Beginner guide

Rugby, explained.

Never watched or played before? Here’s how the game works: the objective, who plays where, how points are scored, and the ruck breakdown explained simply.

The basics

Two 40-minute halves, one goal.

Score more points than the opposition by carrying, passing or kicking the ball down the pitch — then grounding it in their in-goal area.

You don’t need to know all of this to start. Come to training, play touch or contact at your own pace, and the rules will click into place as you go.

On the pitch

Forwards and backs.

A team is 15 players split into two groups: forwards, numbered 1–8, and backs, numbered 9–15. Your shirt number tells you (roughly) what your job is.

Numbers 1–8

Forwards

  • Props (1, 3)
  • Hooker (2)
  • Locks (4, 5)
  • Flankers (6, 7)
  • Number 8

They win possession at scrums and lineouts, protect the ball at rucks, and do most of the heavy tackling.

Numbers 9–15

Backs

  • Scrum-half (9)
  • Fly-half (10)
  • Wings (11, 14)
  • Inside & outside centres (12, 13)
  • Fullback (15)

They use speed and space to run, pass and kick — turning possession the forwards win into points.

Points on the board

How you score.

Four ways to put points on the board, worth different amounts.

5 points

Try

Pressing the ball firmly onto the ground in the opponent’s in-goal area.

2 points

Conversion

A kick at goal taken right after a try, in line with where the ball was grounded.

3 points

Penalty goal

A kick through the posts, awarded after a major opposition penalty.

3 points

Drop goal

A kick through the posts during open play — the ball must touch the ground first.

Core rules

Three to remember early.

Everything else builds on these.

The breakdown

Rucks and the gate.

A ruck forms when the ball carrier is tackled and one or more players from each team bind over the ball on their feet to contest it. The “gate” is the entry channel directly behind your team’s hindmost foot — the only way in.

Rule 1

Hands off

Once a ruck has formed, no one may pick up or handle the ball. Use your feet to push opponents back or hook the ball backwards.

Rule 2

Enter through the gate

Join a ruck only from directly behind your own team’s hindmost foot. Coming in from the side is an immediate penalty.

Rule 3

Stay on your feet

Support your own body weight at all times. Diving on the ball or going to ground on purpose is a penalty.

Rule 4

Offside line

An imaginary line runs sideline to sideline through the hindmost foot of the last player in the ruck. Uninvolved players stay behind it until the ball comes out.

What to avoid: a wide gate from a lateral (across-pitch) tackle placement lets multiple defenders drive in over the ball.

The dashed lines are the offside lines — one for each team, running through the hindmost foot at the ruck. This is Rule 4 above, shown on the pitch.

Why a narrow gate helps the attacking team: going to ground parallel to the sideline (rather than across it) presents a narrow target. That limits how many defenders can legally challenge for the ball and lets a single supporting player protect it — freeing up the rest of the team for the next phase.
