I think that’s up to you and your rule. =]

Is there a way to change the board size in the tool you created?

and could you change the resolution of the saved image to something like 150x150?

Yes, go the the address bar and put https://rubymineshaft.github.io/ instead :sweat_smile:

A nifty little feature I added to my tool indeed :stuck_out_tongue:

I was working on something else for the next rule I create, so it’s a bit inconvenient for me to update my site right now unfortunately.

Ok Here we go. This rule is invariant to rotation and mirroring.

Confirmed Structural Properties (Spoiler)
  1. There is no red Koan without black stones.

  2. The rule uses the concepts of chains and liberties.

  3. The rule could be applied to arbitrary graphs and is independent on the drawing of the graph.

  4. The rule does not refer to shared liberties.

  5. The rule cares about the number of stones in some way.

  6. If a green Koan has at least one black stone, adding or removing a white stone always changes its color to red.

Koans that know Buddha-Nature:

Solution (solved by le_4TC)

Every black chain needs to have the same number of liberties as the total number of white stones.

Guess: all stones are connected (by being adjacent)

I meant to ask earlier, but I don’t think you were online at the time. Is your code repository hosted somewhere? I’d be happy to submit a pull request rather than hosting the edited code myself if you prefer.

The repository is hosted on GitHub, but I’ve never done anything collaborative on GitHub and I’m probably doing lots of things weirdly… Please feel free to continue building on your version of the tool, maybe I’ll learn how to use GitHub properly another day ^^

Interesting, so black and white are not the same!

Rule: Koans need to have an even number of black stones

I wonder if black stones can only be on the board if white stones are also on the board in a particular arrangement in relation to those black stones.

Guess: Either there are no black stones, or some must be adjacent to white stones.

Rule: there is a corner of the board, such that the centre of each black stone is contained in the convex hull of the centres of the white stones and said corner.
