Mindboggling puzzle challenges people to spot the pink ring on the playground floor - but can YOU find it?

A mindboggling puzzle has challenged people to spot the pink ring on a playground floor in what is a fiendishly difficult brainteaser. 

The optical illusion was posted to the Reddit thread Find The Sniper, and requires you to look for a pink children's ring hidden in on a playground floor. 

Not only does the shade of tarmac in the picture make this puzzle tough to solve, but the ring complicates matters further by being exceptionally small.

With both of those factors to contend with, have another look to see if you can locate the ring before a clue is revealed below. 

If you are still having trouble finding it, keep looking from left to right as you peruse the image. 

Cast your eyes just off the centre of the picture to the bottom left and you should be able to locate the ring. 

Given the hazy background, you may also need to zoom in to be able to find it without assistance.  

If you have not been able to do so, the answer is revealed in the form of a circled image below.

Responding to the optical illusion, other users shared how they found it extremely hard to solve, commenting: 'Found it. Lost it. Found it again. Lost it again.' 

'This happened to me. I took the photo and could not find it in it for the longest time even though I knew where it was!'

'Wow, you literally can’t find it unless you zoom in. At least on my phone, anyways.'

'I actually found one without checking the comments for clues'. 

If attempting to work out this brainteaser has worked up your appetite for solving them, see if you can spot the hidden dice lost on a paint-speckled surface.

While finding a dice may not sound like the toughest of challenges, the pattern of the background makes it a tough optical illusion to crack.

If you have been staring at the image intently and are still unable to find the dice, have another look before a clue is revealed. 

Should you still be struggling, cast your eye to the centre of the image and track it slightly to the bottom left of centre. 

There, among all the grainy confusion, is one hidden dice that has shown to be rolled with a five.
