1. 6 points
   3 points
2. 2 points
   1 point

Both teams slug it out in hopes of scoring as many touchdowns as possible. Each one is worth six points, and it's topped off with a PAT or a two-point conversion attempt.

1. Construct a wedge
   Gain 10 yards
2. Find their cleats
   Shoot a basket

The offense has four downs with which to gain 10 yards. If they don’t, the other team’s offense takes over, and they'll attempt to take the ball in the opposite direction.

1. 25 minutes
   30 minutes
2. 15 minutes
   12 minutes

Each quarter is 15 minutes long. But with stoppages and commercials it often seems more like two hours. In high school football, quarters are only 12 minutes long.

1. Shoot three pointers
   Substitute players
2. Form a scrum
   Attack with spiked clubs

After each play, coaches can substitute a number of players to counter the other team’s tactics. Personnel changes can totally change the game’s momentum.

1. At the spot of the foul
   The offense gets 10 free yards.
2. Automatic 20-yard gain
   On the far hash mark

Did your cornerback just interfere with a receiver 40 yards downfield? Commence groaning ... because in the NFL, interference penalties are enforced at the spot of the foul.

1. 20 seconds
   40 seconds
2. 60 seconds
   2 minutes

The play clock is reset to 40 seconds after each play. The offense must snap the ball before that play clock runs out. If they don't, they'll be flagged by the officials.

1. They lose the game.
   Pass interference penalty
2. Targeting call
   Delay of game penalty

Offenses are expected to beat the 40-second play clock. When they don’t, they are given a five-yard delay of game penalty. Coaches often throw their clipboards in frustration at these penalties.

1. Your elbows scrape the turf.
   You surrender.
2. Your knees touch the ground.
   An opponent touches you.

In the NFL, ball carriers can go to ground and get up again. They’re not down until an opponent touches them while they’re on the ground.

1. Touchdown
   Safety
2. First down
   Field goal

It’s certainly not "safe" for the offense. When defenders tackle the ball carrier in the end zone, they receive a two-point safety ... and to add insult to injury the offense must kick the ball away.

1. At least 5 yards
   At least 10 yards
2. At least 20 yards
   Out of bounds

Kickoffs must travel at least 10 yards. And once the ball goes 10 yards, a player from either team can grab it. A very short kick is called an "onside" kick.

1. Play pauses.
   The offense must punt.
2. The defense is awarded a safety.
   Teams switch sides.

It’s called the two-minute warning, when there are just two minutes left in a half. It’s essentially a free timeout for both sides.

1. Duel
   Overtime
2. Forfeit
   Game ends in a tie

It’s not uncommon for teams to remain tied at the end of regulation. In this case, the game goes to overtime and a different set of rules kicks in.

1. A scrum ensues.
   Fans boo.
2. The other team gets a chance on offense.
   The game ends.

In overtime, if the offense kicks a field goal team also gets a turn on offense. Before 2010, a field goal immediately ended the game. But many fans saw this as an unfair ending to a close game.

1. His team loses a timeout.
   The defense is limited to 10 players.
2. His teams loses a down.
   He must exit the stadium.

Coaches often challenge the outcome of plays by throwing a red flag. But if instant replay upholds the call, the challenging coach loses a timeout.

1. The game ends.
   The other team gets a chance on offense.
2. The other team wins.
   Nothing

In overtime, if the offense scores a touchdown, the game immediately ends. But a field goal on the first possession means the other team gets a chance on offense.

1. To make the games longer
   Players like longer games.
2. Because the first team to get the ball almost always won overtime.
   To increase TV commercial revenue

A coin flip determined which team got the ball first in overtime. And in most cases, the first team would get just enough yards for a field goal and then end the game ... and the other team’s offense never even took the field.

1. Must use both hands
   Must touch at least two defenders during the play
2. Must land with both feet in bounds
   Can’t use teeth

In the NFL, a receiver must land with both feet in bounds. This is different than college football, in which the player needs only one foot in bounds for a legal catch.

1. 2-yard line
   4-yard line
2. 5-yard line
   10-yard line

After a TD, the offense can go for two points instead of kicking for one. Two-point attempts line up at the two-yard line. And even from this short distance, many two-point attempts fail.

1. The clock keeps running.
   The play clock is turned off.
2. The clock pauses momentarily.
   The game clock is set back one minute.

In college, the game clock pauses after a first down. In the NFL, though, the game clock keeps right on going, a fact that dramatically changes coaching strategies.

1. To attempt a field goal
   To score a touchdown
2. To kick off
   To punt

In a place kick, the ball is snapped to a place holder, and then the kicker boots it ... in hopes of scoring a field goal. Some kickers are accurate from more than 60 yards.

1. 5 yards
   10 yards
2. 15 yards
   Spot of the foul

It’s hard to protect quarterbacks in the NFL. Offensive linemen are slapped with 10-yard penalties for grabbing and holding charging defenders.

1. Touchdown for the defense
   Immediate turnover
2. Automatic safety
   Loss of timeouts

Chop blocks are extremely dangerous and are penalized as such. If the offense commits a chop block in their own end zone, officials declare a safety.

1. Kicking team loses
   Defense awarded two points
2. Ball is moved to spot of the kick
   Offense must kickoff

If the kicking team misses, the other team takes possession. The ball is placed at the spot of the kick attempt -- unless it's too close to the end zone. Then, the circumstances change.

1. Rushes
   Passes
2. First downs
   Scoring plays

All scoring plays are subject to booth review, where officials check instant replay. The idea is to make sure teams aren’t unfairly awarded points.

1. The offense is charged a timeout.
   The offense gets a do-over.
2. The defense gets one automatic point.
   Officials review instant replay.

Turnovers can swing the tide of a game. So since 2012, officials use instant replay to confirm each turnover before resuming play. This was one way NFL officials worked to appease outraged fans who clearly saw conflicting events on instant replay.

1. Defense awarded six points
   Defense awarded two points
2. Defense awarded three points
   Defense awarded five points

Sometimes, defenses will block an extra-point attempt and return the ball all the way to the end zone. They don’t receive a touchdown ... it’s only two points.

1. 5-yard line
   10-yard line
2. 15-yard line
   30-yard line

After a touchdown, kickers have to earn the extra point. The ball is placed at the 15-yard line. Sometimes, they miss ... a fact that quickly turn the tide of a game.

1. Referee
   Line judge
2. Back judge
   Umpire

The referee is the leader of the officiating crew. He spends much of his time observing play in the area of the quarterback.

1. A shootout
   Sudden death begins.
2. Both teams win!
   The game ends in a tie.

If both teams kick field goals in overtime, sudden death rules begin. That means the first team to score again wins the game. Just one play can make or break a team.

1. It doesn’t run.
   It’s only 10 seconds.
2. It runs just as it would for a regular play.
   It’s 70 seconds.

The game clock doesn’t run on PAT kicks. However, the play clock runs as usual, meaning a delay of game penalty can occur.

1. One
   Two
2. Three
   Four

NFL coaches have two challenge flags at their disposal. But if a challenge is unsucessful they’re docked a timeout ... meaning they must carefully weigh challenges.

1. Loss of a timeout
   Substitutions blocked
2. Loss of a down
   Loss of 15 yards

Intentional grounding (illegally throwing the ball away to avoid a sack) results in 10-yard penalty (or from the spot of the pass, whichever is more). Worse, it costs the offense a down.

1. They forfeit all timeouts.
   The game ends.
2. Officials will be waiting for them in the parking lot after the game.
   They get a third challenge attempt.

It’s a rare situation. If NFL coaches successfully use both of their challenges, they are granted still another challenge for use later in the game.

1. 5 yards
   10 yards
2. 15 yards
   20 yards

Personal fouls are serious infractions that could result in injury. That’s why the offending team is smacked with a 15-yard penalty, a fact that can swing momentum in a hurry.

1. The 50-yard line
   At the spot of the kick.
2. At the 5-yard line
   Their own 20-yard line

If an NFL team misses a kick inside the 20-yard line, the other team is granted some breathing room — they get the ball at their own 20.
