Hockey

Hockey is a family of stick sports where two opposing teams use hockey sticks to propel a ball or disk into a goal. There are many types of hockey, and the individual sports vary in rules, numbers of players, apparel, and playing surface. Hockey includes both summer and winter variations that may be played on an outdoor field, sheet of ice, or an indoor gymnasium. Some forms of hockey require skates, either inline, roller or ice, while others do not. The various games are usually distinguished by proceeding the word hockey with a qualifier, as in field hockey, ice hockey, roller hockey, rink hockey, or floor hockey.
