Welcome to the 21st National Cipher Challenge – The Empty Vault

We opened the website early this year in partnership with The Mathematics Teacher Training Scholarships and the Institute of Mathematics and its Applications who sponsored a special “Teacher Taster” to introduce you to the competition. That taster is now finished and we have been closed while we got ready for the Autumn competition. Now here it is and we very much hope you will enjoy it.

If you have questions then head over to the forum to post them. All registered participants 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 year’s edition of the competition. Have fun!
