Last year, GCHQ set a challenge to the public in the form of a cryptic Christmas card.

This year, they went one step further and wrote a whole book full of puzzles. The answers to most of these puzzles are in the book, but there are one or two challenges that they haven’t revealed the solutions to…yet.

Penguin Random House and GCHQ went on a hunt for Britain’s smartest puzzler, and this quest began with The GCHQ Puzzle Book, in which the first part of The GCHQ Puzzle Book Competition appeared.

Like last year’s competition, this one had various parts to it, and these required both puzzle-solving and codebreaking skills. As you proceeded, the instructions for entering the competition became clear.

THE COMPETITION CLOSED ON 28TH FEBRUARY 2017 AND A TIE-BREAKER WAS ISSUED TO THE FINALISTS.

 

The GCHQ Puzzle Book Competition – Results!

The winner of the GCHQ Puzzle Book competition was Angus Walker. Congratulations, Angus!

Many congratulations also to the runners up, who made it through to the tie-breaker round:

  • Jessie Wheat
  • Alfie Baines
  • Selim Barhli
  • George Attwood
  • Catherine Baines

Special mention should also go to Wim Hulpia for scoring very highly in the competition. Wim was one of the joint winners of the puzzle set by GCHQ at Christmas in 2015. Congratulations from the teams at GCHQ and at Penguin Random House.

 

Even though the competition has now closed you can still get yourself a copy of The GCHQ Puzzle Book and test your wits against the nation’s best codebreakers!
