Name the world's biggest cities seven ways: A to Z, by continent, region or country, the top 3 per country, and the biggest cities that aren't capitals.
Typing quizzes on the world's cities: the biggest by continent, region or country, A to Z by first letter, the top three in every country, and the countries whose biggest city isn't the capital. Populations come from national statistics offices and the UN, and the credits page lists every source. If you've done a city quiz on Sporcle or JetPunk, it's the same format.

How it works
1Type the cities in any order. A name is credited the instant it's valid, with no need to press Enter, and common alternate names and spellings work too.
2Score is how many you name before the clock runs out. Name every one and the board also tracks the time you finished in.
3Stuck? Hint points you toward the biggest city still missing, but costs 15 seconds. Tap ↓ on one you don't recognize to sink it to the bottom of the list.
Tips
Start with the biggest cities. They're the easiest to recall and get you going.
Think regionally. Go through a country's regions one at a time and name the main city of each.
Sink the ones you don't know. Tap ↓ on a city you've never heard of so the list shows what's left.
Questions
Where do the populations come from?
GeoNames, which mostly draws on national censuses and statistics offices, and the UN's World Urbanization Prospects. Countries count cities differently, some by the city proper and some by the urban area, and the credits page lists every source.
Do I need accents?
No. Names are accepted without accents, and common alternate names work too.
Which quizzes are there?
The biggest cities by continent, region and country, cities A to Z by first letter, the top three in every country, and the countries whose biggest city isn't the capital. Some longer tiers are for supporters.
Which city quiz to start with
There are 6 continent quizzes, 24 regional ones like the Middle East and the Caucasus, 142 for countries and 228 for states and provinces, plus 26 A to Z quizzes by first letter and 6 of the top three cities in every country.
Continents are the place to start: their biggest cities are the world's best known. Countries and states test deeper knowledge, and the A to Z quizzes mix the whole world together, which makes them some of the hardest.
