15 a side Rugby is the cornerstone of the game of rugby union. It is a full contact sport involving tackles, rucks, mauls, lineouts and scrums.

Each team of 15 players is divided into eight forwards and seven backs, each with defined roles in the team. The forwards are ball-winners who also play a major part in retaining possession when a player on their side is tackled. They take part in rugby's set pieces – the scrum and the lineout – and secure possession; the backs receive the ball from the forwards then run and pass to create space.

The object of the game is to score more points than the opposition. Points are accumulated through scoring a try (five points), a penalty (three points), a drop goal (three points) and a conversion (two points).
