What’s the special feature of this optical illusion?

This puzzle isn’t just a fun puzzle, but also a test of your concentration, observation, and mental agility. When you look closely at these numbers, your brain tries to recognise patterns.

Many people get confused because the numbers “54” and “43” are deliberately arranged in a way that resembles “45.”

Those who spot these subtle differences in 7 seconds are considered to have exceptional visual recognition and mental agility.

How to Find the Hidden Numbers

To solve this puzzle, carefully scan the screen and focus on the numbers in each row. The upside-down ’54’ is hidden in the top row, on the right. ’43’ can be found in the fifth row, on the left. At first glance, it looks like ’45,’ but upon closer inspection, the numbers appear to be interchanged.

Why are such brain puzzles popular?

These optical illusions test our brain’s ability to think and perceive. The science behind them is that when we see a pattern repeatedly, the brain creates the illusion of “similarity”-making small variations invisible.

Such activities improve visual processing and help increase mental concentration.
