Posted by Facebook user Arshdeep Soni, the image in question features a three-dimensional arrangement of blocks on an orange background. The blocks are stacked in a stair-like formation, prompting viewers to figure out how many there actually are. The challenge lies in its deceptive design — what appears simple at first glance becomes more complex the longer one looks.

The puzzle that’s got everyone counting

The image comes with a straightforward question: “How many blocks?” Viewers are given four options to choose from — 7, 8, 9, or 10. However, the optical illusion plays tricks on the eyes, making it difficult to arrive at a definite answer. Some blocks seem to blend into the background, while others appear to be part of multiple layers, adding to the confusion.
