Schoolchildren across the country will put their puzzle-solving skills to the test after the UK’s spy agency launched its annual Christmas Challenge.
GCHQ has sent its Christmas card with the challenge, fronted by a rare image of a snow-covered Bletchley Park, to more than 1,000 secondary schools.
It includes seven increasingly complex puzzles that test skills such as codebreaking, maths and analysis, and encourages pupils to work as a team to reveal the final festive message.
A maths-based bonus puzzle has also been included, which has been described as the toughest to date.
GCHQ director 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.

Bletchley Park was the wartime home of GCHQ and the featured image, taken in January 1940, was discovered in the personal family album of Joan Wingfield, who worked on breaking Italian naval codes.
Now in its third year, the challenge aims to provide an insight into GCHQ’s work and inspire young people to study Stem subjects.
