Offside is the most complained-about call in soccer, and it's also the most misunderstood. Here's the version that will make you nod your head.

The Simple Version

When a teammate passes you the ball, you cannot be ahead of the last defender (not counting the goalkeeper) at the moment the ball is kicked. You have to be "onside" — even with or behind that last defender — when your teammate's foot hits the ball.

What It Is Not

Offside is NOT called when you receive the ball directly from a corner kick, throw-in, or goal kick. It's also not about where you are the whole game — only where you are the instant the ball is kicked to you.

Why It Causes So Much Controversy

With VAR technology, referees can review whether a player's shoulder, armpit, or big toe was a few inches offside. This leads to goals being disallowed by margins so small they require a freeze-frame and drawn lines to see. It is technically correct. It is also maddening.

VAR stands for Video Assistant Referee. It was introduced to catch clear errors in four specific situations: goals, penalty kicks, red cards, and mistaken identity.

How It Works

A separate team of officials in a video review room watches the game on multiple camera feeds. If they spot a potential error in one of those four categories, they can alert the on-field referee. The referee can then review the footage on a pitch-side monitor or simply accept the VAR team's recommendation.

Why It Takes So Long

VAR pauses are frustrating because soccer has no natural stoppages like American sports. The referee has to halt an active game while the review happens. And because the technology can zoom in to pixel-level detail on offside calls, a 15-second play can trigger a 3-minute review.

The Controversy

The debate isn't really about the technology — it's about where to draw the line. Stopping a game for 4 minutes to rule a goal offside by a player's armpit is technically correct but ruins the experience. FIFA continues to adjust the guidelines.

The World Cup starts with a group stage: 32 teams split into 8 groups of 4. Every team plays the other 3 teams in their group once. The top 2 from each group advance to the knockout rounds.

The Points System

Win = 3 points. Draw = 1 point each. Loss = 0 points. After 3 games, the two teams with the most points advance. Simple — until you get a tie.

Tiebreakers

If two teams finish with the same points, the tiebreaker order is: (1) Goal difference — how many more goals you scored than allowed. (2) Total goals scored. (3) Head-to-head record. (4) Head-to-head goal difference. Then it gets into fair play points (yellow and red card counts), and ultimately a drawing of lots.

Why a 0-0 Draw Can Be a Great Result

A draw gives both teams a point. If you're the underdog against a powerhouse, earning a point against them while the other two teams in your group play each other can be a tournament-saving result. Context matters enormously in the group stage.

Once you're in the knockout rounds, there's no such thing as a draw. Someone has to go home. Here's what happens.

Extra Time (30 Minutes)

If it's still tied after 90 minutes, both teams play two additional 15-minute periods — 30 minutes total. Players are exhausted. Cramps are everywhere. Substitutions are used strategically to get fresher legs on the field.

The Penalty Shootout

Each team picks 5 players. They take turns shooting from the penalty spot (12 yards from goal) with only the goalkeeper to beat. Whoever scores more of their 5 kicks wins. If still tied after 5 each, it goes to sudden death — alternating kicks until one team misses and the other scores.

Why It's So Brutal

A penalty kick is converted roughly 75-80% of the time under normal conditions. Under World Cup knockout pressure, with 60,000 people watching and your country's elimination on the line, that number drops. The goalkeeper guessing the wrong way, a slight mistrike, nerves — any of it ends your tournament. It is the purest high-pressure moment in team sports, decided essentially by individuals.

Soccer's rules are governed by IFAB (International Football Association Board), not FIFA. They update the Laws of the Game regularly. Here are the changes most relevant to watching the 2026 World Cup.

1. Five Substitutions Per Game

For most of soccer history, teams could make only 3 substitutions per match. That changed during COVID and stuck. Teams can now make up to 5 substitutions, with a maximum of 3 stoppages to do so (plus halftime). This significantly changes late-game tactics and squad management.

2. Handball Rule Clarification

If a goal is scored immediately after the ball accidentally touches an attacker's hand or arm — even if the player didn't intend it — the goal is disallowed. "Unintentional" no longer gets you off the hook if you benefit directly.

3. Encroachment on Penalties

If a goalkeeper moves off their line too early during a penalty and the kick is missed, the kick is retaken. This is now enforced much more strictly with VAR. It has led to several high-profile penalty retakes.

4. Concussion Substitutions

Teams now get an additional substitution specifically for suspected concussions, which does not count against their 5-sub allowance. It's a significant player safety improvement.

5. Time-Wasting Crackdown

Goalkeepers are now limited to 8 seconds when holding the ball (down from 6, though enforcement was previously lax). Referees are also instructed to add more accurate stoppage time — which is why you're seeing 10+ minutes of added time in matches where previously it might have been 4 or 5.
