World 10 Circle Population Challenge

The object of this quiz is to place 10 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 10 circles with the highest total score.

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

World 20 Circle Population Challenge

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 50K+ Expanding Circle Population Challenge – Your Location

First enter a level by typing '25M', '10M', '5M', or '1M' - you begin with that population figure (shown by 'Population Remaining'...the bigger the number the easier the quiz). The quiz will center in on your location - you must have your browser's location figure on. A pink marker will be placed at this location.

The object of this quiz is to accumulate 'Population Gotten' by typing in world 50K+ cities (see naming note below) moving outward from your marker without skipping cities. Any 50K+ city skipped will count against your Population Remaining. Any 50K+ city guessed correctly counts toward your Population Gotten. Population Gotten is your score for this quiz, this is the number you want to have as high as possible - it is the sum of the population of all your guesses.

Naming Note: You must add a '.' at the end of each city name for it to take - this is to prevent typing in another city name which is the first few letters of the city you wanted to type. There are a good number of these so to make it easiest I am simply requiring a '.' after each name you enter.

There are no time bonuses on this quiz.

A circle will be drawn going out to your last guess and showing that guess as a green marker and any missed cities that were closer as a red marker. All members can mouseover the green markers to see what their name, population and rank in terms of closeness to your location (i.e. #10 is 10th closest 50K+ city). hugequiz Premium members can hover over the red markers as well to see the missed cities and their info.

World 50K+ Population Radius Coverage

First choose a difficulty by typing ‘beg’, ‘int’, ‘adv, or ‘exp’. Then, enter 50K+ population cities and all 50K+ population cities within a radius based on the population of the city you guessed will fill in. When you have at least 160 countries, the countries remaining will be shown. In other words, a large city will have a bit larger radius to cover other cities than a smaller city would.

A higher difficulty level means smaller circles, but still in the same size proportion to each other based on populations.

hugequiz Premium members will see the 25 largest missed cities at the end of the quiz as large, purple markers.

There is also the option to play a 3-hour (basically untimed) version of each level. Simply enter a 'u' before a level choice to play a 3-hour version, for example 'ubeg' or 'uadv' - your score will not be saved for these.

World Bordering Countries Minimum Population Challenge – 25 Countries

The object of this game is to click on successive bordering countries to 'travel' through up to 25 countries with the objective of accumulating the smallest total population among all countries traveled through. Borders are land borders only, including causeways but not including only man-made structures. Borders include dependent territory borders, populations also include territories. Population in millions is shown. You must complete 25 countries for your score to save - so for example you can't get 'stuck' somewhere like South Korea with no other countries available to click on unless it happens to be your 25th country clicked.

For example, you can begin by clicking Russia - your next country can be any country bordering Russia, such as Ukraine. After clicking Ukraine you can choose any country bordering Ukraine except a country you have already visited (in this case just Russia). You must continue along your path and can't click a bordering country from a previously-clicked country unless it borders the country you just clicked.

World Circle Max Population Challenge

Upon clicking START you will be shown 4 circles, one at a time, with increasing radii: 500, 1000, 2500, and 5000 km. The object is to move the circle to the location such that it covers the most amount of people, based on World 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).

World Country Pairs Similar Population Blackout

Upon clicking START you will be presented with a 5×5 table of World countries. The object of the quiz is to pair up countries two at a time which have the closest ratio of their populations (including dependent territories).

Single click on a country’s text and it will highlight red. To choose the other country of the pair click another country’s text. Also, you can re-click on the first country to deselect it. The ratio of the larger country’s population to the smaller country’s will be shown and you will get up to 100 points. 100 points corresponds to the smallest population ratio, 0 points to the largest ratios (there may be multiple pairs with 0 if they are far away from the smallest ratio). Those two countries will then be replaced with their score and you will now choose the pair with the smallest population ratio from the remaining 23 countries which have been adjusted to have 100 and 0 corresponding to the ratios among those 23, and so on until you run out of time or complete 12 pairs of countries leaving one left.

You get a 100 point bonus for completing all 12 pairs within 5 minutes, making for a total possible point total of 2500.
