Achilles — how good is your memory, really?

• 👀Study the diorama. Drag to orbit and look around — memorize each object's position and color before time runs out.
• 🫥Your view then gets wiped and shown again — but one thing may have changed color, moved, or vanished. Sometimes nothing changed at all.
• 👆Tap the object you think changed, or press Nothing Changed if the diorama looks identical.
• 🤔Then rate how sure you are: Certain, Fairly sure, or Guessing.
• 🧠6 rounds, less study time each round. At the end you'll learn your personal Achilles heel — the exact way your memory fools you.
