The object of the game is to use a lacrosse stick, or crosse, to catch, carry, and pass a solid rubber ball in an effort to score by shooting the ball into the opponent's goal. The triangular head of the lacrosse stick has a loose net strung into it that allows the player to hold the lacrosse ball. In addition to the lacrosse stick, players are required to wear a certain amount of protective equipment. Defensively the object is to keep the opposing team from scoring and to dispossess them of the ball through the use of stick checking and body contact. The rules limit the number of players in each part of the field. It is sometimes referred to as the "fastest sport on two feet".
