1 The desk
Set up divisions and the draw, then let it run: courts fill themselves and the playoff seeds itself. Invite a co-organizer or desk helpers to run it with you from their own devices, and step in any time: change a match, record a walkover or fix a score.
2 Players
Each player scans their own QR code: their court and opponent, a rest countdown with “We’re ready”, score entry the other team confirms, where they rank in the division, and a medal if they make the podium.
3 The venue
Put it on a TV: each new call announced, who’s playing on which court, up next and podiums as they’re decided. Friends and family follow from anywhere.
