Every card has a number ranging from -3 to 15. Players can hold a max of three cards. Each round, players either draw a card from the deck or play a card face up. Face up cards are placed in a row next to the deck. If a player plays a card that brings the total value of the row over twenty-one, that player bursts. If a player bursts, the round ends and that player receives zero points. All other players collect the points in their hand.
