IQ Challenge: Over 500 New Mind-Bending Puzzles

by Joe Cameron

More than 500 conundrums, mind-benders, and mathematical teasers will help puzzle fans push their IQ levels to the maximum. Visualize this collection as a ladder into the stratosphere of intelligence: 20 levels of ascending difficulty each contain a variety of numerical and alphabetical questions that tease and stimulate the brain. Start from the beginning, with Level One, and work methodically through to the end. Think logically, rationally, and laterally when unraveling these tangled mental knots, and watch for emerging patterns that make solving the later problems easier. Resist the temptation to look at the answers (all at the end), and when you're stumped, try to look at the puzzle from a different perspective--that's how to sharpen the wits and train the mind.

Customer Reviews

Starts out challenging, becomes 22 times more so!

The book trains your brain to think logically. The same puzzles appear to show up in each chapter, but there is a new twist every time. And logic you've learned to apply to one type of puzzle can suddenly solve something completely different. You are encouraged not to look at the solutions when you are stuck, but rather to return to that puzzle later and look at it from a different point of view. Can you follow that rule? Sometimes I just have to peek at the answer! These puzzles are fun, and some are truly amazing!

Love this book!
