Blizzard's wildly popular digital card game, Hearthstone: Heroes of Warcraft is now also available on Android tablets.

Players in Australia, New Zealand and Canada are the first in the world to get access to Hearthstone for Android tablets, and can now download the game for free on Google Play. Other territories will be able to download the game on Anrdoid tablets in the weeks ahead.

Last week, Blizzard released Goblins vs Gnomes, the first full expansion to Hearthstone, on all platforms. It dives into the deep engineering rivalry between the two races, and adds a new minion type called mechs.

Goblins vs Gnomes adds more than 120 new cards to Hearthstone. The cards can be purchased as packs, crafted with dust, or earned in the Arena.

More than 20 million people have played Hearthstone on all platforms.

Hearthstone is also available on PC, Mac, and iPad.
