Spinfinite review: a US sweepstakes casino, not GB-licensed

Spinfinite is an American sweepstakes, or social, casino rather than a British one, and it holds no Gambling Commission licence. It is offered in most US states, not in Great Britain. This Spinfinite review explains what the brand is and how to tell it apart from a casino licensed for GB players.

Who owns Spinfinite

The site's footer states:

"Spinfinite.com is owned and operated by Mamba Limited, incorporated in Isle of Man."

The same company runs other sweepstakes brands in the US. Being incorporated in the Isle of Man is a fact about company law; it is not a gambling licence for Great Britain.

How the sweepstakes model differs

Sweepstakes casinos run under US contest rules rather than a gambling licence, which is why the site says no purchase is necessary to play. Independent reviewers describe Spinfinite in the same terms: it operates under sweepstakes contest laws rather than as a licensed real-money gambling site. That legal model belongs to the United States and has no standing under the Gambling Act 2005.

Spinfinite and the Gambling Commission register

The register files dated 2 November 2026 show no business, trading name or domain for Spinfinite or spinfinite.com. No GB licence was found, so the brand is not authorised to provide gambling facilities to anyone in Great Britain. Under the Act, that authorisation is needed wherever a business is based if its facilities are used here.

What a GB licence brings that Spinfinite does not

A Commission licence is what makes UK protections binding on an operator. Licensees must join GAMSTOP, verify age and identity before any play, keep online slot stakes within £5 a spin (£2 for 18 to 24 year olds), cap bonus wagering at 10 times the bonus, refuse credit card gambling and offer an approved ADR service for unresolved complaints. None of these duties attach to a brand with no GB licence. To check any site yourself, see how to check a casino's UK licence; the online casinos UK section covers licensees only.

Keeping gambling in proportion

Gambling, including games that mimic it, is for adults aged 18 and over. Setting limits is covered in our guide to deposit limits and time-outs. If play stops feeling like a choice, the National Gambling Helpline on 0808 8020 133 is free and open 24 hours, and our responsible gambling page lists other help.
