The national espionage agency has given a mysterious Christmas challenge this year, with hints including American soldiers, Indian butter, and Latin dancing.
Director Anne Keast-Butler sends out a Christmas card as GCHQ’s yearly brainteaser.
The audience is challenged to decrypt the names of UK sites in this year’s puzzle, which tests their numeracy, lateral thinking, and codebreaking abilities.
GCHQ stated that persistence and inventiveness are necessary for the surprisingly difficult tasks.
For those who wish to push themselves even more, the 2024 card has extra layers with more components concealed in the coding.
“Colin,” the top puzzler at GCHQ, called this year’s tests “fiendishly enjoyable.”
