Good Brain Exercise
Fun puzzle game that gives your brain a a nice little workout. Some puzzles are easy, some are pretty hard, but most seem to fall right in the middle. Only real complaint is that some of the puzzles extend off the screen and dragging the screen up and down or back and forth is kind of annoying. Solid game/app overall.
