The Code: Crack the Code Wiki

The Ultimate Challenge for the BBC program The Code was solved on August 16th, in large part thanks to the work done on this site. You can read final thoughts and farewell from the participants here.(and also in the discussion section of this page) Please feel free to introduce yourself !

The winner of the finale, Pete (pdr77), can be seen here holding the trophy. A video of the finale is now shown on the BBC home page for the code, here.

This stage of the competition may have been solved, but it is still well worth attempting the puzzle yourself. Errata aside, it's incredibly well constructed and a thing of great beauty. I recommend the experience to anyone. If you're new here, don't know where to start, or want hints for places you're stuck (without spoilers) then go to: How to Crack The Code. With the exception of that page, THIS SITE IS NOT A GUIDE, but a record of our steps along the way, which only covers up to a certain point in the problem. While there is a wealth of useful information, be aware that many pages are incomplete and contain spoilers and/or mistakes. -pqg
