  • Each round names a measure and the date of its figures. Click the one with the highest figure among those still standing; it leaves the board.
  • No round is a coin toss: the leader is always more than 5 percent clear of the runner up.
  • The figures of the last round are shown under the buttons. Keys: type a name to jump to its button, Enter to pick.
  • Pause whenever you like (Esc). The board hides while the clock is stopped.

Click the country with the highest figure for the round. The buttons and the first round appear when you start.

About this quiz

6 games take turns, each with twelve countries and eleven rounds. Ribbia counts 197 countries: the 193 members of the United Nations plus Vatican City, Palestine, Kosovo and Taiwan. Every figure is shown once its round is over.

  • A round is only asked when the leader is clear: more than five percent ahead of the runner up for a size, and at least one ahead for a count.
  • Areas are surface area for 2023 and populations are United Nations estimates for mid 2025. Coastlines, land borders and highest points are 2025 figures.
  • Letters are counted without spaces, hyphens or apostrophes.
  • A wrong pick still removes the true leader, so the next round is the same for everyone.
