Badminton Scoring

Geilio Scoreboard follows official BWF (Badminton World Federation) rules so you can focus on the game instead of keeping track of points, serves, and sides.

How a Match Works

A standard badminton match is played as best of 3 sets, with each set going to 21 points. The first player or team to win two sets takes the match. Geilio Scoreboard tracks everything automatically -- just tap the point for whoever scored, and the app handles the rest.

Singles and Doubles

When you start a badminton match, choose between singles (one player per side) or doubles (two players per side). Geilio Scoreboard adjusts its serve and position tracking depending on the format you select.

Serve Tracking

In badminton, the serve always follows the scorer. When you win a rally on your serve, you keep serving. When your opponent wins the rally, the serve passes to them. Geilio Scoreboard tracks this for you -- after every point, the display clearly shows who is serving next. No more mid-game debates about whose turn it is.

How the server's side is determined: When the serving player's score is even (0, 2, 4...), they serve from the right court. When the score is odd (1, 3, 5...), they serve from the left. Geilio Scoreboard tracks this rule automatically. In Settings you can turn on the serve indicator (free) to mark which side is currently serving, and in doubles you can enable the advanced serve indication (Pro) to also show exactly which player is serving and from the left or right side.

Doubles Positioning

Doubles scoring adds a layer of complexity that Geilio Scoreboard simplifies. When the serving team scores consecutive points, the two players on that team swap positions (left to right, or right to left) before the next serve. If the serve passes to the other team, no swap occurs -- the receiving team's positions stay the same.

With advanced serve indication enabled (Pro) in doubles, Geilio Scoreboard shows the current left/right position of each player so your team always knows who stands where and who serves next. (This detailed positioning display isn't shown in singles.)

Deuce Rules

When the score reaches 20-20, regular play is over and deuce rules kick in:

• A player or team must win by a 2-point lead to take the set. So 22-20 wins, but 21-20 does not.
• If the score reaches 29-29, the cap comes into effect. The next point wins the set at 30-29 -- no further extension.

Geilio Scoreboard applies these rules automatically. You will see a "Deuce" indicator on screen when the game enters this phase, and the app will correctly end the set as soon as the winning condition is met.

International Announcement Mode

If you've turned on voice announcements (a Pro feature, iPhone only), you can switch badminton's "announcement mode" from Default to International in Settings so the spoken calls sound closer to how a referee announces in official matches.

• In International mode, the app calls the score in the international order of "server's score -- receiver's score," and uses the standard competition phrasing for the start of play, match point, and the end of a game.
• When a point causes the serve to change hands, the app announces "serve change" along with the current score first, rather than leading with the side that scored -- matching how referees call a change of serve.
• Default mode uses more conversational phrasing instead.

Both modes only affect the wording of the voice announcements; neither changes any scoring rule.

What Geilio Scoreboard Handles for You

Here is a summary of everything Geilio Scoreboard manages during a badminton match:

• Point counting up to 21 per set, best of 3 sets
• Serve assignment after every rally, following the scorer
• Court side indicators based on even/odd score
• Doubles position swaps on consecutive serves
• Deuce detection at 20-20, requiring a 2-point lead
• 30-point cap at 29-29
• Set and match completion when the winning conditions are met

All you need to do is tap the score for the player or team that won the rally. Geilio Scoreboard takes care of the rest.
