You have 5 minutes and it starts as soon as you open the link, you have to type countries. I got 48 which is apparently below average, I did get the country that's completely surrounded by another country that's named for its position at the bottom of its continent though.

When it's finished it shows you the percentages of people who got each country. Only 72% of people got this country, the country most of us are in now, we're not as famous as we were.
