Can you guess these 20 countries, highlighted in blue, on a topological map of the world?
A topological map is a type of diagram that has been simplified so that only vital information, such as borders, remains. Other details, such as size and shape, have been removed.
Do you love typing so long and fast that your fingers ache? Have you nothing better to do for the next hour? Draw the map of the world by entering ALL country borders, including seas, oceans, gulfs, bays, lakes, and of course other countries.
