Brain teasers aren't always easy to solve, but they can be fun and work wonders for our cognitive function by improving the brain's ability to perceive and interpret visual information.
And while you might struggle with complex brain teasers at first, the more you practice, the faster you'll be able to work them out - and before long, you'll be cracking tough puzzles in seconds.
So, if you're looking to give your brain a workout, why not try your hand at this new optical illusion that has been leaving some people scratching their heads?
All you have to do is find the two antelopes standing among the rocky mountainside pictured below.
Have you found them yet?
They can be pretty tricky to spot at first glance, but according to education centre, Jagran Josh, you'll have to find both antelopes within just five seconds if you want to consider yourself someone with "high brain power".
If you're still struggling, let us give you a hint.
You'll need to scan every inch of the picture if you want to find the majestic mammals, as they blend in perfectly with the brown colours of the rocks, grass, and leaves that litter the scene.
However, you can forget about searching for anything to the left of the white tree in the picture, as both antelopes are to the right of it. One of them is toward the front of the image, and the other is in the background.
Got it now? We'll be giving you the answer just below, so consider this your spoiler warning!
