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 Challenge – Choose City

First choose any World 50K+ city by entering it and choosing it in the drop-down box. Then, name the largest 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 if it is the largest 50K+ city in that area.

When you run out of time or end the quiz, you will see the current ring's 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 the largest city in this circle (Paris in this case) will cause another 'ring' of radius 100km to appear outside that circle. You now need to name the largest 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 Largest 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 LARGEST city in each circle. 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 largest one will be counted.

You accumulate points based on the population of the city you named in relation to the largest city in the circle. Naming the largest city will get you 100 points. A smaller city’s point total will be the ratio of its population to the largest, so if you name a city of 75K people and the largest city has 100K, you get 75 points.

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’ – 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 LARGEST city you can to get more points (Paris will be 100 points). 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 large 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 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 1M City Coverage Challenge

Enter a World 1M+ city - all other 1M+ cities within 1000km will also fill in. Try to fill in all 1M cities in the smallest number of circles. Countries remaining will display when you have completed 80 countries. For Khartoum, enter 'khartoum.' with the period to prevent entering Khartoum North. For Hyderabad, there are two, so enter 'hyderabadin' for India and 'hyderabadpa' for Pakistan. Also there are 2 'Taizhou' cities in China. To name the southernmost (slightly larger) one, type 'taizhou1' - for the other type 'taizhou2'.

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

World 1M+ Agglomerations Name Link Challenge

The object of this quiz is to pick a world 1M+ agglomeration to start, then name successive 1M+ agglomerations such that the next agglo's first letter is the last letter of the current agglo and the next agglo is as close to the current agglo 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 agglo. Agglomerations of the same name will answer the closest one first. NOTE: You must type a '.' (period) after the agglo name to submit it. The same agglo 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 'Sevilla' - now you are trying to name the closest 1M+ agglo to Sevilla which starts with a 'A' and so on.

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

416

World 1M+ Agglos Direction Challenge

The object of this quiz is to name (see NAMING NOTE below) as many World 1M+ agglomerations as possible starting from the position you choose without skipping agglos moving in the opposite direction. For example, if you choose 'S' you 'start' at the South Pole to begin and you are aiming to name the most southern World 1M+ agglo, then the 2nd most southern, and so on as you move north. Naming correct agglos increases the population counter - the object is to get the highest total population among all agglos you name. However, once you move in a direction you can't name agglos already passed by (i.e. covered in the blue shaded region).

NAMING NOTE: You must end each agglo name with a period - i.e. 'Tokyo.' - this prevents naming an agglo whose name is a partial name of the agglo you want to answer. If you name an agglo that has multiple answers, only the closest upcoming one will be answered for you, so you won't name the farther away agglo from the one you are trying to guess.

You don't start with a ton of time, however there is a 30 second time bonus for naming the next agglo in order, and a 15 second bonus for naming the 2nd or 3rd next one in order. So if you name well you can accumulate a lot of extra time.

hugequiz Premium members will see up to the largest 25 agglos missed when the quiz ends - they will be pink markers you can mouseover to see agglo details.

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 200 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 200 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 200 km centered at Paris and Paris will be selected. You will also see a ring of radius 200 km outside that circle. Naming a city in this ring will cause another ‘ring’ of radius 200 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 200-400 kms, it will expand to be a 200-600 km ring, then 200-800 km and so on until a qualifying city is found within the ring.

World 200 Km Expanding Circles Top 3 Challenge – Choose City

First choose any World 50K+ city by entering it and choosing it in the drop-down box. Then, name the top 3 largest World 50K+ cities in each 200km 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 if it is in the top 3 largest 50K+ city in that area. As you enter cities you will see their rank within the current ring (1st, 2nd or 3rd largest) above their marker.

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 200km centered at Paris. Naming the 3 largest cities in this circle (such as Paris) will cause them to appear as green markers and when all 3 are named another 'ring' of radius 200km to appear outside that circle. You now need to name the 3 largest World 50K+ cities in that ring (but not within any previous circles/rings). If no city qualifies within the next ring of that distance, the ring will keep expanding by that distance until at least one city falls within it. So if a city doesn't fall within 200-400km, it will expand to be a 200-600km ring, then 200-800km and so on until at least one qualifying city is found within the ring.

The first circle will include your city of choice as a possible answer if it is in the top 5 largest 50K+ city in that area. As you enter cities you will see their rank within the current ring (1st, 2nd, 3th, 4th or 5th largest) above their marker.

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 200km centered at Paris. Naming the 5 largest cities in this circle (such as Paris) will cause them to appear as green markers and when all 5 are named another 'ring' of radius 200km to appear outside that circle. You now need to name the 5 largest World 50K+ cities in that ring (but not within any previous circles/rings). If no city qualifies within the next ring of that distance, the ring will keep expanding by that distance until at least one city falls within it. So if a city doesn't fall within 200-400km, it will expand to be a 200-600km ring, then 200-800km and so on until at least one qualifying city is found within the ring.

World 500 Km 50-Circle Coverage Challenge

You start with a blank map. Double-click on the map to create a circle of 500km radius centered on that location. All World 50K+ cities within that circle will appear and count toward your total cities. The object is to cover as many cities as possible in 50 circles. You can click within an already-created circle as well, however you may have to zoom in slightly so you aren't clicking on an existing city marker.

World 500 Km Coverage Challenge

Choose any 50K+ World city, then continue naming 50K+ cities which are within 500 km of any previously named city. Please note - North/South America and the rest of the world are considered separate sections on this quiz. The game will not end if you haven't begun one of them and then 'jump' over to it to begin working on it. So you get one free city to choose outside of the 500km distance if you want to start working on the section you haven't started. But once you have started both NA/SA and Rest of World, you cannot guess a city outside a 500km circle or the quiz will end.

Naming notes: many places have similar names. For example, “Brest” is not unique. To choose Brest, France, simply type “brestfr”, using the first two letters of the country name...another example is "londonun". Also, some answers require typing in other answers you may not want to guess. In this case, if you want to answer “Hamburg”, simply type it..”Ham, Belgium” will not be chosen. If you want simply “Ham” type ‘ham.’ with the period at the end. One other issue is multiple cities in the US with the same name, for these type in the state abbreviation and 'us' at the end - i.e. 'jacksonvilleflus' - if a place name outside the US has multiple locations in a country you can use 'fuzhouch1', 'fuzhouch2' etc for the Fuzhou's in China.

World 500K+ Cities Locator Timed Challenge

The object of this quiz is to click on 500K+ city locations as quickly and accurately as you can. You get 25 random World cities from among all World 250K+ cities. You will be scored based on Time, Distance, and Closest Cities. Closest Cities refers to how many cities (among ALL 50K+ cities, not just 500K+ ones) are located closer to the actual city's location than where you clicked. Upon clicking START you will see cities listed one at a time in the upper right on the side of the map. Double-click where that city is as fast and accurately as possible. You will then get a score of 0-100 based on those 3 factors. Also, up to 10 of the closest cities to the target city that you weren't within will be displayed. Click NEXT CITY to continue on.

To make things easier, you will get at most 2 cities from each country each time you play.

NOTE – For cities with the same name, you are trying to click on the LARGEST city of that name.

For Premium members, this quiz is much easier to play on Google Maps full screen mode.

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+ 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 Capitals Triplets Blackout Challenge

Upon clicking START you will be presented with a 5×5 grid of 25 of the capital cities of World countries.

The object of this quiz is to choose the top 3 in the given category for the capitals shown in the grid. When you begin you’ll be given 25 different capitals plus a category to name the top 3 in, which will display just above the grid. For example, if the category says ‘Top 3 Largest Population’ you are to click on the 3 capitals with the largest population. If it says ‘Top 3 Lowest Population Density’ you are to click on the 3 whose population density is the lowest. You can deselect the first or second capital you chose on by re-clicking it, but when you choose the 3rd capital they will be submitted, removed from the grid, and you will get a score from 0-100 based on how close your set of 3 comes to the optimum set of 3 (which will be shown as a ‘Rank’ on top out of the # of possible sets of 3 for the last choice). When you’ve answered all 8 sets of 3 leaving only 1 capital the quiz is over. You get a 100 points bonus for completing the sets making for a total possible score of 2500.

World Cities Grid Identifier Challenge

The object of this quiz is to double-click the grid square where cities are located (the centroid of the city is used). When you begin you will have a grid randomly placed with size 15 degrees latitude by 15 degrees longitude. You will be told which city to locate – simply double-click on that city’s grid square and you will move on to the next city. Each time you go to a new city the squares are randomly redrawn and with a size 10% smaller. The first 10 cities will be 5M+, the next 10 2.5-5M, next 10 1-2.5M and the balance (until you run out of time or guess wrong) will be 500K-1M. When you guess wrong the correct location will be shown as a pink marker.

You will not get more than one city per country in the first 3 groupings of 10, however for the final balance (when the cities are 500K-1M) there is no limit to how many cities in one country you will get.

You do get a break if you are within 2 km of the city but in the wrong square – you will not get credit for the guess but will get another chance at that level.

After the quiz is over you can click RESTART to retry it without refreshing the page.

If you are under the max distance allowed you will move on to the next city. When you double-click farther away than the max distance allowed the quiz will end.

PLEASE NOTE - To identify a city, click on the 'downtown' area to avoid clicking on a suburb or outer edge of the city. The distance will generally be measured from close to the center of a city's 'downtown.'

You begin with 10 minutes (or 5 for non-Premium members) and get 10 seconds added every time you double-click to locate a city.

World Expanding Circles Challenge – Your Location

First choose a level by typing '50.', '100', '250' or '500' - (need the period after '50' so 500 can be typed) then name the largest World 50K+ city in the circle/ring of that distance range (in km) as the rings expand outward from your location. You need to have your browser's location function working or the quiz will not load.

You MUST have a city within the initial distance you choose for your level - so this quiz will not work if you are not within a 50K+ city at the distance you chose to begin with.

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

For example, if you choose '250' - you will be shown a circle of radius 250 km centered at your location. Naming the largest city in this circle will cause another 'ring' of radius 250 km to appear outside that circle. You now need to name the largest 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 250-500 km (assuming your level is 250 km), it will expand to be a 250-750 km ring, then 250-1000 km and so on until a city is found within the ring.

World Google Street View Country Streak Challenge

You will be presented with a random google street view image in a locality somewhere in the world where google street view has coverage.

You can then type 'start' to restart the quiz.

Please note - this quiz is only available to hugequiz Premium members, as it costs money for me to use the street view API and this quiz is more costly than the other street view ones.

World Great Circle 3 Strikes Daily Challenge

Click START to begin. You will be shown a route between 2 world capital cities and the starting country will be shown as the upper left cell in the grid. No route will have less than 5 total countries. A new route will appear each day at midnight central US time.

Starting with the 2nd country (the first country is always your departure country), name the countries (see NAMING NOTE below) in order whose land territory (including dependent territories) you fly over to your destination. Capital routes are from the city centers NOT the airports. You are answering based on when you FIRST fly over them (occasionally you may fly over a country, then another, then the previous country again, do NOT list the first country twice). Each country is only answered once. The last country is generally the destination country, but not always (as you may have crossed over it previously then another country, then back over it to arrive).

You get 3 strikes before the quiz is over. Each wrong country guess is a strike.

NAMING NOTE - Most disputed territories are considered to be part of the country that administers them (such as Western Sahara as part of Morocco), unless there is joint administration in which case the territory is not counted as any country. To answer countries like 'Guinea' or 'Niger' put a '.' (period at the end) as they must be typed to enter another country, similar 'UK.' (with the period) can be typed for United Kingdom, as it must be typed to enter Ukraine.

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.

hugequiz Premium members will see the largest missed city in each possible next square at the end of the quiz as purple markers.

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 Grid Top 5 Challenge

Type 'easy' or 'hard' to begin the quiz. Easy is a 15-degree grid, hard is a 10-degree grid. Then, try to name the largest 50K+ cities in each square IN ORDER. To name a city, you must first click on the grid square to make it have a GREEN border. Then, type in the city answer for that square followed by a '.' (a period).

The squares will start with '0/5' (or maybe fewer cities if less exist in that square). Click on a square and enter the largest city in that square not yet answered (so, the largest city if you have yet to answer a city in that square). You will then have '1/5' and need to click on that square to name the 2nd largest city, and so on until you complete all the cities up to 5 (or less if less exist). If you name an incorrect city in a square it becomes 'locked' and turns red and you can no longer accumulate cities in that square.

You receive 1 point for the largest city in a square, 2 for the 2nd largest, and so on.

At the end of the quiz the largest remaining city you haven't named will be shown in each square.

Double-click the country to 'lock' it in place and you will obtain a score up to 100 based on how close the center of the country is to the actual center coordinates. Four small European countries begin placed in the Mediterranean between Spain and Italy (right above the white rectangle).

You can end the quiz at any time or double-click on all 44 countries to place them to end the quiz as well. There may be a couple instances of a country with portions that are disjointed (Azerbaijan for instance) - only the larger portion of the country is shown in this quiz.
