Optical illusions have become one of the most popular ways to test vision, attention, and intelligence online. These mind-bending challenges are everywhere—from social media to brain-training websites—and they captivate audiences by forcing the brain to work harder than usual.
Can you find the numbers “00”, “04”, and “44” hidden inside a grid full of “40s” in just 9 seconds?
According to viral reports, only 1 in 100 people can solve it instantly. Let’s dive into how this puzzle works, why it’s tricky, and—if you gave it your best shot—where the hidden numbers are located.
Why Optical Illusions Work
Optical illusions play with the way our eyes and brain process images. There are three main categories:
- Cognitive illusions – trick your interpretation of reality.
- Physiological illusions – affect how your eyes respond to light and contrast.
- Literal illusions – make you see objects differently than they actually are.
This puzzle falls into the cognitive illusion category because it forces your brain to filter through repetitive patterns (“40s”) to find the impostors (“00”, “04”, “44”).
The Challenge- Find 00, 04 & 44 in 9 Seconds
Here’s the setup:
- The grid is filled almost entirely with 40s.
- Hidden within are three impostors: “00”, “04”, and “44.”
- You have just 9 seconds to spot them all.
Sounds simple? It’s not. The repetitive “40” design creates visual clutter, making it difficult for your brain to quickly detect slight differences.
Why This Puzzle Is So Difficult
- Repetition overload: Dozens of “40s” blur together, overwhelming the eyes.
- Small variations: “04” and “44” look deceptively similar to “40.”
- Time pressure: With only 9 seconds, stress reduces accuracy.
That’s why only 1% of people are able to spot all three numbers on their first attempt.
Quick Facts About the Puzzle
| Puzzle Detail | Information |
|---|---|
| Objective | Spot “00,” “04,” and “44” among “40s” |

Solution
Tried the puzzle? Here’s where you should have looked:
- “00” – Look vertically. Double circles stand out when scanned column by column.
- “04” – Notice the slim right-side line; it breaks the circle symmetry.
- “44” – Look for two vertical sticks side by side; diagonals help reveal it faster.
How to Train Your Eyes to Get Better
- Defocus your vision: Blur slightly, and odd shapes pop out.
- Scan in small blocks: Break the puzzle into 3×3 sections.
- Practice daily: The more optical illusions you try, the quicker your brain adapts.
These exercises don’t just improve puzzle-solving—they sharpen everyday attention and memory skills too.
The viral “00, 04, 44” puzzle isn’t just entertainment—it’s a clever way to test your ability to focus under time pressure. While only a few succeed within 9 seconds, everyone who tries strengthens their observation skills.
So, the next time you face an optical illusion, remember: whether or not you solve it fast, your brain is getting sharper with every attempt.
