5-on-5 Basketball is a Tier 1 event. Competition begins as a round robin tournament between companies of the Blue, White and Red Leagues.
Desired roster size is seven (7). Four (4) players are required to avoid a forfeit. One player from each team is designated as the team captain prior to start of play.
Start time is forfeit time: there is no grace period for players to arrive late. Two (2) game forfeits disqualify a team from further play.
Use of a women's ball is required if women are on the team roster.
Games are played in two (2) 15-minute halves with a 5-minute break between halves. Games may be shortened at the discretion of officials. One 20-minute half will constitute a complete game. The clock runs continuously until the last two (2) minutes of each half when it will stop for all fouls and time-outs. Each team is entitled to two 1-minute time-outs per half. If the game ends in a tie score, a 3-minute overtime period will be played. If a second overtime is necessary, the team scoring first wins.
Until the last two (2) minutes of each half, the ball changes possession after a personal foul. During the last two (2) minutes, a player shoots one-and-one free throws when fouled.
At any time during the game, an official may award two (2) free throw attempts for intentional fouls, technical fouls, and flagrant fouls. The offended team gets possession of the ball following the free throw attempts.
The NCAA governs all other rules.
