Type 'easy' or 'hard' to begin the quiz. Easy is a 15-degree grid, hard is a 10-degree grid. Then, try to name the LARGEST city in each grid square which fits the category label for each square. To name a city, you must first click on the grid square to make it have a GREEN border. Then, type in the city answer for that square followed by a '.' (a period). You are given a score from 0 to 100 based on your answer's population compared to the largest city accepted in that square (100 being you named the largest city).
LETTER: means the city starts with that letter.
NUMBER RANGE: (such as 2-5, 10+) means the city contains that many letters (excluding spaces and special characters).
POPULATION RANGE: (such as 50-100K) means the city has that range for its population.
2+ WORDS means the city name has 2 or more words (words denoted by a space or hyphen).
At the end of the quiz the largest population missed answer will show in each unanswered square, and for those answered the largest city will be listed if you didn't answer it.
Quiz Takers 
Why is the time limit so ridiculously short. I had time to enter 10 countries, am I missing something?
i’ll increase it. there are time bonsues too.
It’s a great quiz, the research for it must’ve been tough. Senussiya should probably count, and there were the Ovambo kingdoms such as Oukwanyama, Ondonga etc., also loads more in the Great Lakes but you got the main ones. Nkore is the right name rather than Ankole, it was only called Ankole after it was combined with some minor states under british administration.
IMO this would work a lot better with a map
I think that would be a diffferent game. Maybe more fun, but less challenging (for me at least)
i changed this quiz to reflect all world countries in 1900, not just those with a population estimate at that time.
