The Rules of Sevens Rugby
RUGBY sevens is a variant of rugby football in which only seven players per side feature.
Rugby union sevens is sanctioned by the International Rugby Board (IRB), and is played under substantially the same rules and on a field of the same dimensions as the 15-player game.
While a normal rugby union match lasts upwards of 80 minutes, a normal sevens game lasts seven minutes each way, with sudden death extra time when needed.
Competition finals last somewhat more than 20 minutes; each half in a competition final is 10 minutes instead of the normal 7 minutes. This allows rugby tournaments to be completed in a day or a weekend.
However, sevens scores are generally comparable to union
scores; scoring occurs with much greater regularity in sevens, owing to the fact that the defenders are more spaced out than in rugby union.
The only major rule change from rugby union regarding events on the field is that conversions must be drop goals.
