The table holds the brands on this licence that this site documents. The Gambling Commission register lists 2 more names against Happytiger ApS on account 57641 — active trading names and live domains, one entry per name — and the Happytiger ApS page prints every one exactly as the register does.
A name on the register belongs to the same licensee — the same company, the same licence conditions, the same self-exclusion. It does not by itself mean there is a live UK site behind it.
How the group is structured
Happytiger ApS holds account 57641. Two of the brands registered to it have a page on this site: Spin King and Happy Tiger. To the Gambling Commission that is one licensee with one set of licence conditions, however many separate websites the customer sees.
This matters in one practical way: a decision made about your account at one of these 2 brands is made by the same company that runs the rest. Verification checks, source-of-funds requests and account restrictions are commonly applied across a licence rather than per brand.
How Spin King compares to its sister sites
All 2 brands listed here answer to the same licensee, so the things set at licence level — complaints routing, funds protection, self-exclusion — are identical across them. What differs is set per brand: the welcome offer, the lobby, the payment methods on the cashier and the look of the site.
Is Spin King safe?
Spin King holds a current Gambling Commission licence under account 57641. That is the part you can verify yourself, and it is the part that matters: a UK licence brings segregated customer funds, a named alternative dispute resolution route, mandatory age verification and GAMSTOP participation.
What a licence does not tell you is how the operator behaves — how fast withdrawals clear, how it handles a disputed bonus, how heavy the verification is. That is worth reading reviews for. What we publish here is the record, not a score.
To check it yourself: open the Gambling Commission public register, search Happytiger ApS, and confirm account 57641 lists Spin King as a trading name. It takes about thirty seconds and it is the only source that cannot be marketed at you.
Sites like Spin King
The closest alternatives are not a hand-picked list — they are the brands that share Spin King's licence. Same operator, same licence conditions, same complaints route, different site.
GAMSTOP and self-exclusion
Because Spin King is licensed by the Gambling Commission, a GAMSTOP self-exclusion blocks it. It also blocks every other brand on account 57641 — Happy Tiger among them — and every other UK-licensed gambling site, in one registration.
This is the reason the "sister site" question matters to people who have self-excluded. You cannot get round GAMSTOP by moving to a sibling brand, and any site advertising itself as outside GAMSTOP is not UK-licensed. We do not list those, and we do not link to them.

Questions about Spin King
Is this a Spin King review?
Not in the usual sense. There is no score, no star rating and no ranking here, because we hold no data that would justify one. What this page is: the Gambling Commission licence record for Spin King, every other brand on the same account, and how to verify all of it yourself in about a minute. If you want an opinion on whether the games pay or the support is quick, read an actual review site — and check this page first to see which other brands that opinion quietly also applies to.
How many sister sites does Spin King have?
One with a page on this site, on Gambling Commission account 57641: Happy Tiger. The register lists 2 more names on the same licence; a registered name is not always a live website.
Who owns Spin King?
Spin King is operated by Happytiger ApS. The licensee is listed on Gambling Commission account 57641.
Is Spin King licensed in the UK?
Yes — account 57641 on the Gambling Commission register. We recheck every account on this site monthly; this one was last confirmed in September 2026.
Does GAMSTOP cover Spin King and its sister sites?
Yes. One GAMSTOP registration blocks Spin King and all 1 sister brand, plus every other UK-licensed site.
Can I claim the welcome bonus at Spin King and its sister sites?
Usually not. Operators normally write the welcome offer as one per customer across the whole licence, so claiming at several brands on account 57641 tends to breach the bonus terms rather than double your money.
If my account is closed at Spin King, can I use a sister site?
Often not. Account decisions are made by the licensee, not the brand, so a closure or restriction on account 57641 is commonly applied across every brand on it.
