Ruck
A contest for the ball on the ground, formed when players from both teams bind over it after a tackle.
What it says
A ruck forms when at least one player from each team is on their feet, in contact, and over the ball on the ground. Players can only join by binding onto a teammate or opponent already there, and once in the ruck, they can't use their hands on the ball.
Why it exists
After a tackle, the ball needs a fair way to be contested and recycled rather than players just diving on it and holding it up indefinitely. The ruck lets both teams compete for it through pushing and clearing out, not grabbing, which keeps the game flowing and physical rather than turning every tackle into a wrestling match.
In practice
Once a ruck has formed, hands off the ball, only feet can be used to move it. Players arriving late have to join from behind their own team's hindmost foot, not sideways or from the side, and can't dive over the top. Most penalties here come from hands in the ruck, sealing off the ball, or entering from the wrong side.
Common confusions
Not every pile-up after a tackle is a ruck. It isn't one until it meets the actual definition: players bound and on their feet over the ball. Before that point, a player on the ground can still be tackled or the ball can be played by hand, which is why a quick pick-and-go can happen before a ruck has properly formed.
