Game of Thrones Ascent has arrived on iOS and Android devices, developer Distributor Beam has confirmed.
Originally released online in 2013, the social game based on the popular HBO show is now available in the App Store and Google Play.
"While we have more than 4 million players across the existing web and iPad versions of Game of Thrones Ascent, we know there are still many people who prefer to play games on their iPhone or Android phones and tablets," said Distributor Beam CEO Jon Radoff.
"We're thrilled to now extend the game to an even wider audience! We've re-designed the user interface so that players can now enjoy the same great gameplay that they've seen online, but on these new devices."
The game encourages users to take part in multiple story-driven quests, where they can develop their own lands and reputation among the Great Houses.
Players can also choose their path to success via Battle, Intrigue or trade.
Throughout the remainder of this year, Game of Thrones Ascent will be updated on a weekly basis.
An episodic Game of Thrones video game is also scheduled to launch this year.
