Where in the World Is Carmen Sandiego?

This is a Facebook puzzle game released in 2011. Players began the game in the Chief's office in the ACME headquarters, where they could check which cases were available to choose. After accepting one of the cases, players started by the traveling to the first crime scene. Players travel through the city to search for and collect clues; the city clue hinted at the next geographic location to fly to, and the ID clue at the identity of the thief for that case.
