Try to guess all countries in the world in order of their westernmost point on land, by longitude. When you guess each country it will be illuminated on the empty map.
Excluding territories, autonomous regions and overseas departments (eg French Guiana)
Includes states and islands in the metropolitan country
For island countries, we consider the longitude for the westernmost ISLAND
Good one! I think you should count Canary Islands for Spain, since it is not a territory or an autonomous region but just another regular Comunidad Autónoma, like the rest of Spain.
