Type 'easy' or 'hard' to begin the quiz. Easy is a 5-degree grid, hard is a 2.5-degree grid. The grid will be randomly placed on the map. Then, try to name the largest cities 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.
AK and HI are NOT included in this quiz.
At the end of the quiz the largest remaining city you haven't named will be shown in each square.

My adopted home is the #1 Hardest! Is that good or bad?
hempstead doesnt count?
It’s a township – those typically are not counted in my city quizzes.
I’m confused why Metairie is included. Everything I searched for said it was not incorporated during the time period it’s included in. I think I found your source, and I don’t know why they include that either.
I think maybe the census included unincorporated places back then? Not sure.
Holy crap. The city at #99 in 1950 jumped SEVENTY (70!!!) spots in 1960.
I wonder if any city has come even close to that 70 position jump between 1950 and 1960…
Oh wow, that really is something. I had no idea that 1950 #99 was such a small city only 70 years ago…
Interesting find, Ovamiat!
According to Wikipedia, in 1958 the city “doubled in size” due to annexation, not sure whether the doubling refers to population or land area or both. There was certainly plenty of actual population growth, but some of it is just changing boundaries.
It got bigger because of advances in AC during the 1950s

Hey Darin, Sherburne, MA is actually the same town as Nantucket (they changed the name in 1795) so you might consider letting “Nantucket” count, unless you think people should know about the town’s archaic name to get the point.
will add as alternate.
Great, seems to be working!
Ah, I was very confused what happened to sherborn Mass was included when its still less than 5k now, but that makes much more sense
