FAQ
- How is the score counted?
- You earn points for each difference you find. Faster finds and fuller scenes score higher.
- Do I look at both scenes at once?
- You toggle between them. Flip back and forth to catch what moved, vanished, or changed color.
- What if I tap the wrong spot?
- Wrong taps cost time or points depending on the round. Keep scanning for real changes.
- Is this a vision exam?
- No. It is a puzzle game, not an eye test or medical screening.
