In many North American minor leagues, the player that scores the shootout-winning goal is credited with one shot on goal and one goal. The losing goaltender of the shootout is credited with one shot against, one goal against, and an overtime/shootout loss. North American professional hockey does not allow shootouts in post-season play, and instead will play multiple 20-minute sudden-death overtime periods as are needed until a team scores. The official IIHF name of the procedure is game-winning shots (GWS). In some European countries, the post-game penalty shots are unofficially known as "bullets".
