Usually played with two decks of cards and with two to six players, Contract Rummy is a multi-round game with distinct meld-forming requirements for each round. For example, players might have to form threyes3pattie sets in one round and two sequences and one set in another. Players must modify their gameplay in response to shifting contracts, which adds a strategic element to the structured format. The appeal of Contract Rummy is its capacity to test players' flexibility and strategic judgment. Players must carefully control their hands as each round goes on, keeping track of the melds needed for subsequent rounds.
