Indoor lacrosse is a version of lacrosse played, unlike other varieties of lacrosse, in winter in ice hockey arenas (a floor for lacrosse is placed over the ice). Indoor lacrosse was intended to be less violent than the other indoor version of the game, box lacrosse, on which it is based. Although the rules of box lacrosse have since been changed to reduce the violence in the game, some differences remain. For example, indoor lacrosse does not allow crosschecking – hitting another player with the stick with one's hands apart on the shaft – in any circumstances and allows only metal sticks with hollow shafts (box lacrosse allows solid wooden sticks). These differences allow more running than in box lacrosse.
In North America, however, indoor lacrosse is chiefly played by box lacrosse players. Box lacrosse is a summer game, while indoor lacrosse is played in the winter, so the players simply change codes. Indoor lacrosse is also played in regions where box lacrosse is not played.
Lacrosse is a team sport played by two teams of ten players each who use netted sticks (called crosses in French) in order to project a small rubber ball into the opponents' goal.
Designating lacrosse as an official sport is more of a nod to history than a reflection of the present-day situation, because very few people in Canada actually play or follow lacrosse, certainly far fewer than follow or play hockey, football, baseball, basketball, soccer, tennis, golf and other sports.
It was intended to be less violent than box lacrosse, although changes in box lacrosse rules have reduced some of its violent play and a change in indoorlacrosse rules to permit crosschecking (hitting another player with the stick with one's hands apart on the shaft) have made it more violent.
