First choose the number of cities by typing ‘100’, ‘250’, '500', '1k' or 'all' – then try to achieve the highest population among the largest English cities (min 500 population) you chose. Quiz is not timed.
hugequiz Premium users have the option to choose any number of cities to play the quiz with (stats are processed but score isn't saved). Simply enter #(number of cities)# to play the quiz with any number of cities from 25 to the maximum. For example, to play the 300 largest cities, type #300# to begin the quiz and you will play it with the 300 largest cities. Entering #all# will play it with all cities - all cities will also be chosen for any number chosen above the total.

They are part of Denmark, they just don’t fill in on the map on the quiz cause they are smaller.
At the end of my game it still shows vatican city in the missed list.
The games stopped by itself when I reached 47/47.
Transnistria is a country especially if you’re counting kosovo which is in a weird UN state of not but is
None of the major quiz sites count it as a country so I don’t.
Sorry but acording to UN “Kosovo” is not a country
It’s regarded as a country by other large quiz sites, so I regard it as one as well.
According to MOST (101) countries represented in the UN, Kosovo is a country. The few holdouts are literally insane. It’s been 15 years. Time to suck it up and deal with it already.
Shouldn’t the game automatically stop once you have the 47 countries?
yeah it does – maybe just a one-time bug? i just ran it and it ended after 47.
Same has happened for me just now. Got all 47 and clock still counting down
very odd – i’ll take a look, but i’ve done it a few times and it always ends at 47. did it say ’47/47′ for the countries gotten?
