At the start you will only see the dots of the 3 largest agglomerations in the world. For every other city the dot will be revealed when you guess any of the 3 closest larger cities.
This 'dot' will be blue if it represents a capital or an agglomeration containing a capital; it will be red if it represents an agglomeration without a main city.
