About Geo Nerd

Geo Nerd tests what you actually know about the world's countries: their flag, their capital, their spot on the map. No fluff, no bloated quiz — just the question asked straight, with a clock that shows no mercy in the harder modes.

Free, ad-free, no sign-up required.

The six games

Each family has its own variants: multiple choice to learn, typed answers to check, a clock to make it hurt.

How it works

  • Playable without signing up

    Progress and best scores stay in your browser, even without creating an account.

  • An account to keep your progress

    Scores sync from one device to the next and join the global leaderboard, if that's your thing.

  • Free, with no ads

    No banners, no videos to sit through, no paid tier unlocking extra countries.

  • Two languages, one site

    Everything exists in English and French, including country and capital names.

Behind the scenes

Geo Nerd starts from the 193 UN member states, not one more or less: no territories, no dependencies, no unrecognised states, to keep the scope complete and identical from one game to the next.

The Daily Challenge draws the same questions for everyone from the date, a bit like Wordle, and when a flag changes in real life — Syria's did in late 2024 — it changes here too.

The site is built by one person, on their own time, with no studio or ad agency behind it. No framework, no account required: just enough code to make it work.
