Mensa Mind Busters

Book excerpt: This gigantic new puzzle book from Mensa includes more than 500 puzzles, from cunning numerical conundrums and testing word games to logic teasers, enigmatic lateral thinking tests, and abstract visual problems. Because they don't follow any special pattern, you'll never know what fiendish challenge is lying in wait on the next page. Get some practice in puzzle thinking with the easy section, build mental muscles in the medium section, and gain a fighting chance for the really hard part. No special skills or abilities are needed, just a bit of common sense, some basic literacy, the ability to think things through, and the stubborn willpower and determination not to be defeated by a mere puzzle.
