Amusements in Mathematics

All 430 puzzles from Henry Ernest Dudeney's 1917 classic, from money and clock puzzles to dissections, unicursal routes, chessboard tours, magic squares and mazes, each retold in modern words and answered in full.

Amusements in Mathematics is Dudeney’s largest book: twenty-odd chapters of arithmetical, geometrical and combinatorial puzzles, many of them still quoted a century later. This edition restates each puzzle clearly, keeps the old money and measures where the puzzle depends on them, and works every answer through, so that the reader sees not only the number but why it is the only one.
