Excerpt: The developers still haven't figured out how to produce a quality assortment of skill-based games. Luck still plays a larger role than it should and sometimes threatens to turn everything upside-down. In one stage, for instance, you have to dig fossils from a field of clay. Since you can't see your buried targets ahead of time, you basically have to tap the screen like a madman and hope for the best.
Excerpt: After you've completed a set of exercises, the game will present a handy little chart that shows where you've proven your skills lie. Both left and right hand are rated, so you can see what difference there really is. For the most part, that's the hook behind the whole game.
