World Cup Rules Explained for Americans (Offside, VAR, Extra Time)
Coming to soccer from American sports? Almost everything maps onto something you already know — except the clock, which works backwards from what you'd expect. Here's the whole rulebook, fast.
Start with the clock, because it’s the weird one
In the NFL, NBA, and MLB, the clock stops constantly and the game ends when it hits zero. Soccer does the opposite:
- The clock counts up from 0:00 to 90:00, in two 45-minute halves.
- It never stops — not for fouls, not for the ball going out, not for injuries.
- Time lost to stoppages is added on at the end of each half as “stoppage time” (a few minutes), announced by the fourth official.
So a game listed as “90 minutes” actually runs closer to 100 of real time, and there are no timeouts. Get this one thing and the rest is familiar.
Scoring
One goal = one point. Final scores are low (1–0, 2–1) because scoring is genuinely hard. A 0–0 can still be a great game. There’s no equivalent of a field goal or a three-pointer — every goal is worth exactly one.
Offside
The rule US fans trip over most. Short version: an attacker can’t be nearer the goal than the last defender at the moment the ball is passed to them — it’s an anti-goal-hanging rule, like the playground “no cherry-picking” convention in basketball.

VAR (instant replay, with limits)
Soccer’s replay system, VAR, only reviews four things — goals, penalties, straight red cards, and mistaken identity — and only overturns clear and obvious errors. It’s narrower than NFL replay. Details in what is VAR.
Cards: yellow and red
- Yellow card = a caution. Two yellows in one game = a red.
- Red card = ejection. The player is gone and cannot be replaced — the team plays the rest of the match a man down. There’s no penalty box; the disadvantage is permanent for that game.
Yellows also carry across matches and trigger suspensions, which we’ll cover in the tournament discipline guide.
Substitutions
Each team gets five substitutions per match (in three stoppages). Unlike basketball, a substituted player cannot return — once you’re off, you’re off for good.
Ties, extra time, and penalties
- Group stage: a tie is a legal result. Both teams take a point. (Yes, really — no overtime.)
- Knockouts: there must be a winner. A tie after 90 minutes goes to 30 minutes of extra time, and if it’s still level, a penalty shootout decides it. The full mechanics are in the knockout rounds explained.
That’s the whole rulebook
Clock counts up, ties are fine in groups but not knockouts, red cards leave you short-handed, and offside stops goal-hanging. Master those four and you’ll follow any match. New to the tournament’s structure too? See how the World Cup works.
