How sharp is your brain? Only a few can spot the inverted 42 among the inverted 24s

If you think you have got sharp eyes, like those of a hawk, then this might be just for you! In the above image, one can see a grid filled with what look like identical numbers, rows and rows of red coloured numbers, but look again! Hidden among the inverted 24s is a SINGLE inverted 42, the task is simple: Find it and write the answer in 7 seconds!

This is more than just a game, optical illusions are fun way to get the power of distinguishing between the same elements, it lets us see how our brains perceive differently from others. Instead of reading numbers individually, the brain is wired to recognise the different patterns and groupings, this is why many people often miss the odd one out, even though, it is hiding in plain sight. It is not about how smart you are, it is about how the brain chooses to focus.

How to spot the odd one out!
These types of puzzles test our attention to detail and short-term visual memory. The brain gets flooded with all the repetitive patterns and tend to get on "autopilot" mode, even after seeing the odd number, the brain tricks us that it might be just the same as others, but in reality, its the odd number right in front of us! in this case, the twist is subtle, a 42 instead of a 24, flipped upside down to make it even trickier to detect.

Don’t worry! Most people need more than one attempt. A good strategy is to scan each row slowly from left to right, or even try tilting your head slightly. The change in angle can sometimes help break the brain's habit of auto-grouping the numbers.

Ready for the reveal? We won’t spoil it just yet and give ourselves a fair chance. If you can find the inverted 42 in under 7 seconds, congratulations! That puts you in a small group of people with exceptionally sharp perception skills. If not, don’t be discouraged. It’s all part of training your brain to slow down, look deeper, and focus.

So did you spot it?
