This is a delightful book. Marcus has a love of games and this comes across in the book, this is very much a personal journey. There is a little bit of mathematics but it is not intrusive, it is background and adds to the story.
The games are from around the world and are games that originated in a particular area or country. The games are described from a personal point of view and describe Marcus' relation with game. I particularly liked the Dungeon and Dragons chapter.
If you enjoy puzzles or games you will love this book.
