Type 'easy' or 'hard' to begin the quiz. Easy is a 5-degree grid, hard is a 2.5-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).
AK and HI are NOT included in this quiz as they often have grid squares with only one answer for this quiz.
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.

Updated – welcome new CSA’s since 2023!
This quiz doesn’t make much sense. “Combined statistical areas” based on what criteria? These are clearly not based on metropolitan areas. Just speaking of the western US: There’s nothing for San Diego/Carlsbad CA, Bakersfield/Visalia, CA, Santa Rosa/Napa, CA, Flagstaff, AZ, St George, UT, and whatever that thing is on the map in western Colorado is mostly rural and ski resorts, and doesn’t include Grand Junction. And there’s all kinds of cities in Texas missing from the list. It seems like a five year old decided what should be included here, and not.
CSA based on the OMB’s definition which the census uses (see directions).
Why isn’t Phoenix on this quiz?
Well, I think it’s basically because Phoenix isn’t a CSA. As to why, I think it all bows down to the criteria used by the guys who think this stuff up. San Antonio and Austin for instance aren’t there either.
Yeah. Five major metropolitan areas aren’t considered CSAs: San Antonio, Austin, Anchorage, Honolulu and Phoenix.
I see two cities of over 1,000,000 people, three state capitals and three largest cities in their states in those five.
And that doesn’t take Laredo, Billings and Sioux Falls into account!
You can add San Diego and Tampa-St Petersburg to that list.
Louisville now added to this list that makes no sense whatsoever
