The 15 game rally format is still the preferred format played in badminton. When not in tournament, it is still okay to follow this format and not the official one. Listed are the basic badminton rules for a 15 point game.

In men’s match: When the score ties to 14-all, the side that scored 14 first shall have the choice either continue playing to 15 or to set the badminton game to 17 points.
In women’s match: When the score ties to 10-all, the side that scored ten first shall have the choice either continue playing to 11 or to set the badminton game to 13 points. Only the side that served can win a point. If you win in which the other side served, you just win back the turn to serve but not add points to you game. In singles: when the score if an even number, serve right of the service court; when the score if an odd number, serve left of the service court. In doubles: when you serve and received on the right side if the service court first, you will continue during the match to serve on the same side when your opponent’s score is an even number. As basic badminton rule, your partner’s pattern is reversed.
