We’re taking part in the annual
#GCHQChristmasChallenge on Wednesday 11
December. Students will be set the task of
cracking seven fiendish puzzles and then using
their answers to uncover a hidden message. You
can have a go at home too! The challenge will be
available for anyone to download on the GCHQ
website from 11 December.
This one got all of us thinking today ..
