The Cryptoclub also includes short descriptions of famous examples of secret codes, including the Beale Ciphers, the Zimmerman telegram, and the German Enigma cipher. The Cryptoclub is intended for middle-school students, and could be used for classroom teaching or as a supplemental or recreational book for students interested in cryptography. However, the potential appeal is much broader: the simplest ciphers could be solved by a child in grade school, and much of The Cryptoclub can be enjoyed by adults as well.

The Cryptoclub is more than just a math book: a story line is woven around each type of code, making it more interesting for students. This book could serve as a resource for enrichment or gifted programs could easily be incorporated into a cross-curricular thematic unit. Judith Casey, NCTM, August 2007.
