This is probably why these puzzles fool people.
The brain recognizes the object immediately.
It sees “shirt” and retrieves a familiar mental model.
That mental shortcut works perfectly well in everyday life.
But puzzles are designed to punish shortcuts.
The moment the shirt is damaged, that familiar four-hole model becomes much less reliable.
Then the Tears Change Everything
Now imagine the shirt has several large tears.
Some are on the front.
Some are on the back.

Suddenly, the original four openings may no longer be the entire answer.
The difficulty comes from deciding whether each visible tear should count as:

– An opening connected to another opening

But if the paper is folded, the situation becomes more complicated.
Suppose you fold a sheet in half and punch through both layers. Did you make: AccessWriting Tools
one hole through the folded sheet?

A shirt isn’t a flat sheet of paper.
It is a three-dimensional garment.

If a tear passes through the front and back panels, you may see an opening from the front and another opening from the back.
Some people count those as two holes.
Others count the entire passage through the garment as one hole.
The difference comes from the definition being used.
This is why declaring that there is only one “correct” answer without explaining the counting method can be misleading.
Think of the Shirt as a Container
One useful way to approach the puzzle is to imagine the shirt as a hollow object. SolveBrainteaser Puzzles
