Smashing things is a long-established and highly effective method for stress relief, and Smash Hit elevates it into an art form. Glass walls, windows, pyramids, and even DNA-like helixes are thrust into your path as you fly forward at an accelerating pace, and the only thing you need to do is destroy them before they slam into your face. Simple and addictive to play, gorgeous and delightful to look at.

Hearthstone This one's limited to devices with screens of 6 inches or above for now, though Blizzard has already promised to bring it to Android phones as well. The reason you'd want to dive into the Warcraft universe and play Hearthstone is the same whether on Android, PC, or any other platform: thrilling one-on-one battles that depend on a finely balanced mix of forethought, tactics, and luck. Just be warned that once you start building up your stack of cards, addiction quickly follows.
