There are 64 matches in the World Cup, including 48 group matches, 8 finals in 1/8, 4 finals in 1/4, 2 semi-finals, 3-4 finals in 1 game, and 3 rd and 4 th runner-up finals in 1 game. The team that scored more goals within 90 minutes (including stoppage time) in the knockout stage won. If the two sides can't decide the winner within 90 minutes (including overtime), the first half and the second half will play 15 minutes overtime respectively. In the overtime stage, if the two teams are still tied, it will be decided by the penalty of the players from both sides. In principle, the penalty kick is that each side kicks five balls. If it is still a draw, both sides will play a ball and the winner will win. If there is still no tie, the penalty will continue and both sides will kick another ball until the tie is broken.
