Eighty puzzles. The answers are easy! But getting there is the hard part. Uncover connections and identify hidden relationships until suddenly the answers are appearing as if by magic.

Can you imagine the mirror image of a given object, or the best way to connect a series of geometrical shapes? These tricky puzzlers will test your ability to do these things and more . . . and help you develop valuable mental skills. All the answers appear in the back.
Here are enough tough puzzles to test your mental powers for hours and hours. Try this never-ending array of puzzles, challenges, funky facts, things to build, weird riddles, and other conundrums. Some are old favorites that never fail to stump, others are totally new, but all promise hours of fun. Every one can be completed with a pencil, pen, or some inexpensive materials around the house. 96 pages, 105 b/w illus., 5 3/8 x 8 1/4.
Stand out from the pack--don't think conventionally, think laterally! And, you can start developing well-honed mental skills with more than 80 braintwisting puzzles that test your creativity and smarts. At first it might not seem as if there's enough information to solve them, but if you just persist, you'll come up with the logical answers. Some of the conundrums come from real life: try to figure out how the Greek playwright Aeschylus could have been killed by a tortoise or how the truth about Mary Queen of Scots' baldness was finally revealed. Or, give this a shot: A runner was awarded a prize for winning a marathon. But, the judges disqualified him when they saw a picture of his wristwatch. Why? Happy puzzling! Answer: A picture of the runner early in the race showed him wearing his watch on his right wrist. When he crossed the finishing line it was on his left wrist. The judges investigated and found that one man had run the first half and his identical twin brother ran the second half of the race.
What a bargain! At more than 700 puzzle-packed pages, this huge, value-priced collection should keep any solver happy...and busy for a very long time. It contains brain-busting challenges of almost every type: math logic problems for the numerically inclined; absolutely amazing lateral thinking conundrums; really great critical thinking bafflers; and mind-boggling word puzzles. Here's just a small sample of what's inside: The 22nd and 24th presidents of the United States had the same mother and the same father, but were not brothers. How could this be so? Stumped? That's because it's one man--Grover Cleveland--who was reelected after skipping a term. And that's just an easy warm-up!
A man writes the same number, and nothing else, on 20 sheets of paper. Why? To figure this out--and hundreds of other mind-bending lateral puzzles, too--you'll have to really fire up your brain and imagination. At first, it may not seem as if there's enough information to come up with a solution. But look more closely; there's always more than meets the eye. Check your assumptions, ask good questions, retune your mind, separate the facts from the red herrings, and the answers will come.
