Roller Hockey
Roller hockey  is a form of hockey  played on a dry surface using wheeled skates. [1]   The term "Roller hockey" is often used interchangeably to refer to  three variant forms chiefly differentiated by the equipment used:  traditional " Roller hockey " (Quad hockey, Rink hockey), played with quad skates  and a ball (without contact), " Inline hockey ", played with inline skates  and puck  (without contact) and " Skater hockey ",  played with quad skates or inline skates and plastic ball (with contact  like ice hockey).  Most professional inline hockey games take place on  an indoor or outdoor sport court (a type of plastic interlinking tiles  used to create a skating surface).  Otherwise, any dry surface can be  used to host a game, typically a roller rink, macadam (asphalt), or  cement. Combined, roller hockey is played in nearly 60 countries  worldwide. [2] [3]
