Countries, US States and Capitals on the World Map by 3 Common Letters
Type any 3 consecutive letters of a country/state/capital to make it appear provided they are also 3 consecutive letters of at least one other country/state/capital!
Type any number to highlight answers that don't share any 3 consecutive letters with other ones!
EXAMPLES: - you can only get SUCRE by typing CRE as that appears in 'democratiC REpublic of the congo', SUC and UCR don't appear in any other answer; - you can only get reykjAVI by typing AVI because that appears in brazzAVIlle.
In order not to overlap US States, 'United States' only highlights Puerto Rico
