Loses the round
  • 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 state 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 states and eleven rounds. All 50 states are in play. 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 total area, land and water. Populations are estimates for 1 July 2025. Bordering states share a stretch of land or river border; a state that meets another only at a point or across water is not asked about its neighbours.
  • 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.

Note on the data. Every figure is read from Ribbia's shared state data: Census Bureau total areas and resident population estimates for 1 July 2025, admission dates from the Congressional Research Service table, the National Archives list of state capitals, and neighbours from the Census Bureau county adjacency file, all read on 3 October 2026. People per square kilometre is the population divided by the total area. The sets are dealt by a fixed seed and a test recomputes the answer of every round from the shared data.
