The object of this game is to click on successive bordering countries to ‘travel’ through up to 25 countries with the objective of accumulating the smallest total population among all countries traveled through. Borders are land borders only, including causeways but not including only man-made structures. Borders include dependent territory borders, populations also include territories. Population in millions is shown. You must complete 25 countries for your score to save – so for example you can’t get ‘stuck’ somewhere like South Korea with no other countries available to click on unless it happens to be your 25th country clicked.

For example, you can begin by clicking Russia – your next country can be any country bordering Russia, such as Ukraine. After clicking Ukraine you can choose any country bordering Ukraine except a country you have already visited (in this case just Russia). You must continue along your path and can’t click a bordering country from a previously-clicked country unless it borders the country you just clicked.
