Short answer
The Kinghills Casino pages name no sister brands and no operator. The one concrete link is with Ninewin Casino: the terms, bonus rules, policies, welcome pack and app page are the same, and Ninewin's fairness page mentions kinghills.com. That points to a shared platform. It does not, by itself, prove common ownership.

Kinghills Casino sister sites are not listed anywhere on the casino's own pages. There is no footer line saying "part of a group", no brand list and no company name to look up. That absence is itself a finding. What can be said comes from comparing the Kinghills Casino documents with those of a casino that looks like a relative, and that comparison is the subject of this page. It was done on 22 October 2026, from a UK connection, with the terms dated 1 November 2024 in hand.
What Kinghills Casino says about sister brands
Nothing. The terms refer only to "the Company", without a name, a registration number or an address. The About page, the policies and the footer carry no mention of other casinos. The footer line reads as a brand copyright for kinghills.com.
A partner e-mail address for affiliates does appear, under the name of an affiliate programme. That is a marketing contact, not an operator, and it tells us nothing about ownership.
Kinghills Casino sister sites: the Ninewin match
Among Kinghills Casino sister sites, the closest relative is Ninewin Casino. Its terms, bonus rules and policies are the same documents with a different brand name, in the same version.

On the promotions page above, the welcome pack is the one Ninewin shows too: three deposit bonuses of up to €500 each, with 150 and 100 free spins on the first two.
| Area | Kinghills Casino | Ninewin Casino |
|---|---|---|
| Terms version | 1 November 2024 | the same |
| Restricted countries | UK, USA, Spain, France and others | the same |
| Wagering | 40x | the same |
| Slot bet cap with a bonus | €5 | the same |
| Win cap | 10 times the bonus | the same |
| Withdrawal processing | up to 72 hours | the same |
| Minimum withdrawal | €50 | stated as a range, €50 to €120 |
| App page | store-style page, name changed | the same page |
Compared line by line, the two read as one product under two names. The withdrawal minimum is the one row where the wording differs.
The one cross-reference
The only link we found between the two runs from Ninewin to Kinghills, not the other way. Ninewin's fairness page mentions kinghills.com in a sentence about fair casinos run by "the Company" and names two companies in the same place. On the Kinghills side, the same sentence has been rewritten to say only that it is run by the Company.
We do not name those two companies here as the operator of Kinghills. Kinghills does not name them, and a mention on another casino's page is not a licence record. If you want the operator, ask Kinghills live chat for the company name and the licence number in writing; that request is among the checks on our Kinghills Casino review.
Where Kinghills and Ninewin differ

The FAQ page above lists the topics Account, Bonus, Deposit, Verification, Withdrawal, Challenges, Games and Sportsbook. Ninewin's equivalent page uses "Adventures" where Kinghills says "Challenges", one of several small edits.
- Currency tables. Kinghills adds tables of limits in many currencies to the bonus terms, including CAD, NZD, CHF, PLN, MXN, GBP, LTC and BTC.
- Rakeback. The Kinghills terms state a maximum of 25%.
- Accounts. Kinghills spells out that only one account is allowed per household, device and IP address.
- Self-exclusion. The Kinghills responsible gaming policy has a separate Self-Exclusion section with a permanent option requested by e-mail.
- Home page FAQ. Ninewin has a questions block on its home page that Kinghills does not.
- Affiliate programme. The two use different partner programme names.
These are edits at the edges. The structure of the documents is shared.
Why the Ninewin match is only a clue
Two casinos can hold identical documents for several reasons: one operator running two brands, a platform provider licensing a ready-made product, or one site copying the other. The documents alone cannot tell these apart. What the match does give a reader is practical: whatever you learn from the terms of one, from the version date to the restricted list, tells you what to expect of the other. The match also explains why the questions about the operator come back unanswered on both sites in the same way.
What a shared platform means for you
Three practical points follow from it.
- The rules travel. A restriction, a wagering rate or a verification step you read about on one site applies to the other. The United Kingdom is restricted in both.
- Experience reports transfer only partly. A review of Ninewin payouts says something about the platform, but Kinghills limits depend on rank and method. We read documents, so we cannot report payouts for either.
- No named company means no named complaint route. Both sites send complaints to an e-mail address and, after that, to a body "listed on the Website". If that list is missing on one, it is missing on the other.
Questions that stay open
| Question | Status on 22 October 2026 |
|---|---|
| Who operates Kinghills Casino? | not named, only "the Company" |
| Which regulator and licence number? | not named |
| Does Kinghills belong to a group of brands? | not stated by the casino |
| Does Kinghills share a platform with Ninewin? | yes, by the documents |
| Do the two share an owner? | unconfirmed |
How to test a claim about Kinghills Casino sister sites
Lists of "sister brands" circulate on review sites. Three checks separate a statement that can be tested from one that cannot. First, does the casino itself print a company name in its terms or footer? Kinghills does not. Second, does a licence record, with a number, name that company and the brand? None is shown. Third, can the claimed relative be matched by documents? Ninewin can, in part, which is why it is the only one on this page. Anything else is a guess until those three answers exist, and live chat can be asked for the first two in writing.
What we do not claim
On the subject of Kinghills Casino sister sites, we do not say Kinghills and Ninewin have the same owner. A platform provider can supply identical documents to several unrelated casinos, and identical text can be copied. We also do not rely on third-party review sites for ownership, because their claims are not checked against a licence record. Anything said about a larger group of brands, by us or by anyone else, stays unconfirmed until the casino prints a company name and a licence number.

Kinghills Casino questions and answers
Bearing 023°What are the Kinghills Casino sister sites?
The casino names none. Ninewin Casino shares its terms, policies, bonus pack and app page, so it is the closest relative we found.
Bearing 090°Does Kinghills Casino belong to the same company as Ninewin?
We cannot say. Kinghills names no company. Ninewin's fairness page names two companies beside kinghills.com, but Kinghills replaces that wording with "the Company", so we do not state either as its operator.
Bearing 157°Are Kinghills and Ninewin the same casino?
They are not identical. The currency tables, the rakeback maximum, the account rule and the self-exclusion section differ. The core documents are the same.
Bearing 224°Why does it matter who the sister sites are?
A casino with no named operator gives you no company to hold to account. A shared platform means the same rules apply on both sites, including the UK restriction. See is Kinghills legit.
Bearing 291°Can a UK player use a Kinghills sister site?
The United Kingdom is restricted in the terms the two sites share. See Kinghills and the UK.
