Greentube supplies HTML5 slots reimagined from NOVOMATIC's land-based catalogue, including Book of Ra deluxe, Sizzling Hot deluxe and Lucky Lady's Charm, alongside progressive families Diamond Cash, Diamond Link and Diamond Mystery.

Greentube is headquartered in Vienna, Austria, as the Digital Gaming and Entertainment division of the NOVOMATIC Group. The company operates through fourteen subsidiaries worldwide, including offices in Malta, the UK, Gibraltar, Alderney, Slovakia, Serbia, the Netherlands, the United States, Luxembourg, Slovenia, Greece, Canada and India.
Greentube traces its roots to 1998, when it launched the 3D sports title Ski Challenge. The company was renamed Greentube Internet Entertainment Solutions AG in 2000 and joined the NOVOMATIC Group in 2010, becoming the group's dedicated online and mobile gaming division and growing into one of Europe's leading B2B casino-content suppliers.
Greentube maintains an active social-media presence used to showcase new releases and engage players, including its 2026 World Trophy fan-voted tournament that crowned Firecracker Frenzy: Empress Wealth as champion. Channels are used primarily for marketing and community engagement rather than direct player support, which runs through operator partners.
Greentube's catalogue spans roughly 30 actively marketed titles at any time, drawn from a much larger historical library built around NOVOMATIC's classic franchises and newer progressive families. The studio maintains a steady release cadence, regularly adding titles like Piggy Prizes and Lone Star Link to keep operator lobbies fresh.
Greentube is dual-regulated by the Malta Gaming Authority (MGA/CRP/120/2006) and the UK Gambling Commission, with additional Gibraltar, Alderney and US state licences in New Jersey, Michigan, Pennsylvania and Connecticut. It also holds Romanian, Spanish, Italian, Swiss, German, Belgian and Moroccan regulatory approvals across its footprint.
Operators and partners can reach Greentube through the official contact channels listed on greentube.com, where the company provides business-development and partnership enquiry forms. As a B2B supplier, Greentube does not interact directly with players, who are supported instead through its licensed operator partners.
