“This book, however, focuses almost exclusively on puzzles within recreational mathematics, and surveys a wide variety of them. The book’s title comes from the Ahmes Papyrus (also called the Rhind Papyrus), that contains some of the oldest known puzzles. One of the peculiarities of the problem-puzzle distinction is that is it time-dependent, because we develop new standard methods from working on particular puzzles.” (Allen Stenger, MAA Reviews, January, 25, 2019)​
