Posted — 01.12.2018

Have a go and be in with a chance to win a cool GCHQ puzzle book or Red Team Field Manual. How does that sound for a stocking filler?

How to enter:

1. Visit www.cybergamesuk.com/xmas

2. See if you can enter all of the answers correctly

3. If you get all the answers right, you’ll be given a secret passphrase

4. Send a private message on Twitter to @cyberchallenge with the secret passphrase exactly as it appears. Remember not to share the secret passphrase publicly!

5. Tweet something like this to let everyone know you’ve played, “I played and completed the @cyberchallenge Christmas cipher game!”

Entries submitted after the closing date of 18 December 2018 will not be counted.

Good luck and Merry Christmas!
