A complete game is played over 13 cards. The goal is to get a score as close to 13 as possible. In case of a right answer, the players score 1 point. In case of wrong answer, they lose the current card as well as the top card of the deck. Thus losing 2 points. In case of lack of answer, the players only lose the current card, and therefore only 1 point.
