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 
i changed this to remove Frankfurt – it will be under its full name in a quiz for 15 letters.
Newcastle? also please accept Genichesk
This series of quizzes uses the full official name for cities, so it’s Newcastle upon Tyne. Same for Stoke and Hull for instance.
yeah i tend to use full city names for counting letters…will add that alternative.
then why do you use Frankfurt and not Frankfurt am Main
If you have Newcastle as an alternative won’t the city appear in two quizzes, this one and the one with more letters? I’ve seen quizzes with Frankfurt and Frankfurt am Main but with such an amount of quizzes one can excuse a bit of inconsistency here and there.
