Two players, Cross and Parallel, take turns placing a stone of either color at a vacant board point. Cross wins by connecting all four sides with a chain of either color. Parallel wins by connecting either the top and bottom or left and right sides with two chains, one of each color. Draws are not possible. The game can be played on Richard's PBeM server: http://www.gamerz.net/pbmserv/jade.html
