The following rules are an abbreviated version of the rules in the Official NADA Rule Book.
- The Team: Teams will be made up of 6-10 players. Six (6) players will compete on a side; others will be available as substitutes. Substitutes may enter the game only during timeouts or in case of injury.
- The Field: The game may be played indoors or outdoors. The playing field shall be a rectangle, divided into two (2) equal sections by a center line and attack-lines 3 meters from, and parallel to, the center line. (Ideal measurements are 60’ x 30’ – identical to a volleyball court.)
- The Equipment: The official ball used in tournament and league play will be an 8.25" rubber-coated foam ball.
The object of the game is to eliminate all opposing players by getting them "out." This may be done by:
- Hitting an opposing player with a LIVE thrown ball below the shoulders.
- Catching a LIVE ball thrown by your opponent before it touches the ground.
Definition: LIVE: A ball that has been thrown and has not touched anything, including the floor/ground, another ball, another player, official or other item outside of the playing field (wall, ceiling, etc.).
During play, all players must remain within the boundary lines. Players may leave the boundaries through their end line only to retrieve stray balls. They must also return through their end line.
Game begins by placing the dodgeballs along the center line – three (3) on one side of the center hash and three (3) on the other. 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. Teams may only retrieve the three (3) balls to their right of the center hash. Once a ball is retrieved, it must be taken behind the attack-line before it can be legally thrown.
Timing and Winning
The first team to legally eliminate all opposing players within the 3-minute time limit will be declared the winner. If neither team has been eliminated at the end of the 3 minutes, the team with the greater number of players remaining will be declared the winner. In the case of a tie, a 1-minute sudden death overtime will occur. The first team to knock a player out wins.
Time-Outs & Substititutions
Each team will be allowed one (1) 30-second tim-eout per game. At this time, a team may substitute players into the game. Players may also substitute into the game in case of injury.
In order to reduce stalling, a violation will be called if a team in the lead controls all six (6) balls on their side of the court for more than 5 seconds. This also applies to tied teams.
During multi-game tournaments, rules will be enforced primarily by the "honor system."* Players will be expected to rule whether or not a hit was legal or whether they were legally eliminated. All contests will be supervised by a court monitor.* The court monitor will rule on any situation in which teams cannot agree. THE COURT MONITOR’S DECISION IS FINAL – NO EXCEPTIONS.
*NOTE: During tournament play, all semifinal and final round matches will be officiated by no less than three (3) officials. These officials will rule on all legal hits, out-of-bounds and 5-second violations.
