Optical illusion: Can you find 54 and 55 among the 45s within 5 seconds?

This puzzle looks straightforward, but it is more complex than you think. The figure of 45 is concealed in a grid of two odd numbers: 54 and 55. Can you spot them within 5 seconds?

On initial observation, all the figures seem the same. That is why our brain is programmed to detect patterns quickly and naturally to fill in the gaps. With the same-looking figures, such as 4 and 5, coming in succession, it becomes more difficult for our eyes to detect a slight difference, such as a 4 replacing a 5.
It is an optical illusion that challenges your eye, eye for detail, and visual wit. It appears as though it is a basic puzzle game, but these drills are applied in mind training to hone concentration and acuity of mind.

How to do it

• Look from left to right, top to bottom.
• Don't be distracted—look out for something that seems out of the ordinary
• Take your time examining the direction of the digits: "54" and "55" flow differently than "45."

Found both of them yet? If so, try again without rushing. This isn't just a test of your vision—it's a test of how your brain perceives this image.
