Inspired by Quantum Go and Entangled Go
There are N boards that “look similar”, and every move places a stone on each board at the same position.
However the boards are slightly different. For example there could be K holes that are randomly distributed among all positions.
If a move is illegal on a board (e.g. due to the position being a hole), then it takes no effect on this board.
Don’t have a good title, because “Parallel Go” and “Entangled Go” are already taken
