Tournament name

Shown as the title on every page and used to build the tournament address. You can change it while the tournament is a draft.

Activity

Optional. What is being played, shown next to the tournament name exactly as you type it.

Organizer name

Optional. Shown on public pages as who is running this tournament. Leave it blank and no organizer is named.

Visibility

Who can reach the tournament pages. You can change this while the tournament is a draft.

PublicListed on the Arena index and open to anyone who has the address. UnlistedOpen to anyone who has the address, but never listed on the index and never added to search or the sitemap. PrivateA read link is required even at the direct address. Anyone without one gets a not-found page that does not reveal whether the tournament exists.

Format

How entrants are paired and how the tournament ends. The format decides which settings appear below and which views the tournament pages lead with.

Single eliminationOne loss ends a run. Produces a bracket and the fewest matches for a given field. Round robinEveryone plays everyone. Produces a standings table, and the number of matches grows quickly as the field grows. SwissA fixed number of rounds, with entrants paired by current score. Nobody is eliminated early, and the result is a standings table. Groups, then playoffA group stage produces tables, then the entrants who qualify play a bracket. The tournament pages change emphasis when the stage changes.

If the standings are still tied

Arena uses points, wins, game difference and head-to-head first. This choice applies only if those still leave an exact tie after all matches are played.

Use the starting orderThe lower starting seed ranks first. No additional draw opens. Run a separate drawArena opens a draw for only the tied entrants. Their final order waits for that ceremony; the fairness setting determines the evidence it carries.

Entrants

No entrants yet. Paste or type the names, one per line.

One name per line. Paste a list or type it. Names are shown exactly as written and are never translated, so spelling here is the spelling everywhere.

How the draw is made

Pick one. You can still change it while the tournament is a draft, but not after the draw has run.

Sealed random draw, bound to a public beaconArena commits to the draw first, then binds it to a public randomness round published after that commitment. The order cannot be known or picked in advance.This covers the draw order only, not results, refereeing or scoring. Without an independent notary, the fact that only one commitment was made rests on the BearMark record alone. Manual orderYou set the order yourself or import it. Arena records that order and replays it exactly as recorded.A manual order carries no unbiasability claim. A successful replay shows the recorded order was applied unchanged; it does not show the order could not have been chosen to favour someone.
