What it is Filled
A drop goal is a goal scored during open play in rugby union or rugby league by dropping the ball onto the ground and kicking it as it rises from the bounce so that it passes over the opponents' crossbar between the goalposts.
In scope
- The relationship between a drop-goal attempt and an awarded drop goal
- Drop-kick execution and observable ball trajectory
- Sporting code, competition and rule edition governing eligibility
- Immediate match circumstances affecting the attempt
- Awarded points and the resulting match-state transition
Out of scope
- The general concept of a goal across sports
- Drop kicks used for restarts or purposes other than attempting a goal
- Penalty-goal and conversion procedures as independent scoring actions
- Complete match, team and player models
- Goalpost construction and playing-field engineering
Why it exists Filled
Enable an agent to recognise a drop-goal attempt, evaluate its outcome under the applicable sporting rules, and distinguish an awarded drop goal from other goals and kicks.
Distinguishing features Filled
- The registry label denotes a rugby scoring action rather than an instruction to abandon an objective.
- The kick involves dropping the ball to the ground and kicking it on its rebound, distinguishing its execution from a punt or a place kick.
- A drop kick alone is insufficient: evidence must establish a goal attempt in a context eligible for a drop goal under the governing rules.
- An awarded drop goal requires the applicable scoring conditions and adjudication; an attempted or apparently successful kick is recorded separately.
- The narrower model adds execution and eligibility tests to the broader goal concept without treating every scoring kick as a drop goal.
What robots and AI may and may not do Filled
Must not
- Misreport the points value by confusing the rules of rugby union and rugby league.
- Report unconfirmed scores as official.
- Assist spot-fixing or betting fraud on scoring events.
Only with a human decision
- Publishing allegations of match-fixing tied to scoring events.
May
- Explain the drop goal, how it is scored in rugby union and league, and its tactical use.
- Report drop goals in match records from official sources.
Moral aspects Filled
- Accurate scoring records matter to players, teams and fair competition.
Who is affected
- Players
- Teams
- Supporters
Owners Filled
Steward
Nobody owns the play; the governing bodies of each rugby code set its rules.

Identity and identifiers required Filled
- Vercy registry: vr.tr.drop-goal
- Wikidata: Q2298409 (https://www.wikidata.org/wiki/Q2298409)
Direct properties not applicable Not applicable
- Governing rules: Sporting code, competition, rule edition and effective date
- Drop-kick execution: Confirmed rebound contact; contrary evidence; inconclusive
- Attempt context: Open play; penalty sequence; conversion sequence; restart sequence; other; uncertain
- Kick location: Field coordinates in metres, with field orientation and uncertainty

Plane ACT: no invented physical properties.
Recognition optional Filled
- The kicker releases the ball onto the ground and strikes it after it bounces, unlike a punt struck before ground contact.
- The attempt occurs during open play rather than as a conversion or a penalty kick at goal.
- A successful attempt sends the ball above the crossbar and between the opponents' goalposts, with the award confirmed by an official.
Capabilities and actions required Filled
- Classify a recorded kick as a candidate drop-goal attempt and identify missing evidence.
- Evaluate execution and contextual eligibility against a cited governing rule.
- Separate an observed trajectory from an official scoring decision.
- Calculate an awarded score change once rules and adjudication are established.
- Identify the permitted continuation or restart following the outcome.
- Compare a prospective drop-goal attempt with other immediate play options using explicit uncertainty.
Hazards and failure modes required Filled
- Contesting or attempting the kick can expose players to collisions and falls.
- An unsuccessful attempt can surrender possession or leave the kicking team poorly positioned to defend.
- Misidentifying the kick type or applying the wrong competition rules can produce an incorrect scoring decision.
Standards and interfaces required Filled
- The Laws of the Game issued by World Rugby govern the definition, validity and scoring of drop goals in rugby union.
- The International Laws of the Game issued by International Rugby League govern drop goals in rugby league, subject to applicable competition variations.
Context of use required Filled
- A drop goal is attempted during open play in rugby union or rugby league to score through the opponents' goal.
- It is used when a player judges that the field position, available space and match situation favor a scoring kick.
- Officials and analysts distinguish it from tries, conversions and penalty goals when recording the score.

Open questions
- Does the registry provenance confirm the rugby meaning, and does the entry cover both rugby union and rugby league?
- Does an existing world model already own drop goal or the relevant goal specialisation, requiring a link instead of a separate publication?
- Which official rule editions and competition variations must be researched for scoring values, location conditions and contextual restrictions?
- How should code-specific terms such as field goal map to this entry without merging distinct historical or sporting meanings?
- What minimum evidence is sufficient to classify an attempt when intent, rebound contact or the official decision is unavailable?
