Sharpen your mind to beat the smartest brains in Britain with the original official GCHQ puzzle book
Would GCHQ recruit you? Pit your wits against the people who cracked Enigma in the official puzzle book from Britain's top secret intelligence and security organisation
Over the years, their codebreakers have helped keep our country safe, from the Bletchley Park breakthroughs of WWII to the modern-day threat of cyber attack. So it comes as no surprise that, even in their time off, the staff at GCHQ love a good puzzle.
Whether they're 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 this book you will find:
- Tips on how to get into the mindset of a codebreaker
- Puzzles ranging in difficulty from easy to brain-bending
- A competition section where we search for Britain's smartest puzzler
With hundreds of stimulating puzzles, The GCHQ Puzzle Book is the perfect companion and will keep you occupied as you attempt to beat the smartest brains in Britain.
