Do you like breaking codes and solving ciphers?
Can you, and your friends, discover the secret of the Carbon Conundrum?
Would you like the chance to use your mathematical skills to win some great prizes?

Then the Alan Turing Cryptography Competition is for you!

Now in its fourth year, the Alan Turing Cryptography Competition is aimed at secondary school children up to Year 11 (England and Wales), S4 (Scotland), Year 12 (Northern Ireland). 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!

Registration for the fourth edition of the Competition will open December 1st. In the meantime, why not explore the previous editions of the Competition to get inspired? You can find them here: 2012, 2013 and 2014.
