It's always good to give your brain a workout and brainteasers are a brilliant way to test your cognitive skills and challenge your eyes.
As well as keeping your noggins active, tackling a tricky optical illusion is a fun activity to pass the time - but they can also leave you scratching your head.
This Easter themed seek-and-find puzzle, created and shared by Instantprint, challenges you to spot six Easter eggs that have been hidden within the busy office scene.
On average, it takes 76 seconds to spot all six eggs hidden in the brainteaser – but can you find them quicker than that?
Even the most avid puzzle-solvers have had trouble locating all six eggs dotted around the picture - so it's pretty tricky.
According to the creators, just one in five are able to spot all of the colourful eggs in under a minute, which is very impressive.
Still stuck? If you'd like a little more time to solve this extra hard brainteaser, don't scroll down just yet as the image below reveals where the Easter treats have been hidden.
In recent weeks, we have seen some other fun examples of tricky brainteasers and optical illusions.
For those of you who want to test yourselves further, you could try your hand at this one where the challenge is to find a seahorse lurking somewhere in the aquarium.
Or you could have a go at one which tests how well your brain can analyse an image, as not all the strands of seaweed are the same - but finding the odd-one-out is far from easy.
Did you manage to spot them? Let us know in the comments.
