THE RULES.

Last updated August 24, 2026

Ranking

Rank equals cumulative successful purchases in the round, in integer minor currency units, descending. If totals are equal, the participant that reached that exact total first ranks higher. A stable internal identifier breaks the vanishingly rare final tie.

No bids, deposits, or prize pool

Despite the name, each payment is an immediate, final purchase of dynamic promotional placement. There are no losing bids, winner-only charges, random outcomes, or participant payouts. Finishing outside the top three is not grounds for a refund.

Deadline

The server clock controls. No checkout is intentionally created at or after end_at. A verified success event occurring before that instant counts even if delivery is delayed during closing. A success at or after that instant does not count and is submitted for a full refund.

Visibility

Live spend is confidential until reveal. BidBlind may hide or suspend unsafe listings without changing the immutable financial record. Abuse, chargebacks, fraud, or payment errors may lead to removal and provider action.
