The current scoring system in badminton is the 3 × 21 rally point scoring system. This means that three games (i.e. one match) are played to 21 points each, with a required two point difference between scores (meaning scores can go above 21, to a maximum of 30). The winner of a rally scores a point regardless of who served. This scoring system was adopted from August 2006 by the International Badminton Federation, now known as the Badminton World Federation (BWF).
