Live scoring
Simple enough to score one-handed
The console is two big buttons and a scoreboard. Everything a badminton umpire actually needs is one tap away, on the same phone they’re already holding.
- +1 per rally — serve passes to the rally winner automatically.
- Undo any point when a call gets reversed.
- End set early when time runs out; the leading side takes it.
- Rally-by-rally timeline recorded for every game.

Broadcast overlays
Graphics your stream deserves
Every arena gets its own overlay URL. Paste it into an OBS browser source — the page is fully transparent, so only the graphics land on your feed.
- Lower-third scoreboard while a match is live, full-screen result when it ends.
- Idle rotation — tournament board, latest result, full scorecard, or your own sponsor image.
- Trophy screens — champion, their journey, fixture path and profile.
- Four themes and a “show now” button to push any screen instantly.
Overlay control — per-arena URLs, themes, and the screens that rotate while no match is on court.

Before you start
Do spectators need an account?
No. Tournament pages, fixtures, scorecards and player lists are public. You only sign in to host or score.
How do the overlays work with OBS?
Add a browser source pointing at your arena’s overlay URL. The overlay page renders with a transparent background, so only the scoreboard and full-screen graphics appear over your camera feed.
Can several people score at once?
Yes. Add collaborators to a tournament with can edit and they can run matches alongside you; can view gives read-only access from their dashboard.
Which sports are supported?
Badminton is enabled today — games to 21 (or 15 / 30), best-of 1/3/5, singles and doubles. Tennis and table tennis sit in the same sport registry, ready to switch on.
What do I need to install?
Nothing. GameOn runs in the browser — phones for scoring, a laptop for the control room.
