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.

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.
