CasinOK review 2026: Ryker B.V., a Curacao licence and no UK licence

CasinOK is a crypto-friendly casino and sportsbook launched in 2025 and run by Ryker B.V. under Curacao Gaming Authority licence OGL/2024/1800/1049. It holds no Gambling Commission licence, so it is not licensed to offer gambling to anyone in Great Britain, and this CasinOK review gives no score, offer or link to it.

The brand advertises more than 10,000 games. Reviewers report that its restricted-country list does not name the United Kingdom, but a site leaving the UK off its list does not make it lawful here. Only a GB licence does that.

Point of consumption: why a Curacao licence is not enough

Since November 2014 the Gambling Act 2005 has applied to remote gambling used in Great Britain even when all the operator's equipment is abroad. In practice that means a site serving GB players needs a Commission licence wherever it is based. Providing gambling without one is an offence, and so is advertising unlawful gambling. A Curacao licence regulates the business under Curacao rules; it gives a GB player none of the British protections.

CasinOK promo code and no deposit bonus searches

A large share of searches for this brand ask about a CasinOK promo code, a no deposit bonus or free spins. You will not find them here. The GB rules that keep licensed offers in check, such as wagering capped at 10 times the bonus, clear significant terms and the ban on offers that mix casino with betting, do not bind an unlicensed site, and nobody in the UK can enforce them against it. The same goes for so-called sister sites: shared ownership only matters for GB players when the licence holder is on the register.

If you already hold a CasinOK account

• To stop: close the account through the site's own settings or support, and remove saved payment details. GAMSTOP will not reach CasinOK, because it works only with GB-licensed operators, so blocking software such as Gamban, which GamCare names, is the wider tool.
• To complain: a GB licensee must run a complaints procedure and offer an approved ADR provider after eight weeks or a deadlock letter. None of that applies here, and the Commission does not take up individual disputes. Our complaints guide explains the GB route for licensed sites.
• Your data: the Commission warns that unlicensed sites put personal data at risk, so take care with any account and payment details you have shared.

Confirming a licence on the register

Look for an account number in the footer, then search it on the Commission's public register and confirm an Active status, the casino activity and the site's domain. The steps are in our licence check guide.
