Gomoku and Renju is actually two strategy games, very similiar, on one cartridge. I don't know what the exact difference between the two is, but basically, you take turns (against the computer) placing your pieces on a grid. The first person to get 5 lined up of their own color (can be horizontally, vertically, or diagonally), wins.
Please note:The intro screen uses a semi-graphics mode that does NOT display properly on a Coco 3... but the game itself works fine.
