Everything you need to know

The Rulebook

Opening a card

• Anyone can open one. There is one card at a time, championship-wide.
• The promoter picks a world, a venue, what is at stake, and how long the doors stay open — 1, 3 or 5 minutes.
• The format is the house’s and is announced at the bell.
• A card holds the arena from its doors opening until its last line has been on screen. Nobody can open another until it finishes.

Entering

• Anyone who owns a hoodie can enter any card. Unlocks and membership never gate entry.
• Enter as many hoodies as you like. Each one appears once.
• A free card with only one entrant is padded with house hoodies so it still runs. A card with money on it is never padded, and does not run without a real field.

The fight itself

• Cull — on a large field the arena removes many at once, by something they have in common. Skipped on a small card.
• Rounds — eliminations one at a time until two remain.
• The finish — the last two settle it. One walks out.
• The entire card is resolved in one go and then played back at reading speed, so every viewer is on the same beat.

• Nothing you buy or earn makes a hoodie harder to beat. Not levels, not prestige, not weapons.
• Five stats are derived from the hoodie’s class and ink: power, guard, speed, luck, heart.
• Survival is guard, heart and speed. Being credited with an elimination is power and luck.
• Each round is 70% those numbers and 30% chance, so nothing is a foregone conclusion.
• Rarity does not touch a single number. A floor hoodie beats a grail as often as the other way round.
• Class is the largest factor, and the four go in a cycle: Builder beats Collector, Collector beats Flipper, Flipper beats Hodler, Hodler beats Builder.
• Ink moves a hoodie between armoured and quick. Across the whole ink range it shifts a win rate by a few points, not by an order.
• There is no strictly better hoodie — only one that matches up well against whoever turned up.

Earning

• Entering: 10
• Each round survived: 6
• An elimination: 30 — and 15 more each for a multikill
• First blood: 20
• Surviving a Cull: 8
• Reversing a kill onto whoever tried it: 40
• Finishing first / second / third: 150 / 80 / 50
• All of it multiplied by field size, so a big card is worth far more than a small one.

Where it goes

• Stored against the tokenId, not a wallet — a record survives a sale.
• Costs nothing. No membership, no purchase, no sign-up.
• Levels come from lifetime XP earned, so spending never demotes you.
• Fight on consecutive UTC days for a streak multiplier.

• Free — no entry, nothing at stake, everything still counts.
• Wager — everyone stakes the same. The winner takes most of it.
• Sponsored — one person funds the prize, everyone else enters free.

Free fight

• No entry. Records, XP, ladders and belts all count exactly the same.

Wager fight

• Every entrant pays the same wager, in $OCH, set by the promoter.
• 75% to the winner, 25% to that week’s Main Event pot.
• UHC takes no share of any pot.
• Needs at least two paying entrants. Below that it does not run and stakes are returned.

The wager ladder

• Suggested — 100, 250, 500, 1,000 $OCH
• Degen — 1,500, 2,500, 5,000, 10,000 $OCH
• Brain damage — 100,000, 1,000,000 $OCH · requires a confirmation before the card opens
• For scale: 1,000,000 $OCH is one per cent of the entire supply.

Sponsored fight

• A sponsor puts a jackpot up. Everyone else enters free.
• The sponsor’s hoodie presents the card and is named by the booth throughout.
• Payout table chosen by the sponsor: Winner takes all, 60 / 40, 50 / 30 / 20, Deep table.
• If fewer places finish than the table pays, the unpaid shares are redistributed in proportion, keeping the shape the sponsor chose.
• A minimum field, set by the sponsor (default 4). Below it the card does not run and the jackpot is returned.
• Neither UHC nor the Main Event pot takes a share.

• A fourth kind of card, and the only one no promoter can open — the house schedules it.
• One card a week, at a fixed time.
• Free to enter, members only, and every member is entered automatically.
• Funded by the 25% taken from that week’s wager fights.
• An empty pot never pays out — it rolls into the following week.
• The card runs regardless. Every member, every week, pot or no pot: the belt is the prize and the money is a bonus.
• Its winner takes the UHC Heavyweight belt.
• A non-member entering a wager fight funds a pot they cannot win. Every card carrying a wager states this before entry.
• It is an ordinary numbered card carrying a flag, not a separate competition — same sequence, same record.

Titles — won in a fight

• UHC Heavyweight — winner of the weekly main event
• UHC Welterweight — winner of the last card
• UHC Sponsor's — winner of the last sponsored card
• Undisputed — held the heavyweight and welterweight at once

No. 1 contenders — a ranking

• One per class: Builder, Collector, Flipper, Hodler.
• Held by whoever is top of that class on XP. Not won off anybody, and there is no lineage.

Prestige

• Available at level 25, which is roughly a hundred cards.
• Resets you to level one and keeps the rank.
• Opens the highest tier of gear.
• Carries no combat advantage of any kind.

What membership is

• 1,000 $OCH, paid once. Not a subscription and it does not lapse.
• The fee goes to the UHC treasury and is the only money UHC takes — which is what lets it take no share of any pot.
• Per hoodie, not per wallet. Twenty hoodies is twenty memberships.
• It belongs to the hoodie, so it survives a sale along with the record.
• It is never required to fight, and never required to be recorded.

What it buys

• Entry to the weekly Main Event — automatic, no signup.
• The right to hold a belt. A non-member can enter anything and win anything, including a pot — they cannot hold a title and are not in the weekly.
• The shop: worlds, armouries beyond the free kit, finishers and prestige.
• Presenting cards in worlds past the free one.

The shop

• XP earns the right to a tier; membership keeps it live.
• Worlds — the right to present a card in one, never to enter one.
• Armouries — the weapons of a world, tier by tier.
• Nothing sold anywhere affects who wins a fight.

• The Hood — 12 venues, 18 weapons, 4 of them free to wield
• Deep Space — 5 venues, 9 weapons, 3 of them free to wield
• Medieval — 5 venues, 9 weapons, 3 of them free to wield
• The Deep — 4 venues, 9 weapons, 3 of them free to wield
• The Gods — 6 venues, 9 weapons, 3 of them free to wield
• A world sets the language, the venues and the armoury. It never changes the maths.
• A venue nudges the pace and has eliminations written for that room.
• Roughly four eliminations in ten name the weapon that landed them.

• A hash of the seed is published when the doors open, before the field is known.
• The seed itself is published at resolution, with the field and the ruleset version.
• Re-running those three reproduces the card byte for byte, on any machine.
• Nothing is decided during playback. There is no live rolling and no server judgement.
• The fight and the commentary draw from separate random streams, so what the booth says can never change who wins — and adding new lines never alters a past result.

• The entry contract — No $OCH moves. A wager or a jackpot is a number on a card until it is built and tested.
• Membership — Nobody is being charged, and every record still counts.
• The shop — Nothing can be bought and no XP can be spent.
• The weekly Main Event — Members are meant to be entered automatically and the card is meant to run every week whether or not anybody wagered. Neither happens yet — there is no scheduler.
• Prestige — The ceiling is real and levels stop there, but nothing can reset yet and no rank is recorded.
• Unlocks — Every world, venue and weapon is open to everybody for the beta. What the beta hands out is reset when it ends; records are not.
