At first glance, this picture appears to show a peaceful landscape with a large tree and two people standing near the bottom. But look a little closer, because the scene contains hidden faces cleverly blended into the artwork. The challenge is to discover all of them without letting the obvious figures distract you.

Start by examining the tree, including its branches, trunk and the spaces between them. Some faces are easy to recognize once you know what to look for, while others are created from lines, shadows and natural shapes. Instead of looking only for complete faces, watch for details that could form eyes, noses, mouths or profiles.

The puzzle works because our brains quickly organize what we see into familiar objects. Once we identify a tree, for example, we tend to keep seeing it as a tree rather than searching for another image within its branches. Hidden-face puzzles encourage us to change our perspective and notice shapes that might otherwise be overlooked.

If you’re having trouble, try looking at the image from a little farther away and then moving closer again. Examine the negative spaces around the tree and don’t ignore the edges of the picture. Give yourself time to scan the entire scene instead of concentrating only on the two obvious people.

How many people can you find in this picture?

So, how many people can you find? The complete puzzle contains 10 hidden faces. Some may become obvious quickly, while others can take much longer to recognize. Once you discover them all, take another look—you may be surprised by how many details were hiding in plain sight!
