Hockey

Hockey is a family of sports in which two teams play against each other by trying to maneuver a ball or a puck into the opponent's goal using a hockey stick. 


FIELD HOCKEY.
Field hockey is played on gravel, natural grass, sand-based or water-based with a small, hard ball. Hockey has several regular international tournaments for both men and women. These include the Olympic Games, the Commonwealth Games, the quadrennial Hockey World Cups, the annual Champions Trophies and World Cups for juniors. 


ICE HOCKEY.
Ice hockey is played on a large flat area of ice, using a three-inch-diameter rubber disc called a puck. This puck is often frozen before high-level games to decrease the amount of bouncing and friction on the ice. The game is contested between two teams of skaters. The game is played all over North America, Europe and in many other countries around the world to varying extent. It is the most popular sport in Canada, Finland, Latvia, the Czech Republic and in Slovakia. 


INLINE HOCKEY.
Inline hockey is a variation of Roller hockey and Ice hockey. Inline hockey is played by two teams, consisting of four skaters and one keeper, on a dry rink divided into two halves by a center line, with one net at each end of the rink. The game is played in three 15-minute periodes with a variation of the ice hockey off-side rule.


ROLLER HOCKEY.
Roller hockey, also known as quad hockey, international-style ball hockey, and Hoquei em Patins is an overarching name for a roller sport that had existed since long before inline skates were invented. This sport is played in sixty countries and has a worldwide following. Roller hockey was a demonstration sport at the Barcelona Summer Olympics in1992.
