This is the game of Pazaak, a card game in SW:KOTOR. The object of this game is to get to 20 points or a number closer than the other person's score. You can also add or subtract that number with cards from your side-deck. You each choose 4 sidedeck cards. Once you have used that card, you can't use that card again and you can't play another sidedeck card that turn.
One player lays down a card from their deck, then has the option to lay down a sidedeck card and/or stay. Staying means the score you have now is the score you stick with and you can't play anymore. Whatever that player does, the other player plays. They have the option to play a sidedeck card and/or stay. Who ever is closest to 20 wins.
