Publisher's Synopsis
Created by Ivan Moscovich, PLAYTHINKS is the first and only book where science, math, and art puzzles all come together. Broken down by chapter, PLAYTHINKS challenges with 12 basic categories, including games of Geometry; Patterns; Numbers; Logic and Probability; and Perception. A special Bonus Round is included for die-hard puzzlers who, after all that, still haven't had enough. An easy-to-read key at the!top of each game ranks its difficulty on a scale of 1 to 10. The lie-flat spiral binding makes the hefty book completely reader-friendly. So do the answers in the back.
