Leagues may be run by a group of volunteers, or the league may be run as a business. During the season, each team normally plays each of the other teams several times. This entitles you to participate in league activities, get the newsletter, if any, and sometimes get a patch, pin, or shirt with the assn. In many cases, the team fee is paid for by the sponsoring bar, that is, the pub at which the team plays darts. The bar will also often provide team shirts, imprinted with the bar logo and team name.
Some leagues also have nightly fees, or player fees.
Some leagues, called In-House Leagues, play all games at just one location. Leagues in most areas play on weekday evenings, although there are quite a few local exceptions. Play consists of a variety of games of '01 and sometimes Cricket, with Singles, Doubles, and Team matches usually played. Most leagues are split into divisions, of different skill levels, or have some sort of hanicapping system to level the field.
