To play gin rummy, you need to learn how to deal cards, create sets and runs, and score points. As the name suggests, the game is a variant of Rummy, but instead of laying your cards face up during the game for the opponent’s viewing, you conceal them until the game concludes. Essentially speaking, Gin rummy is a two-people card game where you try to arrange all of your cards into matching sets or runs before your opponent manages to do so.
