Gergely "Dudolf" Dudás has a way of turning simple images into mind-numbing puzzles. Look closely at his amazing illustrations of squirrels, snails, and rabbits, and you'll find an object that doesn't belong in each one. This new image from the artist features a doe hiding in a crowd of stags, and it may be one of his toughest brainteasers yet.
Most of Dudolf's hidden image puzzles pair items that look similar. In the image above, the only difference between the doe and the stags surrounding it is the lack of antlers. You may have to study a lot of deer heads before finding the animal that's out of place. If you're feeling impatient, you can check the solution at the bottom of the page.
