Hearthstone: Heroes of Warcraft Released

Free-to-play strategy card game from the creators of Warcraft
Blizzard Entertainment today announced that Hearthstone: Heroes of Warcraft is now available on Mac and PC, with iPad support coming soon. Android device, iPhone, and Windows tablet versions are in development and will be available in the future.
In Hearthstone, players build card decks centered around one of nine iconic Warcraft character classes and duel each other for fun, glory, and the chance to win new cards. In addition to honing their skills in practice matches against the computer and taking on their buddies via their Battle.net friends list, players can challenge each other in two competitive game modes. Play Mode features traditional head-to-head battles, with players facing off for a chance to increase their medal ranking and earn card packs along the way.
And for a different type of challenge, players can enter The Arena, where they start each match by building a deck from a new set of cards, and then use that deck to duel other Forge participants. Aside from winning new cards, players will be able to round out their collections by purchasing new card packs or disenchanting some of their existing cards to craft the ones they're missing.
