Four things, one correct order. Biggest, tallest, longest, oldest — it depends on the round. Tap two items to swap them.
6 kinds of round · endless
Each round gives you four things and asks you to arrange them — countries by population, mountains by height, rivers by length, films by release date. Tap one item and then tap another to swap the two, then lock in your order. Every item has to be in the right place; close does not count.
Rounds are built so the four values are clearly different from one another, so it is a test of what you know rather than a coin flip between two near-identical numbers. You have three lives, and after every round you see the real figures — so a wrong answer still teaches you something.

Populations, heights, lengths and release dates come from Wikidata, which is free and open. Rounds are assembled so the four items are clearly different in size, rather than being a coin flip between two near-identical values.
