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.

I love NYC, but not enough of a New Yorker to know of any alternative names I should accept, or any stations I might have missed – let me know in the comments! (Will remove comment when fixed).
Hello, we usually say the street number and then the word street or st behind. For example, 34st or 34th street. Same thing for the avenues, blvds, and parkways. It just sounds weird saying for instance,” hey want to go to northern. They won’t really know what you’re really talking about. Put Union Turnpike instead since it doesn’t really make sense. Maybe put Avenue U as well because I couldn’t really figure out that it was ave u. Some alternative names can be like “Hudson Yards”, “Columbus Circle”, or “Union Square.” This is basically all the suggestions I have found as a New Yorker for now.
I feel like 34th or 34st would be good enough
I’ve made these updates – for numbered streets I allow just the number (such as ’34’ or ‘140’).
Thank You
