Next Rally
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.

Live standings
Smoothed win rate · ties share a rank
New · game type
Run it as a team tournament.
Same club, same phones, a different night. Split into teams, play a fair round-robin across every court, then settle it with a knockout final. Every result still feeds the same player rankings and ratings.
Teams of three
Run 4, 6 or 8 teams across 2 to 4 courts. Drag players between teams to balance them, then give each team a name and a photo.
A fair round-robin
Every team meets every other. Each meeting is three short capped games so all three partner combinations play, pinned to a court so nobody hunts for where they are next.
Knockout finish
Cap the league with an optional final and 3rd-place playoff, so the night ends on a real decider instead of a spreadsheet.
Members set line-ups
Each team arranges its own pairs for the coming games from their phones, dragging a pair to a different game. Coordinators can step in too.
Live on every phone
The same shared board shows every court colour-coded with team standings updating in real time, and control hands over cleanly if the host changes.
Counts like any game
Wins, losses and scores roll into each player's stats, session ranking and long-term rating. A tournament is never a side show.
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.
