Blizzard is a game developer and publisher - maybe you've heard of them. They're responsible for little series like Diablo, Starcraft, and World Of Warcraft, among others. The company's latest effort is an online, multiplayer trading card game called Hearthstone, currently in an invite-only beta on PC. Polygon reports that at the annual BlizzCon in Anaheim, California, the company announced that Hearthstone will be released on Android in 2014.
Hearthstone is loosely set in Blizzard's Warcraft franchise, hence the subtitle "Heroes of Warcraft." Like other collectible card games, it's being built from the ground up on the free-to-play model, though reports from early beta players indicate that it's still easy enough to get into the main game without spending money.
