When another player goes out, the main goal is to minimize the number of points remaining in hand while combining cards into valid combinations. At the conclusion of their turn, rummy tryplayers discard one card after drawing cards from the discard pile or the stockpile. This simple idea belies the strategic depth of rummy, as players must continuously evaluate their hands and predict the moves of their opponents. Depending on the particular version being played, the rules can change considerably, which heightens the appeal of the game.
