Kind of rolling off of Techfan's How Many Countries Can You Name thread, this is the Traveller IQ Quiz. Basically, it names a city and a country, and you have to click where it is on the world map in a certain amount of time. The map is COMPLETELY unlabeled, and rather small, so you really have to be savvy. But why not give it a try?
I just played it (for the first time in a while) and got 377,369, and have a Traveller IQ of 112. Died on level 10. Jeez, it's impossible at that point.
