Everyone who is fascinated by logic, spatial-visual and/or math puzzles knows Terry Stickles' name. His puzzles have tantalized and often stumped not only super-adept puzzle mavens, but the rest of us. He has published books, puzzles, articles about puzzling, and sets of puzzle cards -- all eagerly snapped up by those thousands who can't get enough of brainteasers. His puzzles have appeared on National Public Radio's puzzle program, in Discover and Games Magazines, and he was asked to provide challenges for the recent World Puzzle Convention. But one trait in particular sets Stickles' teasers above so many others: every one is original. Stickles agrees that recycling is a public duty, but not, he says, when it comes to puzzles. So whether one starts at the beginning section of So You Think You're Smart, Huh? where the author is kind enough to launch us with more gentle challenges (but still challenges, and don't forget it!) or the latter section, where he gets really tough, the reader will find wonderful fun, refreshing brain workouts, and the deep satisfaction of matching wits with the country's most prominent puzzlemaker --and coming out ahead. Sometimes.
