Explore by Rule
How sports are governed — the rules, and the officiating and scoring that enforce them.
What this is
Rules are what make a sport a sport: how play is governed, what is allowed, and how the officiating and scoring systems enforce and record it.
Why it matters
Rules are one of the first things a newcomer meets. Organising them alongside officiating and scoring makes the governing structure of each sport easy to navigate.
How to explore it

Rules
- OffsideA rule that prevents an attacker from gaining an advantage by being positioned too close to the opponents' goal ahead of the ball and the last defenders.
- Handball offenceA foul in football committed when an outfield player deliberately handles or controls the ball with the hand or arm.
- Direct and indirect free kicksThe two types of free kick awarded in football to restart play after a foul or other stoppage.

Officiating
- RefereeThe primary on-field official who enforces the rules, controls play, penalises fouls, awards restarts, and blows the whistle to start and stop a match.
- UmpireA match official who rules on lines, serves and dismissals in racket, bat-and-ball and net sports such as tennis, cricket and baseball — and, in racket sports, also keeps the running score.
- JudgeA judge is an official who scores performance in judged sports, awarding marks for execution and difficulty rather than counting goals or timing a race.
- Start and Stop SignalsThe whistle, gun, bell or hooter an official uses to begin and end play or a race, plus the rules that keep starts clean and penalise false starts.
