Minus Auction 마이너스 경매
Bid on negative-value cubes. Passing costs chips; accepting hurts your score. Outsmart the room.
Negative-value cubes are auctioned one at a time. Accept = take the cube + all chips others passed. Pass = pay 1 chip.
Consecutive sequences only count the least negative cube. Highest score wins.
