Three people have been declared winners of GCHQ’s Christmas puzzle challenge.
More than 600,000 people tried to solve the puzzle series, with 30,000 making it to the final round of the challenge.
David MacBryan, 41, from Edinburgh, US-born Kelley Kirklin, 54, from London, and Wim Hulpia, 40, from Lovendegem in Belgium, came closest to completing the series of puzzles.
They win a GCHQ paperweight, a pen and a signed copy of Alan Turing Decoded, by Turing’s nephew Dermot Turing.
Mr MacBryan, who is originally from Dublin and describes himself as a professional quiz master, told the BBC: “The more puzzles you do, the better you get at doing puzzles – and I have done a lot of puzzles. I am a bit of an addict.”
The first stage of the puzzle series appeared on the Christmas card sent out by GCHQ director Robert Hannigan.
Filling in squares produced a Quick Response, or QR code, which when scanned took people to a website with the subsequent stages.
