Scoring

Methods of scoring include:

Touchdown

Achieved when the ball is in possession of a player in the opponent's goal area, or when the ball in the possession of a player crosses or touches the plane of the opponent's goal-line. Worth 6 points.

Conversion

A scrimmage play from any point between the hash marks on or outside the opponent's five yard line. Attempted after scoring a touchdown, either by kicking an extra point (worth one point), or by scoring with a carrying or passing play (worth two points). This is known as a convert or two-point Conversion.

Field Goal

Scored by a drop kick or place kick (except on a kick-off) when the ball, after being kicked and without again touching the ground, goes over the cross bar and between the goal posts (or goal posts produced) of the opponent's goal. Worth three points.

Safety

Scored when the ball becomes dead in the possession of a team in its own goal area, or touches/crosses the dead-line or side-line-in-goal as a result of the ball having been carried, kicked, fumbled or otherwise directed from the field of play into the goal area by the team scored against, or as a direct result of a kick from scrimmage having been blocked in the field of play or goal area. Worth two points.

Rouge

Scored when the ball becomes dead in possession of a team in its own goal area or when the ball touches or crosses the deadline, or side-line-in-goal, and touches the ground, a player, or some object beyond these lines. Worth one point. Also awarded from a missed field goal causing the ball to go out of play, or conceded by the defence.

Although rouge (French: red) is the proper term, in popular use it is often called a single. In early Canadian football rules a single point was deducted from a team failing to advance the ball from the end zone. If a team had no points, this put them "in the red," with a negative score.
