits, pulling in not just casual players but those actively seeking to avoid gambling altogether. One analysis within teh report highlighted how search terms like "slots not on GamStop" drove much of this traffic, with monthly uniques climbing steadily through the winter period as holiday promotions kicked in.

Turns out the numbers didn't lie; 2.3 million represented a significant slice of the UK's online gambling audience, especially considering self-excluded users made up a portion of that crowd, drawn back by the promise of unrestricted play on games they knew well.

At the heart of the operation lay connections to Georgian businessmen affiliated with Upgaming AG, a company that provided backend software and payment processing for the casinos; although Upgaming initially powered slots like Golden Piggy Farm across the network, it abruptly cut ties in March 2026 after journalists' inquiries intensified. This move came swiftly, with public statements distancing the firm from Santeda International, yet traces of their involvement lingered in archived site code and transaction logs uncovered by the probe.

Experts who've dissected similar networks point out that such partnerships often blur lines between legitimate tech providers and shady operators; Upgaming AG, based in Georgia, had marketed its aggregation platform to offshore licenses, enabling seamless integration of games from multiple developers—a service that fueled the rapid growth of MyStake and its siblings. Now, with the split, questions arise about accountability, especially since Curaçao authorities have historically struggled with revoking licenses amid international pressure.

Similar patterns emerge in reports from teh European Gaming and Betting Association, where offshore tech firms enable unlicensed sites to mimic regulated ones, siphoning players from safer environments; in this case, the severance highlighted vulnerabilities when scrutiny hits.

Labour MP Alex Ballinger responded sharply to the revelations, urging immediate intervention from regulators amid mounting evidence of severe financial devastation; cases detailed in the investigation included gamblers losing life savings on Velobet slots, with one particularly harrowing inquest in January 2026 directly linking a suicide to debts racked up on these unlicensed platforms. Ballinger emphasized the human toll, noting how self-excluded users, meant to be protected, instead spiraled deeper into addiction-fueled play.

People often find that offshore sites prey on vulnerabilities GamStop aims to shield, offering credit options and bonuses absent from UK-regulated venues; the inquest, held just months before the April 2026 exposé, ruled the death as contributory to gambling harm from non-compliant operators, spotlighting a tragedy that could have been averted with better cross-border enforcement. And while Ballinger's call echoes ongoing debates, data from the probe shows losses in the millions across affected UK households, with slots like Rise of Merlin cited in personal testimonies of relentless chasing losses.

It's noteworthy that this isn't isolated; observers tracking global trends see parallels in how Curaçao-based networks expand unchecked, but the UK focus here, with its 2.3 million visitors, amplifies the urgency as of April 2026.

Those who've studied offshore gambling know the rubber meets the road in enforcement gaps; Santeda International's model—multiple sites, shared tech, targeted ads—exploited these, pulling in UK traffic despite GamStop's database sharing with licensed firms. Researchers discovered promotional emails bypassing filters, while affiliate networks pushed the sites via UK-facing review portals, creating an ecosystem hard to dismantle.

So what happens next? Upgaming's exit signals potential cracks, yet without coordinated action, similar networks could regroup under new banners; the investigation's timing in early April 2026 keeps the story fresh, with Ballinger's advocacy pushing for tools like IP blocks or payment restrictions on high-risk domains. Cases like the suicide inquest serve as stark reminders, where one family's loss underscores broader risks for the 2.3 million who visited unknowingly or desperately.

Examples abound of players recounting seamless deposits via e-wallets, spins on familiar pigs and wizards, only to face withdrawal hurdles later—a classic offshore tactic documented repeatedly.

The Guardian and Investigate Europe's work lays bare a network that thrived on regulatory shadows, from Curaçao's ports to UK screens, amassing millions of visits while evading self-exclusion safeguards; with Georgian ties severed and political pressure mounting, the path forward hinges on closing these loopholes, ensuring slots like Rise of Merlin stay confined to licensed realms. As April 2026 unfolds, the 2.3 million figure lingers as a call to vigilance, reminding everyone involved that unchecked access exacts a heavy price, from financial ruin to irreversible harm.
