Cosmobet
Licence status, GamStop coverage and any publicly documented issues for Cosmobet, with sources. A listing is a record, not an allegation of wrongdoing.
Platform and background
Cosmobet is an offshore online casino and sportsbook that launched in 2023 as one of the newer brands in the Santeda International stable. It runs a crypto-friendly model, accepting both traditional and cryptocurrency deposits, and offers real-money slots, live dealer tables, virtual sports and esports markets. The brand markets itself heavily through affiliate channels, and a cluster of look-alike 'official UK' mirror domains and review pages promote it to British searchers, several of them using 'not on GamStop' framing. None of this changes the underlying position: Cosmobet is an offshore Curacao brand, not a UK-regulated operator, and the consumer protections that come with a UK Gambling Commission licence do not apply to players who use it.
Ownership and the Santeda group
Cosmobet is operated by Santeda International B.V., a company registered in Curacao (company registration 151296), with Santeda International Limited, a Cyprus-registered entity, acting as its EU and EEA representative. The same group sits behind a family of sister brands, most prominently Mystake, alongside Goldenbet, Velobet and Rolletto, with newer names such as Donbet and LocasBet also linked to the network. This group structure matters for anyone trying to recover money, because reporting and complaints suggest the operator moves players between sister sites, and industry coverage indicates the underlying Curacao licensing entities have been reorganised, with several Santeda brands reported to have shifted to a company called GTW B.V. as scrutiny has grown. Identifying the correct legal entity is therefore an important first step in any complaint.
Licence and UK position
Cosmobet operates under a Curacao licence rather than any UK Gambling Commission authorisation, so it is not UKGC-regulated and is not covered by GamStop, the British national self-exclusion scheme. Operator terms and review listings cite a Curacao Gaming Control Board licence numbered OGL/2024/1798/1048 issued to Santeda International B.V., though the wider Santeda network has been reorganising its Curacao licence entities, so Clinton & Co treats this number as current but subject to change and recommends confirming the live entity before acting. On UK access the picture is mixed. Reputable review listings such as AskGamblers show the brand as restricted in the United Kingdom, yet UK players continue to report that they can register and deposit, and the GAMRS report describes active UK-facing promotion. In practice this is a brand whose terms point away from the UK while UK players still report access, and either way the UKGC's protections do not apply.
What players report
Across casino.guru, AskGamblers and public review platforms, a recurring set of complaints attaches to Cosmobet. Players report that accounts were closed and winnings confiscated after bonus play, often citing unspecified terms violations, and that identity checks under KYC were left in progress for one to two weeks or more while withdrawals stayed blocked. More seriously, one player reports asking Cosmobet for self-exclusion on 25 May 2025 because of a gambling problem and says the casino kept accepting deposits and sent VIP offers, with losses passing EUR 60,000. These accounts are player allegations rather than proven findings, but the pattern, confiscated winnings, stalled KYC and an ignored self-exclusion request, is exactly the kind of harm UK players raise with us.
The GAMRS report and what UK players can do
In December 2025 GAMRS, the Gambling Industry Accreditation, Monitoring & Registration Service, published a report co-authored with DealMeOut that names Cosmobet as one of five Santeda International brands forming a UK-facing offshore network said to generate over GBP 2 billion, roughly USD 2.7 billion, a year. The report alleges the network leans on 'not on GamStop' affiliate marketing aimed at self-excluded gamblers, deploys aggressive retention tactics and migrates users between sister sites after they try to stop. A survey of UK respondents reported combined losses of about USD 322,500 on the flagship brand, Mystake, alone. If you are a UK player who lost money to Cosmobet, particularly where a self-exclusion request was ignored or where no affordability or KYC checks were applied before losses mounted, the route is to raise a formal complaint through the operator's own process and, where appropriate, to escalate with the support of regulated legal partners. Keep your account history, deposit records and any self-exclusion or support correspondence, as this evidence is central to building a case.
What the record shows
Named in the December 2025 GAMRS report (co-authored with DealMeOut) as one of five Santeda International brands (alongside Mystake, Goldenbet, Velobet and Rolletto) said to form a UK-facing offshore network generating over GBP 2 billion (around USD 2.7 billion) a year and alleged to use 'not on GamStop' marketing aimed at self-excluded UK players. The detailed UK-targeting and self-exclusion case study in the report centres on the flagship brand Mystake.

SourceWhat the licence requires
Cosmobet is regulated by Curaçao Gaming Authority (CGA) under licence OGL/2024/1798/1048, and it holds no UK Gambling Commission licence, so GamStop and the UK dispute-resolution framework do not apply. Read more on how Curaçao casino law works.
If you are trying to recover money
Because Cosmobet is licensed in Curaçao and not by the UK Gambling Commission, no UK adjudicator can order a refund, so recovery runs as a claim built on Cosmobet's own complaints process and contractual terms, taken forward with a regulated legal partner where the evidence supports it. Preserve your account evidence first, then see how gambling-loss recovery works, the evidence you need to recover losses, and how to escalate a casino complaint.

Common questions about Cosmobet
Can I get my money back from Cosmobet?
Possibly. Cosmobet is licensed in Curaçao, outside the UK system, so no UK adjudicator can order a refund. Recovery instead works through the operator's own complaints process, the evidence your payment history supports, and where appropriate a regulated legal partner. The right route depends on your evidence, and our initial assessment is free and confidential.
Who operates Cosmobet, and is it licensed?
Cosmobet is operated by Santeda International B.V., licensed in Curaçao, under licence OGL/2024/1798/1048. It is recorded as licensed under Curacao Gaming Control Board (CGCB). The brand has operated since 2023. It sits outside GamStop, so a GamStop self-exclusion does not block it.
Does Cosmobet accept UK players?
Cosmobet does not list the UK as an accepted market. T&Cs and review listings restrict the UK, but UK players report access; the GAMRS report alleges active UK targeting via 'not on GamStop' marketing. Not UKGC-licensed. Whichever applies, the licence in force when you played is what shapes the routes open to you.
Is there anything documented on file about Cosmobet?
Our research records 3 reported allegations for Cosmobet, each with its issuing body and a source you can check. A listing is a record, not proof of wrongdoing, and every case turns on its own evidence.
What should I do if Cosmobet will not pay out or has frozen my account?
Preserve the evidence first: screenshot your balance, the stuck withdrawal, chat transcripts and emails, and save the terms as they read today. Then make one formal written complaint and escalate to the right authority or a regulated legal partner. Avoid closing the account or accepting a partial settlement before you have taken advice.
Will Cosmobet know I contacted Clinton & Co?
No. Nothing is sent to any operator without your written consent. The first an operator hears of your case is a formal complaint you have approved.
Is Cosmobet holding your money?
The sooner the evidence is preserved, the stronger the file. Our initial assessment is free and strictly confidential.
