In rummy, the joker is a strong card that can be used as a wild card to substitute any other card in the deck. Because of this, players can more easily form sets and runs with thplaywin 567e joker card, which is incredibly valuable. A joker that a player selects from the draw or discard piles can be used right away to form a set or run, or it can be saved for more strategic usage later in the game. Also, jokers can be used to replace any missing cards in a player's sets or runs if they declare "Rummy" and they are in possession of jokers.
