Roller hockey is a form of hockey played on a dry surface using skates with wheels. The term "Roller Hockey" is often used interchangeably to refer to two variant forms chiefly differentiated by the type of skates and sticks used. There is traditional "Roller hockey", played with quad roller skates, and "Inline Hockey", played with inline skates. Combined, roller hockey is played in nearly 60 countries worldwide, Benfica being the only club to practice it without interruption.
Similarities and differences between Roller Hockey (Quad) and Roller Hockey (Inline) 
Roller Hockey played on Quad skates and Roller Hockey played on Inline skates have different rules and equipment, and they involve different types of skating but share the name Roller Hockey. Roller hockey (Quad) is played using traditional quad roller skates, affording greater maneuverability to the player - this results in games filled with fancy footwork, tight maneuvering, and is more similar to football or basketball. The stick is more or less the same as in bandy and shinty. Roller Hockey (Inline) bears close resemblance to ice hockey and is played on Inline skates, uses an ice hockey stick and includes a lot of fast "racing back and forth" action. The Roller Hockey (Inline) Goalie uses a Glove, called a catcher, to catch the shot on goal, he also has a flat, usually square, mit which is used to deflect the shot this is called a blocker. The Roller hockey (Quad) Goalie uses a flat batting glove that provides rebound characteristics when blocking a shot on goal.
Roller hockey (Quad) 
Roller Hockey (Quad) is a variation of roller hockey. Roller Hockey is the overarching name for a rollersport that has existed long before inline skates were "re-invented" in the 70s (They were actually invented before quads, in the 1760s). Roller Hockey has been played on quad skates, in sixty countries worldwide and so has many names worldwide. Sometimes the sport is called Quad Hockey, Hóquei em Patins (PT), Rolhockey (NL), Rollhockey (DE), International Style Ball hockey, Rink Hockey (FR), Hockey Su Pista (IT), Hoquei sobre Patins (CA), Hockey sobre Patines (ES), Rulleskøjtehockey (DA), Rullbandy (S), Rulluisuhoki (ET) and Hardball hockey (US), depending on which region of the world it is played. Roller hockey was a demonstration rollersport in the 1992 Summer Olympics in Barcelona.
Roller hockey (Inline) 
Roller hockey (Inline) is a variation of roller hockey very similar to ice hockey, from which it is derived. The game is played by two teams, consisting of four skaters and one goalie, on a dry rink divided into two halves by a center line, with one net at each end of the rink. When played more informally, the game often takes place on a smooth asphalt surface outdoors. The game is played in three 15-minute periods or if it is higher standard it's played 20-minutes in each of the three periods. The game rules differ from ice hockey in a few simple ways: there is no icing or body checking and it is played in a 4 on 4 player format instead of 5 on 5. Like ice hockey, roller hockey (Inline) is a contact sport. It is similar to ice hockey in that team work, skill and aggressiveness are needed. Excepting the use of inline roller skates in lieu of ice skates, the equipment of inline roller hockey is similar to that of ice hockey. Roller Hockey (Inline) is referred to by many names worldwide, including Ball Hockey, Inline hockey, Roller Hockey, Longstick hockey, Deck hockey, Road hockey, Street hockey and Skater hockey depending on which region of the world in which it is played. Generally speaking, only competitive level Inline hockey is strictly bound by the governing body's rules. Recreational hockey leagues may make modifications to certain aspects of the rules to suit local requirements (size of rink, length of periods and penalties). Roller hockey is a growing sport in Britain with teams cropping up all over the country. The fact that it can be played on any dry surface means that you can play it in almost any leisure center.
