Only Special People Know Which Cup Fills First

We all love a good puzzle, especially when it comes with a bit of a challenging question.
Viral riddles that ask us to find hidden objects or solve visual conundrums are all the rage, keeping people on the edge of their seats as they try to crack the code. These puzzles aren’t just about finding something—it’s about seeing the unseen, using logic, and thinking outside the box. Today, we bring you a mix of some of the most challenging viral riddles out there. Do you have the keen eye and sharp mind needed to solve them? Let’s find out!
This riddle is all about logic and careful observation. At first glance, it looks like a simple series of cups and pipes, but it’s much trickier than it seems. Your task is to figure out which cup will fill up first when liquid is poured into the contraption. Many people are quick to give their answers, but it’s easy to miss a critical detail that changes the entire outcome.
Take your time to analyze the layout. If you examine the pathways closely, you’ll notice that several cups are blocked. The paths to cups 7, 5, 4, and 3 are closed off, meaning these cups won’t fill up at all. The only open paths lead to cups 1 and 6. As the liquid enters the system, it travels down the tube, bypasses the blocked routes, and heads straight toward cup 6. Cup 6 is the one that fills up first. Did you manage to figure it out? If not, no worries—this one stumped a lot of people!
