For rummy to be played successfully, it is necessary to recognize key card combinations. Runs are groups of three or more consecutive cards of the same suit, whereas sets are groups of three or four cards of the same rank but different suits. Players can make welredeem appl-informed decisions about which cards to keep & which to discard by knowing which combinations are most advantageous. For instance, if a sequence, such as 7-8-9 of hearts, does not contribute to any possible melds, it may be more advantageous to hold onto it than to hold onto a single high card, such as an Ace. Also, in different Rummy formats, players should understand the significance of wild cards or jokers. Because these cards can be used in place of any other card, they are very useful for finishing runs or sets.
