What is a set in Rummy?

The set is the simplest meld in Rummy: just collect matching ranks. But knowing exactly what counts - and what does not - keeps you out of trouble.

Quick answer: A set is three or four cards of the same rank, each from a different suit - for example, the 8 of hearts, 8 of spades and 8 of clubs. Sometimes called a group or a book, it is one of the two ways to build a meld, alongside the run. You can never have more than four cards in a set because there are only four suits.

What makes a valid set

A set is three or four cards of identical rank in different suits, such as three Jacks or four Fours. Because a standard deck has four suits, a set tops out at four cards. You cannot use two cards of the same suit and rank in one set within a single-deck game, since there is only one of each.

Set vs. run

A set matches on rank and ignores suit; a run matches on suit and needs consecutive ranks. Both are melds, and both remove their cards from your deadwood. Our answer on the difference between a set and a run breaks it down further.

A note on wild cards

In games that use jokers or wild cards, such as Canasta or Indian Rummy, a wild can stand in for a missing card to complete a set. In classic Gin Rummy, though, there are no wilds, so every set is made of natural cards.
