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 largest UK 1K+ cities in each square IN ORDER. 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).
The squares will start with '0/5' (or maybe fewer cities if less exist in that square). Click on a square and enter the largest city in that square not yet answered (so, the largest city if you have yet to answer a city in that square). You will then have '1/5' and need to click on that square to name the 2nd largest city, and so on until you complete all the cities up to 5 (or less if less exist). If you name an incorrect city in a square it becomes 'locked' and turns red and you can no longer accumulate cities in that square.
You receive 1 point for the largest city in a square, 2 for the 2nd largest, and so on.
At the end of the quiz the largest remaining city you haven't named will be shown in each square.
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.
