Curling is not just any sport but rather a sport with a definite mindset. Fairness and a friendly manner are equally as important as the athletic requirements such as dexterity and skill. Curling is a sport rich in tradition. To watch a masterfully played stone is a feast for the eyes; even better though, is to witness how the century-old code, in which the true spirit of curling can be found, is observed.
Curling is played to win, but never to humiliate an opponent. A real curler prefers a loss to an unfair win! A good curler never attempts to distract or deter the opponent from giving his best. No curler ever deliberately breaks the rules or any of the written or unwritten traditions. Should this occur and the curler realizes it, he is the first to admit his mistake.
While curling consists of a two-way game of measuring dexterity and skill, the game demands of each participant an intrinsic spirit of sporting fairness as well as friendly and honourable conduct. This “spirit of curling” should be as relevant for the interpretation and application of the rules as for the comportment on and off the ice. (Source: www.curling.ch)
