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

We have opened the website early this year in partnership with The Mathematics Teacher Training Scholarships and the Institute of Mathematics and its Applications who are sponsoring a special “Teacher Taster” to introduce you to the competition. We are making several changes to the site over the summer, but feel free to take a look around to get a feel for what is involved.

Unlike the autumn competition the IMA taster has single round which will be open from 1st-31st July, and it is open to UK based teachers and trainee teachers. You can find the full terms and conditions on the Challenge page. The taster is independent of the National Cipher Challenge but it does set the scene for the story. If you can’t take part now don’t worry, we will publish the solution to the taster at the start of the full competition so you won’t miss out.

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 special episode of the competition. We hope you enjoy it.
