Optical Illusion IQ Test: Are You A Genius? Within 5 Seconds Spot The Number 4 among 5 - Solution
In this optical illusion IQ test, the challenge was to spot the number 4 hidden among a grid full of the number 5. At first glance, the uniform arrangement of 5s makes it hard for the eye to detect any difference, especially under the pressure of the 5-second time limit.
However, if you scan the grid carefully, you’ll find the number 4 located at the bottom right corner of the image. Unlike the rounded curves of the 5s, the 4 stands out with its straight edges and distinct shape once you focus on the details.
The red circle in the image highlights its position, proving that even a subtle variation can be hidden effectively in a repetitive pattern. Spotting it quickly is a true test of sharp eyesight and rapid visual processing!
