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 changed this to remove Frankfurt – it will be under its full name in a quiz for 15 letters.
Newcastle? also please accept Genichesk
This series of quizzes uses the full official name for cities, so it’s Newcastle upon Tyne. Same for Stoke and Hull for instance.
yeah i tend to use full city names for counting letters…will add that alternative.
then why do you use Frankfurt and not Frankfurt am Main
If you have Newcastle as an alternative won’t the city appear in two quizzes, this one and the one with more letters? I’ve seen quizzes with Frankfurt and Frankfurt am Main but with such an amount of quizzes one can excuse a bit of inconsistency here and there.
