Train Your Brain Cranium Crunchers

Hey kids--are you ready to train your brains? This series of fun books will really let kids give their brains a workout! Designed by a puzzle-book pro and the creator of the online brain-training site Brained Up (www.brainedup.com), these brain-teasing books are brimming with mind-scrambling puzzles that have been scrutinized and approved by British Mensa. In Cranium Crunchers, there's almost 100 pages of number stumpers, visual teasers, logic problems, and verbal tests. Split into three levels of difficulty--called Super Brain, Mega Mind, and Ultra Genius--the books get more challenging as they progress. Kids, adults, and anyone else who enjoys a good dose of mental calisthenics will find themselves hooked by each puzzle-solving challenge.
