the gacha

Spin for the real thing.

Pay one posted price and a block that does not exist yet picks your prize. Keep what you draw — or hand it back on the spot for its standing bid, most of what backs it, in ETH. Either way you saw the exact odds first.

Every gacha hides its expected value. This one publishes the solved game — each prize's exact draw chance, the price, and the valuation at which a pull stops losing — free, before you pay. The machinery behind it, and the depositor's side of the table, live at the desk.

Pick a pool

Each pool is one collection with a real floor under it: every prize is escrowed with the ETH that backs it. The state, the count and the price are read live — a dash is a read that did not happen, never a zero.

A pool's existence is the whitelist — a curator opens one and can never touch escrow, a fee or a payout. Want a pool for a collection you care about? Ask at the desk — public, unsigned, free.

The odds, before you pay

Pick a pool above and it is solved exactly, prize by prize — the same integer arithmetic the contract runs, published free whether or not you ever pull. No tier and no payment moves a probability, a price or a payout.

The weight is inverse to the backing: a cheap prize is drawn often, a rich one rarely. Want to try your own numbers — a pool that does not exist yet, a different surcharge, what one is worth to you? The Book at the desk solves any pool you describe.

Before you pay: your draw has a deadline

A pull is two steps, not one. You request, then — later a block that did not exist when you paid decides what you drew — and someone must settle it inside a window of —. If nobody settles inside the window, your fee goes to the depositors and you get nothing.

This page settles for you while the tab is open — leave it open until your receipt shows. A keeper and the depositors stand behind it, and you can settle any draw yourself, including someone else's. Once settled you choose — keep the token, or take the standing bid — and your window to choose is —.

The full step table — who acts at each step, which clock it runs on, and why the window exists at all — is posted at the desk.

Pull

This copy carries no ScryGacha address, so nothing here can be paid or drawn. The Book at the desk still solves any pool you describe.

The desk

Everything mechanical lives on its own page: the Book, which solves any pool you describe before it exists · putting one up with your own backing · harvesting fees, repricing and taking a position back · asking for a new pool · and the table of what is settled versus still a knob. If you are the other side of this table, start there.
