Kwiff Sister Sites
The operating company, the brand family, and what shared licensing actually means for the customer's experience and exclusion choices.
The operating company
Kwiff is operated by Eaton Gate Gaming Ltd, a British company registered in 2015 and holding UK Gambling Commission licence number 48707. The company is owned by a private investment vehicle and has, throughout its operating history, been a single-brand operator.
This is unusual on the modern British market, where the larger operators (Entain, Flutter, 888) control portfolios of a dozen or more brands trading under common licensing. Kwiff is, in 2026, still a single-brand operation. There is no formal "sister site" within the Eaton Gate group.
What "Kwiff sister sites" actually refers to
The term is most often used loosely on review sites to refer to other UKGC-licensed casinos that share characteristics with Kwiff, similar slot libraries, comparable promotional structures, similar regulatory standing. By that loose standard, the closest editorial comparators are:
- SpinYoo, operated by White Hat Gaming. Comparable slot library, similar British-market positioning.
- Casumo, distinct gamified style. Comparable studio mix.
- Mr Vegas Casino, operated by Videoslots Ltd. Similar focus on RTP transparency.
- Bzeebet, comparable sportsbook-led model with feature-driven promotions.
None of these are formal sister sites in the corporate sense. They are simply the casinos a Kwiff customer is most likely to enjoy if they want a comparable experience elsewhere.
Self-exclusion and GAMSTOP
Kwiff is connected to GAMSTOP, the UK's national self-exclusion scheme. A GAMSTOP exclusion applied to any UKGC-licensed brand applies to Kwiff automatically. This is mandatory for every UKGC-licensed operator and is the practical reason that "sister site" research matters less in the British market than the offshore market: regulated self-exclusion is centralised.
A player who has self-excluded from Kwiff cannot register a new account anywhere in the UKGC-licensed market for the duration of their exclusion. The unregulated market is a separate matter and one we would not recommend any customer engage with under any circumstances.
What this means for the customer
The single-brand nature of Eaton Gate Gaming means the Kwiff customer experience is concentrated rather than diluted. The operator is not running a portfolio of brands competing for marketing budget, every product decision affects every customer. For the patient player, this is a feature, not a limitation.
The honest answer about Kwiff sister sites
Kwiff has no sister sites in the way affiliate pages usually mean it. Eaton Gate Gaming Ltd operates the Kwiff brand and only the Kwiff brand on its UKGC licence. The lists you see elsewhere titled "Kwiff sister sites" are almost always affiliate constructions: collections of unrelated casinos that share nothing with Kwiff beyond accepting UK players, assembled to capture the search term. We publish this page mostly to say so plainly.
What Kwiff does have is structural relatives: other app-first UKGC operators competing for the same punter. If what you like about Kwiff is the licence, the app polish or the gimmick economy, those are the axes to shop along, and the comparison table below is built on them rather than on invented corporate kinship.
If you are shopping for a second book
Run the same checks we run: UKGC licence number resolving on the Commission register, GamStop participation, withdrawal timings from user reports rather than the operator's own page, and whether the signature feature survives contact with its terms. A mechanic is only as good as its fine print; Kwiff's supercharge paying cash with no wagering is the bar to clear.
Kwiff vs the operators punters actually compare it with
| Operator | Licence | The comparable hook |
|---|---|---|
| Kwiff | UKGC (Eaton Gate Gaming) | Random odds/spin supercharges, cash-paid |
| Betfair | UKGC | Exchange betting, depth over gimmicks |
| LiveScore Bet | UKGC | App-first, media-integrated |
| Midnite | UKGC | Modern app, esports leaning |
| BetMGM UK | UKGC | Big-brand promos calendar |
There is exactly one Kwiff. Judge it on its own terms.
See Kwiff first-handFrequently asked questions
Does Eaton Gate Gaming run any other casinos?
No. Its UKGC licence covers the Kwiff brand alone, which is why genuine sister sites do not exist. Treat any list claiming otherwise as affiliate filler.
Is there a Kwiff casino-only sister brand?
No. The casino and sportsbook live inside the same Kwiff account, app and wallet, under the same licence.
Is this the official Kwiff website?
No. This is an independent affiliate guide and cannot access or manage a Kwiff account.
How can I verify Kwiff's licence?
Use the Gambling Commission public register and check Eaton Gate Gaming Limited account 44448 and its active kwiff trading name.
Can information on this page change?
Yes. Product features, promotions and account procedures can change, so confirm important details in the live operator terms.

Yes. Gambling services in Great Britain are restricted to people aged 18 and over.
