Click here to see a review of the book, along with some Hex puzzles set by Oliver Roeder of FiveThirtyEight. . . . this is not a mathematics textbook, and people who are not terribly interested in mathematical proofs and reasoning will still find much of interest here. In addition to discussing some of the mathematics behind the game, for example, the book also addresses at great length the history of Hex[. . .]. In addition to tracing the history of Hex, the authors also include lots of actual puzzles, with solutions, and discuss at length aspects of Hex strategy. Games that are related to Hex, such as Bridg-It and Rex (also known as reverse Hex ), are also discussed. [. . .] Because of its mathematical content, instructors of courses in subjects like game theory or discrete mathematics might want to flip through it as a potential source of lecture material. People interested in the history of mathematics might find some of the biographical and historical detail here interesting. And of course anybody who enjoys the game of Hex will find much of here interest as well. It's a fun book. -Mark Hunacek, MAA Reviews
