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 100 Km Expanding Circles Any City Challenge – Choose City

First choose any World 50K+ city by entering it and choosing it in the drop-down box. Then, name ANY World 50K+ city in each 100km circle/ring as the rings expand outward from your city of choice. The first circle will include your city of choice as a possible answer.

When you run out of time or end the quiz, you will see the current ring's largest correct answer at right (under 'Answer Stats' by your coordinates).

For example, if you choose 'Paris, France' - you will be shown a circle of radius 100km centered at Paris. Naming any 50K+ city in this circle (including Paris) will cause another 'ring' of radius 100km to appear outside that circle. You now need to name the any World 50K+ city in that ring (but not within any previous circles/rings). If a city is not within the next ring of that distance, the ring will keep expanding by that distance until a city falls within it. So if a city doesn't fall within 200-300km, it will expand to be a 200-400km ring, then 200-500km and so on until a qualifying city is found within the ring.

World 100 Km Expanding Circles Any City Distance Challenge – Choose City

First choose any World 50K+ city by entering it and choosing it in the drop-down box. Then, name any World 50K+ city in each 100 km circle/ring as the rings expand outward from your city of choice - NOTE - you must enter a period '.' at the end of the city to submit it. The first circle will include your city of choice as guessed. The object in this quiz is to guess the city in the next ring which is as close to the previous city as possible. The closest city will get you 100 points, the farthest away answer, 0 points.

When you run out of time or end the quiz, you will see the current ring's closest correct answer at right.

For example, if you choose ‘Paris, France’ – you will be shown a circle of radius 100 km centered at Paris and Paris will be selected. You will also see a ring of radius 100 km outside that circle. Naming a city in this ring will cause another ‘ring’ of radius 100 km to appear outside that ring and you will get 0-100 points, depending how close to Paris your city was. If a city is not within the next ring of that distance, the ring will keep expanding by that distance until a city falls within it. So if a city doesn’t fall within 100-200 kms, it will expand to be a 100-300 km ring, then 100-400 km and so on until a qualifying city is found within the ring.

World 100 Km Expanding Circles Small City Challenge – Choose City

First choose any World 50K+ pop city by entering it and choosing it in the drop-down box. Then, name any World 50K+ city in each 100 km circle/ring as the rings expand outward from your city of choice, trying to name SMALLER cities instead of the easier, larger cities. The first circle will include your city of choice as a possible answer.

PLEASE NOTE - You must type a '.' (period) after each city to submit it to prevent answering another city with a name you would be have to type to get your answer. If multiple cities have the name you submitted, only the smallest one will be counted.

You accumulate points based on the population of the city you named according to the following scale:
50K - 99,999 - 10 pts
100K - 149,999 - 8 pts
150K - 249,999 - 6 pts
250K - 499,999 - 4 pts
500K - 749,999 - 3 pts
750K - 999,999 - 2 pts
1M+ - 1 pt

When you run out of time or end the quiz, you will see the current ring’s smallest correct answer at right (under ‘Answer Stats’ by your coordinates).

For example, if you choose ‘Paris’ – you will be shown a circle of radius 100 km centered at Paris. Naming any city in this circle (including Paris) will cause another ‘ring’ of radius 100 km to appear outside that circle, however - you will want to try naming the SMALLEST city you can to get more points (Paris will only yield 1 point). After completing that circle, you now need to name any 50K+ World city in the new ring (but not within any previous circles/rings), again trying to name as small a city as possible. If a city is not within the next ring of that distance, the ring will keep expanding by that distance until a city falls within it. So if a city doesn’t fall within 100-200 km, it will expand to be a 100-300 km ring, then 300-400 km and so on until a qualifying city is found within the ring.

World 50K+ City Name Link Challenge

The object of this quiz is to pick a city to start, then name successive cities such that the next city's first letter is the last letter of the current city and the next city is as close to the current city as possible. On this quiz alternates are generally accepted, however only the main (usually official) name is counted as it relates to naming the next city. Cities of the same name will answer the closest city first. NOTE: You must type a '.' (period) after the city to submit it. Cities must be a minimum of 50k population. The same city cannot be used twice in this quiz.

For example, you start with 'Paris' - you are now trying to name a city starting with 'S' (the last letter of 'Paris') which is closest to Paris. If you answer 'Strasbourg' - now you are trying to name the closest city to Strasbourg which starts with a 'G' and so on.

The quiz ends at the 25th city from the starting one. You get 100 points for naming the closest city on each step, and they decline based on the distance your city was from the closest. You get 15 minutes to complete the quiz.

World 50K+ City Shrinking Coverage Challenge

You begin with a radius of 1500km. Enter World 50K+ city names and all 50K+ World cities within that radius will fill in, HOWEVER each time you use a circle the radius will shrink by 5%. Try to cover as many cities as possible as the circles get smaller. Time is not part of the score on this quiz.

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

Notes for this quiz: answering a city that has the same name in multiple locations will reduce the circle 5% in radius for each unique city that matches, so if you enter 'Brest' - it will fill one of the 2 with whatever radius you are at, then shrink it 5% and fill the other, and again shrink it 5% more until you make your next guess. So it may not be wise to use a common city name. Also, to enter a city such as 'Mexico City' without entering 'Mexico' (a city in Philippines) you can simply type for example "xmexicocity" then delete the x, thereby preventing you from typing 'mexico' - there are a handful of cities like this.

World 50K+ Closest Cities To Your Location In Order – Choose Number

Begin by entering a number of cities - '50', '100', '250' or '5h' - then name the closest world cities of 50K+ population to your geographic location (as determined by your browser's location function) IN ORDER - meaning you have to name the closest first, then the 2nd closest, etc. Your location will show up as a bright purple marker, and the location you need to name (the closest unnamed one) will show up as a larger marker color-coded according to its population.

To use this quiz you will have to choose 'Allow' if your browser asks to share your current location - you also may have to restart the quiz after choosing this. If your browser does not allow getting your location the quiz will not load.

528

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 Coverage

First choose a level by typing 'beg', 'int', 'adv' or 'exp' - beginner is 50,000,000, intermediate is 10,000,000, advanced is 5,000,000 and expert 1,000,000. Then, begin naming cities. All cities of 50K+ population starting with the city you chose and moving outward will begin filling in until you've hit a total population equal to or greater than your chosen level's threshold. For example, if you choose 'int' - the threshold is 10 million. If you choose 'paris', then Paris will fill in and because its population is under 10 million, successive cities moving outward from Paris will fill in until the total population reaches at least 10 million. If you chose Tokyo, only it would fill in as its population already meets your threshold.

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

Premium members can now also play a 3-hour time limit 'custom' coverage quiz of any population from 500,000 to 100,000,000, simply enter the population followed by a '.' instead of choosing from one of the four levels, i.e. '750000.' Quiz score is not recorded for the custom coverage option.

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.

NUMBER RANGE: (such as 2-5, 10+) means the city contains that many letters (excluding spaces and special characters).
POPULATION RANGE: (such as 50-100K) means the city has that range for its population.
2+ WORDS means the city name has 2 or more words (words denoted by a space or hyphen).

At the end of the quiz the largest population missed answer will show in each unanswered square, and for those answered the largest city will be listed if you didn't answer it.

World Grid Path Challenge – All Cities

Choose a level by typing ‘beg’, ‘int’, ‘adv’, or ‘exp’ – beg level is 15 degree squares, int 10 degrees, adv 5 degree, and exp 2.5 degrees. Then, name any 50K+ World city to start with by entering it (cities with the same name will choose the largest city of that name first). The grid square you are starting in will turn yellow - you now must name any city in any one of the adjacent grid squares (not including diagonal) - so any grid square directly north, south, east or west of the yellow one. Naming a city in one of these squares will turn your original square red and the current newly named city square yellow - continue in the same way trying to make a path of as many squares as you can. You are not allowed to return to a red square, and if you get 'boxed in' with no squares left to complete the quiz will also end.

Be aware that as you name cities it will answer the largest city first, so if you are trying to answer a city in a square to the east but a larger city of that name occurs a square to the north, the north one will be answered.

PLEASE NOTE: You get TWO separate 'paths' to create - one within the Americas and one within Europe/Africa/Asia/Oceania. You can start on either side and hop over to the other side whenever, in which case you will have 2 yellow squares to continue paths on.

Obviously, due to the layout and separation of squares it will be impossible to complete all of them.

World Grid Population Challenge

First choose a grid size by typing '30', '20', or '10'. A grid of that size lat/long will be placed on the map (so if you choose '20' the grid width and height will be 20 degrees). Then, double click on the grid square with the highest population within it (based on world 10km x 10km population density estimates). The highest-population remaining square will give you 100 points, all the way down to 0 for the one with the smallest population. Try to obtain the most points by successively double-clicking on the highest-populated grid square.

World Random Grid Path Challenge – All Cities

Choose a level by typing ‘beg’, ‘int’, ‘adv’, or ‘exp’ – beg level is 15 degree squares, int 10 degrees, adv 5 degree, and exp 2.5 degrees. A randomly placed grid of that size will then be placed on the map. Then, name any 50K+ World city to start with by entering it (cities with the same name will choose the largest city of that name first). The grid square you are starting in will turn yellow - you now must name any city in any one of the adjacent grid squares (not including diagonal) - so any grid square directly north, south, east or west of the yellow one. Naming a city in one of these squares will turn your original square red and the current newly named city square yellow - continue in the same way trying to make a path of as many squares as you can.
