Thanks for this OP. Really enjoyed finding solutions, and of course reading comments about all crazy looking solutions as well. This is the stuff that keeps me hooked to HN!

I remember being given another puzzle in my childhood, where the task was to put 8 queens on the board and none of them should "see" each other. Wonder how many solutions exist for that one..

ETA: Apparently it's a classic puzzle, and there are 92 solutions - https://en.wikipedia.org/wiki/Eight_queens_puzzle
