The field of play  curling ice

Curling is played on a very long strip of specially prepared ice called a sheet. A sheet of curling ice is over 45 metres long and a maximum of five metres wide. At each end of the sheet there are two circles that look like target, known as houses. Each house consists of four rings which help define which curling stones are closest to the centre, commonly known as the Button.


Most curling clubs have an ice maker whose main job is to care for the ice. A key part of the preparation of the playing surface is the spraying of water droplets onto the ice, which form pebble on freezing. The pebbled ice surface resembles an orange peel, and the stone moves on top of the pebbled ice. The pebble, along with the concave bottom of the stone, decreases the friction between the stone and the ice, allowing the stone to travel farther. As the stone moves over the pebble, any rotation of the stone causes it to curl, or travel along a curved path. 





The process of sliding a stone down the sheet is known as the delivery or throw. The stone is delivered either by hand or may be aided by the use of delivery sticks (called 'extender'). Players must release the stone before the Hog Line for the stone to be considered in play. Unlike the pedestrian curling, wheelchair curlers do not slide from the Hack to the Hog Line. They deliver the stone stationary. The other big difference is that there is no sweeping.




A team consists of 5 players and the coach. 4 of the 4 players are on the ice, the 5th player is a substitute player. The coach trains and leads the team, but during competition he is only allowed to coach the team on the ice during half time or a time-out. A time-out can only be chosen by the team. Unlike pedestrians, wheelchair curlers must have a mixed team, i.e. at least one woman or man must play in the team.


Each player delivers 2 stones per end. In contrast to the pedestrian curling a whole game lasts only 8 ends. If the game is a draw after 8 ends, additional ends are played until the decision is made.
