World Cup extra time rules explained. Is there golden goal?

In the group stage of the World Cup, games can end in ties.

But what happens when play advances to the knockout round?

Elimination games obviously can't end in ties, so play advances to extra time (which is more known as overtime in typical American sports). The 2022 World Cup final was decided in unforgettable fashion when Argentina defeated France in penalty kicks after a back-and-forth extra time.
