Water Polo Scoreboard: Every Clock State, Exclusion and Scorebug Explained
A water polo scoreboard must show the score, the period, a period clock counting down from 8:00, a 30-second shot clock and a live 20-second countdown for every excluded player, plus a man-up indicator whenever a team is short. Broadcasters call the same graphic a scorebug. Water polo runs three clocks at once. No other team sport asks that of an overlay.
The short answer. Players are excluded for 20 seconds rather than sent off, so the scoreboard constantly spawns and clears short timers on top of a 30-second shot clock and an 8-minute period clock, over moving blue water.
What a water polo scoreboard must show
Every element below is required in a broadcast-standard water polo scoreboard. An element you cannot source is an element you cannot render, so the third column matters as much as the first.
| Element | Why it matters | Source of data |
|---|---|---|
| Score | High scoring by team-sport standards, so it changes often and must never lag the vision. | Goal events |
| Cap colour swatch | Teams in the water are told apart by cap colour, white against dark, not by kit. A crest alone does not help. | Team setup |
| Period indicator | Four periods, not two halves. | Period start and end events |
| Period clock | Counts down from 8:00 of actual play and stops on every whistle. | Clock start, pause, resume |
| Shot clock | Tells the viewer whether an attack is alive and when a team must shoot. | Possession and reset events |
| Exclusion countdowns | Up to two live per team, each a 20-second countdown attached to a named player. | Exclusion events |
| Player-up indicator (6v5) | The most important tactical state in the sport. | Derived from active exclusions |
| Player strength | Shown only when teams are unequal, so nobody reads 7v7 all match. | Derived |
| Timeouts remaining | Scarce, and only usable in possession, so a used timeout is a real signal. | Timeout events |
The clock is the hard part: water polo runs three at once
The period clock
Under World Aquatics rules (the governing body formerly known as FINA), a match is four periods of eight minutes of actual play. The clock stops at every whistle: every foul, every exclusion, every goal, every timeout. An eight-minute period takes far longer than eight minutes in real time. A count-up clock, or one that keeps ticking through a dead ball, is simply wrong for this sport.
The common configuration error is inheriting a basketball profile and giving water polo four fifteen-minute periods. It is four times eight, and period length is a competition setting: age-group and domestic competitions often play shorter.
The shot clock
A team has 30 seconds to shoot. On a change of possession it resets to 30. In defined situations it resets to 20 instead: after a corner throw, after a rebound off the goalkeeper or the goal frame, and after an exclusion foul. So the shot clock is not one number, it is a number with a reason attached. An overlay that only understands "reset" will display 30 when the correct value is 20, and the viewer will misjudge the end of an attack.
The shot clock must also run only while the period clock runs. Two timers drifting apart is the most visible failure a water polo overlay can produce, because the venue's own clock is often in shot behind the players.
The exclusion clocks
Two exclusions can be live for the same team at once, so the overlay can be running a period clock, a shot clock and up to four separate 20-second countdowns in one frame. Each belongs to a specific player, so each needs a cap number beside it, not just a number of seconds.
Craft note. Set all three clocks in tabular figures so digits do not shuffle sideways when 9 becomes 10, and reveal tenths inside the last ten seconds. Contrast is the other constant problem: bright blue water with white splash is a moving, high-luminance background, so the scoreboard needs its own scrim.
Scoring events and what the bug does
- Goal. Increment the score first, fire the pop-up second. A viewer who glances at the bug as the ball crosses the line should never read a stale number.
- Qualifiers. A goal comes from open action, an extra-man attack, a penalty, a counter-attack or the centre forward. That distinction is the story of the possession and belongs on the sub-line.
- Penalty throw. Taken from five metres, awarded for a foul that prevents a probable goal. It chains: awarded, then scored, missed or saved. The bug needs all four states, not just the goal.
- Own goal. Credited to the opposing team, and the player stays off the scorer leaderboard.
- Extra time. Two periods of three minutes, shot clock still active.
- Shootout. The clocks come off and the bug becomes a tracker: five attempts per team as a row of dots, filled on a score, extending into sudden death after five rounds each.
Players in the water are identified by cap number, not shirt name, so every scoring pop-up should lead with it.
Exclusions, brutality and player counts
An exclusion in water polo is a 20-second removal from play, not a dismissal: the excluded player waits in the re-entry area and comes back. That is why the sport's overlay resembles ice hockey's penalty display rather than football's card display, and why a static red card graphic is the wrong model.
| Sanction | What happens | What the bug must show |
|---|---|---|
| Ordinary exclusion | Player out for 20 seconds; their team defends 6v5. | A named 20-second countdown chip plus a man-down state |
| Early return | The exclusion can end before 20 seconds elapse, most commonly when a goal is scored. | The chip clears early and the man-up state flips back immediately |
| Third exclusion, same player | That player takes no further part in the match. A substitute is permitted. | A one-off milestone card and a persistent unavailable indicator |
| Brutality | Player out for the remainder, a penalty throw to the opposition, and the team short for four minutes. | A distinct exclusion style, a four-minute countdown, and a chained penalty |
| Ejection or misconduct | Player removed; depending on the offence a substitute enters later. | Permanent removal, with the replacement timer where one applies |
So the man-up indicator cannot be a badge an operator toggles. It has to be derived from the live list of active exclusions, so it flips the instant a countdown starts and the instant one clears. Water polo is seven a side including the goalkeeper, and the strength display is only meaningful when unequal: show 6v7, not 7v7.
Extensions: the stats worth putting on the bug
A Scorebug Extension is a stat panel that pops out of the scorebug rather than taking over the screen, so the score and clocks stay visible. It can carry a sponsor banner, and it can fire on a milestone automatically or on an operator's cue. For water polo, the ones that earn their place:
- Extra-man conversion: goals from 6v5 as a share of 6v5 possessions. The most telling number in the sport, and almost nobody puts it on screen.
- Goalkeeper save percentage. Broadcasters usually want penalty saves excluded from the base figure, so make that a setting rather than a rule.
- Exclusions drawn. A centre forward whose job is to draw exclusions has a contribution that never reaches the goals column.
- Top scorer and lineup cards, built around cap numbers with the goalkeeper's cap distinguished.
How LIGR drives a water polo scoreboard
Water polo scoreboard graphics are in build at LIGR, so what follows is how the platform meets the sport's requirements rather than a shipped template.
The critical point is data. At the very top of the sport there are official feeds. Everywhere else, which is where almost all water polo streaming happens, there is none. LIGR's answer is that the scoring app is the feed: an operator on the deck presses the real events, goal, exclusion, penalty, timeout, substitution, and the graphics follow. Every press is timestamped, which is what makes stat extensions and automated highlights possible. Where an official feed exists LIGR takes it instead, and the graphics behave identically.
Everything on the bug is data-bound in Fuse, so a period length, a shot clock reset value or an exclusion duration is a variable rather than a redraw, and a competition playing shorter periods is a configuration change rather than a new template. Designs are built in Rive and rendered in HTML5, so a three-clock overlay costs no more per match than a two-clock one. Game Plans fire graphics off match events or the clock, the Control Room puts a human in the loop when you want one, and auto-mode runs with no operator at all. It is the model already running 640 or more DAZN National League matches a season in football, applied to a sport with three clocks instead of one.

Frequently asked questions
What is a water polo scoreboard overlay?
A water polo scoreboard overlay is the live score graphic rendered over a stream or a broadcast, and broadcasters call the same thing a scorebug. Water polo asks more of it than most sports: it has to carry the score, the period, an 8-minute period clock, a 30-second shot clock, a 20-second countdown for every excluded player, and a man-up indicator whenever a team is defending short.
What does a water polo scorebug need to show?
At minimum: the score, the period number, the period clock counting down from eight minutes of actual play, a 30-second shot clock, and a live countdown for every currently excluded player. It also needs a man-up indicator showing which team has the extra player, cap-colour swatches so viewers can tell the teams apart in the water, and remaining timeouts.
How long is the water polo shot clock?
Thirty seconds per possession under World Aquatics rules. It resets to 30 on a change of possession, but resets to 20 seconds in specific situations: after a corner throw, after a rebound off the goalkeeper or the goal frame, and after an exclusion foul. An overlay that always resets to 30 will show the wrong number several times a match.
What is a 20-second exclusion and how should it appear on the bug?
An exclusion removes a player from play for 20 seconds rather than sending them off. Their team defends a player short until the countdown expires or the exclusion ends early, most commonly when a goal is scored. On the bug it should be a named countdown chip carrying the player's cap number, plus a man-down state for that team that clears the moment the player returns.
How many clocks does a water polo broadcast need on screen?
Three types, and more than three timers. The period clock and shot clock are always present, and exclusion countdowns spawn on top of them, up to two per team. A busy period can have a period clock, a shot clock and four short countdowns live in one frame, the densest timing model in mainstream team sport.
Can you run water polo graphics without an official data feed?
Yes, and below the international tier you have no choice, because water polo has almost no feed coverage outside major championships. The workable model is a sport-specific scoring app operated from the pool deck: the operator presses the real events and the graphics follow. Each press is timestamped, so you also get the match log behind post-match stats and highlights.
How is a water polo scorebug different from an ice hockey one?
They share the penalty-countdown pattern, but water polo compresses it. Hockey penalties run two, four or five minutes; water polo exclusions run 20 seconds, so the man-up state flips several times a period rather than a handful of times a match. Water polo also adds a 30-second shot clock, and identifies players by cap number rather than shirt number.
