Type 'easy' or 'hard' to begin the quiz. Easy is a 2-degree grid, hard is a 1-degree grid. A grid will be placed randomly on the map. Then, try to name the 1st-5th largest city in each square, depending on what the square label displays (so if the label says '3rd Largest' you are trying to name the 3rd largest city in that 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 target city accepted in that square (100 being you named the correct city).
At the end of the quiz the target city will show in each unanswered square.

Find the box where you type the answer, would be a good game!
Huh? It’s the white guess box above where the Street View shows.
I’m pretty sure I’ve got the highest and lowest scores on this particular quiz (for now), and I’m very proud of it. I paused a round earlier, left it a few hours and it racked up a score of -14,000.
do you only have a set number of places? seems like stevenage, st albans and sutton coldfield appear every round?
100 largest uk places are the basis, per the directions
I got Wallasey in a game just now which definitely isn’t in the 100 biggest places in the UK?
