First choose a difficulty by typing ‘beg’, ‘int’, ‘adv, or ‘exp’. Then, enter 10K+ population cities and all 10K+ population cities within a radius based on the population of the city you guessed will fill in. When you have at least 25 countries, the countries remaining will be shown. In other words, a large city will have a bit larger radius to cover other cities than a smaller city would.

A higher difficulty level means smaller circles, but still in the same size proportion to each other based on populations.

hugequiz Premium members will see the 25 largest missed cities at the end of the quiz as large, purple markers.

There is also the option to play a 3-hour (basically untimed) version of each level. Simply enter a ‘u’ before a level choice to play a 3-hour version, for example ‘ubeg’ or ‘uadv’ – your score will not be saved for these.
