The countdown to Halloween is well underway—and you can get ready to celebrate with this spooky brainteaser by puzzle expert Gergely Dudás. At first glance, the illustration looks like a normal Halloween design, but sharp-eyed observers will notice that one figure in the crowd doesn’t belong.
Hungarian artist Dudás, who goes by the pseudonym Dudolf, is known online for his whimsical seek-and-find pictures. His illustrations consist of groups of cute cartoons, always with oneout-of-place object blending into the crowd. In the past, he's hidden a sheep among a crowd ofSantas for Christmas, a heart among snails for Valentine's Day, and an egg among a tulip field for Easter.
His brainteaser for Halloween is more of a trick than a treat. The image is full of white skeletons, with just a handful of orange jack-o’-lanterns breaking up the monochromatic scene. Somewhere in the crowd, Dudolf has tucked away a white ghost. Test your observation skills by scanning the interactive illustration below for the hidden specter. Once you think you’ve spotted the ghost, simply click the image to find out if you’re right or wrong. You have unlimited guesses—good luck.
