Is Gin Rummy the Same as Conquian?

Short Answer
No. Conquian is the ancestor of all Rummy games, originating in Mexico around the 1850s. Gin Rummy was created in 1909 as a faster variation of standard Rummy. While both involve forming melds, they differ significantly in deck size, hand size, and gameplay mechanics.

Conquian: The Ancestor

Conquian (from Spanish "con quién" meaning "with whom") is considered the oldest Rummy-style game. It spread from Mexico to Texas and the American South in the mid-1800s. Players must form melds on the table during play, and the first to meld all cards wins.

How Gin Rummy Evolved

Gin Rummy was invented by Elwood T. Baker and his son C. Graham Baker in 1909. They wanted a faster game than standard Rummy that could be played in short sessions. Key innovations included:
