Hockey is a popular sport played on ICE, and the venues for hockey games are typically referred to as rinks, arenas, or ICE. A RINK is a term used to describe a rectangular area of ICE that is used for hockey games, and it is usually surrounded by boards or walls. An ARENA is a larger venue than a RINK, and it is typically used for professional hockey games. ICE is simply the frozen surface on which hockey is played. All three terms are used to refer to the venues in which hockey is played.
