Suroboruos (2021)

Suroborous is an auction game in which the items you bid on will be worth points only if you bid the amounts shown on these items in future auctions — that is, a card may be worth 10 points, but it will show two circles on it, say 30 and 50. The card will not be worth 10 points unless you bid 30 and 50 in future auctions.

The economy is relatively closed with winning bids going to the auctioneer, and the auctioneer's bids going to the bank; however, if any player bids an amount shown on the card up for auction, that card receives a coin from the bank, covering that number.

When the game ends, players earn points for their completed cards, purple cards with special scoring criteria, star symbols on cards, and a bit for leftover money. Of note, players without at least one star symbol are eliminated. Otherwise, the player with the most points wins.
