TikTok star Hectic Nick shared the brain teaser with his more than 3million social media followers, revealing that only one percent of participants can solve it.
Most people who came across the optical illusion were immediately stumped.
The post gained thousands of comments as everyone made guesses as to what the solution was.
Some people believe there were 17 while others thought there were as many as 28.
Wearing his signature leather jacket and mirrored sunglasses, Nick sat in front of the camera and pointed to the image above his head, challenging everyone to take a guess but he wouldn’t say what the answer was.
How many sevens do you see?
“I spotted 1 straight away and ended up with 17,” wrote one viewer.
Another wrote: “28 if you count the ones that don’t close and the starting of each line.”
And a third said: “No it’s 19.”
If you’re a fan of optical illusions, you might want to try out this one – can you see where the giraffe is in this image?
The puzzle shows a dense thicket of trees with interlacing branches – seemingly too tightly woven to conceal a towering giraffe.
But there really is a giraffe hiding in plain sight somewhere in the picture – and you could have 20/20 vision if you spot it.
It’s important to look at the full picture when dealing with an optical illusion, but don’t forget – the devil is in the details.
If that was too easy for you, see if you can spot the hidden optical illusion tucked away in the Phoenix Suns jersey.
It’s not something that you’ll instantly get – but you’re clever if you can spot it quickly.
Fans have recently noticed it on social media, despite supporting the team for years.
This brain teaser is definitely worth a try.
