Cross Your Eyes
1 / 24
How to see it
Make a third image appear in the middle
- Hold the screen at a comfortable distance.
- Gently cross your eyes until the two white guide dots become three.
- Relax your focus on the middle image, then answer the depth question.
Stop and rest if your eyes feel strained. You can reveal or skip every round.
Fuse the pair
Which shape appears closest?
Cross your eyes gently until the two dots look like three; use the middle fused picture. Landscape can be easier on phones.
