Basketball is a team sport in which two teams of five active players each try to score points against one another by propelling a ball through a 10 feet (3 m) high hoop (the goal) under organized rules. Basketball is one of the most popular and widely viewed sports in the world. Points are scored by shooting the ball through the basket from above; the team with more points at the end of the game wins. The ball can be advanced on the court by bouncing it (dribbling) or passing it between teammates. Disruptive physical contact (fouls) is not permitted and there are restrictions on how the ball can be handled (violations). Through time, basketball has developed to involve common techniques of shooting, passing and dribbling, as well as players' positions, and offensive and defensive structures. Typically, the tallest members of a team will play center, the shortest member usually plays "point" while often the best ball handlers are guards.
