How to play

How Magnitudle works

Every round asks one question about size, in one of five ways.

  • Resize to real scaleDrag a silhouette until it is as big as it really is next to a reference.
  • Rank by sizePut three or four things in order, from biggest to smallest.
  • Pick the biggestTap the one that is really the biggest.
  • Estimate the numberType your best guess for a number.
  • How many fit?Guess how many of one thing, lined up end to end, match another.

Points, stars and which modes have a time limit are all explained in how the game works.
