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.

So this is how I find out that Lake Worth, FL changed its name to Lake Worth Beach! Very tricky, Floridians.
probably a few more next week…other topics this week.
Also, a few places seem to have slipped into the list: Islamorada, Defuniak Springs, Lower Red Lake (not incorporated), and Castle Pines. South Orange, NJ probably shouldn’t be on here either unless you want to count “Township” for all the NJ townships, in which case a number of towns would be missing. I know you usually count hyphenated names as one, but it seems like Parsippany-Troy Hills might be a reasonable exception to the rule.
Islamorada, Castle Pines are shortened accepted answers to their full names (Castle Pines North, Islamorada Village of Islands) – census lists Defuniak as ‘De Funiak’…South Orange is known as South Orange Village, Lower Red Lake is listed in the census data among cities/village/etc like other incorporated places, don’t know why. I did not include places with ‘Township’ appended to the end. Fixing the ’50’ and ‘100’ issue as well.
