🔍 How to Count the Holes
When looking at a standard T-shirt, most people initially count:
1 neck hole
2 arm holes (sleeves)
1 body opening (bottom)
That equals 4 holes, right?
But here’s where the puzzle gets tricky:
Each “hole” in a T-shirt actually has two openings—one on the inside and one on the outside. Think of it this way:
Hole Location
Outer Opening
Inner Opening

Visual Explanation:
Imagine putting the T-shirt on:
Your head goes through the neck hole (that’s 2 openings: front and back)
Your left arm goes through the left sleeve (2 openings)
Your right arm goes through the right sleeve (2 openings)
Your torso goes through the body opening (2 openings)
Each hole is a tunnel with an entrance and an exit.
🧠 Why Only 1 in 7 People Get It Right
This puzzle stumps so many people because:
Reason
Explanation
Assumption bias
We assume “hole” means a single opening, not a tunnel with two ends
Visual thinking
We look at the shirt from one angle and count what we see
Overthinking vs. underthinking
Some people overcomplicate it; others don’t think deeply enough
Language trick
The word “hole” is ambiguous—does it mean an opening or a passage?
💡 Key insight: This puzzle isn’t just about counting—it’s about perspective. It challenges you to think three-dimensionally about a seemingly simple object.
