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.
