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 50K+ cities in each square IN ORDER. 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).
The squares will start with '0/5' (or maybe fewer cities if less exist in that square). Click on a square and enter the largest city in that square not yet answered (so, the largest city if you have yet to answer a city in that square). You will then have '1/5' and need to click on that square to name the 2nd largest city, and so on until you complete all the cities up to 5 (or less if less exist). If you name an incorrect city in a square it becomes 'locked' and turns red and you can no longer accumulate cities in that square.
You receive 1 point for the largest city in a square, 2 for the 2nd largest, and so on.
At the end of the quiz the largest remaining city you haven't named will be shown in each square.
Quiz Takers 
Is it really written “Serre Kunda”? I’ve only ever seen “Serekunda”
It’s either according to the Wiki page.
Is there an explanation for why the data used in this are different from those used in other quizzes? I ask because some cities are missing compared to other quizzes and others require specific spellings that I didn’t get the first time.
Yeah this quiz was a little different data because I was going regardless of population and pulled a different data set. Let me know alternate names I should accept though and I’ll add.
Kuwait has a city with a population of 281,665 in this map. No source in the entire internet claims ther is something like this.
The city with the largest population for Kuwait should be either Kuwait city (well Johannesburg was counted, so why not Kuwait City?) or it should be Al Ahmadi (around 600k population).
None of the largest cities in Kuwait fill this city up
i’ve fixed Kuwait to match the cities on the World population quizzes.
