Less counting. More intuition.

Five rounds a day. The same little challenge for everyone.

  1. Take a lookAfter the objects settle, you have 15 seconds to look. Drag the scene to change your view.
  2. Make your guessEnter your guess before time runs out. It locks in automatically; empty rounds are skipped.
  3. See the answerThe closer you are, the more you score. Up to 100 points per round, 500 in total.

Only objects inside the glass count.

In Compare, choose the fuller side and estimate the difference. The wrong side scores zero. The timer continues in the background. New puzzles at 00:00 UTC.
