The active player each turn draws cards from the deck equal to the number of players but does not look at these cards. He then turns one card face-up and gives it to one of the players, including himself; he repeats this process until each player has received exactly one card.
Each card includes a number from 0 to 5—the lower the better—and might also have an action or victory points! Each time a player receives a card, he checks to see whether his total equals 13 or more. If it does, each other player receives VPs from his own cards. The unlucky player with the total of 13 or more discards all his cards.
Possible actions on the cards include veto cards (in order to say no to a card in the future), 13 --> 18 (raising your bust total to 18), lose your last card, and receive 1 or 2 VPs immediately.
The German title of the game translates into English as 'That takes the biscuit'.
