Sam Loyd's puzzles provided the inspiration for this book. Dipping back into the old master's collection, the Adlers decided to create new drawings, re-style the language and add man new puzzles of their own. The result is a brand new compendium of mathematical, word and geographical puzzles, rebuses and riddles, topped off by all the answers, carefully tucked away at the end. The book is ideally suited for this age level.
