Hearthstone: Heroes of Warcraft, the free-to-play digital card game, has exited beta and is now available for free to all players, Blizzard Entertainment has announced.

The game is available on Mac and PC with iPad support coming soon.

"We saw some reports early on that Hearthstone might destroy the planet," said Mike Morhaime, CEO and co-founder of Blizzard Entertainment. "We're pleased to see that the game has been released and the planet is still here . . . though we apologise for all the lost productivity."
