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 SECOND 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 2nd largest city accepted in that square (100 being you named the 2nd largest city). If you guess the largest city it will be based on the ratio of the 2nd largest city's population to the largest.
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 250-500K) 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.
Quiz Takers 
If I could remember all of the cities in metro LA, PHX and DFW and all of those damn cities in southern FL I’d have them all.
When it comes to Florida, get ready to learn a bunch of cities with the word “palm” in their names!
Could we get a version of this quiz for 75K and 50K as well? It’s like a checklist then for the major colors on the All Places quiz.
i know them, i cant spell them
Has this been updated without the DATA UPDATED changed? I see al these ‘new’ cities all of a sudden
Oh yeah this one is basically live – I’ll changed the Date Updated to say Live.
These kind of changes could be the last straw for people with autism 😛
I would love to see this format for other geographical regions!
I remember you had something like this on sporcle, with random country/state poping up with 10 seconds to answer the largest city bot yet answered. Or something like that. Loved it.
Same. Also the one where you were given randomly the first two letters of a US city and you could skip or guess until you time ran out
I also loved both of the above-mentioned quizzes!
