Choose any 50K+ World city, then continue naming 50K+ cities which are within 500 km of any previously named city. Please note – North/South America and the rest of the world are considered separate sections on this quiz. The game will not end if you haven’t begun one of them and then ‘jump’ over to it to begin working on it. So you get one free city to choose outside of the 500km distance if you want to start working on the section you haven’t started. But once you have started both NA/SA and Rest of World, you cannot guess a city outside a 500km circle or the quiz will end.
Naming notes: many places have similar names. For example, “Brest” is not unique. To choose Brest, France, simply type “brestfr”, using the first two letters of the country name…another example is “londonun”. Also, some answers require typing in other answers you may not want to guess. In this case, if you want to answer “Hamburg”, simply type it..”Ham, Belgium” will not be chosen. If you want simply “Ham” type ‘ham.’ with the period at the end. One other issue is multiple cities in the US with the same name, for these type in the state abbreviation and ‘us’ at the end – i.e. ‘jacksonvilleflus’
