About Flagdle

Flagdle is a daily geography guessing game inspired by Wordle. Every day, a new flag is hidden behind 9 tiles that reveal themselves with each guess: identify the country in 3 attempts. The game covers the 195 countries recognised by the UN and runs entirely in your browser.

Not to be confused with Flagle (no D): Flagdle is an independent project with its own 9-tile reveal mechanic in 3 tries, and offers six distinct game modes (flags, capitals, hints, Worldle, daily challenge, themed quizzes).

Our mission

Make learning geography fun and accessible. A game only takes a few minutes, the daily flag is the same for every player worldwide, and the different modes let you test various aspects of your knowledge: flags, capitals, clues, distance, daily challenge and themed quizzes.

Game modes

• Flags — guess the country in 3 tries; the flag reveals itself with each attempt.
• Capitals — find the capital of a given country.
• Hints — guess the country from progressive clues.
• Worldle — distance, direction and continent.
• Daily Challenge — one challenge a day with 6 mini-games to learn about a country.
• Quiz — 10 themed questions per day.

Data sources

Flag images are served by FlagCDN (ISO 3166-1 codes). Country names, capitals and continents are embedded directly in the codebase in both French and English.

Privacy

Flagdle requires no account. Your stats are stored only in your browser (localStorage), no personal data is sent to a server. Anonymous analytics tools (Vercel Analytics, Mixpanel) measure aggregate usage to improve the game.

Technologies

Flagdle is built with Next.js 16 (App Router), React 19, strict TypeScript and Tailwind CSS 4. The site is hosted on Vercel and the code runs entirely client-side — no backend, no database.
