This puzzle is a classic visual logic test designed to trick your brain into making a quick assumption before checking the details. Despite the clickbait title about “Narcissism,” it actually measures attention to detail.
Here is the explanation and the solution:
The Breakdown of the Paths
If you look closely at the pipes leading to each cup, you’ll notice they are “blocked” by thin lines that act as seals.
- Cup A: The pipe is blocked at the very first fork on the left.
- Cup B: The pipe is blocked at the very end, just before it enters the cup.
- Cup C: The pipe is blocked at the start of its individual branch.
- Cup E: The pipe is blocked midway through the descent.
- Cup F: The pipe is blocked at the first fork on the right.
The Correct Answer
The only cup that will fill is Cup D.
It is the only path that is completely open from the coffee pot all the way to the rim of the cup.
