Mindboggling brainteaser challenges people to spot the hidden dice... but can YOU find it?

A tricky brainteaser has challenged Brits to spot the hidden dice lost on a paint-speckled surface.

Posting to Reddit's popular Find The Sniper thread, user @Cutte_Riley shared the image, which received more than 350 likes from fellow users. 

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.

If attempting to work out this brainteaser has worked up your appetite for solving them, see if you can spot the hidden nail among a sea of screws.

Finding the lone nail is undoubtedly a tough task, as it is concealed around a number of screws that are almost identical in colour, shape and size. 

Given that it is such a tough puzzle to solve, see if you can do so in 15 seconds or less to prove your mental sharpness.

If you managed to solve the devilishly difficult brainteaser, give yourself a pat on the back as that was an extremely tough task. 

After other Reddit users were able to solve the optical illusion, they took to the comments section to give their best nail and screw-related puns in response, joking:

'Nailed it'. 

'Thought he was screwed.'

'We can just say he put the final nail in the coffin'. 

'Anyone willing to find it has at least one screw loose.'

'Gosh he really nailed that one'.
