Hockey is where two teams compete by trying to maneuver a hard, round ball or a puck into the opponent's goal, past the goalkeeper or goaltender, using a stick.

Field hockey and ice hockey both developed independently from an earlier form of the game. The dominant form in any region is usually referred to simply as hockey, with the less popular forms given more detailed names. Thus hockey on its own refers to field hockey in most countries, but to ice hockey in countries such as Canada, Russia, the USA and Scandinavia where ice hockey is more commonly played. The Olympic Movement refers to "hockey" as a summer sport and "ice hockey" as a winter sport.
