The Challange
In this optical illusion IQ test, the task is to spot the hidden number 0 cleverly hidden among a grid of 3s—all within just 5 seconds. At first, all digits appear the same, but if you focus more, it reveals the sneaky 0 tucked within the pattern.
Take the test
Relax and close your eyes before taking the test. Now, open your eyes and focus on the grid and try to find the hidden 0.
Not able to find it yet? Focus more!
Hint
The hidden number is positioned on the far left side.
Did you find the number now?
Are you a genius?
If you found 0 within 5 seconds—congratulations! That is a strong sign of keen observation and sharp visual perception.
The hidden 0 was positioned on the far left side, just a few rows down from the top. Its curved shape blends seamlessly with the 3s, making it difficult to spot.
