A team sport open to male and female athletes with a physical disability in their lower limbs, it is played on an ice rink: the athletes throw the stone, a block of polished granite weighing about 20 kg, from a wheelchair positioned near the centre line. The aim is to get the stones as close as possible to the centre of a series of concentric circles. The throw can be performed through the movement of the athlete's hand or through a stick. The use of a broom in the normal phases of play is not permitted.
