CONTENDER OS

Contender OS — the league-night operating system.

League nights that run themselves. Contender OS takes signups, starts the night on schedule, collects player-reported results backed by photo proof, settles disputes by published automatic rules, builds the standings, queues the payouts, runs the live TV board, and packages the night into a media kit when it's over.

I'm an operator — keep me posted

No staff work. No league secretary. No paperwork.

A night runs start to finish, on its own

The venue's only job is having a crowd. Contender OS handles every step that used to need a person with a clipboard, a bracket printout, and a group chat.

STEPSignups take themselves Players register and pay entry online, pick their venue and night, and land on the roster in order.

STEPThe night opens itself At start time the system seeds the field and opens the bracket. Under the minimum, the night holds instead of paying out.

STEPPlayers report, photos prove Both players report the result from their phones. A score photo backs it up. Agreeing reports confirm instantly.

STEPDisputes rule themselves Published auto-rules decide conflicts from the photo evidence — no staff member settles anything, ever.

STEPStandings and payouts queue up Points post to the season standings as results confirm, and the payout queue is built the moment the night ends.

STEPThe night markets itself A live TV board runs in the room all night, and a media kit with results and highlights is ready when the night closes.

One system for every league night in the building

If it has players, a schedule, a score somebody can report, and a standing somebody cares about, Contender OS can run it.
