The most well-known types are probably the traditional ones, such as Gin Rummy and Indian Rummy. In Indian Rummy, players must create legitimate sets and sequences using two decks₹1500 of cards. Players in this version are required to keep track of the cards that have been played while simultaneously predicting the moves of their opponents, which highlights strategic thinking and memory. In contrast, Gin Rummy is played with a single deck & emphasizes creating melds—card combinations that can be runs or sets—before your opponent does.
