00:00 Hello, I'm Colin, the Chief Puzzler at GCHQ. Welcome to the 2023 GCHQ Christmas Challenge.
00:08 This year, we've set you seven different puzzles which call upon a variety of different
00:12 skills and disciplines which we use every day in our work to help protect the UK. Each
00:18 question has a one-word answer which can follow the word 'Christmas'.
00:23 Once you've solved the seven brain teasers, you'll need to use the design on the front
00:26 of the card to place certain letters from your answers in the grid at the bottom of
00:30 the card. When you do so, you'll reveal the final answer and a special Christmas message.
00:36 Don't worry if you get stuck. After all, the puzzles have been put together by some
00:40 of our finest minds. Teamwork is key here. Bringing together a mix of minds will give
00:45 you the best chance of completing the challenge. Make sure to get involved on social media
00:49 using the hashtag #GCHQChristmasChallenge. Let us know how you're getting on, and if
00:55 you need any help, I'll be on hand to provide hints and tips throughout the day. Good luck!
