But with the sharpest of eyes and the strongest of minds, you stand a great chance of victory. Even those with perfect observational skills are likely to pass this test before it gets the better of you. And by searching every single part of this image, you stand a higher chance of finding the hidden number before it’s too late. In the image provided by Jagran Josh, we can see what appears to be a canvas covered in different coloured paints. The montage of colourful dots makes it incredibly difficult to decipher where the number could be – as well as what number it is. But hidden within this image is a number that only people with “4K vision” can see. With so many colours to look at, it can be quite an overwhelming task. It might look like a daunting challenge, but we know you’ve got what it takes to get the job done. If you can make sure you check every square inch of the picture, then you should be able to uncover the carefully hidden number. Make sure you also think outside the box, too, as this isn’t necessary as simple as it seems. So, without further ado, off you go – and good luck. If you are struggling however, then we can offer you one clue to help you succeed; look in the bottom half of the image! If you still can’t find the hidden number, then it has been circled for you below. How does an optical illusion work? By Tom Malley OPTICAL illusions are a great way to test your eyesight and cognitive skills, requiring you to really think about and observe what’s in front of you. More often than not, players are required to find something hidden within an image that can’t immediately be found on a first glance. But the more you stare at it, the more your brain tries to help you find the answer. What you see and what you think you see are two completely different things, but your senses gather information and send it your brain. Your brain then creates a perception with this information, whereby it fills in gaps when there is incomplete information, or creates an image that isn’t even there. This reaction is actually a survival instinct. Our brains have evolved to quickly work to piece together any information it can get, before doing its best to figure out the rest. So when you’re looking at an optical illusion, your brain works with what it’s got to develop a reality in order to help you see the answer in the image.
