Puzzles and Quizzes

Published in association with The Turing Trust, this incredible collection of codebreakers allows you to test your own skills - if you can solve every puzzle in the book you might once have been recruited to join the ranks of Alan Turing's codebreakers! It contains a breath-taking range of different types of puzzles, and so presents a wonderfully entertaining challenge for any puzzle lover. The puzzles are arranged by level of difficulty and become progressively harder, so you can start with the (relatively) easy ones and build up to the truly expert level tests
