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 
They are part of Denmark, they just don’t fill in on the map on the quiz cause they are smaller.
At the end of my game it still shows vatican city in the missed list.
The games stopped by itself when I reached 47/47.
Transnistria is a country especially if you’re counting kosovo which is in a weird UN state of not but is
None of the major quiz sites count it as a country so I don’t.
Sorry but acording to UN “Kosovo” is not a country
It’s regarded as a country by other large quiz sites, so I regard it as one as well.
According to MOST (101) countries represented in the UN, Kosovo is a country. The few holdouts are literally insane. It’s been 15 years. Time to suck it up and deal with it already.
Shouldn’t the game automatically stop once you have the 47 countries?
yeah it does – maybe just a one-time bug? i just ran it and it ended after 47.
Same has happened for me just now. Got all 47 and clock still counting down
very odd – i’ll take a look, but i’ve done it a few times and it always ends at 47. did it say ’47/47′ for the countries gotten?
