Countries of the World by Borders and Alphabetical Order
Starting from Belarus; name every country (with a border) in the world by naming the country first in alphabetical order that borders the country you previously wrote.
Including overseas territories and exclaves.
When a country has got no borders left, go to the closest country with a border.
The quiz only includes countries with 1 border or more. I've changed the second caveat as it was quite misleading. Or perhaps you consider the antartic borders?
