Go (碁), or Igo (囲碁) is a really, really, really really old Asian game which uses shiny black and white stones (not to be mistaken for candy, such as Mentos) on a grid-like board called a Goban (碁盤). The game is too complicated to explain here to ever play, so, like chess, most people just buy the game and store it under their pile of Xbox games.
