Rugby Union Explained: A Beginner's Guide to the Rules and Scoring

Rugby union can look like controlled chaos to a newcomer, but underneath the collisions is a game with clear structure and logic. If you learn a handful of core ideas, the sport quickly becomes one of the most rewarding to watch.

A rugby union match is played by two teams of 15 players each over 80 minutes, split into two 40-minute halves. The objective is to score more points than the opposition by carrying, passing, and kicking an oval ball into the opponent's territory and ultimately over their goal line.

The single most important rule for beginners to understand is that the ball cannot be passed forward. Every pass must travel sideways or backward. Teams therefore make ground by running the ball forward while passing it laterally, or by kicking it downfield. This backward-passing rule is what gives rugby its distinctive diagonal, interlocking style of attack.

There are four ways to score. A try, worth 5 points, is the main prize and is scored by grounding the ball over the opponent's goal line. After a try, the scoring team gets a conversion, a kick at the goalposts worth 2 more points, taken in line with where the try was scored (which is why teams try to score closer to the middle). A penalty kick, awarded after the other team commits an offense, is worth 3 points if kicked through the posts. Finally, a drop goal, worth 3 points, is scored when a player drop-kicks the ball over the crossbar during open play.

When play stops, the game restarts with one of two set pieces. A scrum is used to restart play after a minor infringement, such as a forward pass. Eight players from each team bind together and push against each other to contest possession of the ball, which is fed into the middle. A lineout restarts play after the ball goes out of bounds. Players line up perpendicular to the touchline, and one team throws the ball in straight down the middle, often lifting a teammate high to catch it.

During open play, when a ball carrier is tackled to the ground, a ruck usually forms as players from both sides bind over the ball and try to secure it for their team. If the ball carrier stays on their feet and teammates and opponents bind on, it is called a maul. Learning to spot rucks and mauls is key to following where possession is going.

The tackle itself is governed by strict safety rules. Tackles must be made below the shoulders, and dangerous high tackles are penalized heavily, often with a yellow card (ten minutes in the "sin bin") or a red card (permanent removal). Player welfare, especially around head contact, has become central to how the modern game is refereed.

Positions fall into two groups. The eight forwards (numbers 1 to 8) are generally the larger players who contest scrums, lineouts, and rucks and do much of the close-quarters work. The seven backs (numbers 9 to 15) are typically faster and handle much of the running, passing, and kicking that turns possession into points. The scrum-half (9) and fly-half (10) are the key decision-makers who link the forwards and backs.

At the top level, the sport's showcase is the Rugby World Cup, held every four years, alongside major annual competitions such as the Six Nations in the northern hemisphere and the Rugby Championship in the south. Rugby union is also distinct from rugby league, a related but separate 13-a-side code with different rules.

Once you understand backward passing, the four ways to score, and the basic set pieces, the game opens up. What first looks like a pile-up becomes a contest for possession, and every kick, pass, and tackle starts to carry clear meaning.
