Rummy Game is a popular card game that can be played with two or more players. It involves forming sets and sequences of cards, and the goal is to be the first player to get rid of all their cards. Two popular variations of Rummy Game are GIN, which is a three-letter word, and Canasta, which is a seven-letter word. Both versions involve forming melds of cards, but Canasta has additional rules such as requiring a minimum number of cards in each meld.
