"This isn't your standard book of logic puzzles. Not only will it teach you to master and enjoy some of the more traditional styles of logic puzzles, it also provides a seamless onramp to the more open-ended 'cryptic' puzzles that you'd find in the increasingly popular world of puzzle hunts, such as those found in Puzzled Pint or DASH. --Rich Bragg, founder of ClueKeeper, a platform for creating and playing puzzle hunts

"Steven Clontz's delightful collection of 130 original puzzles is addictive. I knew in advance that I would love the Calcudoku (aka KenKen) puzzles, which come in various sizes. They are great at challenging our logical reasoning skills and our ability to do elementary arithmetic. But I didn't anticipate falling for Masyu and Nonograms. The LogicGrid puzzles brought back fond memories of my childhood. The Cryptic puzzles are indeed baffling. Overall, this collection is sure to tease and please." --Harold Reiter, Professor of Mathematics, UNC Charlotte
