roller hockey
One or more rinks for hockey played on four-wheeled roller skates, with goals at both ends.
A roller hockey facility is a place with one or more rinks or courts with a smooth, hard surface designed for hockey played on four-wheeled roller skates. Roller hockey is a team sport in which players wearing skates try to shoot a ball into a netted goal at the opposing team's end using a long stick with a flat blade at its end.
The skates have four wheels arranged at the corners rather than along a single line. This quad-skate arrangement distinguishes the game from inline hockey.
The smooth, hard rink is used by players on quad skates. Inline hockey uses skates whose wheels form a single line, while ice hockey uses an ice surface. The four-corner wheel arrangement and ball distinguish the roller hockey game described here.
