The National Cipher Challenge

8,000+

Talking of big numbers, this year, for the first time, we have over 8,000 registrations for the competition. After a number of years with around 7,500 this is a big step forward. If you have any ideas what we should do to try to get to 10,000 then let us know! You can email us at [email protected] and we always love to hear from you.
