Some of their early success was in card game adaptation, which is why they were initially recognised as pioneers of online multiplayer games. Their reputation became more solidified in 2005 with the 3D downhill skill game, Ski Challenge, which was premiered in time for the ski season as showcased the company’s Austrian roots.

Novomatic
In 2010, Astra Games, part of the Novomatic group, acquired Greentube. Less than a year later, Novomatic was paying special attention to the newcomer, which showed it had great potential of its own.
Novomatic has been a giant of the land-based gambling sector since the 1980s. Greentube allowed them to expand further into online gambling, and they became Novomatic’s primary launch platform for online slots and table games.
The close Greentube-Novomatic relationship has led to Greentube featuring many Novomatic original titles in its mobile slots catalogue.

Games
Greentube’s huge catalogue is a combination of their own mobile-first releases and Novomatic games adapted for online casinos.
As we mentioned before, some of Greentube’s early hits were multiplayer card games. This is the foundation for their great variety of table games, which includes different styles of baccarat, blackjack, poker, roulette, sic bo, bingo, and much more.
The developer also has some interesting skill games.
Greentube slots
The most important games of Greentube’s catalogue are online slots.
They feature everything from classic fruit machines, like Fruit Magic, The Alchemist and Mermaid, to historical and mythological adventure themes like Apollo God of The Sun, Columbus Deluxe and Attila.
Most importantly, it was Greentube that brought Novomatic’s classic land-based slot Book of Ra to the online world, and produced the now-legendary Book of Ra Deluxe.
Check out our list of Book of Ra clones if the original game isn’t available in your casino or country.
All their slots have different combinations of features, including free spins, scatter symbols, wild symbols and much more!
