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.

Intrigued by the alphabetization of answers 20 and 21. Is there a reason for that in some aspect of transliteration I don’t understand – or is your order stored separately from using the names to alphabetize? (Pretty sure you’re not using ISO 2 letter codes to alphabetize, because then the order is further out of whack – 11 is too soon, 14 is too late …)
No was just my mistake 🙂 Fixed now.
I’d argue #2 has black on it in the same way that the flags of Bhutan or Kiribati or Sri Lanka have black. The outline of the object isn’t the same colour as the background or the object itself like in the flags of Afghanistan or Oman or Uruguay.
Yeah I’ll remove Cambodia from the correct list.
Isn’t black just a shade of white?
so you’d say the flag of Jamaica is green, yellow, and white?
