Curling is once again taking a close look at itself at a time when technical precision and competitive fairness are under constant scrutiny. In this context, World Curling has taken a decisive step by introducing a new Sweeping Technique Policy, a measure designed to preserve the essence of the sport and provide a clear framework on which sweeping effects are acceptable in competition.

The decision, taken in direct consultation with the World Curling Athletes’ Commission, responds to a debate that has intensified in recent years: to what extent the evolution of technique and equipment can alter the natural behavior of the stone. The objective is to protect the integrity of the game without hindering its development, by establishing precise limits that all teams can understand and respect.

Defining acceptable sweeping to protect the game

The new policy establishes that the permitted effects of sweeping are limited to two fundamental actions: making the stone travel farther and keeping it straighter, while allowing only a moderate enhancement of the natural curl. This definition seeks to refocus sweeping on its traditional role, avoiding manipulations that artificially transform the stone’s behavior on the ice.

With this clarification, World Curling aims to create consistency across different competitions and ice conditions, offering athletes and coaches a common technical framework. The measure also reflects concern for the perception of the sport, where skill, ice reading and decision-making should prevail over techniques that excessively alter the outcome of a shot.

Prohibited techniques and a more active officiating role

Within the policy, techniques that are now expressly prohibited are detailed, particularly those used with the intention of slowing a stone. Among them are single sweeping strokes using a pushing motion, whether in standard or blade orientation, as well as techniques in which the brush remains on the ice while returning to its original position or is lifted before completing the motion.

These actions, along with other similar practices, have been deemed contrary to the Statement of Principles of the sport when their purpose is to increase the deceleration of the stone. To reinforce compliance, officials have been granted greater authority: they may remove the delivered stone from play after an official warning, underscoring the importance of stricter control at the highest competitive level.
