Greentube Alderney Limited: Group Overview
Greentube Alderney Limited has its head office at 5B St Anne's House on Victoria Street in Alderney. It holds 5 Gambling Commission remote licences. Casino and bingo have been active since 1 November 2014, gambling software since 9 December 2014, and general betting on real and virtual events since 9 March 2018. That spread of 5 licences is wide for an operator with 1 consumer site, and the software licence fits Greentube's role as a slot studio.
The register lists 1 domain and 1 trading name under the licence. Its domain is admiralcasino.co.uk and its trading name is admiralcasino, and both are active. No inactive or white-label domains appear, and no premises are listed. Greentube Alderney Ltd therefore runs a single consumer brand in the UK.
Players asking who owns Greentube Alderney Ltd find the answer in the Novomatic Group. Greentube joined Novomatic in 2010 and acts as the group's online arm, while Novomatic is an Austrian gaming company based in Gumpoldskirchen and founded by Johann Graf. Its business-to-business operation moved to Alderney in 2010. Anyone who wants to confirm a licence holder follows the steps in the guide on how to find a casino's operator.
These qualifications are material. A register with 1 active domain under 5 licences shows a narrow consumer footprint and a broad licence scope. It does not show the corporate chain to Novomatic, which comes from group statements and not from the register. The licence holder's record applies to every UK account on admiralcasino.co.uk, whichever game a player opens.
Greentube Alderney Limited History and Key Milestones
The history of the licence holder mixes studio milestones with regulatory ones. Dated milestones below show the main events on record:
- 2000: Greentube takes the name Greentube Internet Entertainment Solutions AG
- 2010: Greentube joins Novomatic and moves its business-to-business work to Alderney
- 1 November 2014: remote casino and bingo licences begin
- 9 December 2014: gambling software licence begins
- 9 March 2018: general betting licences for real and virtual events begin
- 2021: an earlier settlement of £685,000 with the Gambling Commission
- 9 January 2025: settlement of £1,000,000 announced
- 19 January 2026: the UK cap of 10x on bonus wagering takes effect
The register records 1 trading name, and it is active. Admiral Casino is the only name tied to a UK domain. Greentube Alderney Limited therefore offers 1 consumer brand, and this guide profiles it in full.
Greentube Alderney Ltd Revenue and Scale
Greentube Alderney Ltd does not publish a standalone revenue figure, and no sterling figure for the licence holder is available. Scale shows most clearly in the register, which lists 1 domain and 1 trading name. That is a small estate beside the 61 domains held by SkillOnNet.
The player base looks larger than the domain count suggests. Admiral Casino's review page holds 2,754 reviews, which points to a sizeable audience on a single site. These qualifications are material, because a review count says nothing about revenue or active accounts. The register entry is the only dependable measure of licence scope.
Greentube Alderney Ltd Casinos in the UK
The UK offer comes down to 1 brand, Admiral Casino, which carries the Greentube and Novomatic slot catalogue. Table 1 sets out the headline terms before the profile. The brand operates under the Gambling Commission licence as of October 2026.
| Casino | Welcome Bonus and Wagering | Games | Live Casino | Mobile App | Top Feature |
|---|---|---|---|---|---|
| Admiral Casino | 50 free spins on registration plus 50 on a £10 deposit, 1x on winnings, as listings differ | 500 to 1,000+, as listings differ | 20 to 100+ tables, as listings differ | Listings differ | Novomatic classics |
Bonus terms change often. Verify against live terms on each operator's website before depositing. The figures here reflect the terms listed in October 2026.
Admiral Casino
Admiral Casino is the only consumer brand of Greentube Alderney Limited, and it leans on slots from the Novomatic and Greentube catalogue. Listings differ on the welcome offer. A common structure gives 50 free spins on registration plus 50 on a deposit of £10, with 1x on the winnings. Older listings describe a 100% match up to £200 at 35x, which the 10x cap now replaces.
Key terms to check before claiming:
- Free spins on Feel the Flutter and Sizzling Hot Deluxe, as listed
- Wagering of 1x on free spin winnings
- Minimum deposit and withdrawal of £10
- Spins accepted and used within 3 days
Listings put the library at 500 to 1,000+ games and the live lobby at 20 to 100+ tables, so lobby size needs checking on the site. Novomatic classics such as Book of Ra Deluxe, Lucky Lady's Charm Deluxe and Sizzling Hot Deluxe anchor the slots. These qualifications are material. The free spins carry the lowest wagering multiple in this guide, but conflicting listings mean the live offer decides.
The site holds a review score of 3.4 out of 5 from 2,754 reviews, with the newest dated 12 October 2026. About 54 per cent of reviews give 5 stars and 29 per cent give 1 star. Reviewers praise ease of use and promotions, and they complain about few wins, doubts over withdrawals and sudden account closures. The score is a signal and not a verdict.

Greentube Alderney Ltd Casino Bonuses Compared
Welcome offers at the operator come down to 1 brand, so the comparison is between listings and the cap. Admiral Casino lists free spins at 1x on winnings, while older pages quote a 100% match at 35x. The UK cap of 10x on bonus wagering has applied since 19 January 2026, and any listing above 10x on matched funds is out of date.
Take a worked example at the 10x cap. A £50 deposit matched at 100 per cent gives £50 in bonus funds, which makes a £100 balance. The wagering base is the bonus, so 10x on the bonus gives £500 of turnover. At 96.00 per cent RTP the expected cost is about £20, which leaves about £80 at completion.
Free spin winnings at 1x need far less turnover than a matched bonus. These qualifications are material. Expected cost is an average, and the benchmark replaces a multiple that each site sets in its own terms.
Welcome Offers Compared Across the Network
Each line states the wagering position as of October 2026:
- Free spins: 50 on registration plus 50 on a £10 deposit, 1x on winnings
- Older match offer: 100% up to £200, listed at 35x and out of date
- Ceiling for matched funds: 10x on the bonus
Ongoing Promotions and Loyalty Rewards
Reviewers mention a daily free spins game that runs in the app. No loyalty scheme is confirmed for Admiral Casino. Reading the site's own terms before claiming removes the risk of a voided offer.
Greentube Alderney Betting Sites
The licence on record covers general betting on real events and virtual events, active since 9 March 2018. No betting domain appears on the register, so sport is not part of the Greentube Alderney Ltd offer for UK players. Admiral Casino lists no sportsbook. Bingo sits in the same position, with a licence and no domain, so players who want sport or bingo alongside casino look to other groups.
Other Greentube Alderney Ltd Brands
Greentube Alderney Limited groups no other consumer brands under the licence. Its wider role sits in game supply, which the gambling software licence covers. Greentube titles appear at other operators, so players meet the studio's slots on sites that Greentube Alderney Ltd does not run. Groups with several brands are covered in the guide to casino groups and white labels.
Additional Domains on the Greentube Alderney Limited UK Licence
Players on admiralcasino.co.uk play under the Gambling Commission licence, with the same self-exclusion and complaints route as any licensed site. The register shows 1 active domain, with no inactive or white-label entries. Matching the site address to the register confirms that it operates under the licence.
Games and Providers at Greentube Alderney Ltd Casinos
Game content spans slots, table games and live casino, with Greentube and Novomatic slots at the core. Library size runs from about 500 to 1,000+ games, as listings differ. Live content comes from Evolution, with roulette, blackjack, baccarat and game shows such as Crazy Time listed.
Slots and Casino Game Providers
| Game Provider | Admiral Casino |
|---|---|
| Greentube and Novomatic | Yes |
| Evolution | Yes |
| NetEnt | Listed |
| Pragmatic Play | Listed |
| Microgaming | Listed |
The table shows only what listings name, and the lists of studios differ between pages. RTP is published per game, so players read the figure in each game's information panel before staking. The worked example uses 96.00 per cent as a round benchmark.
Live Casino Across the Network
Live tables come from Evolution and include game shows. Listings give the live lobby as 20 to 100+ tables, which is a wide range. Players who want a deep live lobby check the site before joining.
Deposits and Withdrawals
Debit cards work at Admiral Casino, and UK rules ban credit card deposits. The minimum deposit is £10 in most listings. PayPal, Skrill, Neteller, Trustly, Apple Pay and Paysafecard appear beside cards.
Accepted Payment Options Across the Network
| Payment Method | Min Deposit | Max Deposit | Processing Time | Transfer Time | Fees |
|---|---|---|---|---|---|
| Visa and Mastercard debit | £10 | Varies | Credited on deposit | 1 to 3 business days | None listed |
| Apple Pay | £10 | Varies | Credited on deposit | 1 to 3 business days | None listed |
| PayPal | £10 | Varies | Credited on deposit | 1 to 2 business days | None listed |
| Skrill | £10 | Varies | Credited on deposit | 1 to 2 business days | None listed |
| Neteller | £10 | Varies | Credited on deposit | 1 to 2 business days | None listed |
| Trustly | £10 | Varies | Credited on deposit | 1 to 3 business days | None listed |
| Paysafecard | £10 | Varies | Deposit only | Not available | None listed |
For UK players, e-wallets suit the shortest wait among the listed routes, while debit cards suit the widest coverage. The credit card ban applies to every route. Each site's cashier is the reliable check for limits and timing, and the casino withdrawal times guide explains how payout speeds differ across groups.
Greentube Alderney Withdrawal Times and Limits
Listings give withdrawals at 1 to 3 business days, with e-wallets at 1 to 2 days and some pages quoting 24 to 48 hours. The minimum withdrawal is £10, and no fees are listed. Withdrawals return to the deposit method where the cashier allows it.
Identity and address checks apply before an opening withdrawal. Completing verification straight after registration removes the most common cause of delay. Reviewers doubt claims of same-day payouts, so a small test withdrawal removes a common surprise.
Mobile Play and Browser Access
Listings differ on a native app. Some pages describe iOS and Android apps, while others say the mobile site works without a download. A daily free spins game is reported to run in the app only.
Browser Play on Phones and Tablets
Browser play removes download steps and storage use. The cashier and account pages follow the same layout as on desktop. Store ratings are not given here because the app status is not confirmed.
Greentube Alderney Mobile Game Selection
Slots and live tables load in the mobile browser, and library size matches the desktop lobby. Players who want the app-only free spins game install the app where it is offered. Browser users lose that single feature.
Licensing and Enforcement Record
The Gambling Commission regulates Greentube Alderney Limited through 5 remote licences. Register entries show all 5 as active. The site connects to the national self-exclusion scheme (GAMSTOP).
Regulatory Standing Across Greentube Alderney Ltd Brands
Players check the licence and the domain list on the Gambling Commission public register. Matching the site address to that list confirms that it operates under the licence. Status is shown in the table as of October 2026.
| Brand | Licence Body | Licence Status | GamStop Integration | RNG Testing |
|---|---|---|---|---|
| Admiral Casino | UK Gambling Commission | Active domain, October 2026 | Yes | UKGC technical standards |
Gambling Commission Settlements
The public register lists 1 regulatory action against Greentube Alderney Limited as of October 2026. On 9 January 2025 the Gambling Commission announced a settlement of £1,000,000, paid in lieu of a financial penalty, after a regulatory review of the remote licence. It found anti-money laundering failings between September 2022 and June 2023, and social responsibility failings between December 2022 and June 2023.
The findings covered slow review of customer bank statements, linked accounts that were not escalated promptly and source-of-funds checks that were not applied consistently. They also covered large deposits after big wins, document checks that were not always used and vulnerability indicators reviewed late. The settlement included a divestment of £22,113 for socially responsible purposes, plus a contribution to the Commission's costs.
The Commission found no evidence of money laundering or criminal spend with the operator. It noted that Greentube Alderney Ltd put an action plan in place quickly, cooperated fully and accepted the failings early. An earlier settlement in 2021, at £685,000, counts as an aggravating factor.
These qualifications are material. The absence of criminal spend is a positive finding, and the cooperation is on record. Even so, the 2025 payment was higher than the 2021 payment, and the failings covered the same safer-gambling areas that matter to every UK player.
Safety Record of Greentube Alderney Limited
Players on a Gambling Commission licensed site get segregated funds, mandatory identity checks and access to dispute resolution. Safety at Greentube Alderney Limited depends on that licence and on the handling of withdrawals and vulnerable customers. The settlement of 2025 concerned exactly those controls, and the licence holder reported an action plan in response.
Player Protection and Responsible Gambling Tools
Account tools let players set controls without contacting support. BeGambleAware provides free help and advice for anyone concerned about their play. The standard tools are:
- Deposit limits
- Session reminders
- Time-outs
- Self-exclusion
Self-Exclusion and Deposit Limits
Joining the national scheme covers every UK licensed site at once, including admiralcasino.co.uk. Deposit limits and time-outs are set inside the account. The national scheme is the dependable route for players who want to stop across every operator.
Player Feedback and Review Scores
The site holds a review score of 3.4 out of 5 from 2,754 reviews, with the newest dated 12 October 2026. Praise covers ease of use, promotions and friendly staff. Complaints cover few wins, doubts over withdrawals, unsupported fairness claims and generic replies from the company.
These qualifications are material. A score of 3.4 sits near the middle. The split of 54 per cent 5-star reviews against 29 per cent 1-star reviews shows sharply divided opinion.
Strengths and Trade-Offs Across the Network
| Brand | Standout Mechanic | Game Edge | The Trade-Off | Best For |
|---|---|---|---|---|
| Admiral Casino | Free spins at 1x on winnings | Novomatic classics | £1,000,000 settlement | Classic slots |
Admiral Casino gives players a low wagering multiple on free spins, a deep catalogue of Novomatic slots and a minimum deposit of £10. The cost is a narrow estate of 1 brand, conflicting listings and a settlement record. Choosing Admiral Casino comes down to a taste for classic slots, because the group offers no other brand to compare.
Greentube Alderney Ltd Casinos Compared With Other UK Networks
Greentube Alderney Limited is a single-brand operator with 1 active domain on the register, and it leans on its own slot catalogue more than most casino networks. That gives a consistent product and a single complaints route. The comparison below uses stated criteria only:
- Welcome wagering: 1x on free spin winnings, and within 10x on any matched bonus
- Game library: 500 to 1,000+ games, as listings differ
- Mobile access: native app status not confirmed
- Enforcement record: 1 settlement of £1,000,000 in January 2025 and 1 of £685,000 in 2021
The network leads on wagering terms and on the depth of its own slot catalogue. It trails on brand choice, enforcement record and published live casino detail. Players who want several brands under 1 licence compare it with Jumpman Gaming. Readers who compare groups side by side follow the steps in the guide to comparing related casinos.
Final Verdict on Greentube Alderney Ltd Casinos
Admiral Casino is the only brand of Greentube Alderney Limited as of October 2026. It suits players who want classic Novomatic slots with low wagering on free spins, and Book of Ra Deluxe is the main draw. The £1,000,000 settlement, the conflicting listings and the split review score are the main cautions.
This operator suits players who value a studio-led catalogue over brand variety. Completing identity verification straight after registration removes the most common cause of withdrawal delays. Players who want several brands, live depth or sport look to other groups.
