How to play

Two pictures, six differences, one timer. Everything runs in your browser — there is nothing to install and no account to make.

The emblem: a magnifying glass held over a street, with one figure in red inside the lens.

  1. Compare the two images and tap a spot that looks different. Either image works.

  2. A correct spot is circled on both images at once.

  3. A wrong tap adds five seconds and locks input for a moment, so guessing is slower than looking.

  4. Find all six to finish. Your time and your penalty are shown separately.

Questions

When does a new puzzle appear?
At midnight in your own time zone. The site uses your device's calendar date, so the puzzle changes when your date changes.
What does the penalty do?
Every wrong tap adds five seconds to your total and briefly locks the images. Your raw time and the penalty are always shown separately, so you can see which one cost you.
Do old puzzles count?
No. Archive rounds are practice only. They never change your streak or your statistics.
Is my progress saved?
It is saved in your own browser, so it stays on this device. Clearing site data clears your streak, and there is no way for us to restore it.
