The two holes visible on the front of the t-shirt are therefore also present on the back. We don’t always notice them, because our gaze naturally stops on what is directly in front of our eyes.
This is where the enigma gets really interesting… and that the answer shifts.
The final (and correct) answer
Let’s go back to the final calculation:
1 head hole
2 arm holes
1 hole at the bottom
2 visible holes on the front
2 matching holes on the back
Total: 8 holes
Yes, 8. An answer that seems exaggerated at first, but which becomes obvious once the explanation is put in black and white.
Why this puzzle works so well
This challenge is extremely effective, because it is not based on mathematics or on any particular knowledge. It simply highlights the way we perceive objects. We see what we think we need to see, not always what’s actually there.
That’s also why this kind of viral visual challenge spreads so easily: it provokes that little moment of surprise, followed by a “But yes, of course!” that immediately makes you want to share it.
A great exercise for the mind
Visual puzzles like this are real mini-gymnastics for the brain. They force us to slow down, to observe differently and to question our certainties. And let’s be honest: there is a certain pleasure in discovering that we have been trapped… before being able to trap others in turn.
And you, did you find it?
If you answered 8 on the first try, congratulations: you are part of the ultra-attentive minority. If you haven’t, rest assured, you’re in excellent company.
The next time you put on a t-shirt, it’s a safe bet that you’ll think of this surprising visual enigma… and that you will never look at your clothes the same way again.
