Here is a challenge that puzzle fans will find simply irresistible: a really smart, varied, and original collection of more than 200 contemporary brainteasers. Some are visual, others geometric, and still more are topological. They play games with words and numbers, and with matchsticks and coins. And many of them are of World Puzzle Championship level; in other words, really hard. Divide figures into their congruent parts, or rearrange the pieces of a patterned star so that the result precisely matches a checkered cross. Try a little puzzling origami: fold an origami square exactly six times to create the shape of a house. Do cubical inversions, shift coins around from shape to shape in a given number of moves, and much more.
