Be a Codebreaker £4.95

This book is best thought of as a set of enjoyable puzzles for children of 10/11 and upwards. Breaking codes using letter frequency is an interesting activity which can quickly become very absorbing.

There are clear principles to be followed but also plenty of opportunities for inspired guesses and sudden good ideas. The setting is of ancient maps, mysterious deaths, lost cities and shipwrecks and in each case a successful deciphering leads to where the treasure is buried. If any of the codes proves too difficult to decipher, then help is given.

But in not too helpful a way!
