Modern Art is a bidding game designed by Reiner Knizia and first published in 1992 by Hans im Glück in German. Players bid on works of art by five different artists; at the end of each round, they then sell their art. More popular artists' works are worth more, and the value carries over into future rounds.
As soon as a fifth work of art by a particular artist is offered for sale, the round ends (the fifth artwork is not sold). Players then sell purchased artwork back to the bank -- the more paintings of an artist that were sold in the round, the more that artist's paintings are worth. Only the three most popular artists' paintings are worth money; the others are worthless. Ties are broken by a fixed artist precedence. The game has a board to keep track of the value of a given artist's painting. Each artist occupies a column. The leftmost artist is always preferred in case of ties. The number of paintings in the deck reflects this; with the leftmost artist having the fewest paintings, and the rightmost artist having the most paintings.
The game is played in four rounds. In the second, third, and fourth rounds the value of paintings at the end of a round depends not just on how the artist did in that round, but can carry over from previous rounds as well. Players are dealt additional cards in the second and third (but not fourth) rounds.
The player with the most money at the end of the fourth round is the winner.
