Toridal Go |

Rick and I have been playing 9x9 toroidal Go. It's pretty neat.
The idea of playing Go on the surface of a torus had been kicking
around my head for a while. In concept it's very simple -- you
need make only a small alteration to a single rule. When you
compute adjacency, treat opposing edges as connecting. For
example, the four corners of the board form a 2x2 square. This is
really hard to visualize, which is why I'd not actually taken the
trouble to play.
Over the thanksgiving break, though, I had an idea. The board is 19x19, so there's room -- with some left over -- for four 9x9 boards. If you play 9x9 Go in quadruplicate, then you can see the toroidal adjacencies and play sort of normally. It's a little annoying to have to place four pieces for every move, but you get really fast at it.
The strategey changes, though, are pretty hard to think about. I'm definitely not yet used to a world without edges.
