Finish layouts, do tricky calculations, and solve the complex mysteries of visual designs. Take a scissors and try to duplicate a "mind-bending" curved design with just a few snips.

In The Total Brain Workout you’ll find 450 fun, challenging and absorbing puzzles designed to specifically target the core parts of your brain that control language, logic, memory, reasoning and visual perception.

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.
As students unravel 160 fun, easy-to-do puzzles, they review important math concepts, such as money, sums, fractions, and square numbers. The object of each puzzle is to make a line of coins that satisfies the 2-5 clues that are given for each puzzle. The book begins with puzzles for beginners and moves on to more challenging puzzles that have two solutions or superfluous clues. Solutions are provided at the end of the book. Students can use real or plastic coins, create their own money, or simply write the coin values in the given circles.

Marcel Danesi explores the psychology of puzzles and puzzling, with scores of classic examples. His pioneering book is both entertaining and enlightening." --Will Shortz, Crossword Editor, The New York Times "... Puzzle fanatics will enjoy the many riddles, illusions, cryptograms and other mind-benders offered for analysis." --Psychology Today "... a bristlingly clear... always intriguing survey of the history and rationale of puzzles.... A] splendid study...." --Knight Ridder Newspapers
