After being dealt a certain number of cards, typically 13, each player's goal is to create valid combinations before their rivals do. In order to reduce the total value of unmelded cards in their hands when someone declares rummy, plrumny goldayers alternately draw and discard cards. A point system is also used in the game, with different cards having different values. For example, face cards are worth 10 points, while numbered cards retain their face value. Players must strategically strike a balance between creating their own sets and sequences and thwarting the plans of their rivals. It is possible to learn what combinations other people are pursuing by looking at cards that have been discarded.
