Blog > Monthly Geo Trivia questions

Welcome to the March 2025 edition of #fridaygeotrivia, our social media geotrivia contest. We play on the final Friday of every month, the March 2025 edition will be played on Friday, March 28th, 2025, at 17:00 Berlin time, 4pm London time, noon New York time.

See how to play below.

The March 2025 geotrivia question:

We recently moved our company headquarters to Berlin, a city with the unique property of also being a German state (Bundesland). This month’s question - name countries that have “city states” (ie cities that have ISO 3166-2 codes like DE-BE for Berlin). Name the country and the city-state

As always:

  • Only one answer per toot

  • You must include the hashtag #fridaygeotrivia and the emoji flag of relevant countries

Prizes

#fridaygeotrivia is a game with two prizes:

  1. the sheer joy of geographic knowledge and pedantry.

  2. the bragging rights of getting the answer first.

How to play

Anyone can join in, you just need a Mastodon account.

  • Follow us on Mastodon, our account is @opencage@en.osm.town

  • When the game starts we will post the question here on the blog and on Mastodon, and will embed the Mastodon question here. We highly recommend using a mastodon client you feel comfortable with. We’ve made the switch to the Elk client and are loving it, but use whatever works for you.

  • Reply to the question thread on Mastodon (it will be embedded above) using the hashtag #fridaygeotrivia in your answer.

  • Only one answer per response (don’t stuff multiple answers into a single reply).

  • Our definition of “country” is usually (it depends on the question) any place with an ISO 3166-1 alpha-2 code. Read more background about ISO and country codes in our guide.

  • To get full points for an answer it is good form not just to name the relevant country but (if possible) to include the emoji flags of the country.

  • While you can use a map, please do NOT use the internet to just search for an answer. That is cheating and will lead to seriously bad geokarma.

Some people have complained that the format is a bit chaotic and hard to follow. Yes. The mad chaos is part of the fun. Embrace it. The goal is just to have fun and learn. We win by playing

Thanks for playing,
