GCHQ is a topsecret intelligence and security agency which recruits some of the very brightest minds. Over the years, their codebreakers have helped keep England safe, from the Bletchley Park breakthroughs of WWII to the modernday threat of cyberattack. So it comes as no surprise that, even in their time off, the staff at GCHQ love a good puzzle. Whether theyre 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 theyre opening up their archives of decades worth of codes, puzzles and challenges for everyone to try. In this book you will find tips on how to get into the mindset of a codebreaker, and puzzles ranging in difficulty from easy to brainbending.

I bought this GCHQ puzzle book as a present for my sister, who loves enigmas and brain teasers. She was thrilled and has been working through the puzzles nonstop. Totally worth it for anyone who loves a good challenge!

Fun But Not My Style
I thought I'd enjoy this puzzle book more, but I struggled to get into it. The puzzles are clever for sure, but they weren't really my cup of tea. Not bad, just not what I expected!

Mixed Feelings About the Puzzles
The idea of this GCHQ puzzle book is fantastic, but I found some puzzles overly complicated. I enjoy a challenge, but a few felt more frustrating than fun. Still, it's neat to see puzzles from the perspective of codebreakers!

This GCHQ puzzle book really makes you think! I love the variety of puzzles, and it's interesting to pit my wits against those who cracked the Enigma. Perfect for long evenings at home or when I need a break from screens.

Great for Brain Exercise
I got this puzzle book as a gift for my dad, who's a huge fan of brain teasers. He enjoys the challenges, but sometimes the clues are a bit tricky to follow. Nonetheless, it's a solid choice for puzzle lovers!
