King of the court: rules for badminton and pickleball open play
Winners stay, challengers line up. The rules, the multi-court ladder, and the one setting that decides whether it works: the cap.
By Albert Antioquia · Updated
King of the court is the format where the winners stay on and the next pair challenges them. Some clubs call it a challenge court or challenger’s court, some call it winners stay, and pickleball groups often say queen of the court. It is fun, fast and competitive. Run without a cap, it is also the quickest way to empty a bench. This guide covers the rules for badminton and pickleball doubles, the multi-court ladder version, and how to choose the cap.
The basic rules (one court)
- Two pairs play one game. Short games work best: to 11 in pickleball, to 15 or 21 in badminton.
- The winning pair stays on court.
- The losing pair goes to the back of the line, and the next pair in line comes on.
- A pair that wins a set number of games in a row (the cap) leaves the court anyway, and two new pairs come on.
The line is made of pairs, not individuals. Decide up front whether pairs are fixed for the night or re-formed each time a player comes off; re-forming keeps partners mixed.
Why the cap matters
Without a cap, a strong pair can hold the court for an hour while everyone else plays once. With a cap of k, the longest any pair can stay is k games, and the court turns over at least every k games. The table shows what that means for the person waiting:
| Cap | Longest stay on court | Feels like |
|---|---|---|
| 1 | 1 game | Ordinary rotation: winners come off too |
| 2 | 2 games | Competitive but moving; a good default |
| 3 | 3 games | Rewards a hot streak; fine for small, even groups |
| No cap | Unlimited | Only for a group that has agreed to it |
Pick the cap by group size. With one or two pairs waiting, a cap of three is fine because everyone gets back on soon. With a long line, use two, or switch to a rotation where all four come off after every game.
The ladder: king of the court across several courts
With three or more courts you can run the version pickleball groups call up river, down river (also ladder or waterfall). Courts are ranked, with the top court as the “king” court. After each timed round, winners move up one court and losers move down one. Winners on the top court stay; losers on the bottom court stay. Partners usually split after every round, so each player rises or falls on their own results.
The ladder sorts a mixed group by level within a few rounds without anybody having to rate anybody. It needs a fixed head count and everyone ready at the end of a round, so it suits a planned session better than a drop-in open play.
Badminton vs pickleball differences
- Game length. A badminton game to 21 runs much longer than a pickleball game to 11. On a winners-stay court in badminton, use games to 15 or 11 so the line moves.
- Serving on. In pickleball, agree who serves first when a challenger pair comes on (the challengers is the usual answer). In badminton, a quick rally for serve works.
- Fatigue. A long run on a badminton court is tiring; a cap of two protects the winners as much as the bench.
When not to use it
King of the court rewards the strongest players. In a group with a wide spread of levels, newer players lose their one game and go back to the end of the line, which is the opposite of what keeps them coming back. For mixed groups, a rotation that balances levels and games played is fairer; see how to balance skill levels in open play. A good compromise is one challenge court for those who want it, with every other court on a normal rotation.
Running it in PaQueueKa
PaQueueKa has this format built in as Challenger’s Court, one of the rotation modes for Pro Hosts. Winners hold the court and rotate off after the run of straight wins you set, and players see on their phones who is next. The free PaQueueKa Rotation is the balanced alternative. The rotation modes page compares all three.
Questions people ask
What is king of the court?
A format where the winning pair stays on court and the next pair in line challenges them. The losing pair goes to the back of the line. Most groups cap how many games in a row the winners can stay.
What is a good win cap?
Two consecutive wins is a good default when several pairs are waiting. Three works for small groups of similar level. Without a cap, a strong pair can hold the court all night.
Is king of the court the same as up river, down river?
They are related. Up river, down river is the multi-court version: courts are ranked, winners move up a court and losers move down after each round, and partners usually split every round.
