Open-gym basketball involves players getting together for pick-up play at school, church or a rec center court. Officials are not involved; players are responsible for calling their own fouls. Contests are typically played to a designated point total, with no game clock.
Depending on the number of players that show up, the winning team generally stays on the court, while a new team waits on the sideline for the next game. While there are typically no restrictions on those attending, many open gyms tend to attract players of similar ability. Some organized events may require players pay a small fee to cover the cost of gym rental.
Other open gyms may be organized by coaches to scout potential players for their AAU or other travel team. College teams and prospective walk-ons often participate in open-gym play during the off-season when restrictions prohibit organized team practices.
