Bowls is an IPC Championship sport widely practiced in 15 countries. Although it is no longer included in the Paralympic Games programme, regular multi-disability World Championships are conducted. Bowls is practiced by both male and female athletes with a physical disability. The game is played on a level, grassed or synthetic surface called a green between two competitors or teams consisting of two, three or four players. The aim is to throw one's ball as close as possible to a white ball called a jack. Bowls is governed by the IPC through the International Paralympic Bowls Committee.
