American football, known as Gridiron football or simply football in North America, is a sport that originated in the United States of America. The game is played on a 100 yard field with two endzones that are 10 yards deep. The goal of the game is to score the most points in the alloted time, primarily by advancing the ball into the opponent's endzone.

The National Football League is the premier football league in the world, with all its teams located in the United States.

Methods of Scoring

Touchdown

A touchdown is worth 6 points. A touchdown is scored when a player has possession of the ball and the ball crosses the goal line of the opposing team's endzone. Touchdowns can be scored on offense, defense, and special teams.

Point After Touchdown

A point after touchdown (PAT), or extra point, is worth 1 point. A team can elect to attempt a PAT after they score a touchdown. A PAT is scored when the football is kicked between the goalposts, which stand directly behind the endzone. The line of scrimmage is placed at the 2 yard line for a PAT, and the ball is kicked from the 9 yard line.

2-Point Conversion

A 2-point conversion is an alternative to the PAT that is worth 2 points. After a touchdown, the scoring team can execute 1 offensive play attempting to cross into the endzone. The line of scrimmage is the 2 yard line.

Field Goal

A field goal is worth 3 points, and is scored when the offensive team kicks the ball between the goalposts. This can be attempted anywhere on the field.

Safety

A safety occurs when a defensive player tackles an offensive player in their own endzone and are worth 2 points. The team scoring the safety is also awarded the ball on the following kickoff.
