The Raven's Hat: Fallen Pictures, Rising Sequences, and Other Mathematical Games

Games that show how mathematics can solve the apparently unsolvable.

This book presents a series of engaging games that seem unsolvable—but can be solved when they are translated into mathematical terms. How can players find their ID cards when the cards are distributed randomly among twenty boxes? By applying the theory of permutations. How can a player guess the color of her own hat when she can only see other players' hats? Hamming codes, which are used in communication technologies. Like...
