President is a card game also known as "Rich Man, Poor Man." In this version of the game, you play against three computer opponents. The opponents have been programmed to play as realistically as possible. That is, they each play to win for themselves, and they cannot see any cards except their own. In each game, cards are exchanged between players; high cards are passed to higher ranking players and low cards are passed to lower ranking players.
President tracks the percentage of time you achieve each rank and records your highest scores.
