HOW QUARTERS WORKS

A pay-to-play arcade on Robinhood Chain. Real skill games, a real quarter per play, real pots paid on-chain. Nothing here asks you to trust us: every score is a replay you can re-run, and every payout is a transaction you can read.

Official $QTRS: 0xD60bc940830167e251d1D72e95b6C952BD150f44 (Robinhood Chain), launched through Proof Launch campaign 0x11049000Ac2805Ce0418CB1cF2F342f52205091e. Any other address is not ours.

HOW IT WORKS

YOUR RUN IS SAFE

Once you've paid and played, your run is ours to land. It goes to the verifier the moment the game ends (and on the way out if you close the tab). The verifier keeps every run it receives and retries until it's on-chain, even if your page is gone. A run counts if it reached the verifier within 20 minutes of its coin, however long the chain takes to accept it (THE BOUNTY too, from Monday October 5). If a run we received in time still can't be recorded, the verifier refunds your coin automatically.

PROVABLY FAIR

score = f(committed_seed, your_inputs)   — a pure function anyone can re-execute

Every game core is deterministic: integer math, a fixed 60 Hz timestep, seeded randomness. Scores are never submitted, input recordings are. The verifier replays your inputs against the seed committed before you played, and only a score that reproduces exactly is written to the pot. Every scoring run is published as a re-executable receipt. Don't trust the leaderboard. Re-run it.

Pots fill from play. There is no house seed: every daily pot is 85% of the coins played into it that day, plus the floor's share of THE BOUNTY (10% of each weekly jackpot, from October 5, spread over the following week). Every 3 paid plays also earn a jackpot token.

Names. Boards show wallet addresses unless you claim a name on your player page. A claim is a free wallet signature of the text "QUARTERS name: yourname", so nobody can claim a name for a wallet they do not hold. Names are unique, first come first served, one change per hour.

Bots. Every replay carries your input for every tick, and the verifier reads it the way a referee would: inter-press regularity, decision speed no human has, key-hold durations quantized to exact values, play that starts on tick zero, and unusual volume from one wallet in a period. Enough of those together and the run is flagged: it still goes on the board, marked ⚑, but its payout is held. A person reviews the public replay before settlement and clears the flag if it's clean; a flag that stands pays nothing and the honest players split its share. The analysis rides on every receipt, so you can see exactly why a run was flagged.

WHERE THE MONEY GOES

85%THE POT
7%GAS
8%HOUSE

Payout table, each scoring period: 1st 80%, 2nd 15%, 3rd 5% of the pool. One place per player: your best run of the day is your entry, so the top 3 are three different wallets, and a flagged run holds no place. On a thin board the players who showed up split the whole pool in those same proportions: one player takes 100%, two split it about 84 / 16. The split is locked into each pot when it opens. Only rounding dust goes to the house.

Every quarter splits the instant it's inserted, inside the Quarters contract, in the same transaction. The gas share goes to the verifier's signer, which pays to write scores and settle pots. Pots are balances inside the contract that nobody can withdraw. They pay out only through settlePot, which anyone can call once the day is over and which pays the recorded top 3. A payout a wallet can't receive isn't lost: it waits in the contract for that wallet to withdraw. The house share is the entire business model.

CREDITS & PACKS

A pack is an escrow tied to your wallet that you can cash out any time. Buying one is a single approval: the deposit goes into your tab in the Quarters contract, and a small gas float goes to a throwaway session key that lives only in your browser. That key signs your plays, so a pack means no popups. The session key can only spend your tab on plays; it can't send your escrow anywhere else. Close the pack any time and every unspent wei returns to your wallet, along with what's left of the gas float.

Your wallet only ever pays the Quarters contract. It never sends ETH to an address it doesn't recognize.

THE BOUNTY

This week, until Monday October 5: the first verified Void Rocks run over 50,000 takes the jackpot. Holding at least 100,000 $QTRS when your coin went in, you take all of it, up to 1 ETH; otherwise 25%, and the rest stays for the next winner.

The weekly jackpot, from Monday, October 5. THE BOUNTY runs one game a week, rotating every Monday at 00:00 UTC. The week's top verified score takes the jackpot when the week closes. The schedule is published in advance in the public schedule file.

Getting in. Every 3 paid plays on the daily machines in a week earn a jackpot token for your wallet. A token plays THE BOUNTY at the normal price, 0.0002 ETH. No token? Skip the line at 5x, 0.001 ETH: everything above the normal price goes straight into the jackpot. Tokens end when the week does. Your tokens show next to your wallet on every page.

What fills it. 20% of $QTRS trading fees, through an ownerless feeder that can only pay the Bounty; 85% of every Bounty play; the extra from everyone who skips the line; and whatever last week's winner didn't take.

What it pays. When the week closes, 10% of the jackpot goes to the daily machines, spread over the next week. The top score takes the rest: all of it, up to 1 ETH, when holding at least 100,000 $QTRS when their coin went in; otherwise 25%. What the winner doesn't take carries into next week. Every Bounty coin goes through the open-source JackpotVault contract, which keeps the week's board on-chain and has no owner withdraw.

Review. After the week closes there's a 6-hour window before it pays. Claude reviews the top run from measurements of its replay (reaction times, the score curve, input patterns, the bot checks, the wallet's history) and a person sees the result. A run judged automated comes off the board and the next score moves up.

THE BACK ROOM

The back room is for $QTRS holders: the flagship games on their own higher-stakes cabinets, with separate pots and separate boards. Same rules, same receipts, and a back-room play never mixes with the floor. It opens after $QTRS launches.

CABINET DEEDS

Every cabinet will be owned as an NFT deed. The owner, the operator, earns 15% of every quarter dropped into that machine, paid on-chain at the moment of play. Until deeds exist, there is no operator share: that 15% goes into the pots. No deeds are for sale yet, on purpose. After launch, deeds go to auction one at a time with the machine's actual earnings history attached. You buy a rent roll, not a promise.

STATUS

QUARTERS is live on Robinhood Chain with real ETH, in soft launch. Nine machines are open, stakes are deliberately small, and the floor will grow as the loop proves itself.
