About the original "1000 PlayThinks," Will Shortz of "The New York Times" said it best: The most wide-ranging, visually appealing, entertaining, gigantic collection of brainteasers since Sam Loyd s "Cyclopedia of Puzzles" almost a century ago. Inside "The Big Book of Brain Games," you will find an obsessive collection of 1,000 challenges, puzzles, riddles, illusions originals as well as must-do classics it s like salted peanuts for the brain. With jampacked pages and a full-color illustration for each entry, the book, opened anywhere, is a call to action. (And it s guaranteed to make you smarter.) Twelve basic categories include Geometry, Patterns, Numbers, Logic and Probability, and Perception. An easy-to-read key at the top of each game ranks its difficulty on a scale of 1 to 10, while indices in the back cross-reference the puzzles. (You ll find the answers back there, too.)"
