Welcome to the 21st National Cipher Challenge – The Empty Vault
The website is now open for registration and you are welcome to dive right in. There is loads to explore, with lots of information about the competition, how to register and take part, and information about how to start breaking codes and ciphers or to improve your skills.
If you have questions then head over to the forum to post them. All registered participants (and teachers) can do that and there is an active community of cipher challenge alumni and forum moderators (the Elves) who are waiting to help. Harry or Jodie might even reply themselves.
It is great to welcome you to the National Cipher Challenge family for this special edition of the competition. We hope you enjoy it,
