Hearthstone has reached the 30-million player mark, Blizzard Entertainment has announced. The popular free-to-play collectible card game is available on PC, Mac and mobile devices, including iPad, iPhone, Android phones and tablets. The company didn’t specify how many of those 30-million players are still active, but its growth is impressive considering Hearthstone reached 20-million players in September 2014.
The game was originally revealed in March 2013 and was officially launched a year later. Most recently, Blizzard added support to mobile phones and a new expansion, Blackrock Mountain, which added 31 new cards to the game. The Blackrock Mountain adventure follows up on the Goblins vs. Gnomes expansion that was released in December 2014 that added over 100 cards.
