Rugby is a popular game played by men and women of every race and creed, from under age five to well over fifty, in over 100 countries of the world. After a try a conversion may be attempted by place kick or drop kick. If the ball passes over the bar and between the goal posts the conversion is successful and results in a further 2 points. Players may not be tackled without the ball. Play only stops when a try is scored, or the ball goes out of play, or an infringement occurs.
Infringements result in a penalty, or free kick, or scrum.
In a scrum the opposing forwards bind together in a unit and push against the other forwards, trying to win the ball with their feet. Substitutions are only allowed in case of injury and there is no separate offensive and defensive unit. After a try is scored, a concersion opportunity for two points can be scored in a kick through the goal posts from the spot where the player scored the try. Both team's forwards struggle to pop the ball out their end to allow the backs to play it. Players from each team interlock to fight for possession, but it is not nearly as organized as a scrum.
