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 chequered 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.
