What is it about optical illusions that drives everyone on Facebook wild? Is it because solving them makes us feel so smart and accomplished as we scroll through our news feed, clicking “like” on cute-kid photos and our friends’ latest updates?
Whatever the reason, these puzzles are addictive. So if you are still hankering after the panda in the sea of snowmen or the cat among the owls, see if you can do this challenge in under a minute, or, better still, 10 seconds.
Ready, set, go!
