Night Market.

A city that trades back.

Buy and sell four contraband goods, carry them between districts, and anticipate how rival shipments change the market. Credits, cargo, travel and final standings are resolved by the contract in the competition.

Start with your crew.

The operator opens a competition. Four real wallets each enter with 0.005 Sepolia ETH plus gas. Everyone starts at the Docks with 1,000 game credits and 12 cargo slots. The competition starts when the fourth entrant joins. Unfilled lobbies become refundable after 15 minutes. Practice uses labeled bots and local credits instead.

Plan. Seal. Reveal. Deliver.

1. Review district prices, your credits and available cargo space.
2. Choose goods and quantities to sell and buy, then choose a destination.
3. Seal the order during the two-minute commit window. The browser saves your secret before wallet submission; download a backup.
4. Return and reveal the saved order during the two-minute reveal window. Missing a reveal permanently disqualifies your seat from prizes.
5. Resolve once all eligible seats have revealed or the deadline has passed. Anyone can submit that transaction. Travel takes one or two phases; the next phase starts after resolution.

Know what determines the result.

After sixteen phases, wealth is remaining game credits plus cargo at fixed salvage values. Credits and goods are not redeemable for ETH. After the 1% house fee, the net funded pool pays the top two eligible ranks 70/30. Tied occupied prizes are shared. One eligible player receives the net pool; if all are disqualified, entries become claimable without a fee. A prize can be smaller than the test ETH spent on entry and gas.

Retirement and fault recovery.

The house can permanently stop new entry. Existing games and claims remain available. After a phase has stalled for 48 hours past its reveal deadline, anyone can request recovery: normal resolution is retried first. If it succeeds, play continues. If it fails within the fixed gas budget, the affected game’s entries become refundable with no fee and new registrations are retired. Settled claims remain intact. This does not protect against every possible defect.

Current status.

Deployed on Sepolia with test funds. Local tests and read-only Sepolia simulations have passed; live multiplayer validation is still in progress. Shared-market collusion and strategic non-reveals remain risks. This is experimental, unaudited software.
