Can you identify the series of numbers in this black-and-white swirl?
Who doesn't like a good old mind-boggling visual puzzle? Here's one that caught our eye.
Twitter user @benonwine shared an image that shows a number that is concealed in a striped black and grey circle. Since then, it's left the internet in a tizzy. How many numbers are there? And what are they? There are several hidden numbers: the numbers are on one level and the swirls are on the other. How many can you spot?
DO you see a number?— Benonwine (@benonwine) February 16, 2022
If so, what number? pic.twitter.com/wUK0HBXQZF
Here are some of the responses:
I can only see 528. Does that mean anything about my eyesight?— (((Louise Cooke))) (@CookeLouise) February 17, 2022
1528— Ann Coates 🦕🦖 (@setoacnna) February 18, 2022
I see, 5283— Di P-W koala lover Scotty troll sewer rat 🐨🐨 (@DiPw122) February 21, 2022
One person joked: 45 283...and what's the catch? Should I book an appointment with my GP? Another wrote: I can see 45283, since looking at the other replies I’ve others are seeing 2 other numbers. I can see there are numbers there but can’t make them up.
Take a hard look at the screen. Can you see what they're seeing? Yes? No? Okay, it's time for the big reveal....
Well, the correct answer is 3452839.
Did you guess it? Once that was pointed out to the Twitter users, some people said that they still couldn't see the numbers towards the extreme ends!
45283? Can't make out extreme left or right?— Bagpuss Grognard (@davepaters) February 18, 2022
Initially 15283 then I expanded the image and it became 3452839 !— Roger Barrett 💙 (@rogerkb2012) February 18, 2022
3452839, but to be honest the first 3 is a bit of a guess. Can’t get a fix on it. Easier to see if you jiggle the image up and down, but I don’t know why.— Richard Miller (@miller_klein) February 17, 2022
I can’t see them even though I know they’re there 😢— Lotto (@Lotto688Lotto) February 17, 2022
Nope! Now I know there are numbers at the ends, I can vaguely make out shapes, but still can’t work out what numbers they are.— Violet Brown (@B69Violet) February 17, 2022
I'm guessing the numbers you see depends on your 'contrast sensitivity' (different from what a standard eye measures). It can be tested by opticians. Worth doing if you're struggling, as it can affect your ability to see at night, or in rain, fog, etc.https://t.co/PRDru2sTEC— Phil King (@LittleToRelate) February 17, 2022
According to The Daily Mail, this particular puzzle works by playing on contrast sensitivity. This is an important visual function when people are trying to separate objects from their backgrounds. It comes into effect during real-life situations such as driving in low light or fog. Here, the viewer needs a higher level of contrast sensitivity so that the contrast between objects and their backgrounds is reduced. Eye conditions like cataracts or glaucoma can cause poor contrast sensitivity. If you have a higher level of contrast sensitivity you've probably spotted all 7 digits immediately.
Stay tuned for more fascinating visual puzzles!
