250 Largest Cities of the World with letter hints, by country
Take the list the 250 largest urban agglomerations of the world by population: for each country that has at least 3 entries, list its cities in order. You are shown hints for cities that aren't the largest of their countries.
For the 2nd city of a country you are shown the second letter, for the 3rd you are shown the initial letter, for the 4th the first two letters and so on - but you will always have to guess at least the last letter!
You will also have to guess the country names! Countries are sorted by number of cities in the list and then alphabetically
