First choose a level by typing ‘beg’, ‘int’, ‘adv’ or ‘exp’ – beginner is 2,500,000, intermediate is 1,000,000, advanced is 250,000 and expert 100,000. Then, begin naming 1K+ cities. All cities starting with the city you chose and moving outward will begin filling in until you’ve hit a total population equal to or greater than your chosen level’s threshold. For example, if you choose ‘beg’ – the threshold is 2,500,000. If you choose ‘Tijuana’, then Tijuana will fill in and because its population is under 2,500,000, successive cities moving outward from Tijuana will fill in until the total population reaches at least 2,500,000. If you chose Mexico City, only Mexico City would fill in as its population already meets your threshold.

Premium members can now also play a 3-hour time limit ‘custom’ coverage quiz of any population from 50,000 to 5,000,000, simply enter the population followed by a ‘.’ instead of choosing from one of the four levels, i.e. ‘750000.’ Quiz score is not recorded for the custom coverage option.
