None of them made a square. Then one student drew all four sides first and added three lines inside the box, which is exactly what the instruction asked for. That 50-second classroom clip, posted as a YouTube Short by a teacher in India who goes by Raviraj Master, had 137,721,101 views when we checked his channel on November 5, 2026. It went up on April 28, 2025 (Pacific time), and it is circulating again this year in brain-teaser roundups. Why a classroom of kids missed it Our take: the puzzle is not hard, it is badly lit. Every student read “with” as “using,” and once that reading clicked into place nobody went back to check it. One of them got closer than the rest by drawing three solid sides and a dotted fourth one, a clever dodge that still breaks the rule it is trying to obey. The fix was reading the sentence again. “With” can mean “made from,” but it can also mean “together with,” the way you order a coffee with milk. Read that way, the task asks for a square that has three lines alongside it, and the student who drew lines inside the square simply took the second meaning. Logicians have a name for one word carrying two senses inside the same argument: equivocation, an informal fallacy that comes from failing to pin down your terms. Here it is harmless. The same trick shows up in slogans and fine print, where a word like “fair” or “free” quietly shifts meaning between the promise and the delivery. Other ways people have cracked it The riddle is older than the Short. On a math discussion board in October 2018, a user posted a stricter version, “Using 3 straight lines only, draw a square,” and the regulars answered within a day with number puzzles rather than geometry. Put next to the classroom answer, the known readings look like this: Draw the digit 4 with three strokes, since 4 is a square number (2 squared). Draw shapes that read as other squares, such as 9 or 100, using combinations of straight strokes. Draw a square of any size and add three lines to it, the classroom solution. Each answer works by changing what “square” or “with” refers to, not by bending the geometry. That is the move Maltese psychologist Edward de Bono called lateral thinking when he coined the term in 1967, using puzzles such as the nine dots problem as examples. Critics have argued his framework was never rigorously tested, so treat it as a handy label rather than proven science. What the clip shows, and what it does not As a piece of teaching, the format is smart. Letting students fail in public, one after another, builds the tension that makes the final answer land, and it rewards rereading the question over speed. As evidence, it is thinner. The Short carries no description beyond its title and hashtags, so there is no word on the school, the grade, how many takes were filmed or whether the winning answer was planned for the camera. Viewers have no way to tell a spontaneous solve from a rehearsed one. The numbers are easier to pin down. Spread across the 555 days between its upload and our check, 137.7 million views works out to roughly 248,000 views a day on average, every day for a year and a half, for a riddle whose answer takes one extra square of chalk. If you want to try it on your own class or family, write the instruction exactly as the teacher did, say nothing else, and wait. The clip’s 137,721,101 views suggest most people will draw three lines first.
