How the Game Is Played

The goal is simple: score more goals than the other team. A goal counts when the entire ball crosses the goal line between the posts and beneath the crossbar.

1

The Sprint

Each quarter begins with the teams at opposite ends of the pool. At the whistle, players sprint to the center for the ball.

2

Set the Offense

The offense spreads out, passes around the perimeter, and tries to create an open shot before the 30-second shot clock expires.

3

The Center Battle

One attacker often sets up directly in front of the goal at center, also called set or two-meter. The center may shoot, pass, or draw an exclusion.

4

Take the Shot

Shots may come from the perimeter, center, a drive toward the goal, a counterattack, or during a 6-on-5 advantage.

5

Change Possession

After a save, turnover, goal, or shot-clock violation, play quickly reverses direction and the other team counterattacks.

6

The 6-on-5

When a defender is excluded, the offense temporarily has an extra field player and moves the ball quickly to create an open shot.

Possession → Set the offense → Create a shot → Change possession → Counterattack

Water Polo Rules Made Simple

Water polo moves fast, includes frequent whistles, and allows much more physical contact than many other sports. These are the rules parents will notice most often.

Water Polo Is a Contact Sport

Defenders may challenge and make significant contact with a player who is holding the ball. Holding, sinking, or pulling back a player who does not have the ball can result in a foul. Dangerous or violent play is never permitted.

Ordinary Foul

The most common foul. The other team receives a free throw, and play usually continues immediately.

Exclusion or “Kickout”

The player temporarily leaves the field, creating a 6-on-5. It lasts up to 20 seconds and may end sooner after a goal or change of possession.

Penalty Foul

A serious foul that prevents a probable goal may result in a 5-meter penalty shot against the goalkeeper.

Why Didn’t the Referee Call That?

Water polo uses the advantage rule. A referee may allow play to continue when stopping it would take away the offensive team’s advantage. No whistle does not necessarily mean the referee missed the contact.

Why Does the 6-Meter Line Matter?

After certain free throws, a player with the ball outside 6 meters may shoot directly at the goal. That is why you may see a whistle followed immediately by a long shot.

Ohio High School Water Polo

Ohio high school water polo follows NFHS rules along with policies established for Ohio competition. Tournament hosts may announce limited adjustments, such as modified period lengths or running-clock procedures, so an occasional tournament may look slightly different from a standard game.
