Men's lacrosse is a contact game played by ten players: a goalie, three defensemen, three midfielders and three attackmen. The object of the game is to shoot the ball into the opponent's goal. The team scoring the most goals wins.

Each team must keep at least four players, including the goalie, in its defensive half of the field and three in its offensive half. Three players (midfielders) may roam the entire field.

Collegiate games are 60 minutes long, with 15-minute quarters. Generally, high school games are 48 minutes long, with 12-minute quarters. Likewise, youth games are 32 minutes long, with eight-minute quarters. Each team is given a two-minute break between the first and second quarters, and the third and fourth quarters. Halftime is ten minutes long.

Teams change sides between periods. Each team is permitted two timeouts each half. The team winning the coin toss chooses the end of the field it wants to defend first.

Attack:
The attackman's responsibility is to score goals. The attackman generally restricts his play to the offensive end of the field. A good attackman demonstrates excellent stick work with both hands and has quick feet to maneuver around the goal. Each team should have three attackmen on the field during play.

Midfield:
The midfielder's responsibility is to cover the entire field, playing both offense and defense. The midfielder is a key to the transition game, and is often called upon to clear the ball from defense to offense. A good midfielder demonstrates good stick work including throwing, catching and scooping. Speed and stamina are essential. Each team should have three midfielders on the field.

Defense:
The defenseman's responsibility is to defend the goal. The defenseman generally restricts his play to the defensive end of the field. A good defenseman should be able to react quickly in game situations. Agility and aggressiveness are necessary, but great stick work is not essential to be effective. Each team should have three defensemen on the field.

Goal:
The goalie's responsibility is to protect the goal and stop the opposing team from scoring. A good goalie also leads the defense by reading the situation and directing the defensemen to react. A good goalie should have excellent hand/eye coordination and a strong voice. Quickness, agility, confidence and the ability to concentrate are also essential. Each team has one goalie in the goal during play.

Women's lacrosse is a non-contact game played by 12 players: a goalkeeper, five attackers and six defenders. The object of the game is to shoot the ball into the opponent's goal. The team scoring the most goals wins.

Women's lacrosse begins with a draw, which is taken by the center position. The ball is placed between two horizontally held crosses (sticks) at the center of the field. At the sound of the whistle, the ball is flung into the air as the crosses are pulled up and away. A draw is used to start each half and after each goal, and it takes place at the center of the field.

The collegiate game is 60 minutes long, each half being 30 minutes. The high school girl's game is 50 minutes long, each half being 25 minutes. In both collegiate and high school play, teams are allowed one timeout per half.
