Plain

How to play

7 targets · ~3 minutes · daily

Choose an answer whose value feels closest to the target.

You do not need an exact fact. A good estimate is what counts.

See the real values after each round, compare with friends, and return tomorrow.

Plain

Mountains, movies, meals and more. Build a better sense of scale, one guess at a time.

Compare mountains, buildings, bridges and rivers.

Think film grosses, running times, food energy and burger prices.

Explore populations, animal lifespans and Pokémon sizes.

Plain

A small daily ritual — Plain rewards a feel for magnitude rather than perfect recall. Everyone gets the same daily puzzle, with no endless feed.
