Sevens is typically played only during tournaments. A sevens match
consists of two seven minute halves and is a much faster game than
fifteens due to the smaller number of players on a standard sized
pitch providing ample running space.
The players on a sevens team are as follows:
Forwards
#1 Prop
#2 Hooker
#3 Prop
Backs
#4 Scrumhalf
#5 Flyhalf
#6 Centre
#7 Wing
The same general game principles are used except tactics are quite
different. Scrums feature only opposing front rows. Rucks and mauls
are very fast and small, with defense and tackling of paramount
importance to reduce the many opportunities for breaks. One major
difference from fifteens is that after a penalty goal or try is
scored, the ball is kicked to the non-scoring team from the 50 metre
line to restart play.
Tens is played with ten players in combinations of either 5
forwards/5 backs or 3 forwards/ 7 backs. The team with the scrum
feed gets to determine the number of forwards in the scrum. The
opposing team is required to match them. The tens game is a little
slower than sevens and has a flow much more similar to fifteens.
Each of the halves is ten minutes long. Tens is also typically only
played during tournaments.
This has been a very brief overview of rugby union play. There are
many more aspects and facets to all three variations of the game.
Training is also very necessary to ensure the safety of play. Check
with your local club for practice and match times to learn more.
