Today we unveil the 2023 GCHQ Christmas Challenge. The Challenge is presented in the form of a Christmas card, sent by our Director, Anne Keast-Butler, to partners around the world.
Whilst the Challenge has been designed for schools and colleges, we're encouraging the wider public to take on the challenge to pit their wits against our puzzlers
The year’s Challenge (available to download below) features seven complex puzzles, masterminded by our in-house puzzlers. They are designed to test a range of problem-solving skills and encourage the use of teamwork to reveal the final festive message.
The card design includes a nod to our wartime home at Bletchley Park with a rare image of the snow-covered mansion. It was taken in January 1940, before a photography ban was introduced there, and was discovered in the personal family album of codebreaker Joan Wingfield.Director GCHQ Anne Keast-Butler, said:
Puzzles have been at the heart of GCHQ from the start. These skills represent our historic roots in cryptography and encryption and continue to be important to our modern-day mission to keep the country safe.
GCHQ’s history at Bletchley Park is represented in this year's Christmas card as a reminder of the role this historic place has played in our wartime efforts but also as home to this year’s AI Safety Summit.
Our puzzlers have created a Challenge which is designed for a mix of minds to solve. Whether you are an analyst, an engineer or a creative, there is a puzzle for everyone. This is one for classmates, family and friends to try to solve together.
