After you take a card, discard a different card from your hand in the face-up pile. On your turn, you can either take the top card on the face-up pile or the top card on the face-down pile. Place the rest of the deck face-down in the center of the playing area, and flip the top card face-up next to it. To get started, choose either you or your opponent to be the dealer, and deal out 10 cards to each of you.
Gin Rummy is usually played over several rounds until one player gets more than 100 points and wins the game. To play Gin Rummy, try to score more points than your opponent by making combinations of 3 or more cards in your hand.
