In Pictures: The 16 best iPhone/iPad games of 2013...
Ratings: 86 from Metacritic; 4.5 stars from App Store users
This original PC game came to iOS and Android earlier this year, providing a physics puzzler backed by soothing music as you tilt or touch a crystal ball from silhouetted scene to silhouetted scene. (You’re going to rub the skin off your index finger if you play this for too long at one-sitting, not that I would have done that.)
