The 39 Clues - Search for the Keys is a board game released in 2009 based on the 39 Clues. Players choose a private jet, each representing 1 branch. Lucians go first, and you travel around notable locations (Paris, Vienna, Angkor and Cairo being some) to collect keys. Collecting keys involve naming cities based on clues. Clues involve cryptic references (It's hard for the pilot to relax, indicating Los Angeles, because their airport is symbolised by LAX), flags and anagrams.
