Winningz review: who runs it and where it is licensed
Winningz is run by Simba N.V. under a Curacao licence. It has no Gambling Commission account, trading name or domain.
Our verdict
No GB licenceWinningz is run by Simba N.V. under a Curacao licence and holds no Gambling Commission licence, so it may not serve players in Great Britain.
Worth knowing
- No Gambling Commission licence or register entry
- Operator banned from the Swedish market in June 2025
- Outside GAMSTOP and UK ADR
- No GB stake limits or wagering cap
The only licence the company names for Winningz is Curacao licence LC-76384029, held by Simba N.V., and review sites add one from Anjouan. Neither appears on the GB register, and that is the core of this Winningz review: without a Gambling Commission licence the casino has no permission to serve players in Great Britain.
The company behind Winningz
Simba N.V. is the operator named for Winningz. In June 2025 Spelinspektionen, the Swedish gambling regulator, banned Simba N.V. from the Swedish market. That decision belongs to Sweden, but it is a useful piece of context: the same company runs the brand that turns up in UK search results. For a casino review, who holds the licence matters more than what the lobby looks like, because the licence holder is the party a player would have to deal with if something went wrong.
An empty register search for this Winningz review
The Gambling Commission publishes its register as files of businesses, trading names and domain names. The 2 November 2026 copies contain no match for Winningz, either as a brand or as a domain. There is no account number to look up and no list of approved domains. A business that holds a GB licence must say so on its site with its account number, and that number opens a public entry showing its status, activities and any regulatory action.
What a missing GB licence takes away
| Protection | GB-licensed casino | Site without a GB licence |
|---|---|---|
| GAMSTOP self-exclusion | Compulsory since 31 March 2020 | Not connected |
| Online slot stake limit | £5 per spin, £2 for ages 18 to 24 | None under UK rules |
| Bonus wagering | Capped at 10 times the bonus since 19 January 2026 | No UK cap |
| Disputes | Operator complaint, then free approved ADR after 8 weeks | No UK ADR provider |
| Age and ID checks | Before any deposit or play | Not required by UK rules |
Offering gambling to people in Great Britain without a Commission licence is an offence under the Gambling Act 2005, whatever licence the operator holds elsewhere.
