If you’re doing things on graphs, potentially supporting hex boards, there’s other go variants or Go inspired games one could think of also like
- hex go (go on a hexagonal board)
- trigo (two moves per player on a hex board, except Black plays one stone on the first move)
- Blooms (hex board, but two colors per player, and the objective is N captures. Place one or two stones each turn but of different colors. First player places only one stone)
- Keil (hex board, but connections are not just being adjacent, it’s about having mutually adjacent points that don’t contain the other player color)
- Redstone (normal grid but captures are redstones, no passing, capture all opponents stones to win)
