It is the dawn of a new age of global connectedness. Airship routes have made the world smaller, reducing voyages of many months to flights of only a few days. However, the dangers of long-distance travel remain – especially the danger of pirates. Bands of fearless opportunists resembling the pirates of old have taken to the skies in their own airships, terrorising and plundering passenger and cargo vessels alike – or so the stories go.

But you never thought you would encounter any actual airship pirates. Until it happened on your first transatlantic flight. Worse yet, this crew of pirates appear to have a strong interest in a certain document in your possession and need you to translate it. Only thing is, you don't know how. You'll need to stall for time and gain their confidence in order to avoid being made to walk the plank. And who knows: solve the challenges that come your way, and you may end up with a share of the treasure...

How to participate

There are eleven challenges in total, ranging from simple logic problems to complex technical puzzles. Solving each challenge will give you a passphrase, in the format hackfu[a-z]+, which can be used to decrypt the solution.txt.enc file for that challenge. In addition to the second part of the story, this file will give you a challenge codename, a unique UPPERCASE THREE-WORD PHRASE, which can then be submitted along with the email address you used to register and a detailed description of how you solved the challenge (very important!). Each submission will improve your standing on the leaderboard, and increase your chance to win!

The challenge will run from 23 April 2018 to 23 July 2018. Submissions will close just before midnight Baker Island Time.
