A couple of years ago, I blogged about H. E. Dudeney’s Amusements in Mathematics. Today, I noticed that Project Gutenberg had released a copy of The Canterbury Puzzles by Henry Ernest Dudeney – Project Gutenberg. This book has quite a few more nominally mathematical puzzles than its sibling. In particular, it introduces the game Kayles, which makes appearances in most of the books I have on combinatorial game theory such as Conway’s On Numbers and Games.

Addendum: Some information on strategy for Kayles can be found here.
