In rummy, melting is the process of forming runs, which are three or more consecutive cards of the same suit, or sets, which are three or four cards of the same rank. Players' odds of winning can be greatly impacted by their strrummylategic decision of which cards to keep and which to discard. Players also need to pay attention to what their opponents are doing because discarding some cards might unintentionally help them create their own melds. When no more moves are possible or a player goes out by melding all of their cards, the game is over. At the end of each round, players' unmelded cards are usually counted against them, though scoring can vary depending on the house rules.
