This puzzle was created by me as a single-player variation on the game of go. The objective here is simple: capture all 41 grey stones on the board below in the least number of moves.
Just like in the game of go, capturing a stone happens when a stone has no more liberties. Each stone has 4 liberties that must be taken (as shown in the image below).
You are given four stones, each a different colour: red, green, blue and violet. The order in which you place these 4 stones is determined by the "colour wheel" below. First red, then green, then blue, then violet, then red again, etc. Skipping a colour still counts as one move. Remember that you only have four stones; so when you go to place a new stone, you will be removing it from it's previous position.
- You can place your stones anywhere you wish (including on top of other stones or even suicide).
- You cannot lose your stones (in the case where you suicide).
You can post your answer as a list of x, y coordinates of where you placed your stones. If you skipped a colour, treat it as though you moved the stone to the same spot (i.e. write down the coordinate of where the stone is currently at).
Sadly I don't have a program right now that can simulate this puzzle within your browser. I would however be willing to offer a bounty if someone could provide me with one :)
