Brainiacs on the prowl for challenging fun will find everything they're looking for in these cunning conundrums. Puzzle master Terry Stickels has created a mind-melting collection filled with hundreds of diverse and fiendishly tricky problems--including wordplay, math, analytic reasoning, logic, visual dilemmas, and code breaking. Figure out the next number in a series, find hidden phrases, and determine what a three-dimensional object would look like from two-dimensional drawings.

A little practice, patience, and imagination are all it takes.

Think ordinary conundrums are just too humdrum? Do you finish crossword puzzles in ink and in no time flat? Then get ready for a serious test of your skills, with the ultimate in mental challenges. We've got crosswords of course; more than 50 tough, "regular" ones. But you'll also enjoy dozens and dozens more of different varieties, including devilish "Crushwords" where you have to put more than one letter in each square, and mind-blowing math and logic teasers known as pixel puzzles, where if your answers are correct you'll create a picture of success! And if that isn't enough, you'll also find word puzzles that demand "lateral thinking," and may well be the truest test of your abilities.

A unique compilation of logical teasers and lateral-thinking problems designed to stretch your brainpower and strengthen your mind. Riddles, paradoxes, and conundrums have been confusing and confounding people since at least the time of the Ancient Greeks. The eponymous riddle, according to legend, was devised by Albert Einstein as a child. He claimed that only about 2% of the population would be able to work out the correct answer. There are no tricks and there is only one answer. It requires the cool application of logic to solve. And a lot of patience. Einstein's Riddle features fifty of the toughest logic problems, lateral thinking puzzles, and tests of mental agility. By turns entertaining and infuriating, the puzzles challenge our preconceptions, tell us about how we reason, and provide a rigorous intellectual workout.
