Rugby Union vs Rugby League: What’s the Difference?
Rugby union and rugby league are two distinct sports that share the same origins but have developed very different rules, structures, and cultures. The most immediate differences are the number of players (15 per side in union, 13 in league) and what happens after a tackle: union continues to contest possession through rucks and mauls, while league gives the attacking team six tackles before handing the ball over. These two rules alone shape everything else about how each game is played.
Players on the Field
A rugby union team fields 15 players, with eight forwards and seven backs. The extra two players compared to league are an additional prop and an additional back-row forward, which means union scrums and lineouts are larger and more physically demanding set-pieces.
Rugby league runs with 13 players per side. The positions that disappear compared to union are the two flankers, which is directly connected to how the breakdown works in each game. With no flankers hunting at the tackle, the game opens up in different ways.
| Feature | Rugby Union | Rugby League |
|---|---|---|
| Players per side | 15 | 13 |
| Forwards | 8 | 6 |
| Backs | 7 | 7 |
Scoring: How the Points Differ
Scoring is one of the clearer areas where the two codes diverge. The values assigned to tries, conversions, drop goals, and penalties are all different.
| Scoring Action | Rugby Union | Rugby League |
|---|---|---|
| Try | 5 points | 4 points |
| Conversion | 2 points | 2 points |
| Penalty goal | 3 points | 2 points |
| Drop goal | 3 points | 1 point |
The drop goal difference is particularly significant in union, where a single drop goal can swing a tight match by three points. In league, the drop goal is largely a last-resort weapon worth just one point, used mainly to win close games in the dying moments.
Tackling and What Happens Next
This is the biggest structural difference between the two games, and it fundamentally changes the flow of play.
Rugby Union: The Breakdown
In union, when a player is tackled, possession is genuinely contested. The tackled player must release the ball, and a ruck or maul forms as players from both teams compete for it. A ruck happens when the ball is on the ground and players are bound over it. A maul forms when the ball carrier is held but still on their feet and teammates bind around them.
Flankers exist specifically to be first to these breakdown situations. Winning breakdown ball, slowing it down, or stealing possession entirely is a core tactical element of union. Teams employ specialist “jackal” players who can legally compete for the ball on the ground if they stay on their feet.
Rugby League: The Six-Tackle Rule
League works completely differently. After a tackle, the tackled player gets up and plays the ball back with their foot (the “play-the-ball”). There is no contest for possession. The attacking team retains the ball and continues their set.
Each team gets six tackles before they must hand the ball to the opposition. After the fifth tackle, teams almost always kick the ball long to pin the opposition back, resetting the territorial position. This creates a rhythmic, structured pattern of play that is very different from the more chaotic and contested nature of union.
Scrums and Lineouts
Scrums
In union, scrums are fully contested. Eight forwards from each side bind together and push against each other, with the hooker competing to win the ball. A dominant scrum can win penalties and is considered a genuine weapon. Scrums collapse, reset, and take time. They are technical and physically demanding.
In league, scrums are uncontested. They exist as a way to restart play after certain infringements, but neither side is genuinely trying to push the other off the ball. The team putting the ball in almost always retains it. Scrums in league take seconds and are largely a formality.
Lineouts
Lineouts exist only in rugby union. When the ball goes into touch, play is restarted with a lineout: players from both teams line up, and the hooker throws the ball in. Forwards are lifted by teammates to compete for the ball in the air. Lineout formations are complex, with coded calls, and defending teams try to steal the ball at the top of the jump.
Rugby league has no lineouts at all. When the ball goes into touch, play simply restarts with a handover or a tap kick, depending on the situation. This removes another major area of contest and keeps the game moving faster.
Offside Rules
Both sports have offside rules, but they work differently in open play and at set pieces.
In union, the offside line in open play is generally the position of the last foot of the hindmost player in a ruck or maul. Players must retreat behind that line and cannot interfere with play until the ball has left. At lineouts, players must stay ten metres back unless competing for the ball.
In league, the offside rule is simpler. Defenders must retreat ten metres from the play-the-ball after each tackle. If they fail to do so in time, they are offside. This is one of the most frequently penalised offences in league and shapes how quickly defenders can reorganise between tackles.
Which Competitions Use Which Code?
Rugby Union
- Six Nations Championship (England, Ireland, Scotland, Wales, France, Italy)
- Rugby World Cup (governed by World Rugby)
- Premiership Rugby (England’s top club competition)
- United Rugby Championship (Pro-franchise competition across UK, Ireland, Italy, South Africa)
- The Rugby Championship (Argentina, Australia, New Zealand, South Africa)
- Champions Cup (European club competition)
Rugby League
- Super League (UK-based professional competition)
- NRL (National Rugby League, Australia and New Zealand)
- State of Origin (Queensland vs New South Wales, the most watched annual rugby league event)
- Rugby League World Cup (separate from the union World Cup)
Global Popularity: Which Code Is Bigger?
Rugby union is the more widely played and watched code globally. It is the dominant form of rugby in England, Ireland, Scotland, Wales, France, South Africa, Argentina, Japan, and the Pacific Islands. The Rugby World Cup is one of the highest-attended sporting events in the world.
Rugby league is strongest in specific regions: northern England (particularly Yorkshire and Lancashire), Australia, New Zealand, Papua New Guinea, and parts of France. The NRL in Australia draws enormous audiences domestically, and State of Origin regularly attracts over 80,000 fans to stadium matches. But outside these strongholds, league has limited footprint.
By most measures, union has a larger international following. League, however, has an intensely loyal fanbase in its heartland regions and is often described as a faster, more accessible spectator sport.
Which Should a Beginner Watch?
If you are new to rugby and want to understand what is happening on screen as quickly as possible, league is the easier starting point. The six-tackle structure is simple to follow, the game flows without lengthy stoppages, and the action is continuous. You will understand the basics of what is happening within a couple of phases of play.
Union takes more time to learn. The breakdown, lineout calls, scrum laws, and offside nuances are complex, and even experienced viewers sometimes disagree about what the referee has penalised and why. That said, union rewards deeper knowledge. Once you understand what is happening at the breakdown or why a lineout formation has been called, the tactical layers become genuinely absorbing.
The honest answer is to watch both. A Six Nations match and an NRL game in the same weekend will give you a clear sense of what distinguishes them. They are different sports that happen to use the same shaped ball.
