What is the last stone advantage called in curling?
Having the hammer means your team can throw the last stone in an end, making it much easier to score at least a point and win the end. After a team scores, the hammer will switch to the other team to even the playing field.
In professional championship curling, it is decided by who can throw a rock closest to the middle before the game starts. In general recreation curling, it is often decided by a simple coin flip or rock paper scissors.
