Estimate the unimaginable

A daily game about orders of magnitude

How many trees are planted on Earth in a day? How heavy is the Great Pyramid? Magnitudle asks one question like this every day. You answer with a single number, and the game tells you how close you were on a logarithmic scale.

Being off by a factor of two barely costs you anything. Being off by a factor of a thousand does. That is the whole idea: you are not trying to know the answer, you are trying to land in the right order of magnitude.

Three ways to play

The Daily Question is the heart of the game: everyone gets the same question, you get one guess, and your streak grows each day you play.

Survival Mode is the fast version. You have 10 life and 15 seconds per question, and every answer costs you as much life as the orders of magnitude you missed by.

Size It Up is visual. You resize a silhouette until it matches its true size next to a reference you know, from a sheet of paper to a skyscraper, across three categories: everyday objects, pop culture and geography.

Why estimation is worth practicing

Physicist Enrico Fermi was famous for getting surprisingly good answers from almost no data, just by breaking a question into pieces he could reason about. The same skill helps you sanity check a headline, a budget or a business plan.

A few minutes a day is enough to feel the difference between a million and a billion, which is most of what numerical intuition is.
