As art collectors, players bid on world-famous works of art. Sometimes the bidding is open, sometimes hidden. If you didn't get anything the first round, you can use clever tricks to make sure the outcome is in your favor—so long as your opponents don't have the same thing in mind and tricks of their own stored up.
The cards in the game show famous works of art from different eras, from da Vinci's Mona Lisa to Warhol's soup can paintings. The back of each card has information about the painting and artist as well as the winning bids for the work in previous auctions. If you can purchase paintings from the same era or featuring the same subjects at auctions during the game, your collection's value will increase dramatically and you'll receive a correspondingly huge boost in points.
