This geography game, the Traveler IQ Challenge,comes via Fimoculous. You can test your knowledge of U.S. capitals, major cities, and world cities and capitals. I did very well on U.S. capitals, fair on world capitals. The goal is to click on a map to identify the location, and the faster you do it, and the closer you get, the more points you score. The difficulty increases with each round of the game. It's pretty addictive - and educational.
