In Sinful Rummy each player is competing to achieve the highest karma over a variable number of rounds. Karma is measured in karma points which are achieved from the karma value of cards in your playing area. These cards are typically sin cards which players will play from their hand to their playing area which represents the player choosing not to succumb to the temptations of the 7 deadly sins. Playing sin cards can help you invoke special abilities called divine favors. During a round players will be trying to empty their hand because any cards left in your hand will likely cause you to receive negative karma points. The game ends after a scoring round in which a player achieves 100 karma points or more.
