Roller hockey, rink hockey or quad hockey is a team sport played on roller skates. It is a quad-skate team sport where two teams face-off against one another, trying to drive a hard ball with their sticks into the opposing teams' goalnet. Each team has five players on the rink at a time, four of whom are skaters and one who is the goalkeeper. The ball can only be put in motion by a stick, not the skate, otherwise a foul will be stated. The game has two 25-minute halves, with 15-minute halftime intermission, plus up to two 5-minute golden goal periods to settle ties with the clock stopping when the ball becomes dead. If the tie persists, a penalty shootout will determine the winner. Players – including the goalie – use quad skates, whereas inline skates are used in inline hockey. The sticks are similar to those in bandy and shinty. Excessive contact between players is forbidden in rink hockey, unlike inline hockey.

Roller in-line hockey, American roller hockey or inline hockey, is a variant of hockey played on a hard, smooth surface, with players using inline skates to move and ice hockey sticks to shoot a hard, plastic puck into their opponent's goal to score points. The sport is a very fast-paced and free-flowing game and is considered a contact sport, but body checking is prohibited. There are five players including the goalkeeper from each team on the rink at a time, while teams normally consist of 16 players. There are professional leagues, one of which is the National Roller Hockey League (NRHL). While it is not a contact sport, there are exceptions, i.e. the NRHL involves fighting.
