Publisher's Synopsis
Logic is not enough! To unravel a lateral puzzle, you have to train your brain to think differently. Ranging from (relatively) easy to fiendishly hard, these classic conundrums-almost 100 of them-require mental agility. Can you figure out these problems from only the vaguest details and yes-or-no questions? It's challenging, imaginative fun.
