While most often played as a team sport with five players on each side, three - on - three, two - on - two, and one - on - one competitions are also common . The objective is to shoot a ball through a hoop 18 inches (46 cm) in diameter and 10 feet (3.048 m) high that is mounted to a backboard at each end of the court . The game was invented in 1891 by Dr. James Naismith . </P> <P> A team can score a field goal by shooting the ball through the basket being defended by the opposition team during regular play . A field goal scores three points for the shooting team if the player shoots from behind the three - point line, and two points if shot from in front of the line . A team can also score via free throws, which are worth one point, after the other team is assessed with certain fouls . The team with the most points at the end of the game wins, but additional time (overtime) is mandated when the score is tied at the end of regulation . The ball can be advanced on the court by passing it to a teammate, or by bouncing it while walking or running (dribbling). It is a violation to lift, or drag, one's pivot foot without dribbling the ball, to carry it, or to hold the ball with both hands then resume dribbling . </P>
