The rules of football are very different from those of American football. Although American football originated from rugby, the two sports are completely different. Football usually refers to football. American football actually originated from rugby and gradually evolved into different rules, equipment and the following differences.

American football and rugby use different ball shapes. American football is smaller and longer, with both long ends pointed, which increases the incomprehensibility of the ball after landing and makes the game more interesting. Rugby players don't need to wear helmets and pads.

After the touchdown, the scoring team can also kick and shoot once on the imaginary line perpendicular to the goal line, and get 2 points, and get a penalty shot because one side fouls, and get 3 points.
