A number is hidden in this optical illusion — and not everyone noticed it the same way

Step 3: Change Your Perspective

If the number doesn’t appear right away, try these tricks:

1. Step back: Moving a few feet away from the screen can sometimes make the hidden number more obvious. Distance reduces the dominance of distracting patterns.
2. Squint your eyes: Squinting softens the contrast and can make the hidden figure emerge from the background.
3. Tilt your head: Looking at the image from a slightly different angle can help your brain reorganize the shapes and reveal the hidden number.

Step 4: Use Pattern Recognition

Focus on isolating potential numbers. Many optical illusions rely on shapes that resemble the digits 0–9. Mentally scan the image for:

• Curves that could form the number “6” or “9.”
• Straight lines forming “1,” “4,” or “7.”
• Rounded shapes for “0,” “3,” or “8.”

Sometimes, your brain needs to be prompted to switch from seeing random shapes to seeing a coherent number.

Step 5: Verify by Outlining

If you think you see a number, try outlining it with your finger on a touchscreen or on paper. This exercise helps you confirm whether your brain is actually seeing a number or just imagining it. By tracing it, you reinforce your visual perception and can often spot hidden details you initially missed.

Step 6: Appreciate Individual Differences

It’s fascinating that not everyone sees the number in the same way. Factors such as age, eyesight, brain processing style, and even mood can influence perception. Some people might instantly see the number, while others may require several attempts. That’s the magic of optical illusions — they remind us that perception is subjective.

Conclusion

Hidden-number optical illusions are more than just fun puzzles. They are a playful reminder of how our brains interpret the visual world differently from person to person. By carefully observing, changing perspectives, and using pattern recognition, anyone can improve their chances of spotting the hidden number. The next time you encounter such an illusion, take your time, explore different angles, and enjoy the delightful challenge of seeing what others might initially miss.
