Type 'easy' or 'hard' to begin the quiz. Easy is a 2-degree grid, hard is a 1-degree grid. Then, try to name the SECOND LARGEST Spain city in each grid 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 2nd largest city accepted in that square (100 being you named the 2nd largest city). If you guess the largest city it will be based on the ratio of the 2nd largest city's population to the largest.
At the end of the quiz the 2nd largest city will show in each unanswered square, and for those answered the 2nd largest city will be listed next to your score if you didn't answer it.
Quiz Takers 
I ended up cheating for 2 missing cities in Russia… so that I could finally finish this quiz! I can now try finishing it with less circles
Why did Porto, Spain not work?
You mean Portugal? It’s just under 250k.
wikipedia says otherwise, and we all know that wikipedia is never wrong /j
In this case Wikipedia is actually more up to date.
If the quiz was about agglomerations, Porto would have over a million.
Why can i not give up whenever I want? It should be able to like on any other quiz, instead i have to wait until the timer is over.
it’s because you have to actually finish this quiz for a score to mean anything. finishing without covering all cities will give you a meaningless score because the object is to get the least number of circles.
