HearthStone is a digital and online cards game in which two heroes from World of Warcraft come face to face to see who is implementing the best strategy to defeat the opponent.
Launched just over two years ago, HearthStone has the largest audience of any online strategy game, drawing more than 7.5 million viewers on Twitch, and with more than 50 million players globally, a number that has been increasing since the release of the game. This has been possible because of its excellent adaptation for mobile devices, ease of play and being free-to-play.
