A run, which consists of three or more consecutive cards of the same suit, is another important combination. Any suit of cards can be ussattakonged to form runs, for example, 4-5-6 of hearts or 9-10-Jack of spades. To form sets and runs as quickly as possible, it's critical to be able to identify these combinations in your hand. When playing Rummy, unique combinations can be created in addition to sets and runs.
