Soccer is the world's most popular sport, and while its basic rules are simple, there can be confusing moments for first-time viewers. This guide is written for anyone who wants to understand soccer well enough to enjoy the 2026 World Cup — whether you want to play a pool with your family or are simply curious.
The Goal of the Game
Soccer is played between two teams of 11 players each. The objective is simple: get the ball into the opposing team's goal more times than they get it into yours. At the end of the match, the team with the most goals wins. If both teams finish with the same number of goals, the match ends in a draw — something very common in soccer, unlike other sports.
Match Duration
A soccer match consists of two 45-minute halves, with a 15-minute break in between. However, the referee can add extra time at the end of each half — called 'stoppage time' or 'injury time' — to make up for minutes lost to injuries, substitutions, goal celebrations, and other delays. In knockout rounds, if the match is tied after 90 minutes, extra time is played (two 15-minute halves), and if still tied, there is a penalty shootout.
The Goalkeeper: The Only One Who Can Use Hands
In soccer, no field player can intentionally touch the ball with their hands or arms during play (they can use their chest, thigh, head — any body part except arms and hands). The goalkeeper, however, can catch, punch, or throw the ball with their hands, but only within their own penalty area (the large rectangle in front of their goal). If they leave that area, they must play like any other player.
Fouls, Free Kicks, and Penalties
A foul occurs when a player commits an infraction: pushing a rival, kicking without intent to play the ball, shirt-pulling, etc. The team that was fouled gets a free kick from the spot where it occurred. If the foul happened inside the offending team's penalty area, the affected team gets a penalty kick: a direct shot from 11 meters with only the goalkeeper between the player and the goal. Penalty kicks are converted approximately 75–80% of the time.
Cards: Yellow and Red
The referee uses cards to discipline players. A yellow card is a caution: if a player receives one, they are warned. If the same player receives two yellow cards in the same match, they automatically receive a red card and are sent off the field. A red card can also be given directly for a serious foul (like a violent tackle or assault). A team with a player sent off must play the rest of the match shorthanded — a massive disadvantage.
Offside
Offside is soccer's most debated rule. In simple terms: an attacker is offside if, at the moment their teammate touches the ball to pass it, they are closer to the opposing goal than the second-to-last defender of the opposing team (usually the last outfield defender, since the goalkeeper is typically the last one).

💡 Quick tip: Soccer rewards patience and strategy. Teams can go long stretches without scoring, which makes every goal an explosion of emotion. That's how soccer captures the world!
