Inferno Related Kobo Competition

Ebook company Kobo are running a competition related to Inferno title 'The Descent". I haven't had much time to check it out myself, but for those of you who like solving puzzles, $5000 is up for grabs. More details:

The company I work for - Kobo - has launched a game themed on Dante's Inferno leading up to the Inferno release.

We've commissioned eBooks with various imagery, mythology and historical references where players of the game need to unveil clues to proceed to further steps. The first to complete the "game" gets prize money and an eReader signed by Dan Brown:

This is the first time we're building a narrative beyond just the words in a story so we're excited about the experience.

Sounds like a fun way to spend the weekend waiting for DB's new book to drop?
