A viral spot-the-difference puzzle featuring a grandmother doing a yoga tree pose has been challenging people online. At first glance, the two illustrations look almost identical, but several tiny changes are hidden in the image. The challenge asks viewers to find the difference before checking the answer.

The first difference is on the foot she is standing on. In the left image, the grandmother appears to have five toes, while the right image is missing her pinky toe, leaving only four visible toes. It is an easy detail to overlook because most people naturally focus on her pose and face rather than her feet.

The second difference can be found at the bottom of her pants. The left image has a distinct dark green trim along the bottom of the pant leg, while that line is missing from the right image. The third difference is hidden in her beaded necklace. Two beads on the right side of the middle strand have been changed from the original red color to a darker brown shade.

That is what makes this puzzle so sneaky: the differences are extremely small and placed in areas your eyes may naturally ignore. So before scrolling to the answer, take another careful look at the grandmother, her foot, clothing, and necklace. Did you manage to spot all three differences without help?
