Auction Blocks is a bidding game for Stonehenge: An Anthology Board Game. Stonehenge is being dismantled, and everyone wants a piece! The thirty stones of the outer ring are auctioned, one at a time, and then the five trilithons. Players place blind bids for a stone, but the bids utilize the trump rule of a trick-taking game. Additionally, a player may include a trilithon card with their bid to nullify that trump rule, making that particular auction a standard blind bid. The winner of an auction gets the stone, which is worth points equal to however many of that stone she now has (×2 if the new acquisition is a trilithon). The winner of the auction gets no new cards, and the lowest non-zero bid gets two new cards; everyone else, one. The first player to 20 points wins; or, if the last trilithon is auctioned with no one getting there, the highest score wins.
