This whole idea of illogical hanjie with starting points given is just pointless and stupid. Even more so because it doesn't result in a pleasing image that was seemingly put care into.
The 8 Queens puzzle is a classic "logic puzzle?" I don't even know, where you're tasked with putting 8 queens onto a chess board where no queen is able to strike any of the others in one move. It's REALLY difficult, but there are 12 unique solutions (96 if you include rotations and reflections). Wikipedia explains the whole thing here: https://en.wikipedia.org/wiki/Eight_queens_puzzle Gewehrdalf has used the tenth solution from their list.
