UK-facing crypto casino network offline for 20 hours

Mystake and several related UK-facing crypto-casino sites went offline on the evening of June 14 and remained inaccessible for about 20 hours after multiple B2B slot suppliers removed their games. Affected brands include Mystake, Goldenbet, Donbet, Velobet, Cosmobet, Freshbet and Rolletto, which have long been linked to a Curaçao operator.

During the outage some domains showed 404 errors while others stayed online with their slot libraries stripped. Sportsbook functions and the crypto payment rails that process deposits and withdrawals continued operating during the disruption. Mystake posted on its social channel that the interruption was “scheduled maintenance.” GAMRS chief executive Jordan Lea described users as left “not knowing if their funds were gone or not” and reported the sites were inaccessible on mobile across the UK and much of Europe.

Most brands resumed service within a day, though many returned with smaller game catalogs than before. Within a day of the outage Mystake was promoting World Cup betting while its slot library remained reduced.

Research group GAMRS estimates the group linked to the Curaçao operator generated about $4.7 billion in turnover in 2025, with roughly $1.6 billion on Mystake alone. GAMRS reports about 64% of that revenue came from UK customers and estimates British players deposited about $2.7 billion with the network that year. The group also reported affiliates using “not on Gamstop” messaging and said 96 UK respondents reported losing a combined £241,152 on Mystake.

GAMRS says the operator moved its Curaçao licence from one corporate vehicle to another, registering under GTW B.V., and later dissolved both companies. GAMRS and industry observers noted earlier pressure on suppliers and payment processors serving these sites.

The UK Gambling Commission recently advertised a senior “Head of Illegal Markets” role with a £65,000 salary. The outage was noted by researchers and industry observers alongside regulatory activity focused on unlicensed offshore gambling and sites that accept crypto payments.
