Blizzard finally brings its combat strategy game, Hearthstone: Heroes of Warcraft, to even smaller screens. It's now available on iOS Universal so it'll work on your iPhone as well as on Android tablets and phones. The smartphone version gets a redesigned interface to make it easier to play on the smaller displays. Since there are a lot of cards on the board at any given time, what Blizzard did for the phone is you can only see half of the cards at a time, and you can just tap on them to see zoomed-in version of the cards. 

The great thing is you can play the full game right from your mobile device. It even supports Naxxramas and Blackrock Mountain expansions. But these are sold separately. And it also syncs with your account on Blizzard's Battle.net system, so no matter where you play, it'll count towards your stats. However, this means you have to be online to play the game even if it's just against the AI.
