The Da Vinci Code WebQuests (also called The Da Vinci Code Challenges) are a series of web-based puzzles related to the bestselling 2003 novel The Da Vinci Code, as well as the 2006 film. There have been several web quests, none of which directly related to any other. Probably the most well known is the game run by Google, though it was ultimately met with much more public criticism than the other various games.
