Every card has a number ranging from -3 to 15. You can hold a max of three cards. Each round, you either draw a card from the deck or play a card faceup. Faceup cards are placed in a row next to the deck. If you play a card that brings the total value of the row over twenty-one, you burst. If you burst, the round ends and you receive zero points. All other players collect the points in their hand.
