IQ Challenge: More Than 500 Visual, Verbal and Numerical Puzzles to Help Improve Your IQ

by Deborah Hercun

IQ Challenge is divided into 20 sections of equal length, ranging from simple games and conundrums at the beginning, to fiendishly difficult logic puzzles toward the end of the book. Various puzzle types are repeated at intervals throughout the book so that you learn to solve them more speedily as you get used to the different ways to approach the problems. All the puzzles are solvable with practice and a little persistence. If you encounter problems, or if you want to check how well you are doing, all of the answers are provided at the back of the book. (D.H)
