Why This Puzzle Works So Well
Our brains are wired to recognize patterns. When we see the same shape repeated over and over, we stop looking at the details and just “assume” everything is the same. That’s why the letters “n” and “m”—which are almost identical except for one tiny extra hump—are the perfect duo for a trick like this.
Think about it: when you’re reading a book, do you stop to notice every “m” and “n”? Of course not. Your brain glides over them effortlessly. This puzzle takes advantage of that, forcing you to slow down and really see what’s in front of you.
