The first book to present combinatorial game theory in the form of a textbook suitable for students at the advanced undergraduate level ... The authors state and prove theorems in a rigorous fashion [and] the presentation is enlivened with many concrete examples ... an outstanding textbook ... It will also be of interest to more advanced readers who want an introduction to combinatorial game theory.
