Welcome to this site of codes and puzzles. Every month (at least) there’s a new challenge here.

Here’s the first of 2019:   January 2019

Congratulations once again to Katie Schilling, who has cracked the codes in the monthly challenge first in so many months, and is therefore the very worthy January 2019 JCC Champion.

She has also cracked many of the codes in my books before reading how Ben, Jess and Freddie did so, feeling she is cracking the codes alongside them, she said, writing to me about The Quantum Code.

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.
