On Reddit, one optical illusion has gone viral. The picture shows six girls sitting on a couch, but you can only see five pairs of legs. It appears as if one person is missing a pair of legs, and on the online forum, people have tried to find the solution.

Per The Tab, one person wrote, The second girl’s legs are behind the first girl’s legs,” meaning that the one girl sitting second from the left hides her legs behind the one sitting farthest to the left. You can’t see it – but that is what makes it a brain teaser.

Optical illusion – find the ‘missing’ legs

Another user took on the optical illusion – and appeared to have cracked the code. User ElMangosto shared his own picture with the solution.

“Left to right, #1, #2, #3, #4. Number 1 has her legs crossed, and no tear in the knee. Number 2 has only one leg visible, the tear is in her knee. Those legs are blending together. (Follow that tear down, there’s a split where there’s a sock on the right and not on the left. Number 2 has a tear in her knee and a visible white sock) Numbers 2 and 3 are leaning way over. It’s easier to visualize if you picture #3 with her hand on the seat behind #4’s back to hold herself upm,” he wrote, and added the “solution.”
