Why a log scale

Magnitudle asks for one real number, like a distance or a population, and you place your guess on a logarithmic scale. On that scale each step is ten times bigger than the last. Guessing 2,000 when the answer is 1,000 is close. Guessing 10,000 is a full step off. It rewards getting the size right, not the exact digits.

Anchors that help

  • The world has about 8 billion people.
  • Around the Earth is about 40,000 km.
  • The Moon is roughly 384,000 km away.
  • A large city has millions of people, a small town thousands.

Size It Up and Pop Culture

The same site has Size It Up, where you resize one object next to another, and a Pop Culture game. All are free in the browser and the app. If a game is not loading, it is usually the site being busy, so try again a little later.

Before you start Magnitudle

  • Think in powers of ten first: is it hundreds, thousands or millions?
  • Compare with something you know, like a city's population.
  • Keep your streak by playing every day.
