How to play What Changed?

  1. Study the scene — a room, a park, an aquarium or a desk — until the eyes blink shut.
  2. When they open, something has changed: an object moved, vanished, appeared, changed colour or turned. Tap where it happened.
  3. A wrong tap costs a heart. Quick, perfect rounds build a streak multiplier. Later rounds hide 2–3 changes in busier scenes.
  4. Peek shows the original scene again; Hint marks one change. Upgrades add study time, hearts and power-ups.
