Rummy's history dates back to the early 1800s, and its roots are found in many different cultures and geographical areas. Many historians concur that the game most likely originated from the Mexican game "Concentration" or the traditional Chinesereal rummy cash game "Dominoes," though the precise origin of the game is still up for debate. Rummy developed into a variety of variants over time, each of which reflected the subtle cultural differences of its participants. The versatility of the game is evident in its historical development, as it has been adopted by many cultures and taken on different guises, such as Indian Rummy and Gin Rummy. As rummy spread throughout the world, it became a common game at family get-togethers and social events.
