Upon clicking START you will be shown 5 circles, one at a time, with increasing radii: 50, 100, 250, 500 and 1000 km. The object is to move the circle to the location such that it covers the most amount of people, based on Europe population density data. You are scored based on how many people you cover compared to the maximum possible (score is based on the ratio of people in your circle compared to max possible - score is not an exact ratio but falls faster than that).
PLEASE NOTE: ALL of Turkey is included in counting population (not just European portion), and the portion of Russia west of 61.5 degrees E (just east of Chelyabinsk). Nothing outside Europe (such as Africa or middle east other than Turkey) is included toward the population count within a circle.
