Numbers worth remembering
Most of these are guessable if you carry a few anchors. Russia is about 17 million km², roughly twice the size of the next country; the United States, Canada and China are all around 9.5–10 million. India's population passed China's in 2023; both are around 1.4 billion. The Nile and the Amazon are both roughly 6,500–6,700 km, and the argument over which is longer is still open.
Heights are easier to place on a slider if you remember one rung on each ladder: Everest at 8,849 m, Kilimanjaro (Africa's highest) just under 6,000 m, Mont Blanc just under 5,000 m; the Burj Khalifa at 828 m, the Eiffel Tower at 330 m. Everything else sits somewhere between those.
The whole pack, timed, with streaks and a leaderboard, is in the app.
