Marketplace Flip · rules docket 02

Know the outcome pathbefore the wallet.

Play a no-value prediction round against a fixed card result. There is no sealed pool, random draw, reproducible selection proof, purchase, or ownership change.

  1. Choose

    Predict the fixed result band. Your choice affects the local score, never the card.

  2. Lock

    Lock the call for this round. No pool snapshot, seed, cryptographic commitment, or selection proof is created.

  3. Reveal

    Flip the fixed example card and compare it with the locked call. No marketplace selection or acquisition occurs.

  4. Score

    Bank local points, inspect the no-value summary, and start the next round.

Eligibility
Anyone can browse and run the fixture. Live entry remains unavailable until an approved collection, tier, listing freshness, liquidity, and exposure policy all pass.
Probability rule
Floor, Core, and Chase are score predictions. They do not change the fixed card result and are not commercial odds or a random draw.
Acquisition rule
A future live reveal cannot be final until the selected listing is acquired or the predetermined failure policy completes.
Custody
No marketplace card is reserved, bought, escrowed, or transferred. Every image and value belongs to the fixture.
Settlement
The reveal is a fixture state, not settlement. A live result cannot be final until acquisition and transfer policy succeed.
Refund boundary
Nothing is charged, so there is nothing to refund. Live reselection, substitute, or refund behavior awaits explicit commercial approval.
Receipt
The local summary records the prediction, fixture result, and points. It provides no selection proof; purchase, transfer, ownership, and settlement remain “not submitted.”

State ledger

Three facts, never one vague “done.”

Committed
The player’s prediction is locked in local state only; nothing is cryptographically committed or sealed.
Owned
No selected listing is purchased or transferred; ownership never changes.
Final
Only the local score round ends. No selection, marketplace, payment, or chain finality is claimed.
