Players move around the board to visit landmarks and look at clue cards so they can figure out a mystery phrase. Each clue requires a different mechanism to solve (a mirror to reverse the letters, a decoder box laid over the card to reveal part of the phrase, some of a special decoder tool). Some are simply riddles or puzzles to solve. Some clues also require the player to move to the library at the center of the board and retrieve a card with more information. Alternatively, players might need to visit the Louvre and examine a painting. When the mystery phrase is solved, players garner further points by answering questions relating to the clues.
