UK-Facing Crypto-Casino Network Goes Dark for 20 Hours as Slot Suppliers Exit

Mystake, one of the largest UK-facing crypto-casino networks blinked offline for roughly 20 hours last weekend after several B2B game studios pulled their slots from its sites.

• Key Takeaways:
• • Mystake and sister sites went dark for about 20 hours on June 14 after B2B slot suppliers pulled their games.
• • GAMRS ties the ~$4.7B Santeda network to UK black-market play, with 64% of revenue British.
• • Sites returned within a day with thinner libraries as crypto payment rails kept the network alive.

Crypto Rails Outlast the Game Suppliers

Mystake, Goldenbet, Donbet, Velobet, Cosmobet, Freshbet and Rolletto – brands long linked to Curaçao operator Santeda International B.V. – went dark on the evening of Sunday, June 14, some showing 404 errors and others stripped of their game libraries, as reported by Next.io. Research body GAMRS said the blackout followed several B2B slot suppliers pulling their products after sustained pressure to stop serving unlicensed operators.

On X, Mystake called the disruption “scheduled maintenance.” GAMRS chief executive Jordan Lea framed it differently, telling reporters that for “20 or so hours, users were left not knowing if their funds were gone or not,” and claiming the sites were down on mobile across the UK and most of Europe. Most brands were back the next day, though – by his account and others – not all of their previous games returned.

The episode showed how dependent these operators are on third-party slot content – and how little else the takedown touched. The sportsbook and the crypto payment rails kept running; within a day, Mystake was promoting World Cup betting again.

GAMRS has tracked the network for months. Its research estimates the Santeda group turned over roughly $4.7 billion (£3.51bn) in 2025 – about $1.6 billion (£1.2bn) on Mystake alone – with some 64% of revenue from UK consumers and around $2.7 billion (£2.02bn) deposited by British players a year. The brands lean on “not on Gamstop” affiliate marketing aimed at self-excluded gamblers; 96 UK respondents reported losing about $322,500 (£241,152) on Mystake. As scrutiny grew, the operator moved its Curaçao license from Santeda to a vehicle called GTW B.V., then dissolved both.

Pressure on the suppliers and processors that serve these sites tends to push operators further offshore rather than shut them down – which is why, a day after going dark, Mystake’s catalogue was thinner but its doors were open.
