Type 'easy' or 'hard' to begin the quiz. Easy is a 15-degree grid, hard is a 10-degree grid. Then, try to name the LARGEST 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.

For Denmark, I assume you’re claiming that it borders Germany and Sweden (via bridge). By the same measure, Sweden would border Denmark, as well as Finland & Norway. But Sweden is also a correct answer here.
Does Denmark border another country I’m not aware of?
Denmark borders Canada since 2022 via Hans Island.
Makes sense. But for Sweden, doesn’t it border three countries: Norway, Finland, and Denmark (via the Oresund bridge)? I believe you count Bahrain and Saudi Arabia as bordering countries due to the causeway link – would the same also apply to Sweden?
Denmark isn’t included. Only causeways, which is why Singapore borders Malaysia for example.
Morocco borders Spain, Algeria, Mauritania, doesn’t it?
Not Mauritania, I do not include Western Sahara as part of it for country bordering quizzes.
I think UK should also be the right answer (Ireland, Spain)
Think the quiz counts Cyprus too.
UK has Cyprus too.
