On Thursday, Loyola Academy students took part in the annual #GCHQChristmasChallenge.
Students were set the task of cracking seven fiendish puzzles and using the answers to help uncover a hidden festive message!
Students had to work together in teams and utilise their different strengths to solve the puzzles.
Congratulations to students in years 8, 9 and 11 who fully completed the challenge and solved the final code.
You can have a go at home too; the challenge is available for anyone to download on the GCHQ website now.
