Rugby Union vs Rugby League

Rugby union and rugby league are two distinct codes of rugby, and the quickest way to tell them apart is team size: union fields 15 players per side, league fields 13. They also differ fundamentally in how possession works, union contests the ball after every tackle at the ruck, while league uses a structured play-the-ball and gives each team a set of six tackles to score.

The two games look similar to a newcomer, an oval ball, tackling, tries, but they play very differently once you know what to watch. Here is how the codes diverge, from players and possession to scoring and style.

A shared root, two separate games

Both codes grew from the same original sport before splitting more than a century ago over questions about professionalism and how the game should be played. From that split, the two evolved their own rules, cultures and heartlands. They are not variations of one game so much as two related sports, and a rule that is central to one is often absent from the other.

The headline differences

Before diving into detail, here is how the two codes compare on the points fans ask about most.

Element	Rugby Union	Rugby League
Players per side	15	13
After a tackle	Contest at the ruck	Play-the-ball (no true contest)
Possession rule	Ball can be won back anytime	Six tackles, then hand over
Set pieces	Scrums and lineouts (contested)	Scrums (uncontested), no lineouts
Try value	5 points	4 points
Style	Contest for possession	Continuous, territory-based

Reading down the table, almost every row points to the same theme: union is built around contesting the ball, while league is built around a structured cycle of possession. That single idea explains most of the differences between the codes.

Possession: the ruck vs the six-tackle set

This is the heart of the matter. In rugby union, when a player is tackled and goes to ground, the ball is contested at the ruck, players bind over the ball and fight to win it. Possession can change hands at any tackle, which is why the breakdown is such a crucial battleground, and why union has specialist players who hunt for turnovers.

In rugby league, the tackle does not become a genuine contest. The tackled player is allowed to get up and roll the ball back with his foot in a play-the-ball, keeping possession for his team. But there is a catch: a team gets only six tackles to make something happen. Use up all six without scoring, and possession hands over to the opposition. This “six-tackle set” gives league its distinctive rhythm, often with a kick on the last tackle to gain territory.

Set pieces: scrums and lineouts

The codes handle restarts differently too. Rugby union features contested scrums and lineouts, both genuine competitions for the ball involving specialist forwards, the lineout in particular, where players are lifted to catch a throw, has no equivalent in league. These set pieces are a big part of union’s tactical texture.

Rugby league has scrums, but they are largely uncontested formalities used to restart play, and there are no lineouts at all. Fewer set-piece contests are one reason league flows more continuously.

Players, scoring and style

The difference in numbers, 15 versus 13, mostly comes from the forwards, giving league smaller packs suited to its faster game. Scoring differs slightly too: a try is worth five points in union and four in league, with different values for kicks after that, though both reward getting the ball over the line as the main event.

The net effect is two different spectacles. Union is a stop-start contest full of technical battles for possession, prizing set-piece skill and breakdown expertise. League is faster and more continuous, a relentless cycle of tackles and play-the-balls that rewards fitness, defensive organization and clever use of the six-tackle set.

Which to watch, and where each thrives

Neither code is “better”, they simply reward different tastes. If you love tactical contests, scrums and the drama of a turnover at the breakdown, union is your game. If you prefer speed, big collisions and a constant forward push, league delivers. Union has the broader global reach and the showpiece Rugby World Cup, while league has fervent strongholds in northern England and parts of Australia.

The short version

Rugby union has 15 players and contests the ball at rucks, scrums and lineouts, making it a constant battle for possession. Rugby league has 13 players, uses a play-the-ball instead of contesting the tackle, and gives each team six tackles to score before handing over. Union is the possession-contest game; league is the faster, six-tackle, territory-based one.
