Worked solutions for each puzzle can be found on the puzzle page, and the full answer log is also available. Credits for the 2008 Competition.

Many of you have no doubt noticed that there is a mysterious "Metapuzzle" this year. There is no PDF file for this puzzle. Sufficient information to solve it is already available. It is not worth any points and in no way affects positions on the ranking table, but it does give your team a cool bonus.
