This one is super easy because it's been in the news. It (not the mobius variant) appeared on an SAT question that everybody gets wrong because the correct answer wasn't one of the options.
That seems impossible. Surely the test had one of the 4-5 multiple choices as the desired answer, even if incorrect. A percentage of people must have guessed it by accident, so the article title saying that everybody gets it wrong was, well, gotten wrong.
And no, I've yet to look at the hints
My favorite puzzles have often been just geometric.
My fave 5 piece puzzle: Arrange the 5 pieces into a square.
I also have a 'worlds hardest' 4 piece puzzle, both easily cut out of a piece of cardstock.
