Court Shuffle Pro
Game night,
without the whiteboard.
Next Rally runs your club's badminton (or tennis, pickleball, padel) sessions: fair court rotations every round, live scores on every phone, and rankings that write themselves.
The flow
A game night in six moves.
- 01
Schedule
A coordinator creates the game night for a group — date, time, venue.
- 02
RSVP
Members tap In or Out from their phones; WhatsApp nudges chase the quiet ones.
- 03
Check in
At the hall, players mark themselves Here; drop-ins and guests join the roster.
- 04
Shuffle
The engine deals fair courts each round — equal play, fresh partners, honored rests.
- 05
Play & score
Each court records its own winner and score; every phone stays live.
- 06
Podium
End the night with rankings, a shareable podium, and ratings that update club-wide.

Who does what
One app, three hats.
Turn up, tap in, play more.
Everything a club player needs on one phone: answer the game invite, check in at the hall, watch the live court board, and track how your game is trending — no spreadsheets, no group-chat chaos.
The engine
Fairness you can measure, not just promise.
Every shuffle searches ~1,200 candidate line-ups and keeps the fairest. The rules below are continuously verified with Monte-Carlo simulations of full club nights.
≤ 1
game difference
Across a full night, the gap between who played most and least is at most one game.
0
repeat partners back-to-back
The same 2v2 partnership never repeats in consecutive rounds — verified across thousands of simulated sessions.
0
double benchings
Nobody rests two rounds in a row. Resting follows games played, so breathers rotate naturally.
75×
less repetition than random
Court-mate repeats happen ~0.25% of the time vs ~19% with naive random shuffles.
