What it does
The Round Robin Scheduler builds complete tournament schedules using the classic circle method: every participant meets every other participant exactly once, in balanced rounds. Three modes cover the common shapes — pairings (traditional match-ups per round), rotation (sequential/elimination-style order), and seating arrangements. Seeded, so the schedule can be republished identically.
Common use cases
- Sports and esports leagues — a full season schedule where everyone plays everyone, generated in one click.
- Chess and board game clubs — balanced round pairings without a spreadsheet evening.
- Meeting rotations — 1:1 pairing schedules where every team member meets every other over N sessions.
- Speed networking and classrooms — seating rotations that cycle everyone past everyone.
Settings
- Players — one per line; odd counts are handled with a bye each round.
- Schedule mode — pairings, rotation, or seating.
- Seed — randomizes the initial arrangement reproducibly; the same seed and list regenerate the identical schedule.
Privacy note
Schedules are computed locally in your browser — participant lists are never uploaded. Output is exportable as CSV, JSON, NDJSON, TSV, or Markdown for sharing and printing.
FAQ
How many rounds will I get? n−1 rounds for an even number of participants, n for odd (everyone sits out exactly once via the bye). Each round pairs everyone simultaneously — that’s the circle method’s guarantee.
What does the seed change? Which pairings land in which round — the structure (everyone meets everyone once) is invariant; the seed just shuffles the order fairly.
Single-elimination instead? That’s the Bracket Seeder — random first-round draws with byes. Round robin is for “everyone plays everyone”; brackets are for “lose and go home.”
