A field guide to the game

Rugby Explained

Rugby is a family of running-and-passing games shaped by contest, territory, continuity and community. This guide begins with union’s 15-a-side and sevens forms, then gives the surrounding formats, laws, positions and competitions their place.

For the wider context around participation, safety, culture and change, the Ruckward starting point connects the parts of the game without reducing them to a single tradition.

Start with union.

Union is the form governed internationally by World Rugby. Its core principle is simple: advance the ball, but pass it backward; use kicking, running, set pieces and possession contests to create a route to the goal line.

Union basics

Territory, support, and a live ball.

In 15s, two teams of fifteen play for up to 80 minutes. A try is the central scoring act: grounding the ball in the opponent’s in-goal area. Play moves through carries, passes and kicks, while tackles create fresh contests for possession.

The World Rugby Laws of the Game are the governing reference for the union code, including the rules on offside, contact, set pieces and scoring.

Rugby union: the 15-a-side game

Fifteens is structured around specialist roles, contested set pieces and phases of play. Teams tend to use kicking and territorial pressure alongside carrying and passing. A match can change quickly through a penalty, turnover, kick return or well-executed lineout.

Positions are commonly grouped as forwards and backs. Forwards provide much of the scrum, lineout, carrying and close-contact work; backs organise space, kicking and wider attacking options. The standard rugby union position map is useful shorthand, but modern teams ask players to perform overlapping jobs.

1–8 Forwards

Scrum, lineout, breakdown, carrying and defensive pressure.

9–10 Half-backs

Link play, direct tempo and make tactical kicking choices.

11–15 Outside backs

Use width, defend space and contest high or territorial kicks.

Rugby sevens: the same field, fewer players

Sevens uses seven players on a full-size pitch and much shorter matches, making open-field space and repeat effort especially visible. It is a global international format and an Olympic sport; the Olympic rugby sevens overview reflects its place on the Games programme.

In both forms, the ball cannot be thrown forward. That constraint gives support lines, kicking decisions and defensive alignment their meaning. A player may kick forward, but teammates ahead of the kicker must not interfere while offside.

Rugby’s basic tension is between moving forward and keeping the ball available behind you.

Rugby league

Rugby league is a separate code with thirteen players per side, a limited tackle count and a different restart structure. It shares historical roots and some vocabulary with union, but its possession cycle and tactical rhythm are distinct. For a concise historical orientation, see the rugby league overview.

The difference matters for anyone moving between communities: a “ruck” in casual conversation may describe a different phase, expectation or law depending on the code being played.

Touch, tag and emerging variants

Touch and tag forms reduce or remove tackling, using a touch or tag to mark the end of a carry. Local rules can vary, so participants should check the organiser’s format before playing. These versions can make the game more accessible while still emphasising support, awareness and passing.

There are also adapted forms for different ages, settings and abilities. The practical question is not which form is most authentic; it is which rules, environment and expectations are in use on the day. That approach aligns with the participation perspective behind Ruckward’s practical guidance.

A plain-language check before a session: ask which code is being played, whether contact is included, how restarts work, and which local safety requirements apply. Those four answers clarify most first-time uncertainty.

For broader conversations that connect rugby with other physical disciplines, martial arts perspectives on training culture can offer a separate point of comparison without treating the sports as the same activity.

03 / Competition map

Club, provincial and international rugby overlap.

Rugby’s calendar is not one global ladder. Domestic clubs and provincial teams compete in their own structures, while international windows bring eligible players into national squads. Seasons and scheduling vary by hemisphere, competition and player agreement.

The global competitions guide gives the wider tournament context; the key is to see each event as part of a connected but not perfectly uniform calendar.

World CupThe Rugby World Cup is the major international tournament for union fifteens, played in a four-year cycle.
Six NationsAn annual northern-hemisphere international championship involving England, France, Ireland, Italy, Scotland and Wales.
Super Rugby PacificA cross-border professional competition linking teams from Australia, Fiji, New Zealand and the Pacific region.
PremiershipEngland’s leading professional club competition operates within its own domestic season and player-release context.
Olympic sevensInternational sevens has a distinct tournament circuit and reaches its Olympic peak every four years.

04 / Quick answers

The questions that unlock a match.

What is the difference between a ruck and a maul?

A ruck forms when the ball is on the ground after a tackle and players compete while staying on their feet. A maul forms when the ball carrier remains upright, is held, and teammates bind around the ball carrier.

How does sevens differ from fifteens?

Sevens has seven players per side and shorter matches on a full-size pitch. Fifteens has fifteen players, longer matches and more specialised positional demands.

Can a rugby pass go forward?

No. A hand pass must travel sideways or backward relative to the passer. Kicking forward is allowed, subject to offside and other laws.

Where can I check current safety rules?

Rules and regulations can change. Check the governing body and local organiser for the format in question; Ruckward’s safety and policy notes provide a plain-language place to begin.

A game understood in context is easier to enter.

Rugby contains competition and contact, but also volunteer work, family routines, local identity and shared responsibility. Questions about performance culture may overlap with issues explored by rugby-focused wellbeing information, while alcohol-related questions require careful, non-clinical information such as the material on alcohol and ibogaine claims. For medical conditions, consult qualified health professionals; pages discussing Parkinson’s treatment questions or ibogaine hydrochloride information should never replace clinical advice.
