Dummy rummy is a variation of rummy for two to four players. It is played with two standard decks of cards, including four jokers, for a total of 108 cards. The jokers and twos are wild. It appears to be of American origin and may be copyrighted.

Each player is dealt thirteen cards. During each hand, the object is to complete the appointed run and kinds, and get rid of as many cards as possible. When one player gets rid of all of their cards, the cards remaining in the rest of the players hands score penalty points. The player who completes all twelve hands with the fewest points wins.

As in most rummy games, melds consist of either sets of equal cards, or runs of consecutive cards. Wild cards may be substituted for any number of cards in a set or run. There are twelve meld sets each player must complete as follows:

If a player is unable to complete the appointed hand, they must try again on the next hand.

A set consists of cards of equal rank – for example three threes or five queens. In this variation, sets may contain two cards of the same suit; i.e., two 9 of hearts.

A run consists of cards in sequence, the cards do not have to be in the same suit, such as 2-3-4-5 of hearts. Aces can be high (J-Q-K-A) or low (A-2-3-4) but not both (K-A-2-3).

Twos and jokers are wild and can be used to represent any desired card.

The player to the left of the dealer begins, and the turn to play continues clockwise. A turn consists of drawing, melding and discarding.
