The Alan Turing Cryptography Competition

Do you like breaking codes and solving ciphers? Then the Alan Turing Cryptography Competition is for you! Now in its tenth year, the Alan Turing Cryptography Competition is aimed at secondary school children in the UK up to S4 (Scotland). You don't need to be a computer whizz or a mathematical genius — you just need to keep your wits about you and be good at solving problems!
