A touchdown is the primary method of scoring in American and Canadian football, in which the ball carrier causes the football to break the plane of the end zone, or an eligible receiver catches a forward pass in the end zone, thus earning 6 points for his team (in both codes).
A touchdown is analogous to a Rugby try, with the major difference being that for a try the football has to be placed on the ground, a requirement abolished decades ago in gridiron football.
The term touchdown is also used in rugby union and rugby league to refer to the physical act of placing the ball down on the ground past the goal line.
