Start with Chile. Then guess its southernmost neighbour (by point on land). Then guess the southernmost neighbor of that country, etc... When you reach a dead end, go back and choose the next southernmost-neighbor. Finally, when you're done with continents continue onto the islands.
Overseas territories and regions don't count
Dubious land borders not considered: Sri Lanka/India, Qatar/UAE
