Google has released a game for the Da Vinci Code in time for the release of the movie. The site is http://flash.sonypictures.com/movies/davincicodequest . You must have a google account (go to www.google.com/ig , login and search for da vinci quest google), and must be from either US, UK and AU.
It may not be rocket science but still the game is fun. Last day is tomorrow so I suggest you play it asap.
Some Da Vinci Code Fun...
