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 
“50 Missed” doesn’t display missed answers. It seems to show random correct answers.
Yeah for some of these municipalities quizzes where size isn’t factored into the quiz it will do that.
Why cant u type inn fullscreen-version? Would be a great quizz if that was possible
Yeah it’s cause of how Google Maps works, can’t show anything but the map. You’ll just have to maximize your browser window instead.
Added the new 357th municipality of Norway – border is not exactly correct but is close 🙂
