This is the fourth edition of the Alan Turing Cryptography Competition. We started in 2012, initially the idea was to organise a one-off event in celebration of Alan Turing's centenary that year. However the response we got was so positive and the interest in the competition so much larger than we anticipated that we decided to turn it into a yearly event.

Below you can find a brief overview of the earlier editions of this competition, with links to their websites. These sites are still available, in particular also all previous cryptopuzzles (and their solutions) can be found there! The stories evolve around Mike and Ellie, two schoolkids who find themselves in a new adventure every edition.

2014

This was the third edition of the competition. A top secret section of MI5 is desperately trying to find the 'Lovell Legacy', a machine powerful enough to break any encryption. Allegedly designed by Alan Turing and built at Jodrell Bank under Bernard Lovell, it was buried there and never recovered. Together with their old friend Barquith Mike and Ellie end up in some hairy situations as Lungrem (or is it Mel Gurn?) wants to avoid them interfering at all costs...

The three best teams in the competition were:

1. Hedgehog (Headington School, Oxford)
2. BWBoffins (Bridgewater High School, Warrington)
3. GJMC (St Ninians High School, Glasgow).

2013

This was the second edition of the competition. In the early 20th century, an ancient statue is stolen by a petty criminal with an interest in codes; it's never recovered. Guided, unknowingly, by a former student of Alan Turing, Mike and Ellie seek to find the missing statue. A mysterious machine called the 'Egyptian Enigma' plays a crucial role in a quest that leads them even to visit the Alan Turing Building...

The three best teams in the competition were:

1. G15 (Calday Grange Grammar School, Wirral)
2. Room40 (Torquay Boys' Grammar School, Torquay)
3. SmileyFaces:) (Sir William Borlase Grammar School, Marlow).

2012

This was the first edition of the competition. Mike and Ellie got entangled in a search for the illustrious 'Turing Treasure' which led them on a tour along several famous places in Manchester, having to solve cryptographic puzzles on their way. Also, they were not the only ones on the hunt for this treasure...
