This game is lots of fun and a real challenge, even for those of us who have circumnavigated the globe and think they are pretty good at geography.
Here's how it works:
You have a world map in your browser. After you click START! you are shown the name of a city, for example Paris, and you have to click on the map, hopefully somewhere in the center of what you know to be France. The points you get depend how close you are to where Paris is actually located and the speed at which you place your little pin. So no dilly-dallying!
FYI the first (and so far only time) I played this game I got to Level 10 out of 12 and scored 387,101 points. My Travel IQ is 113, which is not too bad I guess. The map is small, but that's part of the fun!
So give it a try!
