The game consists of four to eight 7 minute chukkas, between or during which players change mounts. At the end of each 7 minute chukka, play continues for an additional 30 seconds or until a stoppage in play, whichever comes first. There is a four minute interval between chukkas and a ten minute halftime. Play is continuous and is only stopped for penalties, broken tack equipment or injury to horse or player. The object is to score goals by hitting the ball between the goal posts, no matter how high in the air. If the ball goes wide of the goal, the defending team is allowed a free knock in from the place where the ball crossed the goal line, thus getting the ball back into play.
