Check the competition’s scoring format before using a badminton guide. Simplified guides often describe the traditional best-of-three, 21-point system. During the current scoring transition, the event’s stated format is the reference for the game being played.
Badminton BC’s published overview explains the traditional system. Badminton Canada’s competition memo specifies best-of-three games to 15 from September 2026, with stated exceptions. This article uses the traditional format for the numerical example; use your event’s regulations for its game target and cap.
A doubles practice sheet is easier to follow with the four players named at the top. The score and current server can then be recorded after each rally. Those names provide a steady reference as the serving and receiving roles change.
Understand the rally first
Under the traditional rally-scoring example, the side winning a rally adds a point. In singles, an even serving score places the server on the right; an odd serving score places the server on the left. The receiver stands diagonally opposite.
An invented singles sequence starts at 0–0 with the server on the right. If that player wins, the score becomes 1–0 and the next serve is from the left. Use the serving player’s score to identify the relevant service court.
Keep doubles positions on paper
In the simplified doubles system, when the serving side wins a rally, the same server serves again from the other service court. When the receiving side wins, it becomes the serving side. Players do not swap their respective service courts merely because they received a point.
Draw four named player markers and update the score after each fictional rally. Keep player names or initials beside the changing server and receiver roles.
Verify the finish separately
Write the game target, deuce rule and cap beside your diagram from the event’s published conditions. That prevents a correct service-order exercise from carrying an outdated assumption about when the game ends.
Follow a singles example
Under the traditional format used for this teaching example, imagine the server has six points. The even score places the serve in the right service court. Winning the next rally makes the score seven and the same player serves from the left. If the receiver wins the following rally, that player becomes the server and uses the court appropriate to their own score.
Keep both scores visible throughout the exercise. The service-court choice follows the current server’s score, which may differ from the player who served the previous rally.
Distinguish service courts from the finish rule
In the traditional 21-point example described by Badminton BC, 20-all continues until a side leads by two, with the stated cap deciding the point at 29-all. A sequence of 20-all, 21-20 and 21-all therefore continues; 22-20 would complete that game.
The event’s actual regulations remain the reference during the scoring transition discussed above. Put the format beside the score sheet before applying a numerical finish example.
For doubles practice, keep names and their current service courts on a separate sketch. Update one rally at a time, following the documented change of service. This helps distinguish the team score, the individual due to serve and the service court from which that player serves.
For a learning exercise, pause at one service change and follow it on paper before continuing the game. Working through a single transition gives both partners time to connect the score with their positions. The event’s scoring format belongs beside the example as a reference.
