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.
Is there any reason I’m not aware of why Tromsø isn’t included? Current population looks to be over 50k but that might be a similar situation to Muscat I don’t know of.
You might be looking at the full municipality – city proper is a little too low:

Saigon (Ho Chi Minh) should be accepted under both names as they’re equally used and thus should be on both the 6 and 9 letter quizzes.
Also, since Mumbai/Bombay is a 6 letter city no matter which of those two names you use, both should be accepted.
On most quizzes Saigon is accepted as an alternative for Ho Chi Minh City but for this letter-based series it must be one or the other as no city should appear on more than one quiz. As the official name for the city is Ho Chi Minh City that name should prevail over Saigon which, as useful as it is as an alternative name, it’s an outdated designation.
