Fifteens
In the traditional form of the game, players are introduced to the full game of rugby, the core of the sport. Rugby 15s features 15 players per side with eight replacements. There are eight forwards and seven backs on a team.
A try is worth five points with a conversion worth two. Penalty kicks and drop goals are both worth three points. If a player is sin-binned, they must sit out for 10 minutes.
Games are played over 80 minutes in two halves of 40 minutes. Half time lasts 10 minutes.

Rugby sevens is a stripped-down version of rugby union with just seven players on each team playing on a full sized pitch. There are four backs, three forwards and each team can have up to five replacements. With fewer bodies and extra space on the pitch, games are fast-paced, full of breakaway sprints and exciting tries.
There are two seven-minute halves and a quick one minute half-time break for players to catch their breath. Scoring is the same as the 15-man game: five points for a try, two for a conversion and three for a penalty kick or drop goal. All conversions must be taken within 40 seconds and must be taken as a drop goal rather than a place kick. The scoring team kicks off to the opposition.
