Is there a clear delineation between the possible mathematical puzzles that can be posted only here and the ones that can be posted only in Puzzling Stack Exchange? Or there could be an overlap?
I have come to this understanding that people who ask about a puzzle's solution in Puzzling Stack Exchange are allowed to know the answer. But in here we do not do that and the only valid way to do that is to ask about a possible different solution.
So my question is about the puzzles themselves and not whether the poster knows the answer or not. Look at the following post for example.
This is a non-mathematical puzzle in disguise. At first glance it seems that there could be a mathematical answer to it but there is not. So assuming that the poster of such a question does not already know the answer (which is non-mathematical) was it appropriate for the above question to be posted here instead of Puzzling Stack Exchange?
Thanks for your attention.
