The GCHQ Puzzle Book

Perfect for anyone who likes a good headscratcher

  • GCHQ


A unique book of puzzles from British intelligence organisation GCHQ

GCHQ is a top-secret intelligence and security agency which recruits some of the very brightest minds. Over the years, their codebreakers have helped 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'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.

Praise for The GCHQ Puzzle Book

A fiendish work, as frustrating, divisive and annoying as it is deeply fulfilling: the true spirit of Christmas

Guardian

Surely the trickiest puzzle book in years. Crack these fiendish problems and Trivial Pursuit should be a doddle

Daily Telegraph

Ideal for the crossword enthusiast

Daily Telegraph

An explosion of a puzzle collection, too, with hundreds of questions and loads of peripheral material, including captioned photographs and history of twentieth-century British encryption, featuring the work of Alan Turing

The Times Literary Supplement

WINNER OF STOCKING FILLER OF THE YEAR AWARD

THE GUARDIAN

This isn't your grandfather's Sudoku book. Rather, it's a puzzle compendium put together by the organisation that made the Bletchley Park breakthroughs - quizzes, bewilderments and brainteasers to challenge even the sharpest of minds
