The most basic thing about Gin Rummy is that players take turns drawing and/or discarding cards with the goal of getting certain "melds" and chucking "deadwood". Melds are sets of 3 to 4 cards with the same rank, such as 8♥-8♣-8♠, or are a consecutive set, such as 4♥-5♥-6♥-7♥. Deadwood are cards you couldn't get any melds for and will count against you in the scoring. If you're interested in playing Gin Rummy, Oklahoma Gin is a great place to start.
