Lacrosse stick in the context of "Lacrosse"

Field lacrosse is a full contact outdoor sport played with two opposing teams of 10 players each. The sport originated among Native Americans, and the modern rules of field lacrosse were initially codified by Canadian William George Beers in 1867. Field lacrosse is one of three major versions of lacrosse played internationally. The rules of men's lacrosse differ significantly from women's field lacrosse (established in the 1890s). The two are often considered to be different sports with a common root. An outdoor six-a-side version, lacrosse sixes, was established in 2021 and features six players per team, reduced field size, and shorter duration to be conducive for daily tournament play. Another version, indoor box lacrosse (originated in the 1930s), is also played under different rules.

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".

Women's lacrosse (or girls' lacrosse), sometimes shortened to lax, is a field sport played at the international level with two opposing teams of ten players each (12 players per team at the U.S. domestic level). Originally played by indigenous peoples of the Americas, the modern women's game was introduced in 1890 at the St Leonard's School in St Andrews, Scotland. The rules of women's lacrosse differ significantly from men's field lacrosse. The two are often considered to be different sports with a common root.

The object of the game is to use a long-handled stick (known as a crosse or lacrosse stick) to catch, cradle, and pass a solid rubber lacrosse ball in an effort to score by hurling the ball into an opponent's goal. Cradling is a technique of moving the wrists and arms in a semi-circular motion to keep the ball in the pocket of the stick's head using centripetal force. The head of the lacrosse stick has a mesh or leather net strung into it that allows the player to hold the ball. 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 positioning. The rules of women's lacrosse are different from the men's lacrosse game. Equipment required to play is also different from the men's. In the United States, women are only required to wear eyewear or lacrosse goggles and a mouth guard. The stick has restrictions too, as it must be a certain length and the pocket must be shallow enough to show the ball above the side when held at eye level.

Box lacrosse, also known as boxla, box, or indoor lacrosse, is an indoor version of lacrosse played mostly in North America. Box lacrosse is traditionally played on an ice hockey rink once the ice has been removed or covered. The playing area is called a box, in contrast to the open playing field of field lacrosse. Box lacrosse is played between two teams of five players and one goalie each. The object of the game is to use a lacrosse stick to catch, carry, and pass the ball in an effort to score by shooting a solid rubber lacrosse ball into the opponent's goal.

The game originated in the 1930s in Canada, where it is more popular than field lacrosse.

A lacrosse ball is the solid rubber ball that is used, with a lacrosse stick, to play the sport of lacrosse. It is typically white for men's lacrosse (however the PLL uses optic yellow balls for better TV visibility), or yellow for women's lacrosse; but the balls are produced in a wide variety of colours.

The current World Lacrosse, NCAA, and NFHS approved specifications are:

Intercrosse (also called soft stick lacrosse, softcrosse, modcrosse, or pop lacrosse) is a non-contact form of lacrosse using modified lacrosse equipment. An intercrosse stick is different from a normal lacrosse stick: the head is completely plastic while the head of a traditional stick has a pocket of synthetic mesh or leather and nylon string. The ball is larger, softer, and hollow, unlike a lacrosse ball, which is solid rubber.

Intercrosse as a competitive adult sport is popular in many continental European countries, particularly in the Czech Republic, as well as in Quebec, Canada. Generally teams consist of five players per side, and the field size is 20 m wide and 40 m long. Goals are the same size as box lacrosse, 4 feet in height and width (1.2 x 1.2 m). As there is no contact allowed in the game, a player is not allowed to carry the ball for more than 5 seconds. Once it has obtained the ball a team must shoot on the goal within 30 seconds or lose possession.
