Slotornado review: a Curacao casino with no UK licence

Slotornado is an online casino run by Hollycorn N.V. under Curacao licence OGL/2023/176/0095, and it holds no licence from the Gambling Commission. It is therefore not legal for it to offer gambling to people in Great Britain, and it is not part of GAMSTOP. This Slotornado review sets out what that licence position means, not what the site offers.

Who runs Slotornado and where it is licensed

The licence shown for the brand is a Curacao Gaming Control Board number held by Hollycorn N.V. The same company and the same licence sit behind Spinando, so the two casinos share an owner and a regulator. The Australian Communications and Media Authority (ACMA) has issued formal warnings to Hollycorn N.V. for offering illegal online casino services in Australia.

A Curacao licence is permission from Curacao. It does not authorise anyone to serve players in Great Britain.

Slotornado on the GB register: no match

The Gambling Commission register files of 2 November 2026 hold no business, trading name or domain matching Slotornado or Hollycorn N.V. A casino licensed for Britain shows a line saying it is licensed and regulated in Great Britain by the Gambling Commission, followed by an account number you can look up. Our guide on how to check a casino's UK licence walks through that search.

Why the missing licence matters to a British player

Under the Gambling Act 2005, providing remote gambling used in Great Britain without a Commission licence is an offence, wherever the operator is based. For the player, the loss is the set of rules that bind only licensees:

• no link to GAMSTOP, so a national self-exclusion does not reach the site;
• no £5 stake limit per spin on online slots, or £2 for customers aged 18 to 24;
• no 10x cap on bonus wagering and no ban on mixed-product offers;
• no approved ADR provider and no Commission rules to hold the operator to;
• no credit card ban, and payments and disputes sit outside UK law.

The Commission also warns that unlicensed sites can block payouts, set withdrawal limits too high to reach and put personal data at risk.

Already have a Slotornado account?

If you want to stop, asking the operator to close the account is a first step, but no UK body can make an unlicensed operator act on it. Blocking software such as Gamban works across Windows, Mac, iOS and Android, and callers to the National Gambling Helpline can get free access through the TalkBanStop partnership. Registering with GAMSTOP still protects you at every licensed British site.
