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:   December 2018 

Congratulations to Katie Schilling, who has once again cracked the codes in the monthly challenge first and is therefore the very worthy December JCC Champion. 

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.
