Go
Not sure if this is right...maybe others here on A2K could help. I think it could be a variation of the east Asian (and worldwide) game called 'Go', A variation of 'Go' here in USA is called 'Pente.'
Go is played on a grid with black painted lines (usually 19 by 19 of them). The playing pieces, called "stones", are played on the intersections of the lines.
