Area Guesser

Three seconds with the shape and its cm² — then four unlabeled shapes. Pick the one that matches; cm² for all four appear only after you tap.

How to Play

  • 1 Each round starts with one filled shape in the center; its area in cm² appears on top (same px→cm rule as Match the Area).
  • 2 You have about three seconds to study it — there is an on-screen countdown.
  • 3 The shape disappears and four different shapes appear in a two-by-two grid. Exactly one has the same area — no cm² on the grid until you tap.
  • 4 After you tap, each quadrant shows its cm² so you can see how close you were. Distractors stay within a few percent.
  • 5 Tap the quadrant you think matches. Green outlines mark the correct answer; your choice is outlined red if it was wrong.
  • 6 Use Next round for another puzzle. Your streak counts consecutive correct guesses.
