| The Rules of Water Polo - EXPLAINED |
Water polo is an intense, fast-paced sport that combines swimming, strategy, teamwork, and skill. Although its basic premise is simple — score more goals than the other team — the game has a unique set of rules and structures that make it both challenging and thrilling to play and watch. Whether you’re a beginner looking to understand the sport or a fan wanting to deepen your knowledge, this guide will walk you through the fundamental rules of water polo.
The Objective of the Game
At its heart, water polo is about outscoring your opponent by throwing a floating ball into the opposing team’s goal. Each successful goal counts for one point, and the team with the most goals at the end of the match is declared the winner.
Team Structure and Basic Setup

Water polo is played by two teams, each consisting of 14 players. However, only seven players from each team are in the pool at any given time: one goalkeeper and six field players. The goalkeeper’s primary job is to guard the goal, while the field players work together to pass, defend, and score.
The playing area — the pool — can be up to 30 meters long and 20 meters wide, with a minimum depth of 1.8 meters. The goals themselves are 3 meters wide and sit 0.9 meters above the water’s surface.
Key Markings in the Pool
To help organize play, the pool has specific lines:
-
Midline: Divides the pool in half and is where the game starts.
-
2-Metre Line (Red): Located two meters in front of each goal, this area restricts offensive players from receiving passes.
-
5-Metre Line (Yellow): Positioned five meters from each goal, this line is significant for fouls, penalty shots, and goalkeeper privileges.
How Play Starts and Progresses
A game of water polo begins with a sprint. The ball is placed at the pool’s midline, and when the referee blows the whistle, players from both teams race to claim possession.
Once a team controls the ball, they can pass it between teammates in any direction or swim with it by pushing it ahead. Unlike other ball sports, field players must handle the ball with only one hand at a time — only the goalkeeper can use both hands within the five-meter area.
Teams must move quickly: they have a maximum of 30 seconds to attempt a shot once they gain possession. If they fail to shoot within this time, they lose possession, and the opposing team is awarded the ball.
Defensive Play
Defending teams can intercept passes, block shots, or push attackers away from the goal to regain possession. Much of the physical contest in water polo happens as players wrestle for position, making strength and stamina crucial parts of the game.
Game Duration
A standard water polo match is divided into four periods, each lasting eight minutes. The clock stops for major fouls and timeouts but runs during ordinary fouls and general play. The team with the highest score at the end of the four periods wins.
Understanding Fouls
Fouls are common in water polo and come in two categories: ordinary fouls and major fouls.
Ordinary Fouls:
These are minor infractions, such as impeding an opponent who doesn’t have the ball. The penalty is straightforward: possession of the ball is awarded to the opposing team. The game clock continues to run, and the fouled team must restart play within three seconds.
Major Fouls:
Also known as exclusions or kickouts, major fouls are more serious and include actions like holding, sinking, or pulling back an opponent. When a major foul occurs, the offending player must leave the pool for 20 seconds, leaving their team short-handed. If a player accumulates three major fouls, they are ejected from the game entirely. In cases of violent play or deliberate attempts to injure — called brutality fouls — the player is immediately removed from the game.
Special Areas and Penalties
2-Metre Line Rules:
Offensive players are not allowed to receive a pass inside the two-meter area unless the ball or player entered that zone after the pass was made. However, players can still swim through this area while in possession of the ball.
5-Metre Line Rules:
The five-meter line is crucial for penalties and certain fouls. If a foul occurs inside this area and prevents a likely goal, the fouled player is awarded a penalty shot. For this, the player takes a direct shot at goal from the five-meter line, with only the goalkeeper allowed to defend.
The five-meter line also marks the limit of the goalkeeper’s special privilege — they can use both hands to handle the ball, but only within this zone.
Timeouts and Substitutions
Each team is allowed one one-minute timeout per period. Coaches often use these breaks to rest players or adjust strategies.
Teams also have up to seven substitutes on the bench, including a backup goalkeeper. Substitutions are made during stoppages or through designated areas at the pool’s edge.
Water polo is a game that demands high levels of endurance, teamwork, and tactical thinking. Its rules are relatively straightforward but add layers of excitement and complexity to the sport. From lightning-fast sprints to hard-fought goals and dramatic penalty shots, each match is a spectacle of skill and determination.
Whether you’re gearing up to play, watch, or simply understand water polo better, knowing these fundamentals will help you appreciate the sport’s fast-paced action and strategic depth.
