The third casino on the licence – checked 13 August 2026
SlotsKing sister sites are kwiff and GRP Casino. All three belong to Eaton Gate Gaming Limited, a London company whose UK Gambling Commission account, 44448, includes slotsking.com among its seven listed web addresses. SlotsKing is the quietest of the three: it opens straight into a games lobby, advertised no welcome offer when we visited on 13 August 2026, and appears in the Gambling Commission records only as an address, never as a name. Behind all three sits a £480,305 penalty from December 2022 that the standard account check does not reveal.

An address on the file, not a name
The Gambling Commission records two kinds of identity for a brand: trading names and web addresses. SlotsKing has only the second. Account 44448 carries exactly one trading name, kwiff, while slotsking.com sits among seven web addresses, every one of them marked Active.
Nothing about that is irregular. Filing a trading name is a separate step from filing an address, and plenty of licensees skip it. It does have one practical effect: type SlotsKing into the search and the match comes from the address, slotsking.com, rather than from any name the company has filed.
The account also lists no premises – this is an online-only operation – and its four permissions cover casino play, gambling software, and betting on real and virtual events, though only the casino permission matters to what SlotsKing does. The rest of the record – all seven addresses and what opened at each one when tested – lives on the Eaton Gate Gaming page rather than being repeated here.
Straight into the lobby
www.slotsking.com does not bother with a homepage. Open the address and you are taken directly to a shelf of games, with a Join button in the corner and a menu holding Casino, My Bets, My Profile, Safer Gambling, Promotions and Help.
The browser title reads Play UK Online Casino Games | SlotsKing Online Casino UK. The kwiff casino serves the identical title with its own name in the slot, which is the template showing through: one games platform running under more than one name.
On 13 August 2026 the shelves ran: ten games under Most Played, 32 under New Games, 58 under Slotsking Picks, 100 under Pragmatic Play Picks, 90 table games and 98 live casino tables, plus provider rows for Evolution, Games Global and Inspired. Several tiles carried a NETWORK PROMO flash, and the same flash shows up on GRP Casino tiles – one promotions engine sitting behind both lobbies.
There is no app to look for either. Both app-store rows on the licence belong to the kwiff sportsbook app, which means the browser is the only way in here.
A Jackpots shelf, counted rather than quoted
One row is worth a separate word. The lobby lists 89 jackpot games, and each tile shows a running prize total. Those figures are counters, not prices: they climb as people play, they differ between page loads, and one of them was eight figures long when we looked. That is also why no amount is printed here – any number written down today would be wrong by tomorrow.
The comparison with its sister is the useful part. GRP Casino was running two large jackpot counters at the top of its lobby when the group was checked in August 2026; SlotsKing keeps such figures down on the individual game tiles and leaves the top of the page to the games.
No welcome offer on show
Most casinos put their joining bonus somewhere a visitor cannot miss it. SlotsKing, on 13 August 2026, showed none: nothing on the lobby, nothing in the join form, and no offer small print anywhere a logged-out visitor can reach.
The Promotions entry in the menu does not settle it, because opening it without an account simply returns you to the lobby. Whatever deals exist live behind the login.
Among the three brands on this account that makes SlotsKing the odd one out. kwiff leads with its supercharged-odds gimmick, and the GRP Casino front page promises that new bonus offers are always running. SlotsKing asks you to join on the strength of the games alone – which also means no wagering requirement, no win ceiling and no bonus-balance rules to trip over on day one, because there is no bonus to attach them to.
What joining asks for
The form appeared the moment we clicked Join on 13 August 2026, so this casino is open to new players – worth stating plainly, because a site can stay online long after sign-up quietly stops working. The heading on step one is START WITH THE BASICS, and the stages run like this:
| Stage of the form | What it wants from you |
|---|---|
| Mobile number | A phone number, confirmed by a code the site texts to it |
| Email address | Typed once, in the usual format |
| Password | Entered twice, with a show option on both boxes |
| Consent box | A tick accepting the Terms and Conditions and Privacy Notice |
kwiff and GRP Casino use the same registration engine with the same fields in the same order, so an account at each brand still has to be opened separately, but opening one feels identical across the three.
The December 2022 penalty, and where it is filed
Check this operator the way most people do – by opening its Commission account page – and the counter for regulatory actions shows nothing at all. The sanctions themselves are published in a different part of the Gambling Commission records, and there the picture changes: in December 2022 Eaton Gate Gaming Limited paid £480,305, took a formal warning, and accepted an added condition requiring an independent audit, after failings in money-laundering checks and in looking after customers showing signs of harm.
The sanction names the company rather than any one brand, and it attached to the licence that all three sites now trade under. The full breakdown – the breach paragraphs, the section of the Act behind the warning and the audit deadline – is on the licence page linked above.
A footer that names a different brand
Scroll to the bottom of the SlotsKing lobby and the operator sentence never mentions SlotsKing. It says the site is operated by Kwiff Limited, a company in Msida, Malta, owned in turn by Eaton Gate Gaming Limited, the licence holder, with Kwiff Limited acting as agent under what the sentence calls an umbrella arrangement. The copyright line at the very bottom credits yet another name, Spryme Limited.
One more habit of this lobby: logged out, nothing in the footer works as a link. The terms are reached instead through the tick-box inside the join form, and the document behind that tick-box is the shared group rulebook kept on corporate.kwiff.com – the March 2025 edition, numbered v.37. That website failed for a day in the middle of August 2026 and was answering again on the 13th; the sister pages cover the outage, and the checks that proved it, in detail.
Slots Kingdom is a different casino
Type slotsking into the search and two businesses come back. One is Eaton Gate Gaming Limited, matched through slotsking.com. The other is Jumpman Gaming Limited, account 39175, matched through www.slotskingdom.co.uk. Slots Kingdom, with the extra syllable, belongs to a different company, and nothing on either licence connects the two. If a review or a bonus code mentions Slots Kingdom, it is not talking about this site.
Reading on
The licence record behind everything above – every address, every permission and the whole December 2022 sanction – sits on the Eaton Gate Gaming page. The other casino-only brand has its own write-up at GRP Casino, and the sportsbook that started the whole group at Kwiff.
