how may points do you need to win a game in badminton?

In badminton, to win a game you need to be the first player or team to reach 21 points, provided you have at least a two-point lead over your opponent. If the score reaches 20-20, the game continues until one side gains a two-point advantage, such as 22-20 or 25-23. However, if the score reaches 29-29, the next point (the 30th point) wins the game, making 30 the maximum points possible in a game. Matches are typically played as the best of three games, so winning two games wins the match
