incarnation of the TV
show had the final round
The Youngsters were led out to a giant map of a continent. (Never North America). Then, the host would simply name a country, and they would have to run and stick a giant flag on an indicator on the appropriate country. If you used up a certain percentage of the flags (x number of countries), you won.
They changed this because young people in our country are simply not taught enough geography for this to be fair. In fact, almost no one ever won. Which was why I enjoyed watching it. :)
