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 THIRD LARGEST city in each grid 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 3rd largest city accepted in that square (100 being you named the 3rd largest city). If you guess the largest city it will be based on the ratio of the 3rd largest city's population to the largest.
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 3rd largest city will show in each unanswered square, and for those answered the 3rd largest city will be listed next to your score if you didn't answer it.

the quiz doesn’t seem to be accepting Neuenburg am Rhein as a city :/
It answers by just typing ‘Neuenburg’
I am afraid it does not do this…
Ah sorry, now it’s good. May have to refresh the quiz.
thanks!
was typing Bietigheim Bissingen and it took the first part & I thought what finally you no longer have to type the full name and then after I hit end quiz I see that I missed that exact city because supposedly there’s another town called Bietigheim and it took that one instead :/
hate when that happens
