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 
doesn’t make sense that some multi word cities are included if the first part is 5 letters and some aren’t
for example Torre del Greco included but Torre Annunziata isn’t
Gioia del Colle is included but Gioia Tauro isn’tRosny-sous-Bois included but Livry-Gargan isn’t etc.
I have adjusted these – they are based on the full name and I had some computing total letters off the partial shortened name. But for some cities very often referred to using a shortened name (like Frankfurt) I go with the shortened, common name.
these were just 3 examples there are dozens of others too (like in France every city that’s “sur” or “en” something)
it’s a good thing that we don’t have to type full names in general but they shouldn’t appear on quizzes like these which ask for an exact amount of letters
for some reason the markers for Halle, Essen, and Lille aren’t disappearing (even tho they’re counted into the stats)
fixing this now – thanks.
