Here the tiles have been rotated to favor white. The long chain of white stones is decorated with an intense green. Smaller chains are decorated with fainter green.


It may look like that long chain is actually two chains, but the board is really a torus, so the top tiles are neighbors to the bottom tiles, and left tiles neighbors to the right tiles. So, to form the long chain, the top, right tile touches the bottom, right tile on a light edge.
