Centerline: The line running parallel to the long end of the ice along the middle of the sheet. This line divides the sheet into two, symmetric parts.

Sidelines: The lines running parallel to the long end of the ice at the outer ends of the sheet. If a stone touches one of these lines, it is out of play.

Backlines: The lines running parallel to the short end of the sheet that just touch the back end of the house. If a stone fully crosses these lines, it is out of play.

Stone: The object that is thrown in curling. Each one weighs about 42 pounds and is made of granite from Ailsa Craig, an island in Scotland.
