GCHQ is a top secret intelligence agency and security agency which recruits some of the very brightest minds. Over the years, their codebreakers have helped to keep our country safe, from the Bletchley Park breakthroughs of WWII to the modern day threat of cyberattack. So it comes as no surprise that, even in their time off, the staff at GCHQ love a good puzzle.

 

Whether they are recruiting new staff or challenging each other to the toughest Christmas quizzes and treasure hunts imaginable, puzzles are at the heart of what GCHQ does. Now they’re opening up their archives of decades’ worth of codes, puzzles and challenges for everyone to try in the form of The GCHQ Puzzle Book.

Heads Together

The proceeds from sales of the book are being donated to Heads Together, the campaign being spearheaded by the Duke and Duchess of Cambridge and Prince Harry, which aims to change the conversation on mental health from fear and shame to confidence and support.

This campaign wants everyone to feel comfortable talking about their mental health and able to support their friends and families through difficult times.
