Badminton Match Probability Calculator

Builds the exact Markov chain of 21-point rally scoring badminton from one number per player — the probability of winning a rally on own serve — with the winner-serves-next rotation, the win-by-2 extension and the golden point at 29-29. Computes game odds, best-of-3 match odds and the game-score distribution.

0.03
How much winning a point boosts the winner’s chance on the next one. 0 behaves like independent points; 0.03 is a moderate, realistic level; 0.1 produces heavy streaks.

Notes

  • Rally scoring means the serve gives only a small edge in badminton — typical serve-rally win rates sit close to 50%.
  • The winner of a game serves first in the next one; the model averages over the opening toss.
  • Educational estimate for sport and training purposes, not professional coaching or medical advice.
