Cranium-Training Logic Puzzles

Get your brain in shape with more than 300 logic puzzles! Mike Rios has devised a fun collection with 12 different types of cranium trainers, starting with easier ones and getting harder as you build your skills. Some - like nurikabe, dominoes, corral, and yajilin - are familiar to fans of the genre, while others are brand new. So sharpen your pencil, and your mind, and see how well you do.
