Blizzard have confirmed that both the Android and iPhone versions of Hearthstone will be cross-compatible with the PC, Mac, iPad and Android tablet versions of the game.

Eric Dodds, one of the designers of Hearthstone, stated in an interview with GameSpot that players will still be given no clues about what device their opponent is playing on.

“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,” he said.

Undoubtedly, Hearthstone is a game that will use up power. Eric did express some uncertainty about how they are going to make the most of the phone’s battery life:

“Hearthstone is certainly… it’s a beautiful game, so it definitely uses power,” Dodds stated. “One thing we’re constantly thinking about is how to make the most of the phone’s battery.”

It may also be a concern for some that Hearthstone has an always-online connection policy, so it could potentially use up a lot of data when being played on a smartphone. Eric expressed that he was unsure how much data Hearthstone would eat up:

“I don’t know if it uses a lot of data,” he said. “You have to have a constant connection though. I wouldn’t recommend playing it on a train.”
