A set is made up of three or four cards with different suits but the same rank. A legitimate set, for instance, consists of three Kings from distinct suits: the King of Diamonds, the King of Spades,rummy nabob hack and the King of Hearts. Conversely, a run occurs when three or more cards in the same suit are dealt consecutively. For example, a run would be a sequence such as 4, 5, and 6 of Clubs. Players should always be alert for opportunities to meld their cards & think about what cards they might need to finish their sets or runs because it's critical to recognize possible combinations in your hand.
