The cities quizzes are developed and operated by Ian Fisher. The first quiz, How many US cities can you name?, was published on my personal site in September 2019, followed by a cities of Europe quiz the next month. Over the following year, as the site gained traction I kept up a steady pace of new quizzes, culminating in a comprehensive cities of the world quiz in December 2020. In October 2022, I moved the quizzes from my personal site to the cityquiz.io domain, and added the ability to create user accounts.
You can view the history of updates to the site's database and functionality on the updates page.
Almost anything! Not just proper cities, but towns, villages, and hamlets, too.
No. You will only lose your progress if you clear the site data in your browser. If you create an account, you can save in-progress quizzes, too.
Yes. Once you save your quiz, the new URL can be sent to whomever you'd like.
Yes, as long as you've created an account. Simply copy the URL of the quiz page to your other device (you'll have to be logged in there, too).
First, double-check you've spelled the city's name correctly. Try variant spellings, if there are any. Next, make sure it is an independent settlement and not part of another municipality. If it is indeed, then it is probably just missing from the database.
The quality of the site's database varies by country. Some countries, like the United States and Brazil, have excellent data. Others, like China and most of Africa, have much sparser data.
Due to technical limitations, a city can only be in a single quiz, so I chose to put Istanbul in Europe instead of Asia.
Click the dropdown to the right of the input box and select 'Every country' or 'Every state'.

Most cities are accepted under both their common English name and their native name, e.g. Cologne and Köln. In countries that use the Cyrillic script, you can enter city names in Cyrillic. Large cities, especially in Europe, may be listed under their names in several languages. For example, 'Londres' is accepted for London.
A city's population is for the city proper whenever possible, rather than its urban area or metropolitan area. This is the only way to include every city without double-counting population. For some cities whose urban area is significantly smaller than the city proper (notably, many prefecture-level cities in China), I use the population figure for the urban component of the city proper instead.
You cannot save a game with more than 5,000 cities (7,500 for the world quiz). However, if you are not logged in, you can continue adding cities to your map; you just won't be able to save your results permanently. At around 22,000 cities, you will reach the limit for local storage in your browser. If you use Firefox, you can follow these instructions to increase the limit. If you use another browser, unfortunately there is no way around the limit.
Some cities were added to the database later, so their rarity scores would be artificially low because earlier players of the quiz did not have the opportunity to name them. These cities are excluded from the rarest cities list.
The cities quizzes were created by Ian Fisher and were originally hosted on his personal website.

Please understand that I am a single person and it is not always possible for me to respond to every email. I will generally ignore emails about a single missing city or incorrect population as there are simply far too many of them for me to individually address.
