Brain teasers are a brilliant way to pass the time if you're looking for a fun challenge to occupy your thoughts for a little while. But the seemingly simple games also have a number of real-world benefits. Not only can gameplay boost your concentration skills and memory, it never hurts to put your powers of observation to the test.
While most of us don't need to be as watchful as we once were, hazard perception is nonetheless an important skill.
So why not put your eyes to the test with our latest brain teaser? Your challenge: spot the snow leopard hidden in this nature snap in 10 seconds or less.
Good luck, you might need it. With their white-grey coat and majestic fur, snow leopards are known for their spectacular natural camouflage. So great is their ability to blend in with their surroundings, the big cats are sometimes known as the "ghost of the mountains" according to WWF.
In this instance, the remarkable photo, taken by photographer Inger Vandyke, shows the elusive predator stalking its prey. Inger, from Australia, spent 17 days in the mountains in Ladakh, India, with colleague Mark Beaman to track down the hunters.
