Blizzard has updated Hearthstone for Android and iOS to support smartphones, so you can indulge in its Warcraft-themed free-to-play card gaming while you're stuck in your cubicle. You shouldn't lose any content in the translation, but there's an "all-new" interface designed for smaller screens. Just be sure to exercise some restraint -- it could be tempting to squeeze in one more round before that big meeting.
