World 20 Circle Population Challenge

Directions

The object of this quiz is to place 20 circles of radius 1000 km on the map so that they contain the largest total population.

When you begin you’ll be given a 1000-km radius circle centered on the map. Move it using the mouse and click SUBMIT. You will be given a score for that circle corresponding to the total population contained within it based on world population density at https://human-settlement.emergency.copernicus.eu/index.php. Try to complete all 20 circles with the highest total score.

Any INTERSECTING areas are only counted one time, so no population will be counted more than once.

World Closest 1M+ Agglomeration Random Location Challenge

The object of this quiz is to name to closest World 1M+ agglo to each purple marker that appears. When you begin the quiz you will be placed in a random location within a continent and between 60 North and 55 South latitude (might be over a body of water, but won't be over an ocean) which will be denoted by a purple marker. Name the closest 1M+ World agglo to this marker by typing in the main city/agglo name followed by a '.' (period). You will then be given a score up to 100 (100 being the closest 1M+ agglo) based on how far away your agglo is in relation to how far away the closest one is. You get 25 agglos for a maximum of 2500 points. If you name a agglo that has the same name as another possible answer, don't worry - the closest agglo of that name will be chosen.

Like this quiz, there are several quizzes where the Start green button just doesnt appear. The favorite button also seems to slide behind the black right side. There is some glitch in a lot of quizzes
