Welcome to this home of codes and ciphers and puzzles.
The September JCC Challenge is a Playfair Cipher. Huge congratulations to Katie Schilling, who successfully cracked it and is therefore our JCC Champion on the month. Can you join her?

There are lots of ciphers on this site and in my books.
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.
