Here 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.


This was the ninth edition of the competition.

This was the eighth edition of the competition. Who, or what, is behind the series of accidents that incapacitates three top data scientists at the social media company TimeSucker? What role is played by the data-processing supercomputer Cid? Mike and Ellie face a race against time to solve the codes!

Site: 2019 edition


This was the seventh edition of the competition. Who, or what, is behind the death of Professor Garamond - head of a mathematical research institute located in the middle of a foggy moor? Are the rumours of a ghostly hound true? What role do the mysterious Maliphant sisters play? Mike and Ellie must race against time to solve a series of cryptic codes.

This was the sixth edition of the competition. Mike and Ellie get caught up in a race against time to locate the 'Mediaeval Manuscript', a document hidden somewhere within the depths of the John Rylands Library that points towards a centuries-old piece of mathematical knowledge. Should they trust the mysterious monk-like figure of Brother Aldred as they race against against time?

But Professors Kenneth Parry and Alice Loebner - two of the senior scientists - seem to be determined to thwart the development of Geshtu, EKA-labs' supercomputer designed to pass the Turing Test. All is not as it seems, however, and Mike and Ellie must race against time and get deep inside the workings of Geshtu to unmask the conspiracy.
