Brainteasers are a quick way to keep your mind sharp, helping you to think outside of the box to find a solution.
Known to help improve memory, cognitive ability and improve your brain health in the long run, they are fun ways to help you stay focused on one task at a time.
They work by challenging your ability to spot hidden objects that are tricky to see at first glance, or anomalies in busy images.
The latest puzzle from FreshersLive asks you to find the number 8881 in a sea of 8831s. Even worse, there's a time limit of just 12 seconds - so you're really up against the clock.
You'll need to really observe and analyse the picture so you can spot the number, but remember, there's a seriously strict time limit when it comes to this brainteaser.
The number is really well disguised, making it a mind-boggling feat. For some people, their eye will be instantly drawn to where the anomaly is - but for others, it'll be more of a struggle to find the odd number out.
We'd suggest breaking it down into sections, tracing each part with your eyes quickly so you can gauge where the different number is. But make sure you're concentrating, otherwise, it may just pass you by.
Be creative - sometimes, the solution to a brain teaser requires out-of-the-box thinking.
