Coverage

Enter a World 1M+ city - all other 1M+ cities within 1000km will also fill in. Try to fill in all 1M cities in the smallest number of circles. Countries remaining will display when you have completed 80 countries. For Khartoum, enter 'khartoum.' with the period to prevent entering Khartoum North. For Hyderabad, there are two, so enter 'hyderabadin' for India and 'hyderabadpa' for Pakistan. Also there are 2 'Taizhou' cities in China. To name the southernmost (slightly larger) one, type 'taizhou1' - for the other type 'taizhou2'.

You start with a blank map. Double-click on the map to create a circle of 500km radius centered on that location. All World 50K+ cities within that circle will appear and count toward your total cities. The object is to cover as many cities as possible in 50 circles. You can click within an already-created circle as well, however you may have to zoom in slightly so you aren't clicking on an existing city marker.

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' - if a place name outside the US has multiple locations in a country you can use 'fuzhouch1', 'fuzhouch2' etc for the Fuzhou's in China.

First choose a difficulty by typing 'beg', 'int', 'adv, or 'exp' - Beginner is 2 degrees latitude, Intermediate 1 degrees, Advanced 0.5 degrees, and Expert 0.25 degrees. Then, enter 50K+ population cities and all 50K+ population cities within that latitude will automatically fill in.

HOWEVER - for this quiz you can enter any 50K+ city for your first choice, but successive cities must be already within a blue band for you to answer them, so you must 'expand' the blue area in the north and south directions, you can't start a new blue band with a gap away from a currently blue shaded area.

First choose a difficulty by typing 'beg', 'int', 'adv, or 'exp' - Beginner is 5 degrees longitude, Intermediate 2.5 degrees, Advanced 1 degrees, and Expert 0.5 degrees. Then, enter 50K+ population cities and all 50K+ population cities within that longitude will automatically fill in. PLEASE NOTE: Your first two selections must be one in each of the two separate regions - the Americas and Eurasia/Africa/Oceania. So if your first guess is 'New York' that covers the Americas, and your second guess must be a city in the Eurasia/Africa/Oceania section. Then you will have two bands you can expand independently as you play the quiz.

HOWEVER - for this quiz you can enter any 50K+ city for your first choice, but successive cities must be already within a blue band for you to answer them, so you must 'expand' the blue area in the east and west directions, you can't start a new blue band with a gap away from a currently blue shaded area.
