This Breathtaking ‘Spot the Difference’ Quiz is Seriously Tough

Have you ever traveled somewhere that completely took your breath away? Maybe it’s the vastness of the ocean, or finally being able to see every star in the sky. Maybe it’s the stunning cityscape of a place you’ve never been or the explosion of fireworks on a dark summer night. That feeling of experiencing something so surreal sticks with us, and creates a memory that stays with us for the rest of our lives.

This quiz will show you a series of photographs of places like this. But, there’s a catch: in each set of four, one of the photos will have a tiny detail that’s just a bit off from the rest. It’s your job to decipher which pic is unlike the others. Think your eyesight is stellar enough to get 100 percent? Or will you be left squinting an inch from the screen, trying in vain to catch the difference? Put on your thickest pair of glasses, grab a magnifying glass, and let’s get started!

Warning: this quiz may leave you cross-eyed.
