Editing Round 9/Ruleset (section)

=== Auctions ===
Ducks that are not owned by any player may be auctioned off, rules on interacting with ducks notwithstanding. An auction starts with a player placing a bid on an ownerless duck. The initial bid must give a temporary name to the duck, if the duck is nameless; the temporary name lasts for the duration of the auction. A bid must be a non-negative number of quacks, and the bidding player must possess at least that number of quacks among their ducks. If the game state changes such that a player can no longer afford their bid, the bid becomes invalid and does not affect the auction. Bids on a duck must increase the amount bid. The auction is automatically cancelled if there are no valid bids. At the end of the voting period after the voting period in which the first valid bid was placed, the auction concludes and the duck is transferred to the possession of the highest bidder and quacks are deducted. The highest bidder may specify how many quacks are deducted from each duck, as long as the total is the amount of the winning bid.
