Greentube is the NOVOMATIC Digital Gaming and Entertainment division, with roots going back to 1998 and a long connection to classic slot entertainment.Its catalogue includes recognisable names such as Book of Ra™ deluxe, Lucky Lady’s Charm™ deluxe, Sizzling Hot™ deluxe and Reel King™. Free demos make it easy to check the symbols, features, bonus rounds and mobile gameplay before choosing a slot.
Greentube’s official history starts in 1998 with the launch of Ski Challenge under the name Dürrschmid&Reisinger OEG. The company was renamed Greentube Internet Entertainment Solutions AG in 2000 and became part of the NOVOMATIC Group in 2010.
The official Greentube catalogue includes classic online slot names such as Book of Ra™ deluxe, Lucky Lady’s Charm™ deluxe, Sizzling Hot™ deluxe and Reel King™. These games explain why many Greentube releases feel close to traditional slot machines: familiar symbols, direct game titles, simple themes and clear bonus structures.
Greentube’s slot pages also highlight recurring game elements such as free spins, bonus rounds, Wild symbols, Scatter symbols, mobile compatibility and varied themes. The official navigation separates slot families and mechanics including Diamond Link Series, Win Ways™ Mechanics and Diamond Mystery™ Series.
The visible demo count reflects only the Greentube games currently added to this catalogue. It should not be read as the full size of Greentube’s official portfolio.
