Rules of water polo

The rules of water polo are the rules and regulations which cover the play, procedure, equipment and officiating of water polo. These rules are similar throughout the world, although slight variations to the rules do occur regionally and depending on the governing body. Governing bodies of water polo include FINA, the international governing organisation for the rules; the NCAA rules, which govern the rules for collegiate matches in the USA; the NFHS rules which govern the rules in high schools in the USA and the IOC rules which govern the rules at Olympic events.

Core Rules

Note: Rules below reflect the latest FINA Water Polo Rules.

Number of players

Senior games consist of seven players from each team (six field players and a goalkeeper) that are allowed in the playing area of the pool during game play. FINA reduced the number of players in U20 (and younger) competitions that they sanction to six (5 field players and a goalkeeper) in 2014 with the intention of extending these changes to all levels of the game after the 2016 Olympic Games. If a player commits a major foul, then that team will play with one player fewer until the player is allowed to re-enter (typically 20 seconds). If a player commits a particularly violent act, such as striking a player, then the referee may signal a brutality foul, in which case that team is required to play with one fewer player in the water for a full 4 minutes, in addition to that player being disallowed any subsequent re-entry (i.e. he or she must sit out for the remainder of the game). In addition, the player may not be allowed to compete in a given number of future games depending on the governing body.

Players may be substituted in and out after goals, during timeouts, at the beginning of each quarter, after ordinary fouls and after injuries. During game play, players enter and exit in the corner of the pool, or in front of their goal; when play is stopped, they may enter or exit anywhere.

If at any time during play a team has more players in the pool than they are allowed, a penalty is given to the opposing team.

Caps

The two opposing teams must wear caps which contrast:

• with both (or either) goalkeeper cap color,
• with the other team's cap color and
• with the ball color.

In practice, one team usually wears blue caps and the other white, but some teams do choose to wear different cap colors. For instance, Australia's women's water polo team wears green caps.

Both goalies wear red caps. The first choice goalkeeper is usually marked "1" with the reserve being marked "13" (under FINA rules) or "1A" (under NCAA and NFHS rules).

Duration of game

The game is divided into four periods; the length depends on the level of play. There is no overtime in international water polo, and games proceed to a shoot out if a victor is required. At the collegiate level there are two straight 3-minute periods, and if still tied multiple 3-minute golden goal overtime periods thereafter. Lower levels of play have different overtime rules depending on the organization.

Game and Shot Clock

The game clock is stopped when the ball is not 'in play' (between a foul being committed and the free throw being taken, and between a goal being scored and the restart). As a result, the average quarter lasts around 12 minutes 'real time'. A team may not have possession of the ball for longer than 30 seconds without shooting for the goal unless an opponent commits an ejection foul. After 30 seconds, possession passes to the other team. However, if a team shoots the ball within the allotted time, and regains control of the ball, the shot clock is reset to 30 seconds. Each team may call 1 one-minute timeout in each period of regulation play as long as the ball is in their possession, and one timeout if the game goes into overtime. During game play, only the team in possession of the ball may call a timeout.

Pool Dimensions

The layout of a water polo pool showing the 2m and 5m markings (red and yellow), the half-way line (marked in white), a goal at either end and the length and width of the pool.

Dimensions of the water polo pool are not fixed and can vary between 20×10 and 30×20 meters. Minimum water depth must be least 1.8 meters (6 feet), but this in reality is sometimes not the case due to practicalities. The goals are 3 meters wide and 90 centimeters high. Water polo balls are generally yellow and of varying size and weight for juniors, women and men. The middle of the pool is designated by a white line. Before 2005, the pool was divided by 7 and 4 meter lines (distance out from the goal line). This has been merged into one 5 meter line since the 2005–2006 season. Along the side of the pool, the center area between the 5 meter lines is marked by a green line (if marked at all). The "five meters" line is where penalties are shot and it is designated by a yellow line. The "two meter" line is designated with a red line and no player of the attacking team can receive a ball inside this zone.

Gameplay

Moving the ball

Players can move the ball by throwing it to a teammate or swimming with the ball in front of them. Players are not permitted to push the ball underwater in order to keep it from an opponent, or push or hold an opposing player unless that player is holding the ball. If a player does push the ball underwater when it is in their possession, that will result in a "turnover" which is when you have to hand the ball over to the other team. Water polo is an intensely aggressive sport, so fouls are very common and result in a free throw during which the player cannot shoot at the goal unless beyond the "5 meter" line. If a foul is called outside the 5 meter line, the player is either able to shoot, pass or continue swimming with the ball. Water polo players need remarkable stamina because of the considerable amount of holding and pushing that occurs during the game, some allowed, some unseen or ignored by the referees (usually underwater).

Fouls

Ordinary fouls occur when a player impedes or otherwise prevents the free movement of an opponent who is not holding the ball. The most common is when a player reaches over the shoulder of an opponent in order to knock the ball away while in the process hindering the opponent. Offensive players may be called for a foul by pushing off a defender to provide space for a pass or shot. The referee indicates the foul with one short whistle blow and points one hand in the direction of the attacking team (standing roughly in line with the position of the foul), who retain possession. The attacker must make a free pass without undue delay to another offensive player. If the foul has been committed outside the 5-meter line, the offensive player may also attempt a direct shot on goal, but the shot must be taken immediately and in one continuous motion. Because of this rule the hole set will often set up at or beyond the five meter mark hoping to get a foul, shoot, and score. If the offensive player fakes a shot and then shoots the ball, it is considered a turnover. If the same defender repetitively makes minor fouls, referees will exclude that player for 20 seconds. To avoid an ejection, the hole defender may foul twice, and then have a wing defender switch with him so that the defense can continue to foul the hole man without provoking an exclusion foul. The rule was altered to allow repeated fouls without exclusions, but is often still enforced by referees.

Major Fouls

Major fouls (exclusion fouls) are committed when the defensive player holds with two hands, sinks or pulls back the offensive player away from the ball before the offensive player has had a chance to take possession of the ball. This includes dunking (sinking in FINA rules), intentional splashing, pulling back, swimming on the other player's back,stopping the other player from swimming or otherwise preventing the offensive player from preserving his advantage. A referee signals a major foul by two short whistle bursts and indicates that the player must leave the field of play and move to the penalty area for twenty seconds. The referee will first point to the player who commits the foul and will blow the whistle, then they will point to the ejection corner and blow the whistle again. The player must move to the penalty area without impacting the natural game play. If the player does not leave the field of play, the player will be kicked out for the remaining time of the game with substitution. The remaining five defenders, to cover the six attackers on a man up situation, usually set up in a zone defense in front of their goal. The attacking team can expect to score, by adopting a 4–2 or 3–3 formation, and moving the goalkeeper out of position. A player that has been ejected three times must sit out the whole match with substitution, much like the six personal fouls in basketball.

Drawing the ejection (forcing defense to commit a major foul) occurs when an offensive player takes advantage of a defensive player by using body position and/or grabbing on their wrists to make it appear as though the defensive player is committing a "major foul", therefore resulting in the ejection of that player and gaining a 6 on 5 advantage. Another common way to draw an ejection is by staggering stroke while being chased to make it appear as though the defensive player is pulling the swimmer back.

Brutality fouls A brutality is called when a player kicks or strikes an opponent or official with malicious intent. The strike must make contact with the player for a brutality to be called, and must be with intent to injure. Otherwise the player is punished with a misconduct foul, with substitution allowed after 20 seconds or a change of position. The player who is charged with a brutality is excluded from the game for 4 minutes, and the team is forced to play with one less player than the other team for that duration. In addition to the exclusion a penalty shot is also awarded to the opposing team, if the foul occurs during actual play. Previously, the team who was charged with a brutality would be required to play the remainder of the game with one less player, similar to a red card awarded in football. All brutalities have to be reported by officials and further actions may be taken by the relevant governing body. These actions could include more games added onto the one game suspension.

A misconduct foul is an unsportsmanlike act. For unacceptable language, violence or persistent fouls, taking part in the game after being excluded or showing disrespect, a player is ejected for the remainder of the game with substitution after 20 seconds has elapsed. There are two kinds of misconduct fouls that a player can incur. If a player physically assaults another player and the referee deems it not to be severe enough to warrant a charge of brutality, the lesser charge being Misconduct-Violence can be applied. If the incident does not involve physical (or attempted) contact, the referee can impose a Misconduct charge. In most competitions Misconduct-Violence carries heavier sanctions than Misconduct.

Officials

The game of water polo requires numerous officials. The four main categories are: referee, secretary, timekeeper and goal judge. These can again be qualified into two broader categories: game officials and table officials.

Game officials

The game officials in water polo are the referee (or referees) and the goal judges. Game officials are broadly responsible for ensuring the game runs smoothly and that correct and fair decisions relating to the game are made.

Referee

The referees have ultimate power over decisions relating to the game, even (if necessary) overruling decisions from goal judges, secretaries or timekeepers. They have the responsibility of signalling fouls (minor, major, brutality and misconduct), goals, penalties, timeouts, start of play, end of play (to an extent), restart of play, neutral balls, corner balls and goal throws. He or she must attempt to keep all of the rules of water polo to the governing body they are using.

There are always either one or two referees in a game of water polo. At a higher level, two referees are virtually always used, but at lower levels and/or if there are limited available referees, a referee may officiate the game without another.

Originally, referees used flags to indicate possession, but these were replaced in 1997 with hand gestures.

When goal judges are not present or available, the referee(s) my take their place in that they have the decision as to whether the ball has crossed the line etc.

When there are two referees, the ball may be called out of the water for the referees to confer about an appropriate decision and come to an agreement.

Referees have dress codes at higher (and sometimes lower) levels of water polo, and are expected to abide by this. Often, the dress code is all white, but some associations deviate this slightly.

Referee signalling

Referees have a variety of methods for signalling fouls, most of which are done by hand and with the aid of a whistle. The purpose of these signals are to inform players, coaches, spectators and other officials of the decision being made, with sometimes information as to why the decision has been awarded.

Goal judge

The goal judges are responsible for several parts of the game. These include: signalling when a goal is scored, signalling corner throws, improper re-entry (after an exclusion), to signal when play can start (at the beginning of quarters) and to signal improper restart at the beginning of quarters.

The goal judge is situated (normally sat) perfectly in line with the goal line - one at either end and usually on opposite sides. They remain seated throughout the game.

In practice goal judges are very rarely used at lower levels, but are compulsory at most international matches. Like referees, they will normally have a dress code which they are expected to abide by.

Previously, goal judges would use a red flag to indicate a corner and a white flag for a goal throw, but these have since been replaced with hand gestures.

Table officials

The table officials in water polo are the timekeeper(s) and the secretary/secretaries. They are overall responsible for the timings of the game and keeping correct information regarding the events of the game, as well as informing of the players of very specific information (notably to do with exclusions and exclusion fouls).

Timekeeper

The timekeeper (or timekeepers) have varying responsibilities depending on the equipment available. Only one is required if no 30 second clock is being used, with two being required otherwise. (Shot clocks are supposed to be used, but sometimes due to unavailability games are played without them). In higher level matches sometimes there are even more than two timekeepers used.

Often (though not always) one timekeeper is responsible for running the shot clock. This means that he or she resets it when necessary. When this is the case, the other timekeeper is often responsible for the game clock and score. If an electronic scoreboard and game clock is being used, the timekeeper will update the score when necessary, and has a similar job with the game clock. If not, then the timekeeper will manually time the periods with a stopwatch (or similar device) and alert the players when the period is over with a whistle. If an electronic scoreboard is used, a synthetically produced sound is often produced at the end of periods to alert other officials and players of the end of the period.

Timekeepers are essentially responsible for keeping record of: the current score (though this is done more officially by the secretary), the 30 second clock, the length of the quarters (at the end of each quarter they indicate this with a whistle blow if this is not done synthetically), the time of exclusion (and when re-entry is thus allowed), the length of timeouts, the length of time between periods and to signal (if not done synthetically) by whistle 30 seconds before the end of quarter or half time and 15 seconds before the end of a timeout. Timekeepers are also responsible for the last minute bell: a bell (or other device - can be audible) showing one minute remaining before full-time.
