Water Polo 101

A Beginner’s Guide to Understanding the Sport

What Is Water Polo?

Water polo is a fast-paced team sport played in the water that combines swimming, passing, strategy, and teamwork. Many people describe it as a mix of soccer, basketball, and swimming — all while treading water.

Two teams compete to score goals by throwing the ball into the opposing team’s net.

The Basics

Team Size

14u & up:

7 players in the water per team at a time:
6 field players
1 goalkeeper

12u:

6 players in the water per team at a time:
5 field players
1 goalkeeper

10u:

5 players in the water per team at a time:
5 field players
1 goalkeeper

Teams also have substitutes on the bench who rotate in throughout the game.

Objective

Score more goals than the other team before time runs out.

Length of the Game

Most games are divided into:

4 quarters
Usually 6–8 minutes each (depending on age level and league)

The game clock stops often, so games are longer than the actual clock time.

The Pool

Deep Water

Most water polo is played in deep water, meaning:

Players cannot touch the bottom
Athletes tread water the entire game

This is one reason water polo athletes are known for incredible endurance.

Goals

Goals float at each end of the pool.

Players try to shoot the ball past the goalie into the net.

Important Skills

Eggbeater Kick

Eggbeater kick is the most important skill in water polo.

Instead of normal treading water, players use a circular kicking motion that allows them to:

Stay high out of the water
Pass
Shoot
Defend
Move quickly

Good eggbeater = better balance, power, and endurance.

Swimming

Players swim constantly during the game:

Sprinting
Transitioning offense to defense
Chasing loose balls
Counterattacking

Water polo swimming is unique because athletes often swim with:

Their head up
One arm dribbling the ball

Passing & Shooting

Players pass the ball around to create scoring opportunities.

Shots can be:

Power shots
Skip shots (bounce off water)
Lobs over the goalie
Quick catch-and-shoots

Positions

Goalkeeper

Protects the goal and directs the defense.

Goalies can use two hands inside the 5-meter area.

Center (Set)

The offensive player positioned in front of the opponent’s goal.

This position is very physical because defenders try to prevent them from receiving the ball.

Drivers / Perimeter Players

Players who:

Swim
Pass
Shoot
Create movement around the outside

They are similar to guards or wings in basketball.

Basic Rules

Shot Clock

Teams have a limited amount of time to shoot:

Usually 30 seconds

If they don’t shoot in time, the other team gets the ball.

Fouls

Ordinary Fouls

Minor fouls that happen frequently.

Examples:

Light contact
Impeding movement

Usually results in a free pass.

Exclusion Fouls

Major fouls.

A player must leave the pool for:

20 seconds
Or until the other team scores

This creates a “power play” situation.

No Holding Underwater

Players cannot:

Pull swimmers underwater
Hold excessively
Interfere illegally

Although water polo is physical, there are rules to keep it safe and fair.

Why It Looks So Physical

Water polo is one of the toughest sports because athletes are:

Swimming constantly
Fighting for position
Treading water nonstop
Thinking strategically

A lot happens underwater that spectators can’t easily see.

What Makes Water Polo Special?

Water polo builds:

Endurance
Strength
Teamwork
Discipline
Mental toughness
Confidence

It’s also a sport where athletes become extremely close because of how hard they work together.

Beginner Tips for Watching a Game

When watching, focus on:

Where the ball is moving
The center player near the goal
Counterattacks after turnovers
Exclusions and power plays
Communication between teammates

Once you understand transitions and fouls, the game becomes much easier to follow.
