Welcome. This is a site for fans of codes, ciphers and puzzles.

The JCC April Champion is Katie Schilling. Congratulations, Katie.

Can you crack it too? 

April Cipher


To celebrate World Book Week there’s a coding challenge, which of course includes a Book Cipher. 



To crack ciphers with Ben, Jess and Freddie – or even beat them to it – you might like to read my books. 

Have fun,

If you would like a code-cracking course, I often run them in UK primary and secondary schools, as well as writing workshops and Einstein or Darwin assemblies.
