Blizzard's free-to-play collectible card game Hearthstone has left beta and launched proper on PC and Mac.
iPad support is coming soon, Blizzard said. Versions for Android, iPhone and Windows tablets are in development and will be available "in the future".
"We saw some reports early on that Hearthstone might destroy the planet," said Blizzard boss Mike Morhaime.
"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."
To coincide with the launch Blizzard has issued a new patch for Hearthstone that tweaks a number of cards, Ranked Play and squashes bugs. Check out the patch notes over at Battle.net.
Meanwhile, the Hearthsteed mount reward can now be obtained for your World of Warcraft account. To get this, win three games of Hearthstone in Play or Arena mode.
