Rummy evolved into many variants as it traveled across continents, each with its own set of rules & tactics. Players form runs or sets of cards in the traditional version of theरम्मी गमे game, trying to meld their hands before their rivals do. Despite the game's diversification into other forms, including Gin Rummy, Indian Rummy, & others, this basic mechanic has stayed the same. Rummy's popularity skyrocketed in the 20th century, especially in the US, where it became a popular game to play at social events and family get-togethers.
