Line of the Ball
Plays are based on the “Line of the Ball,” or LOB, an imaginary line created by the ball as it travels down the field. It represents a “Right of Way” for the last player striking the ball, and is the basis for most fouls in the game. Players may try to hook or “ride-off” their opponents in an effort to gain control of the ball.
At the start of the game, team members line up in numerical order, opposite the opposing team. An umpire rolls the ball between the teams and the match begins. Play is continuous throughout the chukker, unless the umpire blows the whistle for a foul or there is any injury to a player or horse. If a penalty is called, the team fouled will have an opportunity to execute a penalty shot.
