This game is crazy fun. Take a look at the GiantBomb quick look... if you aren't sold after watching that video, you must hate fun! Even though the game is suggested for tablets or large phones, I've had almost no issues playing on my Nexus 4.
Pixel Defenders Puzzle
Excellent Match-3 game with a few tactical RPG-like twists. This game has no ads, no IAPs, and no intrusive permissions. The developer has also hinted at Google Play Games support in the future.
