Two teams, each team gets 5 players per round

Substitutions may be made between rounds only

Each team may set their own formations but there must be at least 3 players within 10 yards of the dividing line

Players must never cross the dividing line

To eliminate a player you must hit him with a thrown ball below the shoulders or catch a ball he has thrown

Note: If a player ducks, and this is clearly the cause for the player being hit above the shoulders, the player is out and the throw is legal.

Once a player is hit he must sit on the sidelines for the remainder of the round

If a teammate catches an opposing player's throw he may designate one teammate who is out to return to the game

Players who hit someone in the head must sit out the current round and the following round, with no substitution

Game begins by placing the dodgeballs along the center line. Players then take a position behind their end line. Following a signal by the official, teams may approach the centerline to retrieve the balls. This signal officially starts the contest.

Rush Rule: Each and every ball retrieved at the opening rush must first be taken beyond the attack line and into the team’s backcourt before it may be legally thrown at an opponent. ( The Attack line is service line on the tennis courts.)

The first team to legally eliminate all opposing players will be declared the winner of that round; first team to win best 2 out of 3 rounds wins the match. A 12-minute time limit has been established for each match. If neither team has been eliminated at the end of the 12 minutes, the team with the greater number of players remaining will be declared the winner. In the case of an equal number of players remaining after regulation, a 3-minute sudden-death overtime period will be played.
