A bowling league is a group event where several teams bowl against each other over the course of a season. Most bowling leagues consist of four team players that meet up once a week or once every other week, usually at the same day and time. Teams of three or five players are also common. Leagues can be set up as male-only, female-only, or mixed. Four-person teams tend to be used in mixed leagues, while three- and five-player teams are more common in male-only and female-only leagues.
