Worms and Worms Armeggedon. Throw back to the old PC and Sega Dreamcast versions of the games. Games are super fun and addicting. A bit pricey but i can definitely say i got my money's worth and then some. I play on pretty much a daily basis.
Infinity Blade but it's getting a bit too hard for me and after a while it gets monotonous. I am on Dungeon Hunter II right now. Also Cut The Rope.
