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 SECOND LARGEST city in each grid 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 2nd largest city accepted in that square (100 being you named the 2nd largest city). If you guess the largest city it will be based on the ratio of the 2nd largest city's population to the largest.
At the end of the quiz the 2nd largest city will show in each unanswered square, and for those answered the 2nd largest city will be listed next to your score 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.
