Find the Inverted 72: Have you ever tested how fast your eyes can catch tiny details? This optical illusion IQ test will put your focus and attention to the ultimate trial. The puzzle looks simple, but don’t be fooled—hidden among a group of inverted 75s is a single inverted 72, and you need to spot it in just 6 seconds.
It’s not only a fun brain teaser but also a way to measure how sharp your observation skills are. Let’s dive in and see if you can spot the difference before the timer runs out.
The Challenge

The puzzle is a grid filled with inverted 75s. Somewhere in the middle of this pattern hides an inverted 72. The challenge is to find it before 6 seconds pass.
The tricky part? Because the numbers are flipped, they look very similar at first glance. Your brain processes the repeating 75s quickly, making it harder to notice the one odd number. This is exactly why optical illusions are so effective—they trick your eyes and mind into missing the obvious.
How to Spot the Hidden 72
If you’re struggling, here’s a tip: focus on the second digit of each number. Most of the numbers will end with 5, but one of them will end with 2. That’s your clue.
The answer: The inverted 72 is in the third row from the top and the second column from the right.
Once you locate it, the difference becomes very clear, and you’ll wonder how you missed it before!
The Solution
If you didn’t manage to find it in time, don’t worry—you’re not alone. The hidden 72 can be spotted in the third row, second column from the right.
Many people fail on the first try because the illusion takes advantage of how our brains process repeated shapes. But spotting it means you have strong observation skills and quick recognition ability.
If you spotted it within 6 seconds—congratulations! That’s proof that your focus and attention to detail are above average.

Why Optical Illusions Work
Optical illusions are more than fun internet games. They highlight how our brains often choose “speed” over “accuracy.” When the mind sees repeated shapes, it groups them together and overlooks tiny differences.
By practicing puzzles like these, you train your brain to:
- Notice small details more quickly
- Improve focus and memory
- Strengthen problem-solving skills
In fact, researchers say solving puzzles regularly acts like a mini workout for your brain. It improves concentration and sharpens thinking skills over time.
