It may not be worldwide yet, but the Hearthstone rollout on iPad has officially begun. The free-to-play game is currently available on iPad in Canada, New Zealand, and Australia and according to a press release from Blizzard, "Pretty soon it'll be available everywhere."
The statement says that Hearthstone's player base has currently grown to "10 million registered accounts." But for anyone holding out for a non-iPad or PC version, "Android device, iPhone, and Windows tablet versions are also in development and will be available in the future."
Downloading and playing the game on iPad will also net users a free card pack whether you win or lose.
Savvy players who aren't yet in the rollout countries may find ways of accessing the game early, but then again, patience is a virtue. The game officially left beta earlier this year, though it does require an Internet connection to play, regardless of what device you play it on.
