Blizzard has officially launched Hearthstone: Heroes of Warcraft on PC and Mac.
"Once you've completed the introductory missions, you'll have access to all of Hearthstone's exciting offerings. Practice against the AI and you'll be on your way toward unlocking all nine of the original World of Warcraft classes: Mage, Priest, Druid, Rogue, Shaman, Hunter, Paladin, Warrior, and Warlock.
"You can also challenge your friends to a duel, test your might against other players in ranked and casual Play mode matches, or fine-tune your mastery of deck construction for fantastic rewards in the Arena. An endless variety of decks are just waiting for you to build and play."
To coincide with the game's launch, Blizzard has released a Hearthstone patch introducing new features, balance changes and bug fixes.
At BlizzCon in November 2013, Blizzard revealed that Hearthstone is in development for iPhone and Android, in addition to PC, Mac and tablet devices.
