How do I play this quiz?

Take the World 1M+ Agglo Coverage Quiz and test your knowledge of the largest agglomerations around the world. Can you name the main cities within different radius levels?

Do abbreviations or alternate spellings count?

Yes. Most quizzes allow common abbreviations, alternate spellings, and short forms. Try typing just the first few letters — if it matches, it will autofill.

World 1M+ Agglo Coverage

First enter a difficulty level by typing 'beg', 'int', 'adv' or 'exp'. Beginner is 500km, intermediate is 250km, advanced is 150km and expert is 100km. Every 1M+ pop agglomeration within that radius will fill in. I tried to include a few cities that may not be the main city of the agglo, but try to name the agglo's largest/main city.

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.

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 50 1M+ Agglomerations Identifier

You will be shown a map with red markers for all 1M+ world agglomerations. Double-click on the one specified to answer it. If you click on the correct agglo, the marker will turn green. Otherwise no change will be made to the markers. 50 randomly chosen agglos will be given. A handful of agglos have the same name as another agglo in a different country - for these the country will be specified.

Note - you may want to zoom in if agglos are close to one another to make sure you are clicking on the correct one.

If the red markers do not appear when the quiz is loaded, try refreshing the page.

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.
