Doubleduck

This is a 4-player partnership version of the game Duck Soup. It is played with a standard deck. Each player is dealt 13 cards. The first card in a trick determines if it is a high trick (won by the highest card in that suit) or a low trick (won by the lowest). Subsequent players must follow suit if able, but can always play a card of the same rank as the first card (a "quack"). If there are any quacks, the last played wins. One partner collects high tricks and plays Aces high, the other collects low tricks and plays Aces low. The partnership's score is the number of cards each collected, multiplied together. Cards played as quacks count double.
