The upcoming iPhone and Android phone versions of Hearthstone will be compatible with its PC, Mac, iPad and Android tablet counterpart, Blizzard has confirmed.
"It will be your exact same account, so all your cards on tablet or PC will be available on your phone too," said Hearthstone lead designer Eric Dodds in an interview with Gamespot. "When you start a match on a phone, you could be playing someone on another phone, someone on a tablet, on a PC, who knows? It's all one big ecosystem."
One concern with playing Hearthsone on the go is how quickly it will drain a smartphone's battery due to its always online requirement. "One thing we're constantly thinking about is how to make the most of the phone's battery," Dodds said. "I don't know if it uses a lot of data. You have to have a constant connection though. I wouldn't recommend playing it on a train."
Hearthstone's smartphone versions are due later this year.
