STP: In an App Store stuffed to the brim with clones and tired ideas, a game like Triple Town is a rare treat. Like chess, it’s a strategy game with a set of simple rules that govern the actions of a variety of pieces. Also like chess, the deeper you dig, the more complexity you unearth. To top it off, the game is mega-addictive, and it's free to play. Not bad for a game full of cartoon bears.
