Two countries, one number. Tap the one that's higher. Ten a day, from worlds apart to neck and neck.

Round 1 of 10

Numbers: Our World in Data (CC BY 4.0), from the UN's World Population Prospects, the World Bank, the Global Carbon Budget and the ITU. Every answer names its source and links to the chart. The 160 countries with a million people or more; each number is for one year, the same year for every country. Higher only means higher, not better. A new ten every day at your midnight; everyone gets the same ten. Add ?day=2026-10-26 to the address to play any earlier day. Nothing leaves your browser. New: Mercator Trap, two countries drawn the way web maps draw them; tap the one that is really bigger.
