A game played in London, Paris or Tokyo can look just like one in the United States, but “international rules” do not mean every American football competition uses one identical rulebook. The key distinction is who runs the game: IFAF competitions generally use rules built on the U.S. college game, while an NFL game overseas follows NFL rules. Once you know that, the basics are familiar—and a few differences become easier to spot.
Which rulebook applies?
The International Federation of American Football (IFAF) governs the sport internationally and publishes rules for its competitions, including international tournaments. Its rulebook is closely based on NCAA football, with adaptations for the international game. National leagues and tournament organizers can also set competition-specific details, particularly for youth or shorter-format events.
An NFL regular-season game played outside the United States is still an NFL game under NFL rules. The venue does not change the rulebook. Likewise, a college game played abroad follows the rules of its governing competition. If you are watching a particular league, its own regulations are the best guide to details such as overtime and timing.
The basic game is the same
In standard 11-a-side football, each team has 11 players on the field. The offense tries to advance the ball toward the opponent’s end zone, while the defense tries to stop it or win possession.
The offense gets four downs to gain 10 yards. If it succeeds, it earns a new set of four downs. If it falls short, the other team usually takes over at the spot of the ball, though teams often punt on fourth down to give the opponent a longer field to cover. A quarterback may throw one forward pass on a play, and it must be released from behind the line of scrimmage. Backward or sideways passes are allowed, but a loose ball can be recovered by either team.
The field is 100 yards between the goal lines, with a 10-yard end zone at each end. Yard lines, sidelines and hash marks help officials place the ball and judge whether a team has gained enough ground. The IFAF/NCAA-style hash marks are closer to the sidelines than the NFL’s, which can affect where the next play begins and the angle of a kick.
Scoring and possession
| Play | Points | What it means |
|---|---|---|
| Touchdown | 6 | A player carries the ball into the end zone or catches it there. |
| Extra-point kick | 1 | After a touchdown, the team kicks through the uprights. |
| Two-point try | 2 | The team runs or passes the ball into the end zone after a touchdown. |
| Field goal | 3 | A kick goes through the uprights during a normal down. |
| Safety | 2 | The defense tackles an opponent with the ball in that team’s own end zone, or forces certain other outcomes there. |
After a touchdown, the scoring team chooses between a kick for one point and a play from scrimmage for two. That choice can matter late in a close game: a team trailing by eight may need a touchdown and a successful two-point try just to tie.
Kickoffs, punts and turnovers are the other major ways possession changes. A punt is usually a fourth-down decision when the offense wants to trade the ball for better field position. An interception or recovered fumble can flip the game immediately.
Where IFAF-style rules can differ from the NFL
Because IFAF rules are based on the college game, a few familiar details may differ from what NFL viewers expect. The differences are not always obvious on a first watch, but they can influence close calls and game strategy.
- Catches near the sideline: Under NCAA-style rules, a receiver generally needs control of the ball and one foot down in bounds. NFL rules generally require two feet. A pass caught on an international IFAF field is judged under that competition’s rulebook, not automatically by NFL standards.
- Hash marks: IFAF/NCAA-style hash marks are farther apart than NFL hash marks. The ball can therefore be spotted farther from the center of the field, changing the available angles for plays and field-goal attempts.
- Clock and game management: Clock procedures, stoppages and the way the clock restarts can vary by rulebook. Coaches and players must know the competition’s timing rules rather than assume the NFL’s procedures apply.
- Overtime: IFAF competitions generally use a college-style approach, giving both teams opportunities to score from a set field position. The exact procedure can depend on the current rules and tournament regulations; NFL overtime is a separate system.
Penalty principles are broadly recognizable. Officials may flag holding, illegal contact, offside, pass interference and personal fouls, with enforcement based on the type and location of the foul. A five-, 10- or 15-yard penalty is common, although some fouls are enforced from the spot or carry additional consequences. The referee’s announcement tells you the foul and its effect on the down.
How to tell what you are watching
Check the competition before comparing a decision with one you saw in the NFL. An IFAF tournament, a national league and an NFL international fixture can all be played outside the United States, yet use different rulebooks. The league’s regulations or broadcast information should identify the governing rules.
For a new viewer, the most useful things to track are the down-and-distance display, the line of scrimmage and the clock. If the offense faces third-and-7, it needs seven yards for a first down; it does not have to score on that play. Once you understand that rhythm, rulebook differences become details rather than barriers to enjoying the game.

Frequently Asked Questions
Are international American football games played under NFL rules?
Not necessarily. NFL games abroad use NFL rules, but IFAF tournaments generally use IFAF rules based on the NCAA game. The location alone does not determine the rulebook.
How many players are on the field for each team?
In the standard game, each team has 11 players on the field at a time. Substitutions are generally made while the ball is dead, subject to the competition’s rules.
Is the scoring different in IFAF football?
The familiar scoring values apply: six points for a touchdown, three for a field goal, one for a successful extra-point kick, two for a successful two-point try and two for a safety. Specific procedures can vary by competition.
Do all international leagues use exactly the same rules?
No. IFAF rules provide a common international framework, but leagues and tournaments may have their own regulations or age-group adaptations. Check the rules for the competition you are watching.
Final Thoughts
International American football keeps the sport’s central logic intact: advance 10 yards in four downs, score in the end zone or through the uprights, and win the field-position battle. The main thing to remember is that “international” describes where and under whose authority the game is played—not one universal set of rules. Identify the competition first, and the calls on the field make much more sense.
