Welcome to this home of codes and ciphers and puzzles.
My third book is just out, with lots of codes to crack.
And every month at least there’s a new challenge here.
Fancy another challenge? Click here: Codes
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.
