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.

Here’s the latest:   November 2018 

Fancy another challenge? Click here:   Codes

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.
