About flags.games

I wanted a better flag game, so I made one.

flags.games is quite literally the best browser flag game to ever exist. Learn and test your knowledge of flags from around the world. Play Flag Quiz solo, host a live room with friends, complete today's Daily Flag, or try dedicated Flag Challenges like Blur, Connections, and Holes.

Why flags.games exists

flags.games was built to give players a fast, clean, and accurate flag game: true proportions, instant loading, and zero intrusive ads.

Data and coverage

Standard quiz rounds draw from a pool of 205 countries and territories, while Learn and Explorer cover all 242. Data is organized around ISO standards, official vexillological records, and regional geographic groupings.

Dependent territories (Hong Kong, Bermuda, Puerto Rico) are not included in Daily and multiplayer so the shared puzzle stays fair. You can add them on Solo Hard from the difficulty picker on /play.

How flags.games pays its bills

Right now, flags.games makes zero money. It is an independent project self-funded out of pocket. Hosting stateful WebSocket multiplayer servers, reactive databases, and delivering millions of flag images worldwide is completely free for players.

If the game grows and server bills increase in the future, we plan to explore sustainable ways to cover hosting—such as optional Supporter perks, display banners, or standard HTML5 game ads. Whatever we introduce, we commit to three core standards:

  • No mid-game interruptions: ads will never pop up or shift layouts while you are actively answering a question.
  • Privacy-first: anonymous analytics only. We will never sell your personal data to brokers or advertisers.
  • Free core gameplay: Solo, Daily, and Multiplayer will always remain free to play.

Who runs it

flags.games is independently created and maintained. We build software we enjoy using ourselves. Mail goes to support@flags.games or /contact.

Security reports go to security@flags.games. The file is at /.well-known/security.txt.

Corrections

If a flag fact is wrong, write via /contact. We fix the record.

Do I need an account

You can play Solo, Daily, any challenges, Learn, Explorer, and multiplayer without signing in. An optional account (email, Google, or GitHub) keeps XP, friends, your daily streak, and stats across devices.

There's no paid API and no developer key. Public pages are open.
