Why do soccer games end in ties?

Soccer is built for tight scorelines. A big field, ninety minutes of running, limited substitutions, and goals that arrive fewer than three times a game on average.

When scoring is that scarce, two evenly matched teams finishing level isn't a failure of the format. It's the most likely outcome.

One point each, against three for a win. That single point sounds like nothing and decides seasons.

A team that draws fifteen games has thirty points from those games alone, which can be the difference between finishing safely and being relegated. This is why you'll see a team defending desperately in the final minutes of a game they're drawing. They're not playing for nothing. They're playing for a point.

It's also why “we'll take a draw” is a genuine tactical position rather than a lack of ambition.

Knockout competitions need somebody to advance. If a game is level after ninety minutes:

Extra time. Two halves of fifteen minutes. Thirty more minutes of soccer, played by players who have already run themselves into the ground.

Penalties. Still level after 120 minutes and it goes to a shootout. Each team takes five kicks from the spot, alternating. Most goals from those five wins.

Sudden death. Still tied after five each? One kick at a time until one team scores and the other misses.

The 2022 World Cup final is the textbook example. Level at 2-2 after ninety minutes, both sides scored again in extra time to make it 3-3, and Argentina won 4-2 on penalties.

European knockout rounds are played over two games, one at each stadium. The scores are added together, which is called the aggregate.

Level on aggregate after both games and you're straight into extra time and penalties, same as anything else.
