Match countries and capitals across all UN member states, region by region; build a streak or share a local duel.
Useful to know
Which content does this game cover?
All 193 UN member states, grouped by region. Coverage is selective, not worldwide-complete.
How is local two-player play kept fair?
Where available, both players receive the same card, choices and deadline. Each response locks independently. Neither player sees answer feedback or updated points until both have responded or time has expired. There is no speed tie-break. This is a friendly shared-screen game; it cannot prevent watching another person’s physical taps.
Does the game upload or save my answers?
Pause and hidden-tab events stop active answer time and hide the board; Resume is explicit. Review time is excluded. Optional eligible solo summaries can enter device bests only after explicit opt-in; it starts off on every visit. Local duels, untimed practice and incomplete sessions are unranked. No names, accounts, remote multiplayer or server score submissions.
Can I check a source after answering?
Yes. The answer review links to the relevant primary or conservation-organisation source. The complete JSON and CSV review retain source URLs. The content edition is shown in the game.
Do I need to fill in the settings before I can play?
No. Quick play starts a complete built-in round with sensible defaults. Open Customise this game only when you want to change the available settings.
How does automatic continuation work in this game?
Choose an answer and read the feedback before the next card follows automatically. In a local duel, the reveal waits until both players have locked an answer or the shared timer expires. Use Stay on this answer or Pause when you need more time, or turn off automatic continuation in the game preferences. Continue now remains available.
Where are my files and inputs processed?
Play stays in this browser, with no account or remote leaderboard. Personal bests are saved only if you enable that option. Reset clears the round; use Erase device scores to remove those optional records from this browser. Private prompts and answers are excluded from the shared summary actions.
