Six students took part in this National Cipher Challenge, run yearly by the University of Southampton, and the group solved the 10 ciphers on a weekly basis. Points are scored for how quickly they are de-ciphered, and the team (Code crackers and cheese) finished joint first in Challenge A and B along with several 100 other teams. Amazing work!

This image is just a sample, but the idea is to try to get the alphabet from these digits, then put them in the right order so that it reads a message.
