A Fan's Guide to Water Polo
History
Water polo began in the 1870's in England. Since then, its popularity has grown, as shown by the addition of men's water polo to the Olympics in 1900 and, more recently, women's water polo in 2000.
The object of the game is to throw a ball through the opposing team's goal to score a point. The team with the most points at the end of four quarters of play wins the game.
The Essentials (Offense and Defense, Scoring)
Game Length: A game of water polo is divided into four seven-minute quarters. A game clock counts down the time left in each quarter. A shot clock, which starts at 30 seconds, counts down the time that the offense has to shoot the ball on each possession. Both clocks stop immediately following a foul and do not start until the ball is put back into play. With the clock constantly stopping, and with the breaks between quarters, you can expect a water polo game to last about an hour.
Start of the Game: At the beginning of each quarter, each team lines up on the goal line. Once the referee blows the whistle to signal the start of each quarter, the players sprint toward mid-pool, where the referee drops the ball. Whoever wins the sprint is the first to be on offense.
Offense and Defense: Players advance by swimming and passing the ball. With the exception of the goalie, they can only touch the ball with one hand at a time. Most offenses organize themselves into a similar configuration each time they prepare to score a goal. The offense surrounds the hole-set, who is positioned directly in front of the opponent's goal. Perimeter players, also known as drivers, try to take a shot at the goal or attempt a wet-pass into the hole-set - a strategy called "setting the hole". The hole-set shoots the ball if given the opportunity, but is often strategically fouled by the hole-guard, who chooses to foul the hole-set and force a free-pass, rather than allow him to shoot the ball. Immediately following a foul, there are three seconds of dead-time, in which the fouled player must put the ball in play. During dead-time, perimeter players drive towards the goal to either become available to take a shot, or 'draw a foul,' which results in the defender's exclusion form the game for 20 seconds. During the 20 second exclusion, the offensive team is in a power play that creates a high probability for scoring.
Scoring: A goal is scored once the ball completely passes over the goal line. If a goal is scored, the teams line up mid-pool and the non-scoring team takes possession of the ball.
Counter-attack and transition: The counter-attack is the transition between when the defensive team obtains possession of the ball and when it sets up in front of its opponent's goal. During the counterattack, the goalkeeper looks for an outlet to an open player down-field who either runs a fast break or sets up the offense.
Equipment: There is minimal equipment in water polo. Players wear swimsuits and caps. Additionally, there is a yellow ball and several goals The women's ball is slightly smaller than the men's ball.
Fouls
Whistles and Fouls: Water polo is a physical sport. There is considerable contact under the water. Unlike many sports where play is stopped anytime a whistle blows or a foul is called, in water polo the speed of play often increases following a whistle.
Foul Type: There are three types of fouls; ordinary, exclusion, and penalty fouls.
Ordinary Foul: Violation of minor rules. Results in free throw for fouled team. Accounts for the majority of the fouls in the game. Examples include: using two hands, impeding the movement or pushing off of an opponent, 2-meter violation, shot clock violation. Signaled by one whistle for defensive, two for offensive. Referee points in the direction ball will be played.
Exclusion Foul (Kickout): More serious violations of the rules: Often called for "playing the player, not the ball." Results in the exclusion of a player until 20 seconds have passes, a goal is scored, or possession has changed. Examples include: interfering with a free throw or holding, sinking or pulling a player not holding the ball or committing an ordinary foul during dead-time. Signaled by several consecutive whistles. Referee points at a player and then to the re-entry area.
Penalty Foul (5-meter): Called inside the 5-meter line, in which a goal was probable if a foul had not been committed. Results in a penalty shot from the 5-meter line. An example is during a fast break attempt. When a defender sinks a player that has possession of the ball immediately in front of the goal. Signaled by a long-whistle, referee holds up five fingers.
NOTE: Fouls will not be called if the offensive player is holding the ball in hand. Often, a player who is holding the ball may be pulled, pushed, dunked, etc. and no foul is called. Although spectators may become upset, there is no foul to call until the player drops the ball.

Field Diagram and Positions
Field of Play:
The diagram illustrates standard measurements for a water polo field, however, many pools were not designed for water polo and play must be adapted. For example, some pools have a shallow end. With the exception of the goalie, players may not use the bottom of the pool to stand or push off during the game. Regardless of its size, each water polo pool is marked with several important lines:
Goal lines (white)-Lines that mark the boundary on either end of the pool.
2-meter (red)-Line that not be crossed by offensive players without possession of the ball, unless the ball is inside the line and they are behind the line of the ball. Corner throws are taken from the 2-meter line, and goal throws are taken between the goal line and the 2-meter line.
5-meter (yellow)-Line from which penalty shots are taken. Also, Line outside of which an offensive player may immediately shoot the ball in one continuous motion (no pumping or faking) following an ordinary foul. The goalie becomes a regular field player if he crosses the 5-meter line.
Mid-pool (white)-Marks the spot where the referee drops the ball during the sprint. This is also
where players line up after a goal. The goalie cannot cross mid-pool.
Positions
There are two teams of seven players each. Each team has one goalie and six field players. The goalies wear red caps, the home team’s field players wear dark-colored caps, and the visiting team’s field players wear white caps.
Offense
Hole-set: An offensive player who positions himself directly in front of the opponent’s goal to run the offense. Teammates pass the ball to the hole-set, who attempts to shoot it or pass it to an open teammate. Also called the center forward, hole, hole-man, or 2-meter man.
Driver: Field players who constantly rotate around the perimeter of the offense to find scoring opportunities. A driver is not assigned to one position; rather, he rotates through the following three positions: point, positioned at the tip of the offense farthest from the opponents goal; flat, positioned about 7 meters from the goal line; and wings, positioned near the 2-meter line. Most driving occurs from the point and flat positions; the wings rotate up to the flat as teammates drive their direction.
Defense
Goalie: Defensive player who guards the goal by blocking the opponent’s shots. The goalie is the only player who can touch the ball with two hands at once. Also called goalkeeper.
Hole guard: A defensive player who guards the hole-set. The hole-guard’s main objective is to prevent the hole-set from scoring, often by purposely committing ordinary fouls. Also called center back.
