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.
The first World Indoor Lacrosse Championships were held in 2003. The competitors were national teams of Australia, Canada, the Czech Republic, the Iroquois Nation, Scotland, and the United States. Canada defeated the Iroquois Nation in the final by a score of 21-4.
