The Playing Surface
The specific playing surface upon which a curling game is played.
We have four sheets on our rink.
The area between the back line and the hog line containing the target rings(the house).
Any stone that stops outside this area is removed from play.
The line across the ice at the back of the in-play area.
Stones which are completely over this line are removed from play.
The center circle of the house.
The footholds at each end of the ice from which the stone is delivered.
The line across the ice at the front of the in-play area.
Stones that do not cross the hog line are removed from play.
(unless it touches another stone that is already in play).
The target circular rings at each end of the sheet (also called the rings).
The line across the ice through the center of the target area.
