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 European 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).
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.
Quiz Takers 
btw can you also create largest cities per French region quiz? I just want to name cities in Ile-de-France but it’s split into several departments so there’s no convenient way to do it
I think the “Top Cities:” feature is broken on this quiz. I only named 6 cities, and it says I’ve listed the top 1,480 cities. This happens in every department. I am running the latest version of Firefox.
this has been fixed.
tried Seine Saint Denis now and in the 50 hardest table there was
Saint Denis – villetaneuse%
Montreuil – dugny%
and in the missed table all of the other cities (including the previous 2 with the correct city before the %)
it’s because you were the first playing that department.
might be an issue because I’m the first one to take the quiz but for some reason all cities were showing up in the missed list (including the ones I got)
