Find hidden piglet in 'impossible' brainteaser and you're in the sharpest 2%

Fancy a brain workout? Give this mind-boggling optical illusiona go and see if you can crack it.

Brainteasers and puzzlesare a brilliant way to boost concentration and cognitive skills. By tackling these mini challenges- either solo or with friends and family - it's a cracking way to give your brain a "workout" and test your eyesight to the max.

Like most puzzles, this one isn't as simple as it first appears. The goal is to spot the hidden piglet in this "impossible" brainteaser, with only 2 per cent of people managing to find them. This is because the image is chock-full of other animals - and at first glance, there doesn't seem to be a pig in sight.

You'll spot creatures like two elephants, a lion, and a tiger - but that's not what the puzzle is all about. Take a gander below and see if you can spot the piglets.

There are plenty of things in the photo that might trick you into thinking you've found the piglets. The platforms that the horse and the purple elephant are standing on both feature pink circles with two black dots in the middle, and there's a ball to the left of the red elephant which also has similar details. Even the bunting has a porcine feel!

However, all the snout-shaped details throughout the puzzle are merely red herrings. The solution to the brainteaser will be disclosed below, so only continue scrolling when you're prepared.

Did you manage to crack it? The pig was concealed behind a ball to the right of the purple elephant. You can only spot a tiny fraction of its body, a curly tail, and two ears protruding above the ball, and if you peer really closely, you can glimpse a small section of its snout as well.

Was that enjoyable? If you're seeking another test, then why not attempt this exceptionally challenging A-level Maths question that's left most people baffled.

Over on TikTok, user @freemathstutor_uk, who boasts over 119.3k followers, shared a devilish maths problem that'll leave you scratching your head. Have a go at trying to solve it - the solution is revealed here, along with a step-by-step walkthrough.

The question states: "A team game involves solving puzzles to escape from a room. Using data from the past, the mean time to solve the puzzles and escape from one of these rooms is 65 minutes with a standard deviation of 11.3 minutes. After recent changes to the puzzles in the room, it's claimed the mean time to solve the puzzles and escape has changed. To test this claim, a random sample of 100 teams is selected."

"The total time to solve the puzzles and escape for the 100 teams is 6,780 minutes. Assuming the times are normally distributed, test at the 2% level the claim the mean time has changed."
