A field goal is worth 3 points. Drop-kicked field goals are worth 6 points. To score a field goal, two defensive players create the shape of an "H" and then each post steps two paces away from each other. These players are the goalposts.

On any field goal attempt the ball must be hiked from center at the line of scrimmage and must be kicked from the ground, either via a holder or via a drop-kick.

No rushing is allowed against a field goal attempt and no fake field goals are allowed. The play is off the clock. The ball cannot be advanced by either team, even if blocked or short. The ball can be held (or dropped-kicked) from anywhere behind the line the scrimmage.

Time keeping notes: The clock automatically stops for a field goal attempt, however there will be an automatic ten second run-off after the attempt. 

On drop-kick attempts, the defense may attempt to block the kick but only from their side of the line of scrimmage.

7 points are awarded to a team that scores a touchdown. The scoring team can elect to decline the automatic 1 point conversion and attempt a two-point conversion from three paces out. If they are successful in the conversion they are awarded 2 points, making the touchdown and conversion worth 8 points. If they are not successful, they walk away with 6 points instead.

A two-point conversion can be run back by the defense for two points.

A touchdown is scored when an offensive player has control of the ball and has one foot (or the majority of his or her body while in a prone position) in the end zone. As with all all catches, some leeway on whether the player's foot was in bounds is given if the player has completed a "spectacular" catch.

There are no limits or regulations regarding punting formations.

Punts that cross the line of scrimmage cannot be advanced by the kicking team

Any punt that does not cross the line of scrimmage can be advanced by the kicking team.

There are no limitations regarding the number of players in motion.

The ball must be snapped from the ground, (not from a standing position.) Any "double clutching" is considered an illegal snap.

Illegal procedure

Offenses are allowed 30 seconds from the time the ball is spotted back at the LOS. The defense is responsible for spotting the ball and then keeping track of the time -- counting out loud as the time gets to ten seconds ("ten, nine, eight, seven... etc."). Once the offense breaks the huddle the play clock is stopped. If the offense stays in the huddle after the 30 seconds, a "delay of game" penalty will be enforced and the ball will be moved back 4 paces.

Offenses can't re-huddle.

Only 5 offensive players besides the quarterback may be eligible to catch a forward pass beyond the line of scrimmage. If teams have seven a side, the center is automatically ineligible. If more than seven a side, the center and one lineman (lineperson, sorry) is ineligible (etc.)

INELIGIBLE PLAYERS MUST LINE UP ON THE LINE OF SCRIMMAGE ADJACENT TO EACH OTHER AND ON THE LINE OF SCRIMMAGE.

Even with six players or less on a team, a team with one extra player must have an ineligible center who cannot catch a forward pass.

Illegal procedure

Running plays are legal. Note: when the offense blocks downfield or when the quarterback (the player who receives the snap) gives the ball to a teammate (via a handoff, lateral, or forward pass), the defense can rush past the line of scrimmage to tag the ball carrier without waiting to count to "4 Mississippi".

Any number of forward passes are allowed from behind the line of scrimmage. (Exception: a player cannot pass to himself/herself.) Once past the line of scrimmage, only backward passes are allowed. (Backward passes are allowed from any player to any player at any time, including "ineligible" linemen.)

An incomplete forward pass behind the line of scrimmage is considered a dead ball, an incomplete backwards pass, including a muffed snap, is a live ball.

Intentional Grounding

At the start of the game and of the second half, and after every score, there will be a kickoff.

Kickoffs can either be punted or kicked from the ground (using a holder or a "heel-hole" in the ground.)

A "neutral zone" of fifteen yards from the spot of the kick is established before the kick. Players cannot enter this zone before the kick.
