A new card game in the successful 6 nimmt! Series.
Each player starts with ten cards in his hand. During the game, everyone must take a card in a stack. But the difference between the numerical value of the played card and the card on top of the stack must be no larger than 10, otherwise we read: "11 takes" and the player must take all the cards in a stack on the hand. Yet it is the goal of the game will be the first to release all his cards. Well then, good luck!
