Greentube is a UKGC-licensed slot studio whose founding date and headquarters are not publicly disclosed, best known for its Lucky Lady's Charm franchise and magic-themed Video slots. Their UK catalogue includes 4 titles featured on ALHCO, headlined by Lucky Lady's Charm Deluxe 10, Luck of the Dead, and Lucky Lady's Charm Deluxe. The house style leans heavily on classic charm-symbol structures with a contemporary video-slot presentation.
About Greentube
Company history
Greentube is a digital gaming division operating under the Novomatic Group, one of the largest land-based and online gaming conglomerates in Europe. While specific founding dates and headquarters details are not publicly disclosed, Greentube operates as Novomatic's dedicated online and mobile development arm, translating the group's long-standing cabinet heritage into browser and mobile-compatible titles. Their most recognisable contribution to the online market has been faithfully converting Novomatic's physical slot library - including the enduring Lucky Lady's Charm series - into certified online releases, a process that has introduced decades of land-based familiarity to regulated digital markets including the UK.
What makes them different
Greentube's clearest distinction is its position as the online conversion specialist for Novomatic cabinet titles, giving it a legacy audience that rivals built from scratch cannot replicate. Compared to studios like Play'n GO or Pragmatic Play, which develop original IP with complex multi-level bonus structures, Greentube's catalogue tends to favour streamlined mechanic sets - scatter-triggered free spins, expanding wilds, and multiplier stacks - rather than intricate pick-bonus or megaways formats. That conservatism is also the studio's most honest weakness: with only 4 titles represented on ALHCO and a Magic concentration that dominates the visible portfolio, the range is narrow and the thematic variety limited compared to larger studios producing 100-plus titles annually.

Signature Mechanics & House Style
Across the 4 titles in our ALHCO catalogue, Greentube demonstrates a consistent preference for mechanic simplicity over feature complexity. The studio's approach is built around a small set of clearly defined tools that recur across titles rather than introducing novel systems in each release. In our testing, the following mechanics characterise the Greentube house style:
- Scatter-triggered free spin rounds appear across the catalogue, with Lucky Lady's Charm Deluxe 10 supporting up to 4,000x maximum win potential during its bonus phase. - Expanding or sticky wild symbols are used to fill reel columns during free spins, creating extended winning evaluations without secondary pick mechanics. - Multiplier increments during bonus rounds are a recurring feature, though the public paytable does not disclose precise per-spin multiplier scaling for every title. - The Lucky Lady's Charm Deluxe carries an exceptional maximum win ceiling of up to 27,000x, making it the statistical outlier in a portfolio where most titles sit considerably lower. - Retrigger eligibility during free spin rounds is indicated in game rules, though specific scatter-count requirements for retriggering are not uniformly disclosed across all paytables.

Lucky Lady's Charm Deluxe 10
Released in November 2018, Lucky Lady's Charm Deluxe 10 is the ten-payline iteration of Greentube's flagship franchise, carrying an RTP of 96.02% and a maximum win of up to 4,000x. It retains the four-leaf clover, horseshoe, and wishing well symbol set that defines the series, delivering a free spins round with sticky wild behaviour. For players familiar with the land-based Novomatic cabinet, this version provides a close digital equivalent without significant mechanic inflation. See our full Lucky Lady's Charm Deluxe 10 review for detailed paytable analysis.
Luck of the Dead
Launched in May 2025, Luck of the Dead is Greentube's most recent entry in our catalogue and their sole high-volatility title, carrying an RTP of 94.98% and a maximum win of up to 1,000x. Its Día de los Muertos aesthetic marks a deliberate departure from the studio's magic-symbol defaults, introducing skull and floral iconography alongside a more compressed payout structure than the Lucky Lady's titles. At 94.98%, the RTP sits below the UK industry average of approximately 96%, a tradeoff players should factor into session planning. Full mechanic notes are at Luck of the Dead review.
Lucky Lady's Charm Deluxe
The 2019 Deluxe variant at Lucky Lady's Charm Deluxe holds the portfolio's highest maximum win ceiling at up to 27,000x, with an RTP of 95.13%. Its volatility classification is not publicly disclosed. The extreme upper win potential makes this the mathematically widest-ranging title in Greentube's ALHCO presence, though players should understand that a 27,000x ceiling reflects rare-outcome modelling rather than typical session behaviour. Its paytable shares the classic charm iconography of its sibling titles, making it recognisable to returning players while offering a meaningfully different risk profile.
RTP & Volatility Range Across the Portfolio
Greentube's 4-title ALHCO portfolio spans an RTP range of 94.98% to 96.02%, with the top of that range - Lucky Lady's Charm Deluxe 10 at 96.02% - aligning closely with the UK market average of approximately 96%. The bottom of the range, Luck of the Dead at 94.98%, sits notably below that benchmark, which is a meaningful consideration for UK players managing bankroll across longer sessions. Volatility data is confirmed for only 1 title (Luck of the Dead, classified as high), while the remaining titles do not publicly disclose volatility ratings. For an explanation of how volatility affects session variance and return frequency, see our Slot Volatility Explained. Maximum win potential across the portfolio ranges from 1,000x to 27,000x, representing a wide spread despite the small catalogue size.
