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.


Greentube is licensed to operate in the United Kingdom, Malta, Mauritius, Alderney and British Columbia. The licensing bodies for all these territories subject their games to rigorous independent testing to ensure the fairness of their random number generators (RNGs).

  • United Kingdom Gambling Commission (UKGC)
  • Alderney Gambling Control Commission (AGCC)
  • Malta Gaming Authority (MGA)
  • Mauritius Gambling Regulatory Authority (MGA)
  • British Columbia Lottery Corporation (BCLC)

These companies also audit online casino sites to make sure their business practices are safe and transparent.


A further guarantee of Greentube’s reputation is the number of awards they have won for a broad range of categories. These include their technological innovation, the quality of their games, the services they provide to casinos and, most important of all, their transparency and security.

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!
