Are You As Smart AsYou Think? contains a hundred and fifty freshly-minted.word, number and graphic puzzles. Solving them takes logic, common sense, and an open mind. Higher mathematics is not required. There's something here for everyone of almost every degree of puzzle-solving skill.

"If you are like me and want fresh puzzles, and not rehashes of old classics, then buy this book. I promise that you will be delighted and entertained." (Michael, Michalko, author of Thinkertoys, ThinkPak and Cracking Creativity.)
