A compendium of the cleverest, toughest, strangest, wildest, prettiest, most elegant and deviant exercises of mental gymnastics around, this bestselling book is a must for anyone who likes puzzles that actually pose a challenge. Mixing off the wall humor with on-the-ball logical puzzles, here is a thousand hours of brainteasers and word twisters in one giant book. From Think-and-Blink to Eyeball Benders, from Dszquphsbnt! to Sequences, each page is a winner for both aces and amateurs. A special 32-page section in full color presents artistically pleasing and logically enigmatic labyrinthine dilemmas. (Try dodging the hidden cameras in the three-dimensional maze.) Answers are revealed in the back of the book. Selection of the Literary Guild. 356,000 copies in print.
