Part 1. The Game

Rule 1.1 Types of Games. Four-wall handball may be played by two, three or four players. When played by two, it is called singles; when played by three, cutthroat; and when played by four, doubles.

Rule 1.2 De******ion. Handball is a competitive game in which either hand or either fist may be used to serve and return the ball.

Rule 1.3 ******ive. The ******ive is to win each rally by serving or returning the ball so the opponent is unable to keep the ball in play. A rally is won when one player is unable to return the opponent's shot to the front wall before it touches the floor twice, or when a player returns the ball so that it hits the floor before striking the front wall.

Rule 1.4 Points and Outs. Points are scored only by the serving side when it serves an ace (unreturnable serve) or wins a rally. When the serving side loses one rally in singles or two rallies in doubles, it loses the serve. Losing the serve is called an "out."

Rule 1.5 Game, Match, Tie Breaker. A match is won by the first side winning two games. The first two games of a match are played to 21 points. In the event each side wins a game, a tie-breaker is played to 11 points.

In the absence of line judges, if both players in singles or three out of four in a doubles match disagree with a call made by the referee, the referee should consider reversing his call.

1. Spectators. The referee shall have jurisdiction over the spectators, as well as the players, while the match is in progress.

C. Protests. Any decision involving a rule's interpretation may be protested before the next Serve. It will then be resolved by the head referee or Tournament Director.

This applies to the start of the match, between-game time-outs, time-outs during a game and glove-change time-outs. Players should stay within earshot of the referee to help prevent the delay-of-game penalty. It is the obligation of the players to be ready to resume play on time even if the referee fails to give time warnings. If the matches are on, or ahead of, schedule, the players must be in the court warming up at least 10 minutes before the assigned match time to assure a prompt start. If running behind, the players must be dressed and ready to enter the court for a maximum 10-minute, in-court warm up.
If a player shows up less than 10 minutes before the scheduled starting time, his warm-up time will be reduced accordingly. The Tournament Director may permit a longer delay if circumstances warrant.

B. Duties and Responsibilities. Linesmen are designated to help decide appealed calls. In the event of an appeal, and after a very brief explanation of the appeal by the referee, the linesmen must indicate their opinions of the referee's call. The signal to show agreement with the referee is arm extended with thumb up; disagreement is shown by thumb pointing down. The signal to show no opinion or that the line judge is unsure or his view was blocked is arm extended with an open hand and palm down. Line judges should not signal until the referee acknowledges the appeal and asks for a ruling.
C. Result of Response. If both line judges signal no opinion, the referee's call stands. If both line judges disagree with the referee, the referee must reverse his ruling. If only one line judge disagrees with the referee's call, the referee may let the call stand, reverse his call or call for a replay.

Rule 3.6 Appeals
A. Appealable Calls. The server may appeal a short or other service fault. He may also appeal receiving line violations. If his appeal is upheld, the server is awarded the serve over. If he had one short, the call would cancel the previous fault call, and he would be awarded two serves, because he was judged to have made a legal serve. If, in the opinion of the referee, the ball could not have been returned, a point shall be awarded the server. If the appeal is not upheld, the call would be two shorts, a side out. After the rally has ended, either player may appeal on a double-bounce call or non-call, kill shots called good, kill shots called no good and court hinders. The outcome may result in a point being awarded, a side out, or a replay depending on the linesmen's opinions. If both linesmen disagree with the referee's call or non-call, the call is reversed or replayed. After the rally has ended, the receiver may appeal faults and skip serves not called. If he wins the appeal, he is awarded the appropriate call. After the rally, either player may appeal a double-bounce call or non-call, kill shots called good or no good, or any call or non-call regarding a legal return. The outcome of the appeal may result in a point or sideout being upheld, reversed or replayed, depending on the linesmen's opinions.
At no time may a player appeal a screen serve, hinder (other than court hinders), technicals or other discretionary calls.
B. How to Appeal. A player must make appeals directly to the referee before the referee announces the score. The referee will then request the opinion of the linesmen. The referee may also appeal to the linesmen himself if he is uncertain of his own call, and may then maintain, reverse or nullify his own call. A replay shall be called if the referee believes it is necessary in the interest of fairness.

Rule 3.7 Scorers. The scorer, when utilized, shall keep a record of the progress of the game in the manner prescribed by the committee or Tournament Director. As a minimum, the progress record shall include the order of serves, outs, and points.

Rule 3.8 Floor Manager. The Floor Manager informs players of their court assignments and times.
Part 4. Play Regulations

Rule 4.1 Serve.
A. Order. The player or side winning the toss of a coin chooses to serve or receive in the first game. The other player or side shall choose for the second game. If a tie breaker is necessary, the player or team scoring the higher total of points in the first two games shall choose. If both players or teams score an equal number of points in the first two games, another coin toss will be made to d determine which player or team has the choice.
B. Start. Games are started by the referee announcing the score, "0-0," and then "Play ball."
C. Place. The server may serve from anyplace in the service zone. No part of either foot may extend beyond the outer edge of either line of the service zone. Server must remain in the service zone until the served ball passes the shortline. Violations are called "footfaults" (See Rule 4.3 B.1.).
D. Manner. The server must come to a complete stop in the service zone before beginning the serve. The serve is begun by bouncing the ball to the floor in the service zone. Although the server may bounce and catch the ball several times before serving, when actually beginning the serve the ball must be struck on a single bounce. If a player allows the ball to bounce more than once after a single drop before hitting it, a "fault" will be called (See Rule 4.3 B.8). The ball must be struck by the server's hand or fist so that it hits the front wall first and on the rebound hits the floor behind the short line, either with or without touching one of the side walls. If the server bounces the ball outside the service zone as he begins his serve, a "fault" will be called (See Rule 4.3 B.7).
E. Time. A serve may not be made until the referee has announced the score. The referee shall call "point" or "side out" as soon as a rally ends. The receiver then has up to 10 seconds to assume a receiving position. When the receiver has assumed a receiving position or 10 seconds have elapsed, whichever occurs first, and the server has had reasonable time to get to his serving position, the referee shall announce the score and the server must serve (strike the ball) within 10 seconds.
If the first serve results in a fault, the referee shall give the defensive player a reasonable time to take a receiving position and then the referee shall announce "second serve," after which the server must serve within 10 seconds.

Rule 4.2 Doubles.
A. Server. At the beginning of each game in doubles, each side informs the referee of the order of service, which must be followed throughout the game. Only the first server on the first serving team may serve the first time up. This player must continue to serve first throughout the game. When the game's first server is put out on his initial serve, the side is out. Thereafter, both players on each side shall serve until an out for each occurs. It is not necessary for the server to alternate serves to the opponents.
B. Partner's Position. On each serve, the server's partner shall stand erect with his back to the side wall and with both feet on the floor within the service box until the served ball passes the short line. Violations are called "foot faults."

Rule 4.3 Defective Serves. Defective serves are of three types and result in penalties as follows:
A. Dead-Ball Serves. A dead-ball serve results in no penalty and the server is given another serve without canceling a prior illegal serve. This occurs when an otherwise legal serve:

1. Hits Partner. Hits the server's partner on the fly on the rebound from the front wall or from the front wall and a side wall while the server's partner is in the service box. Any serve that touches the floor before hitting the partner in the box is a fault.
2. Screen Balls. If, in the referee's judgment, the ball passes so close to the server or the server's partner that the receiver's view of the ball is obstructed, a screen should be called. Any otherwise legal serve that passes behind the server's partner, between the partner and the side wall, is an automatic screen.
3. Straddle Balls. A legally served ball that travels between the legs of the server is an automatic screen.
4. Court Hinder. If a served ball takes an erratic bounce due to a court obstruction or wetness, a court hinder is called and the serve is replayed.
5. Broken Ball. If the ball is determined to have broken on the serve, a new ball shall be substituted and the serve shall be replayed, not canceling a prior fault.

B. Fault Serves. The following serves are fault serves and any two that are hit before a legal serve is executed result in an out:
