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 Asian cities (min 50K population) 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.

Also it would be nice if the missing ones would be listed sorted by population.
The missing ones are sorted by most to least population – which prefecture isn’t showing it that way?
I feel like most of them, just did Hyogo and the first missing result was a city with 15k and the last missing result was a city with 150k and then Kakogawa with 260k near the middle of the list. I have seen some that seemed to be sorted correctly. Could it be that the ones no one played yet are sorted randomly? I didn’t focus too much on it but I feel like the ones others played were sorter more accurately.
ah yeah that’s it – if you are the first one they might be off a little.
Yea I did another one with people on the leaderboard and it is sorted correctly, might not actually be an issue.
