Not every casino offering NOVOMATIC games belongs to NOVOMATIC. The Austrian group develops and supplies gambling technology, and owns or controls businesses that operate gaming venues and online brands. These activities should not be confused.
For British readers, ADMIRAL is the clearest example. Admiral Casino online, ADMIRAL gaming venues on the high street and Greentube's software operations involve different legal entities. Greentube itself is part of NOVOMATIC; a third-party casino hosting Greentube slots is not necessarily part of the group.
This guide maps the companies and casino brands that can be identified from corporate records, regulators and official disclosures. For the wider business, see our NOVOMATIC Group overview.
Which companies and casinos does NOVOMATIC actually own?
The first distinction is between a company, a consumer brand and a product. NOVOMATIC AG is an Austrian legal company. Greentube GmbH is another legal company within the group. Admiral Casino is a name presented to customers, while NOVO LINE identifies gaming products. A casino that buys a game or licences a brand does not become a subsidiary simply by displaying its supplier's name.
The legal relationship also matters. A wholly owned company, a majority-controlled listed company and a business using a licensed trademark are not interchangeable descriptions.
| Name | What it is | Relationship that can be stated | Important limitation |
|---|---|---|---|
| NOVOMATIC AG | Austrian gaming technology and operations company; Firmenbuch FN 69548b | Core legal company of the group | Not the legal operator of every casino featuring its games |
| Greentube GmbH | Austrian digital gaming business; FN 197003k | Austrian register names NOVOMATIC AG as its sole direct shareholder | Other Greentube-branded entities need their own ownership checks |
| Admiral Casino UK | British-facing online casino brand | Operated by Greentube Alderney Limited | Not the same legal person as ADMIRAL's UK venue companies |
| ADMIRAL UK venues | Physical adult gaming centres and related retail activities | Associated with Luxury Leisure, Talarius and RAL legal entities | Trading identity does not identify a single operator for every venue |
| Ainsworth Game Technology | Separately listed Australian gaming equipment company | NOVOMATIC majority stake in dated 2026 shareholder filings | Not a wholly owned brand, and its ASX shares are not NOVOMATIC AG shares |
| NOVO LINE | Gaming machine and game-range label | NOVOMATIC product family | Not established as a standalone casino operator |
This selective map is not a worldwide subsidiary register. A group-directory entry may establish commercial affiliation without proving a direct shareholder or ownership percentage.
ADMIRAL in Britain: online casino, venues and legal operators
Admiral Casino is a UK-facing online gambling service; ADMIRAL Slots is a retail gaming-venue identity. Different companies are responsible for the respective activities, with different regulatory records.
The UK Gambling Commission names Greentube Alderney Limited under account 39050, with admiralcasino.co.uk recorded as an active domain. The online operation therefore should not be attributed to Greentube UK Limited or to a retail arcade company simply because they share group connections.
For the venues, ADMIRAL's own British corporate disclosure names three companies: Luxury Leisure, Talarius Limited and RAL Limited. Companies House identifies each separately. The Gambling Commission's business accounts distinguish Luxury Leisure (1876) from Talarius Limited (1191). The retailer also refers to RAL in its legal notice; that does not justify treating RAL as the registered account holder of a third, separately numbered UKGC account. RAL's Companies House control record names Talarius as a current person with significant control.
| UK activity | Legal entity | Identifier | What this tells the reader |
|---|---|---|---|
| Admiral Casino website | Greentube Alderney Limited | UKGC 39050; Alderney registration 1788 | Identified online gambling operator |
| ADMIRAL retail venues | Luxury Leisure | Companies House 02448035; UKGC 1876 | Separate UK venue and licence record |
| ADMIRAL retail venues | Talarius Limited | Companies House 05382157; UKGC 1191 | Separate retail legal and regulatory record |
| Named in ADMIRAL retail legal notice | RAL Limited | Companies House 01940045 | A distinct legal company; do not invent a separate UKGC account |
| UK group holding activities | Novomatic UK Ltd | Companies House 02816362 | Holding company; not automatically the online casino's direct operator |
| Digital technology and software | Greentube UK Limited | Companies House 10653490; UKGC 48666 | Licensed software business, not the named Admiral Casino online operator |
The regulatory distinction is specific, not absolute. Certain retail-group licensees also hold remote permissions for particular activities. It would therefore be inaccurate to say that Luxury Leisure or Talarius has no remote permissions whatsoever. The defensible point is narrower: Greentube Alderney is the identified operator of Admiral Casino online, while the ADMIRAL venues have their own company and licence arrangements.
Licence details and changing trading names warrant checking against the current UKGC register. Our separate guide to NOVOMATIC markets and gambling licences examines the regulatory side in more detail.
Greentube and its subsidiaries
Greentube is NOVOMATIC's digital gaming business, but the Greentube name covers more than one company and more than one kind of product. It develops online games and supplies gambling software; businesses within its wider operation also provide consumer-facing services. Calling Greentube merely a 'casino brand' loses that distinction.
The Austrian company register supplies a particularly useful ownership starting point. NOVOMATIC AG is shown as the sole direct shareholder of Greentube GmbH (FN 197003k). Greentube GmbH is, in turn, recorded as the sole direct shareholder of Funstage GmbH (FN 258215d) and Platogo Interactive Entertainment GmbH (FN 330672h). These are legal connections, not conclusions drawn from common logos.
In Britain, Greentube UK Limited is a distinct registered company. Its Companies House control record names Greentube GmbH as a person with significant control, and its 2025 statutory accounts describe it as part of the Greentube ownership chain. UKGC account 48666 identifies software-related authorisations, reinforcing why it should not be confused with the online consumer operator on account 39050.
The Alderney operation sits within the broader Greentube business, but the available financial records name Greentube Malta Ltd as an intermediate parent. It would be misleading to draw an unsupported direct 'Greentube GmbH owns 100% of Greentube Alderney' arrow. That precise cross-border chain requires the relevant current Maltese and Alderney records.
Greentube's directory names other local businesses, but cannot establish every direct ownership percentage. Our gaming technology and business model guide explores what the group supplies.
Other NOVOMATIC brands in international markets
The geographical label is essential whenever somebody says 'ADMIRAL belongs to NOVOMATIC'. A single commercial name can appear in distinct national structures, and a transaction in one country need not affect another.
Greentube's official presentation lists online brands and services associated with markets including StarVegas in Italy, Admiralbet in Italy and Spain, Admiral in Romania and Admiral Casino in the UK. These are examples of market-facing names, not a promise that every site is currently licensed for UK customers. A British reader should not assume that an Italian or Spanish service is accessible or authorised in Great Britain.
The social-gaming products GameTwist and Slotpark need their own category. Their virtual-currency entertainment model is not equivalent to a UK real-money gambling licence. Nor should a reader assume that a social-gaming account, a real-money casino account and an arcade loyalty arrangement share the same legal provider or terms.
NOVOMATIC Italia's official corporate map illustrates how local organisation can become more complicated than a single brand. It lists concessionaire, operating and payment businesses under distinct functions:
| Country or market | Names disclosed | What can be established without inventing an ownership percentage |
|---|---|---|
| United Kingdom: online | Admiral Casino; Greentube Alderney Limited | Named consumer brand and UK-facing legal operator |
| United Kingdom: retail | ADMIRAL; Luxury Leisure, Talarius, RAL | Multiple identified venue-related legal entities |
| Italy: concessions | ADMIRAL Gaming Network; Allstar; HBG Online Gaming | NOVOMATIC Italia identifies these within its local concessionaire structure |
| Italy: venue operations | Allstar; Alp; Angelastri; Gambarini | Separate operating functions in the Italian group description |
| Italy: payments | ADMIRAL Pay IP | Payment-services function, not another casino operator by implication |
| Austria: former ADMIRAL operation | ATLAS Group / ADMIRAL Austria | Sold to Tipico in September 2025; no longer presented as a continuing NOVOMATIC-owned Austrian operation |
Allstar appears in more than one Italian function. This is the group's national classification, not a certified share register for every entity.
Is NOVO LINE a casino brand or a game range?
NOVO LINE is a NOVOMATIC gaming-product family, not evidence of a separately incorporated casino operator. Official NOVOMATIC product pages describe game editions, selections and gaming-machine technology. The NOVO LINE Interactive Edition B3, for example, is presented for the British gaming market; GOLDEN LINK editions are further gaming products, not newly acquired casino companies.
People also search for 'Novoline' as a single word. That spelling variation should not erase the distinction between a product label and the operator of a particular website. To establish who runs an online casino, look for its legal terms, jurisdiction and regulator record rather than inferring ownership from the game-range name.
A NOVO LINE cabinet in a venue proves equipment use, not venue ownership.
What has NOVOMATIC acquired or sold?
A company map is only useful if it has a date. Acquisitions can add operating businesses; disposals remove them; a change of registered name may leave the same company intact. Those events should not all be described simply as 'a new NOVOMATIC casino'.
| Event | Date and evidenced outcome | Effect on this company map |
|---|---|---|
| Vikings Casinos, France | NOVOMATIC announced completion of the acquisition on 1 July 2025 | Adds a French casino-operation business to the reported portfolio |
| ADMIRAL Austria / ATLAS Group | Sale agreement announced 8 January 2025; completion announced 8 September 2025 | Austrian ADMIRAL operating business was sold to Tipico; UK and Italian uses of the name are separate questions |
| Kingsbet CZ / Greentube CZ | Czech commercial publication recorded the name change effective 26 June 2026 | Same registered Czech company, IČO 14383012, under a changed name; a rename is not proof of a fresh 100% share acquisition |
| Ainsworth Game Technology | Dated 2026 filings show a NOVOMATIC majority stake; a proposed full takeover ended without completion in February 2026 | The Australian listed company remains distinct; avoid describing it as wholly owned |
The Austrian ADMIRAL disposal is the most important geographic correction. It concerned the specified Austrian business and cannot sensibly be expanded into 'NOVOMATIC sold ADMIRAL everywhere'. Our NOVOMATIC company history and acquisitions article sets out the transaction chronology.
The Ainsworth position also needs precision. NOVOMATIC can control a listed company while outside shareholders still own shares. Dated shareholder filings, rather than a presumed permanent percentage, should anchor our Ainsworth and NOVOMATIC capital guide.
Owned subsidiary, supplier or licensed brand: how to tell
Similar logos can conceal three quite different legal relationships.
A subsidiary has a traceable corporate connection. For example, the Austrian register identifies NOVOMATIC AG as Greentube GmbH's direct shareholder. Where a percentage is material, it should come from the relevant register or filed accounts, not the marketing description 'part of the family'.
A supplier or commercial partner sells games, systems or services to another business. Casinos using Greentube content, including those mentioned in software-integration announcements, may simply be customers or distribution partners. A slot catalogue, content deal or technology logo does not confer equity ownership. This is why a list of 'casinos with NOVOMATIC slots' is not a list of NOVOMATIC subsidiaries.
A licensed brand may be used by a legally separate business. The Swiss ADMIRAL context is an instructive example: ACE SWISS describes relationships involving a separate NOVUM SWISS and Gryphon perimeter, with brand licensing arrangements. That is not sufficient reason to pull every Swiss ADMIRAL-labelled venue into the consolidated subsidiaries of NOVOMATIC AG. A common founder, shareholder connection or trademark licence is a different question from direct ownership by NOVOMATIC AG.
Always ask owner of what: shares, a trademark, machines, a website or a venue lease? These can belong to different parties. See our ownership and management analysis.
How we checked the legal relationships
Our starting point is the legal person rather than the most familiar brand name. Austrian Firmenbuch entries help identify shareholders of Greentube and its Austrian subsidiaries. Companies House filings explain British company identities and control chains. The UK Gambling Commission register identifies the licensee and relevant UK-facing domains. Official company disclosures help locate brands and business lines; dated acquisition announcements establish when a reported transaction closed.
The verification was reviewed on 12 November 2026, using the company reports, regulator registers and official corporate records described above. Not every jurisdiction publishes the same ownership detail, and a person-with-significant-control threshold is not automatically an exact shareholding percentage. Foreign licences and every intermediate holding company have not been independently re-certified here.
The practical answer is straightforward: NOVOMATIC owns gaming businesses and supplies games to many others. Greentube is part of the group; ADMIRAL must be assessed by country and legal operator; NOVO LINE is a product family. Those distinctions are more useful than treating every familiar logo as proof of casino ownership.
