NOTES: Type LOWER CASE and DO NOT use punctuation. Scores are based on PERCENTAGE OF TOTAL POPULATION OF THE 5,000 CITIES REACHED (shown just below the map to the right). You only start with 15 minutes but there are MANY TIME BONUSES (see below) which can increase your time substantially. TIP: Try for categories first to get some extra time rather than small cities or focusing too much on one country. Markers are initially placed so that largest cities are ON TOP of smaller ones. City's marker will disappear when it is guessed. TIME BONUSES are given for the largest as well as top 3, 5, 10, 25 and 50 largest cities in a certain # of countries, as well as cities of a certain size (coded by color), countries completed, cities in certain pop ranges, total % of population of all cities, and total cities completed. I attempted to use official census results as much as possible but had to rely on non-census sites for some less than 100K cities in Asia and Africa mostly.
