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.

russia should use federal subjects not federal districts, romania should use counties instead of development regions, and republic srpska should be allowed for bosnia’s largest division
Yeah i wanted to make the divisions kinda match between countries, so they are basically the largest divisions of each, in a few cases they may technically not be an administrative first-level division, but I didn’t want countries to have larger divisions than the ones shown in this quiz.
romanias development regions are purely statistical
yes I realize that, some others are not ‘official’ as well but wanted to have the ‘largest’ regions for each country.
there is actually a standard list of these divisions, ISO 3166-2
yes, but I’m not going by that 🙂 didn’t want any with tons of divisions – some first-level are well over 100.
I was robbed of the answer for Uzbekistan because it didn’t accept a K instead of a Q. The K is much more common in English.
