Paper soccer (or paper hockey) is an abstract strategy game played on a square grid representing a soccer or hockey field. Two players take turns extending a line representing the position of a ball until it reaches one of the grid's two-goal spaces. A traditional paper-and-pencil game, it is commonly played in schools[1] and can be found in some magazines. Many computer implementations of the game also exist. Despite the game's simple rules, paper soccer has various expanded strategies and tactics. [wikipedia] - en.wikipedia.org/wiki/Paper_soccer
